The invention relates to the technical field of fuel cell vehicles, in particular to an energy management method and system for a dynamic variable-load fuel cell vehicle, equipment and a medium. The method comprises the steps that a power battery is started, the power battery is controlled to respond to the whole vehicle demand power, and the output power and the charge capacity of the power battery are monitored; the output power of the fuel cell and the output power of the power cell are allocated, and when the output power or the charge capacity of the power cell cannot meet the required power of the whole vehicle, the fuel cell is controlled to respond to the required power of the whole vehicle and charge the power cell; and the output power flow direction of the fuel cell and the output power linear change of the fuel cell are controlled according to the vehicle demand power change and the current charge capacity of the power cell. On the basis of dynamic variable load adjustment, the required power of the whole vehicle is reasonably distributed, the required power of the whole vehicle is met, the dynamic property of the fuel cell vehicle is guaranteed, and the durability and the service life of the fuel cell can be effectively prolonged.
