Domestically its a twelve hour charge overnight on cheap rate. Easy
enough for those with garages and well within domestic supply limits.

That it might be, but I wonder if the local distribution grid could cope if
lots of us pushed up our consumption. It's one thing for the supply to
houses to be rated at 100A but quite another if we all draw 50A. That's
apart from the generation issue.
