Energy Management Method for Diesel Hydrogen Hybrid Vehicles andEvaluation of Renewable Energy Applications

How to maximize the use of renewable energy to achieve the most efficient utilization of energy resources is increasingly drawing attention.Against this backdrop, this study proposes a rule-based energy management strategy optimized by the Sparrow Search Algorithm for a novel diesel-hydrogen hybrid power system, investigating the impact of varying power source limits through simulation.The findings demonstrate that controlling the diesel engine power limit to 40-45 kW and the fuel cell power limit to 5-10 kW maximizes the renewable energy proportion and achieves significant energy conservation, establishing an optimal balance between sustainability and dynamic performance
