Thinking about getting an EV? Better move to a balmier state.
“It turns out batteries are like people. They love room temperature,” Bill Wallace, director of Global Battery Systems at GM said at an energy forum at the University of Chicago. He had come under fire, ammunition courtesy of Consumer Reports which said its tests showed the battery’s range of the Chevy Volt would last only 23 to 28 miles in cold weather.
The next day, Ford tried to make hay on the ruckus and issued a press release, titled “Cold Weather No Problem for Ford Focus Electric’s Liquid-Heated Battery System.”
Bill Wallace disagrees. “Nobody — Ford, Nissan or anybody — has anything better,” he told the Chicago Tribune. “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.”
Jake Fisher, a senior automotive engineer at Consumer Reports Auto Test Center thinks that “in the end, any of the technologies that are out there are very limited in terms of their capacity.”
Ford is backpedaling. “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.
The Chicago Tribune smells a climate change in reporting an thinks that “other reviews noting the limited range of electric vehicles in extreme temperatures are likely on the way.”
Consumer Reports recommends to get a hybrid.
