The invention provides a hydrogen storage pressure diagnosis method and device for a hydrogen fuel cell vehicle, electronic equipment and a medium, and the method comprises the steps: obtaining a first pressure value on a vehicle sensor and a second pressure value on a hydrogen adding machine sensor after the hydrogen adding of the hydrogen fuel cell vehicle is completed through a hydrogen adding machine; a pressure abnormal state is obtained based on the difference value of the first pressure value and the second pressure value, if the pressure abnormal state is abnormal, the pressure abnormal state and the hydrogen adding machine number are newly added to a historical abnormal record, the historical abnormal record is read, a vehicle sensor fault state is obtained based on the historical abnormal record, and if the vehicle sensor fault state is a fault, the vehicle sensor fault state is determined. By means of the pressure diagnosis method, whether the vehicle pressure sensor deviates or is not accurate or not can be diagnosed, meanwhile, the vehicle pressure sensor can be corrected, and therefore hydrogen storage safety of the hydrogen fuel cell vehicle is guaranteed.

    本发明提供一种氢燃料电池车储氢压力诊断方法、装置、电子设备及介质,该方法包括通过加氢机对氢燃料电池车加氢完成后,获取车辆传感器上的第一压力值和加氢机传感器上的第二压力值,基于第一压力值和第二压力值的差值得到压力异常状态,若压力异常状态为异常,将本次压力异常状态和加氢机编号新增至历史异常记录,读取历史异常记录,基于历史异常记录得到车辆传感器故障状态,若车辆传感器故障状态为故障,则根据第二压力值对车辆传感器进行校正,通过本压力诊断方法可以诊断车辆压力传感器是否出现偏差或不准的情况,同时还可以对车辆压力传感器进行校正,从而保证氢燃料电池车储氢安全。
