Background
The fuel cell automobile taking hydrogen as energy has the advantages of environmental protection, high efficiency, zero pollution, zero emission and the like. Hydrogen fuel cell vehicles require hydrogen as fuel, and in order to reduce the volume ratio of hydrogen in vehicles, hydrogen needs to be stored in a high-pressure vehicle-mounted hydrogen storage bottle.
At present, the domestic common storage pressure reaches 35MPa, even higher pressure reaches 70 MPa. In order to supply such high-pressure hydrogen gas to the vehicle, a high-pressure hydrogen station is constructed to fill the high-pressure hydrogen gas in the station into the hydrogen cylinders on the vehicle through the hydrogen station. For a 35MPa vehicle-mounted hydrogen storage bottle, the corresponding hydrogen station is a 35MPa hydrogen station, and the storage pressure of a hydrogen storage tank for the station commonly adopted in China at present reaches 45 MPa. For a 70MPa vehicle-mounted hydrogen storage bottle, the corresponding hydrogen station is a 70MPa hydrogen station, and the storage pressure of a commonly adopted station hydrogen storage tank reaches 90 MPa. During hydrogenation, hydrogen is filled into the hydrogen fuel cell vehicle through the hydrogen storage tank for the station and the relevant connecting pipe valve.
In the existing hydrogen filling station, each pressure-level station hydrogen storage tank is respectively connected with an independent compressor, so that hydrogen from a hydrogen source is supplied to one pressure-level station hydrogen storage tank through one compressor, and then supplied to another pressure-level station hydrogen storage tank through another compressor, so that each pressure-level station hydrogen storage tank can be effectively filled.

Due to the structure, hydrogen coming out of the hydrogen source can be sent to different hydrogen storage tanks for stations through one compressor to be stored, so that the investment of the compressor is saved, and the cost is saved.

The process realizes that the second station hydrogen storage tank is filled by using the hydrogen in the first station hydrogen storage tank as the hydrogen source when the pressure of the hydrogen source is lower.
