The invention provides a control method and a control device of a range extender, a vehicle and a storage medium. The method comprises the following steps: acquiring battery end voltage, battery sustainable output power and actual power of a vehicle high-voltage load; if the battery end voltage is less than or equal to the first battery end voltage threshold, judging whether the battery end voltage is greater than a second battery end voltage threshold; wherein the first battery end voltage threshold value refers to the upper limit of the battery end voltage value for starting the range extender; the second battery end voltage threshold value refers to a battery end voltage value lower limit when the battery keeps running; if the battery end voltage is greater than the second battery end voltage threshold value, determining a first demand power of the range extender according to the battery sustainable output power, the actual power of the vehicle high-voltage load and the battery end voltage; and controlling the range extender to start according to the first required power. Therefore, over-discharge of the battery can be avoided, and the risk of over-low voltage of the battery can be reduced.

    本申请提供了一种增程器的控制方法、控制装置、车辆及存储介质,获取电池端电压、电池可持续输出功率和车辆高压负载的实际功率;若电池端电压小于等于第一电池端电压阈值,则判断电池端电压是否大于第二电池端电压阈值;其中,第一电池端电压阈值是指启动增程器的电池端电压值上限;第二电池端电压阈值是指电池维持运行的电池端电压值下限;若电池端电压大于第二电池端电压阈值,则根据电池可持续输出功率、车辆高压负载的实际功率和电池端电压,确定增程器的第一需求功率;按照第一需求功率控制增程器启动。这样,能够避免电池过度放电,降低出现电池端电压过低的风险。
