The invention discloses an electricity-electricity hybrid power ship, which comprises a ship body, a propeller is arranged at the tail of the ship body, an electric energy storage unit composed of a group of lithium ion battery packs connected in parallel is arranged in the bottom of the ship body, and each lithium ion battery pack is connected with a relay. All the relays are consistent in specification and connected in parallel and then connected with a marine generator set through a charging controller with an external charging interface, a first straight wing propeller is sequentially connected with a first marine motor and a first motor controller, and a second straight wing propeller is sequentially connected with a second marine motor and a second motor controller. The first motor controller and the second motor controller are consistent in specification and are connected in parallel and then are connected with the electric energy storage unit through the inverter. The electric-electric hybrid power ship has the advantages that pollution is small, the draft depth is suitable for multiple characteristics of domestic rivers and shoals. Meanwhile, the straight wing propeller is adopted, and the electric-electric hybrid power ship has the advantages of integration of a rudder and the propeller, high energy conversion efficiency, strong controllability, good maneuverability and low cost.
