My project is to design and make the regenerative braking device by the characteristics of Nd-Fe-B permanent magnetic materials of super magnetic force. The core mechanism of the regenerator includes two parts: One is the magnetic storage, this mechanism recovers kinetic energy from part of braking kinetic energy and use this power to restart or fast speed the vehicle. Or this energy can be used for acceleration by quickly releasing the stored energy. The other one is a non-contact transmission mechanism. This mechanism can be used as an auxiliary device of the automobile’s ABS system. Energy normally lost though frictional heating during braking can be reduced. This part of the system also improves the efficiency of energy recovery and provides a more stable braking process. This mechanism is the transmission function of the magnetic potential energy saving device. The regenerator is based on the principle of magnetostatics, the use of Nd-Fe-B permanent magnetic materials, no external power supply, and can work stably for a long time. Magnetic energy storage can be rapidly released in a very short period of time,
