Electric cars support 'charging schedules' - my utility gives me discounted electricity to charge between midnight and 8AM, and it took about 5 minutes to setup. I plug in my car when I get home from work, and it happily sits there until midnight when it starts charging (and when the grid is otherwise unstressed).
