Ni-Cads are very good for taking a fast charge. The generator can be sized for very intermittent duty, like a starter motor, and made light rather than particularly efficient. However, even pure electric cars need mechanical brakes for the peak loads. With a reasonable size dedicated electric brake, you'd still spend a lot of time slowing down. I don't know if it would pay off.
