The invention discloses a vehicle composite energy management method, device and equipment and a storage medium, and the method comprises the steps: judging whether a fuel cell system is started or not according to a preset switch control rule, and taking the whole vehicle demand power and the battery charge state of a power battery under different working conditions of a current vehicle as the input result of the fuel cell system; when it is judged that the fuel cell system is started, fuzzy output power is obtained through fuzzy control calculation, an input result is smoothed through a moving average filter, smooth output power is obtained, and the fuel cell system is controlled to output the smooth output power; when it is judged that the fuel cell system is closed, the fuel cell system is controlled to be closed, overcharge of the power cell can be avoided, large fluctuation of output power of the fuel cell is avoided, the method can adapt to various complex working conditions, economical efficiency of the hybrid electric vehicle is guaranteed, durability of the fuel cell is improved, safety of the power cell is improved, and the service life of the power cell is prolonged.

    本发明公开了一种车辆复合能量管理方法、装置、设备及存储介质,所述方法通过根据预设开关控制规则判断燃料电池系统是否开启,将当前车辆不同工况下的整车需求功率和动力电池的电池荷电状态作为燃料电池系统的输入结果;在判定燃料电池系统开启时,通过模糊控制计算获得模糊输出功率,通过滑动平均滤波器对输入结果进行平滑处理,获得平滑输出功率,控制燃料电池系统输出平滑输出功率;在判定燃料电池系统关闭时,控制燃料电池系统关闭,能够避免动力电池过充,避免了燃料电池输出功率大幅度波动,能够适应各种复杂工况,保证了混合动力汽车的经济性,提高了燃料电池的耐久性,提升了动力电池的安全性及寿命。
