Problems solved by technology

[0004] At present, most ships that use natural gas use dual-fuel internal combustion engines to burn natural gas, either using dual-fuel generators to convert it into electrical energy, or using dual-fuel main engines to directly drive propellers. The system design is complex and the energy efficiency is not high.

Abstract

The invention relates to a fuel cell and storage battery combined ship electric propulsion system, which comprises an LNG (Liquefied Natural Gas) fuel cabin, a gasification device, a heating device, a fuel cell, a storage battery, a distribution board, an electric propulsion motor, a reduction gear box, a shaft system and a propeller, the storage battery supplies power to the electric push motor through the distribution board, and the electric push motor drives the propeller to rotate through the reduction gearbox and the shafting. By means of the electric propulsion system, direct conversion from natural gas to electric energy can be achieved, the energy conversion efficiency is improved, energy is stored through the storage battery, storage of the electric energy is ensured, efficient conversion from electric energy to kinetic energy can be achieved through the electric propulsion motor, and the ship has better maneuverability.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a ship electric propulsion system and method combined with a fuel cell and a storage battery. Background technique [0002] In the context of increasingly stringent global emissions, more and more ships choose clean energy as their power source. Natural gas, as a clean energy source, is also increasingly used in ship propulsion systems. How to efficiently convert natural gas into ship kinetic energy is a key issue. It is the frontier subject of current ship power system research. [0003] Patent No. CN205113674U discloses a ship electric propulsion device and ship with full-turn rudder propellers. The ship electric propulsion device with a full-turn rudder propeller includes: a power station system, a propulsion motor system and a rudder propeller system; the power station system includes a generator set and a switchboard, and the power output end of the generator set is c...
