#Volt

Forty miles without a single drop of gasoline. That’s been the pitch for Chevrolet’s Volt since it was just a concept. And it’s a claim that GM has been hammering hard on in promotional materials, advertisements and to the media. But it seems that the claim deserves an asterisk. Green Fuel Forecast‘s Sam Abuelsamid recently spoke with folks from GM’s Voltec battery development team. In the discussion of the Volt’s thermal management system, an inconvenient truth raises its misshapen head. “If you’re not plugged in and the battery is not conditioned and we’ve got to deal with the elements, right now we’re thinking 0-10°C we won’t use the battery. The more we can use it the better but we’ve got that area of refinement we’ll have to do as we get more of the engines, more of the vehicles, more of the batteries and tune it all up,” GM director of hybrid energy storage systems, Denise Gray tells GFF.
