The invention discloses a multi-fuel cell system energy control method and control system and a vehicle. The method comprises the steps that request power of a fuel cell system is obtained; when the request power is smaller than or equal to the longest service life output power of the fuel cell systems, the multiple fuel cell systems are controlled to alternately output power; and when the request power is greater than the longest life output power of the fuel cell systems, controlling the plurality of fuel cell systems to respectively output corresponding power. According to the energy control method for the multi-fuel cell system, energy management of the multi-fuel cell system can be finely controlled according to the magnitude relation between the longest-life output power and the request power of the fuel cell system, the overall service life of the fuel cell system is prolonged, and the economical efficiency of a fuel cell vehicle is improved.
本发明公开了一种多燃料电池系统能量控制方法及控制系统、车辆,所述方法包括:获取燃料电池系统的请求功率;在请求功率小于等于燃料电池系统的最长寿命输出功率时,控制多个燃料电池系统交替输出功率;在请求功率大于燃料电池系统的最长寿命输出功率时,控制多个燃料电池系统分别输出相应的功率。本发明的多燃料电池系统能量控制方法,能够根据燃料电池系统的最长寿命输出功率与请求功率的大小关系,对多燃料电池系统的能量管理进行精细化控制,提高燃料电池系统的整体使用寿命,提升燃料电池车辆的经济性。
