摘　　要：本文以纯电动汽车为研究对象,开展了集体样车与同一样车的充电性能分析试验,通过试验数据结果,对整车充电控制策略、影响充电性能的关键技术指标等相关内容进行分析。试验结果表明:在低温环境下所有样车都可以正常启动交流充电,而在低温与常温车辆充电电量衰减比、充电时间衰减比略有差异;在同一样车的充电性能分析试验中,分析了低温与常温条件下充电电流趋势、电池输入电流、电池温度、最大充电电流的不同。In this paper, the pure electric vehicle is taken as the research object, and the charging performance analysis test of the collective prototype and the same vehicle is carried out under different conditions. The test results show that from the analysis of the collective prototype test, AC charging can be started normally in the low temperature environment. The charging power of most test vehicles has a certain attenuation compared with the normal temperature, and the charging time has a certain increase. The differences of charging current trend, battery input current, battery temperature and the maximum charging current under different temperature condition is analyzed.
