That’s a pretty good idea, you can get a 40KW Generator for $20K New and under 10K used, $200 cash for an hour of charging and you are out of the cold.

Not your typical generator setup, plus the car/ power supply has complex handshaking for battery state, YOU CANNOT FAST charge a frozen battery or even a very cold one. The car tells the power supply to slowly provide sufficient power to warm the battery... and so much more.
