[0037] The present invention is further described in detail below with reference to specific examples. These examples should not be construed as limiting the scope of protection claimed in the present invention.

[0038] Figure 1 A front view of a solid-state hydrogen storage device based on zoning management provided by an embodiment of the present invention, Figure 2 A top view of a solid-state hydrogen storage device based on zoning management provided in an embodiment of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the solid-state hydrogen storage device based on zoning management provided in an embodiment of the present invention includes a housing 1 and a hydrogen storage container 2 disposed within the housing 1. A cooling medium cavity 3 is located between the housing 1 and the hydrogen storage container 2, and M cooling medium release devices 4 are disposed on the inner wall of the cooling medium cavity 3. The interior of the hydrogen storage container 2 is longitudinally divided into N mutually independent hydrogen storage areas 5, each of which contains solid-state hydrogen storage material. At least one cooling medium release device 4 is disposed in each hydrogen storage area 5, where M and N are integers greater than or equal to 2, and M is not less than N.

[0040] In one embodiment of the present invention, the hydrogen storage container 2 is further provided with a hydrogen charging and discharging port 6, a stepping rotary motor 7, and a sealing device 8. The sealing device 8 has a 1 / N opening and is rotatably disposed at the opening of each hydrogen storage area 5 to seal the opening of each hydrogen storage area 5. The stepping rotary motor 7 is used to drive the sealing device 8 to rotate so that with each rotation of the sealing device 8, the 1 / N opening is aligned with the opening of a hydrogen storage area 5. The hydrogen charging and discharging port 6 is connected to the 1 / N opening of the sealing device 8.

[0041] Exemplarily, the shell 1 may be in the shape of a rectangular parallelepiped, and its material may be metal, which mainly plays the function of overall support and sealing. The hydrogen storage container 2 may be a hydrogen storage bottle. The gap between the shell 1 and the hydrogen storage container 2 constitutes a cooling medium cavity 3, on the inner wall of which are provided with four cooling medium release devices 4 (#1P, #2P, #3P, #4P). The interior of the hydrogen storage container 2 is longitudinally divided into four independent hydrogen storage areas 5 (#1C, #2C, #3C, #4C). The four cooling medium release devices 4 are respectively provided corresponding to the four hydrogen storage areas 5. The outlet of the cooling medium release device 4 is directly facing the hydrogen storage area 5 to ensure that the released cooling medium can quickly cover the corresponding area.

[0042] Accordingly, the sealing device 8 has a quarter opening, and the operating state of the four hydrogen storage areas 5 is switched by a stepping rotary motor 7 in conjunction with the sealing device 8. The stepping rotary motor 7 drives the sealing device 8 to rotate 90 degrees, selecting one hydrogen storage area 5 in turn for charging or discharging hydrogen, while the remaining areas are sealed to ensure that the reaction only occurs in the selected area.

[0043] In one embodiment of the present invention, the solid-state hydrogen storage device further includes a cooling medium storage container 9. The cooling medium storage container 9 is disposed above the housing 1. The cooling medium storage container 9 is in communication with each cooling medium release device 4 and is configured to provide cooling medium to the cooling medium release device 4. A heating device 10 is disposed in the cooling medium storage container 9.

[0044] Exemplarily, the cooling medium storage container 9 may be a water tank for storing coolant. The heating device 10 may be a heating wire. When the hydrogen storage device is in the hydrogen release state, the heating wire is activated to heat the coolant to a set temperature (e.g., 50°C), supplying the heat required by the hydrogen storage material to maintain the hydrogen release rate. The cooling medium may be cooling water, and the cooling medium release device 4 may be a spray head for spraying cooling water onto the outer wall of the corresponding hydrogen storage area 5.

[0045] In one embodiment of the present invention, the solid-state hydrogen storage device further includes a coolant collection device. This coolant collection device is located below the hydrogen storage container 2 and includes a coolant collection container 11, a liquid level sensor 12, and a power unit 13. The liquid level sensor 12 is used to detect the liquid level of the coolant in the coolant collection container 11, and the power unit 13 is used to transport the coolant from the coolant collection container 11 to the coolant storage container 9.

[0046] In one embodiment of the present invention, a plurality of temperature sensors 14 are provided on the outer wall of the hydrogen storage container 2. The temperature sensors 14 are used to detect the surface temperature of the hydrogen storage container 2. At least one temperature sensor 14 is provided for each hydrogen storage area 5.

[0047] For example, the temperature sensor 14 can be a thermistor, specifically an NTC B3435 10K thermistor, for temperature monitoring. There can be four thermistors (#1N, #2N, #3N, #4N), corresponding to the four hydrogen storage areas 5 (#1C, #2C, #3C, #4C), respectively. The thermistors, protected by a thin film seal, are attached to the outer wall of the hydrogen storage container 2, ensuring close contact between the two to ensure accurate temperature monitoring and rapid response.

[0048] In one embodiment of the present invention, in order to achieve the purpose of intelligent temperature control, the solid-state hydrogen storage device also includes a controller (not shown in the figure), which is electrically connected to the cooling medium release device 4, the stepping rotary motor 7, the heating device 10, the liquid level sensor 12, the power device 13 and the temperature sensor 14 respectively.

[0049] In one embodiment of the present invention, the controller is capable of obtaining the surface temperature of the hydrogen storage container 2 detected by the temperature sensor 14, and controlling the heating device 10, the cooling medium release device 4, and the stepping rotary motor 7 to turn on or off when the surface temperature of the hydrogen storage container 2 is higher or lower than a preset temperature.

[0050] In addition, the controller can obtain the liquid level of the cooling medium in the cooling medium collecting container 11 detected by the liquid level sensor 12, and when the liquid level is higher than the preset liquid level, control the power device 13 to turn on to transport the cooling medium in the cooling medium collecting container 11 to the cooling medium storage container 9.

[0051] In one embodiment of the present invention, when the solid-state hydrogen storage device is in a hydrogen charging state, the controller controls the heating device 10 to be turned off, and controls the stepping rotary motor 7 to start so that the 1 / N opening of the sealing device 8 is aligned with the opening of one of the hydrogen storage areas 5 to perform hydrogen charging; when the surface temperature of the hydrogen storage area 5 in the hydrogen charging state is higher than a first preset temperature, the cooling medium release device 4 is controlled to release the cooling medium; when the surface temperature of the hydrogen storage area 5 in the hydrogen charging state is higher than a second preset temperature, the stepping rotary motor 7 is controlled to start again so that the 1 / N opening of the sealing device 8 is aligned with the opening of the next hydrogen storage area 5 to perform hydrogen charging;

[0052] In addition, when the solid-state hydrogen storage device is in a hydrogen release state, the controller controls the heating device 10 to turn on, heats the cooling medium in the cooling medium storage container 9 to a third preset temperature, and controls the stepping rotary motor 7 to start so that the one-N opening of the closing device 8 is aligned with the opening of one of the hydrogen storage areas 5, and at the same time controls the cooling medium release device 4 to release the heated cooling medium.

[0053] The following describes some specific structures and working principles of the solid-state hydrogen storage device involved in the embodiments of the present invention:

[0054] 1. Mechanical structure of the device

[0055] 1.1. Partitioned hydrogen storage bottles:

[0056] The interior of the hydrogen storage bottle is evenly divided into four independent storage areas, numbered #1C, #2C, #3C, and #4C. Each storage area is structurally isolated from the others to prevent heat transfer interference and gas mixing. A stepper motor is connected to the bottle's mouth, which rotates a 1 / 4-inch closed mouth. Each 90-degree rotation precisely aligns any hydrogen storage area, enabling hydrogen charging and discharging operations in a specific area while keeping other areas sealed.

[0057] 1.2. Stepper rotary motor and closed mouth assembly:

[0058] A stepper motor is installed at the mouth of the hydrogen storage bottle. It drives a quarter-opening seal, whose structure corresponds to the hydrogen storage area divisions within the bottle. During the charging and discharging process, the stepper motor rotates 90 degrees each time, switching the seal's opening to a different hydrogen storage area, allowing hydrogen to be charged and discharged sequentially. This allows for independent control of each area during the hydrogen charging and discharging process, preventing overheating during the charging process.

[0059] 1.3, Temperature detection system:

[0060] NTC B3435 10K thermistors (numbered #1N, #2N, #3N, and #4N) are installed on the outer wall of each hydrogen storage area to monitor the surface temperature in real time. Each thermistor is wrapped in plastic film into a thin sheet that adheres closely to the metal surface of the hydrogen storage tank. They offer high sensitivity, waterproofing, and insulation. The thermistors transmit temperature data to the controller, which adjusts the sprinkler head's operating state based on temperature fluctuations.

[0061] 1.4. Partitioned spray cooling / heating system:

[0062] The hydrogen storage tank is equipped with four spray heads, numbered #1P, #2P, #3P, and #4P, corresponding to the outer surfaces of the four hydrogen storage areas. When the temperature of a hydrogen storage area exceeds a preset value (e.g., 35°C), the controller activates the corresponding spray head to cool that area. When the temperature in that area returns to 25°C, the spray head automatically stops.

[0063] The spray cooling / heating system includes a top-mounted water tank for storing cooling or heating water. During hydrogen discharge, the controller heats the water to the appropriate temperature via a heating wire within the tank, providing heated water to the hydrogen storage bottle to supplement the heat absorption required during the discharge process and ensure a stable discharge rate.

[0064] 1.5. Water storage tank and water circulation system:

[0065] A water tank, equipped with a heater wire, is installed on top of the hydrogen storage unit to store water for cooling and heating. A water collection tank, installed at the bottom of the unit, collects the sprayed water. The tank houses a float level sensor and a DC water pump. When the water level in the collection tank reaches 3 / 4 full, the float level sensor triggers a controller to activate the DC water pump, pumping water from the collection tank back into the storage tank. When the level falls below 1 / 4, the DC water pump stops. This water circulation system reduces cooling water loss and ensures a continuous water supply.

[0066] 2. Circuit composition

[0067] 2.1、Controller:

[0068] The controller receives data from thermistors in each zone, determines the temperature of each zone, and controls the operating state of the stepper motor and sprinkler head to achieve dynamic temperature balance in each zone. The controller connects to the stepper motor, controlling its rotation angle to switch the hydrogen storage area between charging and discharging. It also regulates the stepper motor's frequency according to a pre-set program to ensure optimal time and temperature conditions for each charge and discharge.

[0069] 2.2 Temperature monitoring and feedback loop:

[0070] Each thermistor is connected to a controller, transmitting real-time temperature data. The controller uses this temperature feedback to regulate the showerhead, ensuring the temperature remains within a preset safe range during hydrogen charging or de-charging.

[0071] 2.3 Water tank level monitoring and circulation control circuit:

[0072] The float level sensor in the water collection tank is connected to the controller. When the water level is too high, a DC water pump is activated to pump the water in the water collection tank back to the top water storage tank, forming a closed loop. This circuit is also connected to the water tank heater to heat the water source in the water storage tank during hydrogen discharge, providing hot water spray for the hydrogen discharge area.

[0073] 3. Operation steps

[0074] 3.1. Hydrogen charging process:

[0075] The controller activates the stepper motor, aligns the 1 / 4-open seal with the #1C area, and begins charging hydrogen into the #1C area. The controller monitors the temperature of the #1C area using the #1N thermistor. When the temperature exceeds 35°C, the controller activates the #1P spray head for cooling. When the temperature continues to rise to 55°C, the controller controls the stepper motor to rotate 90 degrees, switching the hydrogen charging area to #2C. Simultaneously, the #1P spray head continues to cool the #1C area until the temperature returns to 25°C.

[0076] 3.2 Hydrogen release process:

[0077] The controller aligns the stepper motor with the area to be dehydrogenated. Since the hydrogen storage material absorbs heat during dehydrogenation, the controller activates the heating wire inside the water storage tank, heating the spray water into hot water. This hot water is then sprayed onto the outer wall of the dehydrogenation area through the corresponding spray nozzle, providing the necessary heat for the dehydrogenation process and ensuring a stable dehydrogenation rate.

[0078] 3.3 Dynamic switching control of hydrogen charging process:

[0079] Through the coordination of the controller and stepper motor, when the temperature reaches a specified upper limit (e.g., 55°C), the system automatically switches the hydrogen charging zone to ensure that each charging zone is at the optimal temperature. In this way, the hydrogen charging zone switches sequentially between the zones, ensuring that each zone has sufficient cooling time to return to the appropriate hydrogen charging temperature during the switching cycle.

[0080] When the system completes a hydrogen charging cycle in the #4C area, the status of the four areas in the hydrogen storage bottle are: #1C is in standby state, #2C and #3C are in spray cooling recovery state, and #4C is in hydrogen charging device state.

[0081] The above steps will be repeated in the same sequence to ensure that there is always a partition in the hydrogen charging state, and the area in the cooling and recovery state can enter the next hydrogen charging at the optimal temperature.

[0082] Through this sequential, zoned hydrogen charging and cooling control, the hydrogen charging area can be consistently maintained at an appropriate temperature to achieve the optimal hydrogen charging rate. At the same time, by preventing the hydrogen storage material from continuously operating at high temperatures, the degradation of the material's hydrogen absorption performance and hydrogen storage stability issues caused by excessive temperatures are avoided, ensuring the efficient and safe operation of the entire hydrogen storage device.

[0083] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
