trig42:frankv:Jaxson: Once enough people arrive home from work and plug the car in over night, mixed with ovens and hot water use, you have a new peak period.
If a battery does require 12+ hours charging from (say) 5pm-6am, then it's not going to be pulling very much current from the grid.
Assuming a reasonably short battery charging time (say less than 8 hours), there's no reason why a car should be charging before (say) 10pm. In fact, the car could regulate its charge-up time itself, so is just fully charged at (say) 6am.
I wonder, can you use an EV as a UPS as well? Power goes down at home, plug in your car and keep the fridge/PC/TV going?
I believe this was the plan with the Leaf. You'd drive it around and it would power your house when you came home. Not sure if it was the Leaf or another brand of factory EV.
