As an important part of battery management system (BMS), battery equalization technology is of great significance to improve the utilization efficiency of battery energy and the mileage of automobile, as well as to prolong the service life of battery. This paper introduces the mainstream equalizing circuit and equalizing control strategies, as well as the estimation algorithm of equalization reference variables, points out their advantages and disadvantages, and finally analyzes the future improvement direction of equalizing technology in combination with the current.
