We talked with a repairman from Alaska to find out how cold can affect cars and hear about possible solutions.Solution: Granted, driving the EV isn’t the problem, but cold weather does impact an EV’s efficiency and performance.

Will car start when it warms up?

The battery may be dead in which case even if it is warmed up it will not start. A properly winterized car will tend to start at colder temperatures than one that is not.
