How much does it cost you for a full charge?
$2.50 per night if the car is at 0% battery.
I usually pull in with about a 60% charge though, so it’s much less than that.
My power bill has gone up about $30 per month, but based on a very detailed spreadsheet we created at work, I pay around 19¢ per gal electricity equivalent. Added bonus is that I get free charging at work. A lot of businesses around the Metro Atlanta area are installing these.
