The invention provides a power control method of an automobile range extender, which comprises the following steps: four working intervals of a power battery are set, the SOC value of the first working interval is 20%-100%, the SOC value of the second working interval is 15%-20%, the SOC value of the third working interval is 10%-15%, and the SOC value of the fourth working interval is 0%-10%; dividing an output power interval of the range extender according to the working interval of the power battery, and enabling each working interval to correspond to the output power interval of one range extender; and obtaining the current SOC value of the power battery, and controlling the output power of the range extender according to the current SOC value. The use efficiency of the range extender can be improved, and the service life of the power battery is prolonged.

    本发明提供一种汽车增程器的功率控制方法,包括:设置动力电池的四个工作区间,第一工作区间的SOC值为20%~100%,第二工作区间的SOC值为15%~20%,第三工作区间的SOC值为10%~15%,第四工作区间的SOC值为0%~10%;根据动力电池的所述工作区间划分增程器的输出功率区间,使每一个所述工作区间与一个增程器的所述输出功率区间相对应;获取动力电池的当前SOC值,并根据所述当前SOC值控制增程器的输出功率。本发明能提高增程器的使用效率,增加动力电池的使用寿命。
