What I realized is that buyers don’t seem to know just how much it costs to charge an EV. I realized that I didn’t know how much it would cost to charge an EV either. But I wanted to find out. We all know exactly how much it costs to put gas in the tank – look at the lines if there is a one cent jump expected tomorrow – but electricity is more stable and more predictable. So how much does it cost to “fill up” an electric car?
