[0041] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0042] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the ordinary meanings understood by those with ordinary skills in the field to which the present application belongs.

Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0043] In some embodiments, Figure 1 A schematic diagram of the process of a hydrogen storage system control method is shown. The hydrogen storage system control method can be executed by a corresponding hydrogen storage system control device, and the hydrogen storage system control device can be implemented in a software and / or hardware manner. The hydrogen storage system control device can be deployed on a vehicle or can be deployed to a cloud or server communicating with the vehicle.

[0044] As Figure 1 shown, the hydrogen storage system control method includes the following steps:

[0045] S110. Detect air leakage in the hydrogen pipeline of the on-vehicle hydrogen storage system.

[0046] Among them, the on-vehicle hydrogen storage system is used to store hydrogen and supply hydrogen to the on-vehicle hydrogen fuel cell, so that the on-vehicle hydrogen fuel cell can obtain a continuous supply of fuel, thereby providing energy for the vehicle and enabling the vehicle to operate.

[0047] The hydrogen pipelines of the on-vehicle hydrogen storage system include a hydrogen supply pipeline and a hydrogen refueling pipeline. Among them, the hydrogen supply pipeline refers to the pipeline used to transport hydrogen to the on-vehicle fuel cell, and the hydrogen refueling pipeline refers to the pipeline for refueling the hydrogen storage system with hydrogen. When performing a leak detection, all pipelines of the on-vehicle hydrogen storage system are detected to ensure the comprehensiveness of the detection, and further ensure the safety and reliability of the entire hydrogen storage system.

[0048] In some embodiments, the leak detection of the hydrogen pipelines of the on-vehicle hydrogen storage system can be performed by a hydrogen concentration sensor or a pressure sensor. It can be understood that if a leak occurs in a certain pipeline of the hydrogen storage system, the hydrogen concentration near the outside of the pipeline will increase, and based on this, the leak detection of a certain pipeline can be realized. Optionally, if a leak occurs in a certain pipeline of the hydrogen storage system, the pressure inside the pipeline will change (for example, the pressure inside the pipeline with a leak fault will decrease), and based on this, the leak detection of this pipeline can be realized.

[0049] S120. Cut off the passage between the target pipeline with a leak fault and the hydrogen source.

[0050] Among them, the hydrogen source can include each hydrogen supply unit of the on-vehicle hydrogen storage system and the hydrogen that is supplied to the fuel cell but not consumed by the fuel cell.

[0051] By cutting off the passage between the target pipeline with a leak fault and the hydrogen source, the purpose of preventing hydrogen from leaking through the target pipeline can be achieved, the safety and reliability of the on-vehicle hydrogen storage system can be improved, thereby ensuring the stability of the hydrogen fuel cell vehicle and enhancing the driving experience.

[0052] In particular, in the technical solution of the embodiment of the present application, only the target pipeline with a leak fault is processed, without affecting the other parts of the on-vehicle hydrogen storage system to continue working, so as to further improve the reliability of the on-vehicle hydrogen storage system.

[0053] The hydrogen storage system control method provided by the embodiment of the present application cuts off the passage between the target pipeline with a leak fault and the hydrogen source when detecting a leak fault, rather than controlling the entire hydrogen storage system to shut down. While achieving the purpose of preventing hydrogen from continuing to leak, it also ensures that the other parts of the hydrogen storage system work normally, improves the reliability of the hydrogen storage system, thereby ensuring the stability of the hydrogen fuel cell vehicle and enhancing the driving experience.

[0054] In some embodiments, the hydrogen storage system includes at least two hydrogen supply units, and each hydrogen supply unit supplies hydrogen to the fuel cell through different hydrogen supply pipelines. Refer to Figure 2As shown, taking the number of hydrogen supply units as 2 as an example, the hydrogen storage system includes a hydrogen supply unit 210 and a hydrogen supply unit 220. Among them, the hydrogen supply unit 210 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 211, and the hydrogen supply unit 220 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 221. By setting each hydrogen supply unit to deliver hydrogen to the fuel cell through different hydrogen supply pipelines, the stability and reliability of the on-vehicle hydrogen storage system can be improved. Specifically, assuming that the hydrogen supply unit 210 fails or the hydrogen supply pipeline 211 leaks, the faulty hydrogen supply unit 210 or the hydrogen supply pipeline 211 can be processed, but it will not affect the normal operation of the hydrogen supply unit 220 and the hydrogen supply pipeline 221. In this way, the hydrogen supply unit 220 and the hydrogen supply pipeline 221 can continue to deliver hydrogen to the on-vehicle fuel cell 230, achieving the purpose of improving the stability and reliability of the on-vehicle hydrogen storage system, thereby ensuring the stability of the hydrogen fuel cell vehicle and enhancing the driving experience.

[0055] Optionally, in order to save pipelines, reduce the number of air inlets of the fuel cell, improve airtightness, reduce the overall volume of the on-vehicle hydrogen storage system or improve space utilization, the structure of the on-vehicle hydrogen storage system shown in Figure 3 can also be adopted. Taking the number of hydrogen supply units as 2 as an example, the hydrogen storage system includes a hydrogen supply unit 210 and a hydrogen supply unit 220. Among them, the hydrogen supply unit 210 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 211, and the hydrogen supply unit 220 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 221. Among them, there is a common pipeline section 240 between the hydrogen supply pipeline 211 and the hydrogen supply pipeline 221. The purpose of setting the common pipeline section 240 is to save pipelines, reduce the number of air inlets of the fuel cell, improve airtightness, reduce the overall volume of the on-vehicle hydrogen storage system or improve space utilization. The common pipeline section 240 can be determined according to the actual on-vehicle space. Usually, the common pipeline section 240 corresponds to a pipeline section that is not easily damaged. Due to the particularity of the on-vehicle space, during the bumpy driving of the vehicle, the pipelines in some positions are easily damaged, while the pipelines in some positions are not easily damaged. Therefore, the common pipeline section can be set in a position that is not easily damaged to achieve the purpose of saving pipelines, reducing the number of air inlets of the fuel cell, improving airtightness and reducing costs on the basis of ensuring the safety and stability of the on-vehicle hydrogen storage system.

[0056] When the target pipeline with a leakage failure includes the hydrogen supply pipeline corresponding to the target hydrogen supply unit, control the cut-off of the passage between the target pipeline with a leakage failure and the hydrogen source. For example, if the target pipeline with a leakage failure is the hydrogen supply pipeline 211 corresponding to the hydrogen supply unit 210, then control the cut-off of the passage between the hydrogen supply pipeline 211 and the hydrogen supply unit 210 to prevent the hydrogen gas in the hydrogen supply unit 210 from leaking when flowing through the hydrogen supply pipeline 211, and control the cut-off of the passage between the hydrogen supply pipeline 211 and the fuel cell 230 to prevent the hydrogen gas that is transported by other hydrogen supply units (such as the hydrogen supply unit 220) to the fuel cell 230 but not consumed from flowing back to the hydrogen supply pipeline 211 and leaking. Specifically, reference can be made to Figure 4 a schematic diagram showing the cut-off of a passage as shown. Among them, the passage between the hydrogen supply pipeline 211 and the hydrogen supply unit 210 is cut off by valve A, and the passage between the hydrogen supply pipeline 211 and the fuel cell 230 is cut off by valve B. However, the hydrogen supply unit 220 and the corresponding hydrogen supply pipeline 221 are not affected. Therefore, hydrogen can continue to be supplied to the fuel cell through the hydrogen supply unit 220 and the corresponding hydrogen supply pipeline 221, which can improve the hydrogen supply stability, and further ensure the stability of the hydrogen fuel cell vehicle and enhance the driving experience. Similarly, if the target pipeline with a leakage failure is the hydrogen supply pipeline 221 corresponding to the hydrogen supply unit 220, then control the cut-off of the passage between the hydrogen supply pipeline 221 and the hydrogen supply unit 220 to prevent the hydrogen gas in the hydrogen supply unit 220 from leaking when flowing through the hydrogen supply pipeline 221, and control the cut-off of the passage between the hydrogen supply pipeline 221 and the fuel cell 230 to prevent the hydrogen gas that is transported by other hydrogen supply units (such as the hydrogen supply unit 210) to the fuel cell 230 but not consumed from flowing back to the hydrogen supply pipeline 221 and leaking.

[0057] Reference Figure 5As shown in the figure, if the target pipeline with a leakage failure is the hydrogen supply pipeline 211 corresponding to the hydrogen supply unit 210, then control the passage between the hydrogen supply pipeline 211 and the hydrogen supply unit 210 to be cut off by valve A to prevent the hydrogen gas in the hydrogen supply unit 210 from leaking when flowing through the hydrogen supply pipeline 211, and control the passage between the hydrogen supply pipeline 211 and the fuel cell 230 (specifically, the passage between the common pipeline section 240) to be cut off by valve B to prevent the hydrogen gas entering the common pipeline section 240 from other hydrogen supply units (such as the hydrogen supply unit 220) from flowing back to the hydrogen supply pipeline 211 and leaking. However, the hydrogen supply unit 220 and the corresponding hydrogen supply pipeline 221 are not affected. Therefore, hydrogen can continue to be supplied to the fuel cell through the hydrogen supply unit 220 and the corresponding hydrogen supply pipeline 221, which can improve the hydrogen supply stability, and then ensure the stability of the hydrogen fuel cell vehicle and enhance the driving experience. Similarly, if the target pipeline with a leakage failure is the hydrogen supply pipeline 221 corresponding to the hydrogen supply unit 220, then control the passage between the hydrogen supply pipeline 221 and the hydrogen supply unit 220 to be cut off to prevent the hydrogen gas in the hydrogen supply unit 220 from leaking when flowing through the hydrogen supply pipeline 221, and control the passage between the hydrogen supply pipeline 221 and the common pipeline section 240 to be cut off to prevent the hydrogen gas entering the common pipeline section 240 from other hydrogen supply units (such as the hydrogen supply unit 210) from flowing back to the hydrogen supply pipeline 221 and leaking.

[0058] Generally speaking, when the target pipeline with a leakage failure includes the hydrogen supply pipeline corresponding to the target hydrogen supply unit, control the passage between the target pipeline with a leakage failure and the hydrogen source to be cut off. Specifically, control the first passage between the target hydrogen supply unit and the target pipeline to be cut off, and control the second passage between other hydrogen supply units except the target hydrogen supply unit and the target pipeline to be cut off.

[0059] In some embodiments, the control of cutting off the first passage between the target hydrogen supply unit and the target pipeline and the control of cutting off the second passage between other hydrogen supply units except the target hydrogen supply unit and the target pipeline include:

[0060] Control the first passage to be cut off by the first valve provided on the first passage, and control the second passage to be cut off by the second valve provided on the second passage. The first valve is arranged close to the target hydrogen supply unit. Among them, the specific forms of the first valve and the second valve can be solenoid valves. For example, the first valve and the second valve can be normally open solenoid valves to ensure that hydrogen can pass through smoothly. When it is necessary to cut off the first passage and the second passage, control the first valve and the second valve to close.

[0061] In some embodiments, the hydrogen storage system further includes a pressure reducing unit for reducing the pressure of the hydrogen delivered to the fuel cell to ensure the stability of hydrogen supply. Optionally, the pressure reducing units are provided in one-to-one correspondence with the hydrogen supply units. For example, Figure 6 as shown, taking the number of hydrogen supply units as 2, the hydrogen storage system includes a hydrogen supply unit 210 and a hydrogen supply unit 220. Among them, the hydrogen supply unit 210 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 211 and a pressure reducing unit 212, and the hydrogen supply unit 220 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 221 and a pressure reducing unit 222. In this embodiment, if a leakage fault occurs in the hydrogen supply pipeline 211 between the hydrogen supply unit 210 and the pressure reducing unit 212, it can be carried out in the manner as Figure 7 shown. The passage between the hydrogen supply unit 210 and the pressure reducing unit 212 is cut off by controlling valves A and B. Among them, valve A is arranged at a position close to the hydrogen supply unit 210, and valve B can be arranged on the pipeline close to the pressure reducing unit 212 in front of the pressure reducing unit 212, or on the pipeline behind the pressure reducing unit 212 (for example, it can be at a position close to the pressure reducing unit 212, or at a position close to the fuel cell 230), and can also be integrally arranged with the pressure reducing unit 212.

[0062] In some other embodiments, only one pressure reducing unit is provided in the entire vehicle-mounted hydrogen storage system, that is, each hydrogen supply unit shares a pressure reducing unit, so as to reduce costs. For example, Figure 8 as shown, taking the number of hydrogen supply units as 2, the hydrogen storage system includes a hydrogen supply unit 210 and a hydrogen supply unit 220. Among them, the hydrogen supply unit 210 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 211, a pressure reducing unit 250, and a common pipeline section 240, and the hydrogen supply unit 220 delivers hydrogen to the fuel cell 230 through a hydrogen supply pipeline 221, a pressure reducing unit 250, and a common pipeline section 240. In this embodiment, as Figure 9 shown, if a leakage fault occurs in the hydrogen supply pipeline 211, the passage between the hydrogen supply pipeline 211 and the hydrogen source can be cut off by controlling valves A and B.

[0063] In some embodiments, each hydrogen supply unit is respectively connected to a hydrogen filling port through different hydrogen filling pipelines. For example, Figure 10As shown, taking the number of hydrogen supply units as 2 as an example, the hydrogen storage system includes a hydrogen supply unit 210 and a hydrogen supply unit 220. The hydrogen supply unit 210 supplies hydrogen to the fuel cell 230 through a hydrogen supply pipeline 211, a pressure reduction unit 250, and a common pipeline section 240. The hydrogen supply unit 220 supplies hydrogen to the fuel cell 230 through a hydrogen supply pipeline 221, a pressure reduction unit 250, and a common pipeline section 240. The hydrogen supply unit 210 is connected to a hydrogen filling port 260 through a hydrogen filling pipeline 212, and the hydrogen supply unit 220 is connected to the hydrogen filling port 260 through a hydrogen filling pipeline 222. By setting each hydrogen supply unit to be connected to the hydrogen filling port 260 through different hydrogen filling pipelines, if the hydrogen filling pipeline corresponding to one of the hydrogen supply units is damaged or leaks, the corresponding hydrogen supply unit can be hydrogen-filled through the other hydrogen filling pipeline. This hydrogen supply unit can normally obtain hydrogen and then supply it to the vehicle-mounted fuel cell. Therefore, the hydrogen supply stability of the vehicle-mounted hydrogen storage system can be improved, and the stability of the fuel cell vehicle can be ensured, enhancing the driving experience. In this embodiment, as Figure 11 shown, if a leakage fault occurs in the hydrogen filling pipeline 212 corresponding to the hydrogen supply unit 210, the passage between the hydrogen filling port 260 and the hydrogen filling pipeline 212 is cut off by a valve A near the hydrogen filling port 260, and the passage between the hydrogen supply unit 210 and the hydrogen filling pipeline 212 is cut off by a valve B near the hydrogen supply unit 210 to prevent the residual hydrogen in the hydrogen supply unit 210 from leaking through the hydrogen filling pipeline 212.

[0064] Generally, when the target pipeline with a leakage fault includes any one of the hydrogen filling pipelines, controlling the passage between the target pipeline with a leakage fault and the hydrogen source to be cut off includes: controlling the passage between the target pipeline and the hydrogen filling port to be cut off by a third valve provided on the hydrogen filling pipeline with a leakage fault, and the third valve is provided near the hydrogen filling port.

[0065] In some alternative embodiments, the hydrogen supply unit of the vehicle-mounted hydrogen storage system may specifically be composed of hydrogen storage cylinders. One hydrogen supply unit may include one or more hydrogen storage cylinders, and the connection mode between the hydrogen storage cylinders may be in series or in parallel.

[0066] Taking the vehicle-mounted hydrogen storage system including two hydrogen supply units, and each hydrogen supply unit including one hydrogen storage cylinder as an example, refer to as Figure 12Schematic diagram of the structure of a vehicle-mounted hydrogen storage system, including a first hydrogen storage cylinder 10, a second hydrogen storage cylinder 12, a fuel cell 9, a hydrogen refueling port 3, a first hydrogen cylinder outlet pipe 11 corresponding to the first hydrogen storage cylinder 10, a second hydrogen cylinder outlet pipe 6 corresponding to the second hydrogen storage cylinder 12, a first hydrogen cylinder inlet pipe 1 corresponding to the first hydrogen storage cylinder 10, a second hydrogen cylinder inlet pipe 5 corresponding to the second hydrogen storage cylinder 12, a pressure reducing valve 7, a fuel cell hydrogen supply pipe 8, a tee 4, a hydrogen refueling pipe 2, and a pressure sensor 13. Among them, two pressure sensors 13 are integrated in the tee 4, and these two pressure sensors 13 are respectively used to detect the internal pressure of the first hydrogen cylinder inlet pipe 1 corresponding to the first hydrogen storage cylinder 10 and the second hydrogen cylinder inlet pipe 5 corresponding to the second hydrogen storage cylinder 12. When a leakage fault occurs in the first hydrogen cylinder inlet pipe 1 corresponding to the first hydrogen storage cylinder 10 or the second hydrogen cylinder inlet pipe 5 corresponding to the second hydrogen storage cylinder 12, the detection value of the corresponding pressure sensor 13 will change accordingly. Therefore, whether there is a leakage fault in the first hydrogen cylinder inlet pipe 1 corresponding to the first hydrogen storage cylinder 10 and the second hydrogen cylinder inlet pipe 5 corresponding to the second hydrogen storage cylinder 12 can be detected through the corresponding pressure sensors 13. A pressure sensor 13 is provided at the bottle valve of the first hydrogen storage cylinder 10 or at a position on the first hydrogen cylinder outlet pipe 11 close to the first hydrogen storage cylinder 10 to detect whether there is a leakage fault in the first hydrogen cylinder outlet pipe 11. Specifically, if a leakage fault occurs in the first hydrogen cylinder outlet pipe 11, the pressure inside the first hydrogen cylinder outlet pipe 11 will decrease, and the detection value of the corresponding pressure sensor 13 will change accordingly. Similarly, a pressure sensor 13 is provided at the bottle valve of the second hydrogen storage cylinder 12 or at a position on the second hydrogen cylinder outlet pipe 6 close to the second hydrogen storage cylinder 12 to detect whether there is a leakage fault in the second hydrogen cylinder outlet pipe 6.

[0067] Specifically, a normally closed solenoid valve is integrated on the tee 4 and is only opened when refueling the first hydrogen storage cylinder 10 and the second hydrogen storage cylinder 12. The pressure reducing valve 7 is integrated with two normally open solenoid valves, which are only closed when a leakage fault occurs in the corresponding hydrogen supply pipeline.

[0068] For Figure 12 As shown, there are two hydrogen refueling paths, which are respectively: hydrogen refueling port 3 - hydrogen refueling pipe 2 - tee 4 - first hydrogen cylinder inlet pipe 1 - first hydrogen storage cylinder 10; hydrogen refueling port 3 - hydrogen refueling pipe 2 - tee 4 - second hydrogen cylinder inlet pipe 5 - second hydrogen storage cylinder 12. There are two hydrogen supply paths, which are respectively: first hydrogen storage cylinder 10 - first hydrogen cylinder outlet pipe 11 - pressure reducing valve 7 - fuel cell hydrogen supply pipe 8 - fuel cell 9; second hydrogen storage cylinder 12 - second hydrogen cylinder outlet pipe 6 - pressure reducing valve 7 - fuel cell hydrogen supply pipe 8 - fuel cell 9.

[0069] In some application scenarios, when the first hydrogen cylinder outlet pipe 11 connecting the first hydrogen storage cylinder 10 and the pressure reducing valve 7 is damaged for some reason, the controller of the vehicle-mounted hydrogen storage system can detect abnormal pressure through the pressure sensor 13 on the first hydrogen storage cylinder 10, thereby closing the cylinder valve of the first hydrogen storage cylinder 10 to prevent hydrogen leakage from the first hydrogen storage cylinder 10, and controlling the solenoid valve corresponding to the first hydrogen cylinder outlet pipe 11 in the pressure reducing valve 7 to close, so as to prevent hydrogen in the second hydrogen storage cylinder 12 from flowing into the first hydrogen cylinder outlet pipe 11 through the pressure reducing valve 7 and being leaked. The hydrogen in the damaged pipeline is very little and will be diluted quickly. To improve safety, a hydrogen concentration sensor is set on the outer side of the corresponding pipeline. The hydrogen concentration sensor will monitor in real time. If there is no alarm within a certain period of time, it proves that the hydrogen concentration is low and the environment is safe. The customer can start the vehicle. At this time, the cylinder valve of the second hydrogen storage cylinder 12 is controlled to open, and hydrogen can enter the fuel cell 9 through the second hydrogen cylinder outlet pipe 6, the pressure reducing valve 7, and the fuel cell hydrogen supply pipe 8, enabling the vehicle to continue working. On the contrary, if there is a problem with the second hydrogen cylinder outlet pipe 6 of the second hydrogen storage cylinder 12, the vehicle-mounted hydrogen storage system can supply hydrogen to the fuel cell 9 through the first hydrogen storage cylinder 10 - the first hydrogen cylinder outlet pipe 11 - the pressure reducing valve 7 - the fuel cell hydrogen supply pipe 8, and still ensure that the vehicle continues to work. That is, the leak detection of the hydrogen pipeline can be carried out through the pressure sensor or the hydrogen concentration sensor associated with the hydrogen pipeline.

[0070] Correspondingly, reference can be made to Figure 13Schematic flow diagram of a control method, specifically including: If a leakage fault occurs in the first hydrogen cylinder outlet pipe, the detection value of the corresponding pressure sensor is abnormal. When the controller of the vehicle-mounted hydrogen storage system detects the abnormality, it controls the closing of the bottle valves of the first hydrogen storage cylinder and the second hydrogen storage cylinder and the closing of the corresponding solenoid valve in the pressure reducing valve, and detects the concentration of the leaked hydrogen through the corresponding hydrogen concentration sensor. If the hydrogen concentration is low, it means that the environment is safe at this time. The controller of the vehicle-mounted hydrogen storage system controls the opening of the bottle valve of the second hydrogen storage cylinder, and continues to supply hydrogen to the fuel cell through the second hydrogen storage cylinder - the second hydrogen cylinder outlet pipe - the pressure reducing valve - the fuel cell hydrogen supply pipe. On the basis of ensuring safety, the hydrogen supply stability is improved, and then the operation stability of the hydrogen fuel cell vehicle is ensured, and the driving experience is enhanced. Similarly, when a leakage fault occurs in the second hydrogen cylinder outlet pipe, the detection value of the corresponding pressure sensor is abnormal. When the controller of the vehicle-mounted hydrogen storage system detects the abnormality, it controls the closing of the bottle valves of the first hydrogen storage cylinder and the second hydrogen storage cylinder and the closing of the corresponding solenoid valve in the pressure reducing valve, and detects the concentration of the leaked hydrogen through the corresponding hydrogen concentration sensor. If the hydrogen concentration is low, it means that the environment is safe at this time. The controller of the vehicle-mounted hydrogen storage system controls the opening of the bottle valve of the first hydrogen storage cylinder, and continues to supply hydrogen to the fuel cell through the first hydrogen storage cylinder - the first hydrogen cylinder outlet pipe - the pressure reducing valve - the fuel cell hydrogen supply pipe. On the basis of ensuring safety, the hydrogen supply stability is improved, and then the operation stability of the hydrogen fuel cell vehicle is ensured, and the driving experience is enhanced.

[0071] In some other application scenarios, when the first hydrogen cylinder inlet pipe 1 connecting the first hydrogen storage cylinder 10 and the hydrogen refueling port 3 is damaged for some reason, the controller of the hydrogen storage system can detect the abnormal pressure through the pressure sensor 13 on the three-way valve 4, and then control the solenoid valve on the three-way valve 4 to close the first hydrogen cylinder inlet pipe 1 (a check valve is provided inside the bottle valve of the first hydrogen storage cylinder 10 connected to the first hydrogen cylinder inlet pipe 1, and hydrogen leakage will not occur when the pipeline is damaged). If the hydrogen in the damaged pipeline is very little and will be diluted quickly, the hydrogen concentration sensor will monitor it in real time. If there is no alarm within a certain period of time, it proves that the environment is safe and the customer can start the vehicle. At this time, when refueling hydrogen, the hydrogen enters the second hydrogen storage cylinder 12 through the hydrogen refueling port 3 - the three-way valve 4 - the second hydrogen cylinder inlet pipe 5. Subsequently, the bottle valve of the first hydrogen storage cylinder 10 is closed and the bottle valve of the second hydrogen storage cylinder 12 is opened, and the fuel cell can still obtain stable hydrogen and the vehicle can still continue to work. On the contrary, if there is a problem with the second hydrogen cylinder inlet pipe 5 of the second hydrogen storage cylinder 12, hydrogen is added and supplied through the first hydrogen storage cylinder 10, and the vehicle can still be ensured to continue working.

[0072] Correspondingly, it can be referred to as Figure 14Schematic flow diagram of a control method, specifically including: If a leakage fault occurs in the first hydrogen cylinder inlet pipe, the detected value of the corresponding pressure sensor will be abnormal. When the controller of the vehicle-mounted hydrogen storage system detects the abnormal detected value of the pressure sensor, it controls the bottle valves of the first hydrogen storage cylinder and the second hydrogen storage cylinder to close. When it is detected by the hydrogen concentration sensor that the environment is safe, it controls the bottle valve of the second hydrogen storage cylinder to open, and hydrogen is added to the second hydrogen storage cylinder through the hydrogen filling port - three-way - second hydrogen cylinder inlet pipe, and then hydrogen is supplied to the fuel cell through the second hydrogen storage cylinder - second hydrogen cylinder outlet pipe - pressure reducing valve - fuel cell hydrogen supply pipe. Similarly, if a leakage fault occurs in the second hydrogen cylinder inlet pipe, the detected value of the corresponding pressure sensor will be abnormal. When the controller of the vehicle-mounted hydrogen storage system detects the abnormal detected value of the pressure sensor, it controls the bottle valves of the first hydrogen storage cylinder and the second hydrogen storage cylinder to close. When it is detected by the hydrogen concentration sensor that the environment is safe, it controls the bottle valve of the first hydrogen storage cylinder to open, and hydrogen is added to the first hydrogen storage cylinder through the hydrogen filling port - three-way - first hydrogen cylinder inlet pipe, and then hydrogen is supplied to the fuel cell through the first hydrogen storage cylinder - first hydrogen cylinder outlet pipe - pressure reducing valve - fuel cell hydrogen supply pipe.

[0073] Specifically, since the positions of the hydrogen storage cylinders and the bottle valves are generally relatively high and are blocked by the longitudinal body beam on the side, they are basically not likely to be touched and can withstand a certain impact. However, the pipeline layout is at a relatively lower position and is more likely to be damaged. Therefore, the solution of this application specifically addresses the situation where the pipeline is damaged. This solution is explained by taking two hydrogen storage cylinders as an example. More than two hydrogen storage cylinders can be connected through pipelines, gas rails, etc. under the principle of this control method. As long as it is this control method, any number is within the protection scope. In this solution, the positions of the hydrogen storage cylinders can be swapped with each other, and the connection positions of pipelines, gas rails, pressure reducing valves, etc. can all be interchanged and adjusted according to the actual situation. All connection methods are within the protection scope.

[0074] Generally speaking, the solution of the embodiment of this application integrates a solenoid valve on the pressure reducing valve (the solenoid valve can also be connected to the pipeline). In this way, it not only ensures the normal hydrogen supply of several hydrogen storage cylinders, but also avoids the problem of leakage caused by the pipelines of other hydrogen storage cylinders passing through the passage when one of the hydrogen supply pipes is damaged. By controlling each hydrogen storage cylinder separately, it is realized that when there is a problem with the pipeline and the bottle valve of one of the hydrogen cylinders, the vehicle can still be normally hydrogenated and continue to work, improving the customer experience and reducing the risk of vehicle breakdown.

[0075] It should be noted that the method of the embodiment of this application can be executed by a single device, such as a computer or a server, etc. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In this case of a distributed scenario, one of these multiple devices can only execute one or more steps of the method of the embodiment of this application, and these multiple devices will interact with each other to complete the described method.

[0076] It should be noted that some embodiments of the present application have been described above. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the above embodiments and still achieve the desired result. Additionally, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown to achieve the desired result. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0077] Based on the same inventive concept, corresponding to the method of any of the above embodiments, the present application further provides a hydrogen storage system control device. Referring to Figure 15 , the hydrogen storage system control device includes: a detection module 1510 for detecting air leakage in the hydrogen pipeline of the vehicle-mounted hydrogen storage system; a control module 1520 for controlling the cut-off of the passage between the target pipeline with air leakage fault and the hydrogen source.

[0078] Further, the detection module 1510 is specifically configured to: detect air leakage in the hydrogen pipeline through a pressure sensor or a hydrogen concentration sensor associated with the hydrogen pipeline.

[0079] Further, the hydrogen storage system includes at least two hydrogen supply units, and each hydrogen supply unit supplies hydrogen to the fuel cell through a different hydrogen supply pipeline. When the target pipeline with air leakage fault includes the hydrogen supply pipeline corresponding to the target hydrogen supply unit, the control module 1520 includes a control unit, and the control unit is configured to: control the cut-off of the first passage between the target hydrogen supply unit and the target pipeline, and control the cut-off of the second passage between other hydrogen supply units except the target hydrogen supply unit and the target pipeline.

[0080] Further, the control unit is specifically configured to control the cut-off of the first passage through a first valve provided on the first passage, and control the cut-off of the second passage through a second valve provided on the second passage. The first valve is provided close to the target hydrogen supply unit.

[0081] Further, the hydrogen storage system further includes a pressure reducing unit for reducing the pressure of the hydrogen supplied to the fuel cell.

[0082] Further, the hydrogen supply pipelines respectively corresponding to each hydrogen supply unit are all connected to the first end of the pressure reducing unit, and the second end of the pressure reducing unit is connected to the fuel cell through a pipeline.

[0083] Further, each hydrogen supply unit is respectively connected to the hydrogenation port through different hydrogenation pipelines. When the target pipeline with a leakage fault includes any one of the hydrogenation pipelines, the control module 1520 is specifically configured to: cut off the passage between the target pipeline and the hydrogenation port through a third valve provided on the hydrogenation pipeline with the leakage fault, and the third valve is arranged close to the hydrogenation port.

[0084] When detecting a leakage fault, the hydrogen storage system control device provided by the embodiment of the present application cuts off the passage between the target pipeline with the leakage fault and the hydrogen source, rather than controlling the entire hydrogen storage system to shut down. While achieving the purpose of preventing hydrogen from continuing to leak, it also ensures that other parts of the hydrogen storage system work properly, improves the reliability of the hydrogen storage system, and thus ensures the stability of the hydrogen fuel cell vehicle and enhances the driving experience.
