Multi-objective optimization of a semi-active battery/supercapacitor energy storage system for electric vehicles

Song, Ziyou; Li, Jianqiu; Han, Xuebing; Xu, Liangfei; … - In: Applied Energy 135 (2014) C, pp. 212-224

This paper proposes a semi-active battery/supercapacitor (SC) hybrid energy storage system (HESS) for use in electric drive vehicles. A much smaller unidirectional dc/dc converter is adopted in the proposed HESS to integrate the SC and battery, thereby increasing the HESS efficiency and reducing...
