Lutz Provides More Volt Details: Photovoltaic Roof to be Unveiled in January, and Volt Development Ahead of Schedule

October 9th, 2008 | Posted in: Features, GM Q and A

After the Volt unveiling the Toronto Star had a fruitful Q& A with GM vice-chairman Bob Lutz.

Lutz told reporters that because things have gone so well, the Volt is actually ahead of schedule. He indicated that he was now 99.9% sure the Volt will be a success, and that as a result it will have a transformational effect on the public’s perception of GM’s technological and environmental prowess.

He also discussed issues being worked out for apartment dwellers, and noted one idea would be to persuade garage owners to set aside an area for car charging and discussed the way public chargers would have to be designed so thieves couldn’t steal power. The charger would have a sliding door that locks the cord in place, opening only when a credit card was swiped.

He also publicly confirmed that GM will unveil the Volt’s photovoltaic roof option at the Detroit Auto Show in January. The roof, he said, will be able to charge the battery from 1/4 to 1/3 over 3 hot blazing days of sun, such as in an airport parking lot, and could function keep the A/C on when parked on hot summer days, avoiding battery draw to cool up the car when the driver gets in.

Lutz also denied present plans to put E-Flex into other vehicles yet, although he remains excited at the prospects for doing so.

Lutz also describes the Volt’s cold-weather algorithm. If the driver turns on the car when its too cold for the battery to properly function, the ICE will go on automatically to condition the battery before shutting off and going to electric drive.

    The article says ““We’re actually way ahead of schedule with everything now because we haven’t encountered any problems,” said Lutz”
    ===============================================

    So I understand the spirit of the comment and am glad to hear it. However, in contrast to Mr Lutz’s statement, we know of problems that GM has encountered, so perhaps the statement means these have now been overcome. I know Mr Lutz is speaking to a general audience, but for those of us who have followed the details I wish he could be a little more specific about what it is that is ahead of schedule.

    My guess is that what the statement means is that Mr Lutz is speaking along a fairly narrow train of thought. He and GM were worried about major unforeseen problems with the Li+ batteries, and that as they have tested prototypes the batteries have done OK. I don’t think he means anything beyond that, e.g., about contracts or production facilities or whatever.

    “Lutz also describes the Volt’s cold-weather algorithm. If the driver turns on the car when its too cold for the battery to properly function, the ICE will go on automatically to condition the battery before shutting off and going to electric drive.”

    This is why there is a need for wireless connectivity and scheduled programming for the car to allow grid A.C. to precondition the compartment and the mechanics (battery temperature) of the car.

    While at home, go to the PC and connect to the cars httpd server and tell it to start conditioning (I have a detached garage). While parked at the mall, tell the car from the in dash touch screen to maintain battery temperature conditions while shopping (which could be any length of time up to a max time). If working a regular schedule, just enter the preconditioning information in to the cars existing scheduler.

    The goal of this car is to use no gas for 40 miles. This should also apply when the car is at origination and destination points that provide grid energy.

    I actually like the idea of the PV roof. I know it isn’t a whole lot of power, but it really can’t add much more than $100 – $200 in cost. My guess is they’ll be using Energy Conversion Devices thin film technology. They recently had ECD PV film put all over one of their roofs in Spain. ECD is also located in the detroit area and has one of the most proven Thin film designs even though it’s not the most efficient.

    I’m pretty surprised that the battery will actually charge 1/4 to 1/3 in a 3 day time period. That means a full charge in 9 – 12 days. Which translates to on a good day you could get %10 more EV miles while your car charges at work. Bringing you up to a possible 44 miles on a charge. I like it even if it is a little gimmicky.

    With GM’s zero landfill manufacturing and the huge solar arrays they are installing on some of their factory buildings (along with the Volt of course), GM will truly be Green Motors.

    The cold weather operation is another demonstration of the advantages of E-Flex.

    Besides being a range extender, the ICE also can be utilized in cold weather to “condition” the battery pack. Again, more examples of how GM is looking to save battery life.

    This is important, because years ago I remember reading that GM felt the EV1 wasn’t viable because the batteries would not last the lifetime of the vehicle. Somewhere in the car’s mid-life, a new battery pack would be needed, and consumers would not be happy with the major expense of the new battery pack (more than half the cost of the vehicle when new).

    Now its nice to think that you could always get the battery conditioned from the grid on a cold day, but for those of us who can’t plug-in at work, or have to leave our car at the airport for several days when traveling, this is definately a nice feature.

    Just another reason why battery-only electric vehicles are not for everyone.

    9 Statik:

    Its sort of a forced offered option. I am sure the engineers were looking at each other at the request going “Are they serious? Its worthless”

    Toyota unveiled a PV roof so the Volt has to offer one as an option. GM’s “green” credibility is hanging by a thread because of the relentless media and environmental group beatdowns. If Toyota unveiled that the plug in Prius had a special Unicorn farts mode then GM absolutely HAS to come out the next day and offer a Unicorn Fart burning Generator option.

    I am glad they are “ahead” of schedule, but I wonder about the photovoltaic roof. First they said it was an option, so not all cars will have it, second, since the suns intensity is different depending on where you live, will it get a stonger charge in the south like southern Texas than it will in the north like the UP of Michigan?

    The sun can get pretty intense here in Houston, and if it can charge the battery faster because of it, it is a great option i can get behind. Although it doesn’t do me any good at work since I park under cover every day, but it may entice me to go and park on the roof of my parking garage.

    It is simply not strong enough to do me much good. I park in the garage at home and at work. The car will mostly be inside. 5 days a week, the car is outside for the 2 hours I am driving. A PV sunroof would be useless to me. However, I am glad this will be an option. I assume most people do not park their car in a garage while at work.

    Can we get any more information about the software algorithms? Maybe a top level flow diagram? My guess is GM could get a lot of free software design consulting help if they asked for it. If this truly is one of the bottlenecks, they could benefit from a very active and interested free software development community. They could register developers (have them sign a NDA, etc.) and set up something like sourceforge. I bet it would take a couple months off the schedule, and translate into some extra cash. As an experienced software developer in a safety-critical transportation industry (aviation), I’d be willing to participate in something like this. Anyone else with me?

    =========================
    Really? So “asking nicely” to set aside those spots is going to be the way to go? Seems like this is a huge issue that is going to have to be overcome. Garage parkers that have say assigned spots with no current outlets? Apartment owners arent just going to volunteer to wire up their parking garages.

    The only thing I could see for this is some kind of portable solution – what that is I have no idea. Leave it plugged in at home during the day then come home, pick “it” up, bring it down and charge the Volt that way, maybe from the interior so it cant be screwed with.

    Wouldn’t it be easier to have a simple circuit that cuts the power to the cord, until you slide your CC? And a simple algorithm that cuts the power if, say, someone unplugs your car and tries to charge his own car?

    I’m glad that GM is making this an option, people should be free to purchase it if they want to. But I’d have to agree with Static that it’s not really practical, considering the cost. On a good day, you can get an extra 4 miles of range from parking in the heat. That amount of electricity off the grid will cost about $0.10. So if the PV roof costs $500, it’ll take 5000 PERFECT days, or 14 years, before you make your money back. This ignores the time value of money which would definitely make this a bad decision.

    If you strongly support PV technology, you’d be better off taking your $500 and spending it on a home PV system, buying stock in a PV company, loaning it your neighbor so they can buy a PV system, etc. Putting it on top of a car is only useful for declaring to everyone else that you are an eco-minded person with some disposable income.

    I think the PV roof is a great safety idea! Every year children and pets die, and a lot more end up extremely uncomfortable, because they get locked in a hot car. My guess is that this will ultimately become a required safety feature. Also, how many times have you needed to sit in the heat waiting for someone? Or even with car trouble on a hot day? I’d rather do it with the air conditioner on and running. So I’m with Texas: Check my option box.

    #9 Statik – As a FYI this is the interview I mentioned yesterday about the plug. The transcript is an edited down version of the actual interview.

    ============================================

    Apartment owners and managers are more competitive than it might seem at first. Good tenants are in effect business partners. If an electrical outlet makes it possible to keep a good long-term relationship, many apartment owners will get it done. It is a minor item in relation to the much larger sums often involved.

    I agree.

    However…hopefully, PV solar cells on the Volt will promote the research and development of the tech for vehicles. I believe that hybrid cars have done a great deal to ramp up the research and development of electrical storage devices…more specifically Li batteries. Heck still within the auto industry, the debate about using large battery packs for cars still continues.

    If the solar panels can actually cool a vehicle, it could become an option for ICE only vehicles. ICE only vehicles might switch to an electrical driven A/C compressors…possibly making it standard for all vehicles.

    Yes…I know that some Volt enthusiasts want to feel “special” with the unique components on their future vehicle. As you may know, volume production can drastically reduce cost of components which makes it possible for more folks to enjoy the tech.

    If you want to save the world AND have the best time value of money result you should buy an old mini truck, do a EV conversion on it, go to the hardware store and get a generator and install it in the truck bed. The whole deal will cost you less than $10,000 and should get you anywhere you need to go for the next couple of years.

    To me that doesn’t necessarily say 3 days, but a few could mean 2 to 4 in my mind so I’ll take the 3 days. And I really don’t think Lutz is saying you’ll go from %25 charge to %33 charge in a few days. That makes no sense, and in reading the actual quote it’s a stretch to assume that’s what he’s saying.

    Not all PV cells are created equal. The thin-film cells which are least efficient are also the cheapest.

    The Mars Exploration Rovers, twice as far from the Sun, get all of their power from multijunction solar cells which were hand-made in a laboratory (don’t have figures, but I bet they were — astronomical ;-) ). It’s even possible that at this moment, there are more multijunction cells on Mars than on Earth.

    In the deep South there are stories every summer of pets and children dying from the heat in a locked car. This is enough to mandate at least the thin-film roof, from a straight safety standpoint. If someone with deep pockets wants more than “up to a mile a day,” perhaps a silicon or CIGS based array could be an expensive option.

    On-board solar won’t really start to be significant in terms of moving the car until multi-junction cells approach CIGS or thin-film pricing. Don’t hold your breath.

    I ride my bike to work. Hopefully I can move out of your hypocrite category now. And I for one do consider the time value of my money because it makes a big difference in deciding between competing options. I understand most people won’t but that shouldn’t preclude us from considering it. But that doesn’t change my conclusion that a PV roof will likely never pay for itself, even ignoring the TV of money.

    All the safety features you mentioned are theoretically available in an EREV without a PV roof. They run off the battery. And I haven’t read the PV will power the AC, only a small circulation fan. In addition there are many other safety features that could be added for $500 (or whatever the final cost is).

    ——————————————–
    Hehe, and I thought I was sceptical.. I think Lutz meant exactly what it appears he said this time. 1/4 or 1/3 of a full charge.

    Here comes the math…look away if you are queezy.

    If you live in the ‘dark’ areas on this map…and it is summertime, you can get that fairly easily in 3 days…without ‘blazing’ sun all the time actually:

    http://cleantechlawandbusiness.com/cleanbeta/wp-content/gallery/graphics-pac-lab/us_pv_annual_may2004.jpg

    Assuming a California/Arizona/Texas type location in peak season, a 1/4 or 1/3 charge is not unreasonable. We are talking about 2-2.5kWh (assumeing 8kWh functioning usage of battery) here over 3 days or .6kWh- .8kWh per day

    You are peaking out, given a horizontal axis in June and July at about 8 hours in the dark areas, so you only need a solar PV collector in the magnitude of 75-100 watts. 1 foot of standard efficiency photovoltaic panels will yield about 12 watts. So, you are only looking at a maximum 3×3 panel on the roof to do the job given the parameters.

    Side note: This is very isolated math…only applicable if you live in the southwestern states and it is summertime, with uninterrupted light. But I think that keeps inline with Lutz statement, ‘3 hot blazing days of sun in a airport parking lot’

    GM knows the photovoltaic will not be very cost effective and that is why GM will offer it only as an option. Those first buyers will more than likely buy that option because for those, money won’t be an object.
    Also, I think,GM will probably advance the production date because they are now more willing to take a bigger risk on the battery. They wanted the extra time to put the battery through longer rigorous testing. This is all happening because of the dire state of the economy.

    The last paragraph of the article was the most meaningful for me:

    Toronto Star: Assuming the Volt delivers on expectations and is well-received by consumers, what else could derail GM’s efforts?

    Bob Lutz: Let us say that over the next 18 months the world goes into a major recession, car sales and fuel use drop dramatically, the steel companies produce less steel and therefore use less energy, China finds its main export markets drying up, so they are into a contraction and use less steel and aluminum and plastic. And at the same time Canadian tars sands come on stream, and coal-to-liquids come on stream. All of a sudden there is a reduction in primary demand in petroleum plus all these additional new supply sources, which were started at the time of $140 a barrel, suddenly coming on stream. And oil drops to $25 a barrel and we’re looking at gas pump prices at $1.25 a gallon. I personally don’t think that’s going to happen, but that would be a dramatic event for the Volt because everybody would say, ‘Ha! Why
    should I bother?’

    Lutz didn’t mention OPEC turning on the spigots to lower oil prices, which they have done repeatedly when alternative vehicles have started gaining a foothold, so I think this scenario is much more likely.

    In any event, since 70% of our oil is imported, it seems like a really good idea for the U.S. government to set a minimum price for oil, and then raise oil import tariffs when the price goes below that point. This way, people like Bob Lutz won’t have to worry about the $1.25/gallon scenario, which means investment and development into alternative vehicles will increase substantially.

    My guess is that the PV on volt will be net CO2 +ve at the end of its life i.e. it will take more CO2 emissions to manufacture it than it will save by making electricity from light.

    I think the PV roof serves two useful purposes. One, it could be used to maintain interior temperature on extreme temperature days. Two it gets the infrastructure integrated into the car from the start, as opposed to a add on later in life.
    What Lutz said about the PV film is where we are today. Look at companies like Konarka or Calyxo that are making some incredible products today. Imagine what will be available in June 2010. Sure some of the claims will be vaporware, but the advances are going to be coming fast and furious with thin film solar. What could recharge 1/4 today might be able to charge 2/3 by 2010.

People are now willing to pay more for a car that gives them “green cred” or just to say they don’t use gas. A car like the Volt that is actually practical for the masses (if priced right) and gives the enviro shine that many people want today, is in a good position to capitalize on the new market outlook, IMO.

    Let say you travel 38 miles to an airport and then park the car for an extended trip. (No plug in available)

    How long will the Lithium batteries hold its 30% charge?

    What happens if you leave your car sitting for longer than that and the batteries are completely dead?

    Will the ICE still start? If not, will you be able to “jump it off” like todays car batteries?

    And then, how long would the ICE have to run before there is enough charge on the batteries to operate the car?

    Options such as a PV roof are just that – OPTIONS. No one should get their panties in a wad because GM offers any particular option. If the owner feels he wants such a option, then great. Myself, I can see some advantages for some people for having that as an option.

    I agree with RB (#26). Apartment owners will try to keep their clients because good ones are hard to find. Plus, they can set-up charging stations and make some money from them. That way everyone wins.

    I would also like to add that in no way do PVs ever make even the least bit of economic sense here…there is zero chance of payback, even assuming 40 years ownership of the car.

    Depending on the state/country, payback is in the 8-15 year range for massively larger residential applications that have scale working for them…and with huge rebates in place and no unique engineering.

    This is a ‘cool’ feature only…which I personally don’t have a problem with. Desire is as good a reason as any to buy a car…after all, a car is a money pit regardless of how you look at it.

    Sidenote: GM is continuing to get obliterated so far today. Off about 25 percent of the high and 18% on the day.

    Open high: $7.36
    Current: $5.64 (-18%)
    Current Market cap: 3.3 billion

    No reason, other than fear of insolvency. I’ll take my Volt to go, ASAP please. Err wait, the short selling ban was lifted today. That being said, I still have zero clue where this is going to end today…could be anywhere. How can ‘regular’ people stomach owning something like this?

    That may still be true for Silicon, which must be heated to high temperatures to produce the crystalline materials which are sliced to make cells.

    Thin films and CIGS cells are “printed” at low, even ambient temperatures, so much less energy is used to make them. Even though they would both produce less energy over their lifetimes, I think the carbon balance would end up being favorable.

    “if i owned a parking lot, and could put in a 1-time cost of pay meters then sit back and let the $ start rolling in, I would”

    I’m afraid it wouldn’t be a one time expense. In addition to the power itself, there’s also the necessity to maintain a data connection for the card-swiper. If you already have a network which can be extended to the garage (along with the power), it probably would be “easy money” … once you get into a total EV volume exceeding 1%; which could take over a decade.

    This is the caveat for all alternatives to plugging in at home. How do you make a business decision for a market which may or may not emerge? I’ve seen at least two generations of far-sighted, too-early, now obsolete electric parking stations going unused. I predict that this time, Business will say “show me the numbers” before tearing up the pavement.

    Since the battery operates at 30-80% charge (50% range), take Lutz’s 30% number times 40 miles. That’s 12 miles from sunlight over 3 days, or 4 miles over 1 day.

    Take 4 miles times 300 average days over the year of driving at least a couple miles. That’s 1200 miles. At 50 mpg that saves 1200/50 = 24 gallons, or about $100 per year in California.

    So, if this option increases my monthly payment significantly more than $10 per month, I would be unlikely to get it from a purely financial standpoint. I’ll bet the option will cost more like a couple thousand than a few hundred.

    Well I have a PV system, costing is not really something I can reasonably do from my residential experience. I would probably put the basic hardware costs at around $1,500 to GM, then the integration costs on top…another $1,000?

    So, probably $4,000-$5,000 to the consumer? Does that sound right? I mean they charge $800 to just cut a hole in the roof of a Mailibu.

    If your curious about net average production per car on a 3×3 PV sheet on top of a car over the year, (assuming horizontal axis and 60% available time exposure), the formula would be as follows:

    102w( 3′x3′@12w/sq.ft) x 365 x 4 (kWh/m2-Mean daily global insolation ) x .6 = 89.3kW.

    Your arithmetic is OK, but I think you start with the wrong assumptions. Perhaps a better way to think about it might be:

    The PV would add electricity when you *can’t* plug it in. It doesn’t replace plugging it in. It’s a supplement.

    We already know AC use affects range, just as with IC engine cars.
    If you have to park in the sun at work, a PV roof might keep the car cool, and/or add charge to the battery. This could prevent you running the AC full blast when you go home, plus perhaps add enough charge to make up for the AC use during the drive.

    Maybe I’m crazy but shouldn’t the volt be out of the reach of “apartment” renters.

    The bigger issue i think is for people who OWN townhouses, they’ll be a larger part of the buying population for the Volt. At least where i am most Townhouses have parking in-front or next to the building usually separated by grass & sidewalk. I don’t see how those existing communities setup plugging stations without doing major renovations. Not only will they have to run dedicated lines from the individual owner’s utilities, but the cost to do it per townhouse would be a couple thousand. Plus what about the communities that don’t have assigned spots? Then what? This isn’t even bringing into account the “association” and it’s rules.
    Running extension cords just won’t work for a majority of people in townhouses, for the simple fact of a cord running across the sidewalk alone.

    Bottom line is people who live in apartments/townhouses where all of their individual space is inside the dwelling and everything outside is considered “community space” are going to have a hard time with this, i don’t see any easy answers.

    Even if you wanted to see it this way, your calculations are wrong. IMO you shouldn’t compute the price of the electricity you are saving but the price of the gasoline you are saving.
    At my local (Italian) fuel prices and considering the fuel mileage of a good efficient car such as the ones sold here (40/45 mpg) getting a charge (or better said an avoided discharge) equivalent to 4 miles means 50 eurocent ($ 0,70) saved each day so even if the roof cost € 500 ($ 700) it would pay itself off in less than 3 years AND, most importantly, I would get to forever enjoy getting into a cool/warm car…

    As a matter of fact, provided it didn’t cost more than € 700-800 (around $ 1000) I would buy it even if I wouldn’t save any money at all, just to enjoy the added comfort with no further expenses other than the initial cost (i.e. no electricity/gasoline to run it).

    #34 Cautious Fan – “All the safety features you mentioned are theoretically available in an EREV without a PV roof. They run off the battery. And I haven’t read the PV will power the AC, only a small circulation fan.”

    I was looking at Lutz’s statement that the roof “could function keep the A/C on when parked on hot summer days.” However, thinking about it, I think your assumption about the roof being too small to run the AC is correct. Unless it’s supplemented by the battery or there is some nifty AC unit, which is possible. I’d say you’re almost certainly correct that a PV panel on a car roof is not a cost effective way to produce electricity. That’s not surprising if for no other reason than solar is not a cost effective way to produce electricity period (rebates change that but those are incentives). It could of course save gas but a flat roof which is not necessarily well positioned in relation to the sun is problematic.

    Having said that, if all it does is run a fan I’d probably get it anyway since from a safety standpoint it would still save lives. But that may just be my going overboard with safety features.

    Don’t forget, this is just the start. Every year the solar efficiency will get better and the cost will come down. Soon, it might be standard on many EVs and plug-in hybrids.

    Oh, I like the idea of different packages! There could be the ECO package that includes the solar panel as well as always-on Internet connection and interior cooling control. You can use your phone to call up to tell your Volt to start cooling. There could also be the extended security package that includes the solar panel as well as an enhanced security system that can send alerts to the driver if there is a problem with the car or possibly a theft. The possibilities are endless. Not to mention it could be an even stronger statement of your “greenness”. People see that beautiful solar roof and know you are the man. The green man. Eco man. lol.

    Fair point on the cost. If you drive less than 40 / day, use electricity costs. If more use gasoline costs of around $0.40 (U.S. gas). Static posted some better information on the cost of a PV roof. My $500 guess I just pulled out to show how uneconomical it is. #56 Static estimates the cost to be closer to $4,000 and that “feels” right to me. So asuming worst case commute (>40 miles), best case weather (100% sunshine), and a dirt cheap $2,500 option, that takes 17 years to pay off. Your 3 year estimate differs from this one because you use more expensive gas and a far cheaper roof.

    Nothing is stopping GM from running a cooling fan off the battery. With no PV you could still climb into a cool car.

    I agree with you about the small fan idea. To me this seems like a no-brainer application. It is relatively cheap…and more importantly also alow drain measure to keep the interior car temperature relatively ambient to the outside temperature.

    I’m not sure what the draw on the battery would be to keep the temperate even a few degrees cooler inside the car than outside. Considering that you needed a sealed environment to achieve this and you are also battling escalating interior temperatures on a hot/sunny day. But I’m guessing it would be pretty huge releatively speaking.

    ie) What is the draw to cool a car to 90 degrees inside, when it is 100 degrees and sunny outside?

    I have always agreed with you and this line of reasoning 100%. With that said I will buy the PV option unless I am priced out of it. I live in the high desert and park my car in an uncovered lot at work. I climbed in one day this summer, tried not to touch anything and burned my hand painfully just shifting. Also I have a two year old son and if I was to step out of the car and close the door and get into an argument with someone like Tagamet or static, then knowing the car would stay cool even if I didn’t would be priceless. Cost curves macro or micro, can be affected by emotions.

    PV roof is an option which I will look at like any other “cool” option (leather seats, fog lights, fancy rims/wheels etc.). Since I live in AZ I would appreciate the feature of keeping the car cooler (less hot) while it sits but the main consideration is whether it adds significantly to the looks…it may just look darn cool (it does in the Fisker pix)…..and then like any option it comes down to the price.

    The idea of an expensive credit card type charger is out of the question for most places and I doubt could be justified economically – I mean, do you really want to spend thousands of dollars to
    avoid someone stealing 50 cents worth of power, if that much?
    Most condos already have security parking areas – I simply can’t believe that an “electricity crook” would park his car, which obviously doesn’t belong there, in one spot for hours, at the risk of getting towed, in order to get a few cents worth of juice. My old condo is simply getting ready to install outlets at several open locations. Any
    charges would be paid at the front desk. Nothing fancy. My old condo pays around 6.5 cents per kilowatthour. At a 2 kilowatt draw
    rate that amounts to a big $3 per day if the outlet is used
    continuously 24 hours per day. The condo’s yearly budget exceeds $1 million dollars. I don’t see any reason for charging anybody anything. Not at this point.
    As more people buy plug-ins, then outlets will be installed at individual spaces, and people will have to pay.
    Hey, folks, it’s not as though suddenly tomorrow everyone is going
    to show up driving a plug-in.

    Not getting burned is a fair reason. So is making a statement. Regarding safety, nothing would stop GM from running a fan from battery power either though. PV isn’t required for this, though I suspect if you hit the battery depletion point the fan would turn off.

    And likewise Scossa. I think it’s important to consider alternatives and costs, and not just support something because it has a buzzword in it. Until we know the cost, the answer has a lot of uncertainty in it.

    I don’t know if it is possible for GM to save cash, pre-bankruptcy.

    But spending, borrowing and stealing as much captial as you can before you go Chapter 11, then turning around and ‘blowing it all,’ knowing you won’t be repaying it, to produce future infrastructures, complete expensive R&D, complete future production lines and get cost efficiencies down before you go bankrupt is kind of the same thing…and is exactly what I believe GM is doing right now with Volt and the entire flex line programs.

    Unfortunately with this type of plan the order of the day out of the executives mouths is alot of BS. Which although, it is the right thing to do for them fiscally, it drives me insane…especially when you see people investing in the company, or the gov’t/banks giving them money they have no intention to repay.

    If you go to work and leave the car parked outside all day without a plug, there’s no way to avoid it. The startup process will run the engine for a little bit.

    Of course, range itself will be reduced, simply from the need to run the electric heater to keep you warm while driving.

    I don’t think you can equate a house Solar system with a car’s on-board Solar system at any point, statik.

    Your house system is most likely based on silicon wafers which are very expensive and fragile. In order to put them on your roof, it was necessary to fully enclose them, front and back, and protect them from the weather with a transparent cover. The enclosure had to be strong enough to handle wind and snow loads (to say nothing of keeping the cells dry in a rainstorm, and as for hail … it doesn’t bear thinking about).

    The roof most likely to go on the Volt will be based on thin film; inefficient by comparison but much cheaper, and much more rugged. Vibration which could damage a crystal wouldn’t faze a film-based cell; and in fact, the whole array would amount to little more than a series of coatings over an existing body part.

    Further, the case for solar on a house vs a car is a completely different one. You have to very carefully cost out the installation over it’s lifetime, taking into account where and how it is specifically sited; and figure in the exchange rate of your electric utility. On a car, location and use begin to supercede such considerations.

    In my area we have “School Speed Limit [X]mph When Flashing” signs which are powered by solar arrays. In many cases, these signs sit under a conventional power line. The cost of the electricity must be much higher for the sign coming from the solar array than it would be from the grid. However, it must be that so much money is saved by not having a buried line to go up a pole to a meter and transformer that it becomes a no-brainer (every new such installation I’ve seen for the past year uses these signs).

    The fact that the array is on a car verses a house changes virtually everything about Solar. The added value of safety, range and mobility add a value which is much more difficult to calculate, using a technology which itself is drastically different.

    NOTE: CIGS cells are more efficient and costly than thin films, but share many of the advantages (any shape, more rugged etc), and I predict this would be the next step beyond thin film.

    ——————————————————-

    Um, I’m not sure, but what is your point to me? I think maybe you are arguing something you perceive to be in my posts, but aren’t really there.

    A) by solar housing experience in relation to the Volt
    B) the raw cost of solar collectors

    I prefaced my ‘math’ on solar costing in #56 by saying:

    “Well I have a PV system, costing is not really something I can reasonably do from my residential experience,” then I continued into my guesstimating just based on expected auto-business related issues.

    Besides that, and what seems to be the bulk of your post, I didn’t stipulate at ANY point that the cells themselves were anywhere near the problem when getting to the cost.

    It is all the rest of the stuff, the hardware as a whole, the wiring, the inverter, the integration, the product lab testing to make sure the application works, the paying human beings $25/hour to do the conversion, etc., etc.

    A 60 watt Kaneka panel ‘old school’ (which is actually amorphous) is $180 bucks, we only need about 90 watts, thats $270 in raw panelling cost. I don’t care if your thin film is free, this is such a small application, that portion of the cost it is near irrelevant.

    I already said that it was ‘cool,’ and is better than/offers alot more than oother options, but from a monetary standpoint only… it makes no sense.

    ECD is a good guess. Another Ovshinshy technology. GM had a good relationship with him on the development of the related NiMH technologies for the EV-1. That may have gone downhill somewhat after they sold that joint venture to Chevron… which pretty much destroyed it through strangling Cobasys.

    Still the ECD material has some advantages for cars. It’s not brittle, and can conform to a curved rooftop. It’s not terribly expensive. It doesn’t have a high power output, but it does support its lower power output in more types of lighting conditions. (eg, it doesn’t produce as high a power as silicon in bright sunlight, but produces more in low light, relatively).

    I would totally consider a solar roof option to keep the car cool. Depends on how much it costs for that luxury. By the time the \Volt is released I’ll be more worried about my kids trying to climb out of the car than getting stuck in it so it’ll definitely be a luxury by then for me. :)

    Much better than just having an otherwise functionally useless black roof to otherwise melt the interior of your car. I’m not too happy with \Volt’s black roof styling thing. Might look cool but cool it isn’t! :)

    In both traditional vehicles and FULL hybrids, this is accomplished by running both the Heater and A/C at the same time. If Volt only has a single system available, how will it condition the winter air to deal with both cold & moisture?

    Since the government has taken over the entire US economy they should solve the cheap oil dilemma by banning the commercial import of any foreign oil. Oil companies that need crude for US refineries would be required to purchase it from the US government which will acquire it as needed on the world markets. Offshore US crude would be similarly controlled by the States, giving them rebates for income.
    The US govt would then set the US market price for crude, supporting the price to perhaps at least $2.00/gal of gasoline and etc for other oil products. Hopefully the govt could manage to make a small middleman profit when world crude prices are high(just pass it through) and make a windfall when world crude prices fall to more economic levels.
    These revenues could support US produced electric cars, US production of batteries, nuclear power, clean coal, and the development of shale to ethanol or something else good to drink.

    So, probably $4,000-$5,000 to the consumer? Does that sound right?”

    $1500 doesn’t sound like $180 in terms of hardware. I can’t comment on integration testing etc, though the thin film / CIGS approach strikes me as needing much less physical integration than inflexible wafers; but shouldn’t that sort of research be spread over the total number of cars?

    But then you say

    “They charge $800 just to put a hole in a Malibu.”

    If you honestly think that GM is going to price a thin-film solar array at $4000 – $5000, then the most outspoken GM detractors are correct: GM is just looking for the most plausible way to screw the consumer.

    Actually, my logic for the PV system wouldn’t be an investment return, it would be more for my personal security. While battery conditioning and parking lot issues abound, I really want it for the emergency charge it can give me when I have no gas OR power available. If I have to make an emergency run to the hospital in the aftermath of a hurricane that knocks power out for two weeks, the PV will supply everything I need, seeing as I certainly wouldn’t be going to work that week (judging by last time…). In the meantime, I can plug into the car’s lighter or whatever it has and tap some of that solar power and the giant battery to keep my cell operating in the interim. I use a similar system at my house now and it’s great. Charging isn’t fast from 80 watts, but with three deep cycles it runs the freezer and everything during storms. I can only imagine that the Volt will have better efficiency and is a heck of a lot easier to move.

    I hate when Lutz says he wants the genset to warm the batteries. That’s the most stupid solution. The car is going to be plugged in at night anyway, this gives the car all the power it needs to heat the battery pack using electricity prior to unplugging and driving off.

    Lutz has been the most unreliable source for Volt information since the beginning. Let’s hope this is just more of the same.

    If GM declares bankruptcy, it might be because of a strategic move not an act of desperation. It could allow them to make a faster turn with a ship that is/was headed towards the rocks.

    I believe now is a good time to buy blue chip stocks. I just bought into GE since Warren Buffet did, and after today’s drop I might be moving more into GM. If they go to bankruptcy, then I might consider some of their bonds. I’m utilizing a roth IRA account for these 2, I’m planning/hoping to hold them long term.

    Your absolutely right. I will not buy a Volt until it makes economic sense. But I have faith that it will come. I think the Volt technology is a game changer, but it will take time. So I’m not holding mutually exculsive positions when I root for the Volt while at the same time attempting to make rational economic decisions.

    If you want a PV panel, by all means purchase one. Heaven knows GM could use the extra profits and I don’t have any axe to grind with PV. I think GM is smart to offer this as an extra to extract more profit out of their customers.

    Question for Statik: When GM is broken apart after a Cerberus-type company buys it up fire-sale in the next few weeks, who will buy up the Volt program?

    Toyota comes to mind…but Honda has more money. Of course, a Cerberus-type group would need to borrow money to do this and, well, that ain’t easy right now.

    PS I wouldn’t invest in Honda right now…they just haven’t fallen YET.

    Solar Venting IS extremely practicable for the Volt. Here in the South, interior temps are 40 to 60 degrees hotter if the vehicle isn’t vented.
    The interior of the Volt is projected to use “low thermal intertia” materials.
    This means that the materials will readily give up their lower accumulated btu ’s of heat. Solar venting will greatly save on the Air Conditioning initial wattage ramp-up demand.
    Other neat things can be designed with electric Air Conditioning. For example, when near quitting time, you might be able to press your “lock”button twice in your office, and your remote key fob module might be programmable to start cooling down your Volt, so that 60 seconds later, you get into a cool vehicle. This may have a synergistic effect in that the initially higher wattage demand of the AC would be slightly lowered by the same time that electric propulsion occurs. The traction battery may need to produce a slightly lowered peak demand.

    OK, if we assume the mid-point of 1/4 to 1/3, this would be 28.6%.

    At 4 miles per 5% of charge (from 40 miles consuming 50% of charge), this works out to 23 miles of additional range per three days sitting outside in the sun, or 7.6 miles per day.

    If I’m living in the south (where there is lots of solar energy), driving 47.5 miles per day, assuming 30 mpg/$4 gallon once the ICE kicks in, then a $200 PV roof will pay for itself in about 200 days.

    You’re right about power requirements though, with a 16kv battery and the distances I drive, I really don’t need PV but I’m convinced that GM doesn’t want to take the chance running the AC without a PV charge would create problems.

    Usually a fan would be a great idea for safety. However, inside the Volt greenhouse with direct desert summer sun and temps in the shade at 115, I think that my family would bake only just a little slower and under convection conditions.

    D’Artagnon #147

    What if the PV option is closer to a grand in price and because of the inclination of the suns rays vs. the panel laying flat on the car you actually only get an added mile or two each day and only in direct paint and interior damaging sun?

    Putting a PV system at your home, optimized for solar conditions in your area, will run your meter backwards at much higher efficiencies. It will do this when you are at work, when you are plugged in, when the car is garaged etc.Even when you are parked in shade or under covered parking or its cloudy and the suns angle is too low to affect the ad hoc angle PV array on your car. Money put into a PV array at home will always be more effectively spent.

    PV on a house takes it about 3 years until you are net energy positive. With incentives here in California it has typically taken about 15 to 18 years to recoup the initial investment, disregarding the time value of funds.

    I don’t see the need for the ’sliding door’ to prevent thieves from stealing power. And, that ’sliding door’ is prone to malfunctions and many other problem situations.

    A far simpler idea would be to dispense electricity after the plug is inserted AND a credit card is swipped, in that order. It stops dispensing electricity when the battery is charged OR it is unplugged, whichever comes first. It will not dispense electricity again until the process is started all over again.

    Or, am I missing something here?

    One of the great advantages that GM has when designing from “a clean sheet of paper”, is that the various types of energy can be redirected to do very helpful things instead of being thrown away.
    The ICE throws away 80 to 90 percent of the heat produced from combustion out the exhaust, cooling system, and block.
    However, perhaps with the Volt, after the exhaust (from the Generator-Range Extender) leaves a Catalyst, it can be sent into a heat exchanger to quickly heat the vehicle and batteries. The idea is to protect the batteries from low temperature discharge-damage, such as when parking outside in very frigid temps when parking anywhere no outlets would be available.
    I’m an independent trainer of Advanced (ICE) techs. One thing I can tell you is this:
    In designing the hundreds of different automotive software systems to faultlessness, one thing you can bet on, is that GM’s decades of highly practicable designs by armies of engineers of the highest talent are doing incredible things.
    I know this because GM is the very best at helping the independent technician with the most complete array of diagnostic datastreams (Parameter ID’s) with which technicians can far more easily diagnose systems needs.
    I’ll bet that the Volt’s PIDs will be the route by which we will all learn about electric propulsion, and the technological changeover coming very, very soon..
    The Toyota Prius also has exceptional PIDs in its “Hybrid Vehicle
    Battery” PID subgroup, which tell us everything we need to know about each battery block.(1-14).
    I hope ALL plug-in manufacturers openly release all PID’s
    and not “sequester” (not show) (as I call it) any datastream items for Plug-ins.
    Hopefully, GM’s industry-standard in allowing far morel PIDs to be viewed and studied will also be the case for all other makes.
    I do not believe that doing so would be opening any “Pandora’s box”, especially since that each high voltage component would be more readily seen as still at a high voltage state, and thus, a highly appropriate and necessary set of warnings.
    The reason why I need to know this is that if you lend-out your plug-in, and someone abuses it to a very nasty extent, then there ought to be a date-time stamp for the freeze-frame (a set of fixed data items that tell us how badly something happened) in order to help tag the responsibility to where it belongs. That way, GM should not :have to “hear It”, and, new designs can be given a far better chance to retain their reputations. Processors can and do very easily discern these things.
    Warning the abuser by flashing a “Systems Abuse Logged” MIL (and a reeeeeely loud buzzer) might deter extended abusiveness, and protect the owners vehicle from the “Lead-Foot” mindset prevalent today.

    Does this photovoltic roof mean there is no chance for a convertible Volt?
