The invention discloses an equivalent hydrogen consumption minimum-based energy management method for a hydrogen fuel cell vehicle. The method comprises the following steps: acquiring SOC of a battery in the hydrogen fuel cell vehicle and vehicle load demand power Pload in real time; taking the SOC of the storage battery and the load demand power Pload as input quantities and inputting the input quantities into a preset objective function for equivalent hydrogen consumption calculation; performing multivariable constrained optimal value solution on the target function according to a set constraint condition to obtain the lithium battery power and the fuel battery power when the equivalent hydrogen consumption is minimum, and performing power control according to the lithium battery power and the fuel battery power when the equivalent hydrogen consumption is minimum. The method has the advantages that the fuel cell power and the power cell power of the fuel cell hybrid power system are subjected to power distribution, the optimal selection of fuel cell energy management is realized, the cruising ability is increased, and the fuel economy is realized; the minimum hydrogen consumption under the same condition is achieved, and fuel economy is achieved.
