The invention discloses an energy distribution control method of an electric-electric hybrid fuel cell vehicle. The energy distribution control method comprises the steps of in a vehicle running process, obtaining vehicle running parameters in real time, and determining the motor demand power, the maximum discharge power of a fuel cell and the maximum discharge power of a lithium battery according to the running parameters; determining the working mode of the motor according to the vehicle state, the motor demand power, the maximum discharge power of the fuel cell and the maximum discharge power of the lithium battery, and distributing the output power of the fuel cell and the lithium battery in real time according to the working mode of the motor. On the premise of ensuring safe operation of the fuel cell and the lithium battery, rapid power fluctuation of the fuel cell can be avoided, and the fuel cell is used as energy supply of a power system as far as possible, so that the fuel cell operates in a high-efficiency output interval as far as possible.

    本发明公开了一种电电混合燃料电池汽车的能量分配控制方法。车辆行驶过程中,实时获取车辆行驶参数,根据行驶参数确定电机需求功率、燃料电池最大放电功率和锂电池最大放电功率,根据车辆状态、电机需求功率与燃料电池最大放电功率和锂电池最大放电功率之间的大小关系确定电机的工作模式,根据电机的工作模式对燃料电池和锂电池的输出功率进行实时分配。能够在保证燃料电池、锂电池安全运行前提下,避免燃料电池功率快速波动,并尽可能利用燃料电池作为动力系统的能源供给,使得燃料电池尽可能运行在其高效率输出区间。
