Abstract

The invention provides a hydrogen energy supply method and system for a hydrogen refueling station, which is used to solve the problem of low hydrogen energy supply efficiency in the hydrogen refueling station. The method includes: S10: Obtain the pressure in the hydrogen energy supply equipment and the pressures in multiple sets of buffer bottles; S20: compare the pressure in the hydrogen energy supply equipment with the pressures in the multiple sets of buffer bottles to obtain multiple group pressure difference; S30: judge whether any of the multiple groups of pressure differences is lower than the preset pressure difference ratio, if so, adjust the control logic of the compression equipment to compress and charge the hydrogen energy in the hydrogen energy supply equipment Fill into corresponding buffer bottles for storage. By adopting the present invention, by arranging multiple sets of buffer bottles with different pressure differences, the recovery residual pressure of the hydrogen energy supply equipment can be effectively reduced, and the supply efficiency and transportation efficiency can be improved.

Description

technical field [0001] The invention relates to the application field of hydrogen energy, in particular to a hydrogen energy supply method and system for a hydrogen refueling station. Background technique [0002] When hydrogen refueling stations provide hydrogen refilling for hydrogen energy vehicles and other equipment, due to the high cost of on-site hydrogen production and certain safety risks, most hydrogen refueling stations basically use tube bundle vehicles to transport and provide hydrogen sources, and then the tube bundles The hydrogen energy in the vehicle is compressed by the compressor and filled into the buffer bottle of the hydrogen refueling station to refuel the vehicle. The working pressure of the hydrogen storage bottle of the existing hydrogen energy car is 70MPa, and the working pressure of the hydrogen storage bottle of the bus or truck is 35MPa, and the compressor has a compression ratio limitation. For example, a compressor with a compression ratio of...
