This paper presents an energy management strategy for hydrogen fuel cell railway vehicles equipped with a Hybrid Energy Storage System (HESS). The proposed strategy aims to optimize power distribution between the hydrogen fuel cell and the HESS components, which include a battery system and ultracapacitor, in order to minimize hydrogen consumption and enhance system efficiency under various operating conditions. By employing the Equivalent Consumption Minimization Strategy (ECMS) and adjusting the power allocation based on the vehicle's power demands, the strategy effectively manages the state of charge (SOC) of both the battery system and ultracapacitor. Simulation results demonstrate that the proposed algorithm improves the hydrogen consumption by approximately 20% compared to conventional rule-based algorithms while maintaining a higher battery SOC. Also the proposed energy management strategy not only improves fuel efficiency but also contributes to the extended lifespan of the battery system by prioritizing the use of ultracapacitor for high-frequency power demands. This research offers a valuable approach for enhancing the performance and efficiency of hydrogen fuel cell railway systems, making a significant contribution to the development of eco-friendly rail transport technology.
