The embodiment of the invention relates to the technical field of hydrogen fuel cells, and particularly discloses a hydrogen fuel cell control method and system. According to the embodiment of the invention, vehicle state monitoring is carried out in real time to generate state monitoring data; according to the state monitoring data, when an A + signal and a CC2 signal exist and the SOC of the power battery is lower than 70%, continuous charging is allowed; according to the state monitoring data, when an A + signal and a CC2 signal exist and the SOC of the power battery is not lower than 70%, continuous charging is not allowed; and according to the state monitoring data, when the SOC of the power battery is not lower than 70% in the running process of the vehicle, charging is allowed. The power matching problem of the fuel cell and the power cell can be solved, the type selection requirement for increasing the power of the cell due to the fact that the power requirement of the vehicle is large is avoided, and the problem that the dynamic property of the vehicle is obviously changed due to the characteristics of the fuel cell and poor driving feeling is caused when the SOC is high is solved.

    本发明实施例涉及氢燃料电池技术领域,具体公开了一种氢燃料电池控制方法及系统。本发明实施例通过实时进行车辆状态监测,生成状态监测数据;根据状态监测数据,在有A+信号和CC2信号,且动力电池SOC低于70%时,允许继续充电;根据状态监测数据,在有A+信号和CC2信号,且动力电池SOC不低于70%时,不允许继续充电;根据状态监测数据,在车辆行驶过程中,且动力电池SOC不低于70%时,允许充电。能够解决燃料电池与动力电池的功率匹配问题,避免因为车辆功率需求大,增大电池功率的选型需求,且解决在高SOC时,车辆的动力性不会因为燃料电池特性导致明显的变化,造成不好的驾驶感受的问题。
