Embodiment 1

[0040] like figure 1 As shown, this embodiment provides a hydrogen supply method applied to a hydrogen refueling station, including steps:

[0041] S10: Obtain the gas pressure value in each group of hydrogen buffer bottles in the hydrogen refueling station, and judge whether the gas pressure value of each group of hydrogen buffer bottles is lower than the preset pressure value, and if so, go to step S20;

[0042] S20: Obtain the number of hydrogen buffer bottle groups whose gas pressure value is lower than the preset pressure value. If the number is two or more, proceed to step S30. If the number is one group, supply the first hydrogen gas to the equipment through the compressor The hydrogen compressed and filled into the hydrogen buffer bottle set;

[0043] S30: Obtain the filling priority of the two or more hydrogen buffer bottle sets, compress the hydrogen in the hydrogen supply equipment through the compressor, and fill it into the hydrogen buffer bottle set with higher ...

Embodiment 2

[0052] like figure 2 As shown, this embodiment also provides a hydrogen supply method applied to a hydrogen refueling station, which is different from the first embodiment in that it further includes steps S01, S02, S31, S40, and S41.

[0053] Step S01, divide the hydrogen buffer bottles in the hydrogen refueling station into multiple groups, and set a corresponding filling priority for each group of buffer bottles.

[0054] Step S02 , according to the high and low order of the filling priority, perform hydrogen refueling on the hydrogen refueling vehicles in order from low to high.

[0055] On the one hand, the filling priority is used as the basis for replenishing hydrogen in the hydrogen buffer bottle, and the hydrogen is replenished from high to low; on the other hand, when fuel cell vehicles are refueled, the filling priority is also used as the priority of the hydrogenation sequence, that is, When refueling a fuel cell vehicle, first refuel the fuel cell vehicle from t...

Embodiment 3

[0064] like image 3 As shown, this embodiment provides a hydrogen supply system applied to a hydrogen refueling station, including:

[0065] Pressure detection module 31: used to obtain the gas pressure value in each group of hydrogen buffer bottles in the hydrogen refueling station, and judge whether the gas pressure value of each group of hydrogen buffer bottles is lower than the preset pressure value, and if so, go to the quantity detection module;

[0066] Quantity detection module 32: used to obtain the quantity of hydrogen buffer bottle groups whose gas pressure value is lower than the preset pressure value, if the quantity is two or more, then enter the priority judgment module, if the quantity is one, then pass the compressor Compressing and filling the hydrogen in the first hydrogen supply equipment into the hydrogen buffer bottle set;

[0067] Priority judging module 33: used to obtain the filling priority of the two or more hydrogen buffer bottle groups, compress ...

Abstract

The invention provides a hydrogen supply method and system applied to a hydrogen refueling station. The method comprises the following steps: S10, acquiring gas pressure values in hydrogen buffer cylinders in the hydrogen refueling station and judging whether the gas pressure values in hydrogen buffer cylinders are lower than a preset pressure value or not, if so, entering a step S20; S20, acquiring the quantity of the hydrogen buffer cylinder groups, the gas pressure values of which are lower than the preset pressure value, if the quantity is greater than two, entering the step S30, if the quantity is one, compressing and filling hydrogen in first hydrogen supply equipment to the hydrogen buffer cylinder groups; and S30, acquiring filling priority of the more than two hydrogen buffer cylinder groups, compressing hydrogen in the hydrogen supply equipment through a compressor, and filling the hydrogen to the hydrogen buffer cylinder groups, the priority of which is relatively high. By supplementing gas to the hydrogen buffer cylinders, the hydrogen refueling efficiency of the hydrogen refueling station can be improved, and the gas supplementing efficiency of the hydrogen buffer cylinders can be also improved.

Description

technical field [0001] The invention relates to the field of hydrogen refueling stations, in particular to a method and system for supplying hydrogen applied to hydrogen refueling stations. Background technique [0002] As a clean and non-polluting vehicle, hydrogen fuel cell vehicles are of great help in environmental protection, but the current domestic battery vehicles are not widely popularized and the scope is small. More importantly, the construction of hydrogen refueling stations is slow , the number is small, and it is difficult for battery vehicles to find hydrogen refueling stations for refueling. Hydrogen refueling stations also need hydrogen supply when they provide fuel for battery vehicles. Some of the existing domestic hydrogen refueling stations use on-site hydrogen production technology, and some use tube-bundle vehicles to transport hydrogen and supply it to hydrogen refueling stations. A compressor and multiple sets of hydrogen buffer bottle sets are requ...
