Breaking: Production Chevy Volt to be Revealed in September!
July 7th, 2008 | Posted in: Design
Reuters has just published a report entitled "GM readies Volt unveiling to shift focus from crisis".
The report cites anonymous sources within GM as acknowledging that the production show-room ready version of the Chevy Volt will make its first public appearance in September.
It was specifically mentioned that the car will be finished in August and may debut at GMs 100 year anniversary celebration, the specific date of which is Septmeber 16th.
Another interesting fact told is than the Volt will apparently make an appearance in the action movie Transformers 2 set for release next summer.
Well it looks like we finally know just when we will see the car we all cant wait for, and its just 64 days away.

Good news!
July 7th, 2008 at 4:17 pm
bring on the volt, and a tranforming volt at that, sweet.
July 7th, 2008 at 4:22 pm
What great news to come home to!*
*I’ve been away for about a week, in case anyone’s noticed
July 7th, 2008 at 4:23 pm
Yeah, Volt!!
July 7th, 2008 at 4:24 pm
This is great news…… BUT, it reminds me of the movie Tucker where they didn’t have a final, working design and example before it was introduced to the public. As one who has lost tens of thousands in GM stock, you know what I’m hoping for. I hope it’s a go for the REAL Volt and not just a publicity maneuver. As usual, I’m cynical
July 7th, 2008 at 4:30 pm
Just be sure they introduce it in the U.S. first. Not in Paris or else where.
July 7th, 2008 at 4:33 pm
Welcome back! I noticed you were absent, nasaman. Statik and Tagament kept things going for you. Now that you are back, maybe you could keep the lid on things and keep us on track.

That’s your name and you can’t help it. Just be cynical.

Where is the 100 anniversay celebration going to be held?
Will VoltNation be meeting there?
July 7th, 2008 at 4:44 pm
Great News! Now, when does Lyle get to try it out?
July 7th, 2008 at 4:47 pm
Excellent news, however:
some say its to take attention away from the financial state of GM, but I do believe its a good idea to get people excited and more informed about the success of this technology.
Too often we hear: oh well the volt is just unproven technology, but in testing we’re hearing the batteries are exceeding design expectations. Generate excitement through this release in Sept, garner support for tax credits to overcome SHORT-TERM pricing problems [lack of mass production cost savings]. Ensure this car gets to market so we don’t have to pay a $550B oil tax to other countries!!!!
July 7th, 2008 at 4:48 pm
I hope there will be another Volt Nation to boot!!
July 7th, 2008 at 4:54 pm
A Volt as a Transformer? Nice!
July 7th, 2008 at 5:01 pm
Anyone reading this post and being cynical needs their head examined. Coming out early in this gas price crisis to further beat the competition is just what GM needs.
Tying in with Transformers 2 is a brilliant marketing maneuver! Kudos to who ever thought up that idea. It makes perfect sense given their relationship in the 1st one, especially if its a major character in the story, and particuarly if the Volt character shares screen time Megan Fox when most eyes will be glued to the screen.
July 7th, 2008 at 5:03 pm
Sorry didn’t notice you were absent. Who are you anyway? Are you new here? Check the FAQ before posting. hehe Just kidding. Welcome back!
July 7th, 2008 at 5:06 pm
If the new Camaro transformer was named “Bumblebee” will the Volt transformer be named “Tazer”? Will he get his power from the “cube” or the “grid”? Hey it’s five o’clock and I’m brain dead…
July 7th, 2008 at 5:17 pm
My guess is they will destroy it like they did all of the GTOs in the movie.
I want to see the VOLT DANG IT!!!!!!!!!!!!!!!!!!!!!!
July 7th, 2008 at 5:17 pm
“Another interesting fact told is than the Volt will apparently make an appearance in the action movie Transformers 2 set for release next summer.”
That’s a great promotion. Next they need to make a pace car for NASCAR races or at least showcase at those events.

Transformer exposure did much for the new Camaro. Hopefully the Volt looks as close to the concept as the Camaro does.

If you would have read my whole posting, you would see how pro-Volt I am. Cynical yes…but pro-Volt
July 7th, 2008 at 5:50 pm
I figured they would unveil the Volt prior to the Paris autoshow.
July 7th, 2008 at 5:52 pm
If the Volt is going to be in the transformer movie, will it be a step-up or a step-down?
\Ba-dum-dum. Great to be here. Try the veal…
July 7th, 2008 at 5:56 pm
WooHoo! Can’t come soon enough for my liking.
July 7th, 2008 at 5:59 pm
Great news Lyle. High five.
Way to go GM, right on schedule, yes?
Early adopter standing by. Means we’ll have some new pics soon. Can hardly wait.
July 7th, 2008 at 6:12 pm
And WHEN are we actually going to be able to get one? And WHAT are they going to do to keep the (leaky) boat afloat until then? The Beat in 2012? And how does THAT help?
I’m struggling to stay positive here guys. PLEASE give me something to work with.

Side note, what happened to the “production version” only being days away, like a month ago?
July 7th, 2008 at 6:22 pm
I have been working on a Volt model using available design details. I’m sure the production Volt will be quite different but I’m giving it a shot anyway. Keep in mind it is a work-in-progress.

Question: Is Chevy dealers now taking in reservations for Volt now that it will start selling in September? I guess I will have to spend 8 dollars of gas to the dealership to find out tomorrow.

As I recall the only thing about “days away” that was said was the production version would be at Paris. That left only a couple high profile events: 4th of July and GM Centennial to reveal the darn thing before Paris

Great job on that rendering. That’s very close to what I’d imagined it would look like from the peek-a-boos I’ve seen. I wonder how many would complain if this is in fact close to what the prod. will look like?

“As I recall the only thing about “days away” that was said was the production version would be at Paris.”
I guess I was thinking of Wagoner at the annual meeting the first of June. He said, “the Chevy Volt is a go”, and “we intend to show a production version of the Chevy Volt publicly in the very near future, and we remain focused on our target of getting the Volt into Chevrolet showrooms by the end of 2010.”
I think alot of people thought that meant a few weeks…there was alot of speculation on the July 4th. Maybe “very near future” means different things to different people.

I posted my model to the Design sub-forum so modeling discussion can be continued there without hijacking this thread. I’m also looking for feedback from anyone on design details.
As far as the Volt being revealed in Sept., I hope everyone keeps their expectations in check, it’s going to look like a car. I predict it’s going to be like an Apple product announcement, fevered hype before, disappointment (from the design side) after and eventually the product actually does better than expected, hopefully.
July 7th, 2008 at 6:52 pm
Please let GM show their battery testing results. Lithium battery life is dramatically affected by temperature, current, swing of charge/discharge. I have two A123 batteries in my hand, one tested at 30C constant temperature, one tested in a chamber where the temperature varies between 45C and 10C (linear temperature change and 10h each loop). You know what, the first only loses 10% after 1000 cycles while the second one loses 42%. Because it is very very expensive to keep large battery at constant and uniform temperature, GM can’t convince me that their battery (whether A123 or LG) can last 15 years. Their commitment is NOT sincere and the recent WSJ comment makes some sense to me. I can tell you that A123 battery perform very poorly below 0C while LG battery perform poorly >45C in terms of battery life. I have PhD in lithium battery materials and my advisor is a leading scientist in this field. I have tested batteries from all major companies and my first-hand experiences tells me it is extremely difficult to ensure 15y service life.
Recently I talk to Dr. G. Abbas of GM, who does not trust this at all, he told me people should and will have to tolerate the facts that battery won’t last 15 years and battery failure risks will always be there. A leading LBNL battery expert (Aussie) also said that there is no hope in lithium-ion battery powered vehicles. This is the main reason (range is another one) Honda does not do EV, and Toyota is extremely cautious about EV/PHEV. Both companies have lots of battery experts and they are constantly evaluating Li-ion battery, so they have real projection whether this will work or NOT.

Cool I’ll check it out and give me 2p, lol. Will be interesting to see how your model shakes down compared to the real thing.
July 7th, 2008 at 6:55 pm
I hope the Volt wins an Oscar for best performance by an automobile.
Hey Volt - don’t get too “Hollywood” on us.
July 7th, 2008 at 7:07 pm
One more thing, to get an EV/PHEV battery, you need to put 100 batteries in series in order to get a voltage of 300-350V. When so many hooked in series, the weaker one tend to get even weaker and BMS has to work very hard to compensate for the loss of capacity in weaker cells or the weakest one get reverse polirization and fail, which may lead to overheat and fire, so the manufacturing is very demanding in order to ensure battery consistency.
Lyle, please do us a big favor and have GM address those issues, if they are really sincere, ask them to publicize the capacity loss afte extended mule testing. I sincerely hope they will succeed, but do not want to be duped!!!! They owe everyone here an explanation.

They owe you an explanation apparently. I don’t feel the need for one. I really don’t give a rip if the battery fails after 3 years as long as the warranty replaces it.
Thermal runaway is supposedly impossible for this battery chemistry as well. If your research data contradicts that then I would be publishing were I you.

I think I read something about this 6 months ago on this site. It had to do with battery pack management. I seem to remember separating cells into groups, or something like that. I didn’t bookmark it, but I’m pretty sure the pack suppliers are addressing this.
There’s tons of low level software (a.k.a. Firmware) all over the Volt. If anything delays the Volt, it will be Firmware, not the batteries.
July 7th, 2008 at 7:27 pm
to Battery Expert
Do you think GM and partners are handing out the chemistry of their Volt batteries? I don’t think so. How you can evaluate those batteries without the actual composition is beyond me. Also, I think GM is saying the Volt battery will last 10 years,not 15 years.
July 7th, 2008 at 7:30 pm
Battery Expert. I’m not concerned with a 15 year life cycle. I get new vehicles every 3. I’m sure 10 years is enough life for most clients.
Perhaps you should contact GM if you have contributions to make….being your an expert.
Can you post some of your experiments showing real world temperatures effecting the battery pack…with the same technology GM is using. How old is your data? Thanks for sharing any information you may have to help us better understand.

I am a loyal GM customer, and I devoutly hope that they succeed and survive. On the other hand, I am beginning to feel like the mythical donkey, and the Volt is the carrot hanging from the stick out in front of me. It sure looks good, but now matter how hard I try, I can never quite get to it.

Battery Expert: Excellent post. Opens up a can of worms that we need some clarification on. Stuff that you would think would have come out by now if GM already knows.
My question or thought is that when GM says end of life that might actually be the batteries real end of life. We have assumed maybe incorrectly that the 40 mile range at end of life was still using the 50% range of the state of charge. It sounds more reasonable to think that maybe the end of life means you now are using 100% of the battery to get the 40 mile range.
GM any comment on this.

Personally, I have always found the idea of being loyal to a company a bit strange. This sort of goes against competition, free markets, capitalism, etc. Also, there is plenty of evidence that GM’s bean counters aren’t very loyal to their customers.
But having said this, I admire GM for sticking to their schedule on the Volt. They have said 2010, and it looks like they’re sticking to it. I would bet that many people are working long hours, so we should be thankful for that. Fall 2010 looks like the end of the carrot & stick scenario.

BatteryExpert — Doesn’t the Tesla roadster use the type of battery you describe? Is it subject to these same failures?
July 7th, 2008 at 7:55 pm
Well my brother sent me an email this morning. He said some high level GM dude on the west coast said they were having troubles with the batteries. I told him I had not heard about it. Now I have. He said it was on radio news. I have no idea what kind of station it was on. I
would suggest that each of you search for that kind of news. I have played this game before. Just because it gets said on TV, Radio or on this site it does not mean it is true.

————————————————————————————–
I’m no battery expert, but I have heard that limiting the swing of the battery charge and discharge has a lot to do with battery life. Specifically, the Volt’s battery swings no lower than 30% SOC, and no higher than 80%. See this article from last summer for details:
http://gm-volt.com/2007/08/29/latest-chevy-volt-battery-pack-and-generator-details-and-clarifications/
Did your 1000 cycles test limit the swing similarly?
Also, remember that the Volt’s battery pack is liquid cooled, so I’m not sure if it will reach 45C that often.
Hope thie helps,

The “high level GM dude” was probably talking about the recent recall on the hybrid battereis used in the Vue, etc., but who knows…
July 7th, 2008 at 8:08 pm
#55
I think you’re right. The batteries used in the Vue were Cobasys and the failure rate was high, it was discussed on this site.
July 7th, 2008 at 8:09 pm
Better sooner than later. They should also begin to sell them as soon as possible. I don’t know if GM waits to sell vehicles only after a sizable inventory is accumulated, but the Volt should begin to move into the public’s hands as soon as it drives out of the plant. GM needs to use the Wii distribution method - make/deliver. I know it’s more economical to deliver in bulk but time is not on their side.
Go GM, go Volt !!!
July 7th, 2008 at 8:13 pm
#38 Battery Expert,
One more thing. GM has said the targeted 40 miles AER is for battery end of life. This means that you would probably get >40 miles AER with a new battery.

Battery Expert
While your title is self proclaimed, I will not question it.
When people think about SECRET material, there really is very little that is out there and it is usually tied to a date (when a mission is, troop movements, trade secrets, etc.). It’s trade secrets I would be concerned with here. A lot of intel is gathered through “open sources” such as blogs and the internet and so I would be wary (if I were GM) about what is released and when.
I see no reason why GM or their battery suppliers need to provide us, or anyone else outside of this project with the specifics of what they are doing in the lab prior to the final release. This would be foolish and would only show their hand to other “interested” parties, allowing them to catch up. General information like “the batteries are doing better than we thought!” are good enough for the consumer. Nobody heard of the atomic bomb until after we destroyed a city with it. How long did it take before it fell into the hands of the Russians?
If you want to know more, go apply for a job at GM and submit yourself to a background check so you can have clearance to see that information and help make it a reality.

#52 AndyChuck asks: “Doesn’t the Tesla roadster use the type of battery you describe? Is it subject to these same failures?”
————————————————————————————–
No, Tesla uses a standard Li/Ion chemistry, similar to laptops and cell phones. Note that laptops and cell phones generally don’t last anywhere near 10 years, so longevity is not as much of a concern for standard Li/Ion batteries.
By contrast, the Volt batteries from LG and A123 are in the Li/Ion class, but use a new and significantly different chemistry, which is safer, and longer lasting.
So all things being equal, the Tesla Roadster batteries would probably wear out sooner. However, with a 220 mile range, the number of charge/discharge cycles on a Tesla Roadster will be much less, so it might work out the same.
July 7th, 2008 at 8:29 pm
I look forward to seeing the new design. I saw an interview on TV where the GM Head-Honcho said that it will look nothing like the concept car, which was so un-aerodynamic that the drag was about equal with the car facing backwards or frontwards.
Now what will REALLY impress me is if GM manages to sell it for a price that the Average Joe can afford. Without that, this whole thing doesnt really amount to much does it? Hopefully that’s what the whole “multiple versions” thing is about.
Regarding Battery Expert’s conscerns, one would think that GM would have thought of all of these things BEFORE they committed publicly to absolutely, positively producing this vehicle ( albeit at an un-affordable price). I suspect that they have the batteries sorted, and that the LI batteries DO work, but I guess we’ll see.
Good point by Dave G. about liquid cooling.
July 7th, 2008 at 8:33 pm
Just ran “Lithium battery problems” and “GM Lithium battery problems” and still not finding anything. Doing this on the net is sure a whole lot better than on the phone back in the 70s. Used to take us a week to put out a wildfire like this.

July 7th, 2008 at 9:10 pm
I don’t think demanding that GM do some ’splaining on the batteries is going to get us anywhere. They know what is needed and they can do it or not do it. I don’t see where they have to say squat to us about it. I don’t see where any one of us would bail out on the Volt because GM didn’t satisfy our curiosity either. We don’t run the show.
I do believe they have some serious challenges to work out in the batteries. If my experience with Li-Ion batteries is any indication I’m worried.
But I still want one!
July 7th, 2008 at 9:11 pm
#38 Battery Expert
You have some valid concerns but I think GM has addressed those same concerns. I believe this has driven their decision to utilitize liquid temperature control. They may even need to immediately start the ICE or pre-heat the battery for very cold environments. I assume since you didn’t mention “how” you cycle the batteries, that you cycled them 0% - 100%. This makes a big difference in life when combined with heat. A123 makes power cells and energy cells which differ. Which did you test? Even so, the cells for GM may be different yet.
Strange that before Tesla and the Volt hit the scene, all Toyota would say is that the market did not want to plug-in vehicles when asked about plug-in hybrids. Strange, they wouldn’t have frustrated me and many, many others if the “real” reason was that Lithium Ion was just not practical for EV’s. It’s not hard to believe that Toyota felt that Lithium is not approriate for what has thus far been their version of an EV. What benefit did yesterday’s Li batteries have over a 2.3KWh NiMh that only utilizes micro-cycling? Other than specific energy advantages that are basically meaningless in this scale, I don’t know of any.
The Volt’s original battery criteria was for 10 years of life not 15. So, while 15 years is being mentioned some now, this would only be a pleasant surprise. For most people it would matter. 10 years is more than enough. What energy storage solutions do you think will be avaible to replace the battery in 2019 or 2018? Personally, I’ld rather have a 5 year battery and save a couple thousand dollars if it were an option.
July 7th, 2008 at 9:27 pm
Sounds good, can’t wait to finally see it.
Has there ever been so much demand before by the masses for an upcoming automibile that anyone can remember?

“GM can’t convince me that their battery (whether A123 or LG) can last 15 years.”
GM is not saying that. Lyle toured the Volt battery lab and in a meeting with Lance Turner, he said to Lyle:
“He explained how GM needs to demonstrate that the packs will last 10 years/150,000miles and be able to get the 40 miles range at the end-of-life. Per Bob Lutz at Volt Nation, the packs might be able to reach 50 miles when they are new.”

Battery Expert looks more and more like a fishing expedition from GM’s competition and you don’t even have to read between the lines!
July 7th, 2008 at 9:36 pm
To all people who questioned, here is my reply:
1). Both LiFePO4 and LiMn2O4 are subject to thermal ruun-away, but less likely than metal oxide (LiMO2) based cathode, less likely does not mean they won’t catch fire. The main advantage of those two materials is: they do not release oxygen under abuse, but they do provide lots of energy in short time, combining with air and flammable components, fire is possible, if you do not trust, go and best A123 M32, charge it and short it, you will see.
2). I am sure GM, A123/continental and LG took this seriously, and I am not saying there is no chance they can succeed, but it is very very hard, considering the liability issue in this country, you know what can happen why sth explode on live TV in LA.
3). Tesla is a joke, they put more than 6800 cells, no matter how good job they do, it is beyond the ability of BMS and please mark this post here: Something terrible like fire or explosion is going to happen in 3 years.
4). When the internal GM guy called G. Abbas Nazri doubts it, you know potentially there is a problem. Any battery guy at Tesla or GM, no matter how doubtful he/she can be, you better shut-up or you be jobless and sleep on the street.
5). I will post the capacity fading data in the next few days and will post it here.
6). The SOC swing is 50%, which means the battery total capacity is roughly 18-20 Kwh, it is going to be expensive and if the warranty is only 3 years, GM will file chapter 7 in 2012. Limiting the SOC swing to 50% will help the battery life, is than 2y, 5y, 10y or 15y remain to be seen.
7). I appreciate the enthusiasm of bloggers here, but lots of people are plain s**p*d.
One more thing: If GM can succeed, (I hope they will), when the battery has about 80% range of initial design, there is still big moneytary value in the battery, GM has to decide if they want to take it back by lowering the initial cost or sell the battery by including it into the car price.
As for disclosing the test result, I understand there could be a trade secret issue, but simply by revealing the capacity fading, your competitor may see advantage/disadvantage, but they will not learn the secret in terms of design, BMS, TMS, etc. As far as I can see, in the last Advanced Auto Batt 2 month ago, no company has ever tested their battery pack in a way that simulates normal driving, and there is a 50%(that is how I feel) of failure, so putting up so much c**p by GM is simply irresponsible and resulting backlash will kill them should they fail.

RE: Battery Expert:
Well, I’m not a battery expert (Although I designed fuel delivery systems and the very, very tiny NiCd system that backed them up, but that was 20 years ago and stayed at a Holiday Inn express or something similar, once
but I have to scratch my head and wonder about the purpose of the data being presented.
Just out of curiosity, does anybody out there live in an area that cycles between 45C (113F) and 10C (50F) every 10 hours? The US average daily temperature change is more like ~15C (~30F) each day, not 35C each day. I thought maybe a desert place like Las Vegas might do it, but no, it’s really closer to 15C daily changes as well (scroll down to the bottom):
http://www.city-data.com/city/Cupertino-California.html
http://www.city-data.com/city/Las-Vegas-Nevada.html
So, if the A123 loses only 10% after 1000 cycles if held at constant temperature, I’m in great shape!
Also, last I checked a day was more like 24 hours, rather than 10, but I have two little kids, I don’t really know, anymore.
Clearly this is accelerated testing data, at something like twice the temperature range (also toward the high temp range) and 2.4x time.
There’s too many variables to actually DO what I’m going to do, but I’m going to do it anyway just to prove a point. If I take a linear fit and if constant temp =10% degradation and 4.8x “stress” (neglecting that 45C is way over most maximum temps in the US) = 40% degradation then… Ooops, there’s not enough data to do anything like that. How about if I just take out the 2.4x time factor then, hmm, 16% degradation after 1000 cycles, maybe? What about the 2x temp variation? 13% after 1000 cycles? You’re all going “that doesn’t make any sense” because it doesn’t. The two points are so far outside “normal” that you have no idea where “normal” falls between them without more idea of the shape of the curve between the points. Linear? Logarithmic? Who knows, and it makes a big difference. Maybe the same or another battery expert would like to shed some light on accelerated life cycle and temperature testing of Li-Ion formulations and how it relates to actually expected temperatures and cycles.
Nevertheless, given the climate data, it doesn’t sound like keeping the batteries well under a 35C “daily” range would be all that hard. Just a big heatsink to keep them pegged to outside temperature… With water cooling I would think that would be a snap.
Oh, I see another post from battery expert just before mine (took a long time to write mine but I think it still applies

This should probably go in the last thread about solar power, but it’s a little dead now:
“General Motors (NYSE:GM) is to build the world’s largest rooftop solar power station at its largest European factory, and is considering similar projects for its other 19 plants across the continent.
The US carmaker will announce on Tuesday that its Zaragoza factory in Spain, which produces about 500,000 cars a year, will be covered by 183,000 square metres of solar panels.
The investment is worth about €50m ($78.5m) and should provide the equivalent of about a quarter of the factory’s power needs at peak times.”

BatteryExpert,
The battery packs do have a thermal management system. I believe all hybrid vehicles have thermal management systems on their packs. Not sure why you think this is a big deal.
As others have mentioned, we have heard there is considerable redundancy in the packs in order to reach the longevity specifications. And, the BMS is designed to treat the pack as gently as possible.
I suspect the BMS can detect and isolate a malfunctioning cell. Each cell will be instrumented. I think the cost and complexity of instrumentation becomes an issue with increasing number of cells, so I believe that is why GM requested smaller numbers of larger cells (as compared to Tesla).
Ultimately, it also becomes an economic and warranty cost question as well — if the Volt packs last 5-7 years and need to be replaced, can GM recycle the old packs and replace them on a cost effective basis? This is a bit of a gamble as I am sure GM hopes costs will go down as volume manufacturing is perfected.

Of couurse it has a TMS and BMS, it is called reliability redundancy.

That is great news! I almost bought a new car this past weekend because I was beginning to doubt the day would ever come that I would see a real Volt. I will definitely hold off at least 64 days before buying anything else; hopefully the Volt will be so beautiful that I can put off the urge to buy another car for two more years.

Do you guys honestly believe that some expert will post here about battery failure and identifies himself an expert. If he really had such explosive (pun) information why does he not help GM directly. I do not believe this poster. He also identifies a GM employee by name. This could easily be verified. There is no way GM would not have tested for this kind of stability. This is elementary stuff. GM would not expose itself this way. It makes no sense.

Lyle,
What you should do sometime, is download all this chatter, strip out the banal banter, keep the serious discussions, organise it all by date and time posted, because:
This site will someday be VERY HISTORIC. No I did not say histrionic.
July 8th, 2008 at 1:44 am
Don’t forget the recent EnerDel interview Lyle did… their packs are designed to be able to cycle 95% of capacity.
I had my last vehicle for 12 years, and my current vehicle 9 years (this October), so I am concerned about battery life….
…. I’m not a big fan of leasing, but if I were an early adopter, I’d consider it, either the whole vehicle, or the battery pack.
Mating supercapacitors with battery systems (as some I think are already doing or has been proposed) may be the key for current battery chemistries to to take some of the load off the battery….

Regarding “Battery Expert”… keep in mind they wrote “I have PhD in lithium battery materials and my advisor is a leading scientist in this field”
I’ve never heard of a PhD in lithium battery materials…. I could see maybe a thesis on the subject, but a whole PhD program on the subject? Googling that phrase doesn’t bring up anything except this thread on gm-volt.com…. also reference to “my advisor *is*” would seem to to indicate, assuming such a PhD program exists, that this person is a doctoral “student” and hasn’t yet got their doctorate.
Not saying this person is or isn’t legit, but like Grizzley, I see red flags. Maybe someone from Toyota?

“Better sooner than later. They should also begin to sell them as soon as possible. I don’t know if GM waits to sell vehicles only after a sizable inventory is accumulated, but the Volt should begin to move into the public’s hands as soon as it drives out of the plant. GM needs to use the Wii distribution method - make/deliver. I know it’s more economical to deliver in bulk but time is not on their side

to Battery Expert,
I’m not a battery expert and I doubt you are. You put down GM’s Volt batteries without even knowing what exact chemistry they are using. I think someone needs to tell you… you are a BS’er. Unless you work with the GM battery team, there’s no way you know anything what GM is using therefore, your test results are fictitious.
July 8th, 2008 at 6:21 am
The battery packs do have a thermal management system — when the Volt is being operated. But, what about other times when the Volt is parked outside in the hot summer (90-110 F) or cold winter (-15 F). What affect will those (or even more extreme) conditions have on the battery life?
I don’t have a clue but perhaps some of you might.

This maybe the reason for the solar panel roof.
When GM said it would keep the interior of the car cool maybe they were talking about the battery pack and the interior cooling is a side benefit.

The Volt’s battery pack is liquid cooled. I would guess the liquid is like the coolant we use today in automobiles. Water cooling would present all sorts of problems.

Can someone clarify what a “production, show-room ready version” actualy is? To me, that sounds like a version of the the car that has all of the aesthetic and mechanical qualities of the final car that you and I will be able to buy in 2.5 years. If that is the case, why will it take 2.5 more years to go in to actual production? Or is it just a shell that looks like the final production car, but missing all the important mechanical parts?

I think the infamous “anonymous sources” is to blame for the misrepresentation here. I believe what is being referenced is GM will be showing a representation of what the Volt will look like.
In no way could a ‘production show-room’ version be ready by September. Evident by the simple fact there is no selected battery supplier, and I’m sure thousands of internal pieces are yet to be flushed out.
Here is the quote in it’s natural habitat:
“The report cites anonymous sources within GM as acknowledging that the production show-room ready version of the Chevy Volt will make its first public appearance in September”

Re Battery Expert.
Sorry folks but if you call yourself a ‘battery expert’ and you are scientifically inclined and probably an engineer of some type, don’t you think that person would have basic middle school grammar and spelling nailed down???
Come’ on, I mean, an individual with those credentials would have to write reports, read data and make interpretations and analysis daily. This individual can’t write and it sounds like someone who doesn’t know the English language very well. That was my first clue….all the numbers and additional nonsense were just smoke-screens. Let’s all allow ‘battery expert’ to fade into the sunset on their own…..
On another note…can’t wait to see the Volt in September.
July 8th, 2008 at 8:21 am
Yes I am sure that “some” dealerships are taking deposits I do not know if it is appropriate to name mine in this forum but we have three deposits on Volts. I am told that we will not be getting to many on the first run but we are a large group so we will get a handful. Be mindful that small dealerships will not be getting any the first year. California and New York will most likely be getting the bulk so the rumour is.
As far as production show-room’ comment historically both ways are correct if they have a complete working version it will be there you will know because the hood and doors will be wide open. If they do just have the production shell it will be what it will look like albeit some minor changes with vender issues might occur. The shell will be closed up and set back on the platform so as to minimize close ups. Since this is the big 100th part my best guess is that the GM top dogs are pushing for a real working model to be on display.
July 8th, 2008 at 8:24 am
Great, cant wait to see what they will show us in Sept…
I’ve contacted some local GM dealers where I am …. and narry a response have I recieved….although since then I’ve had to spend my money (sadly) ….so I’ll have to shut up for awhile now anyways.

#71 Battery Expert:
Here are my detailed responses to your reply:
1). Both LiFePO4 and LiMn2O4 are subject to thermal run-away, but less likely than metal oxide (LiMO2) based cathode, less likely does not mean they won’t catch fire. The main advantage of those two materials is: they do not release oxygen under abuse, but they do provide lots of energy in short time, combining with air and flammable components, fire is possible, if you do not trust, go and best A123 M32, charge it and short it, you will see.
————————————————————————————–
Response: With liquid cooling, there should be no air or flammable components around the cell. Air can enter if the pack is punctured in an accident, but given the location of the pack, this would be a catastrophic accident. Note that conventional gas engine cars can also explode or catch fire in catastrophic accidents.
2). I am sure GM, A123/continental and LG took this seriously, and I am not saying there is no chance they can succeed, but it is very very hard, considering the liability issue in this country, you know what can happen why sth explode on live TV in LA.
————————————————————————————–
Response: The GM pack design seems fairly conservative to me. Liquid cooling, redundancy groups, robust BMS firmware.
3). Tesla is a joke, they put more than 6800 cells, no matter how good job they do, it is beyond the ability of BMS and please mark this post here: Something terrible like fire or explosion is going to happen in 3 years.
————————————————————————————–
Response: This is possible, but remember that the Roadster more of a show car for the rich, so it becomes less likely at these low sales volumes. Also, Tesla’s mechanical pack design is said to isolate each cell’s explosion from adjacent cells.
4). When the internal GM guy called G. Abbas Nazri doubts it, you know potentially there is a problem. Any battery guy at Tesla or GM, no matter how doubtful he/she can be, you better shut-up or you be jobless and sleep on the street.
————————————————————————————
Response: I googled for G. Abbas Nazri concerns, but couldn’t find anything. Do you have a link?
5). I will post the capacity fading data in the next few days and will post it here.
————————————————————————————-
Response: Yes, please do. I’ll be watching for it.
6). The SOC swing is 50%, which means the battery total capacity is roughly 18-20 Kwh, it is going to be expensive and if the warranty is only 3 years, GM will file chapter 7 in 2012. Limiting the SOC swing to 50% will help the battery life, is than 2y, 5y, 10y or 15y remain to be seen.
————————————————————————————-
Response: GM has stated the pack will be 16KWh, and should provide 40 miles of all electric range (AER) at end of life (10 years or 150,000 miles). The swing will be limited between 30% and 80% SOC. I’m not a GM fanboy, but I sure hope they don’t go bankrupt.
7). I appreciate the enthusiasm of bloggers here, but lots of people are plain s**p*d.
————————————————————————————-
Response: Everyone is s**p*d about something. This concept keeps me humble.

If you are serious, then you shouldn’t precede that thought with the banal banter of your comment #91. Lead by example.
Please correct me if I am wrong, but Lyle purposefully established this blog for enthusiasts. He wants to demonstrate to GM the pent up demand for a car such as the Volt. He encourages discussion on all levels. He previously stated that he didn’t want to act as a sensor. Increased comment activity is in line with Lyle’s vision.

My measuring stick is still the concept, regardless of how much GM massages the public up. That is what I saw at the show.

I’m not saying it can’t be different, stuff happens…but it still has to have the ’sweet ride’ factor.

Good point. But trading and payment transfers are not necessarily bad things. What makes this so bad is that it’s a wealth transfer to bad actors like Iran.

With all these experts, are there any experts on Brown’s Gas conversion kits for an ICE car? has anyone tried doing one of those hydrogen conversion kits? Sounds like a lot of BS to me but I figure somebody has gotta know something about it. As far as I can see, your car battery is used to create small amounts of hydrogen using electrolysis. The hydrogen created is used to maximize the efficiency of your engine (I don’t belive you are burning the hydrogen). Anyways, has anyone looked into this or even tried it yet?

Can someone clarify what a “production, show-room ready version” actualy is? To me, that sounds like a version of the the car that has all of the aesthetic and mechanical qualities of the final car that you and I will be able to buy in 2.5 years. If that is the case, why will it take 2.5 more years to go in to actual production? Or is it just a shell that looks like the final production car, but missing all the important mechanical parts?
*****************************************************
It is pretty much what the car will be in 2010. Of course, it gets refined as time goes by.
Getting the infrastructure done on the factory floor for a new type of car, takes a long time. Many new type of machinery to automate the line have to be built. More than likely, at this time, those machines have not been delivered, yet.
How do I know? I worked for GM all my life and have been part of the process many times over.

The volt transformer will be a silent “stealth” recon vehicle, electric power of course.

It sounds as though we are being bombarded by experts today. I especially liked the “hot air expert”, Rashiid. I think we have several of those on board. I am not too sure about our “battery expert”. He (assuming here) sounds a little fishy to me. How can he be testing batteries not even available to the public? I think he might be the real “hot air expert” here, Rashiid. Sorry, but he seems to fit the bill much more than you.

lol Thanks. I guess no matter how good we think we are, there is always someone better.

As the Volt nears each deadline, we will be told by some that it can’t work, that GM doesn’t have enough money, that the batteries won’t be delivered in time, that blah, blah, blah and on and on. The naysayers will be out in force to voice their version of fear. A lot of people have much riding on the failure of the Chevy Volt. They will be pressing their case and trying to instill doubt into our minds. We have to be vigilant and not forget our common goal of ridding ourselves of middle eastern oil sheiks.
Keep your eyes on the ball and keep believing in a better future. Even if the Volt is not all the success we have hoped for, it will be a big improvement over what we have now. It will be a step in the right direction.
The person who said he almost purchased a new car this weekend but could wait to see what the Volt will look like should go ahead and buy the new car. It is a long time yet before most of us will be able to purchase a Volt. That is plenty of time to buy a new Malibu, for instance, and be enjoying the 32 mpg. I drove a new Malibu with a 4 cylinder engine and automatic. It was great. And 32 mpg (with up to 38 mpg) is not bad at this time. I am certainly considering it as my next car. I will buy a Volt, but I still need to think about now and the intervening years until I can purchase that new Volt.

Sounds like a good idea to me.

That 2008 Malibu had a 2.4L 4 cylinder engine and I could not tell that it was not a bigger engine. It had great response for normal driving. It did not “press” it too much, but it had a smooth take off and ride. I certainly would recommend it to anyone looking for a new car. There are many others on the market to choose from, but why don’t we try our best to buy a Chevrolet and help GM at the same time. Let’s start a “Buy American” trend and “See the USA in Your Chevrolet” trend. It will be a way to help the Volt program by putting our money where our mouths are right now. Why give the Japanese or Germans our new car or truck purchase money. Let’s give it to someone that will help the Volt get to market. Let’s give it to GM and get a darn good car or truck in the bargain. (And I don’t work for GM or any dealers, etc.)

DaveP (#72):
Take care when you pooh pooh rapid temperature swings in battery testing. You may be putting down the GM battery tests. There is no way to hook up one of these things to actually see if it will last ten years (in less than ten years, that is). Such unrealistic “compressed” cycle-testing is probably as close as they can come. Until 2020 AD has come and gone, no one can say, for sure, that the first edition Volt battery can last ten years. No. One.
The good news is that by then, no one will care. There will have been a decade of actual battery experience, and continuing research to improve them.
It is just possible that “battery expert” has some valid points which we don’t want to hear; but if so, this isn’t the apocalypse he predicts. If the original Volt batteries manage to last substantially longer than the warranty period; say, five - six years, the batteries available for replacements will be of a much improved design; if only because of the continuing research into Li-ion chemistry which will have gone on since 2010; and cheaper, due to the increased economies of scale. (And also because someone, namely GM, took the plunge and kick-started this whole large-Lithium-battery thing off).

Me.
Side note: I have retired from “calling threads.” I merely ‘post things of interest,’ lol.
Lyle has to pace the flow of information so that the news is in constant flow and people have time to discuss the topic…so he is at a disadvantage, and it’s not really fair to him for me to be all awesome and whatnot.

#113 N Riley —You are a wise man.
If we lose the auto industry to foreigners, I think this country is in big trouble. I do not advocate “buy American” just for the sake of buying American. I say buy American because many of our cars are not just as good, but are better. I’ve driven the 2008 Toyota Camry and the 2008 Honda Accord and I can honestly say the 2008 Malibu is a better car.

” I believe this has driven their decision to utilities liquid temperature control. They may even need to immediately start the ICE or pre-heat the battery for very cold environments.”
——————————-
I hope that the nightly plug-in for charging the batteries will also power up the battery temperature control system.
I can also imagine a computer screen menu where the on board computer would display recommended temperature range and allow the user to override the recommended temperature (within a certain range). The override function would allow people to spend a little more or less money to extend the useful life of the battery.
(I design computer systems for a living…)

Random trivia: Volt was the name of a Transformers Generation 2 Decepticon (bad guy) introduced by Marvel Comics in 1994 that transforms into a Ford coup hotrod. Volt later did switch sides to become an Autobot (good guy).
http://en.wikipedia.org/wiki/Volt_(Transformers)
http://transformers.wikia.com/wiki/Volt
This link has a picture of the toy that was released. Apparently was cool at the time because it incorporated a laser diode and lots of articulating joints. Was a little bit after my time — I had the G1 toys as a kid.

Voltron, of course, is a different franchise. Both originated in Japan. Transformers first originated as a toy line that crossed over into cartoons, comic books and movies. Voltron began as a cartoon.
My God - How many different Thom’s are there on this site????

With technology so new and unknown, I seriously doubt GM would provide an override function to allow owners of the Volt with a software control to vary the useful life of the battery. The warranty would not allow that to happen.

“”"GM can’t convince me that their battery (whether A123 or LG) can last 15 years. Their commitment is NOT sincere and the recent WSJ comment makes some sense to me. I can tell you that A123 battery perform very poorly below 0C while LG battery perform poorly >45C in terms of battery life. “”"”
To be a success in the market place, a car does not have to last 15 years.
If a PHEV battery does not do well below 32 F (0 C), there are ways of dealing with that. While at home, it will be plugged in, so there will be plenty of cheap grid power to keep it warm. While driving, it will be working, so it should be able to keep warm using its own waste heat. While parked, it does not need to be warm. So what might be needed is a heater with a timer to warm up the battery starti
