The invention provides a vehicle battery management method, a control unit, a vehicle and a medium, and the method comprises the steps: firstly, obtaining the current vehicle power, the residual electric energy of a high-voltage battery and the rest duration when the vehicle is parked; determining a target energy consumption demand of the vehicle according to the rest duration and the current vehicle power; and finally, according to the residual electric energy of the high-voltage battery and the target energy consumption demand, whether the vehicle is controlled to enter an electricity priority mode or not is judged. When the vehicle is parked and the user has a rest, a power priority mode is adopted for power supply, the working time of a high-voltage battery can be prolonged as much as possible in the rest process of the user, the working time of a fuel cell can be shortened as much as possible, and therefore noise in the vehicle in the rest process of the user is reduced.

    本发明提供了一种车辆电池管理方法、控制单元、车辆及介质,首先在车辆驻车时,获取当前车辆功率、高压电池的剩余电能和休息时长;然后根据休息时长和当前车辆功率,确定车辆的目标能耗需求;最终根据高压电池的剩余电能和目标能耗需求,判断是否控制所述车辆进入电优先模式。其中,在车辆驻车用户休息时,采用电优先模式供电,能够在用户休息过程中尽可能的增加高压电池的工作时长,减少燃料电池的工作时长,从而减小用户休息过程中车内噪音。
