The invention discloses a low-temperature working condition control method for an extended-range electric vehicle. The method comprises the steps that the electric quantity of a power battery, the battery temperature and the water temperature of an engine of the extended-range electric vehicle are monitored in real time; the use working condition and the driving intention of a driver are obtained, and whether the extended-range electric vehicle is in a low-temperature state or not is judged according to the electric quantity of the power battery, the battery temperature and the water temperature of the engine; and if yes, entering a low-temperature mode, and starting a battery water heater and a range extender engine so as to increase the battery temperature and the engine water temperature to a set range. The low-temperature acceleration performance and the fuel economy of the extended-range electric vehicle can be improved, and the comfort of NVH experience of passengers is improved.

    本发明公开了一种增程式电动汽车的低温工况控制方法,包括:实时监控增程式电动汽车的动力电池电量、电池温度和发动机水温;获取驾驶员的使用工况和驾驶意图,并根据所述动力电池电量、所述电池温度和所述发动机水温判断增程式电动汽车是否处于低温状态;如果是,则进入低温模式,启动电池水加热器和增程器发动机,以提升电池温度和发动机水温至设定范围。本发明能提高增程式电动车低温加速性能和燃油经济性,增加乘员的NVH体验的舒适性。
