I ran a little experiment to get an idea of how much it would cost me to charge monthly, especially during the winter. I have a LR RWD.
I drove 698 miles between 11/15/18 and 12/15/19. I started and ended the experiment with the battery charged to 80% to keep it consistent. The temperature has been in the 30s for much of the month. I also park outside, and preheat the car in the morning, although not every time (preheat for 15 min or so). I don’t charge the car everyday. My work commute is a short 9 mile round trip. Using a meter that I installed near my panel box, I consumed 432 kWh. My rate is about 14cents/kWh.
summary: total cost to charge is $60.48. Total energy usage is about 619 watts per mile. In my area fuel is about $2.65 a gallon. To equate what I paid for electricity, I would have to have a gas car that gets 30 mpg.
