Design of Electric Vehicle Energy Regenerative Braking System Based on Super Capacitor

The necessity of the electric vehicle using energy regenerative braking system is described in this paper. Then the design process of the braking system with the super capacitor was discussed and the determination method and the control mode of the main technical parameters was analyzed. Using the system the electric automobile can realize regenerative braking in any common condition especially when the conventional regenerative braking can not be achieved. Under these circumstances the electric energy which is generated by braking process and stored in the super capacitor can output to the traction inverter DC link when the automobile is in the traction mode. So it is a good way to significantly reduce the electric vehicle energy consumption.
