摘　　要：汽车能耗和排放污染问题近年来已引起广泛关注,以氢气为燃料的燃料电池汽车是实现近零排放的可行途径。在燃料电池混合动力客车中,整车经济性和燃料电池发动机的耐久性及可靠性在很大程度上取决于整车能量管理策略的优劣。对能量混合型燃料电池城市客车基于电压控制的能量管理策略和基于电流控制的能量管理策略进行讨论,由于蓄电池输出电流对总线电压的变化敏感,使得基于电压控制的能量管理策略在实际中应用效果并不理想,而基于电流控制的能量管理策略更适合能量混合型燃料电池城市客车。基于电流控制的能量管理策略包括能量分配和动态滤波两个部分,这种策略构成能够保证燃料电池发动机平稳运行和蓄电池组的合理使用。道路试验结果表明,基于电流控制的能量管理策略很大程度改善了整车经济性和可靠性。The problem of vehicle energy consumption and exhaust pollution has caused wide public concern over recent years, and the use of hydrogen fuel has been repeatedly demonstrated to be a viable approach to achieving near-zero emission from fuel cell vehicle. In fuel cell hybrid electric bus, the fuel economy and the durability and reliability of fuel cell engine depend largely on the complete vehicle energy management strategy. The energy management strategy based on voltage control is compared with the energy management strategy based on current control. The comparison result shows that the latter strategy is more suitable for the energy hybrid bus, because battery current is sensitive to bus voltage variation. In order to ensure the optimal operation of fuel cell engine and battery sets, energy distribution and dynamic filtering methods are included in the energy management strategy based on current control. Finally road test results show that complete vehicle fuel economy and reliability have been greatly improved.
