abstract = "Enabled by an efficient reconfigurable topology, a multi-scale reconfiguration control method is proposed in this paper to maximize the capacity utilization and improve the efficiency of lithium-ion battery pack. A novel 4-switch reconfigurable battery topology is proposed. On this premise, an all-cell equalization method combining intra-module current sharing and three forms of inter-module energy distribution is proposed to achieve the maximum utilization of pack capacity. The real-time reconfiguration further promises an efficient charge transmission whenever the pack voltage lays outside the expected threshold. A lab-scale prototype of the reconfigurable battery pack is built for testing. Experimental results validate that the proposed design and reconfiguration control method can improve the LIB pack capacity utilization and pack efficiency by 10.96% and 14.34%, respectively, without any redundant design.",
