I've had my MY for a bit over 2 weeks now and am trying to figure out a method for determining the cost of home charging. I have a Tesla charger in my garage and by perusing my latest Duke Energy bill, I see I'm paying 13.6 cents/kwh including taxes/fees. (10 cents w/o). My one experience with superchargers on a quick trip to Charlotte cost 29cents. So is there an easy way to determine from the car computer what kWh I'm using in home charging ? It may be obvious, but not to me.
