The invention discloses a low-temperature starting method and system for an extended-range electric vehicle and the extended-range electric vehicle, and the method comprises the steps: obtaining the temperature information of the extended-range electric vehicle in response to a starting signal of the extended-range electric vehicle; whether the extended-range electric vehicle is in a low-temperature state or not is judged according to the temperature information; when the extended-range electric vehicle is in the low-temperature state, calculating logic used for calculating engine starting parameters is selected according to the actual vehicle speed of the extended-range electric vehicle, and the corresponding starting parameters are calculated according to the selected calculating logic; the engine is started according to the calculated starting parameters, so that the temperature of a power battery of the extended-range electric vehicle is indirectly increased by increasing the circulating water temperature of a water circulating pipe network; wherein the engine and the power battery share the water circulation pipe network.

    本发明公开了一种增程式电动车的低温启动方法、系统及增程式电动车,所述方法包括:响应于增程式电动车的启动信号,获取所述增程式电动车的温度信息;利用所述温度信息判断所述增程式电动车是否处于低温状态;当所述增程式电动车处于低温状态,根据所述增程式电动车的实际车速选择用于计算发动机启动参数的计算逻辑,并按照选择的计算逻辑计算对应的启动参数;按照计算出的所述启动参数启动所述发动机,以通过提升水循环管网的循环水温的方式间接提升增程式电动车的动力电池温度;其中,所述发动机和所述动力电池共用所述水循环管网。
