These are numbers from the energy page.
I have no idea why this pack is doing so well. :!:
I definitely flog this car, because the electrons are mostly free. 
Except in the winter, I charge to full once a day and it's at that state for at most 4 hrs unplugged.
Lately I've been plugging in at noon so I pick it up at the end of the work day, fully charged for < 1 hr.
In hot weather this is a better plan.
