The invention relates to a power distribution method and device of a hybrid power vehicle and the vehicle, and belongs to the field of hybrid power vehicles. The method comprises the step of distributing output power of a power battery and a fuel battery according to the required power of the whole vehicle under the condition that a residual electric quantity is within a preset electric quantity range so that the residual electric quantity of the power battery approaches an expected electric quantity value within the preset electric quantity range. According to the power distribution method provided by the embodiment of the invention, an overcharge or overdischarge frequency of the power battery can be reduced, a service life of the power battery is prolonged, and the power distribution ismore reasonable.
