The invention relates to a fuel cell automobile energy management method and system, and belongs to the technical field of battery energy management. Working condition data and vehicle average power when the vehicle travels on a set route are recorded in advance, before the vehicle travels on the same route again, the optimal power generation power is planned in a segmented mode in advance according to the SOC of the power battery at the moment so as to control the SOC of the battery to be within the preset range, and when the vehicle travels on the set route again, the optimal power generation power is generated. And generating power according to each planned optimal generation power. The method can eliminate the hysteresis of power generation in the process of adjusting the power generation power of the generator.

    本发明涉及一种燃料电池汽车能量管理方法及系统,属于电池能量管理技术领域;预先记录车辆行驶在既定路线时的工况数据和车辆平均功率,当车辆再次行驶在相同路线前,根据此时的动力电池SOC预先分段规划出最优发电功率以控制电池SOC在预设范围内,当车辆再次行驶在既定路线时,根据所规划的各最优发电功率发电。本方法能够在调节发电机发电功率过程中消除发电的滞后性。
