大容量蓄电池测试仪的开发研究

Development and research of high capacity battery tester

铅酸蓄电池在制造、安装、维护阶段均需要进行不同的性能试验,以获得容量、内阻、寿命等信息,随着第三代核电技术的应用,大容量的蓄电池组也开始普及,这些大容量的蓄电池组试验放电电流高达1500 A、电压为220 V(DC),目前国内的蓄电池测试仪器无法满足试验要求。从大功率蓄电池测试仪的工作特点进行研究,探索开发途径,实现测试仪的可编程、组合使用、蓄电池单体监视功能。

The battery need different performance tests to carry out in the stages of manufacture,installation and maintenance,in order to obtain information such as capacity,internal resistance,life and so on.With the application of the third generation nuclear power technology,large-capacity batteries are becoming more and more popular.The discharge current of these large-capacity batteries is as high as 1500 A and the voltage is 220 V(DC).At present,the domestic battery testing instruments can’t meet the test requirements.This paper will study the working characteristics of the high-power battery tester,explore the development ways,and realize the programmable,combined use and battery monomer monitoring functions of the tester.
