ElI5: Why do electric vehicles struggle in the cold?

1.88K viewsEngineeringOther

I’ve always heard that EVs are not a great option if you live in really cold areas due to them not being very efficient in the cold. Why is that? And do gas powered vehicles have the same issue?

Cold batteries means bad-performing batteries, just like with an ICE car battery struggling to start the car on a cold morning.

Something like a Nissan Leaf would be bad in the cold because it doesn’t have much in the way of battery temperature management, although I think heating was added as an option recently. Tesla and Cadillac, and surely others, have full battery temperature management. They can also start heating your plugged-in battery long before it’s time to leave in the morning so you leave with a warm battery and a full charge. You will use a little more energy keeping them warm on the trip.
