Description

Technical Field

[0001] This invention relates to the field of digital management technology for hydrogen energy, and in particular to a hydrogen energy management system and its control method. Background Technology

[0002] As an energy form, the acquisition, storage, and management of hydrogen have always been challenges in this field, leading to the development of intelligent hydrogen energy production and operation end-to-end management platforms. For example, the lack of data exchange between hydrogen production / filling devices, hydrogen storage devices, and hydrogen consumption devices makes it impossible to accurately display the hydrogen content stored in the storage device. Users also need to know the time required to fill the storage device, the amount of hydrogen required, the duration the consumption device can sustain operation, and the remaining hydrogen content in the storage device after use.

[0003] Furthermore, hydrogen storage devices used for extended periods are prone to wear and tear or accidental gas release, leading to discrepancies between the actual hydrogen content stored and the information recorded in the read / write memory. This negatively impacts both the hydrogen filling and utilization processes. Therefore, a novel hydrogen energy management system and control method are needed to achieve visualized real-time monitoring and precise control of all stages of hydrogen production, filling, storage, and utilization. This system should also be capable of calibrating hydrogen storage devices, improving hydrogen energy management efficiency, and ultimately promoting cost reduction and efficiency improvement in the industry. Summary of the Invention

[0004] In order to overcome the above-mentioned technical defects, the purpose of this invention is to provide a hydrogen energy management system and its control method, which can accurately manage hydrogen energy devices in various stages such as hydrogen production, hydrogen filling, hydrogen storage and hydrogen use.

[0005] This invention discloses a control method for a hydrogen energy management system, wherein the management system includes a hydrogen storage device, a hydrogen production / filling device, a server, and a user terminal, and includes the following steps:

[0006] In response to a hydrogen charging command for the hydrogen production / charging device, the hydrogen production / charging device is controlled to enter a hydrogen charging mode, and the hydrogen production / charging device is controlled to charge the hydrogen storage device with hydrogen.

[0007] The initial hydrogen content of the hydrogen storage device is obtained by reading the readable / writable memory of the hydrogen storage device, and the initial hydrogen content is displayed on the first display module of the hydrogen production / filling device;

[0008] The hydrogen charging increment and charging time of the hydrogen storage device are acquired in real time. When the hydrogen charging increment of the hydrogen storage device is at a time interval of a hydrogen charging increment threshold, the current hydrogen content of the hydrogen storage device is acquired and written to the read / write memory. When the hydrogen charging time of the hydrogen storage device is at a time interval of a hydrogen charging time threshold, the read / write memory is read to obtain the current hydrogen content of the hydrogen storage device and displayed on the first display module.

[0009] When the hydrogen charging increment of the hydrogen storage device reaches the preset hydrogen charging threshold, the hydrogen production / charging device is controlled to stop charging hydrogen into the hydrogen storage device, the hydrogen charging count of the hydrogen storage device is incremented by one, the current hydrogen content and the number of hydrogen charging count of the hydrogen storage device are obtained and written to the readable / writable memory, the hydrogen charging increment, current hydrogen content, digital identity and the number of hydrogen charging count of the hydrogen storage device are fed back to the server, and the hydrogen production / charging device is controlled to exit the hydrogen charging mode.

[0010] Preferably, the method further includes the following steps:

[0011] In response to a calibration and charging command for the hydrogen production / charging device, the device is controlled to enter a calibration and charging mode, and the device is controlled to charge the hydrogen storage device with hydrogen.

[0012] The current hydrogen content of the hydrogen storage device is acquired in real time. When the current hydrogen content reaches the safe hydrogen content, the hydrogen production / filling device is controlled to continue filling the hydrogen storage device with hydrogen.

[0013] The detection gas pressure inside the hydrogen storage device is acquired in real time. When the detection gas pressure is greater than the calibration gas pressure threshold, the hydrogen production / filling device is controlled to stop filling the hydrogen storage device with hydrogen. The number of hydrogen fillings of the hydrogen storage device is increased by one, and the current hydrogen content of the hydrogen storage device is taken as the full content.

[0014] After obtaining the current hydrogen content and the number of times the hydrogen has been charged into the readable / writable memory, the digital identity of the hydrogen storage device and the current hydrogen content are fed back to the server, and the hydrogen production / charging device is controlled to exit the calibration and charging mode.

[0015] Preferably, the method further includes the following steps:

[0016] The server monitors the usage time of the hydrogen storage device in real time. Every time the usage time of the hydrogen storage device is at a calibration cycle, the server sends a calibration prompt signal to the user terminal. The calibration prompt signal includes the digital identity of the hydrogen storage device.

[0017] Preferably, the calibration cycle of the hydrogen storage device decreases as the number of hydrogen refills increases.

[0018] Preferably, the management system further includes a hydrogen-using device, and further includes the following steps:

[0019] In response to a start command for the hydrogen fuel cell stack in the hydrogen-using device, the hydrogen-using device is controlled to enter a hydrogen-using mode, causing the hydrogen-using device to consume the hydrogen stored in the hydrogen storage device.

[0020] The specified consumption amount of the hydrogen-using device in the current hydrogen-using cycle is obtained, and the detected consumption amount of the hydrogen storage device is obtained in real time. When the detected consumption amount reaches the specified consumption amount, the current hydrogen content of the hydrogen storage device is obtained and written to the readable / writable memory. Then, the current hydrogen content and digital identity of the hydrogen storage device are fed back to the second display module of the hydrogen-using device and the server, and the next hydrogen-using cycle is entered and this step is repeated.

[0021] In response to a shutdown command for the hydrogen fuel cell stack, the hydrogen-consuming device is controlled to stop consuming the hydrogen stored in the hydrogen storage device. After obtaining the current hydrogen content of the hydrogen storage device and writing it into the readable / writable memory, the current hydrogen content and digital identity of the hydrogen storage device are fed back to the second display module and the server, and the hydrogen-consuming device is controlled to exit the hydrogen-consuming mode.

[0022] Preferably, the step of obtaining the detection consumption of the hydrogen-using device in real time includes,

[0023] The detection consumption rate C of the hydrogen-using device in the current hydrogen-using cycle is obtained by calculating C = K * I * N, and the detection consumption amount of the hydrogen storage device is obtained by calculating the detection consumption rate C and the detection consumption time of the current hydrogen-using cycle.

[0024] Where K is the Faraday constant, I is the sum of the load current, heater current and static fixed current of the hydrogen-using device, and N is the number of cells in the hydrogen fuel cell stack.

[0025] Preferably, the method further includes the following steps:

[0026] When the operation of writing the current hydrogen content of the hydrogen storage device to the readable / write memory fails, the current hydrogen content and digital identity of the hydrogen storage device at the end of the previous hydrogen consumption cycle are fed back to the second display module and the server.

[0027] Preferably, the step of controlling the hydrogen-using device to enter hydrogen-using mode in response to a start command for the hydrogen fuel cell stack in the hydrogen-using device includes,

[0028] In response to a start command from the controller of the hydrogen fuel cell stack, the readable / writable memory of the hydrogen storage device is read to obtain the current hydrogen content and digital identity of the hydrogen storage device;

[0029] In response to a start command for the hydrogen fuel cell stack, the management system is controlled to enter a hydrogen consumption mode, causing the hydrogen consumption device to consume the hydrogen stored in the hydrogen storage device.

[0030] Preferably, the method further includes the following steps:

[0031] The server monitors the current hydrogen content of the hydrogen storage device in real time. When the current hydrogen content of the hydrogen storage device is lower than the hydrogen content threshold, the server sends a hydrogen charging prompt signal to the user terminal. The hydrogen charging prompt signal includes the current hydrogen content of the hydrogen storage device and a digital identity.

[0032] This invention also discloses a hydrogen energy management system, including a hydrogen storage device, a hydrogen production / filling device, a server, and a user terminal.

[0033] When the hydrogen production / charging device enters the hydrogen charging mode, the hydrogen production / charging device charges the hydrogen storage device with hydrogen gas;

[0034] The first read / write module in the hydrogen production / filling device reads the readable / writable memory of the hydrogen storage device to obtain the initial hydrogen content of the hydrogen storage device, and the first display module of the hydrogen production / filling device displays the initial hydrogen content;

[0035] When the hydrogen storage device increases its hydrogen supply increment every time it reaches a hydrogen supply increment threshold, the first read / write module writes the current hydrogen content of the hydrogen storage device into the readable / write memory. When the hydrogen storage device's hydrogen supply time reaches a hydrogen supply time threshold, the first read / write module reads the readable / write memory to obtain the current hydrogen content of the hydrogen storage device. The first display module displays the current hydrogen content.

[0036] When the hydrogen charging increment of the hydrogen storage device reaches the preset hydrogen charging threshold, the hydrogen production / charging device exits the hydrogen charging mode, stops charging hydrogen into the hydrogen storage device, and the hydrogen storage device's hydrogen charging count increases by one. The first read / write module writes the current hydrogen content and the hydrogen charging count of the hydrogen storage device into the read / write memory. The hydrogen production / charging device feeds back the hydrogen charging increment, current hydrogen content, digital identity, and hydrogen charging count of the hydrogen storage device to the server.

[0037] Compared with existing technologies, the above technical solution has the following advantages: it enables data connectivity and visual management of hydrogen energy devices in all aspects of hydrogen production, charging, storage and use; it calibrates hydrogen storage devices according to the frequency of calibration reminders based on the lifespan of the hydrogen storage device; it can accurately display the hydrogen content; and it improves the overall operating efficiency of hydrogen energy devices and the user experience.

[0050] like Figures 1 to 2 As shown, this invention discloses a control method for a hydrogen energy management system, wherein the management system includes a hydrogen storage device, a hydrogen production / filling device, a server, and a user terminal, and the control method includes the following steps:

[0051] S110, in response to a hydrogen charging command to the hydrogen production / charging device, controls the hydrogen production / charging device to enter the hydrogen charging mode, so that the hydrogen production / charging device charges the hydrogen storage device with hydrogen.

[0052] Specifically, by way of example and not limitation, a hydrogen storage device can be a hydrogen storage cylinder, a hydrogen fuel cell, a solid-state hydrogen battery, or other equipment used to store hydrogen; a hydrogen production / filling device can be an integrated hydrogen production / filling machine. When the hydrogen production / filling device is connected to the hydrogen storage device through a hydrogen filling pipeline, the hydrogen production / filling device can produce hydrogen and fill the hydrogen storage device with hydrogen.

[0053] It is understandable that the hydrogen charging command for the hydrogen production / charging device can be generated by the user directly operating the device after connecting the hydrogen storage device to it, or it can be generated by the user remotely operating the device through a server or user terminal. In response to this charging command, the hydrogen production / charging device is controlled to enter the charging mode. Specifically, the electrolysis unit of the device is controlled to produce hydrogen, and the charging valve of the charging pipeline connected to the device is opened, causing the device to begin producing hydrogen and charging it into the hydrogen storage device.

[0054] S120: Read the readable / writable memory of the hydrogen storage device to obtain the initial hydrogen content of the hydrogen storage device, and display the initial hydrogen content on the first display module of the hydrogen production / filling device.

[0055] Specifically, in practical applications, hydrogen storage devices can be multiple replaceable devices. Therefore, each hydrogen storage device is equipped with a read / write memory. The read / write memory is a storage device capable of recording relevant data about the hydrogen storage device. In this embodiment, each read / write memory contains the digital identity of the hydrogen storage device it belongs to, as well as information such as hydrogen content, number of times it has been refilled, usage time, and service life. Specifically, the digital identity includes a unique device number corresponding to the hydrogen storage device; the hydrogen content is the proportion of the volume of hydrogen stored in the device to its maximum capacity; the number of times it has been refilled is the number of times it has been refilled with hydrogen via a hydrogen production / refilling device; the usage time is the time since the device was manufactured; and the service life is the remaining safe operating time or remaining number of refills for the device.

[0056] By reading the readable / writable memory of the hydrogen storage device connected to the hydrogen production / charging device through a first read / write module installed on the hydrogen production / charging device, the digital identity and initial hydrogen content of the hydrogen storage device can be obtained. It is understood that the initial hydrogen content refers to the hydrogen content of the hydrogen storage device at the moment the management system enters the hydrogen charging mode. The initial hydrogen content of the hydrogen storage device is displayed on a first display module, which may be, for example, an external display screen installed on the hydrogen production / charging device.

[0057] S130. Real-time acquisition of hydrogen charging increment and hydrogen charging time of hydrogen storage device. When the hydrogen charging increment of hydrogen storage device is at a hydrogen charging increment threshold interval, the current hydrogen content of hydrogen storage device is acquired and written to readable / writable memory. When the hydrogen charging time of hydrogen storage device is at a hydrogen charging time threshold interval, the readable / writable memory is read to acquire the current hydrogen content of hydrogen storage device and displayed on the first display module of hydrogen production / charging device.

[0058] Specifically, the hydrogen filling increment refers to the proportion of the volume of hydrogen gas added to the hydrogen storage device by the hydrogen production / filling device to the maximum volume of the hydrogen storage device, and the hydrogen filling time refers to the duration for the hydrogen production / filling device to add hydrogen gas to the hydrogen storage device. In this embodiment, the hydrogen filling increment threshold and the hydrogen filling time threshold can be pre-stored in the hydrogen production / filling device, and the hydrogen filling increment is compared with the hydrogen filling increment threshold and the hydrogen filling time is compared with the hydrogen filling time threshold, respectively.

[0059] At each hydrogen increment threshold, the hydrogen production / filling device calculates the current hydrogen content of the storage device based on the initial hydrogen content and the hydrogen increment, and writes it to the readable / writable memory via the first read / write module, thus updating the hydrogen content written in the readable / writable memory. For example, assuming the hydrogen increment threshold is 2%, the hydrogen increment increases as the hydrogen production / filling device fills the storage device. At each 2% increment, the current hydrogen content of the storage device is obtained and written to the readable / writable memory; that is, the current hydrogen content written in the readable / writable memory is updated at each 2% increment.

[0060] At each hydrogen charging time threshold interval, the first read / write module reads the readable / writable memory and displays the current hydrogen content written in the readable / writable memory on the first display module. For example, assuming the hydrogen charging time threshold is 10 seconds, and the charging time increases as the hydrogen production / charging device charges the hydrogen storage device, the current hydrogen content written in the readable / writable memory is read and displayed on the first display module every 10 seconds. That is, the current hydrogen content displayed on the first display module is updated every 10 seconds.

[0061] Specifically, such as Figure 2 As shown, to update the current hydrogen content displayed on the first display module according to the hydrogen charging time threshold, a repeating timer can be set on the hydrogen production / charging device. The duration of each timer cycle is the hydrogen charging time threshold. After the hydrogen production / charging device enters the hydrogen charging mode, the timer starts counting down simultaneously as the device charges the hydrogen storage device. The hydrogen production / charging device detects trigger events, and each trigger event corresponds to... Figure 2 The process shown is used to implement the above control method. Each time the timer completes a count, the first read / write module reads the readable / writable memory and displays the current hydrogen content written in the readable / writable memory on the first display module. After each display update, the trigger event is cleared, and the timer restarts the count until the hydrogen increment reaches the preset threshold, at which point the hydrogen charging mode is exited.

[0062] Furthermore, as a supplement to step S130, to address the risk of potential malfunctions in the first read / write module, a read / write repetition threshold can be pre-stored in the hydrogen production / filling device. When an operation to write to or read from the readable / write memory fails, the operation is repeatedly triggered, and the repetition count is calculated. When the repetition count reaches the read / write repetition threshold, the hydrogen production / filling device stops supplying hydrogen to the hydrogen storage device and exits the hydrogen filling mode. This prevents the inability to accurately display the current hydrogen content of the hydrogen storage device in the event of a malfunction in the first read / write module, thus avoiding obstacles to the subsequent use of the hydrogen storage device.

[0063] S140 When the hydrogen charging increment of the hydrogen storage device reaches the preset hydrogen charging threshold, the control / charging device stops charging hydrogen into the hydrogen storage device, the number of hydrogen charging cycles of the hydrogen storage device increases by one, the current hydrogen content and the number of hydrogen charging cycles of the hydrogen storage device are obtained and written to the readable / writable memory, the hydrogen charging increment, current hydrogen content, digital identity and the number of hydrogen charging cycles of the hydrogen storage device are fed back to the server, and the control / charging device exits the hydrogen charging mode.

[0064] Specifically, the preset hydrogen charging threshold represents the proportion of hydrogen volume to be charged into the hydrogen storage device during the current hydrogen charging mode, relative to the maximum volume of the device. This threshold can be determined in the hydrogen charging command for the hydrogen production / charging device. For example, if the initial hydrogen content of the hydrogen storage device is 20%, and the hydrogen charging command for the hydrogen production / charging device indicates that the hydrogen storage device should be charged to 100% hydrogen content, the preset hydrogen charging threshold can be determined to be 80%. Therefore, when the hydrogen charging increment of the hydrogen storage device reaches 80%, the hydrogen production / charging device stops charging the hydrogen storage device, the number of hydrogen charges recorded in the read / write memory is incremented, the current hydrogen content of the hydrogen storage device is obtained as 100%, and the first read / write module writes the current hydrogen content of 100% and the updated number of hydrogen charges into the read / write memory. At this point, the control and management system exits the hydrogen charging mode. Furthermore, the hydrogen production / filling device feeds back the hydrogen filling increment, current hydrogen content, digital identity, and number of filling cycles of the hydrogen storage unit to the server. Since the digital identity corresponds one-to-one with each hydrogen storage unit, the server accurately records the current hydrogen content and number of filling cycles for each unit. Moreover, the server can send the recorded current hydrogen content and number of filling cycles of any hydrogen storage unit to the user terminal for display, allowing users to access the hydrogen storage status of each unit on their devices and achieving data interoperability.

[0065] In one alternative implementation, the following steps are also included:

[0066] In response to a calibration and charging command for the hydrogen production / charging device, the device is controlled to enter calibration and charging mode, allowing it to charge the hydrogen storage device with hydrogen.

[0067] The current hydrogen content of the hydrogen storage device is acquired in real time. When the current hydrogen content reaches the safe hydrogen content, the hydrogen production / charging device is controlled to continue to charge the hydrogen storage device with hydrogen.

[0068] The detection gas pressure inside the hydrogen storage device is acquired in real time. When the detection gas pressure is greater than the calibration gas pressure threshold, the hydrogen production / filling device stops filling the hydrogen storage device with hydrogen, and the number of hydrogen fillings of the hydrogen storage device is incremented by one. After writing the current hydrogen content of the hydrogen storage device as full content and the number of hydrogen fillings to the readable / writable memory, the digital identity of the hydrogen storage device, the current hydrogen content and the number of hydrogen fillings are fed back to the server, and the hydrogen production / filling device is controlled to exit the calibration hydrogen filling mode.

[0069] Specifically, during the use of hydrogen storage devices, unexpected gas release or read / write memory update failures may occur, leading to a discrepancy between the current hydrogen content written in the read / write memory and the actual hydrogen content stored in the device. Therefore, it is necessary to calibrate and refill the hydrogen storage device.

[0070] Normally, for safety reasons, the hydrogen filling command for the hydrogen production / filling device instructs the hydrogen storage device to fill with hydrogen to a hydrogen content of 95%, i.e., the safe hydrogen content is set at 95%. This means that when the current hydrogen content in the storage device reaches 95%, the hydrogen production / filling device stops filling the storage device, and the management system exits the hydrogen filling mode. However, in the calibration hydrogen filling mode of this invention, the detection pressure within the storage device is used as the criterion for stopping hydrogen filling. Even after the current hydrogen content reaches 95%, hydrogen filling continues until the detection pressure exceeds a preset calibration pressure threshold, ensuring that the actual hydrogen content stored in the storage device matches the current hydrogen content written in the read / write memory.

[0071] It is understandable that the calibration / charging command for the hydrogen production / charging device can be generated by the user directly operating the device after connecting the hydrogen storage device to it, or it can be generated by the user remotely operating the device through a server or user terminal. In response to this calibration / charging command, the hydrogen production / charging device is controlled to enter calibration / charging mode. Specifically, the electrolysis unit of the device is controlled to produce hydrogen, and the charging valve of the charging pipeline connected to the device is opened, causing the device to begin producing hydrogen and charging it into the hydrogen storage device.

[0072] Specifically, the detection pressure inside the hydrogen storage device is acquired in real time by a sensing unit within the device. When the detection pressure exceeds the calibration pressure threshold, the actual hydrogen content stored in the device is considered to be full, i.e., 100%. The hydrogen production / filling device is then controlled to stop filling the storage device with hydrogen. The number of hydrogen fills recorded in the read / write memory is incremented by one. The first read / write module writes 100% as the current hydrogen content into the read / write memory and also writes the updated number of hydrogen fills into the read / write memory. The device's digital identity, current hydrogen content, and number of hydrogen fills are then fed back to the server. At this point, the hydrogen production / filling device exits the calibration hydrogen filling mode.

[0073] Preferably, the method further includes the following steps:

[0074] The server monitors the usage time of the hydrogen storage device in real time. Every time the usage time of the hydrogen storage device is at a calibration cycle, the server sends a calibration prompt signal to the user terminal. The calibration prompt signal includes the digital identity of the hydrogen storage device.

[0075] Specifically, the server stores the usage duration of the hydrogen storage devices. For any given hydrogen storage device, at each calibration cycle, the server sends a calibration reminder signal to the user, indicating that the device should be charged with hydrogen in calibration charging mode. For example, for any given hydrogen storage device, every 3 months, the server sends a calibration reminder signal with the device's digital identity to the user.

[0076] Preferably, the calibration cycle of the hydrogen storage device decreases as the number of times it has been charged with hydrogen increases.

[0077] It is understandable that the longer a hydrogen storage device is used, the more likely it is to have a discrepancy between the current hydrogen content written in the readable / writable memory and the actual stored hydrogen content. Therefore, the calibration cycle of any hydrogen storage device is determined based on the number of times it has been filled with hydrogen, so that the more times the hydrogen storage device has been filled with hydrogen, the shorter its calibration cycle and the higher the frequency of sending calibration prompt signals to that hydrogen storage device.

[0078] In one alternative implementation, such as Figures 3 to 4 As shown, the management system also includes a hydrogen-using device, and the control method further includes the following steps:

[0079] S210, in response to the start command of the hydrogen fuel cell stack in the hydrogen-using device, controls the hydrogen-using device to enter the hydrogen-using mode and uses the hydrogen-using device to consume the hydrogen stored in the hydrogen storage device.

[0080] As an example, and not a limitation, hydrogen-using devices can include hydrogen fuel cell vehicles, hydrogen emergency power supplies, etc., which convert hydrogen into electricity by consuming hydrogen. It is understood that the start command for the hydrogen fuel cell stack can be generated by the user directly operating the hydrogen-using device, or it can be generated by the user remotely operating the hydrogen-using device through a server or user terminal. In response to this start command, the control and management system enters hydrogen-using mode, using the hydrogen device to consume the hydrogen stored in the hydrogen storage device.

[0081] S220. Obtain the specified consumption amount of the hydrogen-using device in the current hydrogen-using cycle, and obtain the detected consumption amount of the hydrogen storage device in real time. When the detected consumption amount reaches the specified consumption amount, obtain the current hydrogen content of the hydrogen storage device, write it into the readable / writable memory, and then feed back the current hydrogen content and digital identity of the hydrogen storage device to the second display module and server of the hydrogen-using device, and enter the next hydrogen-using cycle and repeat this step.

[0082] Specifically, the specified consumption amount required by the hydrogen-using device is determined for each hydrogen consumption cycle, that is, the volume of hydrogen required by the hydrogen-using device in the current hydrogen consumption cycle. The detected consumption amount of the hydrogen storage device is the volume of hydrogen reduced by the hydrogen storage device. Before the detected consumption amount reaches the specified consumption amount, the hydrogen-using device continues to consume hydrogen; when the detected consumption amount reaches the specified consumption amount, the second read / write module in the hydrogen-using device writes the updated current hydrogen content of the hydrogen storage device after the current hydrogen consumption cycle into the readable / writable memory, and feeds back the updated current hydrogen content of the hydrogen storage device and its digital identity to the second display module and server of the hydrogen-using device. The second display module can be an instrument on the hydrogen-using device; the process continues into the next hydrogen consumption cycle, that is, the specified consumption amount and the detected consumption amount for the next hydrogen consumption cycle are obtained, and when the detected consumption amount reaches the specified consumption amount again, the second read / write module updates the current hydrogen content and writes it into the readable / writable memory.

[0083] S230, in response to the shutdown command of the hydrogen fuel cell stack, the hydrogen device stops consuming the hydrogen stored in the hydrogen storage device, obtains the current hydrogen content of the hydrogen storage device and writes it into the readable / writable memory, then feeds back the current hydrogen content and digital identity of the hydrogen storage device to the second display module and the server, and controls the hydrogen device to exit the hydrogen consumption mode.

[0084] Specifically, in hydrogen-using mode, users can directly operate the hydrogen-using device to generate a shutdown command for the hydrogen fuel cell stack, or remotely operate the hydrogen-using device through a server or user terminal to generate a shutdown command for the hydrogen fuel cell stack. In response to this shutdown command, even if the detected consumption may not have reached the specified consumption level, the hydrogen-using device stops consuming the hydrogen stored in the hydrogen storage device. The second read / write module writes the updated current hydrogen content of the hydrogen storage device into the readable / writable memory and feeds back the updated current hydrogen content of the hydrogen storage device and its digital identity to the second display module of the hydrogen-using device and the server.

[0085] Preferably, the step of obtaining the detection consumption of hydrogen in real time includes,

[0086] The detection consumption rate C of the hydrogen-using device in the current hydrogen-using cycle is calculated according to C = K * I * N, and the detection consumption amount of the hydrogen storage device is calculated according to the detection consumption rate C and the detection consumption time of the current hydrogen-using cycle.

[0087] Where K is the Faraday constant, I is the sum of the load current, heater current and static fixed current of the hydrogen-using device, and N is the number of cells in the hydrogen fuel cell stack.

[0088] Specifically, the detection consumption rate C is measured in L / min. By multiplying the detection consumption rate by the detection consumption time of the current hydrogen consumption cycle, the amount of hydrogen consumed after different detection consumption times can be obtained in real time.

[0089] Preferably, such as Figure 4 As shown, it also includes the following steps:

[0090] When the operation of writing the current hydrogen content of the hydrogen storage device to the readable / write memory fails, the current hydrogen content and digital identity of the hydrogen storage device at the end of the previous hydrogen consumption cycle are fed back to the second display module and the server.

[0091] Understandably, when the second read / write module malfunctions and the operation of writing to the readable / write memory fails, the current hydrogen content and digital identity of the hydrogen storage device at the end of the previous hydrogen consumption cycle are fed back to the second display module and the server, waiting to be rewritten to the readable / write memory at the end of the next hydrogen consumption cycle.

[0092] Preferably, such as Figure 4 As shown, the steps for the control and management system to enter hydrogen consumption mode in response to a start command for the hydrogen fuel cell stack in a hydrogen-using device include:

[0093] In response to the start command from the controller of the hydrogen fuel cell stack, the readable / writable memory of the hydrogen storage device is read to obtain the current hydrogen content and digital identity of the hydrogen storage device;

[0094] In response to the start command of the hydrogen fuel cell stack, the control and management system enters the hydrogen consumption mode, using the hydrogen device to consume the hydrogen stored in the hydrogen storage device.

[0095] Specifically, after the controller of the hydrogen fuel cell stack is started, if no start command is generated for the hydrogen fuel cell stack, the control and management system will not enter the hydrogen consumption mode. Instead, the second read / write module will read the readable / writable memory to obtain the current hydrogen content and digital identity of the hydrogen storage device and display it to the user.

[0096] In one alternative implementation, the following steps are also included:

[0097] The server monitors the current hydrogen content of the hydrogen storage device in real time. When the current hydrogen content of the hydrogen storage device is lower than the hydrogen content threshold, the server sends a hydrogen charging prompt signal to the user. The hydrogen charging prompt signal includes the current hydrogen content of the hydrogen storage device and its digital identity.

[0098] Specifically, in hydrogen filling mode, the hydrogen production / filling device feeds back the current hydrogen content of the hydrogen storage device to the server, and in hydrogen use mode, the hydrogen use device feeds back the current hydrogen content of the hydrogen storage device to the server. This allows the server to monitor the current hydrogen content of any hydrogen storage device in real time. When the server detects that the current hydrogen content of any hydrogen storage device is below a threshold, it sends a hydrogen filling prompt signal to the server, indicating that the device should be filled. The hydrogen filling prompt signal includes the device's digital identifier for easy user identification.

[0099] like Figure 5 As shown, the present invention also discloses a hydrogen energy management system 1000, including a hydrogen storage device 1100, a hydrogen production / filling device 1200, a server 1300, and a user terminal 1400.

[0100] When the hydrogen production / charging device 1200 enters the hydrogen charging mode, the hydrogen production / charging device 1200 charges the hydrogen storage device 1100 with hydrogen gas;

[0101] The first read / write module in the hydrogen production / filling device 1200 reads the readable / writable memory of the hydrogen storage device 1100 to obtain the initial hydrogen content of the hydrogen storage device 1100, and the first display module of the hydrogen production / filling device 1200 displays the initial hydrogen content.

[0102] When the hydrogen filling increment of the hydrogen storage device 1100 is at each interval of the hydrogen filling increment threshold, the first read / write module writes the current hydrogen content of the hydrogen storage device 1100 into the readable / write memory. When the hydrogen filling time of the hydrogen storage device 1100 is at each interval of the hydrogen filling time threshold, the first read / write module reads the readable / write memory to obtain the current hydrogen content of the hydrogen storage device 1100. The first display module of the hydrogen production / filling device 1200 displays the current hydrogen content.

[0103] When the hydrogen filling increment of the hydrogen storage device 1100 reaches the preset hydrogen filling threshold, the hydrogen production / filling device 1200 exits the hydrogen filling mode, stops filling the hydrogen storage device 1100 with hydrogen, and the hydrogen filling count of the hydrogen storage device 1100 increases by one. The first read / write module writes the current hydrogen content and the number of hydrogen fillings of the hydrogen storage device 1100 into the read / write memory. The hydrogen production / filling device 1200 feeds back the hydrogen filling increment, current hydrogen content, digital identity, and number of hydrogen fillings of the hydrogen storage device 1100 to the server 1300.

[0104] Furthermore, the management system 1000 also includes a hydrogen-using device 1500. When the hydrogen-using device 1500 enters the hydrogen-using mode, it consumes the hydrogen stored in the hydrogen storage device 1100.

[0105] Compared with existing technologies, the above technical solution has the following advantages: it enables data connectivity and visualization management and calibration of hydrogen energy equipment in all aspects of hydrogen production, filling, storage and use, accurately displays hydrogen content, and improves the overall operating efficiency and user experience of hydrogen energy equipment.

[0106] It should be noted that the embodiments of the present invention have better implementability and are not intended to limit the present invention in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
