The invention discloses a fuel cell vehicle energy management control method, which comprises the following steps: setting a vehicle energy management mode associated with the output power of a fuel cell system, the vehicle energy management mode comprising an EV mode, an unbalanced mode and a balanced mode; after the vehicle is powered on, the SOC of the power battery is detected in real time, and the type of the whole vehicle energy management mode is determined according to the SOC of the power battery; and controlling the whole vehicle to be switched among different energy management modes based on the change of the SOC of the power battery. The change state of the SOC of the power battery can be accurately controlled, so that the power output of the fuel battery system is indirectly controlled, the use requirement of the whole vehicle is met, and the economical efficiency of the whole vehicle is improved.

    本发明公开了一种燃料电池整车能量管理控制方法,设置与燃料电池系统输出功率相关联的整车能量管理模式,整车能量管理模式包含EV模式、非平衡模式和平衡模式;车辆上电后,实时检测动力电池SOC,根据动力电池SOC确定整车能量管理模式的类型;基于动力电池SOC的变化控制整车在不同能量管理模式之间进行切换。本发明能够精确控制动力电池SOC的变化状态,进而间接控制燃料电池系统的功率输出,从而满足整车使用需求并提高整车的经济性。
