With all this talk of electric cars, I have one simple question: how long does it take to recharge them, and how much electricity is used?

Let's, for the sake of this discussion, assume you have just made a 13 mile round trip to the grocery store, never exceeding 45mph or climbing any extraordinary hills. Let's also assume that you're plugging into an ordinary 15-amp convenience circuit to recharge.

Will you pop the breaker? If not, how long will it take to replace the power you've used? How many kilowatt-hours will you need?
