摘　　要：对锂离子电池进行充放电测试,是研究其性能、安全性的基础。提出了一种基于Lab VIEW的单节锂离子电池通用充放电测试系统,利用上位机Lab VIEW软件控制可编程电源和电子负载进行电池充放电,利用NI my DAQ设备实现电池端电压、电流和温度的采集,并且带有电池保护、数据记录和图形实时显示功能。该系统可根据用户需求完成恒流充放电、动态充放电等多种工况的测试,且数据采集精度满足电池性能研究的需求。As the charge-discharge tests of lithium-ion battery are of importance for studying the capability and safety, a single lithium-ion battery charge-discharge testing system based on Lab VIEW was proposed. Lab VIEW software was introduced to control the programmable power source and electrical loads for battery charge and discharge, NI my DAQ was adopted to collect the terminal voltage, current and temperature, and this system could implement functions like battery protection, data recording and graphic real-time display. Experiment results demonstrate that this system can meet the requirements of many conditions test such as the constant current or dynamic charge-discharge.
