On really cold days the loss can be up to 40 percent especially when running the heater.
With temperatures dropping well below zero in many parts of the country this week electric car owners are experiencing the most dramatic real world cold weather test of evs since mass market battery powered cars were introduced three years ago.
There s no getting around it.
New research from aaa reveals that when the mercury dips to 20 degrees fahrenheit the average driving range of an electric car decreases by 41 percent.
Greg brannon aaa s director of automotive engineering said in a statement we found that the impact of temperature on evs is significantly more than we expected.
