摘要

针对电池荷电状态过低和燃料电池功率变化对能源系统寿命的影响，设计了一种基于加装燃料电池动力系统的增程燃料电池汽车的多模式能量管理控制策略。该策略可以控制车辆根据电池荷电状态和车辆运行状况的变化，在功率跟随和多点恒温控制方式之间自动切换。仿真结果表明，所设计的控制策略能有效避免对能源系统寿命的破坏，使燃料电池工作点保持在较高效率区域内。

Research on the Energy Management Strategy of Range Extended Fuel Cell Electric Vehicle

Aiming at the influence of too low SOC of battery and fuel cell power change on the life of energy source system, a kind of multi-mode energy management control strategy was designed based on an extended-range fuel cell vehicle equipped with a fuel cell-battery power system. The strategy can control the vehicle to switch automatically between power following and multi-point thermostat control methods according to changes of battery SOC and vehicle operation condition. Simulation results show that the designed control strategy can effectively avoid the damage to the life of the energy source system and keep the fuel cell operating points within the higher efficiency area.
