The invention discloses a fuel cell system control method and device and a fuel cell passenger car, and belongs to the technical field of fuel cell passenger car control. When the fuel cell system needs to be stopped actively or passively, the whole vehicle controller determines to send a stop command or an emergency stop command to the fuel cell system by judging the real-time state of the whole vehicle, and controls high-low voltage power supply of the whole vehicle according to the real-time state to meet the stop or emergency stop requirement of the fuel cell system. And the whole vehicle stop or sudden stop instruction is ensured to be consistent with the actual execution process of the fuel cell system. The fuel cell system can be matched with a correct shutdown process according to the state of the whole vehicle, and shutdown errors of the fuel cell system are reduced. The problem that the risk of shutdown errors exists in shutdown of the fuel cell system in the prior art is solved.
本发明公开了一种燃料电池系统控制方法、装置及燃料电池客车,属于燃料电池客车控制技术领域。当燃料电池系统需要主动或被动停机时,整车控制器通过判断整车实时状态来确定向燃料电池系统发送停机或急停命令,并根据实时状态控制整车高低压供电满足燃料电池系统停机或急停需求,保证整车停机或急停指令与燃料电池系统实际执行过程保持一致。能够使燃料电池系统根据整车状态匹配正确的停机流程,降低燃料电池系统停机错误的发生。解决了现有技术中存在“燃料电池系统停机存在停机错误的风险”的问题。
