Regenerative braking system for electric vehicle is restricted by many factors such as control strategy etc. in the process of braking energy recovery. Taking electric vehicle as a research object, the structures of regenerative braking system are classified and introduced in accordance with arrangement of the driving motor. And combining with the current research status, this paper analyzes the main influencing factors of regenerative braking. On the basis of the main influencing factors, three common regenerative braking control strategies are described and analyzed. According to comparison and analysis, the results indicate that the parallel regenerative braking control strategy or the composite parallel control strategy which possesses great prospects for development can better meet the needs of energy management control for electric vehicle.
