Abstract

A heating method for lithium-ion battery is studied based on a simplified first principle electrochemical model. The criterion for avoiding lithium deposition is converted into current constraints under different temperature and state of charge. An experimental platform with closed-loop pulse current control function is built, by using of which, the effectiveness of the heating strategy is verified through heating a 18650 cylindrical LiFePO4 battery 100 times. The results show that no capacity fading is observed.
