中文摘要:
      提出一种应用于直流不间断供电系统蓄电池组单体电池均衡的桥式开关矩阵拓扑,利用LC均衡器进行能量的存储和转移,实现了能量从电池组中荷电状态(SOC)最高的单体电池向最低的单体电池转移,给出了参数设计方法,在避免迂回均衡带来蓄电池充放电次数增多的同时,延长了蓄电池的寿命,提高了均衡和能量转移效率。在Matlab-Simulink环境下搭建了均衡系统模型并进行了仿真,结果验证了所提出均衡策略的有效性和可行性。
英文摘要:
      This paper proposes a bridge switch topology for the equalization of DC uninterruptible power system storage battery, using LC equalizer to transfer energy from the cell with the highest state of charge(SOC) to that with the lowest SOC in the battery pack. The parameter design is presented. Avoiding the increase of the charge and discharge times of the battery brought by the roundabout equalization, the proposed strategy extends the working life of the battery and improves the efficiency of equalization and energy transfer. The equalization system models of battery pack and balancing circuit are built and the results of the simulation experiment verify the availability and feasibility of the proposed balancing strategy.
