Re: Bolt Efficiency, How Accurate?

You have to add a fudge factor to that to account for the fact that the car's built-in charger isn't 100% efficient, so it draws more power from the wall than it delivers to the vehicle. If you had an energy meter wired to the outlet you use to charge the car then that would give you the most accurate figure.

Best way for me, since I only charge at home, is to look at the juicebox kWh that was put in. That would include the loss while charging.
