Modeling and Simulation for Super Capacitor Braking Energy Recovery Process of Micro EV
Super-capacitor is suitable as braking energy storage device for electric vehicle because of its high charge and discharge rate, long life, simple structure and reliable performance advantages. When driving motor of the electric vehicles runs on regenerative electric power state, it can not only provide braking force, but also charge to the energy storage device to recover the kinetic energy, thus endurance mileage of electric vehicle can be extended considerably. In this paper, braking energy recovery model was built by using the Matlab/Simulink software, and whole vehicle model based on automobile theory, the motor efficiency model and super-capacitor model were mainly included. Meanwhile some researches were made on the simulation, and the impact of the super-capacitor on the braking energy recovery was analyzed.
