When the high-pressure gaseous hydrogen storage tank charges hydrogen into the low-pressure gaseous hydrogen storage tank, a pressure difference mode is generally utilized. After the valve of the high-pressure gaseous hydrogen storage tank is opened, hydrogen is naturally released into the low-pressure gaseous hydrogen storage tank through the gas transmission hose. Along with the release of the hydrogen, the pressure in the high-pressure gaseous hydrogen storage tank gradually decreases until the pressure in the low-pressure gaseous hydrogen storage tank reaches a certain value, and then the hydrogen filling is stopped.
The inventor(s) find that the traditional hydrogen charging mode has certain disadvantages: 1. when the pressure in the low-pressure gaseous hydrogen storage tank reaches a certain value, the hydrogen cannot be continuously charged, and whether the hydrogen in the low-pressure gaseous hydrogen storage tank is full cannot be detected. 2. The traditional hydrogen charging mode can not monitor the pressure in the low-pressure gaseous hydrogen storage tank in real time and can not adjust the hydrogen charging rate. If continuous hydrogen charging is carried out, the temperature in the low-pressure gaseous hydrogen storage tank is easily increased, the pressure in the hydrogen storage tank is further increased, and when the pressure is close to or exceeds the safety pressure of the hydrogen storage tank, the risks of hydrogen leakage, deformation, explosion and the like of the hydrogen storage tank are extremely easy to occur.
In order to solve the problems, the utility model provides a hydrogen charging device for a solid metal hydrogen storage tank.

The early warning module 401, the power supply module 402 and the time adjusting module 403 are integrally arranged on the controller 4, so that the integration level is high and the space occupation is small.
In another alternative embodiment, the early warning module 401 is electrically connected to the pressure detecting module 2, and when the pressure detecting module 2 detects that the gas transmission pressure of the high-pressure gaseous hydrogen storage tank or the gas inlet pressure of the metal hydrogen storage tank is abnormal, the pressure detecting module 2 sends a feedback signal to the early warning module 401, and the early warning module 401 sends an alarm prompt to an operator.
In another alternative embodiment, the power module 402 is electrically connected to the pre-alarm module 401 and cooperates with the same.
