The invention relates to the technical field of fuel cells, and discloses a fuel cell hybrid power system power distribution control method and system and a vehicle. The method comprises the steps of when the whole vehicle is in a driving state, according to the value of the SOC of the current power battery, the obtained average discharge capacity and discharge time of the power battery in the previous driving state and the obtained average charge capacity and charge time of the power battery in the previous braking state, the output power of the fuel battery is adjusted according to a preset method, so that the SOC of the power battery is in a normal use range. When the whole vehicle is in the driving state, the output power of the fuel cell can be adjusted through the preset method, so that the SOC of the power cell is in the normal use range. Therefore, the phenomenon that the power of the fuel cell is in an extreme value due to the fact that the SOC of the power cell is increased in the power correction process of the fuel cell can be prevented, and the service life of the fuel cell is guaranteed.

    本发明涉及燃料电池技术领域,公开了一种燃料电池混合动力系统功率分配控制方法、系统及车辆,该方法包括在整车处于驱动状态下,根据当前动力电池的SOC的值、以及获取的上一驱动状态的动力电池平均放电量以及放电时间、上一制动状态的动力电池平均充电量以及充电时间,按照预设方法调整燃料电池的输出功率,以使动力电池的SOC处于正常使用范围。由于当整车处于驱动状态时,能够通过预设方法调整燃料电池的输出功率,以使动力电池的SOC处于正常使用范围。因此,能够防止在对燃料电池的功率修正过程中,因动力电池的SOC升高导致燃料电池功率处于极值的现象的发生,从而保障了燃料电池的使用寿命。
