Driving and regenerative braking method for energy-saving wheel motor

In recent years, with the environmental consciousness enhanced, the development of electric vehicles is gradually taken seriously. However, the traveling range of the electric vehicles can not compete with the ability of the existing internal combustion engine vehicles, which is one of the most important factors of hindering the development of electric vehicle. Therefore, the regenerative braking method is proposed in this paper which could convert the kinetic energy into electric energy and produce a reverse torque to reduce the speed of the motor without adding any other components to the original controller. For the part of experiment, the dsPIC30f2010 manufactured by microchip is utilized as the core controller, which integrates the regenerative braking method to design a driver for the applications of the electric motorcycle. Finally, this theory is confirmed that there are exactly have an extra energy recharge the battery when the motor-speed descended. That is absolutely revealed that the algorithm of this paper proposed is available.
