摘　　要：以使用阀控式铅酸(VRLA)蓄电池的独立光伏系统为研究对象,根据蓄电池端电压预测蓄电池的荷电状态来判断蓄电池的容量,采用CVT方式跟踪光伏电池最大功率来有效地提高光伏电池的工作效率,采用改进的二阶段充电法对蓄电池组快速充电优化充电过程。通过仿真验证了该方法可以有效地避免蓄电池发生过充电和最大限度地避免欠充电,从而延长蓄电池的寿命,并且提高了整个光伏系统的工作性能。system to maximum This paper predicted the state of charge of VRLA batteries in the independent photovohaic determine the capacities of VRLA batteries according to their open circuit voltage, tracked the power of PV cells by CVT method to effectively improve the efficiency of photovohaic cells, andused an improved two-stage fast charge method to optimize the charging process of VRLA batteries. By simulation it was verified that the method could effectively avoid over-charge and under-charge of VRLA batteries, thus extend the life of VRLA batteries and improve the overall performance of PV systems.
