The invention discloses a method for judging the low-temperature discharge capacity of a new energy vehicle. The method comprises the following steps: step 1, a vehicle intruding process: fully reducing the temperature of the vehicle at a set temperature; step 2, cold start process: starting the vehicle; 3, a discharging process, wherein parameter information is recorded while vehicle acceleration operation is carried out; and step 4, obtaining a low-temperature discharge capability result of the new energy vehicle. According to the method, the low-temperature discharge capacity of the new energy automobile can be reliably judged, the use reliability of the automobile in a cold region is improved, automobile enterprises can conveniently verify the related performance of the automobile, and more accurate automobile use instructions can be edited according to the verification result.

    本发明揭示了一种判定新能源汽车低温放电能力的方法,包括以下步骤:步骤1、侵车过程:让车辆在设定温度充分降低温度;步骤2、冷启动过程:启动车辆;步骤3、放电过程:进行车辆加速操作的同时,记录参数信息;步骤4、得出新能源汽车低温放电能力结果。本发明能够可靠的判定新能源汽车低温放电能力,提升了汽车在寒冷地区使用的可靠性,也方便车企验证车辆相关性能,并能依此编辑更为准确的车辆使用说明。
