摘　　要：系统一方面通过单片机系统实时采集蓄电池(阀控式铅酸蓄电池)电压、电流等参数,同时采用二次电压法计算蓄电池内阻和容量,另一方面通过嵌入式计算机系统对实时数据进行分析处理,得出蓄电池综合性能的评价,同时对评价结果进行网络发布。系统能实时在线测试蓄电池各项参数,通过蓄电池的内阻和容量预测电池寿命,保证变电站直流系统安全运行。On the one hand, the system can collect the real-time parameters of battery （VRLA） like voltage, current, and etc. by single-chip microcomputer system, and meanwhile compute the internal resistance and capacity by secondary voltage method. On the other hand, the real-time data were analyzed by the embedded computer system, the obtained results could evaluate the comprehensive performance of battery, and the evaluated results could be published in Web at the same time. The system could monitor the various parameters; the battery life could be forecast by internal resistance and capacity of battery which guaranteed the safe operation of substation DC system.
