The recharging does take many times longer than filling a tank - some hours instead of 30 seconds to a few minutes often the longest wait is in the queue to pay., - The only way to do it that fast electrically, would be battery exchange, which is not being seriously considered for anything bigger than some electric motorbikes at the moment. - though as we can use regeneration for braking, there is less energy needed on a stop-start journey, as you only drain the batteries when you are accelerating and overcoming friction and air resistance. You still need motor power of some tens of KW and you do NOT get back any that which is used for prime moving, just the fraction that would have gone on heating brake pads, and wasted idling in traffic jams, but that can be half of it, so is very much a saving worth having.
