A fire involving a Chevrolet Volt that had undergone government crash testing has led to authorities investigating the possibility of requiring emergency responders to drain the batteries of electric and hybrid vehicles following a collision.
A Volt that underwent a 20 mph side-impact crash test caught on fire several weeks later, causing the Volt as well as surrounding vehicles to catch fire. The crash test was said to have punctured the vehicle’s lithium-ion battery pack. General Motors said that the fire occurred because the battery had not been drained following the crash, though NHTSA officials said that “we don’t see the risk of electric vehicles as being any greater than that for a gasoline vehicle.”
200,000 car fires are said to occur in the United States annually, but the issue regarding a battery puncture has led NHTSA and GM to investigate the matter closely, despite both insisting that the vehicle is as safe as any other conventional car. GM currently dispatches a team to drain the battery of any Volt that crashes, and is hoping to make the necessary tools available to dealers in the coming year.
