The invention discloses a range extender power control method and device and a computer readable storage medium. The method comprises the steps that the current working mode of a whole vehicle, the current remaining electric quantity of a power battery and the electric quantity change trend are obtained; determining preset output power in a preset output power set based on the residual electric quantity and the electric quantity change trend; determining the generated power of the range extender according to the working mode and the preset output power; and controlling the range extender to output the generated power. Due to the fact that the generated power of the range extender under different residual electric quantities and different electric quantity change trends can be determined in different whole vehicle working modes, the corresponding power requirements of the motor in different working states are met, the problem that the fuel economy of the range extender is low due to the fact that single output power is adopted in any working state is solved, and the service life of the range extender is prolonged. The fuel economy of the range extender is improved, and the energy-saving effect is achieved.

    本发明公开了增程器功率控制方法、设备及计算机可读存储介质,该方法包括:获取当前整车的工作模式、动力电池当前的剩余电量和电量变化趋势;基于所述剩余电量和所述电量变化趋势,在预设输出功率集合中确定预设输出功率;根据所述工作模式和所述预设输出功率确定增程器的发电功率;控制所述增程器输出所述发电功率。由于能够在不同整车工作模式下,确定不同剩余电量和电量变化趋势下的增程器发电功率,从而满足电机在不同工作状态下对应的功率需求,避免任何工作状态均采用单一的输出功率导致的增程器燃油经济性低的问题,提高了增程器的燃油经济性,起到节能的效果。
