In an electric only powered car, how are the heater and air conditioner powered?
Back in 1994, I was the CFO of a company that purchased a surplus US Postal Service electric car. It ran on two eighteen volt banks of batteries, and had a 220 volt charger that we hard wired into the back of our building. The top speed was fifty miles per hour, and it had approximately a twenty mile range on fully charged batteries. In the case of this vehicle, there was no air conditioner. The heating system for the car was a small gasoline fired heater, with an eighteen volt fan to direct heat throughout the car that ran off of the front battery bank. I always got a kick out of pulling up to my local gas station in a perfectly silent vehicle, with an electron symbol on the doors, and purchasing fifty cents worth of gas for the heater. It always drew a few stares!
