Assuming gas is $3.75/gal where you live, that is $630. If you spent $630 on charging your car in one month then you either drive 3000 miles a month or have a problem with your electric meter. Assuming you live in the state with the highest electricity prices that isn't Hawaii (because then we couldn't assume $3.75/gal for your gas), your rate is $0.34/kWh. That means you 1853kWh.

Assuming you drive the least efficient EV, the Hummer, which goes 329 miles on 213kWh, you would have to drive 2862 miles in one month to spend $630. So for the worst case electrical price, with the worst case EV mileage, with average gas prices, you are driving a lot more than most people to spend 14 twelve gallon tanks of gas worth. For reference, switching that Hummer to a Bolt would only cost $278 to drive 2862 miles.
