Optimization Path Analysis of Energy Management Strategy for Fuel Cell Heavy Trucks
With the development of the new energy vehicle industry,fuel cell heavy-duty trucks are increasingly receiving widespread attention from the industry and society.However,their energy utilization rate is relatively low,their economy is poor,and their ability management strategies are relatively backward.To this end,optimizing the energy management strategy of fuel cell heavy-duty trucks can improve their energy utilization efficiency and overall vehicle economy.Adopting a bidirectional full bridge DC/DC converter as part of the system control,and using traditional phase-shifting control forward working mode for energy transfer.Optimization analysis was conducted on the energy management strategy of fuel cell heavy-duty trucks,and a layered energy management strategy was designed to improve the overall performance of the system through coordinated control and energy management.Finally,a vehicle model was built using Cruise software and common operating conditions such as urban,suburban,and high-speed were simulated.The results showed that the proposed layered energy management strategy can significantly improve the energy efficiency of fuel cell heavy-duty trucks and reduce operating costs,providing feasible technical support for the promotion and application of fuel cell heavy-duty trucks.
