Will the Chevy Volt Have a “Limp Home” Mode?

October 31st, 2008 | Posted in: Battery, Engineering, Fuel, Generator

Obviously the Volt can be driven without gas, in fact that the whole purpose. The range extender exists only for if you have to go further than 40 miles between charges.

One thing to consider is what would happen if the car ran out of gas after the battery has reached its depletion point, or was in charge-sustaining mode. Since there would still be charge in the battery, it is conceivable that the car could be engineered to dip into that a little and give the driver a “limp-home mode” that might allow 1 to 2 miles of slow driving to get you to the gas station.

The New York Times has just reported that Volt executive Frank Weber mentioned such a limp home mode might be available on the Volt.

Or will it?

I just recently had asked this same question to Mr. Weber’s colleague, Bob Kruse, who is GMs director of Hybrids and EVs.  My questions and his comments follow:

Will there be a limp home mode, if you run out of gas at the same time you’re at battery depletion, allowing the driver a couple of miles of low speed driving?
If it’s your Volt, are you willing to wound your battery for that convenience?

If it happens very rarely it may not impact the cells longevity.
Well I’m the expert on that and is that something that you’re willing to sacrifice, the longevity of your battery in order to overcharge it?

Ideally no, but I think if it were a dire situation the car could give you a big red button on the screen…
I could let you do it but you can’t expect me to give you a life of the car battery of you want to operate outside the norms. But we do have Onstar so if you use it they’ll bring you a gallon of gas.  I don’t know whether were going to do it (have this feature) or not.

So it looks like this idea is probably still up in the air.

Would you want this feature?

    For myself, I wouldn’t want the “limp home” feature. The battery pack will be too expensive to replace. I wouldn’t let the gas tank get that low.

    Unlike others on this forum, I don’t expect the Volt to totally eliminate my oil use, just reduce my consumption by about a factor of 5.

    I think #3 Ignatius put his finger on it.

    Besides, it’s not like this is a step down from what we currently have. If you run out of gas in a regular car, there’s no such thing as a limp home mode.

    PS: I found it annoying that Kruse chose to answer Lyle’s questions with a question. It’s a non-answer. He comes across as a smart ass, or evasive. That’s outside the norm of what we’ve seen from the Volt team.

    I have to agree. Especially with the regards to the answer for the second question. Perhaps Mr. Kruse was very tired or sick? He is not normally that pompous.

    As a motorcycle rider I’m used to using my reserve tank if necessary to get to the station. If the ICE won’t start I’d like to limp home so I don’t have to pay a tow truck to get 1 mile at low speed to the next outlet. I see this as a safety feature and should not void the warranty.

    Now one step further. Volt A won’t start. Volt B arrives and charges Volt A enough to get home. We have talked about vehicle to grid. Has Volt to Volt charging ever been discussed as an option? Maybe in Volt 2.0.

    The Volt should not commit suicide because the driver was stupid, unless it meant the driver would be killed instead!!!

    Remember the three laws of robotics??? (Do a google…)

    Running out of gas does not place the driver in immediate danger, it just means the driver has to make a phone call or walk a bit to get some gas, which is exactly what we do in our current vehicles.

    This is just another example of people demanding that someone else look out for them, and not wanting to take responsibility for their actions…………….

    If you can’t tell from this post, I am against this option, unless it placed the driver and passengers in immediate danger of death.

    Rashiid, Ignatius and all, this feature isn’t intended to save you a few dollars on gas, it’s intended to save you from the aggravation, danger and expense of being stuck on the side of the road.

    Having said that, I agree that it is a totally unnecessary feature–just watch the fuel gauges like you do in any other vehicle.

    How about we have the car be very “verbal” about your need for “fuel” bet that electricity or fossil before you would ever need this silly limp home mode.

    I’ve ridden motorcycles for 20 years and I must admit that I only ever used the reserve 1 time and that was during my first 3 months of riding.

    I wouldn’t want or expect to ever need a Limp Mode.

    Maybe we don’t need to limp home, but. I’m wondering about what the car will do and what I can do if the ICE won’t start – no gas, bad gas, no spark etc. Not just b/c I’m careless and let it run out of gas.

    There shouldn’t be one because lazy people will just be ruining their batteries because the majority of the sheep who mindlessly just drove, are incredibly lazy. They run their vehicles out of fuel by sheer stupidity and laziness.

    We shouldn’t be contributing to keep breeding MORE laziness. If it runs out of gas because you were too dumb to use the fuel gauge, then pay to have it towed, and maybe they’ll lean to not drive it when empty.

    I can see it both ways.

    [1] – If you run out of gas in the ICE car you and everyone else drives right now then your “limp home” mode is you getting out of the car and limping home so it’s really no change from what we’re used to. (i.e. don’t run out of gas idiot)

    [2] – If the ICE in the Volt will not start for whatever reason (no gas, no spark, demons, etc.) and there’s still usable charge in the battery that would allow you to drive the vehicle and you’re in a sketchy situation (it’s dark outside and you’re parked at camp Crystal Lake and you would really really really like to not have to hoof it out of there) then yes I could see the need for a big red button that says “If you want to drive this car right now you hereby risk voiding your GM battery warranty”.

    For me, no. I have a +40mile/day commute and probably always will, by virtue of the fact that I like urban settings and engineering companies tend to like places where they can get cheap space and lots of it. So I would probably always use the range extender for 10-20 miles a day and hence always pay attention to the gas gauge. However, I could see how someone running pure electric 90% of the time because their commute is 18 miles each way might like this. They probably would pay littel attention to the gas gauge, and that day they happened to drive 5 miles out for lunch, this might be useful if they forgot they didn’t have any gas because they hadn’t burned gas in a month.

    Sorry should have clarified. I was suggesting a battery reserve not a gas reserve if the ICE is broken. I know people seem to think this is a million to one and it probably is. Just interested in what if.

    I agree with you about KISS. This car should be idiot proof so maybe a firm line should be drawn for us boundary crossers and limit testers.

    This feature will definitely not be available on the car. It was something they would say ’sure’ to when they first started out…but the cold hand of logic has them now.

    It is similar to the, ‘it is going to go 40 miles at the start…and 40 miles at the end of life,’ they are cutting every cornor they can to squeeze everything they can out of this battery.
    ———
    Here is the problem, I have never owned a car longer than 5 years…I just don’t do it. I don’t like old cars, I get bored of my cars, I don’t like wasting my time jostling back and forth getting my cars fixed. Most new car buyers are exactly like me in this respect…GM knows this.

    Now when/if I buy a shiny new Volt, I know I’m probably only driving it 5 years max and I also know my battery is warranted for 10 years. I am going to be punching the ‘big red button’ for more mileage EVERY SINGLE TIME.

    Even if by some magic I love the car…and I do own the car 7, 8, 9, 10 years…I don’t care about pack conservation, I want that battery dead!

    If GM is costing in two batterys to the price of each new Volt, I am going to do my darndest to get that second battery installed into by car before the warranty is up.

    Basically, that is what GM is doing to us right now in reverse…they are costing in two packs, but trying everything they can to make sure they never have to deliver pack #2.

    If I own the car in year 9 and that battery is still limping in at 40 miles, I’m going to do everything in my power to get a new battery put into that thing. I would quick charge that thing and drain it 3-4 times a day, then turn it on just to see it die…I want that pack I paid for.

    As a matter of fact, you can bet the quick charger will be installed at my house and my work on day 1…and I will be attempting to get 2-3 charges a day out of that thing, it just makes sense…not only do I get the gas savings, but I get the new pack I already paid for down the road rather than me springing 8K for it.

    It would not surprise me to see GM considering killing the ‘quick charger’ altogether (or at least making it a really expensive option), after all its main purpose is multiple daily uses…and that works against GM’s best interest.

    I don’t think there should be a “limp home” mode, but maybe just a “limp to the side of the road out of the way of traffic mode”. Maybe just about 100 feet. If there’s a kid in the car with a stupid parent, I’d at least like to give the kid a chance to get off the highway. I’d even be okay with voiding the warranty.

    Don’t mess with the battery, period.

    I would suggest to GM that they should always reserve .5 gallons of fuel for the ICE for a restricted access “limp home’ mode.

    The standard “Low Fuel” indicator would come on at say, 1.5 gallons. A “Critical Fuel Alert” would come on at 1.0 gallons. Allow the Battery/ICE control system to tap into say, up to .5 gallons of that 1.0, and flash a dashboard light / sound a chime now and then when doing so. Announce (ahead of time) that the car will stop after the .5 gallon is depleted (countdown miles on monitor). Car is now setting at the side of the road. The fuel gauge reads “0″ but the car actually has .5 gallons in the tank.

    ONLY AFTER THE CAR IS STOPPED, allow the driver to now tap that remaining reserved .5 gallons. Access could be through a menu that isn’t presented until the system knows it only has .5 gallons in the tank. When driving on that last .5 gallons, the visual and audible reminders could be amusing. Play an animated GIF of a person walking down a stretch of deserted road (cactus…cattle skulls). A roadside sign mentions xx miles to next fuel station.

I know I am not. I wouldn’t want to chance damaging the battery using it that way. I will be one that has to use the ICE on a regualy basis. The 40 mile range wont even get me to work, much less home.

    I just want the car on the market!! Every little bit I can use electric instead of gas, bring us closer to a cleaner environment for us and future generations.

    he does sound sarcastic, but that could simply be because text has a tone we put to it. His tone could have been more light hearted in the actual conversation. IE banter between two people who know each other well. I don’t think that the idea of a limp home mode, in of itself, is necessarily bad. If used often, it would affect the life of the battery, but if used rarely it would not adversely affect the life of the battery. I think that, depending on the situation, it might be better to have a limp home mode than call for a gallon of gas. There should be an option in the panel, and a warning when it is selected stating that using this feature may cause the life of your battery to be shortened and may void your battery warranty. The car is about options after all, right?

    I never realized that people were intending NOT to have gas in their Volt. It seems obvious to me that you will be frequently required to use gas with the Volt and therefore you will NEED to have gas in the tank at all times.

    This is an interesting engineering question.

    To many people limp home would be a useful and appreciated feature if it saves them a tow truck call which can easily kill a couple of hours, either because of running out of gas, or because of ICE failure. Since gas gauges show zero when you can still go 20 miles, running out of gas is still a common occurance.

    The Volt will have the capability on board to support this feature, if GM decides to program the computer to allow it. But GM risks big warranty claims if it allows people to do deep discharges whenever they feel the need.

    What if you only do it about 3 times? Does that significantly shorten battery life, or do you need a couple of hundred deep discharges to lose 5% of battery life?

    Clearly, GM could get that data (might take a year or two of testing). If a small number of deep discharges is OK, then why not offer 3 mulligans. Your fourth limp home, and everyone thereafter cuts a year off of your batter warranty. The computer could easily track how many limps you did.

    ———————————————–

    I guess I am not high on GM’s ‘lets give this guy a Volt list,’ lol.

    Lutz is already on the record for costing in a replacement pack on every car they sell. For the record, I am not harsh on my cars, I don’t look to break something because I know it will be fixed for free. I am rarely seen at my dealership.

    I think the difference is knowing that you have pre-paid for something that ‘could’ go wrong….and that the person who sold it to you is doing everything in their power to not have to give you what you have already paid for and pocket that money.

    For the record I am not harsh on my cars, I drive reasonably and do all the maintenance. I would not be ‘harsh’ on my Volt either…but lets just say I will be ‘maximizing’ the main selling feature of the car as often as I possibly can.

    The only reason we are getting the ‘kiddie gloves’ on the battery…things like the ‘intellectual property’ of 40 miles start of life/end of life, the limited 40 mile range and now the loss of the ‘limp home button’ is the maindated 10 year/150 warranty in several states. They are doing everything they can to squeeze the original pack to the finish line.

    Without this forced 10year/150m warranty issue I think you would see the Volt using a lot more of its pack capacity and getting more like 60 miles range out of the box easily (and the ‘limp’ button). They are building in as many redundancies as they can to get to the finish line on pack 1.

    The warranty I believe is actually hurting us in this case…it certainly is for the average new car buyer that changes rides every 3-5 years.

    I know I’d rather have a basic 4yr/60m warranty and pay $8,000 less and get the full benefit of the battery pack…most would still get a good 8-9 years of optimal performance and they can decide for themselves what to do when the battery range starts to drain down.

    /maybe while GM is lobbying congress about everything else they should mention having a even playing field on the warranty of electric cars to ICE….thats is like another whole rebate check

    The question I’d like to ask is what happens with your current car when you run out of gas? There’s no safety line there except a gas container, a gas station and pedestrian mode.

    I think that one of the things people are going to have to get used to is always having a little gas/ethanol in the tank. Not just for emergencies, but because for longevity of the ICE it will have to be run from time to time.

    Yes I believe there is. Nasaman has mentioned this several times on this site because this is exactly what he asked Andrew Farah at Volt Nation. Perhaps he’ll jump in on that, but essentially he asked Farah if either system fails batt or ICE will the car function to get you home, and the answer is yes.
    This is yet another reason to use a bus system since if in RE mode the ICE were supplying the battery this fail safe mode wouldn’t work.

    While I think a limp home mode is just silly the issue does raise a good point. I thought most cars have about 1 gallon in reserve beyond “E” on the gas gauge. Maybe having an extra couple miles of electric range hidden for reserve isn’t a bad idea.

    I have been in situations when on trips where I didn’t know where a gas station was and have pushed the limit on my car. I’m sure situations like this happen periodically.

    On another note, since the Volt will come with Navigation, would it be possible for the car to realize that you have “X” amount of miles left of driving capability (Gas/Electric) and notify you of gas stations close by so you won’t be stranded?

    Something like…You have “X” amount of range left but a gas station is within “X-1″ miles…A stop is critical.

    Make this feature optional in the setting of the display and a person can choose to follow the navigation to a gas station or decide to ignore it since they are close to home.

    I think this would be a nice idea if you are below 25 or 50 miles of compelete range.

    Any Takers?

    Since it something that is not desirable from a battery life point of view, then use the strength of the technology and have On-Star do an automatic look up of the closest service station before it runs out of gas. In other words, when the low fuel warning goes on show where the closest station is and guide the user to it. If there is no station within driving distance then On-Star will ask permission to call in for service delivery of fuel.

    Would running it down once or twice over the lifetime of the vehicle really ruin it??? I have never run out of gas in my life, 33, however I have had my car break down a couple of miles from a town. If I had the juice in the battery to limp home and I was forced to walk it I would be furious. The gas tank with a reserve that you can’t use is good analagy. Why?? Electronically limit it through software to x times over the life of the battery, play a message that says to the user that they will be using the emergency reserve using it x more time voids the warranty.

    “Lithium-ion battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:
    Lithium ion chemistry prefers partial discharge to deep discharge, so it’s best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a “memory”, you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it’s ruined.”

    Now off thread. I see the worry about the life of the battery and the built in cost of a replacement as negative points to most as they decide as to buying the volt or not. I would strongly urge GM to give a 75,000 mile free warrenty on the battery and then allow for options of 10,000 more miles of warrenty at a cost of $1,000.00 per increment up to a max. of 155,000 miles. Be assured, I would not purchase additional miles of battery warrenty. I think the cost of a replacement battery will be way down by the time I have driven my Volt 75,000 miles. And I think the replacement will get more than 40 miles per charge.

    ————————————————————————

    Lutz stated that the high thirties price includes 100% of the cost of a replacement battery. If we take this to be a correct statement, rather than Bob just giving a quick off the cuff answer, it gives us some interesting price vs cost data.

    It seems likely that the percentage of batteries which fail within 100k miles will be much lower than 100%. If for the sake of argument 30% fail and each one costs $10k, then GM has $7000 more profit built into the car than the nominal planned profit based on 100% warranty failure.

    I suspect that while they are cranking out 10k cars per year, they will keep the price up, and capture that profit. The extra $70 million will not save GM, but it will certainly make the program look good. When production capacity rises, there will be some incentive to cut the price somewhat, but what will really drive the price down to be correlated with the cost of production will be competition.

    So with no technological advance at all, the price could fall to $29k. If batteries go down to 5K you get a price of $24k, which is not a terrible price for a 100 MPGe car.

    Do you intentionally try to make yourself sick so you get all the health insurance that you are paying for?
    ———————————–
    Obviously I wouldn’t do that, heeh.

    The powertrain and other ‘under warranty items’ are different. Warranty in those cases are given to cover issues on parts that should last in excess of the warranty issue.

    There is a certain premium baked into the car that you pay to have this, like ‘insurance,’ which I have no issue with at all.

    This is exactly like your example of, ‘do you make yourself sick because you have health insurance?’–I do not of course, I pay for ‘insurance’ in case of accident…I do not pay $200,000 for a future heart transplant ahead of time because there is some likely hood I may need a new heart…no one would buy insurance if it worked like that.

    The battery issue is different. In this case you are paying up front, a 100% of the cost of a item regardless if you use it or not. It is paid for…by you. Now GM, having that cash in their pocket knows that if they can squeeze the original pack life through the warranty period…they get to keep that money.

    So why then if you don’t end up using it should you have to pay for it? At the very least, at the 10 year point if you have not blown your original pack, you should be entitled to the swap out for the new one you have already paid for. (I realize that suggestion is as likely as Ralph Nader becoming the next president).

    I’m a ‘fair and balance’ kind of guy in my transactions, I will pay good money for a good product…I’m not looking to rip anyone off, but I expect to get what I pay for.

    ————————–
    Still thinking about the warranty issue. There are several options, but I am not sure which ones would work.

    1. Give you a brand new battery if yours wears out, even if you have 90k miles. I guess this is the scenario Statik is looking at. That would be tough financially on GM.
    2. Prorate your battery life. For example, you go 70k miles, and your $10k battery fails. You get $3k. I dont think this would work, because if you have a car that will not go without a $10k battery, $3k does not make you whole. You would have to put in $7k of your own money to get back on the road, which is speculative for a $70k mile car.
    3. Give you $10k, or prorated value of the whole car, which ever is lower. For example, you go 90k miles and battery fails. A brand new battery seems unfair to GM, but a $1k warranty payment is unfair to you. But if you got $3.7k, which is 10% of the price of the car, it is equivilent to writing the whole car off, because it did not reach 100k. You could use the money to buy a new battery for your old car, buy a new car, or get a scooter. I think this is logical, but perhaps too complex for the market place.
    4. As suggested above, provide a battery with just enough life to get you to 10k miles. Is there really a way to do this? The battery has to have the same KWh storage and KW output as a new one,

    Very interesting problem. No one, not even GM, can anticipate possible emergency conditions that use of the remaining battery charge might save lives. Such as, stranded in a sudden blizzard where a couple of extra hours of heat after fuel exhaustion might prevent death from hypothermia.

    The integral use of OnStar is apparent. I have had it in a previous Chevrolet and it works perfect but was pricey. If it is included as part of the life of the car, it is the best medium to make decisions whereby an owner might be willing to forgo warranty in an emergency.

    I agree that careless fuel exhaustion could be minimized with OnStar warnings but people still choose to push to a station. No way would I give up a warranty on batteries to save a walk to the station!

    Given the choice of a Volt with an emergency bypass switch and one without I will take the one with the switch. Reason: not that I worry about running out of gas as in 60 years it has happened about twice and one of them was when pulling into my driveway at 3:30 AM when no stations were open. No, what I want is the ability to pull out of the traffic lane or to the next off-ramp when the ICE fails. The probability of that happening is likely more than that of running out of gas. I don’t know that much about battery life but I am not convinced that one discharge below 20% is going to hurt battery life. I will even sign the disclaimer.

    —————————

    I know, I know…I like to poke at the soft underbelly of discussions like this. I did install panels on my home…but it is grid tied, so I’m not using batteries to retain the power I generate (and I didn’t buy extra batteries and then leave them at the ’solar store’ in case I need them).

    To me, ideally I want my original battery to last however long, then get the battery that I paid for to last another 8-9 years. Obviously, GM is not proposing this, so I would like my battery ‘warranty replaced’ at year 9ish. (I don’t like the word ‘warranty’ in this case).

    The reality is this. Most Volts are going to push over the 10 year mark without getting a new pack probably, GM will keep the profit on them. Some packs will die/diminish at year 9,10…most probably in year 11,12ish

    At that time, the car is likely in pretty bad shape, I doubt people are going to pay to have the car ripped apart and a new pack put in out of their own pockets at this point, even if the pack is down to $4,000 manufacturer cost…it is probably still alot more for the consumer to have it done by Mr. Goodwrench, probably $8Kish.

    I don’t see a alot of people even considering this kind of repair on a decade+ year old car, at that point these cars will either be scrapped or just used as a standard ICE (if it is still functional), which is pretty wasteful too.

    In theory, the batteries that die in ‘warranty period’ will be the cars that last the longest…and those are the ones that will have some value left in them (for either resale or for driving) after 10 years.

    /whew that was long…that is just my train of thought on it, I’m not as evil as I admit I sound in this thread, lol

    Best case would still be to have the state legislated ‘warranty’ withdrawn…it is a real stumbling block to getting affordable EVs on the road. I know why they did it…to stop companies from taking advantage of the uninformed and putting lead batteries on deep cycles in their cars, that won’t last more than a year or two. Perhaps some kind of pack certification process to make it exempt from the law?

    Not a fan of limp home as described. However a better choice might be that the volt doesn’t let the battery be minimum when it runs out of gas.

    In order to run out of gas, the volt would have to be running in “hybrid” mode. That is using gas to charge the batteries (since it had already used up its full charge). More than likely, the batteries would actually be charged above the redline in this mode (as a normal hybrid does) from things such as regenerative braking etc. Simply having the controller recognize that the tank is very empty (e.g. less than 10 miles till empty), the volt could choose to not turn the ICE off but to purposefully try and charge the batteries with what’s left (that is use extra gas). Your “limp home” would then be whatever you’ve got left on electric. From what I was told about my hybrid, this is actually what it will do if it runs out of gas. It will run until the battery hits its redline discharge, then it will turn off (I was also told not to try it as its very bad for the engine).

    The idea behind this is that at very low gas, any reasonable driver should be looking for a station. However, because the volt has electric if you “use up” your gas quicker you might actually get a better result. If you found a station before using up the gas, you’ve just got a little more battery for the rest of your travel. If you don’t, you’ve purposefully primed an electric limp mode to keep you going and use the other electric generation features of the vehicle to their maximum extent without hurting the battery.

    This type of mode could be very beneficial with a solar panel version since you can continue to gain some electricity to charge the batteries as you limp.

    What about both?

    have a big warning that says your warranty doesn’t cover frequently limping-home. Then when the user activates the feature, record it in the car’s computer. that way the user can get out of those emergency situations, but if they try getting their battery replaced after killing it via frequent limping Chevy can tell.

    It’s good to see most people are willing to take responsibility for their actions and will pay the penalty of waiting at the side of the road for a gallon of gas if they run out. But it amazes me the number of people who still want to be totally taken care of. Really, should the Volt be responsible for guiding you to a gas station when your fuel gauge reads low? Perhaps we should take it a step further and when the car’s clock notices that it is 10:00pm it looks for nearby hotels and Onstar books you a room. Perhaps at 8:00am, 12:00pm and 6:00pm the car looks for nearby restaurants and Onstar calls ahead to pre order your meal. Maybe we can have the Volt learn your commute time and if you don’t start the car by your usual time on a weekday morning the horn goes off constantly so make sure you are aware that you might be late for work. Perhaps when we get Internet connected fridges your fridge can talk to your Volt and the Volt will guide you to the nearest grocery store when you fridge detects you are low on milk.

    I will accept my volt with or without the limp mode but if it is so equipped, I will not use it. I do not let my cars run out of gas. even had one with a broken gas gage.

    Now again off thread

    I totally believe the volt is a COMPLETE GAME CHANGER. I know of only two people that would not want a competitivy priced volt. They are both service engineers for GE Medical and need a van to haul their tools. They will end up with an E-REV van when they are available.

    I also believe GM is eye ball to eye ball with going down the tube and have the built in cost of the replacement battery because of this situation. Hence my earlier suggestion of a 75,000 mile free warrenty.

    I assume [know how to spell assume] Gm believes as I do, and that is that within 5 years of the successfull introduction of an E-REV a car with only an ICE will will be a small portion of sales. [less than 15%] and need sell the volt at as low a price as possible.

    If they have a $40,000.00 volt and the competition has a $28,000.00 simular car then Gm will go down said tube and all of us will be worse off due to losing another vital industry.

    OK, gotta weigh in here with my opinion.

    If the Volt’s battery is worth ANYTHING, there should be NO problem discharging it a bit lower than 30% SOC. We’re talking one or two cycles out of thousands. A good battery like A123 or hopefully LG’s equivalent will NOT be noticeably affected by this sort of thing. If you discharged it to a very low state of charge (like approaching 0%), then you MIGHT have an issue. But even then it’s questionable depending on the particular chemistry (A123 would likely shrug it off). Remember, even at like 3-5% SOC the battery will be able to easily power the vehicle as if it was at 80% SOC. 0% SOC is when the battery can no longer meet its rated output, not literally 0 volts. So going a bit below 30% should not be some huge stress on the battery. People shouldn’t be worrying about “ruining” a battery pack by limping home once or twice. If the Volt’s pack cannot handle that, I am not comfortable having it in my car.

    That said, GM has every right to limit what people do with their battery pack, because GM’s reputation is on the line. I think Mr. Kruse was being a bit dramatic in Lyle’s interview, but in the end he makes a valid point. I see no need for this feature if people are going to abuse it…then we could have a problem.

    I think the underlying topic about the battery is pretty interesting. I don’t think there is mch Lyle can do about the threads, you only can give what you get.

    Fact is it has been along time since the Volt debuted…and it is a long time before any of us get one. There just is not anywhere near enough exciting topics to get us through 4+ years.

    After all, at the end of the day…it is just a car with a battery, pretty dry stuff relatively speaking.

    I think Lyle is doing a amazing job coming out with a new thread like clockwork, especially since he goes to the trouble to run down and interview ‘a player’ at GM for it…even if the guy is clearly being a a**hat to him like you can tell Bob Kruse was for this.

    I was absent from the internet for awhile, and haven’t been able to catch up since; so I don’t know if someone else has already posted this: there is a pretty good treatment of the Volt in the latest issue of Popular Science (with “Your personal tilt-rotor” on the cover); titled “Power Struggle.” The only glaring error I saw was failing to mention that only half of the 16kwh battery capacity would actually be used to propel the car.

    As a bonus, the “personal tilt rotor” is essentially a flying Volt; the props are turned by motors, and the extra power needed to convert from hovering to forward flight comes from a battery — theoretically.

    I’d rather carry a gas can than wreck the battery (I’d try to find an outlet within range of the extra-long extension cord I plan to carry, first).

    Then this wouldn’t be nearly so hard to swallow, would it??

    And then maybe you could chose, do you want your same 40 miles with a pack half the size, or do you want the same sized pack and we’ll give you 80 miles??

    Ok, no one would pick the smaller pack unless they could say it gives you supper performance enhancements or maybe they also give you a $2k GM bucks to spend or something.

    To think that you will be paying 100% for 2 batteries no matter what, that is a bit dramatic. You dont think GM has its engineers/bean counters/lawyers all looking at this situation? If you price the car too high, no one will buy it, if you price it too low and a battery dies, GM loses money. Its all about probabilities, just like your insurance company uses. The price of the car will reflect the percentage chance that a second battery is required. If there is a 100% guarantee that battery #1 will go 100k miles, you will see 0% of a second battery in the price. (and vice versa). Sounds like GM is finding out more through rigorous testing of the battery & software, and that they are much more confident in battery #1 going to make 100K miles.

    Well the nice thing about this forum is that it has variety.

    AND, I am in favor of a limp-home mode, for the reason that I am a person who has run out of gas, has found it a major problem, and would see limp-home as a major asset to the car.

    While I have never planned to run out of gas, or planned for my wife to do so (she has not), or my children (here not sure), it has happened to me and it does happen to others.

    In my defense (against being undisciplined, slovenly, stupid or whatever) let me note that:

    1 — It is my car ( I will have paid for it)

    2 — It is my battery (I will have paid for it)

    3 — The limp-home mode is a feature that can be added through software (so there is no additional manufacturing cost).

    4 — If use of limp-home is a warranty issue, then the number of times it has been used can be recorded permanently, just as mileage has been recorded permanently on my present vehicles. The warranty can take that into account just as it now takes into account the first 36000 miles (or whatever).

    If statik #23 wishes to deliberately overuse limp-home, that will be recorded too :)

    In a more philosophical way, it seems to me that it is to the interest of the Volt community to have a car that is as capable and versatile as possible. We do not have to be parents to the Volt owners of the world. And, if someone buys a car, we can and should keep in mind that it really is that person’s car, not some sort of community property for GM or us all to manage together.

    We don’t really know for sure that GM is building in the cost of a complete second pack. Wasn’t that a rumour? I suspect the truth is that they are just building in the cost of the expected failures. It is possible that they are also being a little bit pessimistic on the failure rate.

    But that is a cost that anyone who buys one of the first Volts should expect; an expensive, high-depreciation, over-promised/under-delivered, and issue-prone vehicle.

    There really is no way around it given that GM has rushed this vehicle out by avoiding their usual checks (by their own admission) prior to reliably testing the battery and using technology that is almost certain to drop rapidly in price and often shooting their PR-mouths off before they really know what is possible.

    Yes, 100% we are paying for 2 packs. It is a dramatic thing, I couldn’t believe it myself when I first heard it…but yet it is true.

    I think maybe you missed the thread that discussed this, here is the exact quote from Lutz himself on September 2, 2008:

    First he says the usual:
    “We haven’t hit any obstacles so far for the batteries,” Lutz said. “They are all performing flawlessly. It’s almost scary we are not seeing any problems with the batteries.”

    Then he says this:
    “We’re being conservative on battery life. For our cost calculations we’re assuming each car will need a replacement during the warranty period.” The Volt will have a 10-year powertrain warranty.

    Thanks for mentioning that noel, I was going to…but I didn’t want to derail another thread, lol.

    Basically what happened is the government has told GM to wait until they at least dole out the 25 billion before they come to the well again…for anything (that will probably take until January 2009 at the earliest).

    The writing was on the wall before that probably because the government was not thrilled that they were being asked to pay for the merge, and GM was already planning to shutter the majority of Chrysler and with that laying off the majority of its employees. Basically the gov’t was paying GM to put people to the unemployment line sooner rather than later.

    I think they considered GM’s plan to have no benefit over that of Chrysler even going Chapter 7 (which is cutting it up for auction and only have the valuable pieces as a continuing operation)…which was GM’s basic plan, thrash up Chrysler and then ’streamline’ their own business with the things of strength/efficiency Chrysler could offer

    The decision to call off the ‘emergency’ meeting by the MEDC (Michigan Economic Development Corp) was another clue that it was, or is less likely now to happen. That meeting was basically, a whole bunch of ‘important’ people where going to get together and talk/complain about the ramifications of the merge. The meeting is now, ’sometime’ after the election…no date offered. ie) dead

    Let me say again, in my humble opinion I don’t believe that limping home will damage the battery pack in any meaningful way. If you did it once a week then maybe there would be battery life issues….maybe. This issue should not be framed in terms of permanently damaging the battery every time you use “limp mode.” It is, however, worth noting that these things can have a cumulative effect, and that is what GM must worry about if they want the pack to reach 100,000 miles.

    Lithium Ion batteries eventually start to lose their efficiency over time when repeatedly charged and discharged completely. To help alleviate this situation, the GM battery engineers decided to never completely charge the battery packs to 100%, and to always leave a approximate 30% reserve before kicking in the ICE to maintain that reserve. The car is then designed to drive for approximately 40 miles within this battery charge range, never completely full, and never completely discharged.

    Furthermore, GM has already stated that using the cars OnStar hookup, the car will know approximately how far away the car is from home, self-determining whether or not to even kick in the ICE. So in this scenario the battery might be depleted to around 25-28% instead of 30%.

    Therefore, would it really hurt the battery all that much if it were drained to 20% of capacity? Even if the feature were used once a year over ten years, how much damage would really be done, if any?

    The feature is worth at least considering and not dismissed outright as the majority of individuals on this board are advocating.

    Further to that…yes, it is two months old (which is not very old), but he said the pack ‘was flawless, no problems, no obstacles’ and that the cost of 2 packs were still going to be in the price, so there is no metric given whereupon we can believe it will be taken out of the equation at any point.

    Thank goodness for next Tuesday! It will be the greatest day ever!
    (Although GM is perhaps reporting Q3 at the same time, so that might be a bit of a downer).

    America has the longest, drawn out production for an election…crazy long. I’d like to echo your sentiment noel, of joy and happiness about not seeing anymore politically charged messages.

    I also don’t know how you can sit through those ‘hate’ commercials for local/state positions, “Joe Flanigan voted against the nursing home on 4th Street. Why does Joe Flanigan hate your Grandmother? Does Joe Flanigan believe in euthanasia for people over 65? Do you want Joe Flanigan killing your grandmother? Vote Mary Smith. Vote for not killing your grandma!”

    Side note on the 2008 Q3 report (which should be Nov. 3rd). Usually we have a disclaimer/calender update a few days ahead of the release…we have not had that. A obscure (and solo) source (Japan’s NHK) reported mid-week that it may be delayed:

    “GM apparently wishes to avoid a possible impact of its business report on the negotiations (the merger). Some earlier reports, quoting people familiar with the matter, said that GM, which is expected to report poor third-quarter earnings in the coming weeks, hopes to have a deal in place before the end of October”

    Obviously the merger is now NOT going down before the end of the month….so I don’t know what this means to the release. Probably we will get a bulletin on it after the market close tonight.

    This feature is just software and it can be managed so that no harm can be done to the battery pack. I think it would be an excellent marketing angle to help those poor souls who would not purchase the car because they can’t plan well enough to keep gas in the tank to get home.

    I’m going to drive my volt mainly on the battery with a small amount of gas in the tank. But what would really help is for the Volt to have a gas only button so that the driver can use up any stale gas in the tank every few weeks without draining the battery first.
    This way there will always be relatively fresh gas in the tank (small amount) when it’s needed.

    “It is not logical to continue to have a limitation that is no longer necessary, just because it was a part of the past.”

    This limitation is inherent in everything that requires “Energy”. No way around it that I know of currently, unless you know of an “Overunity” device of which nobody knows of. That’s why there are gas staion at almost every block and strategically spanned accross interstates.

    Asking to make a “minor software change” requires the retesting of the vehicles drive train under the “Limp mode” to make sure it does not kill the batteries. Of course if you have ever been in product manufacturing you have to do this in cold climates, Hot climates, Humid Climates, cycle the process a few hundred times, put it through accelerated climate changes, envirinmentals and then if just ONE battery fails, you have to go through an entire “Failure Analasys” process and repeat till the “minor change” is qualified for a minimum of “allowable failure loss”. That’s why they took so long to select the first choice battery vendor. Now your going to tell me that will not increase cost?
    I’ve been there, done that.

    Several people have mentioned a reserve tank on motorcycles. Why not have a typical lead-acid car battery connected to the ICE. Normally, this could be used to start the ICE and take the load off the LI batteries driving the car the first 40 miles. The ICE would keep the LA battery charged just like a normal car. However, if the LI batteries were at minimum charge and the ICE ran out of gas, the LA battery could provide enough power to get you another couple of miles down the road (possibly at reduced speed), to a gas station and hopefully out of any possible harm’s way. A typical LA battery weighs about 15-20 pounds, not much really for a nice added ability. :)

    Both “limp home mode” and “40 miles beginning to end of life” will have to dip into the buffer zone (less than 30% charge) at some point, which is not favorable to battery life.

    GM is ok with damaging the battery toward the end of the warranty period so it lasts just long enough, but will not include limp home mode because that’s something that will damage the battery during the warranty period. Tsk tsk, GM.

    The “limp home” mode should be automatic; without user intervention. IF there is enough energy in the battery to safely power the car a bit further (without damaging the battery) then the VOLT would display the exact distance you have left to drive before shutting down. Think of it as a very accurate range display. It would certainly be better than “LOW RANGE” and “VERY LOW RANGE” displays that don’t tell you the actual distance left to travel. While the ICE needs that general warning, the distance calculated from the remaining battery power could be displayed in detail.

    Of course everyone should fill up when “LOW RANGE” appears, but using available battery power to pull off the highway is a safety feature if some owners ignore the warnings and are suddenly stuck trying to get to the next emergency phone box on the freeway.

    Lithium polymere batteries can be completely ruined, and probably will be with one complete discharge.

    “Stale gas” is not going to be an issue.

    I just combed through several pages of related material. And the LOW estimate of gasoline going stale is 3-4 months (stored in a can ~ on a shelf).

    The first element of gasoline degradation (stored in a can ~ on a shelf) is the octane level. The octane will degrade by 1% in 3-4 months. Second is discoloration (browning) in 5-6 months. Third is ‘varnish’ or ‘gum sediment’ formation in (7-8) months.

    As many here have said. The Volt could very well have a 35 mile freeway range and a 45 mile city range on battery power. With the sloshing around of the gasoline, and the addition of 1-2 gallons a month, I don’t see a problem.

    And let’s be realistic, if you own a Volt you’re going to be doing some cruising to show it off.

    Side note on the 2008 Q3 report (which should be Nov. 3rd). Usually we have a disclaimer/calender update a few days ahead of the release…we have not had that. A obscure (and solo) source (Japan’s NHK) reported mid-week that it may be delayed:

    “GM apparently wishes to avoid a possible impact of its business report on the negotiations (the merger). Some earlier reports, quoting people familiar with the matter, said that GM, which is expected to report poor third-quarter earnings in the coming weeks, hopes to have a deal in place before the end of October”

    Obviously the merger is now NOT going down before the end of the month….so I don’t know what this means to the release. Probably we will get a bulletin on it after the market close tonight.

    Not that anyone is following up with this…or is interested, but it looks like my November 3rd call is still accurate…GM I guess is jsut keep results on the ‘down-lo’

    Chevy Volt: Can It Survive GM?

    “Two momentous things are happening at General Motors (GM). One is GM’s electric-powered car, the Chevrolet Volt, which might be a breakthrough machine if it debuts on schedule in late 2010. The other is the deepest financial crisis in GM’s history, which threatens virtually every program underway at the huge automaker — including the Volt.

    But will the Volt survive if everything else at GM goes down the drain? Or if the company declares bankruptcy? In Chapter 11, creditors and a bankruptcy judge have a lot of say over corporate strategy, and it could get hard to justify large expenditures for a futurecar at the expense of mainstream offerings today.”

    Expectations are for a November 9th announcement concerning a Chrysler marriage, a 25 billion loan, and an additional 10 billion in assistance.

    The only one which seems solid at this time is the 25 billion dollar loan. Either way, GM will be taking on more debt (with interest to pay).

    My hope is that GM remains GM as we know it. I don’t like the idea of any more loans (or bailouts) for anybody. If a company can’t cut dead end projects, and rethink their compensation levels, they should simply pay the price and fail. By added outside money, the status quo will simply pull the shade and sink comfortably back into their leather barcaloungers.

Assuming this car has a fuel gauge, I don’t see that happening very happening very often, especially with 40% more driving distance (640 total miles!) than my current vehicle. I think you would have to TRY to run out of gas in that thing, and if you are 1 – 2 miles from home, you can probably find someone who will let you plug it in for 20 minutes to let you get the thing home.

    Watching the gas gauge seems like an easy answer, but it’s not that simple.

    Human beings are creatures of habit. On my gas car I know that it can drive 300 miles tops before I have to refill.

    On the Volt, if your daily commute is less than 40 miles, you might go months without buying gas, and hence pay little attention to the gas gauge. On Star and AAA are a great comfort, but if I knew the car had the ability to limp home, but a lawyer prevented me from doing it, I would be upset.

    The other thing is a limp mode could be use the last half gallon most efficiently and not give you full power until the ICE shuts off. That could be the limp mode and have you really really look for a gas station before all your gas is gone.

    I’ve been simulating the use of my virtual Volt for 2 months now … religiously taking down my car’s odometer reading every morning before first start to get distance travelled the day before.

    I haven’t used a drop of gas in 2 months and I have travelled over 1600 miles, for roughly $30. Yea! What a country! How about you all?

    So, I will personally take a pass on the limp home mode. While I respect the views of other people, consider the following.

    I figure that for most people who are good Volt candidates, the probabilty of being standed in the city is almost nil. After all, most of you will be “filling the tank” (so to speak) every night with a plug. So, the chances of being stranded are even lower with a Volt than with an ICE. ( I admit I did stupidly run out of gas once in 30 years of driving.)

    Also if you run out of gas on the highway on a long trip (because you’ve ignored all the dire warnings screaming at you from the display, you dummy!), then you likely won’t be close enough to “limp” anywhere anyway.

    Non-issue to me. GM has it right again. PPPPPP (see #155:)

    China: Unemployment
    Already, scores of Chinese factories producing consumer goods like toys and plastics goods have shuttered in the southern industrial powerhouse of Guangdong, and thousands of unemployed workers have made their displeasure known with rowdy demonstrations last month.
    It’s a situation that is only going to get much worse in the next few months, as the number of unemployed balloons. According to estimates by the Dongguan City Association of Enterprises with Foreign Investment, 9,000 of the 45,000 factories in the cities of Guangzhou, Dongguan, and Shenzhen – the heart of China’s industrial south – are expected to close before the Chinese New Year in late January. That could mean up to 2.7 million workers facing unemployment, the association said. And they called that number “conservative.”
    China, by its own admission, suffers tens of thousands of what the government describes as “mass incidents,” or protests involving large numbers of demonstrators, and the majority take place in the countryside. Should they begin to occur in the cities, “we would be witnessing the most severe challenge the Communist leadership has faced in many, many years,” says Beijing based scholar Russell Lee Moses. “Stability has been taken for granted by outsiders, but cadres are well aware of how dependent their power is on economic growth. This is a going to be a very real test of the government’s capacity.”

    A potential merger of General Motors and Chrysler has hit an impasse after the Bush administration ruled out funding for a deal, according to a published report.

    This puts any merger of the struggling automakers on hold until after the U.S. presidential election, Reuters reports, citing sources with direct knowledge of the talks.

    The development opens the door for Cerberus, Chrysler’s owner, to restart talks with the Nissan-Renault alliance. Cerberus has seen a deal with the joint venture of Nissan and Renault as an option outside of a GM acquisition of Chrysler.

    _______________________________

    Nissan Motor said second-quarter net income fell 39% to 73.5 billion yen ($760 million) on a severe decline in the U.S. market and as the global economic crisis hit all areas of the auto industry.

    “The global financial and economic crisis has had a profound effect on every area of our industry, with the grip on credit and declining consumer confidence being the most damaging factors,” said Nissan President and CEO Carlos Ghosn in a press release. “Since we see no relief in the second half, we are taking all necessary and responsible measures to protect the company and preserve our ability to rebound when conditions improve.”

I suspect the truth is that they are just building in the cost of the expected failures. It is possible that they are also being a little bit pessimistic on the failure rate.”
    =========================================

    Yes, I agree. What we are seeing is the high cost of a car that is built for the warranty requirements of just one state, CA.

    Maybe GM could price a different car for the other states, should it sell in other states. We could have the standard warranty period of 3 to 5 years and a marked drop in price, accordingly. Then if the owner had a battery with diminished performance, it would be the owner’s choice whether to replace the battery, or not.

    That is, the rest of us would get the benefits of a more sensible warranty period. (CA always thinks that state intervention is better, but sometimes it is not, however well intended.)

    Just because the car has a battery doesn’t mean we have to find stupid uses for it. Since the car doesn’t need the gas generator, lets make it removable so you can take it with you when you go camping. Since the car has a touch screen, why not add a personal ATM feature financed by GMAC bank where you can take out money from anyone’s Volt.

    Link for the China unemployment problems:

    http://news.yahoo.com/s/time/20081031/wl_time/chinasworstnightmareunemployment

    I seem to remember rumors that the Volt battery was $5000, when did it turn to $10,000 ?

    GM is being conservative because no one has used these cells for 10 years, and they did choose the LG cells wich are not as durable as A123 cells.. for whatever reasons.

    Lipos can take the occasional severe discharge, perhaps down to 5% with careful monitoring of EACH cell in the pack.. because if even one cell reached 0% for a short time it will be ruined, and you cant guarantee each cell will reach that point at the same time. You cant discharge your pack to 5% and then let it sit there for 3 days, it will be ruined. So since GM cant guarantee that you will promptly recharge the battery after you limp home….

    Suppose you have a hurricane or other natural disaster and you lose power for 2 weeks, you use the limp home button that time (and you will be tempted, even more if it is a lease) and there goes the battery.

    If GM does implement this, a prominent red sign should permanently light up on your dash.. Battery Warranty Voided, it is only fair to the person that will buy your used Volt. The lawsuits will start flying around like popcorn from unhappy owners facing that big red sign.

    Many cars are driven 20 years, 10 years and it is barely broken in.. I’m sure GM will make provisions for pack replacements, and I am also sure aftermarket rebuilt packs will be available.. the same physical shape may contain fewer high tech lipo cells with the same total capacity and less weight/cost in years to come.

    The temptation to kill that battery before he warranty is over will be strong.. all it would take would be to connect a resistor to the battery and let it drain to zero for a few days.. but I’m sure GM will make it hard to access the true battery terminals. You could also do it by heating up the battery to about 160degF for a few days.. just wrap up the car in black plastic and let it sit in the sun :)

    Statik,
    how about that GM stock? What’s your take on what will happen with the merger. I know how you feel about it, but i’d be interested to hear about what you think will happen
    ————————————–

    How do I feel about it right now I think is what your asking me? (You don’t need/want my overall opinion obviously, heeh)

    I think all the movement the last 4-6 weeks has just been range trade because there is just so much happening all at once. It has been impossible to put your finger on the pulse because of all the behind the scenes action, so the stock has responded accordingly.

    I think alot of people increased positions mid week, thinking the merger was really close ie) ramping news on it & GM being ‘mum’ about their scheduled earnings release…that was seen as a precursor to getting a deal done.

    I think it sold off into the weekend because the merger announcement didn’t happen. Then they switched focus back to owning the shares without merger news, and were leery of holding the stock into the weekend and into a ’surprise’ Q3 report.

    The Q3 is really the wild card here Jon. GM really stepped on the gas pedal to raise cash, retain market share this quarter. It all start exactly on the first of July with all those rebates and 0%…then put rebates on top of rebates in August, and continued thru September trying to raise cash/maintain sales. To some extend, they ‘beat’ their peers in relative sales expectations, but still were down 20% in NA.

    The AVERAGE GM rebate for the quarter was almost $4,000. So how will these massive writedowns on top of plummetting sale affect the bottom line on the report? GM filed that 10-K taking the ‘paper profit’ in a lump some this quarter on pensions…that might make the bottom line look better (maybe, hard to say).

    To tell you the truth I don’t think the market/industry will be looking to the bottom line at all, they will be looking immediately for the cash balance and try to figure out the burn rate…with 14 billion be the ‘death point.’

    Again, GM has done some fancy footwork here by drawing out the remainder of that 4.5 billion line of credit (about 3 billion dollars) which would have been closed by the banks as soon as the Q3 report was out because there is benchmarks in there that GM had to hit or it could be shuttered.

    Still, they had more than a few ‘one-time’ payouts, how much in total and how much paid in this quarter? I dunno. Historically, I’ve been pretty good at pegging quarterly results for GM…this quarter, I would be hesitant to even attempt it…I think I would make myself look foolish. If I had to guess, I’d put cash burn in the 4.5 billion-ish range (depending on if you are disqualifying the 3 billion they ‘cash advanced)

    Oh yeah, the merger…sorry Jon, I got sidetracked.

    I think short term gov’t funded merger is dead. Small chance in the new year for it…if GM doesn’t lay a egg in Q3.

    Small chance they do a merger on the cheap without ‘free cash’ from the gov’t, but with a few billion (3-4) ‘donated’ by Cerberus.

    Most likely scenario (of any of them) at this point is that Chrysler gets carved up/C7. Renault gets the much more efficient truck/mini SUV platform it needs badly, GM gets the vans…they have a mini-war over Jeep (which is the real value). Renault/Nissan offers good cash for Jeep, GM offers up share of GMAC, then it is up to Cerberus what it wants…most likely the 49% of GMAC.

    (Disclaimer: Stuff like this is like trying to guess a coin flip…or read someone’s mind. It’s like reading someone’s mind…it is all conjecture. Nothing like trying to decern the economic tea leaves of a company. In other words, a total WAG on my part).

    It was an ad following a fund-raiser dinner for Kay Hagan held by an atheist society in Boston. The ad backfired, as you said, but not as much as it seems, because it is just one of a long series of ads from both sides with harsh accusations back and forth. Kay Hagan also is not very popular, before or after her candidacy. Dole is in trouble not because of the ad but because she has rarely been seen in NC in the last 6 years and often is not available to people from NC trying to see her in DC. She is seen by many people of all political outlooks as having been invisible. If Kay Hagan is elected, which seems likely, and turns into Harry Reid’s disciple, which also seems likely as she is seen as a weak person, she will be a one-term senator.

    I don’t think anybody has mentioned the fact that the generator starts at, and tries to maintain, 30% battery charge. That means that at 30%, there’s a buffer to provide a useful amount of full-power acceleration. I would expect you to be able to drain the battery down to maybe 20% before you experience limited acceleration.

    That means there’s a ~10% buffer for a limp-home mode that will not affect the longevity of the battery–it’s designed to be depleted this much while accelerating under generator power. I’m not sure why this toolbox from GM fails to mention that.

    I would actually expect that if the ICE doesn’t start, either because it’s broken or out of gas, that you would be able to use up the 10% before the car completely stopped moving. GM wouldn’t even really have to do any extra engineering for this “feature.” You could conceivably go 8 miles in this non-mode.

    So that answers the limp home mode question for me.

    In previous discussions, the question went more like, if I’m only a few miles away from home, can the car delay starting the ICE and allow me to make it back under electric power only. Frankly I think the idea is stupid because 1) it complicates the model of how the car works, and 2) I find it unnerving that my car would know where I live and guess when I’m driving there. But, I will admit that the idea has some appeal because most of the wear on an ICE and its emissions hardware is from cold starts, and if your commute is 42 miles and the ICE comes on every day for 2 minutes to get you home, that’s a terrible duty cycle and it would be nice to just drive those extra 2 miles under battery power.

I have driven a lot out west where gas stations can be a long time coming. I am very coservative with fuel planning and usually refuel at 1/4 of a tank remaining.

    Bob Lutz himself provided insight on this exact scenario during his most recent “60-Minutes” interview, During the interview Lutz states that the real beauty of the Volt lies in it’s SOFTWARE, with smart intuative features that work in-conjunction with the GPS navigation system. So if the Volt “sees” that you are nearly home, it can actually inhibit the ICE startup (within preset limits) in order to get you home to the anticipated charge cycle WITHOUT starting up ICE.

    Due to the warrantee issues I say leave the “limp home” function hidden from the driver. Maybe only a special secrete OnStar function. Let’s say there’s a woman in the car about to give birth and is only a few miles from the hospital. They can call OnStar and be on their way. The violation would be recorded and must be disclosed to the next owner. However, this would be a legitimate reason to use any and all resources available to you.

    As batteries become more powerful and cheaper I see “limp home” hardware as being a very small ICE (.5 L?) that will just be used to get the vehicle home. The ICE will barely be enough to drive the car on the highway at 55 mph. Forget about passing or snappy performance. This will reduce the weight, size, gas mileage and cost of the range extender. In fact, this is the option I want. Just a very small “limp home” range extender with a battery that can move the car around 100 miles. This would reduce gasoline use to very small quantities for the majority of the world’s drivers.

    In a few years quick-charge batteries will become available and be worked into the drivetrain. The small “limp home” range extender will still be needed to transition us to a full EV transportation infrastructure. As soon as there is adequate charging infrastructure the ICE can be left to rust and eventually not be included at all. However, given the vast size of many countries it may take many decades to reach adequate charging infrastructure… Even here in the U.S.

    The one firm belief that I have is that if this care is brought out as a very pricey car then some things should be included as free items. one is On-Star and free service for the first three years of ownership. GM needs to support this car in every way. I for one will be very hesitant to buy the car if I do not get some value added benefits. Having On-Star would benefit both GM and the user by not allowing someone to cause a situation that would be detrimental to the car. Calling for a gas refill or directing someone to a gas station in this situation is positive in all respects.

People don’t need onstar (you have a cell phone), you don’t need “limp mode” (mute point-limp mode = limp drivers), power windows (use your arms they’re fat already), power locks (gentlemen open doors for ladies) power sunroof (sunroof=engineered/eventual leak) or even a 10 speaker stereo (GET AN iPOD or iPhone!)

    I bet if GM sold a stripped down version minus everything I mentioned, they will sell more of that model than of their original.

But, in my opinion, I don’t think a limp home mode would be the thing to do. That is what we have fuel gauges for. GM could give an audible warning when the fuel gets at or below 1 gallon and remind the driver each time he starts the car up until the tank is filled. But some of us here has stated they intended to run the car with no gas or very little gas in the tank. So, for those of you who run out of gas, sorry about that. You will learn next time, maybe. Maybe Uncle Sam will come to your rescue. Just one more thing to add to our Nanny Government. I am sure the Nanny will have something to say about this.

    Limp home is a bad Idea….. Lithium batteries are a lot different from lead acid or NiMH. The lithium battery cannot be discharged beyond 3.1 volts pr cell. To discharge them farther would probably make them useless. In my experience with lithium batteries a fully charged cell will show about 4.2 volts. Fully discharged beyond 3.1 volts is ruined. The volt pack will have about 300 cells, each cell would have to be monitored to stay above 3.1 volts per cell. To try to limp home and drop the cell’s below 3.1 volts each would be really stupid. Just call a tow truck. If I’m wrong about this I would really like to hear from a battery expert.

    I would rather they let you set your own depletion points. that way you could set it to +50% above depletion when you are on a long trip. Then you could run the gas really low and if you did run out you’d have enough charge to get you 20 miles or so.

    I would rather, on long trips run the ICE to keep the car in full state of charge or at least near it. Then when I hit stopped traffic I could shut the ICE off and run on Electric until it cleared.
