The invention discloses a fuel cell automobile energy management method, device and equipment and a medium, and belongs to the technical field of fuel cell automobiles. The method comprises the steps that the load current of the automobile, the charge state of the super capacitor and the first filtering frequency of the fuel cell are obtained; determining a second filtering frequency of the storage battery according to the load current and the charge state; and according to the load current, the state of charge, the first filtering frequency and the second filtering frequency, determining currents output by the fuel cell, the storage battery and the super capacitor respectively. According to the method, the filtering frequency corresponding to the storage battery can change along with the change of the load current and the charge state of the super-capacitor, the characteristics of three kinds of energy can be more fully utilized, energy distribution among the power supply units is more reasonable, and the overall performance and the working efficiency of the vehicle are improved.

    本发明公开了一种燃料电池汽车能量管理方法、装置、设备及介质,属于燃料电池汽车技术领域。该方法包括:获取汽车的负载电流、所述超级电容的荷电状态和所述燃料电池的第一滤波频率;根据所述负载电流和所述荷电状态,确定所述蓄电池的第二滤波频率;根据所述负载电流、所述荷电状态,所述第一滤波频率和所述第二滤波频率,确定所述燃料电池、所述蓄电池和所述超级电容三者分别输出的电流。该方法中蓄电池对应的滤波频率会随着负载电流和超级电容的荷电状态的变化而变化,可以更加充分利用三种能源的特性,使得各个供电单元间能量的分配更合理,提高了车辆的整体性能和工作效率。
