[0002] With the rapid breakthroughs in new energy technologies and the rapid development of the low-carbon economy, various new energy products are emerging in an endless stream. Solid-state hydrogen storage technology, as a safe, stable, and efficient energy storage method, plays an important role in new energy technologies. However, existing solid-state hydrogen storage technologies are not well controlled in terms of hydrogen charging and discharging. Furthermore, due to the large amount of heat exchange involved in the hydrogen charging and discharging process, it is difficult to achieve efficient hydrogen charging and reliable hydrogen discharging, ultimately leading to problems such as low charging and discharging efficiency, frequent and complicated operation, and insufficient safety of hydrogen storage devices. Summary of the Invention

[0003] The purpose of this invention is to provide a control system for a solid hydrogen storage device to control the hydrogen charging and discharging process, thereby improving the hydrogen charging and discharging efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention includes: A control system for a solid-state hydrogen storage device includes: Hydrogen storage containers; A hydrogen quantity monitoring module includes a flow meter installed in the hydrogen filling and / or hydrogen discharging pipeline, which accumulates the amount of hydrogen during the hydrogen filling and / or hydrogen discharging process and controls the start and stop of the hydrogen filling and / or hydrogen discharging process. A pressure monitoring and regulation module includes a pressure sensor and a pressure regulator installed in the hydrogen charging and / or hydrogen discharging pipeline. The pressure sensor is used to monitor the pressure of hydrogen charging and / or hydrogen discharging, and the pressure regulator is used to adjust the pressure of the hydrogen charging and / or hydrogen discharging process according to the pressure monitored by the pressure sensor. The thermal management module includes a heat exchange device connected to the hydrogen storage container and a temperature sensor, the temperature sensor being used to measure the temperature of the hydrogen storage container and control the temperature of the heat exchange device accordingly.

[0005] In one embodiment, there are multiple hydrogen storage containers, and the heat exchange device includes a heating circulating water pipe connected in series with each of the hydrogen storage containers. Along the water flow direction of the heating circulating water pipe, the hydrogen storage containers are defined sequentially as the first, second...Nth hydrogen storage container, where N is the number of hydrogen storage containers. At least one temperature sensor is used to detect the temperature of the Nth hydrogen storage container, and the water temperature in the heating circulating water pipe is adjusted based on the temperature of the Nth hydrogen storage container or based on the temperature of the Nth hydrogen storage container and the hydrogen release pressure.

[0006] In one embodiment, the heat exchange device includes heating pipes and cooling pipes. The heating pipes are used to heat the hydrogen storage container to assist in its hydrogen release, and the cooling pipes are used to cool the hydrogen storage container to assist in its hydrogen filling. The heating pipes include a heat exchanger and a heater. The heat exchanger is connected to the hydrogen fuel cell and uses the operating temperature of the hydrogen fuel cell to raise the water temperature in the heating circulating water pipe. The heater is used to heat the water in the heating circulating water pipe when the water temperature is lower than a preset value. The cooling pipes include cooling circulating water pipes connected in series with each of the hydrogen storage containers.

[0007] In one embodiment, the hydrogen quantity monitoring module is connected to the control panel. During the hydrogen charging process, the control panel receives the real-time flow rate monitored by the flow meter, accumulates the real-time flow rate to obtain the actual hydrogen charging amount, compares the actual hydrogen charging amount with the theoretical total hydrogen storage capacity of the hydrogen storage container, and stops the hydrogen charging process if the difference between the actual hydrogen charging amount and the theoretical total hydrogen storage capacity is within a preset range. During the hydrogen release process, the control panel receives the real-time flow rate monitored by the flow meter, accumulates the real-time flow rate to obtain the actual hydrogen release amount, and calculates the difference between the theoretical total hydrogen storage capacity of the hydrogen storage container and the actual hydrogen release amount to obtain the hydrogen reserve. If the hydrogen reserve reaches the preset value range, the hydrogen release process is stopped.

[0008] In one embodiment, there are multiple hydrogen storage containers connected to a hydrogen filling main pipe and a hydrogen discharging main pipe, and the flow meter includes a hydrogen filling flow meter disposed on the hydrogen filling main pipe and a hydrogen discharging flow meter disposed on the hydrogen discharging main pipe.

[0009] In one embodiment, there are multiple hydrogen storage containers, each of which is connected to a pressure sensor. The multiple hydrogen storage containers are connected to a hydrogen consumption device through a hydrogen release manifold. The hydrogen release manifold is equipped with the pressure sensor, a pressure regulator, and a hydrogen release flow meter. The pressure regulator is used to adjust the hydrogen release pressure of the hydrogen release manifold in a stepwise manner until a preset hydrogen release pressure is reached. The pressure difference of this stepwise adjustment corresponds to the pressure difference of the hydrogen release flow meter.

[0010] In one embodiment, there are multiple hydrogen storage containers, each of which is connected to a pressure sensor. The multiple hydrogen storage containers are connected to a hydrogen supply device through a hydrogen filling manifold. The hydrogen filling manifold is equipped with the pressure sensor, a pressure regulator, and a hydrogen filling flow meter. The pressure regulator is used to adjust the hydrogen filling pressure of the hydrogen filling manifold in a stepwise manner until a preset hydrogen filling pressure is reached. The pressure difference of this stepwise adjustment corresponds to the pressure difference of the hydrogen filling flow meter.

[0011] In one embodiment, a safety monitoring module is also included, which includes a hydrogen detector and multiple pressure sensors installed in the hydrogen pipeline. The hydrogen detector is used to monitor the amount of hydrogen leakage in the solid hydrogen storage device. When the amount of hydrogen leakage reaches a threshold or the pressure of any of the pressure sensors reaches a threshold, both the hydrogen filling and releasing processes are stopped.

[0012] In one embodiment, a control panel is also included, which is used to display the hydrogen flow rate, hydrogen quantity, pressure, and temperature of the hydrogen storage container during charging / discharging, and is also used to manually control the start and stop of the hydrogen charging and / or discharging process.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] SeeFigures 1 to 6 As shown, this invention discloses a control system for a solid-state hydrogen storage device. The solid-state hydrogen storage device has three hydrogen storage containers 1. The control system includes a hydrogen quantity monitoring module, a pressure monitoring and regulation module, a thermal management module, a safety monitoring module, and a control panel 2. The control panel 2 displays relevant parameters of the control system, and the user can manually control these parameters through the control panel. The following describes each functional module in detail: See Figure 1 and Figure 2 As shown, all three hydrogen storage containers 1 are connected to the hydrogen charging main pipe 51 and the hydrogen discharging main pipe 52. During the hydrogen charging process, the hydrogen supply device charges the hydrogen storage container 1 with hydrogen through the hydrogen charging main pipe 51. During the hydrogen discharging process, the hydrogen storage container 1 supplies hydrogen to the hydrogen-using device through the hydrogen discharging main pipe. The hydrogen-using device in this embodiment is a hydrogen fuel cell FC, but it is not limited to this.

[0022] The hydrogen charging main pipe 51 is equipped with a hydrogen charging flow meter 31 to collect the real-time flow rate during the hydrogen charging process. The hydrogen charging flow meter 31 is connected to the control panel 2. During the hydrogen charging process, the control panel 2 receives the real-time flow rate monitored by the hydrogen charging flow meter 31. It can also obtain the actual hydrogen charging amount (i.e., hydrogen volume) by accumulating the real-time flow rate multiple times during the continuous hydrogen charging process. The actual hydrogen charging amount is compared with the theoretical total hydrogen storage capacity of the hydrogen storage container 1. If the difference between the actual hydrogen charging amount and the theoretical total hydrogen storage capacity is within a preset range, the hydrogen charging process is stopped. More specifically, if the actual hydrogen charging amount equals the theoretical total hydrogen storage capacity, the hydrogen charging process is stopped. The theoretical total hydrogen storage capacity is also the total hydrogen volume of the solid hydrogen storage device.

[0023] See Figure 1 and Figure 3 As shown, the hydrogen release main pipe 52 is equipped with a hydrogen release flow meter 32 to collect the real-time flow rate during the hydrogen release process. The hydrogen release flow meter 32 is connected to the control panel 2. During the hydrogen release process, the control panel 2 receives the real-time flow rate monitored by the hydrogen release flow meter 32, accumulates the real-time flow rate to obtain the actual hydrogen release amount (i.e., hydrogen volume), and calculates the difference between the theoretical total hydrogen storage capacity of the hydrogen storage container and the actual hydrogen release amount to obtain the hydrogen reserve. If the hydrogen reserve reaches the preset value range, the hydrogen release process is stopped.

[0024] In this embodiment, the hydrogen charging flow meter 31 and the hydrogen discharging flow meter 32 are collectively referred to as flow meters. The total hydrogen storage, the remaining hydrogen volume, and the real-time flow rate during the charging and discharging processes are all displayed on the control panel, allowing users to promptly obtain information about the status of the solid hydrogen storage device. The hydrogen volume refers to the actual amount of hydrogen charged / discharged through the flow meters during the charging / discharging process. In a complete charging process, the hydrogen volume refers to the actual amount of hydrogen charged through the real-time flow rate; in a complete discharging process, the hydrogen volume refers to the actual amount of hydrogen discharged through the real-time flow rate.

[0025] The thermal management module includes a heat exchange device connected to the hydrogen storage container 1 and a temperature sensor. The temperature sensor measures the temperature of the hydrogen storage container and controls the temperature of the heat exchange device accordingly. The heat exchange device includes heating pipes and cooling pipes. The heating pipes are used to heat the hydrogen storage container to assist in its hydrogen release, and the cooling pipes are used to cool the hydrogen storage container to assist in its hydrogen filling.

[0026] See Figure 1 and Figure 4 As shown, the heating pipeline includes a heating circulating water pipe 41 connected in series with each hydrogen storage container, a heat exchanger 44, and a heater 43. The heat exchanger 44 is connected to the hydrogen fuel cell FC and uses the operating temperature of the hydrogen fuel cell FC to raise the water temperature in the heating circulating water pipe 41. The heater 43 is used to heat the water in the heating circulating water pipe 41 when the water temperature is lower than a preset value. Along the water flow direction of the heating circulating water pipe 41, the hydrogen storage containers are defined sequentially as the first, second, ..., Nth hydrogen storage container, where N is the number of hydrogen storage containers. At least one temperature sensor is used to detect the temperature of the Nth hydrogen storage container and adjust the water temperature in the heating circulating water pipe 41 according to the temperature of the Nth hydrogen storage container. Since there are three hydrogen storage containers 1 in this embodiment, the three hydrogen storage containers 1 along the water flow direction of the heating circulating water pipe 41 are the first hydrogen storage container 101, the second hydrogen storage container 102, and the third hydrogen storage container 103, respectively. The first hydrogen storage container 101 is equipped with a first temperature sensor 401, the second hydrogen storage container 102 is equipped with a second temperature sensor 402, and the third hydrogen storage container 103 is equipped with a third temperature sensor 403. Since the solid-state device absorbs heat during hydrogen release, the water temperature in the heating circulating water pipe 41 gradually decreases as it flows sequentially through the first, second, and third hydrogen storage containers 101 and 103. The temperature measured by the third temperature sensor 403 is the lowest. In this embodiment, the temperature measured by the third temperature sensor 403 is used as the standard to adjust the water temperature in the heating circulating water pipe 41; that is, the lowest temperature is used as the standard to determine whether heating is needed, resulting in more reasonable control and reduced data processing. Specifically, in this embodiment, the heater operates when the temperature measured by the third temperature sensor 403 is below 50°C.

[0027] The cooling pipeline includes cooling circulating water pipes 42 connected in series to each hydrogen storage container 1. The cooling circulating water pipes 42 are connected to a room temperature water tank, and a water pump sequentially supplies room temperature water to each hydrogen storage container 1 to cool down the hydrogen charging process and prevent the temperature from getting too high. A first temperature sensor 401, a second temperature sensor 402, and a third temperature sensor 403 detect the temperature of each hydrogen storage container 1. If the temperature is found to be too high, the hydrogen charging process is stopped because excessively high temperatures will reduce the hydrogen charging efficiency.

[0028] The heating circulating water pipe 41 and the cooling circulating water pipe 42 partially overlap to simplify the piping between the various hydrogen storage containers 1. The hydrogen charging and discharging processes are carried out separately, and the overlapping portion of the heating circulating water pipe 41 and the cooling circulating water pipe 42 is supplied with warm and hot water respectively according to the hydrogen charging and discharging processes. This allows for a simple piping layout while ensuring the normal thermal management of the solid-state hydrogen storage device.

[0029] See Figure 1 and Figure 5 As shown, the three hydrogen storage containers 1 are connected to the hydrogen supply device (not shown in the figure) via a hydrogen filling manifold 51, and are also connected to the hydrogen fuel cell FC via a hydrogen discharging manifold 52.

[0030] The hydrogen filling main pipe 51 is equipped with a pressure sensor PT5, a hydrogen filling pressure regulator 61, and a hydrogen release flow meter 32. The hydrogen filling pressure regulator 61 is used to adjust the hydrogen filling pressure of the hydrogen filling main pipe 51 in a stepwise manner until a preset hydrogen filling pressure is reached. The pressure difference of this stepwise adjustment corresponds to the pressure difference of the hydrogen filling flow meter 31. In this embodiment, the preset hydrogen filling pressure is the rated hydrogen storage pressure of the hydrogen storage container 1, specifically 4 MPa. The pressure difference of the stepwise adjustment is equal to the pressure difference of the hydrogen filling flow meter 31, specifically 0.4 MPa, so that the pressure of the hydrogen filling main pipe 51 gradually increases in units of 0.4 MPa. More specifically: During hydrogen charging, the hydrogen charging pressure regulator 61 adjusts the pressure to 0.4 MPa entering the hydrogen charging flow meter 31. When the pressure sensor PT5 detects that the pressure has reached 0.4 MPa, it transmits the signal to the control panel. The control panel performs logic calculations and transmits the signal to the hydrogen charging pressure regulator 61, which increases the pressure in steps to 0.8 MPa, and so on until the pressure sensor PT5 detects that the hydrogen charging pressure has reached 4 MPa.

[0031] The hydrogen release manifold 52 is equipped with two pressure sensors PT4 and PT6, a hydrogen release pressure regulator 62, and a hydrogen release flow meter 32. The hydrogen release pressure regulator 62 is used to adjust the hydrogen release pressure of the hydrogen release manifold 52 in a stepwise manner until a preset hydrogen release pressure is reached. The pressure difference of this stepwise adjustment corresponds to the pressure difference of the hydrogen release flow meter 32. In this embodiment, the preset hydrogen release pressure is the hydrogen consumption pressure of the hydrogen-using device, i.e., the hydrogen fuel cell FC, specifically 1 MPa. The pressure difference of the stepwise adjustment is equal to the pressure difference of the hydrogen release flow meter 32, specifically 0.4 MPa, so that the pressure of the hydrogen release manifold 52 gradually increases in units of 0.4 MPa. More specifically: During hydrogen release, the hydrogen release pressure regulator 62 allows hydrogen gas to enter the hydrogen release flow meter 32 at a pressure of 0.4 MPa. When pressure sensors PT4 and PT6 detect that the pressure has reached 0.4 MPa, they transmit a signal to the control panel. The control panel, after logic calculation, transmits the signal back to the hydrogen release pressure regulator 62, increasing the pressure in stages to 0.8 MPa, and so on, until pressure sensor PT6 detects that the hydrogen release pressure has reached 1 MPa. This stepped pressure regulation protects the stability of the hydrogen charging and releasing system and protects the flow meter. In this embodiment, the design value for the pressure difference between the charging and releasing flow meters is 0.4 MPa. Therefore, 0.4 MPa or lower can be selected; pressures higher than 0.4 MPa will damage the flow meter.

[0032] Hydrogen filling pressure regulator 61 and hydrogen discharging pressure regulator 62 are collectively referred to as pressure regulators.

[0033] In addition, each hydrogen storage container 1 is connected to a pressure sensor, a solenoid valve, a filter, and a check valve. The corresponding pressure sensors (PT1 to PT3) are used to measure the pressure of the hydrogen storage container 1, and the solenoid valve closes the hydrogen filling / discharging pipeline of the hydrogen storage container when the pressure of the hydrogen storage container 1 is abnormal.

[0034] The solid hydrogen storage device of the present invention has multiple hydrogen storage containers 1. The charging / discharging of each hydrogen storage container 1 is connected to the main pipe (hydrogen charging main pipe 51 and hydrogen discharging main pipe 52) through branch pipes. This allows for unified control of the charging / discharging of multiple hydrogen storage containers through the main pipe, improving control efficiency. It also allows for precise control of the corresponding hydrogen storage container 1 through the branch pipes between each hydrogen storage container 1 and the main pipe, improving control accuracy.

[0035] See Figure 4As shown, when the heater 43 of the thermal management module heats the water to a temperature higher than or equal to 50°C, and the hydrogen release pressure regulator 62 raises the pressure of the hydrogen release main pipe 52 to 1 MPa (i.e., the pressure required by the hydrogen-using device), but the pressure of the hydrogen release main pipe 52 is excessively lower than the pressure required by the hydrogen-using device (set to 0.7 MPa in this embodiment), that is, the pressure cannot rise. At this time, there may be insufficient heat, which will affect the hydrogen release. Therefore, the heater 43 continues to heat until the pressure of the hydrogen release main pipe 52 reaches 0.7 MPa or close to the pressure required by the hydrogen-using device, thereby realizing the joint control of the heating of the thermal management module by temperature and pressure.

[0036] See Figure 6 As shown, the safety monitoring module includes a hydrogen detector 7 and multiple pressure sensors (PT1 to PT6) installed in the hydrogen pipeline. The hydrogen detector 7 is used to monitor the amount of hydrogen leakage in the solid hydrogen storage device. When the amount of hydrogen leakage reaches the threshold (3000ppm) or the pressure of any pressure sensor reaches the threshold (6MPa), both the hydrogen filling and releasing processes will stop.

[0037] This invention controls the start and stop of the hydrogen charging and discharging processes by using real-time flow rate, cumulative hydrogen volume (real-time charging and discharging), total hydrogen volume, and remaining hydrogen volume. During the charging / discharging process, parameters such as temperature and pressure of the hydrogen storage container are monitored. If the temperature is too low during discharging, the water is heated to provide the necessary heat. If the temperature is too high, it indicates a possible malfunction in the solid hydrogen storage device's control system, triggering a fault warning. If the flow rate is too low, it means the charging / discharging process may be nearing its end (e.g., the storage container is almost full or the remaining hydrogen volume is low). In this case, parameters such as total hydrogen volume, cumulative hydrogen volume, and remaining hydrogen volume can be used to assist in the judgment. This makes the charging and discharging processes of the solid hydrogen storage device more efficient and intelligent. Furthermore, a safety monitoring module can shut down the hydrogen pipeline in a timely manner to stop the charging / discharging process based on hydrogen leakage and charging / discharging pressure, preventing further hydrogen leakage and improving the safety of the solid hydrogen storage device.

[0038] In the above embodiment, there are three hydrogen storage containers 1. In other embodiments, the number of hydrogen storage containers 1 can also be other, such as one, two, four or more.

[0039] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the invention without departing from the spirit and scope of the invention as defined in the appended claims fall within the protection scope of the invention.
