I live in the Rocky…
I live in the Rocky mountains at around 9k ft in elevation where the temperature gets below zero overnight very frequently. I wouldn't have been able to get an EV without having a home charger. I don't have a level 2 charger yet and am able to get by with using a level 1 just fine. The range is certainly reduced. It helps to preheat the car and battery while still on the charger.
