Auto club AAA says, the range of electric vehicles can be greatly reduced, by up to 57%, depending on the temperature outside. Greg Brannon, AAA's director of automotive engineering said, "We expected degradation in the range of vehicles in both cold and hot climates, but we did not expect the degradation we saw." It tested the vehicles for city driving to mimic stop-and-go traffic between December and January, fully charging each EV, and then "driving" each on a dynamometer in a climate-controlled room until the battery was fully exhausted.
