常温环境下直流充电桩充电效率评价

Charging Efficiency Evaluation of DC Charging Pile under Normal Temperature

选择三辆典型常规纯电动车(BEV),一辆典型混合动力汽车(HEV)分别进行SOC 2%电量、SOC 20%电量、SOC 30%电量直流充电测试,测试过程中分别在充电桩和电网之间及充电桩和车辆插头之间设置测量点,测量桩前及桩后充电量及充电功率、电流等数据,分析直流充电桩充电效率,充电桩自身损耗等。

Three typical conventional electric vehicles and one typical hybrid electric vehicle(HEV) were selected for charging test at 2% SOC, 20% SOC and 30% SOC. During the test, measuring points were set between the charging pile and the power grid and between the charging pile and the vehicle plug to measure the charging amount, charging power and current before and after the pile, and the charging efficiency of the DC charging pile and the loss of the charging pile itself were analyzed.
