The invention discloses a power source electric energy recycling system and method for an oil-electricity dual-drive ship. An output shaft of a diesel engine is connected with a steering oar; a rotor shaft of the propulsion motor is connected with the steering oar; the battery pack first interface is connected with charging equipment, and the battery pack second interface is connected with the propulsion motor through the power control module; the voltage-sharing module is indirectly connected with the battery pack to balance the voltage of each battery pack in the battery pack, and a voltage detection unit is arranged on the voltage-sharing module. In the working mode of the diesel engine, when the load rate of the diesel engine is smaller than 85%, the diesel engine is controlled to drive the propulsion motor to operate and generate electricity through the gear reducer; the feed charges the battery pack; and according to the voltage difference between the main rechargeable battery E2 and the battery pack, the boost ratio of the voltage equalizing module is adjusted, and the voltage on each battery pack is equalized through the voltage equalizing module. The lithium battery is charged through the redundant capacity of the generator set, so that the power source of the oil-electricity dual-drive ship is recycled, and the cruising ability is improved.
