Abstract

The invention proposes a compressed hydrogen storage and charging system of a hydrogen refueling station. A compressor is respectively connected with a high-pressure gas storage cylinder, a medium-pressure gas storage cylinder, a low-pressure gas storage cylinder and a direct charging pipeline by control valve pipelines; the high-pressure gas storage cylinder, the medium-pressure gas storage cylinder and the low-pressure gas storage cylinder are respectively connected with a high-pressure gas charging pipeline, a medium-pressure gas charging pipeline and a low-pressure gas charging pipeline by pipelines, and are all connected with a release pipeline by pipelines; a gas inlet side pipeline of the release pipeline is connected with a control valve; pipelines on gas intake sides of the high-pressure gas storage cylinder, the medium-pressure gas storage cylinder and the low-pressure gas storage cylinder are all connected with pressure sensors; and a data controller is in signal connection with the pressure sensors and the compressor. The system has the following beneficial effects: the system not only can charge vehicle-mounted gas storage cylinders of hydrogen fuel vehicles through the gas storage cylinder set, but also can directly charge the vehicle-mounted gas storage cylinders of the hydrogen fuel vehicles so as to realize intelligent control of compressed hydrogen storage and charging of the hydrogen refueling station.

Description

technical field [0001] The invention relates to the technical field of hydrogen gas storage in a hydrogen refueling station, in particular to a hydrogen compression gas storage and gas charging system in a hydrogen refueling station. Background technique [0002] The hydrogen fuel cell working process of hydrogen fuel vehicles can achieve zero emissions, and there is no hydrogen leakage problem. Compared with electric vehicle lithium batteries, the performance is more stable and safe. The technology of the vehicle-mounted hydrogen high-pressure gas storage tank is also mature and has high safety. The hydrogen refueling time of hydrogen fuel vehicles is equivalent to that of gasoline and diesel vehicles, and the cruising range of hydrogen fuel vehicles can reach more than 500 kilometers, which is about twice that of electric vehicles. The hydrogen refueling of hydrogen fuel vehicles needs to be carried out in hydrogen refueling stations, and the country needs to gradually es...
