摘　　要：电动汽车动力电池是电动汽车充放电关键技术之一,电池性能的优劣直接影响着电动汽车的行驶里程和安全性,进而影响电动汽车的推广和发展。首先对磷酸铁锂电池的特点进行总结,在此基础上采用间歇放电法测试得到了实验测试下动力电池的OCV-SOC曲线,经曲线拟合确定了OCV-SOC模型的参数;建立电动汽车充电的电池组模型,并在PSCAD环境中进行恒流充电仿真,通过仿真与实测对比验证了模型的准确性。Electric vehicle batteries is one of the key technologies for electric vehicle charging and discharging, whose performance has a direct influence on the electric vehicles＇ mileage and safety, thereby affecting the promotion and development of electric vehicles. The characteristics of lithium iron phosphate were summarized. By using intermittent discharge method under laboratory testing, the power battery OCV-SOC curve was obtained, whose model parameters were determined by curve fitting and a battery model suitable for electric vehicle charging was built. A constant-current charging simulation was implemented in PSCAD environment and its accuracy was verified through comparison between simulation results and actual curves.
