Research and Development Trend on Battery Management System for EV

Naxin Cui

Abstract

Battery management system(BMS) monitors various states of power battery in real time,has functions of state of charge(SOC) estimation,battery equalization,thermal management,CAN communication and so on,and serves as one of the key components and parts of the electric vehicle.The present researches situation of home and abroad is reviewed and the general structure of BMS,SOC estimation methods of power battery,battery equalization technology and battery thermal management technology are discussed.Finally,the future development trend of BMS is prospected.
