摘　　要：我国电动汽车续驶里程测试标准一直沿用欧洲新欧洲驾驶循环工况,且在常温条件下进行,与中国实际道路情况、环境温度存在一定偏差,这也是实际续驶里程和公告续驶里程产生差异的主要原因。为使测试结果与车辆实际里程更为接近,将中国乘用车行驶工况作为测试工况曲线,开展了5款市场主流电动汽车的续航测试,考虑到我国国土跨越多个纬度、北方地区四季温差明显等因素,还研究了电动汽车在高、低温情况下续航能力的变化规律。研究发现,对于电动车而言,中国乘用车行驶工况与新欧洲驾驶循环工况测试结果相差不大,但是环境温度会明显影响电动车的续航、电耗以及表显里程准确度等性能。The driving range test standard of electric vehicles in China has always been carried out under New European Driving Cycle working conditions in Europe, and it is carried out under normal temperature conditions. There is a certain deviation between the standard and the actual driving range, the environmental temperature in China, which is also the main reason for the difference between the actual driving range and the announced driving range. In order to make the test results closer to the actual mileage of the vehicle, this paper took the China Light-Duty Vehicle Test Cycle-Passenger as the test condition curve, and carried out the range test of five mainstream electric vehicles. Considering the factors such as China’s territory spanning multiple latitudes and the obvious temperature difference of four seasons in Northern China, the variation law of the range ability of electric vehicles under high and low temperature conditions was also studied. It is found that for electric vehicles, the test results of China Light-Duty Vehicle Test Cycle-Passenger and New European Driving Cycle are similar, but the environmental temperature will significantly affect the performance of electric vehicles such as range, power consumption and accuracy of announced mileage.
