    GM's solution to the Li-On Battery Problem

    According to Edmund's Green Car Advisor blog GM's solution to the overheating problems with Li-Ion batteries is...


    GM's Secret for Safe Lithium-ion Batteries: Cool It! General Motors Vice Chairman Bob Lutz raised eyebrows in battery development circles when he said recently that GM was “100 percent confident” that it has whipped the overheating problem that is hampering development of lithium-ion battery packs for electric and hybrid cars.
    Now the General’s secret can be told.
    Tony Posawatz, vehicle line director for GM's E-Flex electric vehicle platform, told Green Car Advisor during an interview in Detroit that instead of mounting a frontal attack on battery design for the Chevrolet Volt extended-range electric car that is under development, engineers circled around and attacked from the flank.
    “We’re going to use liquid cooling,” he whispered.
    Running coolant lines through the big array of lithium-ion battery cells that will store energy to propel the Volt and other models built on the E-Flex platform adds cost and isn’t as elegant as developing a battery that won’t overheat, Posawatz admitted. But it is enabling the automaker to keep on its self-appointed schedule: Volts in the market by 2010.
    Failure isn’t an option, he said. GM was recently savaged in the popular documentary, Who Killed the Electric Car?, for its decision to pull the plug on its first modern electric vehicle, the EV1.
    With the Volt, a car Lutz has said will be sold for under $30,000, GM has laid its reputation on the line. Asked if the project could wind up on the cutting room floor, Posawatz shook his head.
    “We’d never live it down,” he said.

    Yes lets tell everyone...so then they can do it. Does GM ever shut up about their plans?!

    Meh, I'll still be thrilled if GM can pull it off. Cheers to GM for being the first to solve this problem.

    You've got to appreciate GM's moxie and determination to "git 'er done" by whatever means possible. In time, I'm sure the technology will advance to the point where the batteries themselves operate cooler, but in the interim, this may be the most promising solution.

    News alert: this is not a novel concept. It is interesting that GM is doing it, but it is not like everyone and their cousin hasn't considered the idea.

    Hey it is done when you overclock a CPU...why not do this for the batteries. It is an 'Inventive Idea'.

    It's going to be intresting to see how everything works out for the new Chevrolet Volt. Hopefully the Chevy Volt will prove very successful for GM.

    How is this a secret? The Tesla roadster, on sale this fall, uses liquid cooling.

    There is an old saying in the domestic appliance industry
    "If it's to cold, heat it.
    If it's to hot, cool it"

    I'm sure they've gotten a few patents out of this admitedly crude design.

    Re: GM's solution to the Li-On Battery Problem

    GM talks WAY too much about products that are still years away. Why? Why can't they just talk about their current products?

    The new Chevy ads talking about the Volt is so much hot air on non-existent products, it's maddening. In the software industry, the term they use for this BS is vaporware.

    It's time for GM to shut up and deliver. They are setting themselves for a PR disaster when a competitor beats them to the marketplace with a Volt-like product. It happened with AFM just recently.

    I do agree that GM needs to talk about products that are months away, not years. In regards to AFM or DOD, Honda did beat them before GM reintroduced it. Cadillac had DOD back in 1983.
