Why has nobody ever thought of a removable electric car battery? You know how with a camping gas cylinder, you take it to be refilled, but they don't refill it while you wait, you simply get a full one in exchange? Why not do the same with the car batteries? A "petrol station" could have a big rack of batteries charging at whatever rate, and you simply pay, take a full one, and slot in your empty one.
