Comment Offload the capacitor? (Score 2, Interesting) 457
I'm sure the smart folks have already considered this option for "fast charging", but why not have a big capacitor that stays plugged into your wall at home and builds charge slowly, but when you connect it to your car, it can very rapidly transfer the charge to your own capacitor. You'd basically be off-loading the slow-charge step to a place that doesn't move around anyway.
