GM’s Advanced Battery Director on Why LG Chem Beat A123 for the Chevy Volt Contract

 

Those of us who follow the Volt story closely have known for a long time that LG Chem and A123 were in competition to get the Chevy Volt battery contract. Earlier this month, GM announced it had chosen LG Chem. I had the chance to ask Denise Gray, who is GM’S Direct of Advanced Batteries how and why the decision was made.

So why did you choose LG Chem over A123?

There was a number of reasons that went into the decision-making process, not one single element.
From a longevity of being in the battery business, design readiness, and a design that integrated into our battery pack design. There’s a lot of work to make sure that the size of the cells are appropriate for structural integrity or the cooling system that we designed to go into that, and for the electronic system, all the monitoring, for the high voltage carrying capacity, just for the overall height of the cells to fit into the vehicles so that all of our rear-impact and side impact tests are passed.

So you’re saying it was more the integration of the cells into the pack design that played a role than the actual chemistry?
All of the above, the chemistry and the capability, LG’s manufacturability, and the work that they’ve done and the lines that are in place today from a prototype perspective. The integration of the size of that cell equivalent to our overall scheme.

The different chemistries have different thermal characteristics and so we’ve been able to incorporate how to make sure from a thermal perspective that we’ve got it, from a functional perspective, not a safety perspective.

So it was all of those. Experience, manufacturing, and performance.

Did they win by a landslide or was it a close race?
I’d say it was a close race.

I heard you guys were from early on only using LG packs in the mules?
Both packs were in our laboratory undergoing tests. Both from the mounting capability, the shape of them all looked the same so we could put in one or the other (in the mules). LG had the lion’s share of our mule testing, because they had them available earlier.

So they were able to get you more packs sooner?
That’s right. It really wasn’t because one was better than the other at that time, it was all those things I mentioned coming together as well as the availability of the packs.

    Good to hear things have settled with the choice of battery.

    The electric car I drive has a real nice launch feeling up to about 20 mph. I would like to hear more on the passing power of the Voltec System. Also, will there be some sort of lower/higher gearing? Or just a smooth feel though the entire available power curve.

    Rather than having a “sport” mode. Why not just add a switch to the fully depressed “gas” pedal? Sort of like a 4 barrel carb or turbo kicking in.

    I’m going with you…and the part about ‘LG’s manufacturability,’ I read as they are a bigger, more stable company that we don’t think we are going to have a issue with later.

    There is a lot of talk implying that ‘functionality’ and the ’size of the cells’ being the main reason, but c’mon….I can’t buy that as reason number one to choose LG Chem (maybe convenient excuse number 1). Why have a year long battery competition, then another 6 month delay, if you know A123 cells aren’t physically going to work for you?

    All that being said, GM probably made the right choice going with the ‘proven player,’ they are not in a situation where they can afford any more hiccups.

    It sounds like A123 is no worse for wear, and has a lot of other things on the go now with some of the other 27 companies planning to build a EV in 2010…I have a feeling that when they have a track record they will do some business with GM.

    Yes. Big companies like to do business with big companies. LG has annual sales around $100 billion. This is probably the main reason GM chose LG.

    I’m glad. I would much rather have my battery cells manufactured in South Korea than China.

    As I understand it, a battery cell manufacturing plant is a fairly big deal. It takes a long time to get the cell manufacturing up and running efficiently at large volumes. Much more difficult than building a battery pack integration plant.

    So the reality is that A123’s cells will continue being produced in China for several years.

    GM has said they will consider A123 in the future, but for the 2011 model year Volt, it’s a done deal – LG is the supplier.

    Absolutely, what you guys said and I’ld add existing manufacturing capacity (which Statik alludes to as well). I don’t know about experience from a chemistry perspective. I think there may be longer real world application of A123’s chemistry. Perhaps GM was scared off by A123’s legal issues too. Aren’t they being sued?

    I’m with GM’s advanced technology team and I agree with Van…sometimes people read too much into decisions we make and make them more complicated than they need to be. We source components from across the globe and LG Chem was chosen because of their performance, production readiness, vehicle integration, efficiency and durability.

    We’ve been testing their cells for more than a year and we’re confident they will meet the performance and durability requirements of the Volt. Plus, they demonstrated the manufacturing readiness for prismatic cells to meet our program timing.

    Plus, many people are overlooking the fact we will be manufacturing the battery packs right here in the U.S. in Michigan. That is no small feat. The cell is only one component of the pack. And we will continue to work with A123Systems because we have many needs that need to be met with our hybrid and extended range electric vehicles.

    #16 Dave G & #18 Tagamet commenting on the CARB issue.

    CARB is requiring companies who do modifications to hybrids to test one car in order to prove that their modification doesn’t screw up the existing pollution control systems. It will cost about $1500 – $3000 for the test. CARB also requires companies doing the modifications to cover the warranty if their modification voids the manufacturer’s warranty (that’s been around for a while).

    This got turned into one of those internet rumors that CARB was driving the companies out of business by making them pay hundreds of thousands of dollars, apparently misinterpreting the requirement to test one modified car as a requirement to test every modified car.

    Thanks. Nice concise useful explanation. Yes, manufacturing the battery pack is a very big deal.

    Also let’s note that GM has an ownership stake in A123. It’s not like they don’t want A123 to succeed.

    As for price, BYD has announced it will sell battery packs to NA manufacturers at about half the price as existing packs are going for. If true that would be a big deal.

The warranty issue could pose a problem though as a theoretical matter it seems fair and as a practical matter it’s not likely to be an issue.

    Could be a lot of people are confused. But it will no doubt get sorted!

I also know Denise Gray, Bob Kruse, Tony Posawatz and many others involved in battery and Volt development. I would definitely question Ben Roethlisberger posting on here too since he is probably a little busy right now, but I think the real question is, are you really in PA, Jim? ;-)

    And, one more quick note for clarification purposes, GM does not have an ownership stake in A123Systems.

    Does having a dangerous rogue state like North Korea next door have any implications on battery supply from only from South Korea? They have a huge standing army and an on-again off-again nuke development program. Also have a long standing desire for South Korean real estate. And right now they probably perceive Obama as much weaker than Bush was.

    Now new war in Korea might mean no Volts in USA.

    It would be nice to have multiple battery sources as soon as possible.

    That sounds right…
    “it was all those things I mentioned coming together as well as the availability of the packs.”

    I worked in manufacturing, not in the auto industry, and it was almost always who made it to the prototype bench test first. AND, how much of the “Schmoooozing” factor came along with it. Trust me, It does happen.

    Now, I know A123 has a great product and I believe the Nanophosphate tech is better. Since A123 did not get it, they can actually build a “Compatible” battery pack and sell it for a third party battery and compete in the battery market with it. They already have the dimensions and spec’s that are needed, just tweak the specs and dimensions so not to violate “Proprietary Knowledge”. Competition is always good.

    I’m not as bothered about importing the cells for now. We need to get the ball rolling. If Volt sales start to ramp up, and other manufacturers follow suit, then there will be more incentive for the U.S. to build battery cell manufacturing plants.

    I feel the same about ethanol. We can use imported ethanol from Brazil to help jump-start our market. Once FlexFuel cars and E85 filling stations become commonplace, there will be more incentive for the U.S. to start producing cellulosic ethanol.

    So, ironically, I think the best way to bring green energy jobs to the U.S. is to jump-start the green energy markets in any way possible, including imports.

    Not sure if this is the right or wrong place to post this question about batteries. If the cost of the batteries is so high what about a Volt-like car that does not have the batteries? If the car gets 50mpg running the engine/generator offer a Gas Powered Electric (GPE) vehicle or better yet a Diesel Powered Electric (DPE) that would get 80+ mpg. The car would still be “electric” driven and still be better than anything else out there. Without the cost, weight and cold/hot battery issues that come with the large battery component. It would be a lower cost model. Just a thought…..

    I wonder if GM ever explored the idea of “Batteries not included?”. Then they could price the car at $15K-$20K and not warranty the battery. All the battery companies would be given specs to build to, and the buyer would have the option of buying from whomever he/she wanted to…. just an idea.

    In response to #37, there were some articles from Bob Lutz addressing that. In short, he said the idea was to have a car that runs w/out using gas. So to have one that required filling all the time, was not the goal. There are also engineering issues about storing energy, acceleration, rpm efficiency.

    #10 Dave,

    I wonder where you got the figure 95 – 98 % efficient electric motor. In my google search for motors, The efficiency depends on the type of electric motor. Ex: stepper is made for more accurate control where efficiency is very low. where as brush less DC motors are better but i was not able to get the % of efficiency.

    Wondering what kind of motor GM uses as efficiency of the motor is also key is range and life of motor.

    #37 ,
    In my expectations

    ICE engine ( max efficiency 32% ) ==== Battery ( assume no losses) == Electric motor ( lets say 95% efficient )
    should be same as 30 percent efficient ICE engine ( study says average ice engine efficiency in US driving is 20 % ) and optimization of power distribution on different driving conditions by software should give Volt an extended range mode mpg of 70 – 90+ mpg on road.

    A123 is still in the game for supplying future batteries to not only GM but to Ford, Chrysler and others. They just were not “ready” for the Volt version 1. Later on, GM and A123 will do some business, I feel sure. There will be enough of demand and diversity of cars and trucks needing battery cells that one company can not handle all the orders, I would think.

    I agree w/ Dave G on that.

    South Korea is more Quality Control orientated compared to China with regards to manufacturing. I find the China QC issue interesting in that China has a serious QC conundrum: The degree to which a government both centrally controls a national manufacturing base (other than setting minimum industry quality levels) and also centrally controls citizen’s personal lives is inversely correlated to QC levels. Another way to say it is that high QC levels require individual citizen initiative/pride/heart/resolve/ownership and China’s centralized political culture is designed towards diminishing each of those individual attributes. This QC dynamic is something for America to be mindful of as we march down the path of nationalizing large segments of American remaining private industry (autos, banks, insurance, health care, etc…).

    Missed in my previous comment : max efficiency of ice engine normal is 37 percent and not 32.

    Boils down to expectations of extended range mpg after all the losses on extended range should be minimum to 90mpg+.

    means with volt should give 90 + 40 + 5 miles with a fully charged battery and a gallon of gas in normal road test ( 5 for regenerative breaks/shocks ).

    This is the minimum numbers in theory to expect with this much research,test and hype .

    If all you are after is higher mileage it can be gained with out using a Volt with out a battery. The Cruze is one example. I know your question was for a Volt to have a generator ICE that supplied electricity to the electric motor that turned the wheels. I can see that as a possibility, but probably not a desirable one. The battery helps to supply additional power when operating in ICE mode when the car needs extra power up hills or passing, etc. Theoretically your Volt with out the battery would work, but would be a pretty ho-hum car. IMO.

    In reference to the above picture, I could see GM selling just such a “car” shell to other manufacturers who would add their own body and other components. That would be an interesting spin-off of the Volt development process. The above picture has all the working parts of the power train, the battery and the software to control everything. All another company would have to do is to just finish the shell, the interior and add tires, etc. What do you think, GM?

    ————————————————————————————–
    The Volt uses a 120kw (160 hp) AC induction electric motor. I believe the efficiency of this motor is somewhere between 90-95%.

    All of today’s hybrids use brushless motors. Cars that use induction motors include the EV-1, the Tesla Roadster, the tzero, and the Volt.

    The main advantage of induction is that it scales better for higher power applications. The downside of induction is that the software for the motor controller it is much more complicated than with brushless motors.

    Induction motors use wire windings on the rotor, whereas brushless motors use permanent magnets on the rotor. More info here:

    Beside, the most likely conflict in East Asia right now is between China Vs Japan vs Korea over sea territories, and all three sides massively beefing up their naval and air power to prepare for possible naval confrontations. The fact that these territorial wars would be fought in the sea over small islands instead of their mainlands make the wars far more likely. As of now, the most likely war in East Asia is the naval war between Japan and Korea, not Kim Jong Il’s war.

    This question has been asked and answered many times before.

    The Volt won’t work without a fairly large battery. The Volt get’s high milage by using a very low power gas engine. This engine only provides AVERAGE horsepower. PEAK horsepower is still provided by the batteries, even after the gas engine turns on.

    If you removed the battery from the Volt, it would be such a dog that nobody would buy it. Think 0-60 in like 30 seconds. It would be unusable in the real world.

    Dave G @ 34,

    Once FlexFuel cars and E85 filling stations become commonplace, there will be more incentive for the U.S. to start producing cellulosic ethanol.

    It depends on where you live. E85 vehicles are already commonplace (look for the leaf logo on non-hybrid Ford vehicles, and similar logos on newer GM vehicles). They’re common enough I almost bought a used E85-compatible Ford Ranger in 2003, but I opted for a cheaper gasoline-only Ranger from a more reputable dealer… Also, if you live in the Midwest, E85 stations are scattered throughout.

    But it depends where you live — when I lived in Virginia, I never saw an E85 station, despite a couple of road-trips through the midwest. The fuel-finder on http://www.mapquest.com can search for E85 stations.

    Sorry to inform you that what you suggest is already here (and has been for years), but it doesn’t seem to be jump-starting cellulosic ethanol just yet. I sure hope it does, and the snippets that I’ve heard about a cellulosic ethanol pilot plant or two have been encouraging. But, really, the reason ethanol is so common in the Midwest is because increased demand for corn is good for local economy — and the politicians and voters know it. I’m hopeful that the cellulosic ethanol catches on, though — it just sounds like such a Good Idea!

    Anyway, I just wanted to complicate your day — have a good one! :-)

    I wouldn’t be surprised if A123 got the contract for battery cells for the Converj or “new and improved” battery cells for future Volts in 2013+. A123 is a much smaller company than LG Chem. They need to get super organized and get a track record of high quality automotive battery cells coming out of their plants. A year of rock solid production would probably make GM more confident about going with A123. A123 also has to meet all of GM specifications too. GM wants those flat “prismatic” cells that are easier to keep cool and assemble into the packs, etc.

    I’m with you there bro. If they can just plop the Volt battery and engine on the “Spark” you’ll have a little commuter hooptie with a SWAG min range of 60mpc and a quick 0-60 for the small lightweight of the Spark. Now that’ll cause a spark huh?

    I think Ford will beat most mfgrs to the BEV market with their Blue Oval Focus BEV that Lyle got to drive. They went down the road of “Retrofitting” an existing chassis, not from a ground up build. It was cheaper than engineering and “Time to prototype” was about less than a year. That’s the version Lyle drove, I think it was the production intent also. It looks like their “Time To Market” is for a 2011 rollout,

I do not want to see any one buying Chinese if there is a second choice. Damn right, I’ll pay a higher price for the opportunity to buy from a non-Chinese source.

They have “future” car madness and can only think in those terms. There is no reason why an existing model could not be converted without the worry of aerodynamics since we are not asking for a hyper mileage car. The “Spark” concept is designed well enough aerodynamically to achieve high miles per charge, I would think. If THINK can produce a vehicle that gets good MPC with the shape of their vehicle, just think what the “Spark” should do. But, GM has their attention somewhere else and I don’t see them seeing the bull that gores them.

    I can’t imagine that the Volt T pack can fit in a Spark and still have the car pass collision tests. The Cruze/Volt genset engine would likely be overkill for such a small car. And this ignores the weight implications …

    That’s not to say that there won’t be an EREV Spark (or something like it), just not until GM feels comfortable enough to modularize the Volt batteries into sub-units of the “T,” probably at around the same time as the power density improves. Say, 2013 at the earliest?

    I have the distinct impression that GM has found a “sweet spot” it intends to stick with; mid-size 40 mile AER automobiles: perhaps at the risk of abandoning of a more popular segment (and perhaps not).

    Eventually, I suspect that several companies will have full-ranges of electric vehicle types and sizes, but the smart ones will start by concentrating on just one paradigm.

    When I suggested using the “Spark” concept as GM’s entry into the small electric vehicle market, I was not suggesting using it as an E-REV type vehicle but as a BEV. I am not suggesting using the T-shaped battery in the Volt as the electric Spark’s battery. Surely GM can design a battery for an ALL ELECTRIC VEHICLE that is not T-shaped. If not, then to the dust heap of history goes GM. But, not to worry, of course they can design a different shaped battery. I am just suggesting GM get into the BEV market with something that gets good MPC.

    As far as LG Chem having an exclusive contract lasting through 2015, I suspect that is only for the Volt. If GM brings out the Cadillac Converj, I don’t think LG Chem will have any exclusive contract and will have to “win” the contract just like any other battery manufacturer. They would have the “inside track”, of course. The same would go for an all electric car or truck (BEV) GM might decide to make.

    Some of us are naturally willing to sell our bodies and souls to save a few pennies at the local WalMart. I am not. I stand on principle where there is a place to stand. Those places to stand are being eroded daily by our government and industries. I know we all want superior products at the lowest possible price, but that is exactly what leads to our losing American manufacturing jobs and industries going overseas for everything from pickles to pickaxes. I don’t agree with those that say we must buy from China, India or other foreign suppliers for everything we want in this world. At the very least we can chose to buy from suppliers that are somewhat friendly with us.

    And, yes, we are funding China’s military. The Chinese military owns many of China’s factories. Sure China is becoming more capitalistic, but only in markets where they need to do so to compete.

    I just don’t believe everyone is going to jump on board with China supplying all the electric cars for the world. Japan will make them, Korea will make them and maybe, just maybe the good Ole U. S. of A. will supply some also. As long as I have a choice I chose to not buy Chinese products. That’s just me. You other people do what you like.

    Since you asked, GM is the clear leader when it comes to biofuels, specifically ethanol. We have more than 3.5 million flex-fuel vehicles on the road and have committed to half our fleet being flex-fuel capable by 2012, including the Volt which will be flex-fuel at launch. We have also invested in two of the more promising cellulosic ethanol start-ups, Coskata and Mascoma. And there are many who agree with you a combination of E-REV with flex-fuel, especially if the flex-fuel is cellulosic ethanol, is an unbeatable combo. Btw, there are more than 7 million flex-fuel vehicles on the road across all manufacturers. And to be clear, no one is saying ethanol is THE solution, but it’s definitely part of the solution.

    #50 N Riley and others:

    Honestly, there are a whole host of reasons against those kind of scenarios, not the least of which are vehicle safety and complexity of the integration. Vehicles are not a plug-and-play type of product, and when you’re talking about the heart and soul of the vehicle, i.e., the battery, you have to have rigorous testing in place to ensure the vehicle will be up to snuff. For example, we’ve tested the Volt battery packs 24-7 in a controlled environment for more than a year, while also testing the packs in cars on the road. This testing will continue right up until start of production.

    And as far as selling off the Voltec system with its chassis for other manufacturers to finish off the product, it’s probably not in our best interest. That’s not to say as future generations of the system evolve it wouldn’t happen, but we have a clear competitive advantage with the system and need to protect it for the long term.

    I recommend an ” I ” shape. OK the top of the I doesn’t show up but I think you get the jist. Battery along both axles and through the center of the car. This should give at least 10 more mpc and the smaller vehicle and weight should give it another 10mpc. This will work for me.
    I think GM can do it but if History reveals itself, it will be deemed “Marginally Profitable” and they won’t even take a second look at it.
    That’s why they are working so hard on the Converj or whatever it was called. They said they can sell it for more at a higher profit margin.

    And I do not see GM allowing others to make batteries beyond just cells for them. I don’t think they will ever allow someone to make a “battery pack” that is plug & play with the Volt or other GM vehicle. GM would have to give out too much info on pack controls in hardware and software. I don’t see that happening anytime soon.

    Thanks for you input today. We are looking forward to more from you. We also know that you can only say so much with our getting into trouble (unless you have been given the green light by GM management to speak “on their behalf”). I assume you are just a typical GM employee who has something to say. We welcome your input.

    __________________________________

    That’s incorrect. There are several prototypes demonstrating it, most notably the FCHV. Much smaller battery-capacity than “40 miles” is quite realistic.

    Reduced size would make Volt competitive, but we know how certain people have campaigned heavily in support of the “40 mile” marketing and are now stuck with it.

    Of course, little proof is needed anyway. Operation in Volt’s depleted-mode confirms that.

    My impressions from having lived there is that I think you can relax about the Chinese government having some sort of imperial ambitions. China is a very big place and it thinks of itself as being the center of the universe. The desire to militarily expand simply isn’t there. Of course it wants to protect its borders, and there is definitely nationalism, but it’s hardly like WWII Japan.

    That does not mean, however, that they don’t want to best us in trade. That’s a completely different issue.

    With reference to getting a Volt without a battery it would not get the miles per gallon because you need it for capturing the energy from regenerative breaking. You could probably get by with a battery a quarter of the size of the present one, even smaller if the cells were A123 as they take a charge faster without overheating due to their low resistance.

    As far as the Chinese military owning the manufacturing, maybe for tanks, but not for a lot of stuff, I know two people who buy products manufactured in China for resale in the US. Both will tell you the quality varies from crap to excellent. It is a matter of the design, and testing built into the contract. You can’t test quality into a product if the design is inadequate to start with, but you can inspect the product to insure the design requirements are adhered to and enforce it.

    With respect to the baby formula contaminated with plastic, many Chinese children were sickened, some died, and two, maybe three people will be executed because of their actions. I do not think that is any sort of America hating. I believe it was more like unregulated capitalism. I could only wish we would execute a few crooks in wall street that have wiped out peoples retirement, leading to many early deaths due to inadequate health care but it won’t happen.

    With the modularizing of the battery, GM ought to be able to make an “I,” a box, an “H” or whatever. For now, it’s just the “T,” and I think all we’ll see for awhile is the range of vehicles from GM that can be deployed with it.

    N. Riley,

    Personally, I prefer the EREV concept, though I wouldn’t say “No” to a higher AER. Frankly, I’ll be surprized to see a small BEV from GM, with so many others around the world apparently poised to pounce on this particular concept. I see no reason why a smaller car wouldn’t go just as far as the Volt, but only using an “I” battery in the 10-ish Mwh range, and 3-cylinder genset.

    My point is that, at first, we’re unlikely to see different kinds of electric vehicles from the same manufacturer. Someone will get an early “winner,” everyone will move to copy it, and only then will we start to see more complete lines, once real money is being made.

    The problem with cellulosic ethanol is not one of catching on. The problem is no one has developed a process for making ethanol out of cellulose on a large scale. Such a process may be possible, or it may not. No one knows.

    Funding for trying to find a process is very good public policy. But using the “promise” of cheap cellulosic ethanol as an excuse to fail to support nuclear power and electric cars is very bad policy.

    One of the neat things about being in business is that you can get to the point where you know a technical field so well, that, you can let time work for you. You can let any opposition go to work for you (to efficiently control unwanted excessive-growth before you have all your “ducks in a row” to thoroughly control your position of leadership in any feild). The impressive thing about GM, is that GM does this exceedingly well. You can let one battery chemistry (and supplier) be in an initial position to “prove their salt” in durability, delivery, cost, business long-term “follow-throughs” (as I call them), where what you promised a year or two ago, you have perfectly delivered, (which becomes your reputation).
    It’s really a lot of fun to see which companies do what in business, and to finally realize that they are either highly dedicated to their customers needs, or, that they are highly dedicated to shareholder needs as their highest priority. I think A123 is dedicated to the customer and the environment firstly. (Not to say LG is not.)
    But it really seems to me that you need not be the “first” to be the “best”.
    America demands jobs here in America. We will certainly keep that in mind if there comes available the choice in battery pack suppliers from GM (USA-Made, for example) at whatever differential cost as a commitment to helping take care of our own long lists of unemployed, if that choice means more jobs in North America, it seems to me.
    Understandably at first, there must be an extremely vast concert of production schedules which essentially number in the tens-of-thousands of direct and spin-off contracts to suppliers and the suppliers to those suppliers (and on, and on).
    But it is really a lot of fun to watch these pros.
    That means GM’s efficient acceleration of these projects.
    The open sharing of milestones and benchmarks is really entertaining as well as a profound set of business lessons in patience, dedication, relentless drive, and follow-through for all of us if we are able to view it all in these terms.
    America is back on the track to being the very best in technology, and it is General Motors Corp. which is getting us all there and re-affirming our technical heritages.

    30% of 16kwh is 4.8kwh. Thats about what you need in the battery when the engine is running. You need that to get up a steep mountain slope and still not drain down near zero. And 4.8kwh can’t be 100% charge, or the battery will wear out fast. You need a little buffer on top of that. So for the Volt to work without plugging in, you would probably need a battery around 6 to 7 kwh. That’s a fairly big battery, which was was my original point.

    ____________________________________

    In addition, the size of the battery must be significant enough to supply the peak horsepower. Bigger batteries not only have more energy storage (kWH) but also more instantaneous power (kW). So a little battery with a 5 or 10 mile range won’t cut it.

    Neither of your posts make sense. They seem to contradict each other too. Perhaps there is a misunderstanding or incorrect assumption based on lifetime overhead.

    Here’s a rough stack up that allows full electrics to be compared to all types of hybrid configurations, or all gassers for that matter.

    Assumptions:

    1 gallon retail gasoline = 33 kWh of energy, supported by several sources, and reasonable for current retail gas, which has 10% ethanol (less energy), NOT valid for diesel, which has more energy.

    Manufacturers claims taken at face value except where noted:

    The metric is number of kilowatt hours per 100 miles (# kWh / 100 miles). The smaller the number, the more efficient the vehicle. To directly compare vehicle efficiencies, divide the larger number by the smaller number – that’s how much more efficient the smaller number vehicle is compared to the larger number vehicle:

    Camry hybrid or Ford Escape hybrid
    mixed mode 98 kWh / 100 miles

    Prius (2004 to current version)
    gas only 98 kWh / 100 miles
    mixed mode 75 kWh / 100 miles
    all electric mode 52 kWh / 100 miles

    Chevy Volt (dubious number on weight issues – see Tesla)
    33 kWh / 100 miles

    2009 Tesla Roadster (NOT the Sport version)
    28 kWh / 100 miles

    2008 Zero X Motorcycle (kitted, average real world energy use over 7,000 mile)
    2 kWh / 100 miles

    An example: The 2008 Zero X motorcycle is 14 times more efficient than the 2009 Tesla Roadster (28 / 2 = 14).

    My numbers are based completely on the common gas energy assumption, on manufacturers claims and on manufacturer power pack specifications and likely power pack management regime to maximize total power pack life.

    Can anyone improve on this, until the EPA gets off their fat assess and does it properly?

    So far, it looks like series hybrids are WAY more efficient than parallel hybrid – why do you think diesel trains are set up that way. Electric drive wins again.e

    Series hybrids can be less efficient than Prius type hybrids, mostly at hwy speeds where the engine is directly driving the wheels with little help from the motors.. motors have to deal with many losses.

    #88 john1701a,

    If you wanted to get rid of the plug on the Volt, you would need a battery with 6-7kwh of energy storage, and yes, it might have to be a battery chemistry that is more optimized for power density than the current Volt battery chemistry in order to supply peak power. Battery cells that are optimized for power density generally store less energy, so the pack’s physical size and weight might be a little more than a 6-7kwh pack made from Volt cells.

    The underlying point is this: If you want a non-plug-in car, a full hybrid is a much better solution.

    It doesn’t make sense to shrink the Volt’s battery and remove the plug. This would be more expensive than a full hybrid, and offer no real benefit. The benefit of an EREV (aka series hybrid) only comes into play with a fairly large battery, and the electric range that comes with it.

    Another way to look at it is this: If you want a fairly large battery for electric range, then you have enough power to run the wheels from the electric motor and batteries alone, which means you can disconnect the engine from the wheels and remove the transmission.

    ————————————————————————————-
    I don’t think it’s an either-or scenario. In other words, we’ll need nuclear power, electric cars, cellulosic ethanol, and other things to become energy independent.

    Liquid fuels have dramatically higher energy density than any battery (including EEStor), so long distance travel by air, land, and sea will continue with liquid fuels for the foreseeable future. We need bio-fuels to cover this.

    For passenger vehicles, the vast majority of miles will be converted to electric, and nuclear power will be a key player here. But even on the day when BEVs get 250 miles of range, cost $25K, and charge in 10 minutes, people still won’t buy many of them until filling stations everywhere offer fast charging. Converting all of the filling stations will cost trillions of dollars, and will probably take 25-50 years to completely make it’s way into rural areas. So although the lion’s share of car miles may be converted to electric, people will still be using liquid fuels for a long, long time – probably the rest of our lifetime. This is why we need cellulosic ethanol.

    So far, nobody has ramped up cellulosic ethanol because the demand for ethanol is currently low, and corn ethanol is enough to supply it. When 30-40% of the cars on the road are FlexFuel, most gas station owners in the country will start offering E85. Converting a gas pump to E85 is trivial. At that point, demand for E85 will ramp up very quickly. This will trigger serious investments in cellulosic ethanol, and the supply will follow.

    Reducing battery capacity would make Volt much more affordable.

    As for needing 6-7kwh of energy storage, that simply doesn’t make any sense. All along there’s been talk of how the Volt engine is so big it is almost overkill. Now you come along and claim it produces so little electricity that it must depend on a battery-pack with 4 times the capacity of the one in Prius.

    The Volt engine should be able to sustain charge. True, it efficiency may drop to an undesirable level during times of extreme demand. But requiring so much excess is hard to believe.

    The Volt uses a 1.4L Atkinson cycle engine. The Aktinson camshaft is tuned for high fuel efficiency. The downside of this engine tuning is low maximum power output, only around 70hp. Since this is way too low for acceleration and uphill driving, the Volt requires additional electrical power from the battery to achieve reasonable performance when the engine is running.

    A while back, there was a “Pike’s Peak” article here on gm-volt.com:
    http://gm-volt.com/2008/09/02/the-pikes-peak-question-chevy-volt-and-the-infinite-hill/
    This outlined what would happen with the Volt on mountain passes, and why having 30% of a 16kwh battery in reserve is a good thing for such situations. This formed the basis of my estimate of 6-7kwh battery size for a non-plug-in Volt. As always, we can only form estimates about other options from the information we get from GM.

    There were also a couple of articles on gm-volt.com where GM floated the idea of a 20-mile Volt at reduced cost. Here’s one of them:
    http://gm-volt.com/2008/06/16/possible-future-chevy-volt-options-version-one-will-have-40-miles-ev-range/
    But then GM later seemed to back away from that by saying 40 miles was the right size. So apparently, GM looked at a lower range and found out it wouldn’t save that much money.

    Also, don’t be surprised if the actual price of the Volt comes in lower than people think. At the time congress was debating the amount of the plug-in tax credit, GM said they would need 2 batteries over the lifetime of each Volt, and that would drive the price up to $40K. Then after they passed the $7500 tax credit, Lutz said battery testing now shows that only one battery is required. I’m betting GM will surprise everyone with a price well under $30K after tax credits.

    But as always, predicting the future is imperfect. The information we have now can change at any time.

    LIFE-CYCLE COST

    The plain fact is that Lithium is much more expensive than NiMH or lead-acid from a life-cycle cost perspective; and A123 was one of the more expensive LCC items.

    No one can explain why GM fails to use NiMH, which is the lowest cost and longest-lived battery, the only standard and proven EV battery that lasts longer than the life of the car.

    Lutz just smiles and babbles when NiMH is mentioned; that was the superior battery that GM tried to suppress in 1996, and sold control of to Chevron in 2000. Then Chevron sued Toyota, and now it can only be used for hybrids that can’t plug-in. But it’s best for full EVs, like the EV1, HondaEV and Toyota RAV4-EV; make no mistake, NiMH is still running fine after 6 or 7 years in our all-electric Toyota RAV4-EV.

    @ Dave G

    Yes, it’s implicity included in the calculation, which is final output (miles) for original input (kWh energy), for direct comparisons of net output/input efficiencies.

    What I’m measuring is how much energy, measured in kWh, it takes to go a mile for different vehicles. What’s in between for drive train efficiency is already reflected in the calculation results – it’s original amount of fuel energy in, translated to kWh, for the final number of miles traveld out. That includes all the mess in the middle. I think that the reasonableness of my relative results (example – look at my results for the Prius) and the fact that no-one in this thread reported anything different using that metric says that I’m doing it right (I’m just following US EPA and DOE published official methods for efficiency metrics, which they bizzarely fail to report the results on on their own site for all vehicles). If you have different numbers to report in the metric of kWh / 100 miles, please do so.

    I will not buy this American car with a Korean battery.

    This is not just a simple question who delivered a few battery packs for testing. This is a much bigger economic issue. We need jobs here, we need to invest in our innovation, we need our tax dollars going to American suppliers.

    I do not understand why people think electric cars are cleaner.
    INFACT electric cars are more pollutant than any other car.
    New cars have catalytic converters on them so fact is exhaust is cleaner than what goes in. “2005 & newer”
    Electric power is from coal burning plants, (no filter) Nuclear power plants 250 degree plus water dumping in the ocean millions of gallons per second. Dumb asses.
    I am an engineer working in South Korea Now, and have a public company. That has developed the only clean electricity machine in the world.
    The ocean his being heated by Nuc plants and Earth rotation changes. NASA test fuels pushing millions of pounds of thrust against the earth in the WRONG manner dumb asses.
    People simply don’t Think.
    Am I the only one that can see?

    Further more I am a big GM fan,
    Did you know they developed the nickel hydride battery then sold patent rights to chevron that now can tell companies like Mercedes Benz NO NO… and are making billions on all the batteries around the world.
    People simply don’t think.
