GM Tinkers with Design, Battery for Rechargeable Car

Early versions of the Chevrolet Volt's battery packs are powerful enough to run the high-stakes rechargeable car, but dozens of issues remain before General Motors can start selling the revolutionary vehicle in 2010 as planned.

The Volt's chief engineer is on a tight schedule to figure out how the car will handle the batteries' weight, dissipate their heat and mechanically transfer their power to the wheels.

That's not to mention the list of issues that have nothing to do with the fact that the electric car plugs in to the wall for recharging.
