The invention provides an energy management method of a vehicle, a control unit, the vehicle and a medium. The method comprises the steps of firstly determining a destination of the vehicle; according to the position and the destination of the vehicle, obtaining a predicted energy consumption demand; if the destination is the hydrogen adding address, whether the vehicle is controlled to enter a hydrogen priority mode or not is determined based on the current hydrogen energy and predicted energy consumption requirements of the vehicle; and if the destination is the charging address, whether the vehicle is controlled to enter an electricity priority mode or not is determined based on the current electric energy and the predicted energy consumption demand of the vehicle. When hydrogenation is carried out, a fuel cell supplies power to the whole vehicle, residual energy of the fuel cell is converted into electric energy as much as possible to be stored in a high-voltage battery, and it can be guaranteed that the energy stored in a hydrogen tank and the energy stored in the high-voltage battery are both high after hydrogenation is completed, so that the actual endurance mileage after hydrogenation is closer to the maximum endurance mileage; during charging, the hydrogen energy of the fuel cell is reserved as much as possible, and the actual endurance mileage can also be improved.

    本发明提供了一种车辆的能量管理方法、控制单元、车辆及介质,首先确定车辆的目的地;然后根据车辆的位置与目的地,获得预计能耗需求;若目的地为加氢地址,则基于车辆的当前氢能和预计能耗需求,确定是否控制车辆进入氢优先模式;若目的地为充电地址,则基于车辆的当前电能和预计能耗需求,确定是否控制车辆进入电优先模式。通过在前往加氢时,以燃料电池向整车供电,并尽可能的将燃料电池的剩余能源转化为电能存储到高压电池中,在加氢完毕后就能保证氢罐和高压电池的存储能源均较高,从而使加氢后的实际续航里程更接近最大续航里程,同理,在前往充电时,尽可能的保留燃料电池的氢能,同样能够提高实际续航里程。
