How cold is too cold for electric cars?

In subzero temperatures, EVs may lose even more than 30% of their power.

 For instance, according to AAA, BEVs subjected to temperatures of 20 degrees

Fahrenheit may lose up to 41% of their electric range. That may be discouraging for commuters

 who must drive long distances in their EVs during inclement weather.

However, an EV loses power for several reasons other merely the cold. According to AAA, at 

temperatures of 95 degrees Fahrenheit or above, a BEV like a Tesla Model 3 might lose the 

same or more as 17% of its charge. Driving ranges are less vulnerable to heat than to acute cold, though.
