The invention discloses a dynamic power distribution method and device for a fuel cell vehicle, and belongs to the field of fuel cell vehicle energy control. The dynamic power distribution method for the fuel cell vehicle comprises the following steps: acquiring a battery charge state value of a power battery and performing interval division; calculating according to the working condition mileage data, the altitude difference data and the slope angle data to obtain a first required power of the fuel cell vehicle, and updating the required power according to a state interval of a power battery to obtain a second required power of the fuel cell vehicle; and updating the required power of the fuel cell vehicle by combining with the state interval of the power cell, and finally distributing the power through a fuel cell output table. Through the data closely related to the actual road working condition and the state interval of the power battery, the power required by the fuel cell vehicle is optimized and regulated, so that the obtained power required by the fuel cell vehicle is more accurate and better conforms to the actual road working condition.
本发明公开了一种燃料电池汽车动态功率分配方法及装置,属于燃料电池汽车能量控制领域。其中,一种燃料电池汽车动态功率分配方法包括:获取动力电池的电池荷电状态值并进行区间划分;之后根据工况里程数据、海拔高差数据和坡度角数据计算得到燃料电池汽车的第一需求功率,之后根据动力电池的状态区间更新需求功率,得到燃料电池汽车的第二需求功率;通过与动力电池的状态区间相结合更新燃料电池汽车的所需功率,最后通过燃料电池输出表对功率进行分配。通过与实际道路工况密切相关的数据以及动力电池的状态区间,对燃料电池汽车所需的功率进行优化调控,使得到的燃料电池汽车需求的功率更准确、更加的符合实际道路工况。
