The most typical charge sessions are about three to four hours. I almost always charge at 56 amps. I generally try to have the charge sessions end somewhat close to when my wife is leaving, but tend to err on the conservative side, so they often end 30 minutes to an hour before she leaves.
Interesting. You charge at a greater current than I do... yet you seem to be more severely regen limited. Perhaps it's the greater time before you leave?
