The invention relates to a hydrogen fuel electric vehicle energy management method capable of prolonging the service life of a hydrogen fuel cell, and belongs to the technical field of new energy vehicle control. Determining a hydrogen fuel cell engine power sequence and a power cell power sequence; determining a real hydrogen consumption sequence of the hydrogen fuel cell engine and an equivalent hydrogen consumption sequence of the power cell according to the hydrogen fuel cell engine power sequence and the power cell power sequence; weighting the real hydrogen consumption sequence to obtain a weighted hydrogen consumption sequence; and carrying out demand power distribution according to the weighted hydrogen consumption sequence and the equivalent hydrogen consumption sequence. Through the calculation method of weighting the real hydrogen consumption, the working interval distribution of the hydrogen fuel cell power can be optimized, and the time proportion of operation in the low-life power interval is reduced, so that the service life of the hydrogen fuel cell is prolonged.

    本发明涉及一种延长氢燃料电池寿命的氢燃料电动车能量管理方法,属于新能源车辆控制技术领域,所述管理方法包括:根据需求功率、氢燃料电池发动机功率范围和最大功率变化率,确定氢燃料电池发动机功率序列以及动力电池功率序列;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,确定氢燃料电池发动机的真实氢耗序列和动力电池的等效氢耗序列;对真实氢耗序列加权处理得到加权氢耗序列;根据所述加权氢耗序列和所述等效氢耗序列进行需求功率分配。本发明通过加权真实氢耗的计算方法,能够优化氢燃料电池功率的工作区间分布,减少在低寿命功率区间运行的时间占比,从而提高氢燃料电池使用寿命。
