Charging a li-ion battery when very cold is not good for it
- rebuilder 8y agoIsn't the Tesla battery temperature-controlled? I.E. you'd use mains power to keep the battery at a safe temperature when plugged in, so it should be OK to charge? I don't know if this is what they do but AFAIK they do manage the battery temperature.

What's neat is that while other vehicles like the Chevy Bolt have an electric heating element to warm up the battery a Model S actually just uses the inverter for the motor to generate heat. It can essentially intentionally waste power without moving the motor at all. Since it's on the same coolant loop this warms up the battery pack.
