The invention discloses a range extender control method, device and equipment and a medium, and the method comprises the steps: correcting a preset SOC value according to the temperature of a battery cell and/or the service life of a battery, and obtaining a target SOC value; and controlling a range extender of the vehicle according to the target SOC value. The preset SOC value is corrected by combining the temperature of the battery cell and/or the service life of the battery to obtain the target SOC value, and finally the range extender of the vehicle is controlled according to the target SOC value, so that the purpose of reducing the starting failure risk of the range extender in a low-temperature environment is achieved, the starting reliability of the range extender is improved, and the starting time of the range extender is shortened. And meanwhile, over-discharge and over-charge of the battery can be prevented, so that the service life of the battery is prolonged, and the problem that the range extender is easy to fail to start in a low-temperature environment in the prior art is effectively solved.

    本发明公开一种增程器控制方法、装置、设备和介质,所述方法包括:根据电池电芯的温度和/或电池的使用寿命对预设SOC值进行修正,获得目标SOC值;根据所述目标SOC值对车辆的增程器进行控制。本发明通过结合电池电芯的温度和/或电池的使用寿命对预设SOC值进行修正,获得目标SOC值,最后根据所述目标SOC值对车辆的增程器进行控制,实现了降低在低温环境下增程器启动失败风险的目的,提高了增程器启动的可靠性,同时可预防电池过放、过充,进而有利于延长电池的使用寿命,有效地解决了现有技术中在低温环境下增程器容易启动失败的问题。
