The invention relates to the technical field of vehicles, and discloses an energy management method of a fuel cell vehicle and the fuel cell vehicle, the energy management method of the fuel cell vehicle needs to judge whether an initial SOC value is smaller than an initial preset SOC value or not, if yes, a fuel cell engine is started, and if not, the fuel cell engine is not started. Secondly, in the heavy load state, when the real-time SOC value is increased to the first preset SOC value and kept for the first preset time, the fuel cell engine is turned off, and when the real-time SOC value is reduced to the second preset SOC value and kept for the second preset time, the fuel cell engine is started. And in the light load state, when the real-time SOC value is increased to a third preset SOC value, the fuel cell engine is shut down, and when the real-time SOC value is reduced to a fourth preset SOC value, the fuel cell engine is started. The light load and the heavy load are distinguished, and the SOC preset value and the preset time are combined, so that the start-stop times and the high-power working probability of the fuel cell can be reduced, and the service life is prolonged.
本发明涉及车辆技术领域,公开一种燃料电池车辆的能量管理方法及燃料电池车辆,燃料电池车辆的能量管理方法需先判断初始SOC值是否小于初始预设SOC值,若是,启动燃料电池发动机,若否,不启动燃料电池发动机。其次,在重载状态下,当实时SOC值提升至第一预设SOC值并保持第一预设时间,关闭燃料电池发动机,实时SOC值降低至第二预设SOC值并保持第二预设时间时,启动燃料电池发动机。在轻载状态下,当实时SOC值提升至第三预设SOC值,关闭燃料电池发动机,实时SOC值降低至第四预设SOC值,启动燃料电池发动机。区分轻载和重载并结合SOC预设值、预设时间,可减少燃料电池的启停次数、高功率工作几率,提高使用寿命。
