The application provides a
power output method and device of a
hydrogen hybrid vehicle, a medium and a vehicle, and belongs to the technical field of
hydrogen hybrid vehicles. The method comprises the following steps: obtaining a current SOC value of a
power battery and a current vehicle demand power; obtaining a
weight coefficient corresponding to the current SOC value and the current vehicle demand power respectively; and outputting the current available power of the
hydrogen fuel
cell after weighting based on the
weight coefficient corresponding to the current SOC value and the current vehicle demand power respectively. According to the embodiment of the application, the current available power of the
hydrogen fuel cell can be adjusted to a suitable position according to the actual demand of the vehicle on the basis of the current SOC value of the
power battery and the comprehensive consideration of the current vehicle demand power, so that the
hydrogen fuel cell can adapt to the variable dynamic
power demand of the vehicle, and the demand of the vehicle for the output capacity and the power of the
power battery is reduced, thereby reducing the vehicle cost and operation and maintenance cost while meeting the
power demand of the vehicle.
