Improved charge control algorithm considering temperature of Li-ion battery

In this paper, Li-ion battery charging method of On-Board Charger(OBC) for Electric Vehicle(EV) considering temperature is proposed. Considering the characteristics of the Li-ion battery that varies with temperature, it is a method for charging while maintaining the proper temperature. It operates in three modes and maintains the proper temperature of the battery via self-charge·discharge. In this paper, analyzing the temperature characteristics of the Li-ion battery, it proposed a method for charging while maintaining the proper temperature. The proposed charge method is validated by experiment.
