The invention discloses a manta ray imitating submersible multi-source energy harvesting-distributed energy storage system and method, and belongs to the technical field of underwater energy systems. The method specifically comprises the steps that the actual power of the manta ray imitating submersible is monitored through a battery management system, and the current working mode is judged; switching a corresponding energy harvesting mode according to the current working mode; analyzing the power distribution of each lithium battery pack of the manta ray-simulated submersible in real time through a BMS, selecting the lithium battery pack with the lowest state of charge, and preferentially charging the lithium battery pack; arranging the single lithium batteries in the selected battery pack from low to high according to the state of charge, and sequentially charging the lithium batteries according to a distributed storage strategy of charging first with low power; and the overall efficiency of the lithium battery pack is evaluated through the BMS, and charging is stopped after the multi-mode working requirement of the next period is met. Through solar energy, ocean current energy and temperature difference energy harvesting of the submersible in multiple modes and in combination with a low-electricity first-charging distributed energy storage technology, the goals of efficient energy supply and long-time self-sustaining work of the manta ray imitating submersible are achieved.
