Editorial: Between The Lines: GM's Volt Development Spin Cycle

As rumors filter in about GM’s Volt battery program, the faithful must be experiencing a certain amount of restless discomfort. After all, it’s not like this couldn’t be seen coming. Let’s just say that when I asked at SEMA last October the guys from A123 Systems (then bidding on the project) about the Volt battery development program, they took full advantage of the fact that SEC silent periods don’t forbid eye-rolling. Though non-verbal communication can (and in this case, did) speak volumes, we like to get our facts in writing. Which, thanks to the truth-proof wall surrounding the Volt’s development, usually means going through GM’s PR-exercise interviews with reliable Volt boosters and mining them for some kind of meaning. And hey, there’s an interview at Volt cheerleader HQ gm-volt.com which suggests that the Volt’s battery development is being rushed. And engineers are complaining to blogs? Fancy that!

GM-volt.com’s Lyle Dennis sat down with GM’s head Volt honcho Frank Weber for a sanitized-for-your-protection update on General’s moon-shot gambit. So what is happening right now, according to Weber?

We have been using the winter for winter tests . . . Now what’s happening is the true development work that you say OK this is the temperature of the battery, and this is the temperature of the system, and this is what happens when you are plugged in, etc. There are parameters that we call calibration, you have the basic software functionality on those cars defined, and then we start to calibrate it looking at the temperature and when to we start it, what is the true power of the battery at a certain temperature, etc.”

Any of this sounding intelligible or reassuring yet? This is supposed to be GM’s chance to thrill the credulous faithful, and the best Weber can come up with is “start to calibrate?” Don’t worry, it gets worse.

“What you know is what the behavior is for the cars that we are testing, and then you make an assumption for how a component will behave over time and how it will behave under the same situation in several years. This is what we call accelerated testing. This gives you some indication of durability. The piece that is tricky and interesting about the battery is to do a really accurate extrapolation of the true behavior. For a mechanical part this is very simple. For a mechanical part you can replicate its lifetime and find out when it will break. The battery is electrochemical and its more difficult to make those extrapolations. This is part of the learning we have to do, battery learning between the battery supplier LG and us. By the way this is still the element of risk. This is also why we are unable to get the car out any sooner. It is those things that have to be developed now with the components that are representative of the production vehicle. There is no way to do this any faster.”

If GM would just admit that the “late 2010” launch date is toast, this wouldn’t even qualify as spin. But then we don’t exactly live in a world where you can just say “it’s complicated, we don’t know when it will actually be done, now where’s my NSFWing bailout” is it? Or is it? I digress.

In a separate post, Lyle Dennis predicts public test drives this summer, putting faith first in spite of more damningly ambiguous talk, this time from GM’s John Lauckner. Saying “we need an experience where people say ‘Wow’ this is really something special,” Lauckner reveals that GM has “laid out all of the concepts that we want to use and written a lot of the preliminary code,” for the Volt’s “software-driven” driving experience.” Concepts. Preliminary. Wow. Lauckner continues:

“I would say that conceptually we’re most of the way there if not all of the way there, but there’s a lot of work to be done still to make sure that the whole thing operates seamlessly. [GM has to] love this thing a little bit to make sure that you not only get it that it actually works but you get it working in such a way that its completely intuitive. We need the time with the car and we need the time over a wide variety of conditions to simulate certain things, so that we can see just exactly how the car is going to behave and what sort of information the driver is going to get to make sure everything works in as seamless a way as we can possibly make it.”

Love your own product? Really? You’re only going to be asking $40 grand for the thing. And though both executives note its importance, time is the one thing GM doesn’t have. Weber reveals that the engineering freeze on the first true Volt prototypes or integration cars will occur “within days,” and that these integration models will be built and tested sometime later this year. If GM could simply let its executives just say what they hint at (conceptual, preliminary, this thing takes time) and let the “late 2010” date slip, their troops on the ground might not be grousing that the battery system is an “epic fail.” Instead it’s being rammed through and damn the torpedoes. This won’t end well.

    As I understand if they had been able to put the niMH batteries in it (as in if they hadn't sold them to Chevron...) then we'd have a plugin with twice the range or more... Something about the Lithium battery not tolerating being used flat b/c it damages the battery. Consequently they put in a big battery, allow the car management systems to use a little of it and then start the engine to do the big work. With a NiMH battery they could have used a battery the same size and gotten some serious miles out of it with proven durability...

    I love revisiting old TTAC articles such as this one, just as a reminder of how opinionated and wrong these self-appointed automotive "experts" can be. On just about just about anything to do with the industry. Case in point, this obvious tool Mr. Edward Niedermeyer who apparently fancies himself as an arm-chair CEO and chief engineer. Here's a nickel Mr. Niedermeyer, buy a clue! The Volt remains an unequivocal success- no thanks to you!

  • Honda1 Unions were needed back in the early days, not needed know. There are plenty of rules and regulations and government agencies that keep companies in line. It's just a money grad and nothing more. Fain is a punk!
  • 1995 SC If the necessary number of employees vote to unionize then yes, they should be unionized. That's how it works.
  • Sobhuza Trooper That Dave Thomas fella sounds like the kind of twit who is oh-so-quick to tell us how easy and fun the bus is for any and all of your personal transportation needs. The time to get to and from the bus stop is never a concern. The time waiting for the bus is never a concern. The time waiting for a connection (if there is one) is never a concern. The weather is never a concern. Whatever you might be carrying or intend to purchase is never a concern. Nope, Boo Cars! Yeah Buses! Buses rule!Needless to say, these twits don't actual take the damn bus.
  • MaintenanceCosts Nobody here seems to acknowledge that there are multiple use cases for cars.Some people spend all their time driving all over the country and need every mile and minute of time savings. ICE cars are better for them right now.Some people only drive locally and fly when they travel. For them, there's probably a range number that works, and they don't really need more. For the uses for which we use our EV, that would be around 150 miles. The other thing about a low range requirement is it can make 120V charging viable. If you don't drive more than an average of about 40 miles/day, you can probably get enough electrons through a wall outlet. We spent over two years charging our Bolt only through 120V, while our house was getting rebuilt, and never had an issue.Those are extremes. There are all sorts of use cases in between, which probably represent the majority of drivers. For some users, what's needed is more range. But I think for most users, what's needed is better charging. Retrofit apartment garages like Tim's with 240V outlets at every spot. Install more L3 chargers in supermarket parking lots and alongside gas stations. Make chargers that work like Tesla Superchargers as ubiquitous as gas stations, and EV charging will not be an issue for most users.
  • MaintenanceCosts I don't have an opinion on whether any one plant unionizing is the right answer, but the employees sure need to have the right to organize. Unions or the credible threat of unionization are the only thing, history has proven, that can keep employers honest. Without it, we've seen over and over, the employers have complete power over the workers and feel free to exploit the workers however they see fit. (And don't tell me "oh, the workers can just leave" - in an oligopolistic industry, working conditions quickly converge, and there's not another employer right around the corner.)
