The invention provides a power distribution method for a power supply based on the running state of a hybrid electric vehicle, the running state of the hybrid electric vehicle is divided into five working conditions of starting acceleration, acceleration, driving, deceleration and braking, and the power supply modes of the power supply comprise lithium battery power supply, hydrogen fuel cell system power supply and hydrogen fuel cell system and lithium battery hybrid power supply. The method comprises the following steps: determining a power supply mode by adopting a power supply mode switching strategy according to the running state of the hybrid electric vehicle and the required power of the whole vehicle, which are acquired in real time, and determining real-time output power values output by a hydrogen fuel cell system and a lithium battery by adopting a power distribution strategy, therefore, the output power of the hydrogen fuel cell system and the lithium battery is controlled to meet the required power of the whole vehicle, and the energy distribution of the hydrogen fuel cell system and the lithium battery is realized. The power supply mode switching strategy and the power distribution strategy are integrated, the method can be applied to power distribution of the power supply of the hybrid electric vehicle, and the power performance of the whole vehicle is improved.
