Research on Energy Management of HEV Lithiumion Battery

Abstract

Battery system is a more complicate and fragile link in the HEV vehicle. The performance of battery system directly affects the whole Energy and the function and cost of HEV system. Therefore, energy management of battery system can optimize the working state of battery and make it match better with other system. The paper mainly discusses the charging management of Lithium ion battery and energy feedback of braking. Results of experiment demonstrate the proposed energy management strategy has an obvious effect of saving energy and can reduce the charging time and improve efficiency.
