Description

Technical Field

[0001] This application belongs to the field of hydrogen storage system technology, and specifically relates to an activation control method, processor and hydrogen storage system for a hydrogen storage system. Background Technology

[0002] Solid hydrogen storage powders can become deactivated due to contact with air and other factors before preparation and bottling, leading to a decrease in hydrogen absorption and desorption performance. Therefore, after loading solid hydrogen storage powders into a hydrogen storage device, activation is required to achieve the designed hydrogen storage performance. Furthermore, after long-term use, activation is also necessary to restore the internal hydrogen storage powder and the overall hydrogen storage performance of the system. After each hydrogen use, the device needs to be precisely refilled with the required mass of hydrogen using a hydrogen refueling device. Currently, existing activation equipment for hydrogen storage devices requires manual operation, which is time-consuming and labor-intensive. The manual operation of critical steps also poses safety risks due to human error. In addition, existing methods for regulating the internal temperature of hydrogen storage devices generally suffer from uneven temperature regulation, long processing times, high energy consumption, and low temperature regulation efficiency.

[0034] Step S103: Control the hydrogen source 1 and the hydrogen filling pipeline module 2 to cooperate in performing the hydrogen filling operation.

[0035] In one embodiment of this application, the hydrogen filling pipeline module 2 includes a first hydrogen filling pipeline unit 201 and a second hydrogen filling pipeline unit 202 connected in parallel and connected at both ends to a hydrogen source 1 and a hydrogen storage device 5, respectively. The first hydrogen filling pipeline 2012 of the first hydrogen filling pipeline unit 201 is equipped with a first flow detection element 2011 for detecting the flow rate of hydrogen in the first hydrogen filling pipeline unit 201. The second hydrogen filling pipeline 2022 of the second hydrogen filling pipeline unit 202 is equipped with a volume chamber 2021. The cross-sectional areas of both the first and second hydrogen filling pipelines are smaller than the minimum flow cross-sectional area of ​​the volume chamber 2021. Step S103, controlling the hydrogen source 1 and the hydrogen filling pipeline module 2 to cooperate in performing the hydrogen filling operation, further includes the following steps: Step S1031: Control the hydrogen source 1, the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202 to cooperate in performing a staged hydrogen charging operation, so that when the flow rate of hydrogen flowing into the hydrogen storage device 5 is greater than the maximum range of the first flow detection element 2011, hydrogen is delivered through the second hydrogen charging pipeline unit 202, and when the flow rate of hydrogen flowing into the hydrogen storage device 5 is less than or equal to the maximum range of the first flow detection element 2011, hydrogen is delivered through the first hydrogen charging pipeline unit 201.

[0036] In one embodiment of this application, step S1031, which controls the hydrogen source 1, the first hydrogen charging pipeline unit 201, and the second hydrogen charging pipeline unit 202 to cooperate in performing a staged hydrogen charging operation, further includes steps S201-S205, wherein: Step S201: Control the first hydrogen charging pipeline unit 201 to the off state.

[0037] Specifically, in step S201, when the processor 7 controls both the first switching valve 2013 and the second switching valve 2014 to be in the closed state, the first hydrogen charging pipeline 2012 is cut off, and the hydrogen provided by the hydrogen source 1 cannot be delivered to the hydrogen storage device 5 through the first hydrogen charging pipeline 2012.

[0038] Step S202: Control the second hydrogen charging pipeline unit 202 to transport the hydrogen provided by the hydrogen source 1 to the hydrogen storage device 5.

[0039] Specifically, in step S202, the processor 7 controls the hydrogen source 1 to release hydrogen gas to the outside, and at the same time controls the first switch valve 2013 and the second switch valve 2014 to open, and the second hydrogen charging pipeline 2022 to be connected, so that the hydrogen gas provided by the hydrogen source 1 is transported to the hydrogen storage device 5 through the second hydrogen charging pipeline 2022.

[0040] Furthermore, the first hydrogen charging pipeline unit 201 also includes: Pressure regulating component 2016 is disposed on the first hydrogen charging pipeline 2012 and located between the first switching valve 2013 and the hydrogen source 1, and is used to regulate the pressure of hydrogen entering the first hydrogen charging pipeline 2012. The first pressure detection element 2017 is installed on the first hydrogen charging pipeline 2012 and located between the pressure regulating element 2016 and the first switching valve 2013, and is used to detect the pressure of the hydrogen flowing out from the outlet end of the pressure regulating element 2016. The second pressure detection element 2018 is installed on the first hydrogen charging pipeline 2012 and located between the hydrogen storage device 5 and the eighth switch valve 2015, and is used to detect the pressure of hydrogen flowing into the hydrogen storage device 5.

[0041] Specifically, in this embodiment, the pressure regulating component 2016 can be selected as a pressure regulating valve, and the first pressure detection component 2017 and the second pressure detection component 2018 can both be selected as pressure sensors. The first pressure detection component 2017, the second pressure detection component 2018, and the processor 7 are all communicatively connected to the processor 7. When hydrogen is charged into the hydrogen storage device 5 through the first hydrogen charging pipeline 2012, the processor 7 controls the first switching valve 2013, the second switching valve 2014, and the eighth switching valve 2015 to open. When hydrogen is charged into the hydrogen storage device 5 through the second hydrogen charging pipeline 2022, in addition to controlling the third switching valve 2023 and the fourth switching valve 2024 to open, the processor 7 also controls the eighth switching valve 2015 to open. Furthermore, in step S202, the processor 7 also controls the pressure regulator 2016 to adjust the pressure based on the preset hydrogen charging pressure until the pressure of the hydrogen flowing out of the outlet of the pressure regulator 2016 is equal to the preset hydrogen charging pressure. This controls the first pressure detector 2017 to detect the adjustment result of the pressure regulator 2016, which helps improve the accuracy of the adjustment result of the pressure regulator 2016 and the hydrogen flow rate measurement. The second pressure detector 2018 detects the pressure of the hydrogen about to enter the hydrogen storage device 5, further ensuring that the pressure of the hydrogen entering the hydrogen storage device 5 is equal to the preset hydrogen charging pressure. Only when the pressure detected by the first pressure detector 2017 and the pressure detected by the volume chamber pressure detector 2025 (i.e., the first pressure) are both consistent with the preset hydrogen charging pressure, is the fourth switch valve 2024 opened and the third switch valve 2023 closed. This setting helps further improve the accuracy of the hydrogen flow rate measurement in the hydrogen storage device 5.

[0042] In this embodiment, step S202, controlling the second hydrogen charging pipeline unit 202 to transport the hydrogen provided by the hydrogen source 1 to the hydrogen storage device 5, further includes steps S301-S304, wherein: Step S301: Control the pipeline section between the upper volume chamber 2021 of the second hydrogen charging pipeline unit 202 and the hydrogen storage device 5 to be in a cut-off state, and control the pipeline section between the upper volume chamber 2021 of the second hydrogen charging pipeline unit 202 and the hydrogen source 1 to be in a conductive state. Step S302: Control the hydrogen source 1 to supply hydrogen to the volume chamber 2021 until the first pressure of the hydrogen in the volume chamber 2021 reaches the preset hydrogen filling pressure; Step S303: Control the pipeline section between the upper volume chamber 2021 of the second hydrogen charging pipeline unit 202 and the hydrogen source 1 to be in a cut-off state; Step S304: Control the pipeline section between the volume chamber 2021 of the second hydrogen charging pipeline unit 202 and the hydrogen storage device 5 to be in a conductive state so that the hydrogen in the volume chamber 2021 flows into the hydrogen storage device 5.

[0043] Specifically, in this embodiment, when the operator puts the hydrogen storage system into activation mode through the operation input device 8, a preset hydrogen charging pressure is also preset through the operation input device 8, and the operation input device 8 sends the preset hydrogen charging pressure to the processor 7. The volume chamber 2021 is also equipped with a volume chamber pressure detection device 2025 for detecting the pressure of hydrogen inside the volume chamber 2021. The volume chamber pressure detection device 2025 is communicatively connected to the processor 7. After step S201 is executed, the processor 7 first controls the fourth switch valve 2024 to close and the third switch valve 2023 to open, so that hydrogen first enters the volume chamber 2021 and accumulates in the volume chamber 2021. The processor 7 controls the volume chamber pressure detection device 2025 to detect the first pressure of hydrogen in the volume chamber 2021 in real time and sends the first pressure to the processor 7. The processor 7 compares the first pressure with the preset hydrogen charging pressure. When the first pressure does not reach the preset hydrogen charging pressure, the fourth switch valve 2024 continues to close and the third switch valve 2023 continues to open, and hydrogen continues to enter the volume chamber 2021. When the first pressure reaches the preset hydrogen charging pressure, the processor 7 controls the fourth switch valve 2024 to open and the third switch valve 2023 to close, so that the hydrogen in the volume chamber 2021 flows into the hydrogen storage device 5. The above configuration ensures that the volume chamber 2021 is filled with hydrogen before being supplied to the hydrogen storage device 5. This prevents the inflow and outflow ends of the volume chamber 2021 from opening simultaneously, which would result in an excessively high rate of hydrogen flowing out of the volume chamber 2021, leading to a smaller amount of hydrogen in the volume chamber 2021 and affecting the accuracy of the detection results of the volume chamber flow detection module.

[0044] In one embodiment of this application, during the process of hydrogen flowing from the volume chamber 2021 into the hydrogen storage device 5, the real-time hydrogen charging flow rate of the hydrogen storage device 5 is obtained according to the following method: Step S401: Obtain the real-time hydrogen charging pressure, volume of volume chamber 2021, and real-time hydrogen charging temperature of volume chamber 2021; Step S402: Calculate the real-time hydrogen charging flow rate based on the real-time hydrogen charging pressure, volume, and real-time hydrogen charging temperature.

[0045] Specifically, in this embodiment, the volumetric flow detection module includes a volumetric pressure detection element 2025 and a first temperature detection element 2026. The volumetric pressure detection element 2025 is disposed on the volumetric chamber 2021 and is used to detect the pressure of hydrogen inside the volumetric chamber 2021; the first temperature detection element 2026 is disposed on the volumetric chamber 2021 and is used to detect the temperature of hydrogen inside the volumetric chamber 2021. The volumetric pressure detection element 2025 can be selected as a pressure sensor, and the first temperature detection element 2026 can be selected as a temperature sensor. Both the volumetric pressure detection element 2025 and the first temperature detection element 2026 are communicatively connected to the processor 7. When hydrogen is supplied through the second hydrogen charging pipeline 2022, the volumetric pressure detection element 2025 sends its detection result to the processor 7 after detecting the pressure of hydrogen inside the volumetric chamber 2021, and the first temperature detection element 2026 sends its detection result to the processor 7 after detecting the temperature of hydrogen inside the volumetric chamber 2021. The processor 7 can determine the flow rate of hydrogen inside the volume chamber 2021 based on the pressure detected by the volume chamber pressure sensor 2025 and the temperature detected by the first temperature sensor 2026. That is, the processor 7 can calculate the flow rate of hydrogen inside the volume chamber 2021 according to the following formula: (1) in, The flow rate of hydrogen inside the volumetric chamber 2021 (in this embodiment, the flow rate of hydrogen inside the volumetric chamber 2021 refers to the volumetric flow rate of hydrogen inside the volumetric chamber 2021), in L / min; This represents the molar volume of hydrogen gas, expressed in L / mol. The pressure of hydrogen gas inside volumetric chamber 2021 is expressed in Pa. The volume of the 2021 volume chamber is expressed in liters (L). This is the universal gas constant, with units of J / (mol·K); The temperature of the hydrogen gas inside volume chamber 2021 is expressed in Kelvin (K).

[0046] The above-mentioned method for measuring the flow rate of hydrogen inside the volume chamber 2021, when used in conjunction with the volume chamber 2021, can achieve any flow rate of hydrogen, which is beneficial to further expand the applicability of the volume chamber flow detection module and the hydrogen flow monitoring device.

[0047] In another embodiment of this application, during the process of hydrogen flowing from the volume chamber 2021 into the hydrogen storage device 5, the real-time hydrogen charging flow rate of the hydrogen storage device 5 is obtained according to the following method: Step S501: Obtain the mass of hydrogen gas inside volume chamber 2021; Step S502: Calculate the real-time hydrogen charging flow rate based on the mass of hydrogen inside the volume chamber 2021.

[0048] Specifically, in this embodiment, the volumetric flow detection module includes a mass detection element. This mass detection element is located at the bottom of the volumetric chamber 2021 and is used to measure the mass of hydrogen inside the volumetric chamber 2021. The mass detection element can be a mass sensor and is communicatively connected to the processor 7. When hydrogen is supplied to the hydrogen storage device 5 through the second hydrogen filling pipeline 2022, the mass detection element sends its detection result to the processor 7 after detecting the mass of hydrogen inside the volumetric chamber 2021. The processor 7 can determine the mass of hydrogen inside the volumetric chamber 2021 based on the temperature detected by the mass detection element. That is, the processor 7 can calculate the flow rate of hydrogen inside the volumetric chamber 2021 according to the following formula: (2) in, The unit is kg / s; The mass of hydrogen inside volume chamber 2021 is expressed in kg.

[0050] (3) in, The flow rate of hydrogen inside volumetric chamber 2021 (in this embodiment, the flow rate of hydrogen inside volumetric chamber 2021 refers to the volumetric flow rate of hydrogen inside volumetric chamber 2021), in m³ / s. 3 / s; This refers to the density of hydrogen gas, expressed in kg / m³. 3 .

[0052] The above-mentioned method for measuring the flow rate of hydrogen inside the volumetric chamber 2021, when used in conjunction with the volumetric chamber 2021, can avoid indirect errors, which is beneficial to further improve the measurement accuracy of the flow rate of hydrogen inside the volumetric chamber 2021, and has the advantage of high reliability for long-term use.

[0053] Step S203: During the process of hydrogen flowing into the hydrogen storage device 5, obtain the real-time hydrogen charging flow rate of the hydrogen storage device 5; Step S204: When the real-time hydrogen charging flow rate is less than or equal to the maximum range of the first flow detection element 2011, control the second hydrogen charging pipeline unit 202 to shut off and control the first hydrogen charging pipeline unit 201 to transport the hydrogen provided by the hydrogen source 1 to the hydrogen storage device 5.

[0054] Specifically, during the process of hydrogen flowing into the hydrogen storage device 5 through the second hydrogen filling pipeline 2022, the volumetric flow detection module detects the hydrogen flow rate in the volumetric chamber 2021 in real time. In this embodiment, when hydrogen is supplied to the hydrogen storage device 5 through the second hydrogen filling pipeline 2022, the hydrogen flow rate detected by the volumetric flow detection module in real time is consistent with the real-time hydrogen filling flow rate of the hydrogen storage device 5. After detection, the volumetric flow detection module sends the detected hydrogen flow rate to the processor 7. The processor 7 then compares the above-mentioned hydrogen flow rate with the maximum range of the pre-stored first flow detection element 2011 (the maximum range of the first flow detection element 2011 in this embodiment). The range can be pre-input into the processor 7 by the operator through the operation input device 8. If the hydrogen flow rate is greater than the maximum range of the first flow detection device 2011 (i.e., the real-time hydrogen charging flow rate is greater than the maximum range of the first flow detection device 2011), the fourth switch valve 2024 continues to open; if the hydrogen flow rate is less than or equal to the maximum range of the first flow detection device 2011, the fourth switch valve 2024 is closed, and the first switch valve 2013 and the second switch valve 2014 are opened, the first hydrogen charging pipeline 2012 is connected, and the hydrogen provided by the hydrogen source 1 can be transported to the hydrogen storage device 5 through the first hydrogen charging pipeline 2012.

[0055] The above setup enables accurate measurement of hydrogen delivered to the hydrogen storage device 5 under different flow rates. Specifically, when the flow rate of hydrogen to the hydrogen storage device 5 exceeds the maximum range of the first flow detection element 2011, hydrogen is delivered through the second hydrogen filling pipeline unit 202. The flow rate of hydrogen passing through the volume chamber 2021 is accurately measured using the volume chamber flow detection module. Since the cross-sectional areas of both the first and second hydrogen filling pipelines 2012 and 2022 are smaller than the minimum flow cross-sectional area of ​​the volume chamber 2021, the gas flow capacity of the volume chamber 2021 is greater than that of the first filling pipeline. Based on the hydrogen pipeline 2012 and the second hydrogen charging pipeline 2022, when the flow rate of hydrogen to the hydrogen storage device 5 is less than or equal to the maximum range of the first flow detection element 2011, hydrogen is transported through the first hydrogen charging pipeline unit 201. The first flow detection element 2011 is used to accurately measure the flow rate of hydrogen passing through the first hydrogen charging pipeline unit 201, so as to realize the accurate measurement of hydrogen flow rate at any time during the hydrogen charging process of the hydrogen storage device 5, ensuring the accuracy of hydrogen measurement when charging the hydrogen storage device 5, and avoiding the situation of large hydrogen quantity error when charging hydrogen into the hydrogen storage device 5.

[0056] Step S205: When it is confirmed that the hydrogen storage device 5 is full, control the hydrogen source 1 and the first hydrogen charging pipeline unit 201 to cooperate in stopping the staged hydrogen charging operation.

[0057] Specifically, when hydrogen is supplied to the hydrogen storage device 5 through the first hydrogen charging pipeline 2012, the first flow detection element 2011 detects the flow rate of hydrogen in the first hydrogen charging pipeline 2012 in real time and sends the detection value to the processor 7. After hydrogen can no longer enter the interior of the hydrogen storage device 5, the hydrogen stops flowing in the first hydrogen filling pipeline 2012, and the detection result of the first flow detection device 2011 is 0. Further, after step S202 begins, the processor 7 starts to accumulate time until the detection result of the first flow detection device 2011 is 0, at which point the processor 7 stops accumulating time. Then, the processor 7 compares the accumulated time with the preset pressure holding time (in this embodiment, the preset pressure holding time can be pre-input into the processor 7 by the operator through the operation input device 8). If the accumulated time reaches the preset pressure holding time, it can be determined that the hydrogen storage device 5 is full (that is, in this embodiment, when the detection result of the first flow detection device 2011 is 0 and the accumulated time reaches the preset pressure holding time, it is determined that the hydrogen storage device 5 is full). Then, the processor 7 controls the first switching valve 2013 and the second switching valve 2014 to close, controlling the hydrogen source 1 to stop releasing hydrogen.

[0058] Step S104: After the hydrogen charging operation is completed, obtain the total mass of hydrogen charged into the hydrogen storage device 5.

[0059] Specifically, during step S202, the processor 7 calculates the first hydrogen charging mass of the hydrogen storage device 5 (i.e., the mass of hydrogen gas charged into the hydrogen storage device 5 through the second hydrogen charging pipeline 2022) based on the following formula: (4) in, The first hydrogen charge mass is expressed in kg. This refers to the real-time hydrogen flow rate detected by the volumetric chamber flow detection module in hydrogen charging mode, expressed in m³ / s. 3 / s.

[0061] During step S204, the processor 7 calculates the second hydrogen charging mass of the hydrogen storage device 5 (i.e., the mass of hydrogen gas charged into the hydrogen storage device 5 through the first hydrogen charging pipeline 2012) based on the following formula: (5) in, The second hydrogen charge mass is expressed in kg. The flow rate of hydrogen detected by the first flow sensor 2011, in meters per second (m³). 3 / s.

[0063] M1= + (6) Where M1 is the total mass of hydrogen charged, in kg.

[0064] Step S105: Control the venting pipeline module 4 and the hydrogen charging pipeline module 2 to cooperate in performing the second venting operation, so as to depressurize the hydrogen charging pipeline module 2 again.

[0065] Specifically, in step S105, the processor 7 controls the first switching valve 2013, the third switching valve 2023, and the eighth switching valve 2015 to close, and controls the second switching valve 2014, the fourth switching valve 2024, the fifth switching valve 4012, the sixth switching valve 4022, and the seventh switching valve 602 to open, thereby realizing the second venting operation to depressurize the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202 again. The above settings are conducive to further improving the safety of the hydrogen storage system.

[0066] Step S106: Control the hydrogen charging pipeline module 2 and the venting pipeline module 4 to cooperate in performing the hydrogen release operation.

[0067] In one embodiment of this application, the venting pipeline module 4 includes a first venting pipeline unit 401 and a second venting pipeline unit 402 respectively connected to the second hydrogen charging pipeline unit 202 and the first hydrogen charging pipeline unit 201. Step S106, controlling the hydrogen charging pipeline module 2 and the venting pipeline module 4 to cooperate in performing the hydrogen release operation, further includes the following steps: Step S1061: Control the first hydrogen charging pipeline unit 201, the second hydrogen charging pipeline unit 202, the first venting pipeline unit 401, and the second venting pipeline unit 402 to cooperate in performing a staged hydrogen release operation, so that the second hydrogen charging pipeline unit 202 and the first venting pipeline unit 401 cooperate in supplying hydrogen to the outside when the flow rate of hydrogen flowing out of the hydrogen storage device 5 is greater than the maximum capacity, and so that at least a portion of the first hydrogen charging pipeline unit 201 and the second venting pipeline unit 402 cooperate in supplying hydrogen to the outside when the flow rate of hydrogen flowing out of the hydrogen storage device 5 is less than or equal to the maximum capacity.

[0068] In one embodiment of this application, step S1061, which controls the first hydrogen charging pipeline unit 201, the second hydrogen charging pipeline unit 202, the first venting pipeline unit 401, and the second venting pipeline unit 402 to cooperate in performing a staged hydrogen release operation, further includes steps S601-S604, wherein: Step S601: Control the first hydrogen charging pipeline unit 201 and the first discharge pipeline unit 401 to shut down.

[0069] Specifically, in step S601, when the processor 7 controls the first switching valve 2013, the second switching valve 2014 and the fifth switching valve 4012 to be in the closed state, the first hydrogen charging pipeline 2012 and the first venting pipeline 4011 are cut off, and the hydrogen gas released by the hydrogen storage device 5 cannot be discharged to the outside through the first venting pipeline 4011 (such as being discharged to an external hydrogen-using component).

[0070] Step S602: Control the second hydrogen charging pipeline unit 202 and the second discharge pipeline unit 402 to cooperate with each other to discharge the hydrogen gas released by the hydrogen storage device 5 to the outside.

[0071] Specifically, in step S602, the processor 7 controls the third switch valve 2023 to close and controls the fourth switch valve 2024 and the sixth switch valve 4022 to open (when the second end of the second hydrogen charging pipeline 2022 is connected to the first hydrogen charging pipeline 2012, the processor 7 controls the eighth switch valve 2015 to open). The hydrogen gas released by the hydrogen storage device 5 passes through the second hydrogen charging pipeline 2022 and enters the second discharge pipeline 4021 to be discharged outward (such as to an external hydrogen-using component).

[0072] Step S603: During the process of hydrogen flowing out of the hydrogen storage device 5 into the volume chamber 2021, the real-time hydrogen release flow rate of the hydrogen storage device 5 is obtained.

[0073] In one embodiment of this application, during the process of hydrogen gas released from the hydrogen storage device 5 being discharged outward through the second hydrogen charging pipeline unit 202 and the second discharge pipeline unit 402, the real-time hydrogen discharge flow rate of the hydrogen storage device 5 is obtained according to the following method: Step S701: Obtain the real-time hydrogen release pressure, volume of volume chamber 2021, and real-time hydrogen release temperature within volume chamber 2021; Step S702: Calculate the real-time hydrogen release flow rate based on the real-time hydrogen release pressure, volume, and real-time hydrogen release temperature.

[0074] Specifically, during the hydrogen release phase and when the volume chamber flow detection module includes a volume chamber pressure detection element 2025 and a first temperature detection element 2026, the processor 7 can calculate the flow rate of hydrogen inside the volume chamber 2021 during the hydrogen release phase based on the detection results of the volume chamber pressure detection element 2025 and the first temperature detection element 2026 and formula (1). In this embodiment, the hydrogen flow rate detected in real time by the volume chamber flow detection module is consistent with the real-time hydrogen release flow rate of the hydrogen storage device 5.

[0075] In another embodiment of this application, during the hydrogen release phase and when the volume chamber flow detection module includes a mass detection element, the processor 7 can calculate the flow rate of hydrogen inside the volume chamber 2021 under the hydrogen release mode based on the detection result of the mass detection element and formulas (2) and (3).

[0076] Step S604: When the real-time hydrogen release flow rate is less than or equal to the maximum range of the second flow detection element 4013, control the second hydrogen charging pipeline unit 202 and the second discharge pipeline unit 402 to shut off and control the first hydrogen charging pipeline unit 201 and the first discharge pipeline unit 401 to cooperate with each other to discharge the hydrogen released from the hydrogen storage device 5 to the outside until the hydrogen storage device 5 is emptied.

[0077] Specifically, during the process of hydrogen gas released from the hydrogen storage device 5 being discharged outward through the second hydrogen filling pipeline 2022 and the second discharge pipeline 4021, the volume chamber flow detection module detects the hydrogen flow rate in the volume chamber 2021 in real time. In this embodiment, when the released hydrogen gas is discharged outward through the second hydrogen filling pipeline 2022 and the second discharge pipeline 4021, the volume chamber flow detection module sends the detected hydrogen flow rate to the processor 7 after detection. The processor 7 then performs a process comparing the hydrogen flow rate with the pre-stored maximum range of the second flow detection element 4013 (in this embodiment, the maximum range of the second flow detection element 4013 can be pre-input into the processor 7 by the operator through the operation input element 8). In contrast, if the hydrogen flow rate is greater than the maximum range of the second flow detection element 4013 (i.e., the real-time hydrogen release flow rate is greater than the maximum range of the second flow detection element 4013), then the fourth switch valve 2024 and the sixth switch valve 4022 are opened; if the hydrogen flow rate is less than or equal to the maximum range of the second flow detection element 4013, then the fourth switch valve 2024 and the sixth switch valve 4022 are closed, and the fifth switch valve 4012 is opened, the first discharge pipeline 4011 is connected, and the hydrogen released by the hydrogen storage device 5 enters the first discharge pipeline 4011 after passing through part of the first hydrogen charging pipeline 2012, and then is discharged outward from the end of the first discharge pipeline 4011 away from the first hydrogen charging pipeline 2012.

[0078] Furthermore, when hydrogen is discharged through the first venting pipe 4011, the second flow detection element 4013 detects the flow rate of hydrogen in the first venting pipe 4011 in real time and sends the detection value to the processor 7. In this embodiment, after the hydrogen inside the hydrogen storage device 5 is vented, there is no more hydrogen flowing in the first venting pipe 4011, so the detection result of the second flow detection element 4013 is 0. After receiving the detection result of 0 sent by the second flow detection element 4013, the processor 7 can determine that the hydrogen storage device 5 has been vented.

[0079] Step S107: Obtain the total mass of hydrogen released from hydrogen storage device 5.

[0080] Specifically, during the execution of step S602, the processor 7 calculates the first hydrogen release mass of the hydrogen storage device 5 (i.e., the mass of hydrogen discharged to the outside through the second discharge pipe 4021) based on the following formula: (7) in, The mass of the first hydrogen release is expressed in kg. This refers to the real-time hydrogen flow rate detected by the volumetric chamber flow detection module in hydrogen release mode, expressed in m³ / s. 3 / s.

[0082] During step S604, the processor 7 calculates the second hydrogen release mass of the hydrogen storage device 5 (i.e., the mass of hydrogen discharged through the first discharge pipe 4011) based on the following formula: (8) in, The second hydrogen release mass is expressed in kg. The flow rate of hydrogen detected by the second flow sensor 4013, in meters per second (m³). 3 / s.

[0084] M2= + (9) Where M2 is the total mass of hydrogen released, in kg.

[0085] Step S108: Determine whether the total mass of hydrogen released has reached the rated hydrogen release mass of hydrogen storage device 5; Step S109: Determine whether the total hydrogen charging mass has reached the rated hydrogen charging mass of the hydrogen storage device 5; Step S110: When the total hydrogen release mass reaches the rated hydrogen release mass and the total hydrogen charge mass reaches the rated hydrogen charge mass of the hydrogen storage device 5, the activation of the hydrogen storage device 5 is determined to be complete.

[0086] Specifically, after calculating M1, the processor 7 compares it with the rated hydrogen charging mass pre-stored in the processor 7 (in this embodiment, the rated hydrogen charging mass can be pre-input into the processor 7 by the operator through the operation input device 8). After calculating M2, it compares it with the rated hydrogen discharging mass pre-stored in the processor 7 (in this embodiment, the rated hydrogen discharging mass can be pre-input into the processor 7 by the operator through the operation input device 8). If M1 is greater than or equal to the rated hydrogen charging mass and M2 is greater than or equal to the rated hydrogen discharging mass, it indicates that the hydrogen storage device 5 has been activated.

[0087] In one embodiment of this application, the hydrogen storage system further includes a vacuum module 6 disposed on the hydrogen charging pipeline module 2, and the activation control method further includes the following steps: Step S1021: After the first venting operation is completed, control the vacuum module 6 to perform the first vacuuming operation to extract the residual hydrogen in the hydrogen charging pipeline module 2.

[0088] Specifically, the vacuum module 6 includes a suction pipe 601, a seventh switching valve 602, and a suction component 603. The suction pipe 601 is connected to the first hydrogen charging pipe 2012, and the connection point between the suction pipe 601 and the first hydrogen charging pipe 2012 is located between the hydrogen storage device 5 and the second switching valve 2014. The seventh switching valve 602 is installed on the suction pipe 601 and is used to open or close the suction pipe 601. The suction component 603 is installed on the suction pipe 601 and is used to extract residual hydrogen from the first hydrogen charging pipe 2012 and the second hydrogen charging pipe 2022.

[0089] Furthermore, in this embodiment, the end of the suction line 601 away from the first hydrogen charging line 2012 is connected to the outside or the waste gas collection tank, the seventh switch valve 602 can be selected as a solenoid valve and communicates with the processor 7, and the suction component 603 can be selected as a vacuum pump and communicates with the processor 7. In step S1021, the processor 7 first controls the first switching valve 2013, the third switching valve 2023, the fifth switching valve 4012, and the sixth switching valve 4022 to close, and controls the second switching valve 2014, the fourth switching valve 2024, the seventh switching valve 602, and the eighth switching valve 2015 to open. This connects part of the first hydrogen charging pipeline 2012 and part of the second hydrogen charging pipeline 2022 to the outside (or the waste gas collection tank). Then, the processor 7 controls the suction component 603 to activate the vacuum function to extract the residual hydrogen inside the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202. This prevents the residual hydrogen inside the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202 from mixing with air and causing a hazard when hydrogen is subsequently charged into the hydrogen storage device 5.

[0090] In one embodiment of this application, the hydrogen storage system further includes a vacuum module 6 disposed on the hydrogen charging pipeline module 2, and the activation control method further includes the following steps: Step S1051: After the second venting operation is completed, control the vacuum module 6 to perform the second vacuuming operation to extract the residual hydrogen in the hydrogen charging pipeline module 2 again.

[0091] Specifically, in step S1051, the processor 7 first controls the first switching valve 2013, the third switching valve 2023, the fifth switching valve 4012, and the sixth switching valve 4022 to close, and controls the second switching valve 2014, the fourth switching valve 2024, the seventh switching valve 602, and the eighth switching valve 2015 to open, so that part of the first hydrogen charging pipeline 2012 and part of the second hydrogen charging pipeline 2022 can be connected to the outside (or the waste gas collection tank). Then, the processor 7 controls the suction component 603 to start the vacuum function to extract the residual hydrogen inside the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202, so as to prevent the residual hydrogen inside the first hydrogen charging pipeline unit 201 and the second hydrogen charging pipeline unit 202 from mixing with air and causing danger when hydrogen is subsequently charged into the hydrogen storage device 5.

[0092] In one embodiment of this application, the hydrogen storage system further includes a vacuum module 6 disposed on the hydrogen charging pipeline module 2, and the activation control method further includes the following steps: Step S111: If the total hydrogen release mass does not reach the rated hydrogen release mass and / or the total hydrogen charge mass does not reach the rated hydrogen charge mass, it is determined that the activation of the hydrogen storage device 5 is not complete; Step S112: Control the vacuum module 6 to perform the third vacuum operation so that the surface oxide layer of the hydrogen storage powder inside the hydrogen storage device 5 is broken. Step S113: After the third vacuuming operation is completed, control the hydrogen storage system to repeat the activation operation until the hydrogen storage device 5 is activated.

[0093] Specifically, after step S108 is completed, if it is determined that M2 is less than the rated hydrogen release mass, and / or after step S109 is completed, if it is determined that M1 is less than the rated hydrogen charging mass, it indicates that the amount of hydrogen released by the hydrogen storage device 5 during the hydrogen release stage and / or the amount of hydrogen charged into the hydrogen storage device 5 during the hydrogen charging stage cannot meet the activation completion standard. At this time, the hydrogen storage device 5 needs to be reactivated. Before the reactivation operation, step S114 is executed first to break the surface oxide layer of the hydrogen storage powder made of alloy material inside the hydrogen storage device 5, laying the foundation for the subsequent reactivation operation. In step S114, the processor 7 controls the first switch valve 2013, the third switch valve 2023, the fifth switch valve 4012, and the sixth switch valve 4022 to close, and controls the second switch valve 2014, the fourth switch valve 2024, the seventh switch valve 602, and the eighth switch valve 602 to close. After 603 is opened, for The duration of 603 activation is accumulated, when After the cumulative duration of 603 is reached, the control will activate. 603. The vacuum function is turned off to ensure that the surface oxide layer of the hydrogen storage powder made of alloy material inside the hydrogen storage device 5 can be fully broken. Further, in this embodiment, steps S102-S109 are the activation operation of the hydrogen storage system. Repeated execution of steps S102-S109 can improve the hydrogen charging and discharging performance of the hydrogen storage device 5 until the activation of the hydrogen storage device 5 is completed.

[0094] The above-mentioned settings make the activation control method in this embodiment simple and easy to implement. It can automatically control the temperature and depressurize during the activation of the hydrogen storage device 5, and can also automatically determine whether the activation is complete. It is convenient to operate, safer, and reduces labor costs. It can accurately determine the decline in the hydrogen storage performance of the hydrogen storage device 5, improve the efficiency and accuracy of the activation of the hydrogen storage device 5, and accurately grasp the timing of reactivating the hydrogen storage device 5.

[0095] In one embodiment of this application, the hydrogen storage system further includes a temperature regulation module 3, and the activation control method further includes: Step S114: The refrigeration pipeline unit 303 of the temperature regulation module 3 is controlled to perform a refrigeration operation to adjust the internal temperature of the hydrogen storage device 5 to the preset hydrogen charging temperature.

[0096] Specifically, in this embodiment, steps S114 and S102 are executed simultaneously. The temperature regulation module 3 includes a conductive element 301, a heating pipeline unit 302, a cooling pipeline unit 303, and a second temperature detection element 501. The conductive element 301 is used to conduct heat or cold to the hydrogen storage device 5. The heating pipeline unit 302 is used to heat the conductive element 301, and the cooling pipeline unit 303 is used to cool the conductive element 301. The second temperature detection element 501 is disposed on the hydrogen storage device 5 and is used to detect the internal temperature of the hydrogen storage device 5. Further, the hydrogen storage device 5 is disposed inside the conductive element 301. The second temperature detection element 501 can be selected as a temperature sensor. The heating pipeline unit 302, the cooling pipeline unit 303, and the second temperature detection element 501 are all communicatively connected to the processor 7. After entering the hydrogen charging mode, the processor 7 controls the cooling pipeline unit 303 of the temperature regulation module 3 to perform a cooling operation on the hydrogen storage device 5. During the cooling operation of the cooling pipeline unit 303, the second temperature detection element 501 detects the internal temperature of the hydrogen storage device 5 in real time and sends the temperature to the processor 7. After receiving the real-time temperature, the processor 7 compares it with the preset hydrogen charging temperature stored in the processor 7 (in this embodiment, the preset hydrogen charging temperature can be pre-input into the processor 7 by the operator through the operation input element 8). If the temperature detected by the second temperature detection element 501 in real time does not reach the preset hydrogen charging temperature, the cooling pipeline unit 303 continues to perform a cooling operation on the hydrogen storage device 5; if the temperature detected by the second temperature detection element 501 in real time reaches the preset hydrogen charging temperature, the cooling pipeline unit 303 stops performing a cooling operation.

[0097] Furthermore, a medium receiving cavity is formed between the conductive member 301 and the hydrogen storage device 5. The conductive member 301 also has a first connecting port and a second connecting port that communicate with the medium receiving cavity. The refrigeration pipeline unit 303 includes a first circulation pipeline 3031, a cold medium tank 3032, a ninth switching valve 3033, a tenth switching valve 3034, and a first pumping member 3035. The two ends of the first circulation pipeline 3031 are respectively connected to the first connecting port and the second connecting port. The cold medium tank 3032 is disposed on the first circulation pipeline 3031 and is used to provide a cold medium (such as cold water). The ninth switching valve 3033 is disposed on the first circulation pipeline 3031 and is located on one side of the cold medium tank 3032. The tenth switching valve 3034 is disposed on the first circulation pipeline 3031 and is located on the side of the cold medium tank 3032 away from the fifth switching valve 4012. The first pumping member 3035 is disposed on the first circulation pipeline 3031 and is used to pump the liquid flowing out of the medium receiving cavity.

[0098] Furthermore, in this embodiment, the conductive element 301 can be a water bath heat exchange device, the ninth switching valve 3033 and the tenth switching valve 3034 can be solenoid valves, the first pumping element 3035 can be a water pump, and the ninth switching valve 3033, the tenth switching valve 3034 and the first pumping element 3035 are all communicatively connected to the processor 7.

[0099] In step S114, the processor 7 controls the ninth switch valve 3033 and the tenth switch valve 3034 to open, and controls the first pumping component 3035 to start the pumping function. After the cold medium in the cold medium tank 3032 flows out, it is transported through part of the first circulation pipeline 3031 and enters the medium receiving cavity through the first connecting port. The cold medium entering the medium receiving cavity absorbs the heat emitted by the hydrogen storage device 5 (the heat of the hydrogen storage device 5 is absorbed by the cold medium and then cooled down) and flows out of the medium receiving cavity through the second connecting port. The liquid flowing out of the medium receiving cavity (the liquid at this time is formed after the cold medium absorbs heat) returns to the cold medium tank 3032 under the pumping action of the first pumping component 3035. The above process continues, and the cold medium circulates in the flow channel formed by the first circulation pipeline 3031 and the medium receiving cavity and cools the hydrogen storage device 5.

[0100] Step S115: After the hydrogen charging operation is completed, the cooling pipeline unit 303 of the temperature regulation module 3 is in the off state.

[0101] Specifically, since the ninth switch valve 3033 and the tenth switch valve 3034 are in the open state when the hydrogen storage device 5 is cooled, and the first pumping component 3035 starts pumping, in step S115, the processor 7 controls the ninth switch valve 3033 and the tenth switch valve 3034 to close, and controls the first pumping component 3035 to turn off the pumping function, so as to stop cooling the hydrogen storage device 5.

[0102] In one embodiment of this application, such as Figure 3 As shown, the hydrogen storage system also includes a temperature regulation module 3, and the activation control method further includes the following steps: Step S116: After the hydrogen charging operation is completed, the temperature regulation module 3 is controlled to perform a heat exchange operation to cool down the cold medium circulating in the temperature regulation module 3 while heating up the first hot medium, wherein the first hot medium becomes the second hot medium after being heated.

[0103] In one embodiment of this application, the temperature regulation module 3 further includes a refrigeration internal circulation pipeline unit 304, an internal heating pipeline unit 305, and a heat exchange circulation pipeline unit 306. The heating pipeline unit 302 has a first heat medium tank 3022, and the internal heating pipeline unit 305 has a second heat medium tank 3055. Step S116, controlling the temperature regulation module 3 to perform the heat exchange operation, further includes steps S1161-S1164, wherein: Step S1161: Control the refrigeration internal circulation pipeline unit 304 to perform the cold medium circulation flow process of heat exchange operation, so that the cold medium inside the refrigeration internal circulation pipeline unit 304 is cooled down after passing through the heat absorption element 3063 of the heat exchange circulation pipeline unit 306. Step S1162: Control the heat exchange circulation pipeline unit 306 to perform the heat exchange operation, so that the heat absorption element 3063 of the heat exchange circulation pipeline unit 306 absorbs the heat of the cold medium and the heat dissipation element 3064 of the heat exchange circulation pipeline unit 306 dissipates the heat to the outside. Step S1163: Control the internal heating pipeline unit 305 to perform the first heat medium flow process of heat exchange operation, so that the first heat medium flowing out of the first heat medium tank 3022 absorbs heat and rises in temperature after passing through the heat sink 3064 and becomes the second heat medium flowing into the second heat medium tank 3055.

[0104] Specifically, the processor 7 is communicatively connected to the cooling pipeline unit 303, the cooling internal circulation pipeline unit 304, the internal heating pipeline unit 305, the heat exchange circulation pipeline unit 306, the second heat medium pipeline unit 307, and the heating pipeline unit 302. In this embodiment, the cooling pipeline unit 303, the cooling internal circulation pipeline unit 304, the internal heating pipeline unit 305, the heat exchange circulation pipeline unit 306, the second heat medium pipeline unit 307, and the heating pipeline unit 302 together constitute the temperature regulation module 3. The internal cooling circulation pipeline unit 304 is connected to the cold medium tank 3032 and passes through the heat absorption component 3063 to cool the cold medium in the cold medium tank 3032. The internal heating pipeline unit 305 is connected to the first heat medium tank 3022 of the heating pipeline unit 302 and passes through the heat dissipation component 3064. The internal heating pipeline unit 305 can use the heat dissipation component 3064 to convert the first heat medium in the first heat medium tank 3022 into the second heat medium flowing into the second heat medium tank 3055.

[0105] After the refrigeration piping unit 303 stops working, the processor 7 controls the heat exchange circulation piping unit 306 and the refrigeration internal circulation piping unit 304 to start working. The heat exchange circulation piping unit 306 has a circulating heat exchange medium inside, and the cold medium in the cold medium tank 3032 circulates in the refrigeration internal circulation piping unit 304. When the heat exchange medium and the cold medium in the cold medium tank 3032 flow through the heat absorber 3063, heat transfer occurs. The heat of the cold medium in the cold medium tank 3032 is absorbed by the heat exchange medium. Therefore, the cold medium flowing out of the heat absorber 3063 is cooled down and then flows back into the cold medium tank 3032. The temperature of the heat exchange medium flowing out of the heat absorber 3063 increases. The cold medium circulates in the refrigeration internal circulation piping unit 304, and the temperature of the cold medium in the cold medium tank 3032 continuously decreases. While the above process is going on, the first hot medium in the first hot medium tank 3022 flows out and absorbs the heat of the heat exchange medium when it passes through the heat sink 3064. After absorbing the above heat, the first hot medium becomes the second hot medium.

[0106] The heat exchange circulation pipeline unit 306 includes a heat exchange circulation pipeline 3061, a compressor 3062, a heat absorber 3063, a heat dissipation component 3064, a thirteenth switching valve 3065, and a fourteenth switching valve 3066. The heat exchange circulation pipeline 3061 contains a heat exchange medium. The compressor 3062 drives the heat exchange medium to flow within the heat exchange circulation pipeline 3061. The heat absorber 3063 is mounted on the heat exchange circulation pipeline 3061 and is used to regulate the flow of the refrigeration circulation pipeline 3041. The heat from the cold medium in the block flows to the heat exchange medium. The heat sink 3064 is installed on the heat exchange circulation pipe 3061 and is used to allow the heat from the heat exchange medium to flow to the first heat medium in the internal heating pipe unit 305. The thirteenth switch valve 3065 is installed on the heat exchange circulation pipe 3061 and is located between the compressor 3062 and the heat absorber 3063. The fourteenth switch valve 3066 is installed on the heat exchange circulation pipe 3061 and is located between the compressor 3062 and the heat sink 3064.

[0107] Furthermore, in this embodiment, the heat exchange medium can be selected as cooling water, the heat absorber 3063 and the heat dissipation component 3064 can both be selected as heat exchangers, and the thirteenth switching valve 3065 and the fourteenth switching valve 3066 can both be selected as solenoid valves. The compressor 3062, the heat absorber 3063, the heat dissipation component 3064, the thirteenth switching valve 3065, and the fourteenth switching valve 3066 are all communicatively connected to the processor 7. In step S1162, by controlling the compressor 3062, the heat absorber 3063, the heat dissipation component 3064, the thirteenth switching valve 3065, and the fourteenth switching valve 3066 to all open, the heat exchange medium can be circulated in the heat exchange circulation pipeline 3061. This allows the heat exchange medium to absorb heat from the cold medium when passing through the heat absorber 3063 and conduct heat to the first hot medium when passing through the heat dissipation component 3064. This enables the utilization of waste heat during the cooling process of the cold medium, reduces energy waste, and helps to shorten the heating time of the hydrogen storage device 5.

[0108] Furthermore, the heat exchange circulation pipeline unit 306 also includes an expansion valve 3067 disposed on the heat exchange circulation pipeline 3061 and located between the fourteenth switching valve 3066 and the heat sink 3064.

[0109] The refrigeration internal circulation piping unit 304 includes a refrigeration circulation piping 3041, a second pumping component 3042, a fifteenth switching valve 3043, and a sixteenth switching valve 3044. The two ends of the refrigeration circulation piping 3041 are respectively connected to the two connection ends of the cold medium tank 3032. The second pumping component 3042 is disposed on the refrigeration circulation piping 3041 and located between the cold medium tank 3032 and the heat absorption component 3063. The fifteenth switching valve 3043 is disposed on the refrigeration circulation piping 3041 and located between the cold medium tank 3032 and the second pumping component 3042. The sixteenth switching valve 3044 is disposed on the refrigeration circulation piping 3041 and located between the cold medium tank 3032 and the heat absorption component 3063.

[0110] Furthermore, the cold medium tank 3032 is connected to the first circulation pipeline 3031 through two additional connection terminals (i.e., the cold medium tank 3032 has four connection terminals in this embodiment). In this embodiment, the second pumping component 3042 can be a water pump, and the fifteenth switching valve 3043 and the sixteenth switching valve 3044 can both be solenoid valves. The second pumping component 3042, the fifteenth switching valve 3043, and the sixteenth switching valve 3044 are all communicatively connected to the processor 7. In step S1161, the processor 7 controls the fifteenth switching valve 3043 and the sixteenth switching valve 3044 to open, and controls the second pumping component 3042 to perform the pumping function, thereby realizing the circulation of the cold medium in the refrigeration circulation pipeline 3041 and cooling during the circulation process.

[0111] The internal heating pipeline unit 305 includes an internal heating pipeline 3051, a third pumping component 3052, a seventeenth switching valve 3053, and an eighteenth switching valve 3054. One end of the internal heating pipeline 3051 is connected to the first heat medium tank 3022, and the other end of the internal heating pipeline 3051 passes through the heat sink 3064 and is connected to the second heat medium tank 3055. The third pumping component 3052 is disposed on the internal heating pipeline 3051 and is located between the heat sink 3064 and the first heat medium tank 3022. The seventeenth switching valve 3053 is disposed on the internal heating pipeline 3051 and is located between the first heat medium tank 3022 and the third pumping component 3052. The eighteenth switching valve 3054 is disposed on the internal heating pipeline 3051 and is located between the second heat medium tank 3055 and the heat sink 3064.

[0112] Furthermore, in this embodiment, the third pumping component 3052 can be selected as a water pump, and the seventeenth switching valve 3053 and the eighteenth switching valve 3054 can both be selected as solenoid valves. The third pumping component 3052, the seventeenth switching valve 3053, and the eighteenth switching valve 3054 are all communicatively connected to the processor 7. In step S1163, the processor 7 controls the seventeenth switching valve 3053 and the eighteenth switching valve 3054 to open, and controls the third pumping component 3052 to perform the pumping function. This enables the first heat medium to absorb the heat dissipated by the heat exchange medium and be heated into the second heat medium after flowing out of the first heat medium tank 3022. The second heat medium then flows into the second heat medium tank 3055.

[0113] Furthermore, the hydrogen storage system also includes a third temperature detection element 9, a fourth temperature detection element 10, and a fifth temperature detection element 11, which are communicatively connected to the processor 7. The third temperature detection element 9 is disposed in the cold medium tank 3032 and is used to detect the temperature of the cold medium in the cold medium tank 3032; the fourth temperature detection element 10 is disposed in the first hot medium tank 3022 and is used to detect the temperature of the first hot medium in the first hot medium tank 3022; and the fifth temperature detection element 11 is disposed in the second hot medium tank 3055 and is used to detect the temperature of the second hot medium in the second hot medium tank 3055.

[0114] Step S1164: After confirming that the heat exchange operation is complete, control the internal heating pipeline unit 305 to be in the off state.

[0115] Specifically, the processor 7 has a preset cooling temperature (in this embodiment, the preset cooling temperature can be pre-input into the processor 7 by the operator through the operation input device 8). In step S1164, the third temperature detection device 9 detects the temperature of the cold medium in the cold medium tank 3032 in real time and sends the detection result to the processor 7. The processor 7 compares the received temperature with the preset cooling temperature. If the temperature detected by the third temperature detection device 9 reaches the preset cooling temperature, the heat exchange operation is determined to be completed. The processor 7 controls the compressor 3062, heat absorption device 3063, heat dissipation device 3064, thirteenth switch valve 3065, fourteenth switch valve 3066, fifteenth switch valve 3043, sixteenth switch valve 3044, second pumping device 3042, seventeenth switch valve 3053, eighteenth switch valve 3054 and third pumping device 3052 to stop in order to avoid wasting energy.

[0116] Step S117: After the heat exchange operation is completed and before the hydrogen release operation is performed, the second heat medium outflow pipeline unit 307 and the heating pipeline unit 302 of the control temperature regulation module 3 jointly perform the hydrogen release temperature regulation operation so that the second heat medium delivered by the first heat medium and the second heat medium outflow pipeline unit 307 jointly regulate the temperature inside the hydrogen storage device 5 to the preset hydrogen release temperature, wherein the first heat medium flows out from the heating pipeline unit 302.

[0117] In one embodiment of this application, the temperature regulation module 3 further includes a conductive member 301 for accommodating the hydrogen storage device 5, and a medium accommodating cavity is formed between the conductive member 301 and the hydrogen storage device 5. Step S117, which controls the second hot medium outflow pipeline unit 307 and the heating pipeline unit 302 of the temperature regulation module 3 to jointly perform the hydrogen release temperature regulation operation, further includes steps S1171-S1172, wherein: Step S171: Control the second heat medium pipeline unit 307 to perform the second heat medium delivery process of hydrogen release temperature regulation operation, so as to deliver the second heat medium to the heating pipeline unit 302; Step S1172: Control the heating pipeline unit 302 to perform the hot medium circulation flow process of hydrogen release temperature adjustment operation, so that the heating pipeline unit 302 transports the mixed hot medium formed by mixing the first hot medium and the second hot medium to the medium receiving cavity, and transports the medium receiving cavity flowing out of the medium receiving cavity to the first hot medium tank 3022 of the heating pipeline unit 302. The mixed hot medium raises the temperature inside the hydrogen storage device 5 to the preset hydrogen release temperature after flowing into the medium receiving cavity.

[0118] Specifically, the two ends of the second heat medium pipeline unit 307 are respectively connected to the second heat medium tank 3055 and the first circulation pipeline 3031. The connection position between the second heat medium pipeline unit 307 and the refrigeration pipeline unit 303 is located between the first connection port and the first end of the second circulation pipeline 3021. The second heat medium pipeline unit 307 includes a second heat medium pipeline 3071 and a nineteenth switching valve 3072. The two ends of the second heat medium pipeline 3071 are respectively connected to the second heat medium tank 3055 and the first circulation pipeline 3031. The nineteenth switching valve 3072 is installed on the second heat medium pipeline 3071 and is communicatively connected to the processor 7. In step S1171, the processor 7 controls the nineteenth switching valve 3072 to open, so that the second heat medium in the second heat medium tank 3055 can flow out through the second heat medium pipeline 3071.

[0119] The heating pipeline unit 302 includes a second circulation pipeline 3021, a first heat medium tank 3022, an eleventh switching valve 3023, and a twelfth switching valve 3024. Both ends of the second circulation pipeline 3021 are connected to the first circulation pipeline 3031. The connection point between the first end of the second circulation pipeline 3021 and the first circulation pipeline 3031 is located between the ninth switching valve 3033 and the conductive element 301. The connection point between the second end of the second circulation pipeline 3021 and the first circulation pipeline 3031 is located between the tenth switching valve 3034 and the first pumping element 3035. The first heat medium tank 3022 is disposed on the second circulation pipeline 3021. The eleventh switching valve 3023 is disposed on the second circulation pipeline 3021 and located on one side of the first heat medium tank 3022. The twelfth switching valve 3024 is disposed on the second circulation pipeline 3021 and located on the side of the first heat medium tank 3022 away from the seventh switching valve 602.

[0120] Furthermore, in this embodiment, the eleventh switching valve 3023 and the twelfth switching valve 3024 can be selected as solenoid valves. In step S1172, the processor 7 controls the eleventh switching valve 3023 and the twelfth switching valve 3024 to open, and controls the first pumping component 3035 to start the pumping function. After the first hot medium in the first hot medium tank 3022 flows out, it flows into a portion of the first circulation pipe 3031 through a portion of the second circulation pipe 3021 and mixes with the second hot medium flowing out of the second hot medium pipe 3071. The mixed hot medium formed by the two enters the medium receiving cavity through the first connecting port and is absorbed by the hydrogen storage device 5. After the hydrogen storage device 5 absorbs heat, its internal temperature can rise to the preset hydrogen release temperature. The above setting reuses the heat generated by the cooling of the cold medium. The hydrogen storage device 5 is heated by the second hot medium in the second hot medium tank 3055 and the first hot medium in the first hot medium tank 3022, which improves the heating efficiency of the hydrogen storage device 5 and shortens the heating time of the hydrogen storage device 5, which is conducive to improving the user experience of the hydrogen storage system.

[0121] The hydrogen storage device 5 is equipped with a second temperature detection element 501 for real-time detection of the internal temperature of the hydrogen storage device 5 and is connected to the processor 7. During the execution of step S1172, the second temperature detection element 501 detects the internal temperature of the hydrogen storage device 5 in real time and sends the temperature to the processor 7. After receiving the real-time temperature, the processor 7 compares it with the preset hydrogen release temperature stored in the processor 7 (in this embodiment, the preset hydrogen release temperature can be pre-input into the processor 7 by the operator through the operation input element 8). If the temperature detected by the second temperature detection element 501 in real time does not reach the preset hydrogen release temperature, step S1172 continues to be executed; if the temperature detected by the second temperature detection element 501 in real time reaches the preset hydrogen release temperature, step S1172 stops.
