Research on the high speed inductor-based active battery equalization schemes

Abstract

Series battery equalization can improve battery charge and discharge reliability and extend battery life. It requires a higher requirement in battery management system (BMS). This paper introduces the high speed inductor-based battery equalization schemes. It can realize energy transfer between the cells and batteries by charging and discharging of the inductors. Thus the equalization time can be improved. Finally the simulation and experimental results verify the theoretical analysis.
