为了能在试验室环境下研究分析各种电动汽车蓄电池在实际工况下的充放电特性,研发了电动汽车蓄电池性能智能分析试验台.系统采用晶闸管控制模块、IGBT模块为主要结构构成充放电主电路；设计了多功能采集卡接口电路、IGBT驱动保护电路；实现了高压充电、低压快速充电、恒流放电等充放电方式,既可以程序自动充放电又可以手动分步充放电；并在Windows98下用VC++开发了一套可视化、智能化的系统应用软件.试验台集充放电于一体,在技术上具有先进性.实验表明:试验台样机运行稳定,具有较高的应用价值.%In order to research and analyze the charging and discharging characteristics of the storage batteries of various electric vehicles in practice in the laboratory, the system used thyristor-control modules and IGBT modules as the main structure of the charging and discharging circuits. This paper designed the interface circuits of the multifunction acquisition-card and the protection circuits of the IGBT driver. It realized charging under high voltage, fast charging under low voltage and constant current discharging. The system can charge and discharge automatically or step by step manually. And under the Windows98 system,a set of visualized and intellectualized system application software was developed. The experiments show that the development of the test-bed is advanced. The test-bed runs stably,securely,reliably and possesses very good research value and usage perspective.
