Abstract

In this study, a new bidirectional boost converter- based battery state-of-charge (SOC) active equalization system via an adaptive backstepping sliding-mode control-based balancing strategy is proposed. The system configuration and modeling are developed by analyzing the equivalent circuits of the battery and bidirectional boost converter. An adaptive backstepping sliding-mode control with the balancing selection strategy is subsequently applied to implement the regulated charging and discharging of battery cells, which possesses the capability in addition to against the external disturbance as well as parameters variation. Finally, a comparative simulation for battery cells' equalization according to the same balancing strategy between the proposed bidirectional boost converter-based system and the typical top-down equalization scheme is carried out, and the results indicate that the proposed system can shorten the equalization time about 9.8 %.
