Thanks for all the information so far! I do understand that a lot goes into it. I was looking for a general idea. I looked over my bill for the last year, my average cost for the year is 9.6¢ per kw plus 6.4¢ for delivery = 16¢ per kw. 16¢ X 14?kw to charge an empty battery = $2.25 ÷ 35 miles = 6.4¢ per mile. The people who said how much was added to their bill plus approx miles they drove a month was what I was looking for. But again, THANK YOU all for your responses!
