[0002] With the continuous development of the hydrogen energy industry, control systems for hydrogen filling and release based on solid-state hydrogen storage will have broad application prospects and market demand. These control systems are a crucial component of hydrogen energy utilization systems, responsible for efficiently and safely filling hydrogen into solid-state hydrogen storage devices and releasing it when needed, supplying it to downstream hydrogen-using equipment via manifolds. In solid-state hydrogen storage systems, the hydrogen input and output control system not only undertakes the tasks of hydrogen filling and release but also ensures the safety and stability of hydrogen transmission.

[0003] However, existing hydrogen energy input and output control system designs often employ a control scheme where hydrogen charging is used for cooling and hydrogen release is used for heating. This results in high energy consumption and low energy utilization efficiency in the cold and hot cycle device. Summary of the Invention

In the hydrogen energy output mode, the control motherboard controls the hydrogen filling port to close, the cylinder valve to activate the hydrogen releasing mode, the pressure reducing valve to open, the temperature sensor and pressure sensor to always operate, and controls the start and stop of the hot and cold circulation device according to the temperature value T and the pressure value P. In the idle mode, the control motherboard controls the hydrogen production device, cylinder valve, hot and cold circulation device, temperature sensor, and pressure sensor to be in a closed state.

[0035] To avoid confusion with the present invention, some technical features known in the art have not been described.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment provides a hydrogen energy input and output control system, including a busbar 100, a hot and cold circulation device 200, a temperature sensor 300, a pressure sensor 400, and a control motherboard.

[0038] The hydrogen filling port of the manifold 100 is connected to an upstream hydrogen production device (e.g., a PEM electrolyzer); multiple bottle valves 130 of the manifold 100 are connected one-to-one with multiple hydrogen storage devices to form a hydrogen passage between them and the hydrogen storage devices (e.g., hydrogen storage cylinders); the bottle valves 130 include a hydrogen filling mode and a hydrogen discharging mode, and are communicatively connected to the control main board to realize the hydrogen filling and discharging of the hydrogen storage devices; the pressure reducing valve 140 of the manifold 100 is connected to a downstream hydrogen consumption device to supply hydrogen gas that meets the hydrogen consumption pressure requirements to the hydrogen consumption device.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the manifold 100 includes a valve array 110, bottle valves 130, and pressure reducing valves 140. The valve array 110 includes a base 111, a first valve 112, a second valve 113, and multiple third valves 114. The base 111 has a hydrogen supply port connected to the first valve 112 and a hydrogen filling port connected to the second valve 113 at both ends along its length, and multiple vent ports corresponding to the third valves 114 at its upper end. The hydrogen supply port, hydrogen filling port, and vent ports are interconnected. The multiple bottle valves 130 are connected to the third valves 114 one-to-one via hoses 120, enabling multiple hydrogen storage devices to be connected to the valve array 110 in parallel pipelines. This allows the multiple third valves 114 to simultaneously or separately control the flow of hydrogen, achieving reasonable distribution of hydrogen flow or special control requirements. One end of the pressure reducing valve 140 is connected to the first valve 112 via a pipeline; furthermore, the pressure reducing valve 140 can also replace the first valve 112 and be directly integrated into the hydrogen supply port.

[0040] The heating and cooling circulation device 200 is used to cool or heat the heating and cooling circulation chamber 500 in which the hydrogen storage device is located, thereby improving the efficiency of hydrogen storage and release and ensuring that the temperature remains within a reasonable range during the charging and releasing process. Specifically, the heating and cooling circulation device 200 can be an air-cooled electric heating device, including a compressor 210, a filter, a capillary tube, a condenser, and a condenser fan located outside the heating and cooling circulation chamber 500, and an evaporator, an evaporator fan 220, and a resistance wire 230 located inside the heating and cooling circulation chamber 500. The design of the compressor 210, filter, capillary tube, condenser, evaporator, and evaporator fan 220 is basically the same as that of an air conditioner, and after being powered on, it mainly cools the hydrogen storage device; the specific cooling process will not be described in detail here. The resistance wire 230 is wound around the outer periphery of the hydrogen storage device by a winding frame and can be powered on to generate heat to heat the hydrogen storage device.

[0041] When the hydrogen storage device is being filled with hydrogen, the cooling and heating circulation device 200 starts cooling. The compressor 210, filter, capillary tube, condenser, condenser fan, evaporator, and evaporator fan 220 operate, similar to the principle of air conditioning. The evaporator fan 220 blows cold air into the cooling and heating circulation chamber 500 to create air cooling for the hydrogen storage device. When the hydrogen storage device is releasing hydrogen, heating starts. The resistance wire 230 is energized and heats up, creating electric heating for the hydrogen storage device. Furthermore, to enhance the heating effect, the compressor 210, filter, capillary tube, condenser, condenser fan, evaporator, and evaporator fan 220 can also participate in heating, similar to the principle of air conditioning heating. The evaporator fan 220 blows hot air into the cooling and heating circulation chamber 500 to create air heating for the hydrogen storage device.

[0042] The temperature sensor 300 is installed inside the heating and cooling circulation chamber 500 and is communicatively connected to the heating and cooling circulation device 200 via the control motherboard, for real-time monitoring of the temperature inside the heating and cooling circulation chamber 500. The control motherboard has a pre-set heating temperature threshold T. 热 and cooling temperature threshold T 冷 (T 冷 >T 热 This ensures that the temperature inside the hot and cold circulation chamber 500 remains within the threshold range during the hydrogen charging and discharging process of the hydrogen storage device.

[0043] The pressure sensor 400 is installed in the pipeline of the manifold 100, for example, near the hydrogen charging port of the manifold 100, and is communicatively connected to the hydrogen production device and the hot and cold circulation device 200 through the control motherboard. It is used to monitor the hydrogen pressure in the pipeline in real time to ensure safe system operation. The control motherboard is pre-set with a first preset value P1, a second preset value P2, and the hydrogen pressure value P of the hydrogen-using device. 用And the third preset value P3 (P1>P2, P 用 >P3) to ensure that the hydrogen storage device operates under safe pressure during the charging and discharging processes. For example, during charging, when the pressure sensor 400 detects that the pressure value P in the pipeline reaches the first preset value P1, the control board controls the hydrogen production device to stop working, because higher pressure will damage the hydrogen production device; after the hydrogen storage alloy in the hydrogen storage device absorbs some hydrogen, the pressure slowly decreases, and when the pressure value P drops to the second preset value P2, the hydrogen production device is restarted. Similarly, during discharging, when the pressure sensor 400 detects that the pressure value P in the pipeline drops to the third preset value P3, it indicates that the released hydrogen flow rate is small, meaning that the hydrogen storage alloy in the hydrogen storage device is releasing hydrogen at a slow rate, requiring heating. At this time, the control board controls the heating and cooling circulation device 200 to operate, raising the temperature inside the heating and cooling circulation chamber 500.

[0044] Example 2

[0045] like Figure 3 and Figure 4 As shown, this embodiment provides a hydrogen energy input and output control method for controlling the hydrogen energy input and output control system described in Embodiment 1, including a hydrogen energy input mode, a hydrogen energy output mode, and an idle mode.

[0046] In hydrogen input mode, the control board opens the hydrogen filling port of the manifold 100, activates the hydrogen filling mode of the cylinder valve 130, closes the pressure reducing valve 140, and keeps the temperature sensor 300 and pressure sensor 400 running continuously. The control board also controls the start and stop of the hydrogen production device based on the pressure value P in the pipeline monitored by the pressure sensor 400. Simultaneously, it controls the start and stop of the hot and cold circulation device 200 based on the temperature value T in the hot and cold circulation chamber 500 monitored by the temperature sensor 300 and the pressure value P in the pipeline monitored by the pressure sensor 400. Finally, the hydrogen produced by the hydrogen production device is batch-filled into multiple hydrogen storage devices via the hydrogen filling port of the manifold 100 and the cylinder valve 130.

[0047] Specifically, in hydrogen energy input mode, the control method includes the following steps:

[0048] S11. The main control board controls the opening of the hydrogen filling port of the manifold 100, the bottle valve 130 is activated in hydrogen filling mode, the pressure reducing valve 140 is closed, the temperature sensor 300 and the pressure sensor 400 are always running, the hydrogen production device is started, and the process proceeds to step S12.

[0049] S12. Determine whether P < P1. If yes, the hydrogen production device continues to operate and proceeds to step S13; otherwise, proceed to step S14.

[0050] S13. Determine whether T≥T 冷 If yes, then control the cooling and heating circulation device 200 to start cooling; if no, then control the cooling and heating circulation device 200 to be in a stopped state.

[0051] S14. Control the hydrogen production device to stop and proceed to step S15;

[0052] S15. When P = P2, control the hydrogen production device to restart and proceed to step S12.

[0053] In hydrogen output mode, the control board closes the hydrogen filling port of the manifold 100, activates the hydrogen release mode of the cylinder valve 130, opens the pressure reducing valve 140, and the temperature sensor 300 and pressure sensor 400 operate continuously. Based on the temperature value T monitored by the temperature sensor 300 within the hot and cold circulation chamber 500 and the pressure value P monitored by the pressure sensor 400 in the pipeline, the control board starts and stops the hot and cold circulation device 200. Finally, the hydrogen in the hydrogen storage device flows to the hydrogen consumption device via the cylinder valve 130 and pressure reducing valve 140 of the manifold 100.

[0054] Specifically, in hydrogen energy output mode, the control method includes the following steps:

[0055] S21. The control board controls the hydrogen filling port of the manifold 100 to close, the bottle valve 130 to activate the hydrogen release mode, the pressure reducing valve 140 to open, the temperature sensor 300 and the pressure sensor 400 to run continuously, and then proceeds to step S22.

[0056] S22. Determine whether P > P3. If yes, control the hot and cold circulation device 200 to be in a shutdown state and proceed to step S23; otherwise, proceed to step S24.

[0057] S23. Determine whether T≤T 热 If yes, then control the heating and cooling circulation device 200 to start heating; if no, then control the heating and cooling circulation device 200 to be in a stopped state.

[0058] S24. Control the start of heating of the hot and cold circulation device 200 and proceed to S22.

[0059] Furthermore, in step S23, when T≤T 热 At this time, the control unit 200 for the hot and cold circulation device only activates the resistance wire 230 for heating. When the pressure is sufficient, using only electric heating can ensure that the heating effect can maintain a stable hydrogen release process while maximizing energy savings.

[0060] Furthermore, in step S24, when P≤P3, the entire heating and cooling circulation device 200 is activated for heating. While the resistance wire 230 provides electric heating, the evaporator fan 220 blows hot air into the heating and cooling circulation chamber 500. In cases of insufficient pressure, this simultaneous use of electric and air heating ensures that the heating effect can quickly increase the hydrogen release pressure.

[0061] In the idle mode, the control motherboard controls the hydrogen production device, bottle valve 130, hot and cold circulation device 200, temperature sensor 300 and pressure sensor 400 to be in the off state.

[0062] In summary, this invention provides an advanced hydrogen energy input and output control system and method. This system, by configuring temperature sensors within the hot and cold circulation chambers and installing pressure sensors in the manifold, achieves real-time monitoring of key parameters during the hydrogen energy input and output process of the hydrogen storage device. Specifically, the temperature sensors accurately measure temperature changes within the hot and cold circulation chambers, while the pressure sensors capture pressure fluctuations in the manifold. This real-time collected data is transmitted to the control motherboard, where, through pre-set algorithms and logical judgments, the system automatically adjusts and optimizes the operating status of the hydrogen production unit and the hot and cold circulation unit. When the temperature or pressure exceeds the preset safety range, the system responds rapidly, such as adjusting the power of the heating or cooling system or adjusting the rate of the hydrogen production reaction, to ensure the stable operation of the entire hydrogen energy system. Furthermore, this intelligent control method effectively avoids unnecessary energy loss and improves energy utilization efficiency, thereby achieving the goal of energy conservation and emission reduction.

[0063] Overall, this invention not only ensures the continuity and safety of hydrogen energy supply but also significantly improves the overall performance and economic efficiency of the system. In this way, it not only provides strong support for the development of hydrogen energy technology but also explores a more efficient and environmentally friendly path for future clean energy applications.

[0064] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial applicability. The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
