Well in Chicago it will cost 276 dollars a year added to car registration for loss gas tax. As far as battery charge, I think its free at refueling sites....for now at least. At home, have no idea but it cant be cheap.
Our local Walmart put in electric charging stations a couple of months ago. They require a credit card to activate.
I have no idea how much they cost since I don't have an electric toy, but I bet it isn't cheap.
