![]() ![]() That's going to shorten your range, no matter what kind of battery you have," Fisher said.īut there will be other breakthroughs. "When you're driving in the cold, you want heat. To deal with this problem, automakers such as GM and Ford sandwich their batteries' lithium-ion cells with materials that can heat or cool the battery when it is in danger of growing too hot or too cold. In an extended-range vehicle such as the Volt, that means the vehicle will switch over to gasoline sooner than it would in moderate temperatures. In electric vehicles, that means charging more often. "We're not seeing a big breakthrough in the next few years in terms of where you will suddenly be able to drive an electric vehicle and not have the battery be affected by temperature," Sherif Marakby, director of electrification programs and engineering at Ford, said in an interview Thursday.īatteries that are too cold are reluctant to release electrons, and batteries that are too hot don't live as long. But in the end, any of the technologies that are out there are very limited in terms of their capacity."Įven Ford seemed to back off a bit on its claims. "There's a new battlefield, and certainly the technology's moving very quickly, and everybody wants to say they're the best," Fisher said. Other reviews noting the limited range of electric vehicles in extreme temperatures probably are on the way. "I'm certain that a year or two from now, when they're actually in the market and they're actually showing cars, they will not be able to outperform us." "Nobody - Ford, Nissan or anybody - has anything better," he said. ![]()
