Research on Energy Feedback Strategy for Electric Vehicle

This paper analyzes the efficience of energy feedback on the whole range of speed in the process of driving , and gets the range of speed which is suitable for the energy feedback of electric vehicle. Mean while it deeply studies automotive braking strategy, and proposes the "Urban, High-speed"strategy which means step and dual control. The analysis of the specific situation of braking is added in the two different kinds of operating mode. The design of sliding gear can make the vehicle efficiently recycle potential energy on the downhill. By dynamically adjusting the current through the motor controller, the author intend to recollect the maximize energy under the condition of not affect the vehicles braking flexibility, security and reliability. Based on ADVISOR software in the ECE working conditions,simulation results for braking condition show that the electic vehicle can brake steadily and recover energy at most .
