Recently, the rise of the concern about an environmental problem or an energy problem is asked for the low-emission and low fuel-efficient car. As solution, the development and the spread of cars using a fossil fuel, which used electricity directly, are directly expected. Then, in order to develop a small electric powered vehicle, we purpose of a further performance is the vehicle for energy saving competition "World Econo Move (WEM)" We carried out for charge of a battery by the putting in hot water, regeneration of energy by capacitors. The result, we could slowdown energy is cut down 6% by the regeneration, and thereby increase the mileage at 0.6km compared to the last year.
