The invention relates to the field of new energy vehicles, in particular to a range extender system for a pure electric commercial vehicle and a control method of the range extender system. The range extender system comprises an engine, an engine controller, a generator, a generator controller, a high-voltage distribution box and a range extender controller, and the generator controller controls the rotating speed of the generator according to the obtained real-time voltage of the direct-current high-voltage bus of the battery pack so as to supply power to the pure electric commercial vehicle. According to the range extender system for the pure electric commercial vehicle and the control method of the range extender system, the range extender system is configured for the pure electric commercial vehicle, the endurance mileage of the pure electric commercial vehicle is increased, and the time cost and the money cost are saved; meanwhile, the function of supplying power to the pure electric commercial vehicle is achieved by only obtaining the voltage of the direct-current high-voltage bus of the battery pack, data obtaining and modification of the pure electric commercial vehicle are reduced, and the convenience of additionally installing the range extender system is improved.

    本发明涉及新能源汽车领域,特别是涉及一种用于纯电动商用车的增程器系统及其控制方法。所述增程器系统包括发动机、发动机控制器、发电机、发电机控制器、高压配电盒、增程器控制器,其中,所述发电机控制器依据获取到的所述电池包的直流高压母线实时电压,控制所述发电机的转速以为所述纯电动商用车供电。上述用于纯电动商用车的增程器系统及其控制方法,通过给纯电动商用车配置一套增程器系统,提升了纯电动商用车的续航里程,节省了时间成本及金钱成本;同时,通过只获取电池包的直流高压母线电压实现为纯电动商用车供电的功能,减少了数据获取及对纯电动商用车的改动,提高了加装增程器系统的便利性。
