The invention discloses an energy management method, device and system for a fuel cell hybrid electric vehicle and a storage medium. The energy management method comprises the steps that S1, the power which should be supplied by an energy system and the required power of the whole vehicle are obtained; s2, according to the power to be supplied by the energy system and the power required by the whole vehicle, separating a fluctuating power signal of the FCHEV in the driving process through an adaptive sliding mean filter to obtain a high-frequency power signal and a low-frequency power signal; and S3, secondary power distribution based on reinforcement learning is carried out on the low-frequency power signals. By the adoption of the technical scheme, under the combined driving working condition, the fuel economy is improved, and the FCS degradation rate is reduced.

    本发明公开一种燃料电池混合电车能量管理方法和装置、系统、存储介质,包括:步骤S1、获取能源系统所应供给的功率和整车需求功率;步骤S2、根据能源系统所应供给的功率和整车需求功率,通过自适应滑动均值滤波器分离FCHEV在行驶过程中波动的功率信号,得到高频功率信号和低频功率信号;步骤S3、对低频功率信号进行基于强化学习的二次功率分配。采用本发明的技术方案,在组合行驶工况下,提高了燃油经济性,降低了FCS退化率。
