You don't seem to understand battery heating or L-1 charging. The battery heater only comes on in single digit Fahrenheit weather, and only uses 300 watts. Preheating the car is entirely separate.
I understand the difference between pre heating the car and heating the battery. I didn't know that it was only a 300 watt heater.
My reading has lead me to believe that if it's cold outside and the car starts running the battery heater and you're on L1 charging, it will use the battery to run the battery heater because the L1 can't keep up with the heater and charging.
On a 20 amp outlet you can only draw 1960W (16A @ 120V) as a continuous load. (According to the NEC anyway) is 1600-1900 watts enough to charge the battery to 40 miles of range in 10 hours? Or am I misunderstanding something here?
The builders who built my house screwed me there anyway...I only have a 15A circuit out in the garage.
