At the same time, during the hydrogen refueling process, the control module can also dynamically adjust the filling pressure of the hydrogen refueling gun according to changes in the hydrogen supply pressure and flow to ensure the stability and reliability of the filling. Finally, the second electronically controlled valve and the safety interlock device are also connected to the control module. When dangerous situations such as hydrogen leakage, abnormal pressure, and excessive temperature are detected, the control module can immediately cut off the hydrogen supply to the hydrogen refueling gun.
