Aren’t EVs bad in extreme weather areas, be it too hot or too cold? Unless those battery packs have hella insulation or cooling won’t they have longevity problems?
People have weird perceptions about EVs in cold weather. It’s simultaneously worse, but also not as bad, as everyone seems to think.
Range is impacted. My car keeps track of where my “charge is going” and in the winter, the car will condition the battery as you drive it to keep it in a nominal temp range. On a bad day here (10 degrees or lower) about 10% of my energy used goes to warming the battery pack. However, heating up the car for passengers is extremely energy intensive. Running the cabin heat on cold days can be over 25% of my energy usage. Heated seats and steering wheel are much more efficient at keeping you warm. So if I really try to save some energy, and preheat my car, I get about 180 out of 220 miles in the winter (when charging to 80%). If I’m running the heater and not keeping the car on the charger overnight, I might get 120.

Shitty Tesla chargers don’t work in cold.
Teslas are kinda shitty. It’s been known for a while.
In the cold some kinds of batteries can be more impacted than others, but unless it’s extreme the resulting capacity is still enough mostly.
