电动汽车不同工况下的能耗试验对比研究

Comparative Study on Energy Consumption Test of Electric Vehicle on Different Cycles

介绍了目前电动汽车能耗试验工况循环的发展历程和研究现状,并选取3辆样车分别在新欧洲驾驶循环(NEDC)、中国轻型汽车行驶(CLTC-P)工况下进行常温续驶里程及能耗试验,对其续驶里程和能耗结果进行比对分析。结果表明,常温续驶里程及能耗受试验工况影响较大,同一车型在CLTC-P工况下的常温续驶里程会增加,同时能量消耗率会降低。

The development history and research status of energy consumption test cycle of electric vehicles are introduced,and 3 sam-ples are selected to carry out normal temperature driving range and energy consumption tests under NEDC and CLTC-P conditions re-spectively,the results of continuous driv ing range and energy consumption are compared and analyzed.The results show that the normal temperature driving range and energy consumption are affected by the test conditions greatly,and the normal temperature driving range of the same vehicle under CLTC-P conditions will increase,while the energy consumption rate will decrease.
