The invention provides a fuel cell vehicle energy management control method and a fuel cell vehicle, belongs to the technical field of fuel cells, and solves the problem that an existing energy management control strategy is not suitable for variable operation conditions. The method comprises the following steps: when the fuel cell runs, identifying a section where the SOC of the power cell is located in real time, and controlling the fuel cell to output power matched with the section; counting the following parameters under the current working condition once every T time, including the running time of the fuel cell under each output power, the on-off times of the fuel cell and the skipping times of the fuel cell from one output power to another output power; and identifying the output power of the fuel cell corresponding to the longest operation time, and finely adjusting the output power according to the startup and shutdown times and the related jump times so as to control the output of the fuel cell in the next time T. According to the method, the output power of the fuel cell is adaptively adjusted based on the operation condition, and the startup and shutdown times and the variable load times are reduced.

    本发明提供了一种燃料电池车辆能量管理控制方法及燃料电池车辆,属于燃料电池技术领域,解决了现有能量管理控制策略不适用于多变的运行工况的问题。该方法包括:在燃料电池运行时,实时识别动力电池的SOC所处区段,控制燃料电池输出与该区段匹配的功率;每隔T时间进行一次当前工况下如下参数的统计,包括燃料电池在各输出功率下的运行时间、燃料电池开关机次数、燃料电池从一输出功率跳转至另一输出功率的跳转次数;识别最长运行时间对应的燃料电池输出功率,根据开关机次数、相关的跳转次数对该输出功率进行微调,以控制下一时间T内燃料电池的输出。该方法基于运行工况对燃料电池输出功率进行自适应调节,减少了开关机次数和变载次数。
