Abstract: The development of ship electric propulsion technology poses new challenges for ship energy storage, ship intelligence and electrification. The application of clean new energy represented by lithium battery will drive the technological innovation of green ships and smart ships. The marine power battery system is the core of the electric ship power system, and its control and monitoring technology affects the safety of ship control, operation and maintenance. In view of the fact that modern ships have many cabins and complicated pipelines, CAN bus technology was introduced to develop marine power battery control system, and based on this, the modular control strategy of marine power battery system was designed from shore charging, power storage to power output. Finally, the battery management system was used as the core for system integration, and the integrated management of the marine power battery system was completed. The practical application shows that the proposed method is effective for the effective management of the operation and maintenance of the marine power battery system.
