[0002] In the fuel cell system hydrogen filling process, it is particularly important to control the internal pressure of the fuel cell hydrogen storage system. The optimal pressure point can ensure the safety and normal service life of the fuel cell hydrogen storage system; currently on the market for fuel cell systems There are few electronic control means involved in the filling pressure control. The current hydrogen filling scheme used in the fuel cell system is to supply hydrogen manually by personnel. The operator refers to the pressure value displayed on the mechanical pressure gauge connected in series on the pipeline of the hydrogen storage system. Then artificially calculate the amount of hydrogen filling; this will not only cause the pressure of the hydrogen storage system to be uneven, but also under the long-term running state, the overcharge state will affect the service life of the hydrogen storage bottle;

[0003] In addition, hydrogen is easy to leak, the diffusion speed of hydrogen is 3.8 times that of natural gas, and hydrogen can burn when the volume concentration of air is very low; the fuel system of fuel cell electric vehicles should be equipped with high-voltage protection devices, when the internal pressure of hydrogen cylinders When the pressure is higher than the required pressure, the protective device should be able to cut off the fuel input in time, but when a failure or accident occurs, the fuel system needs to be ventilated, and the direction and direction of the gas flow should be far away from people, electricity, and ignition sources; but The hydrogen filling of the existing fuel cell system basically adopts manual on-site filling, and the escaping hydrogen will cause harm to personnel. In addition, the electrical terminals, electronic switching devices or ignition sources of the car are very likely to generate static sparks to detonate the hydrogen and cause serious damage. loss of personnel and property
