You forget to charge and you have to wait it out. How about swapping in a pre-charged battery at the charging station, instead of charging the one you brought with you? Some EV idea posted recently on Hacker News used this plan. If it's too hard to swap the large battery for an electric car, at least have a small secondary battery that can be swapped and can get you home.
