Fast charging system of electric vehicle (EV) based on hybrid energy storage system

The electrical vehicles have become the research focus for the environment-friendly characteristics in recent years. As the core technology of the EVs, the battery technology influences the development of the EVs. The hybrid energy storage system can increase the life span of the batteries by improving their working condition, and how to shorten the charging time is also concerned. Two technologies are analyzed in this paper, and a control method for the fast charging of the batteries is proposed. Hybrid energy storage is utilized to maintain the stability of the system. At last, a simulation model is estabilshed in matlab/simulink to test, and the results verified the validity of the proposed control system.
