摘 要：In this paper,a cell balancing circuit for the Lithium-ion battery pack based on the Flyback topology is proposed.Balancing the lithium-ion battery pack is often employed to improve the energy utilization and lifetime of the battery.The proposed circuit uses the minimized power path to simplify the circuit and optimize the balancing efficiency.This paper shows the details of the balancing circuit structure and working principle,introduce the design of the balancing transformer and its theoretical analysis.Finally,experimental results are presented to verify the theoretical analysis.
