The invention provides a control method, device and equipment for the state of charge of a vehicle battery, and the method comprises the steps: obtaining the current state of charge of a power battery system of a vehicle under the condition that the vehicle is started; judging whether the current state of charge is greater than a preset state of charge determined according to the battery temperature in the power battery system, and obtaining a first judgment result; controlling the power state of the vehicle according to the first judgment result; wherein the power state is a power matching state of a range extender and a power battery system of the vehicle. According to the embodiment of the invention, the power matching state of the range extender and the power battery system is controlled according to the magnitude relationship between the current state of charge of the power battery system of the vehicle and the preset state of charge determined according to the battery temperature in the power battery system, so that the two kinds of power energy of the extended-range electric vehicle are reasonably matched for use; the energy consumption can be saved, the vehicle using cost is reduced, the battery can be used more safely and reasonably, the battery safety is improved, and the battery service life is prolonged.

    本发明提供一种车辆电池荷电状态的控制方法、装置及设备,其中,包括:在车辆启动的情况下,获取车辆的动力电池系统的当前荷电状态;判断当前荷电状态是否大于根据动力电池系统中的电池温度确定的预设荷电状态,获取第一判断结果;根据第一判断结果,控制车辆的动力状态;其中,动力状态为车辆的增程器和动力电池系统的功率匹配状态。本发明实施例根据车辆的动力电池系统的当前荷电状态与根据动力电池系统中的电池温度确定的预设荷电状态的大小关系,控制增程器和动力电池系统的功率匹配状态,从而将増程式电动汽车的两种动力能源合理匹配使用,能够节省能耗,降低用车成本,同时还能更安全更合理使用电池,提升电池安全性及电池寿命。
