Research on intelligent control system of active equalization for charging station of electric vehicle

摘要

In order to improve the quality of electric vehicle battery, this paper presented an intelligent active equalization system for electric vehicle charging station. It applied equalization mode of release and supplementary to balance battery energy, and applied centralize - decentralize structure to build the system. Inductance and capacitor is applied to store up energy and transfer energy for feedback of energy. Fuzzy control technique is applied to control process in system. Simulation results show that the system can realize to balance voltage of batteres when charging or no-charging, and meet the requirement of electric vehicle charging station.
