Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production, filling and replacement, and particularly relates to a hydrogen production, filling and replacement method, system and storage medium based on a hydrogen production, filling and replacement system. Background Art

[0002] With the continuous progress of technology, the production cost of hydrogen energy has gradually decreased, and the application fields have become increasingly wide. The market of hydrogen energy terminal devices such as hydrogen energy vehicles has increased significantly, and the demand of users for hydrogen refueling stations has become increasingly prominent. When the hydrogen energy in the hydrogen storage device built in a hydrogen energy bicycle is exhausted, the user needs to quickly find a hydrogen refueling station to replace the hydrogen storage device. The existing technology is to use multiple hydrogen production devices to fill hydrogen into multiple hydrogen storage devices through pipelines. In this process, the opening and closing angles of the master and slave valves are set to control the transmission of hydrogen to the corresponding multiple hydrogen storage devices. In addition, the existing cabinet door opening method is that the user freely selects the opened cabinet door or the system randomly opens it.

[0003] However, this hydrogen production, filling and replacement method will cause multiple hydrogen production machines to be in a high-intensity working state for a long time, which will seriously shorten the service life of the hydrogen production machines. In the case of a high hydrogen replacement frequency of users, the hydrogen production, filling and replacement efficiency of the existing hydrogen production, filling and replacement method is low and cannot meet the actual needs of users.

[0028] In the subsequent description, the suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of describing the present invention, and they have no specific meaning in themselves. Therefore, "module" and "component" can be used interchangeably.

[0029] The present invention discloses a hydrogen production, filling, and replacement method based on a hydrogen production, filling, and replacement system. The hydrogen production, filling, and replacement system includes hydrogen filling cabinets arranged in M rows and N columns. For example, Figure 1 as shown in the hydrogen production, filling, and replacement system in [reference], it includes 16 cabinet doors, and the cabinet doors are controlled by a control system to open or close. The cabinet doors are divided into four rows, with four in each row, as shown in the attached Figure 1 drawing (where: Z1 - Z4: the first hydrogen production machine to the fourth hydrogen production machine; F1 - F4: the first row to the fourth row of the hydrogen production, filling, and replacement system; G1 - G16: the first cabinet door to the sixteenth cabinet door). From top to bottom, the first row is F1, the second row is F2, the third row is F3, and the fourth row is F4. The cabinet doors in the F1 row are G1, G2, G3, and G4 respectively. The cabinet doors in the F2 row are G5, G6, G7, and G8 respectively, and so on. Each row of four cabinet doors is provided with an accommodation space, which contains exchangeable hydrogen storage bottles and a hydrogen filling device, and the hydrogen storage bottles are connected to the hydrogen filling device. Each row of hydrogen filling cabinets is connected to a hydrogen production machine. After the hydrogen production machine produces hydrogen, it is transported to the hydrogen filling device in the hydrogen filling cabinet, and then the hydrogen filling device fills the hydrogen into the hydrogen storage bottles.

[0030] It should be noted that the hydrogen production machine can be provided with multiple hydrogen outlets, and each hydrogen outlet is respectively connected to an independent hydrogen filling device. In addition, the hydrogen production machine can also be provided with only one hydrogen outlet, and the independent hydrogen supply to each hydrogen filling device is realized by setting branch pipes and valves on the air pipe connecting the hydrogen outlet and the hydrogen filling device.

[0031] Further, each accommodation space includes a hydrogen filling device. The hydrogen storage bottle is connected to the hydrogen filling device, and each hydrogen filling device is connected to the hydrogen generator responsible for that row. For example, the hydrogen generator Z1 supplies hydrogen to the hydrogen filling devices in the four cabinet doors (G1 to G4) of row F1, and so on. After the hydrogen generator produces hydrogen, it is transported to the hydrogen filling device in the hydrogen filling cabinet where the hydrogen storage bottle to be filled is located, and then the hydrogen filling device fills the hydrogen storage bottle with hydrogen.

[0032] Further, each hydrogen storage bottle is provided with a readable and writable electronic chip. The electronic chip records the identity information and hydrogen storage information of the hydrogen storage bottle. The identity information includes but is not limited to the number, factory time, model, hydrogen storage capacity, service life, and preset hydrogen charging and discharging times. The hydrogen storage information includes the current hydrogen capacity and the cumulative number of hydrogen charging and discharging times. It should be noted that the current hydrogen capacity of the hydrogen storage bottle here can be detected and obtained by a hydrogen capacity detection unit arranged in the hydrogen storage bottle.

[0033] Correspondingly, the hydrogen filling device is provided with a data reading and writing unit, and this data reading and writing unit can read and write the electronic chip of the hydrogen storage bottle.

[0034] When the user opens the cabinet door to take away the full hydrogen storage bottle and puts in the hydrogen storage bottle to be filled, since the data reading and writing unit cannot read the electronic information of the electronic chip on the full hydrogen storage bottle, it will send a notification message to the control system of the hydrogen replacement cabinet, and the control system regards that the user has taken out the full bottle in this cabinet.

[0035] When the user deposits the hydrogen storage bottle to be filled into the cabinet and completes the connection with the hydrogen filling device in the cabinet, the installation position of the data reading and writing unit on the hydrogen filling device exactly corresponds to the position of the electronic chip on the placed hydrogen storage bottle, so that the data reading and writing unit can smoothly read and write the electronic chip. If the number read by the data reading and writing unit on the hydrogen storage bottle to be filled is different from the factory number in the identity information of the full hydrogen storage bottle just taken away, it will send a notification message to the control system of the hydrogen production, filling and replacement system, and the control system regards that the user has put the hydrogen storage bottle to be filled into the cabinet.

[0036] Before formal hydrogen filling, when the hydrogen storage bottle is connected to the hydrogen filling device, the data reading and writing unit of the hydrogen filling device will read the identity information and hydrogen storage information in the electronic chip of the hydrogen storage bottle, calculate the current life of the hydrogen storage bottle according to the factory time, and compare it with the service life. When it exceeds the service life, it will refuse to fill hydrogen for this hydrogen storage bottle and no longer perform the subsequent hydrogen filling steps, waiting for the user to come and take away the hydrogen storage bottle to be filled. The data reading and writing unit will also read the cumulative number of hydrogen charging and discharging times and compare it with the preset hydrogen charging and discharging times. When it exceeds the preset hydrogen charging and discharging times, it will also refuse to fill hydrogen for this hydrogen storage bottle and no longer perform the subsequent hydrogen filling steps, waiting for the user to come and take away the hydrogen storage bottle to be filled.

[0037] Further, before starting hydrogen filling, it is also necessary to determine whether the user has returned the hydrogen storage bottle. Specifically, it can be judged whether the hydrogen storage bottle has been returned by whether the number of the hydrogen storage bottle has changed. In addition, it is also necessary to determine whether the returned hydrogen storage bottle is the hydrogen storage bottle to be filled with hydrogen. Specifically, the current hydrogen capacity of the hydrogen storage bottle can be obtained. If the current hydrogen capacity is less than a preset percentage of the full bottle capacity, for example, 90% of the full bottle, the hydrogen storage bottle is considered to be the hydrogen storage bottle to be filled with hydrogen. In addition, when it is determined that the user has returned the hydrogen storage bottle, and the hydrogen storage bottle belongs to the hydrogen storage bottle to be filled with hydrogen, and the service life and the cumulative number of charge and discharge times of the hydrogen storage bottle both meet the standards, the data reading and writing unit will read the current hydrogen content and hydrogen storage capacity to calculate the hydrogen filling amount for this time.

[0038] After the hydrogen filling is completed, the data reading and writing unit will write the actual hydrogen filling amount, the increment of the hydrogen filling times by one, and the data of the actual hydrogen filling amount for this time into the electronic chip of the hydrogen storage bottle to update the current hydrogen content, the cumulative number of hydrogen charge and discharge times, and the current hydrogen capacity corresponding to the hydrogen storage bottle.

[0039] Further preferably, the hydrogen energy vehicle using the hydrogen storage bottle is also equipped with a detection device for detecting the current hydrogen content of the hydrogen storage bottle and a data reading and writing unit. The detection device can detect the hydrogen content in the hydrogen storage bottle after the user has consumed it during riding and write it into the electronic chip through the data reading and writing unit.

[0040] The hydrogen production, filling and replacement method includes: when the hydrogen production, filling and replacement system receives the user's hydrogen replacement request, it detects the capacities of the hydrogen storage bottles in all hydrogen filling cabinets, obtains the row with the largest number of full-capacity hydrogen storage bottles in M rows, and randomly opens the cabinet door of a hydrogen filling cabinet storing full-capacity hydrogen storage bottles in this row for the user to exchange the hydrogen storage bottle. After the hydrogen filling device detects the hydrogen storage bottle to be filled with hydrogen put in by the user, it fills hydrogen for the hydrogen storage bottle to be filled with hydrogen.

[0041] Specifically, refer to the appendix Figure 1 , the default initial state of the hydrogen storage bottles in 16 cabinets is the full-bottle state. In this case, if the hydrogen replacement request of the first user is received, any one of the 16 cabinet doors will be randomly popped open. As shown in the appendix Figure 2 , black symbolizes the full bottle, and white symbolizes the hydrogen storage bottle to be filled with hydrogen. The control system selects to pop open the G1 cabinet door located in the F1 row. After the user takes away the full bottle and puts in the hydrogen storage bottle to be filled with hydrogen and manually closes the cabinet door, when the control system detects the hydrogen storage bottle to be filled with hydrogen through the hydrogen filling device and the cabinet door is closed, the hydrogen filling process will start: the hydrogen production machine Z1 transmits hydrogen to the hydrogen filling device in G1, and then the hydrogen filling device fills hydrogen for the hydrogen storage bottle to be filled with hydrogen.

[0042] At this time, G1 is in the hydrogen charging state, and there are only 3 cabinet doors (G2, G3, G4) in row F1 storing full bottles, while the number of full bottles in the other three rows F2, F3, and F4 is 4. In this case, different from randomly popping open a cabinet door for the user to replace hydrogen, when there is another user's hydrogen replacement request within a short period of time, any cabinet door can be popped open from the row with the largest number of full bottles, enabling the user to obtain the full bottle inside to complete hydrogen replacement, that is, randomly select one row from F2, F3, or F4, and then randomly select one cabinet door from the selected row. As Figure 3 shown, the control system selects G5 in row F2 as the popped open cabinet door.

[0043] After the user takes away the full hydrogen storage bottle in G5 and puts in the hydrogen storage bottle to be charged, and manually closes the cabinet door, when the control system detects the hydrogen storage bottle to be charged and the cabinet door is closed, it starts the hydrogen charging process: The hydrogen generator Z2 transmits hydrogen to the hydrogen charging device in G5, and then the hydrogen charging device charges the hydrogen storage bottle to be charged in the cabinet.

[0044] At this time, G5 is in the state of waiting to be charged. Usually, a small-power hydrogen generator Z1 takes a certain amount of time (such as four hours) to fill the hydrogen storage bottle in G1. In this case, there are only 3 cabinet doors in rows F1 and F2 storing full bottles, while the number of full bottles in rows F3 and F4 is 4. Then, after receiving the user's hydrogen replacement request next time, any cabinet door in row F3 or F4 will be popped open preferentially.

[0045] It should be noted that the control system will update the number of full bottles in each row in real time, and will automatically add one to the corresponding number of full bottles in the row where the hydrogen storage bottle to be charged is filled.

[0046] As a preferred embodiment, since the exchange order in this embodiment is that the user first takes out the full hydrogen storage bottle from the exchange cabinet and then puts in the hydrogen storage bottle to be charged, it is possible that after the user takes out the full hydrogen storage bottle from the exchange cabinet, the user does not put the hydrogen storage bottle to be charged into the exchange cabinet. That is to say, at this time, the user holds two hydrogen storage bottles, and there is no hydrogen storage bottle in the exchange cabinet. Based on this, if the user has an uncompleted order history in the system and the order shows that there is an unreturned hydrogen storage bottle to be charged. Then, after the user initiates this hydrogen replacement request, the system will remind the user to first return the unreturned hydrogen storage bottle shown in the previous order history. After the control system recognizes through the hydrogen charging device that the hydrogen storage bottle to be charged has been put in (it should be noted that the hydrogen charging cabinet for returning the hydrogen storage bottle to be charged is different from the hydrogen charging cabinet where the full hydrogen storage bottle will be popped open later. The hydrogen charging cabinet for returning the hydrogen storage bottle to be charged can be an exchange cabinet without a stored hydrogen storage bottle), then it opens the full bottle cabinet door; if the control system does not detect the hydrogen bottle, it will remind the user to return it again.

[0047] Preferably, if there are more than two hydrogen storage bottles to be hydrogenated in the same row, that is, when the number of people using the hydrogen exchange cabinet to exchange hydrogen is particularly large, resulting in a particularly high hydrogen exchange frequency, it is very likely that there are multiple hydrogen storage bottles to be hydrogenated in the same row. In this case, the time when the more than two hydrogen storage bottles to be hydrogenated enter the cabinet is obtained, and the hydrogen generator delivers hydrogen to the hydrogen filling device in the hydrogen filling cabinet where the more than two hydrogen storage bottles to be hydrogenated are located according to the order of the entering time, so as to hydrogenate the hydrogen storage bottles.

[0048] Specifically, for example, the hydrogen storage bottle in row F1 in cabinet G1 that is waiting to be hydrogenated is being hydrogenated, the hydrogen storage bottles in cabinets G2 and G3 that are waiting to be hydrogenated, and G4 is full. In this case, the control system can generate a hydrogen filling work order for row F1 arranged according to the previous hydrogen exchange order of users. For example, the time when the first user took the hydrogen storage device in G1 was 2 pm, the time when the second user took the hydrogen storage device in G3 was 2:10 pm, and the time when the third user took the hydrogen storage device in G2 was 2:20 pm. Then the hydrogen filling order recorded in the generated hydrogen filling work order is G1-G3-G2, and this work order is updated in real time. For example, after the hydrogen storage bottle waiting to be hydrogenated in cabinet G1 is full, the hydrogen filling work order is updated to G3-G2.

[0049] Further, in another embodiment of the present application, the hydrogen filling order can also be adjusted secondly according to the current hydrogen content of multiple hydrogen storage bottles to be hydrogenated. For example, G1 is in the hydrogenation state, and G2, G3, and G4 are all in the state of waiting to be hydrogenated. Assuming that the hydrogen filling order is set according to the storage time of the aforementioned hydrogen storage bottles, the work order is G1-G2-G3-G4. If the current hydrogen content of G2 waiting to be hydrogenated is 15%, the current hydrogen content of G3 is 40%, and the current hydrogen content of G4 is 28% at this time, in this case, G3 only needs to be filled with another 55% to be full, while both G2 and G4 need to be filled with more hydrogen, which also requires more time to be full. Therefore, the hydrogen filling work order can be adjusted secondly to G1-G3-G4-G2. That is, after G1 is filled, G3 is filled first, which can produce a hydrogen storage bottle with a full capacity in row F1 in the shortest time for users to exchange.

[0050] Furthermore, considering that it takes four hours to fill a hydrogen storage bottle to be hydrogenated. If a hydrogen generator hydrogenates four hydrogen storage bottles to be hydrogenated at the same time (for example), after four hours of hydrogenation, the hydrogen content in the four hydrogen storage bottles to be hydrogenated is all one-fourth, and none of the bottles reaches the full state and none of them can be taken out by users for hydrogen exchange. The present invention sets that the hydrogen generator will only fill the next hydrogen storage bottle to be hydrogenated after filling one hydrogen storage bottle to be hydrogenated on the row it is responsible for. After four hours, at least one more full bottle can be produced for users to exchange hydrogen. And the same is true for other rows to hydrogenate in turn, so that (for example) four full bottles can be produced every four hours to meet the needs of users under medium and high hydrogen exchange intensities.

[0051] It should be noted that the hydrogen generator can be provided with multiple hydrogen outlets, and each hydrogen outlet is respectively connected to an independent hydrogen filling device. Additionally, the hydrogen generator can also be provided with only one hydrogen outlet, and the independent hydrogen supply to each hydrogen filling device is achieved by arranging branch gas pipes and valves on the gas pipe connecting the hydrogen outlet and the hydrogen filling device.

[0052] Preferably, the hydrogen generator is connected to the hydrogen filling devices in the same row through a first hydrogen transmission pipeline, and a first valve ( Figure 1 the small black dot above the hydrogen generator in the figure) is provided on the first hydrogen transmission pipeline. Whether the hydrogen generator supplies hydrogen to the hydrogen filling devices in the same row is controlled by controlling the opening or closing of the first valve.

[0053] An optional way to pop open the cabinet door: If the number of fully - filled hydrogen storage bottles in multiple rows is the same, the cabinet doors of the hydrogen filling cabinets in different rows are opened sequentially from top to bottom according to the row numbers. In the case of opening the cabinet doors of the hydrogen filling cabinets in different rows sequentially from top to bottom as described above, when the cabinet door of G1 in row F1 pops open, the next one to pop open is G5, then G9, and then G13. If Z1 and Z2 are set to assist each other, the time when Z2 can assist Z1 in hydrogen production is only within the time period between popping open G1 and G5. Because after the user takes out the fully - filled hydrogen storage bottle in G5 and puts in the hydrogen storage bottle to be filled, Z2 needs to pause assisting in hydrogen production for row F1 and instead fill the hydrogen storage bottle to be filled in G5 of row F2. Therefore, the actual time that Z2 can assist in hydrogen filling for row F1 is very limited. Based on this, in this embodiment, Z1 and Z3 can be set to assist each other, and the time when Z3 assists Z1 in hydrogen production is within the time period between popping open G1 and G9. In this way, Z3 can have a longer time to assist Z1 in hydrogen production. And further, after popping open G9, if Z1 is idle after filling the hydrogen storage bottles in cabinet G1, it can also assist Z3 in hydrogen supply in turn to fill the empty hydrogen storage bottles to be filled in G9.

[0054] Therefore, the hydrogen generator of the present invention is connected to the first hydrogen transmission pipeline in the spaced - apart row through a second hydrogen transmission pipeline, and a second valve is provided on the second hydrogen transmission pipeline. Whether the hydrogen generator and the hydrogen generator in the spaced - apart row supply hydrogen to the hydrogen filling devices in the spaced - apart row simultaneously is controlled by controlling the opening or closing of the second valve. That is to say, the hydrogen output by the hydrogen generator can have two directions. One direction is to transmit the hydrogen to the responsible row in the same row, and the other direction is to transmit the hydrogen to the spaced - apart row. For example, the control system can control the hydrogen generator Z1 to transmit the produced hydrogen to row F1, or it can also transmit the hydrogen to the spaced - apart row F3 when all four cabinets in row F1 are full of bottles. (Of course, the spaced - apart row of F1 can also be F4). Vice versa, the hydrogen generator Z3 can also transmit the produced hydrogen to row F1 to assist the hydrogen generator Z1 in hydrogen filling when all four bottles in row F3 are full.

[0055] In a valve control method, when supplying hydrogen to the same row, only the first valve is opened. When supplying hydrogen to non - same rows, only the second valve is opened.

[0056] In another valve control method, the first valve can be a multi - way valve, which can switch the hydrogen supply line of the hydrogen generator. The hydrogen generator can supply hydrogen only to the same row in the first switching state. When all the hydrogen storage devices in the same row are fully filled, it can be switched to the second switching state, and instead of supplying hydrogen to the same row, it supplies hydrogen to the spaced rows or adjacent rows. When supplying hydrogen to other rows, the second valves of the corresponding rows also need to be opened.

[0057] In another embodiment, the first valve can be bidirectional. When all the hydrogen storage devices on the spaced rows of this row are in a full state, the hydrogen generator on the spaced row can, conversely, assist in filling the empty - capacity hydrogen storage devices of this row. At this time, the first valve on this row can also be switched to the third switching state, that is, fully opened so that the hydrogen produced by the hydrogen generators in the same row and on the spaced rows can be transmitted over simultaneously to assist in filling the empty - capacity hydrogen storage devices of this row. At this time, the corresponding second valves between this row and the spaced rows also need to be opened.

[0058] A specific example: Usually, the hydrogen generator Z1 transmits hydrogen to the hydrogen storage device to be filled in the G1 cabinet of the F1 row. When all the hydrogen storage devices in the F3 row are in a full - bottle state, as Figure 1 shown, the control system controls the first valve body above Z1 to be fully opened, and the second valve between the F1 row and the F3 row is also opened. The hydrogen generator Z3 can transmit the hydrogen produced through the second hydrogen transmission pipeline between the F1 row and the F3 row to the F1 row. In this way, the hydrogen generators Z1 and Z3 can supply hydrogen to the G1 cabinet of the F1 row simultaneously, improving the hydrogen - filling efficiency.

[0059] In another embodiment, the hydrogen generator can not only assist the spaced rows but also assist the adjacent rows. For example, Z1 can assist the Z2 row, then Z1 can receive assistance from Z2, Z3, and Z4 at most simultaneously.

[0060] It should be noted that when all the hydrogen storage bottles in the same row of the hydrogen generator are full (at this time the hydrogen generator is in an idle state), the second valve can be opened to control the hydrogen generators in the same row and on the spaced rows to simultaneously supply hydrogen to the hydrogen - filling device on the spaced row.

[0061] In addition, except for the case where all the hydrogen storage bottles in the same row of the hydrogen generator are full, if the hydrogen storage bottles to be filled in the G1 cabinet of the F1 row no longer need to be filled due to limited charge - discharge times or service life, and all other cabinets in the F1 row are full, at this time the hydrogen generator Z1 is also in an idle state and can also assist the hydrogen generators of other rows in supplying hydrogen.

[0062] In some other embodiments of the present application, for details, please refer to the appendix Figure 4Schematic diagram of the hydrogen transmission pipeline structure shown, with four rows of hydrogen generators Z1, Z2, Z3, and Z4, capable of assisting in hydrogen filling for any row. M represents the first valve, which controls the hydrogen generator to transmit the produced hydrogen to the same row cabinet or assist in hydrogen filling for other rows; N represents the second valve, which is a multi-way valve that controls the flow direction of hydrogen in the second hydrogen transmission pipeline and is responsible for transmitting the hydrogen produced by Z1 to row F2 or row F3 or row F4. Among them: (1) Row F1 can assist adjacent row F2 in hydrogen filling: The hydrogen produced by Z1 first passes through M1. M1 switches its state and does not transmit to the same row but to other rows; when passing through N1, N1 switches its state and transmits to row F2 instead of other rows. At this time, M2 in row F2 is in a fully open state, that is, the hydrogen produced by Z2 and Z1 can be transmitted to row F2 simultaneously, and then the hydrogen filling device in the cabinet storing the hydrogen storage bottles to be filled hydrogen fills the hydrogen storage bottles; (2) Row F1 assists row F3 in hydrogen filling: The hydrogen produced by Z1 first passes through M1. M1 switches its state and does not transmit to the same row but to other rows; when passing through N1, N1 switches its state and does not transmit to row F2 but to other rows; when passing through N2, N2 switches its state and transmits to row F3 instead of other rows. At this time, M3 in row F3 is in a fully open state, that is, the hydrogen produced by Z3 and Z1 can be transmitted to row F3 simultaneously, and then the hydrogen filling device in the cabinet storing the hydrogen storage bottles to be filled hydrogen fills the hydrogen storage bottles. And so on, if the hydrogen generators in other rows want to transmit hydrogen to a specified row for assisting in hydrogen filling, they can achieve the goal through the cooperation of the first valve and the second valve, and can accurately realize the transmission of the hydrogen produced by the hydrogen generator to any other specified row.

[0063] Based on the above content, in one embodiment, when all the bottles in the row responsible for any one of the hydrogen generators Z2, Z3, and Z4 are in a full state, it is possible to assist in hydrogen filling for cabinet G1 in row Z1. Similarly, when there are hydrogen storage bottles to be filled in cabinet G13 responsible for by Z4, as long as any one of the hydrogen generators Z1, Z2, and Z3 is in an idle state, it can assist Z4 in filling the hydrogen storage device in cabinet G13. Thus, a hydrogen filling device can be assisted in hydrogen production by up to four hydrogen generators simultaneously, greatly improving the hydrogen filling efficiency.

[0064] For example, as Figure 4 shown, assuming that Z2, Z3, and Z4 are all idle, at this time, it is possible to assist Z1 in filling cabinet G1 in row F1 with empty bottles: M2, M3, and M4 are all switched to not transmit hydrogen to the same row but to other rows, M1 is fully open, row F1 can access the hydrogen produced by Z1 at this time, and can also access the hydrogen produced by Z2, Z3, and Z4. The valve bodies of N1 and N2 are fully open, so that the hydrogen produced by Z2, Z3, and Z4 can all be transmitted to row F1, and then the hydrogen filling device in cabinet G1 fills the hydrogen storage bottles to be filled hydrogen among them.

[0065] In some other embodiments of the present application, a new specific process example of a hydrogen refueling and swapping method based on an APP is also provided to solve the hydrogen swapping problem of hydrogen energy vehicles.

[0069] 4) Click on scan code for hydrogen swapping, scan the QR code on the on-site hydrogen production, refueling and swapping system, and enter the hydrogen swapping confirmation order page. The hydrogen swapping order page displays the hydrogen swapping cabinet site name, hydrogen swapping cabinet address, hydrogen cabinet number, available quantity for swapping, number of empty cabinets, and hydrogen swapping unit price.

[0070] 5) Determine the status of the hydrogen swapping cabinet by scanning the code: whether the device is offline, whether there are full hydrogen bottles, and whether there are empty cabinets.

[0071] 6) Click to confirm payment and activate the on-site hydrogen production, refueling and swapping system to evoke the cashier desk; when the order payment is successful, the system will guide the user to the on-site hydrogen production, refueling and swapping system for hydrogen swapping operations.

[0072] 7) After completing the payment, jump to the in-progress hydrogen swapping page and automatically open the cabinet door of an empty hydrogen storage bottle (empty cabinet); after the cabinet door of the empty hydrogen storage bottle is opened, the user needs to put the hydrogen storage bottle to be refueled into the empty cabinet and manually close the door; the background detects the status of the empty cabinet door. If it is detected that the cabinet door is successfully closed and there is a hydrogen storage bottle inside, the cabinet door of a full hydrogen storage bottle will automatically pop open.

[0073] 8) After the cabinet door of the full hydrogen storage bottle is opened, the user takes away the hydrogen storage bottle and closes the cabinet door. When the background detects that the cabinet door is closed and there is no hydrogen storage bottle, the order is completed.

[0074] 9) The opened cabinet door number is sent by the control system to the control background, and then sent to the front end for display to the user. There is no need for the user to select the opening cabinet door number.

[0075] 10) The background records the user's hydrogen swapping information, including: hydrogen swapping time, hydrogen swapping location, hydrogen swapping quantity, etc. The user can view the previous hydrogen swapping records in the APP.
