Abstract

The invention provides a method and system for rapid filling of hydrogen energy in a hydrogen fueling station. The method and system overcome the problems of long waiting time for hydrogen fueling andlow hydrogen fueling efficiency of fuel-cell vehicles in the prior art. The method comprises the following steps: S1, acquiring the pressure threshold data of preset buffer bottles, and filling the preset buffer bottles with hydrogen with corresponding pressure according to the pressure threshold; S2, receiving a hydrogen fueling signal, and filling the hydrogen storage bottle of a current vehicle with hydrogen via the preset buffer bottles; S3, acquiring the interior pressure data information of the hydrogen storage bottle of the current vehicle, and comparing the pressure data with the hydrogen pressure of a current buffer bottle to determine whether a pressure difference is less than the preset pressure threshold; and S4, if so, disconnecting the hydrogen storage bottle with the current buffer bottle, or if not, continuing the connection between the hydrogen storage bottle and the preset buffer bottles and filling the hydrogen storage bottle with hydrogen until the hydrogen storageamount of the hydrogen storage bottle reaches a preset volume threshold. With the method and system of the invention, superimposed hydrogen fueling via the buffer bottles with different pressures isemployed for the vehicle, so the hydrogen fueling efficiency of the fuel-cell vehicle is improved, and a plurality of vehicles can be filled with hydrogen simultaneously.

Description

technical field [0001] The invention relates to the field of new energy applications, in particular to a method and system for quickly filling hydrogen energy in a hydrogen refueling station. Background technique [0002] With the development of economy and technology, the excessive development and use of traditional industrial energy, carbon dioxide emissions are increasing, causing global warming, and now countries all over the world are working hard to reduce carbon emissions. [0003] A fuel cell vehicle is a type of electric vehicle. The energy of its battery is directly converted into electricity through the chemical action of hydrogen and oxygen rather than through combustion. The chemical reaction process of fuel cells will not produce harmful products, so fuel cell vehicles are pollution-free vehicles, and the energy conversion efficiency of fuel cells is 2 to 3 times higher than that of internal combustion engines. Therefore, in terms of energy utilization and envi...
