摘要
目前电动汽车都会采用到驱动动力强劲的锂离子电池,在充电模式下保证锂电子电池组实现主动均衡控制,有效推进电动汽车电力系统良性发展,提升电汽车整体性能。文章中所探讨的是基于双向Buck-Boost拓扑结构的主电路主动均衡控制系统,它其中基于荷电状态SOC建立主要均衡判据,进而实现了对主动均衡控制策略的有效改进。简单研究了充电模式下的锂离子电池组主动均衡控制电路设计方法,锂离子电池组的SOC均衡控制策略,并对其设计控制方法仿真结果进行分析。
At present,electric vehicles use lithium-ion batteries with strong driving power.In the charging mode,the lithium-electronic battery packs are guaranteed to achieve active balance control,which effectively promotes the sound development of electric vehicle power systems and improves the overall performance of electric vehicles.The article discusses the main circuit active balance control system based on the two-way Buck-Boost topology.Among them,the main balance criterion is established based on the state of charge SOC,and the effective improvement of the active balance control strategy is realized.The design method of active balance control circuit of lithium-ion battery pack in charging mode and the SOC balance control strategy of lithium-ion battery pack are briefly studied,and the simulation results of the design control method are analyzed.
