Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrogen storage modules, and in particular to an exchange type hydrogen storage module and a vehicle. BACKGROUND

[0002] In recent years, awareness of inhibiting the greenhouse effect of the earth has increased, and in particular, in order to reduce carbon dioxide emissions from vehicles, development of vehicles using hydrogen as fuel, such as fuel cell vehicles and hydrogen engine vehicles, has been widespread. Such vehicles are generally equipped with a hydrogen storage module filled with hydrogen as a hydrogen supply source. Currently, a filled type hydrogen storage module is commonly used, and when the hydrogen is insufficient, the vehicle is driven into a hydrogen filling station to fill the hydrogen. However, if a large commercial vehicle (such as a heavy truck) with a large hydrogen consumption amount uses a filled type hydrogen storage module, there is a problem that the time for refueling is too long, thereby affecting the commercial efficiency. Therefore, it is considered to use an exchange type hydrogen storage module to shorten the time for refueling.

[0003] Compared with the filled type hydrogen storage module, the exchange type hydrogen storage module has a more complex structure, and there is also a use scenario of exchanging by disassembling and assembling in use, thereby requiring more careful handling of safety hazards. SUMMARY

[0037] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0038] This application provides an exchangeable hydrogen storage module 1 for use in vehicles. The vehicle can be a heavy-duty truck or other large commercial vehicle; this application does not specifically limit its application to this type.

[0039] The aforementioned exchangeable hydrogen storage module 1 can be understood as a hydrogen storage module that can be exchanged as a whole to provide sufficient hydrogen as fuel for the vehicle in a timely manner. Using this exchangeable module achieves rapid hydrogen replenishment, effectively shortening the hydrogen replenishment time compared to a refillable hydrogen tank.

[0040] The hydrogen storage module 1 has both an installed state, mounted on a vehicle, and a detached state, removed from the vehicle. (Combined with...) Figure 1 and Figure 2 , Figure 1 The hydrogen storage module 1 shown is in the installation state. Figure 2 The hydrogen storage module 1 shown is in a disassembled state. In scenarios where the vehicle is driving normally and has sufficient hydrogen, requiring no replacement of the hydrogen storage module 1, the hydrogen storage module 1 is in an installed state. This installed state can be understood as the hydrogen storage module 1 being stably installed on the vehicle. In scenarios where the vehicle needs to replace the hydrogen storage module 1, such as when the hydrogen in the module needs to be replenished through exchange, or when the vehicle is at a hydrogen exchange station, the hydrogen storage module is in a disassembled state. This disassembled state can be understood as the hydrogen storage module 1 being removed from the vehicle to allow for the installation of a new hydrogen storage module 1. The vehicle may include a disassembly / removal assembly 2, which enables the installation and removal of the exchangeable hydrogen storage module 1.

[0041] Based on the above basic introduction of the exchange-type hydrogen storage module 1, combined with... Figure 3 and Figure 4 The exchangeable hydrogen storage module 1 specifically includes a hydrogen storage tank 101, a coupler 114, a sensor, and a control unit 103.

[0042] The hydrogen storage tank 101 is used to store hydrogen gas, specifically, high-pressure hydrogen gas. The hydrogen storage module 1 may include one or more hydrogen storage tanks 101. The hydrogen storage tank 101 has an opening, at which a valve 102 is provided. This valve 102 controls whether the hydrogen gas inside the hydrogen storage tank 101 is discharged to the outside. For example, when the valve 102 at the opening of the hydrogen storage tank 101 is open, the hydrogen gas inside the hydrogen storage tank 101 can be discharged from the hydrogen storage tank 101.

[0043] The valve 102 at the opening of the hydrogen storage tank 101 can be opened and closed as needed. When the valve 102 at the opening of the hydrogen storage tank 101 receives a relevant control signal or control command, for example, when it is necessary to provide fuel (hydrogen) to the vehicle's power system (not shown in the figure), the valve 102 at the opening of the hydrogen storage tank 101 can receive a control signal to open the valve 102 and open the valve 102 at the opening of the hydrogen storage tank 101, so that the hydrogen in the hydrogen storage tank 101 can be discharged from the hydrogen storage tank 101 and enter the fuel injection port of the power system to provide hydrogen to the power system. Here, the power system can be, but is not limited to, a fuel cell system.

[0044] Of course, when the power system does not require fuel supply, the valve 102 at the opening of the hydrogen storage tank 101 can be returned to the closed state to stop the hydrogen storage tank 101 from supplying hydrogen fuel to the power system. Similarly, when it is necessary to close the valve 102 at the opening of the hydrogen storage tank 101, the valve 102 receives a relevant control signal to close the valve 102. For example, when the vehicle is parked and turned off, the vehicle no longer needs the power system, and at this time, it is necessary to stop the hydrogen storage tank 101 from supplying hydrogen to the power system. At the same time as the vehicle is parked and turned off or within a set time thereafter, the valve 102 at the opening of the hydrogen storage tank 101 receives a control signal to close the valve 102, and the valve 102 changes from the open state to the closed state, blocking the hydrogen in the hydrogen storage tank 101 from being discharged through the valve 102 at the opening of the hydrogen storage tank 101. On the one hand, this can prevent the hydrogen from continuing to be discharged from the hydrogen storage tank 101 and causing safety hazards when the power system does not need hydrogen fuel; on the other hand, it also avoids the waste of resources caused by the continued discharge of hydrogen.

[0045] For example, the coupler 114 is installed on the pipeline. The arrangement and position of the pipeline can be adjusted according to the position of the exchangeable hydrogen storage module 1 and the disassembly assembly 2 of the vehicle 4, so that the coupler 114 can dock with the disassembly assembly 2 of the vehicle 4, thereby enabling the hydrogen storage module 1 to provide hydrogen as fuel to the power system of the vehicle 4.

[0046] With the coupler 114 connected to the disassembly / assembly assembly 2 of the vehicle 4 and the valve 102 at the opening of the hydrogen storage tank 101 open, the hydrogen in the hydrogen storage tank 101 can flow through the coupler 114 and the disassembly / assembly assembly 2 of the vehicle 4, and then enter the fuel injection port of the power system. It should be noted that even when the valve 102 at the opening of the hydrogen storage tank 101 is closed, and the exchangeable hydrogen storage module 1 is installed onto the disassembly / assembly assembly 2 of the vehicle 4 (i.e., the coupler 114 is connected to the disassembly / assembly assembly 2 of the vehicle 4), the hydrogen in the hydrogen storage tank 101 cannot be discharged from the hydrogen storage tank 101, further ensuring the safety of the hydrogen during use.

[0047] The coupler 114 can be connected to the disassembly / assembly assembly 2 of the vehicle 4 by means of snap-fit ​​or screw-on engagement, but is not limited to this. Of course, the coupler 114 can also be a ball-joint coupler 114 or a scissor-type coupler 114, etc. The type of coupler 114 can be set according to actual needs; this is merely an example and does not constitute a limitation on the scope of the claims.

[0048] The sensors in the hydrogen storage module 1 are used to detect the operating status of the hydrogen storage module 1 and can send the detection results to the control unit 103 of the hydrogen storage module 1. The sensors can be connected to the control unit 103 of the hydrogen storage module 1 via wired or wireless means to realize communication between the sensors and the control unit 103, so that the sensors can transmit the detection results detected by the hydrogen storage module 1 to the control unit 103.

[0049] The hydrogen storage module 1 can have multiple sensors to perform multi-directional detection of the hydrogen storage module 1, thereby obtaining multi-directional detection results of the hydrogen storage module 1. Based on the multi-directional detection results of the hydrogen storage module 1 obtained by the sensors, the control unit 103 can make corresponding control on the valve 102 at the opening of the hydrogen storage tank 101, so as to avoid the continued release of hydrogen in the hydrogen storage tank 101 and the resulting safety hazards in case of problems.

[0050] The sensors of the hydrogen storage module 1 can detect, but are not limited to, the pressure, force, docking with the vehicle assembly 2, and abnormal disassembly / reassembly of the hydrogen storage module 1, so as to close the valve 102 at the opening of the hydrogen storage tank 101 when any one or more of the following conditions occur:

[0051] When a collision is detected;

[0052] When an abnormal pressure is detected;

[0053] When an abnormality in the docking is detected;

[0054] And when abnormalities in disassembly or assembly are detected.

[0055] The control unit 103 of the hydrogen storage module 1 can control the valve based on the detection results of the sensor. Specifically, the control unit 103 can control the valve 102 at the opening of the hydrogen storage tank 101.

[0056] For example, the control signal received by valve 102 at the opening of hydrogen storage tank 101 can be issued by control unit 103. After receiving the detection result from the sensor, control unit 103 generates a corresponding control signal based on the received detection result and sends the control signal to valve 102 at the opening of hydrogen storage tank 101 to control the closing and opening of valve 102. Control unit 103 can be an electronic control unit (ECU) installed on hydrogen storage module 1, which can also be called a controller. Control unit 103 can be directly connected to the console in the vehicle's cab. The connection can be wired or wireless; for example, control unit 103 and the console in the cab can be connected via a wireless network. The data processing capability of the console in the cab is higher than that of control unit 103. The control unit 103 can communicate with the control console in the driver's cab. The control unit 103 can perform basic processing on the detection results from the sensors and then send the processed results to the control console in the driver's cab. The control console in the driver's cab performs more complex or further processing on the processed results from the control unit, and then generates a first control signal based on the final processing result. The control console in the driver's cab can send this first control signal to the control unit 103 of the hydrogen storage module 1, and the control unit 103 controls the valve 102 based on the first control signal. Alternatively, after receiving the first control signal, the control unit 103 of the hydrogen storage module 1 can generate a second control signal based on the first control signal, and the control unit 103 controls the valve 102 based on the second control signal.

[0057] Of course, it is understandable that the control unit 103 of the hydrogen storage module 1 may not be connected to the control console in the vehicle's cab. Another control unit can be installed on the vehicle or the vehicle's detachable assembly 2. For ease of description, the control unit 103 on the hydrogen storage module 1 is defined as the first control unit, and the other control unit on the vehicle or the vehicle's detachable assembly 2 is defined as the second control unit; the first control unit can communicate with the second control unit. The second control unit can also process relevant data from the vehicle's detachable assembly 2. Alternatively, the second processing unit can be connected to the control console in the cab as needed, using either a wired or wireless connection.

[0058] The connection between the first control unit and the second control unit can be wired or wireless; for example, they can be connected via a wireless network. The second control unit has a higher data processing capability than the first control unit. The first control unit can perform simple processing on the detection results from the sensor and then send the processing results to the second control unit. The second control unit performs more complex or further processing on the processing results from the sensor to obtain the final processing result, and generates a first control signal based on the final processing result. The second control unit can send this first control signal to the first control unit of the hydrogen storage module 1, and the first control unit controls the valve 102 based on the first control signal. Alternatively, after receiving the first control signal, the first control unit of the hydrogen storage module 1 generates a second control signal based on the first control signal, and controls the valve 102 based on the second control signal.

[0059] In addition to the two configuration methods described above, the control unit 103 of the hydrogen storage module 1 can also be configured in a way that allows it to control the valve 102 at the opening of the hydrogen storage tank 101. This is possible when the control unit 103 has sufficient data processing capabilities to control the valve 102 at the opening of the hydrogen storage tank 101. In such cases, the control unit 103 may not be connected to the control console in the driver's cab or to the second control unit mounted on the vehicle or its mounting / removal assembly 2. It can control the valve 102 at the opening of the hydrogen storage tank 101 simply by processing the relevant data. Of course, it is understood that the control unit 103 of the hydrogen storage module 1, besides controlling the valve 102 at the opening of the hydrogen storage tank 101, can also control other controlled components of the hydrogen storage module 1 as needed.

[0060] In actual operation, the control unit 103 of the hydrogen storage module 1 can process the detection results from the sensor to obtain a processing result corresponding to the detection result, and generate a first control signal based on the processing result. The control unit 103 of the hydrogen storage module 1 controls the valve 102 based on the first control signal.

[0061] The design of connecting the control unit 103 of the hydrogen storage module 1 to the control console in the cab allows for a lower configuration of the control unit 103, making full use of the existing control resources in the cab and reducing the cost of the control unit 103.

[0062] The design of connecting the control unit 103 (first control unit) of the hydrogen storage module 1 to another control unit (second control unit) installed on the vehicle or the vehicle assembly 2 can also achieve a lower configuration of the control unit 103 of the hydrogen storage module 1, make full use of the control resources of the second control unit, and reduce the cost of the control unit 103 of the hydrogen storage module 1.

[0063] By designing the control unit 103 of the hydrogen storage module 1 to be neither connected to the control console in the driver's cab nor to the second control unit installed on the vehicle or the vehicle's detachable assembly 2, independent processing of relevant data can be achieved by configuring the control unit 103 of the hydrogen storage module 1 at a higher level. Eliminating the connection between the control unit 103 of the hydrogen storage module 1 and the control console in the driver's cab, or to the second control unit, reduces connection costs and avoids potential data transmission problems when data or control signals are transmitted between different control units or between a control unit and the control console in the driver's cab. For example, data or control signals may experience delays when transmitted between the control unit 103 of the hydrogen storage module 1 and the control console in the driver's cab, affecting the control speed of valve 102. Alternatively, data loss may occur during transmission between the control unit 103 of the hydrogen storage module 1 and the control console in the driver's cab, affecting the control of valve 102. In short, shortening the data or control signal transmission path reduces potential data delays or data loss during transmission.

[0064] This embodiment controls the opening and closing of the valve 102 located at the opening of the hydrogen storage tank 101 based on the working status of the exchangeable hydrogen storage module detected by the sensor, thereby controlling the supply of hydrogen and ensuring the safety of the exchangeable hydrogen storage module.

[0065] Combination Figure 4 The sensor includes a first sensor 104. When the first sensor 104 detects that the hydrogen storage module 1 has been hit, the control unit 103 controls the valve 102 at the opening of the hydrogen storage tank 101 to close.

[0066] The first sensor 104 can be a collision sensor, which is a control signal input device for the control unit 103. Its function is to detect the intensity signal of the collision when the hydrogen storage module 1 of the vehicle receives a collision, and input the signal to the control unit 103. The control unit 103 determines whether to send a closing signal to the valve 102 at the opening of the hydrogen storage tank 101 based on the collision intensity signal sent by the collision sensor.

[0067] For example, the control unit 103 can preset a collision intensity value. When the control unit 103 receives the collision intensity signal sent by the collision sensor, the control unit 103 compares the collision intensity value represented by the received collision intensity signal with the preset collision intensity value and generates a corresponding control signal based on the comparison result.

[0068] The control signal can be a closing signal that controls the valve 102 at the opening of the hydrogen storage tank 101 to close, or it can be a control signal that is not used to close the valve 102 at the opening of the hydrogen storage tank 101, but is only used to provide feedback on the collision intensity signal sent by the sensor received by the control unit 103.

[0069] For example, if the collision intensity value represented by the collision intensity signal received by the control unit 103 is less than the preset collision intensity value, it indicates that the collision intensity received by the hydrogen storage module 1 is small, and the impact on the hydrogen storage tank 101 is small or will not have a direct impact on the hydrogen storage tank 101. At this time, the control unit 103 can generate a corresponding control signal, which indicates that the control unit 103 has received the collision intensity signal sent by the collision sensor, but the collision does not affect the normal use of the hydrogen storage module 1.

[0070] Specifically, a display can be installed on the hydrogen storage module 1 to show the control signals from the control unit 103, so that vehicle occupants can clearly understand the result of the collision. This display can be installed on, but is not limited to, the hydrogen storage module 1, or in the vehicle's driver's cab, or directly utilize the existing display in the vehicle's driver's cab. The display on the hydrogen storage module 1 can also be connected to the display in the vehicle's driver's cab, allowing occupants to be informed of the status of the hydrogen storage module 1 in a timely manner.

[0071] Of course, the control unit 103 can also generate a first alarm signal based on the above comparison results and send the first alarm signal to the display so that the vehicle user can see the status of the hydrogen storage module 1 and take corresponding processing measures for the hydrogen storage module 1 based on the first alarm signal. For example, if the display shows the first alarm signal while the vehicle is in motion, even if the collision intensity of the hydrogen storage module 1 is small, the vehicle user can stop and check after driving to a safe position to ensure that the hydrogen in the hydrogen storage tank 101 will not leak and avoid safety accidents caused by hydrogen leakage.

[0072] If the collision intensity value represented by the collision intensity signal received by the control unit 103 is greater than or equal to the preset collision intensity value, it indicates that the hydrogen storage module 1 has experienced a large collision intensity, which has a significant impact on the hydrogen storage tank 101 and may directly cause deformation of the hydrogen storage tank 101 or leakage of hydrogen gas inside the hydrogen storage tank 101. In this case, the control unit 103 can generate a corresponding control signal and send it to the valve 102 at the opening of the hydrogen storage tank 101 to close the valve 102. In addition, the control unit 103 can simultaneously generate a second alarm signal and send it to the display to inform the vehicle user of the specific situation of the hydrogen storage module 1 immediately, so as to take corresponding measures as soon as possible to avoid a safety accident caused by hydrogen leakage. For example, if the display shows the second alarm signal while the vehicle is in motion, the vehicle user should stop the vehicle in a safe location as soon as possible after seeing the second alarm signal and have the vehicle repaired or wait for professional repair personnel.

[0073] Collision sensors can employ an inertial mechanical switch structure, essentially functioning as a control switch, with their operating state depending on the magnitude of acceleration during a collision. Collision sensors can be mechanical or electronic. Mechanical types include ball-type, roller-type, and eccentric ball-type sensors. This is merely an example and does not constitute a limitation on the scope of the claims.

[0074] The collision sensor can be a collision signal sensor or a collision protection sensor. The purpose of setting up the protection sensor is to prevent the collision sensor from accidentally short-circuiting and causing abnormal detection results, which in turn affects the control unit 103's control of the valve 102 at the opening of the hydrogen storage tank 101.

[0075] The collision sensor can be directly mounted on the hydrogen storage tank 101 or on the housing 109 used to house the hydrogen storage tank 101. Multiple collision sensors can be included, and they can be positioned at different locations on the housing 109; for example, collision sensors can be spaced out around the housing 109. Each collision sensor has a corresponding number so that the control unit 103 can receive the detection results from the corresponding numbered collision sensor. When sending a corresponding alarm signal to the display, the control unit 103 can simultaneously send the corresponding collision sensor number, allowing vehicle users to clearly identify which part of the hydrogen storage module 1 has been impacted, thus enabling faster location of the collision and timely implementation of appropriate handling measures.

[0076] In some embodiments, combined with Figure 4 The sensor includes a second sensor. When the second sensor detects an abnormal pressure in the hydrogen storage module 1, the control unit 103 controls the valve 102 at the opening of the hydrogen storage tank 101 to close.

[0077] Specifically, the second sensor can be a pressure sensor, specifically a high-pressure sensor 105 and / or a medium-pressure sensor 106, etc. The appropriate type of sensor can be selected based on its location. The second sensor can be installed at the opening of the hydrogen storage tank 101, or it can be installed on the hydrogen flow pipeline between the hydrogen storage tank 101 and the power system.

[0078] For example, a pressure reducing valve 113 is installed on the hydrogen flow pipeline to allow the hydrogen to be depressurized before being used as fuel for the power system. A high-pressure sensor 105 can be installed at the opening of the hydrogen storage tank 101, inside the hydrogen storage tank 101, or near the opening of the hydrogen flow pipeline (between the hydrogen storage tank 101 and the pressure reducing valve 113) to detect the pressure value of the hydrogen storage tank 101. The control unit 103 can preset a high-pressure value for the hydrogen storage tank 101. The high-pressure sensor 105 detects the pressure value of the hydrogen storage tank 101 and sends the detection result to the control unit 103. After receiving the pressure detection result from the high-pressure sensor 105, the control unit 103 compares it with the preset high-pressure value to obtain a comparison result. The control unit 103 generates a corresponding control signal based on the high-pressure value comparison result.

[0079] When the pressure value indicated by the pressure detection result from the high-pressure sensor 105 received by the control unit 103 is greater than the preset high-pressure value, the control unit 103 generates a closing signal to close the valve 102 at the opening of the hydrogen storage tank 101, and sends the closing signal to the valve 102 at the opening of the hydrogen storage tank 101. The valve 102 closes in response to the closing signal. At the same time, the control unit 103 can also generate a corresponding alarm signal and send the alarm signal to the display to inform the vehicle user that the pressure of the hydrogen storage tank 101 has exceeded the preset high-pressure value. The vehicle user can take corresponding measures based on the alarm signal.

[0080] For example, if the temperature of the hydrogen storage tank 101 is too high, the pressure inside the hydrogen storage tank 101 may increase, causing the pressure value detected by the high pressure sensor 105 of the hydrogen storage tank 101 to be greater than the preset high pressure value. The pressure of the hydrogen storage tank 101 can be reduced by cooling the hydrogen storage tank 101.

[0081] The control unit 103 can also assess the remaining amount of hydrogen in the hydrogen storage tank 101 based on the pressure value of the high pressure sensor 105. When the remaining amount of hydrogen in the hydrogen storage tank 101 is small or the hydrogen in the hydrogen storage tank 101 is turned off, the control unit 103 can also send a closing signal to close the valve 102 at the opening of the hydrogen storage tank 101.

[0082] For example, a medium-pressure sensor 106 can be installed on the hydrogen flow pipeline between the hydrogen storage tank 101 and the power system. Hydrogen in the storage tank 101, after being depressurized, is transported through the hydrogen flow pipeline to the fuel injection port of the vehicle's power system to provide fuel. The medium-pressure sensor 106 detects the pressure value in the hydrogen flow pipeline and sends the detection result to the control unit 103. Similarly, a preset medium-pressure value can be preset in the control unit 103. The preset medium-pressure value can be lower than the preset high-pressure value, and the preset medium-pressure value can be higher than atmospheric pressure. After receiving the pressure detection result from the medium-pressure sensor 106, the control unit 103 compares it with the preset medium-pressure value to obtain a comparison result. The control unit 103 generates a corresponding control signal based on the comparison result of the medium-pressure values. The medium-pressure sensor 106 can detect whether the pressure of the hydrogen supplied to the power system is appropriate.

[0083] For example, if the pressure value detected by the high-pressure sensor 105 received by the control unit 103 is greater than the preset high-pressure value, it indicates that the pressure of the hydrogen supplied by the hydrogen storage tank 101 to the power system is too high. A pressure reduction measure can be taken to lower the pressure in the hydrogen flow pipeline, ensuring that the hydrogen in the storage tank 101 is supplied to the power system at a suitable pressure. Specifically, a pressure reducing valve 113 can be installed on the hydrogen flow pipeline. The control unit 103 can send a corresponding control signal to the pressure reducing valve 113 to adjust its opening, thereby controlling the pressure in the hydrogen flow pipeline. During the adjustment process, the medium-pressure sensor 106 continuously detects the pressure in the hydrogen flow pipeline and sends the detection result to the control unit 103. The control unit 103 generates a corresponding control signal in real time based on the detection result of the medium-pressure sensor 106, and controls the opening of the pressure reducing valve 113 in real time to adjust the pressure in the hydrogen flow pipeline to a suitable value as quickly as possible.

[0084] Of course, if a serious leak occurs in the hydrogen flow pipeline, the pressure value detected by the medium pressure sensor 106 may be close to or equal to atmospheric pressure. In this case, the control unit 103 can generate an alarm signal based on the detection result received from the medium pressure sensor 106, and the vehicle user can take corresponding measures based on the alarm signal.

[0085] For example, the control unit 103 can send a closing signal to the valve 102 at the opening of the hydrogen storage tank 101 to close the valve 102 at the opening of the hydrogen storage tank 101. Multiple hydrogen storage tanks 101 can correspond to multiple branches of hydrogen flow pipelines, with each branch converging into a main pipe at the fuel injection port of the power system. Based on the above detection results, the branch of the hydrogen flow pipeline corresponding to the current hydrogen storage tank 101 can be inspected or replaced at an appropriate time. The control unit 103 can send a closing signal to the valve 102 at the opening of all hydrogen storage tanks 101 and stop the machine for inspection. If a leak occurs in the main pipe, the main pipe can be replaced.

[0086] The sensors in the hydrogen storage module 1 may also include a temperature sensor, which is used to detect the temperature of the hydrogen storage tank 101. The temperature sensor can be located on the outer surface of the hydrogen storage tank 101. When the temperature sensor detects that the temperature of the hydrogen storage tank 101 is too hot or too cold, it can limit the amount of hydrogen used and protect the tank.

[0087] For example, the control unit 103 can preset a first temperature value and a second temperature value, where the first temperature value is higher than the second temperature value. The temperature sensor can send the detected temperature of the hydrogen storage tank 101 to the control unit 103. The control unit 103 compares the received temperature value of the hydrogen storage tank 101 from the temperature sensor with the first and second temperature values. If the temperature of the hydrogen storage tank 101 detected by the temperature sensor is higher than the first temperature value, it indicates that the temperature of the hydrogen storage tank 101 is too high; if the temperature of the hydrogen storage tank 101 detected by the temperature sensor is lower than the second temperature value, it indicates that the temperature of the hydrogen storage tank 101 is too low. Both of these situations require control of the amount of hydrogen used.

[0088] In some embodiments, the sensor includes a third sensor (not shown) that when the third sensor detects an abnormality in the docking of the coupler 114 with the vehicle's disassembly assembly 2, the control unit 103 controls the valve 102 at the opening of the hydrogen storage tank 101 to close.

[0089] The third sensor can be a connection sensor or a position sensor, etc. For example, the third sensor can be a proximity switch, which can be installed on the coupler 114 of the vehicle's disassembly / reassembly assembly 2 or the hydrogen storage module 1. The proximity switch is used to detect the distance between a certain position of the coupler 114 and the proximity switch. For example, the proximity switch sends the detection result to the control unit 103. If the distance between the aforementioned certain position of the coupler 114 and the vehicle's disassembly / reassembly assembly 2 is zero, it indicates that the coupler 114 and the vehicle's disassembly / reassembly assembly 2 have successfully docked; otherwise, it indicates that the docking of the coupler 114 and the vehicle's disassembly / reassembly assembly 2 is abnormal.

[0090] In practical use, the coupler 114 connects normally with the vehicle's assembly / disassembly component 2, and the valve 102 at the opening of the hydrogen storage tank 101 opens to provide fuel to the vehicle's power system. The proximity switch transmits the detection results to the control unit 103 in real time. When the control unit 103 determines that the distance between the proximity switch detecting the aforementioned determined position of the coupler 114 and the vehicle's assembly / disassembly component 2 is greater than zero, it indicates that the coupler 114 may be loose. At this time, the control unit 103 can send a closing signal to the valve 102 at the opening of the hydrogen storage tank 101 to close the valve 102 at the opening of the hydrogen storage tank 101, thereby preventing hydrogen leakage and safety hazards.

[0091] Similarly, the control unit 103 can also send an alarm signal to the display so that the vehicle user is aware that the coupler 114 is loose, so that the coupler 114 can be reconnected to the vehicle's disassembly and assembly 2 as soon as possible.

[0092] In some embodiments, combined with Figure 4 The sensor includes a fourth sensor 107. When the fourth sensor 107 detects an abnormality in the disassembly or assembly of the hydrogen storage module 1, the control unit 103 controls the valve 102 at the opening of the hydrogen storage tank 101 to close.

[0093] The fourth abnormality sensor can be a weight sensor, torque sensor, etc. The fourth sensor 107 is disposed between the hydrogen storage module 1 and the vehicle assembly / disassembly assembly 2, and is located at the point of contact between the two. For example, when the hydrogen storage module 1 is normally installed in the vehicle assembly / disassembly assembly 2, the weight sensor detects a first weight value, which is a value greater than zero; however, when the hydrogen storage module 1 is detached from the vehicle assembly / disassembly assembly 2 or becomes loose from it, the weight sensor detects a second weight value, which is zero, or a value much smaller than the first weight value. The weight sensor sends the detection result to the control unit 103. The control unit 103 can generate a corresponding control signal based on the detection result of the weight sensor. When the hydrogen storage module 1 is detached from the vehicle's disassembly assembly 2 or becomes loose from the vehicle's disassembly assembly 2, the control unit 103 sends a shut-off signal to the hydrogen storage tank 101 that is currently supplying fuel to the power system. More specifically, the control unit 103 sends a shut-off signal to the valve 102 at the opening of the hydrogen storage tank 101 to stop the hydrogen storage tank 101 from supplying fuel to the power system and prevent hydrogen leakage caused by the loosening of the hydrogen storage module 1.

[0094] In some embodiments, combined with Figure 4 The exchangeable hydrogen storage module 1 also includes a power supply 108. The power supply may be, but is not limited to, a low-voltage power supply, and of course, other power supply forms may also be used. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0095] The power supply 108 can be installed on the housing 109 of the hydrogen storage module 1. A mounting position for the power supply 108 can be reserved on the housing 109. A protective shell can be installed on this mounting position to protect the power supply 108 and prevent it from being damaged.

[0096] In some embodiments, combined with Figure 4 The exchangeable hydrogen storage module 1 also includes a first electrical energy device. This first electrical energy device can be used to obtain electrical energy from inside the vehicle to charge the power source 108. The first electrical energy device can be disposed on the housing 109 of the hydrogen storage module or at other locations on the hydrogen storage module. Preferably, the first electrical energy device can be disposed on the hydrogen storage module near the power source 108 to facilitate its charging of the power source 108.

[0097] For example, the first electrical energy device can be a vibration power generation device, which can include a vibration generator. The vibration generator utilizes the principle of electromagnetic induction, causing relative motion between a magnet and a coil through vibration, thereby generating an induced current in the coil. The vibration generator can include a magnet, a coil, and a vibration source. When the vibration source vibrates, the magnet vibrates accordingly, forming a changing magnetic field with the fixed or relatively moving coil, thus generating an induced electromotive force in the coil, and consequently producing electrical energy. The first electrical energy device converts the obtained electrical energy to charge the power supply 108.

[0098] The first electrical energy device can also be an energy conversion device, which may include a kinetic energy recovery module. The kinetic energy recovery module can perform kinetic energy collection, kinetic energy transmission, and kinetic energy conversion processes. The kinetic energy recovery module can utilize the vehicle's inertia to drive a generator, recovering the energy generated during braking and charging the power source 108 with the electrical energy generated by the generator. The intensity and method of kinetic energy recovery can be adjusted according to the vehicle's speed and the driver's operation.

[0099] For example, when a vehicle brakes, decelerates, or goes downhill, it generates a significant amount of kinetic energy. The kinetic energy recovery module captures this kinetic energy through a kinetic energy collection device. The collected kinetic energy is then transmitted to an energy conversion device via a transmission mechanism. In the energy conversion device, the kinetic energy is converted into electrical energy. For example, a generator converts kinetic energy into electrical energy using the principle of electromagnetic induction, generating current and voltage. The kinetic energy recovery module can be connected to the power supply 108 on the hydrogen storage module 1 to charge the power supply 108 with the converted electrical energy for energy storage.

[0100] A kinetic energy recovery module may include a kinetic energy harvesting device, a transmission mechanism, and an energy conversion device. The kinetic energy harvesting device is responsible for capturing and collecting kinetic energy in the form of wheel motion, etc. In a vehicle, this could be the vehicle's wheels, which generate kinetic energy during vehicle movement or braking. The transmission mechanism transfers the collected kinetic energy to the energy conversion device. In a vehicle, this can be achieved through mechanical connections (such as gears, chains, or belts) to ensure smooth kinetic energy transmission. The energy conversion device is the core component of the kinetic energy recovery module, responsible for converting kinetic energy into electrical energy. The energy conversion device may include, but is not limited to, a generator. The generator converts kinetic energy into electrical energy through the principle of electromagnetic induction.

[0101] Of course, the power supply 108 can also be connected to the vehicle's power supply to charge the power supply 108 on the hydrogen storage module 1 through the vehicle's power supply.

[0102] In some embodiments, the exchangeable hydrogen storage module further includes a second electrical power device for obtaining electrical energy from outside the vehicle to charge the power source.

[0103] For example, the second electrical energy device can be a solar power generation device, which can include a solar panel 110, which can be, but is not limited to, mounted on the housing 109 of the hydrogen storage module 1.

[0104] The solar panel 110 can be connected to the power source 108. When the solar panel 110 receives sunlight, it converts solar energy into electrical energy to charge the power source 108.

[0105] The solar panel 110 is also connected to the power source 108 to charge the power source 108. Even when the vehicle is off, the solar panel 110 can charge the power source 108 as long as the vehicle is in a sunny outdoor location.

[0106] Of course, it is understandable that the solar panel 110 can also be connected to the control unit 103 and / or sensors to directly power the control unit 103 and sensors.

[0107] The solar panel 110 may include one or more panels. When there is only one solar panel 110, it can be positioned on top of the housing 109. When there are two or more solar panels 110, they can be positioned on top of the housing 109, on the side of the housing 109, etc. Alternatively, the solar panel can be positioned in a location that receives sunlight more easily, depending on the relative position of the hydrogen storage module 1 and the vehicle.

[0108] The second electrical energy device can also be a charging receiver. This receiver can be connected to a charging station or charging pile, or power supply equipment within the exchange station, to receive electrical energy from the charging station or charging pile, or power supply equipment, and then use that energy to charge the power supply 108 on the hydrogen storage module 1. Alternatively, the aforementioned charging station or charging pile, or power supply equipment, may not be located within the exchange station. For example, when replacing the hydrogen storage module 1 within the exchange station, the exchange station has a designated location for the hydrogen storage module 1, equipped with a charging base. This charging base can have a charging plug or similar structure compatible with the charging receiver on the hydrogen storage module 1. During the time the hydrogen storage module 1 is placed in the exchange station, the power supply 108 of the hydrogen storage module 1 can be charged via the second electrical energy device.

[0109] In some embodiments, combined with Figure 4 When the power supply 108 of the switching hydrogen storage module 1 uses a low-voltage power supply, the switching hydrogen storage module 1 also includes a low-voltage connector 111. The low-voltage connector 111 is used to transmit the vehicle's power to the power supply 108 and also for communication with the control unit. The low-voltage connector 111 is used to operate in a low-voltage environment and includes a plug (female) and a socket (male). It is connected by plugging and unplugging to achieve stable and reliable transmission of current and signals, while ensuring the safety and stability of the circuit.

[0110] The low-voltage connector 111 is connected to the sensor and control unit 103 to reliably transmit the sensor's detection signal to the control unit 103.

[0111] In some embodiments, combined with Figure 1 The exchangeable hydrogen storage module 1 also includes a prompting unit, which is used to prompt the user with the sensor's detection results.

[0112] For example, the notification unit can connect to the sensor via wired or wireless transmission to receive the sensor's detection results. The notification unit can directly display the sensor's detection results to the user, allowing the user to intuitively understand the current operating status of the hydrogen storage module 1 and take timely appropriate action based on the operating status.

[0113] In addition, the prompting unit can also be connected to the control unit 103 to receive control signals from the control unit 103.

[0114] The notification unit includes a display, which can be configured not only to display alarm signals from the control unit 103 so that vehicle users can clearly know the abnormality of the hydrogen storage module 1, but also to display the remaining amount of hydrogen in the hydrogen storage tank 101, the predicted hydrogen supply time, etc., to improve the ease of use of the hydrogen storage module 1.

[0115] The warning unit can be installed on the housing 109 of the hydrogen storage module 1, or it can be installed in the vehicle's driver's cab; alternatively, warning units can be installed in both the hydrogen storage module 1 and the vehicle's driver's cab. For example, the first warning unit 112 installed on the housing 109 of the hydrogen storage module 1 can emit an audible alarm. The first warning unit 112 is interconnected with a second warning unit installed in the vehicle's driver's cab, and the second warning unit can display an abnormal alarm signal. For example, a red alarm signal can be continuously flashed on the display.

[0116] This application also provides a vehicle, which can be a heavy-duty truck or other large commercial vehicle; this application does not specifically limit this. The vehicle includes an exchangeable hydrogen storage module 1 as described in any of the above embodiments. Figure 2 and ​ As shown, the vehicle also includes a disassembly and assembly component 2 adapted to the exchangeable hydrogen storage module 1. The vehicle uses the disassembly and assembly component 2 to install and remove the exchangeable hydrogen storage module 1. Vehicles using the aforementioned exchangeable hydrogen storage module 1 facilitate fuel replacement. When the hydrogen fuel in the vehicle's power system is depleted or the available hydrogen supply is low, the hydrogen storage module 1 can be replaced promptly to ensure the vehicle's normal operation. Furthermore, vehicles using the aforementioned hydrogen storage module 1 continuously monitor its operational status, ensuring the safety of the exchangeable hydrogen storage module as much as possible.

[0117] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
