EV Charge At Delaware’s average home electricity price of 18.70¢ per kWh, a Tesla Model 3 costs roughly $55 to drive 1,000 miles on home charging ($0.055 a mile). Filling the battery from zero costs around $17.10.
Delaware ranks #19 of 51 for electricity prices (1 = most expensive), so this is close to the U.S. average of $54 per 1,000 miles for the same car. A 30-mpg gas car would spend about $144 on fuel for those 1,000 miles at Delaware’s $4.33 a gallon, so home charging saves roughly $89 every 1,000 miles.
