Abstract

The fuel cell-battery hybrid ship uses fuel cells as the main power source and batteries as the auxiliary power source. For hybrid power systems, an energy management strategy (EMS) is needed to allocate the output power of each power source. In order to improve hydrogen fuel economy and system life, an external energy efficiency maximization strategy based on power decoupling is proposed for simulation analysis, and compare with the dual closed-loop PI control strategy and the traditional external energy efficiency maximization strategy (EEMS) to verify its effectiveness. The results show that the proposed strategy can meet the power requirements of ships under typical working conditions, effectively reduce hydrogen fuel consumption, and increase the utilization rate of batteries, thereby using the characteristics of hybrid power systems to improve hydrogen fuel economy and make the entire system able to run efficiently overall.
