摘要
随着新能源汽车产业的发展,燃料电池重卡越来越受到行业与社会的广泛关注,然而其能量利用率相对较低,经济性较差,能力管理策略相对落后.为此,通过优化燃料电池重卡的能量管理策略来提高其能量利用效率和整车经济性.采用双向全桥DC/DC变换器作为系统控制的一部分,并使用传统移相控制正向工作模式进行能量传输.对燃料电池重卡的能量管理策略进行了优化分析,设计分层能量管理策略,通过协调控制和能量管理来提高系统的整体性能.最后,利用Cruise软件搭建整车模型并设置城市、郊区和高速等常见工况进行仿真,结果表明所提出的分层能量管理策略可以显著提高燃料电池重卡的能耗效率,并降低使用成本,为燃料电池重卡的推广应用提供了可行的技术支持.
Abstract
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.
