Abstract:

© 2016 IEEE. This paper presents a control scheme combining SoC balancing and voltage/current regulation for a distributed battery system based on fly-back converters. In discharging operation, the proposed control scheme consists of two control loops. The first control loop is designed to regulate all battery terminal voltages to be identical, thus SoC imbalance issue is solved from the root. The other control loop is designed to regulate the output voltage. These two control objectives are combined into one system. In charging operation, the flyback converters are operated in discontinuous conduction mode (DCM). As a result, the charging power of each battery is identical. Therefore, SoC imbalance issue is avoided. The analysis of the control scheme and prototype validation based on flyback converters are provided to illustrate and demonstrate the proposed control scheme.
