The invention belongs to the technical field of energy management and control, and provides an energy management and control method and system for a passenger car fuel cell system, when the power of a fuel cell is not less than the required power of the whole car, the power of the fuel cell only needs to meet the maximum value not less than the required power of the whole car, and the electric energy of the fuel cell is firstly supplied to the required power of the whole car; redundant electric energy is transmitted to the power battery; when the power of the fuel cell is smaller than the required power of the whole vehicle, the power of the fuel cell only needs to be smaller than the minimum value of the required power of the whole vehicle, all electric energy of the fuel cell is used up, and other energy is provided by the power cell. The influence of different working conditions and environments on the power of the fuel cell and the required power of the whole vehicle is considered, and the power of the whole vehicle does not only take a motor as an example, but also takes energy distribution into consideration, so that the energy distribution is more reasonable, the size and the weight of the power cell are further reduced, and the power of power accessories is considered. And the stability of the SOC of the power battery is maintained through joint participation of multiple factors.
本发明属于能量管理控技术领域,提供了一种客车燃料电池系统能量管理控制方法及系统,当燃料电池功率不小于整车需求功率时,燃料电池功率只需要满足不小于整车需求功率的最大值,燃料电池的电能首先供应整车需求功率,多余的电能输送到动力电池;当燃料电池功率小于整车需求功率时,燃料电池功率只需要满足小于整车需求功率的最小值,燃料电池的电能全部使用完毕,其他能量由动力电池提供。考虑到了工况、环境的不同,对于燃料电池功率以及整车需求功率的影响,并且整车功率不再单单以电机为例,而是同时将能量分配考虑进去,使能量分配更加合理,进一步减小动力电池尺寸和重量,对电源附件功率的考虑,通过多因素共同参与维持动力电池SOC稳定。
