The invention relates to a hydrogen fuel cell vehicle power distribution optimization method and device, and belongs to the technical field of hydrogen fuel cell vehicle power distribution.The method comprises the steps that demand power at the current moment is obtained; determining the life cycle stage of the hydrogen fuel cell engine according to the operation data of the hydrogen fuel cell engine; determining a hydrogen fuel cell engine power sequence and a power cell power sequence according to the hydrogen fuel cell engine power range, the maximum power change rate and the SOC threshold; and according to the hydrogen fuel cell engine power sequence and the power cell power sequence, carrying out demand power distribution. In the initial stage of the hydrogen fuel cell engine, the hydrogen fuel cell engine can operate in a wider power range, and in the middle stage or the last stage of the life cycle of the hydrogen fuel cell engine, the hydrogen fuel cell engine is limited in a narrower power range, so that the service life of the hydrogen fuel cell engine is prolonged.

    本发明涉及一种氢燃料电池车辆功率分配优化方法及装置,属于氢燃料电池车辆功率分配技术领域,所述方法包括:获取当前时刻的需求功率;根据氢燃料电池发动机的运行数据,确定氢燃料电池发动机所处的生命周期阶段;根据所述氢燃料电池发动机功率范围、所述最大功率变化率以及所述SOC阈值,确定所述氢燃料电池发动机功率序列和动力电池功率序列;根据所述氢燃料电池发动机功率序列和动力电池功率序列,进行需求功率分配。本发明在氢燃料电池发动机初期阶段,氢燃料电池发动机能够在较宽泛的功率范围内运行,而在氢燃料电池发动机的生命周期中期或末期阶段,氢燃料电池发动机被限制在较窄的功率范围,以利于延长氢燃料电池发动机的使用寿命。
