The invention particularly relates to an underwater vehicle multi-energy hybrid energy storage system and a coordinated energy management strategy. The system comprises a lithium ion battery, a super capacitor and a fuel cell applying a proton exchange membrane which are respectively connected to a direct current bus. The method for coordinating the energy management strategy comprises the following steps: acquiring a current motion parameter and a current energy parameter of an underwater vehicle; inputting the current motion parameter, the current energy parameter and the expected navigational speed into a load prediction model based on a BP neural network, and estimating the expected total power at the next moment; and determining a corresponding action strategy according to the current operation mode of the underwater vehicle, and performing power distribution on the expected total power based on the action strategy. According to the scheme, the hybrid energy system can perform smooth working mode switching and optimal power distribution under different working conditions.
