Cost of Driving an EV

She lives in Tennessee and I really don't have a clue what it cost her.
Powering it up at home on a 120 volt charger is slow. You get like three miles for every hour it's charging. I think most people spring for a 220 volt charger and it's much faster.
I think it's around $6.00 to charge it up all the way.

Fast or slow doesn't determine the cost from a monetary standpoint, power is power. I'd certainly opt for the 220v
