Description

Technical Field

[0001] The present application relates to the technical field of hydrogen production and storage, and particularly relates to a control method, device, storage medium and hydrogen production and storage system for a hydrogen production and storage system. Background Art

[0002] During the operation of a hydrogen production and storage system, due to the influence of various factors such as the electro-dragging effect and pressure migration, moisture will migrate through the proton exchange membrane to the hydrogen generation side, resulting in a reduction or even damage to the performance of the electrode equipment. Therefore, drainage can be carried out on the hydrogen generation side to ensure the normal operation of the hydrogen production and storage system.

[0003] In the traditional automatic drainage process, water is collected through a water collector and then drained through liquid level detection, resulting in a lag in response, high maintenance costs, and the need to accumulate a certain amount of water before draining. The pressure at the drainage port is low, the drainage process cycle is long, the hydrogen charging pressure accumulates too high, increasing safety hazards such as bursting of the hydrogen charging pipeline, and frequent long-cycle drainage will cause excessive leakage of hydrogen, resulting in too high hydrogen charging energy consumption and affecting the hydrogen charging efficiency.

[0039] Figure 1A schematic flowchart showing a control method for a hydrogen production and storage system according to an embodiment of the present application is shown. As Figure 1 shown, in an embodiment of the present application, a control method for a hydrogen production and storage system is provided, including the following steps:

[0040] Step 101: Obtain in real time the working current of the electrolyzer and the real-time pressure when the hydrogen gas generated on the cathode side of the electrolyzer flows through the hydrogen filling pipeline.

[0041] The hydrogen production and storage system includes an electrolyzer and a hydrogen filling pipeline. Among them, the hydrogen filling pipeline is connected to the electrolyzer. The electrolyzer can be used for hydrogen production and can store the generated hydrogen through the hydrogen filling pipeline. According to the demand, the hydrogen production and storage system can be controlled to operate, and at this time, hydrogen gas starts to be generated on the cathode side of the electrolyzer.

[0042] The hydrogen production and storage system may further include a current sensor and a pressure sensor. The current sensor can be installed at the connection terminals of the positive and negative electrodes of the electrolyzer, or the current sensor can be installed at other positions convenient for collecting the working current of the electrolyzer. The pressure sensor can be installed on the hydrogen filling pipeline, or installed at other positions convenient for collecting the hydrogen pressure on the cathode side of the electrolyzer.

[0043] When the hydrogen production and storage system is operating, the working current of the electrolyzer can be collected through the current sensor, and the real-time pressure of the hydrogen gas on the cathode side of the electrolyzer can be collected through the pressure sensor. After the current sensor and the pressure sensor collect the corresponding data, they can be sent to the processor in real time, and the processor can obtain in real time the working current of the electrolyzer and the real-time pressure when the hydrogen gas generated on the cathode side of the electrolyzer flows through the hydrogen filling pipeline.

[0044] Step 102: Determine the real-time water volume generated on the cathode side of the electrolyzer according to the working current and the real-time pressure.

[0045] During the electrolysis process, water volume will be generated on the cathode of the electrolyzer due to the electroosmotic drag mechanism and the pressure migration mechanism. Therefore, the processor can analyze the water volume generated by the electrolyzer under the electroosmotic drag mechanism according to the working current, and can analyze the water volume generated by the electrolyzer under the pressure migration mechanism according to the real-time pressure, and then determine the real-time water volume generated on the cathode side of the electrolyzer.

[0046] In an embodiment of the present application, determining the real-time water volume generated on the cathode side of the electrolyzer according to the working current and the real-time pressure includes: determining the water volume generated by the electrolyzer under the electroosmotic drag mechanism and the pressure migration mechanism respectively according to the working current and the real-time pressure; obtaining the number of single chambers of the electrolyzer, the operating time, and the effective area of the membrane electrode of the electrolyzer; determining the real-time water volume according to the water volume generated by the electrolyzer under the electroosmotic drag mechanism and the pressure migration mechanism, the number of single chambers, the operating time, and the effective area.

[0047] During the electrolysis process of the electrolytic cell, protons in the sulfonate proton membrane will hydrate with one or more water molecules to form hydrated protons. Driven by the electric field force, the protons migrate from the anode to the cathode, and at the same time, they will drag several water molecules carried from the anode to the cathode together, resulting in the generation of water volume on the cathode side of the electrolytic cell, which is the electroosmotic drag mechanism of the electrolytic cell. The water volume generated under the electroosmotic drag mechanism is proportional to the current of the electrolytic cell. Thus, the processor can determine the water volume generated by the electrolytic cell under the electroosmotic drag mechanism according to the working current of the electrolytic cell.

[0048] In the embodiment of the present application, determining the water volume generated by the electrolytic cell under the electroosmotic drag mechanism according to the working current includes: obtaining a first functional relationship, where the first functional relationship defines the relationship between the electroosmotic drag water volume of the electrolytic cell and the current of the electrolytic cell; based on the first functional relationship, and determining the water volume generated by the electrolytic cell under the electroosmotic drag mechanism according to the working current.

[0049] The processor can obtain a first functional relationship, where the first functional relationship defines the relationship between the electroosmotic drag water volume of the electrolytic cell and the current of the electrolytic cell. The processor can be based on the first functional relationship and determine the water volume generated by the electrolytic cell under the electroosmotic drag mechanism according to the working current.

[0050] Specifically, the electroosmotic drag water volume of the electrolytic cell is in a proportional relationship with the current of the electrolytic cell, and the first functional relationship is defined by formula (1):

[0051]

[0052] where N drag refers to the water volume generated by the electrolytic cell under the electroosmotic drag mechanism, that is, the electroosmotic drag water volume, with the unit of ml / cm2·S, λ refers to the water content of the proton membrane, refers to the electroosmotic drag coefficient of the proton membrane in the water-saturated state, which can be set to 2.5, F refers to the Faraday constant, which can be set to 9.65×104 C / mol, and I refers to the working current of the electrolytic cell, with the unit of A.

[0053] During the electrolysis process of the electrolytic cell, hydrogen and oxygen will be generated at the anode and cathode respectively, and the pressure on the cathode side will be higher than that on the anode side. Therefore, under the push of the pressure gradient, water will flow macroscopically from the cathode side of the membrane to the anode side, which is the pressure migration mechanism of the electrolytic cell. The water volume generated under the pressure migration mechanism is proportional to the pressure of the electrolytic cell. Thus, the processor can determine the water volume generated by the electrolytic cell under the pressure migration mechanism according to the real-time pressure of the electrolytic cell.

[0054] In an embodiment of the present application, determining the amount of water generated by the electrolytic cell under the pressure migration mechanism according to the real-time pressure includes: obtaining the anode-side pressure of the electrolytic cell and a second functional relationship, where the second functional relationship defines the relationship between the pressure migration water volume of the electrolytic cell and the pressure of the electrolytic cell; based on the second functional relationship, and according to the real-time pressure and the anode-side pressure, determining the amount of water generated by the electrolytic cell under the pressure migration mechanism.

[0055] The processor can obtain the anode-side pressure of the electrolytic cell and a second functional relationship, where the second functional relationship defines the relationship between the pressure migration water volume of the electrolytic cell and the pressure of the electrolytic cell. The processor can, based on the second functional relationship, and according to the real-time pressure and the anode-side pressure, determine the amount of water generated by the electrolytic cell under the pressure migration mechanism.

[0056] Specifically, the pressure migration water volume of the electrolytic cell is in a direct proportion relationship with the pressure of the electrolytic cell, and the second functional relationship is defined by formula (2):

[0057]

[0058] Where N pre refers to the amount of water generated by the electrolytic cell under the pressure migration mechanism, that is, the pressure migration water volume, with the unit of ml / cm2·S, c w refers to the water concentration, k p refers to the permeability coefficient of water in the proton membrane, μ refers to the viscosity of water in the proton membrane, p ca refers to the real-time pressure when the hydrogen gas generated on the cathode side of the electrolytic cell flows through the hydrogen charging pipeline, p an refers to the anode-side pressure, that is, the pressure of the oxygen generated on the anode side of the electrolytic cell, σ m refers to the thickness of the proton membrane.

[0059] The processor can obtain the number of single chambers of the electrolytic cell, the operating time, and the effective area of the membrane electrode of the electrolytic cell, and can determine the real-time water volume according to the amount of water generated by the electrolytic cell under the electroosmotic drag mechanism and the pressure migration mechanism, the number of single chambers, the operating time, and the effective area. Specifically, in one embodiment, the real-time water volume generated on the cathode side of the electrolytic cell is determined by the following formula (3):

[0060] N = ∫[(N drag + N pre )·n·S]·dt Formula (3)

[0061] Where N refers to the real-time water volume generated on the cathode side of the electrolytic cell, N drag refers to the amount of water generated by the electrolytic cell under the electroosmotic drag mechanism, N pre refers to the amount of water generated by the electrolytic cell under the pressure migration mechanism, n refers to the number of single chambers of the electrolytic cell, S refers to the effective area of the membrane electrode of the electrolytic cell, and t refers to the operating time of the electrolytic cell.

[0062] Step 103: Control the hydrogen filling and drainage of the hydrogen production and storage system according to the real-time pressure and real-time water volume.

[0063] The processor can determine whether the hydrogen production and storage system can start to execute hydrogen filling and start drainage, so as to realize the control of hydrogen filling and drainage of the hydrogen production and storage system. Specifically, the processor can compare the real-time pressure of the hydrogen on the cathode side of the electrolyzer with the rated hydrogen filling pressure of the hydrogen production and storage system, and can determine whether to start to execute hydrogen filling and start drainage according to the comparison result.

[0064] In the embodiment of the present application, if the real-time pressure is greater than or equal to the rated hydrogen filling pressure, it means that the pressure of the hydrogen in the hydrogen filling pipeline reaches the rated hydrogen filling pressure at this time. At this time, hydrogen filling can be started and drainage is not started to ensure that the hydrogen generated by the electrolyzer is filled into the hydrogen storage device connected to the hydrogen filling pipeline at the rated hydrogen filling pressure. If the real-time pressure is less than the rated hydrogen filling pressure, it means that the pressure of the hydrogen in the hydrogen filling pipeline has not reached the rated hydrogen filling pressure at this time. At this time, hydrogen filling is not started and drainage is not started.

[0065] During the hydrogen filling process, the processor can combine the real-time water volume generated on the cathode side of the electrolyzer to control the hydrogen filling and drainage of the hydrogen production and storage system. For example, it can control the hydrogen production and storage system to continue to execute hydrogen filling and not start drainage, can control the hydrogen production and storage system to stop hydrogen filling and not start drainage, can control the hydrogen production and storage system to stop hydrogen filling and start drainage, etc.

[0066] In the embodiment of the present application, when the following conditions are met, control the hydrogen production and storage system to execute hydrogen filling and not start drainage: the real-time pressure is greater than the minimum hydrogen filling pressure of the hydrogen production and storage system and the real-time water volume is less than or equal to a preset multiple of the rated water capacity, and the rated hydrogen filling pressure is greater than the minimum hydrogen filling pressure.

[0067] During the hydrogen filling process, if the real-time pressure of the hydrogen on the cathode side of the electrolyzer is greater than the minimum hydrogen filling pressure of the hydrogen production and storage system, and the real-time water volume is less than or equal to a preset multiple of the rated water capacity, it means that the real-time pressure of the hydrogen in the hydrogen filling pipeline meets the hydrogen filling requirements and the water volume generated on the cathode side of the electrolyzer has not reached the set drainage volume. The water volume generated on the cathode side of the electrolyzer is within an appropriate range, and the hydrogen production and storage system can operate normally. The processor can continue to execute hydrogen filling and not start drainage.

[0068] Among them, the preset multiple can be set according to actual needs. For example, the preset multiple can be set to 0.8. The rated hydrogen filling pressure is greater than the minimum hydrogen filling pressure. The rated hydrogen filling pressure and the minimum hydrogen filling pressure can be determined according to the parameters of the hydrogen production and storage system and the parameters of the equipment on the side to be hydrogen-filled. The parameters of the hydrogen production and storage system include safety pressure, hydrogen production capacity, and working environment conditions, etc. The parameters of the equipment on the side to be hydrogen-filled include the hydrogen storage working pressure, safety parameters, and working environment conditions corresponding to the hydrogen storage medium, etc.

[0069] In the embodiment of the present application, when any of the following conditions is met, the hydrogen production and storage system is controlled to stop hydrogen charging and not start draining: the real-time pressure is less than or equal to the minimum hydrogen charging pressure of the hydrogen production and storage system and the real-time water volume is less than or equal to a preset multiple of the rated water capacity; the real-time pressure is less than the rated draining pressure of the hydrogen production and storage system, and the real-time water volume is greater than or equal to a preset multiple of the rated water capacity and less than or equal to the rated water capacity, where the rated draining pressure is greater than the minimum hydrogen charging pressure.

[0070] If the real-time pressure is less than or equal to the minimum hydrogen charging pressure of the hydrogen production and storage system and the real-time water volume is less than or equal to a preset multiple of the rated water capacity, it indicates that the real-time pressure of the hydrogen in the hydrogen charging pipeline has not reached the draining pressure and the water volume generated on the cathode side of the electrolyzer has not reached the set drainage volume. At this time, the hydrogen production and storage system can be controlled to stop hydrogen charging and not start draining to build pressure in the hydrogen charging pipeline, increase the pressure of the hydrogen in the hydrogen charging pipeline, and ensure that the hydrogen generated by the subsequent electrolyzer can be filled into the hydrogen storage device connected to the hydrogen charging pipeline at the set pressure.

[0071] If the real-time pressure is less than the rated draining pressure of the hydrogen production and storage system, and the real-time water volume is greater than or equal to a preset multiple of the rated water capacity and less than or equal to the rated water capacity, it indicates that the real-time pressure of the hydrogen in the hydrogen charging pipeline has not reached the draining pressure and the water volume generated on the cathode side of the electrolyzer has reached the set drainage volume. At this time, due to the low draining pressure, if draining is carried out, it may take too long and the leakage of hydrogen in the hydrogen pipeline is relatively large. Therefore, the hydrogen production and storage system can be controlled to stop hydrogen charging and not start draining to build pressure in the hydrogen charging pipeline and increase the pressure of the hydrogen in the hydrogen charging pipeline.

[0072] Among them, the rated draining pressure is greater than the minimum hydrogen charging pressure, and the rated draining pressure can be determined according to the parameters of the hydrogen production system and the ambient pressure. The parameters of the hydrogen production system include the safety pressure, hydrogen production capacity, and working environmental conditions, etc.

[0073] In the embodiment of the present application, when any of the following conditions is met, the hydrogen production and storage system is controlled to stop hydrogen charging and start draining: the real-time pressure is greater than or equal to the rated draining pressure of the hydrogen production and storage system, and the real-time water volume is greater than or equal to a preset multiple of the rated water capacity and less than or equal to the rated water capacity; the real-time water volume is greater than or equal to the rated water capacity.

[0074] If the real-time pressure is greater than or equal to the rated drainage pressure of the hydrogen production and storage system, and the real-time water volume is greater than or equal to a preset multiple of the rated water capacity and less than or equal to the rated water capacity, it indicates that the pressure of the hydrogen in the hydrogen filling pipeline has reached the drainage pressure and the water volume generated on the cathode side of the electrolyzer has reached the set drainage volume. At this time, the hydrogen production and storage system can be controlled to stop hydrogen filling and start drainage to achieve high-pressure drainage and reduce the leakage of hydrogen in the hydrogen filling pipeline.

[0075] If the real-time water volume is greater than or equal to the rated water capacity, it indicates that the water volume generated on the cathode side of the electrolyzer has reached the rated water storage capacity, that is, the water volume generated on the cathode side of the electrolyzer may affect the normal operation of the hydrogen production and storage system. At this time, the processor can control the hydrogen production and storage system to stop hydrogen filling and start drainage to ensure the normal operation of the hydrogen production and storage system.

[0076] In the embodiment of the present application, after the hydrogen production and storage system completes the drainage operation, the hydrogen production and storage system can be controlled to continue hydrogen filling and not start drainage to achieve intermittent hydrogen filling of the hydrogen production and storage system and improve the hydrogen filling efficiency.

[0077] In the embodiment of the present application, if the real-time pressure of the hydrogen generated on the cathode side of the electrolyzer is less than or equal to the minimum hydrogen filling pressure of the hydrogen production and storage system, it indicates that the hydrogen filling requirement is not met. The hydrogen production and storage system can be controlled not to perform hydrogen filling and not start drainage. If hydrogen filling has been performed, stop performing hydrogen filling. If hydrogen filling has not been performed, keep not performing hydrogen filling.

[0078] For example, if the real-time pressure after the hydrogen production and storage system completes the drainage operation and then continues to perform hydrogen filling is less than or equal to the minimum hydrogen filling pressure, hydrogen filling can be stopped. If the real-time pressure when the hydrogen production and storage system completes the drainage operation but has not continued to perform hydrogen filling is less than or equal to the minimum hydrogen filling pressure, keep not filling hydrogen.

[0079] In the embodiment of the present application, a hydrogen filling control valve is installed on the hydrogen filling pipeline, and the hydrogen production and storage system further includes a drainage control valve. The control method further includes: controlling the opening or closing of the hydrogen filling control valve to respectively control the hydrogen production and storage system to start or stop hydrogen filling; controlling the opening or closing of the drainage control valve to respectively control the hydrogen production and storage system to start or not start drainage.

[0080] A hydrogen filling control valve is installed on the hydrogen filling pipeline. The hydrogen filling control valve is used to control the filling of hydrogen. The hydrogen production and storage system further includes a drainage control valve. The drainage control valve is used to control the discharge of the water volume generated on the cathode side of the electrolyzer. The processor can control the hydrogen filling control valve to open to control the hydrogen production and storage system to start hydrogen filling, and can control the hydrogen filling control valve to close to control the hydrogen production and storage system to stop hydrogen filling. The processor can control the drainage control valve to open to control the hydrogen production and storage system to start drainage, and can control the drainage control valve to close to control the hydrogen production and storage system not to start drainage.

[0081] For example, when the real-time pressure is greater than or equal to the rated hydrogen charging pressure of the hydrogen production and storage system, it is necessary to control the hydrogen production and storage system to perform hydrogen charging and not start draining water. Then, the hydrogen charging control valve can be controlled to open and the drain control valve can be controlled to close. Another example is that when the real-time pressure is less than or equal to the minimum hydrogen charging pressure of the hydrogen production and storage system and the real-time water volume is less than or equal to the rated water capacity of the preset multiple, it is necessary to control the hydrogen production and storage system to stop hydrogen charging and not start draining water. Then, the hydrogen charging control valve can be controlled to close and the drain control valve can be controlled to close.

[0082] In this way, the hydrogen charging and draining can be flexibly controlled through the hydrogen charging control valve and the drain control valve. In this embodiment, the opening and closing of the hydrogen charging control valve and the drain control valve can be set according to the control schemes in the above different situations, which will not be elaborated here.

[0083] Through the above technical solutions, the working current of the electrolyzer and the real-time pressure when the hydrogen gas generated on the cathode side of the electrolyzer flows through the hydrogen charging pipeline are obtained in real time; the real-time water volume generated on the cathode side of the electrolyzer is determined according to the working current and the real-time pressure; the hydrogen production and storage system is controlled for hydrogen charging and draining according to the real-time pressure and the real-time water volume, realizing intermittent draining and high-pressure hydrogen charging, effectively increasing the pressure of the draining operation and making the single hydrogen charging pressure more stable, shortening the single draining time and the single hydrogen charging time, reducing the hydrogen leakage amount, and effectively improving the hydrogen charging efficiency.

The hydrogen filling pipeline is the pipeline where the gas-liquid separation module, hydrogen purification module, and hydrogen filling port are located, and a pressure sensor (pressure acquisition instrument in the figure) is installed thereon. The pressure sensor is used to collect the real-time pressure of the hydrogen filling pipeline.

[0094] The hydrogen filling control valve is installed on the pipeline at the front end of the hydrogen filling port for controlling hydrogen filling. The drain control valve (automatic drain valve in the figure), connected to the electrolyzer, is specifically installed on the pipeline at the front end of the drain port for controlling the discharge of the water generated on the cathode side of the electrolyzer.

[0095] The control device for the hydrogen production and storage system includes the data processing unit, data acquisition unit, and control unit shown in the figure. The data acquisition unit transmits the current and pressure signals collected by the current acquisition instrument and pressure acquisition instrument to the data processing unit. The data processing unit analyzes and processes the current and pressure signals based on the water diffusion mechanism in the electrolyzer to generate a control instruction signal, and issues the control instruction signal to the automatic drain valve and hydrogen filling control valve to complete the intermittent drainage and hydrogen filling operations.

[0096] As Figure 3 shown, taking the hydrogen production and storage system described above Figure 2 as an example, a schematic flow diagram of another control method for the hydrogen production and storage system is provided.

[0097] The hydrogen production system starts to run. The automatic drain valve ① and the hydrogen filling control valve ② are closed. The current acquisition instrument installed at the hydrogen production system and the pressure acquisition instrument installed at the hydrogen filling port monitor in real time and output the system current I and pressure P signals to the data acquisition unit, and then write them into the data processing unit. The data processing unit automatically calculates the amount of water N generated on the cathode side based on the water diffusion mechanism in the electrolyzer according to the real-time collected current I and pressure P.

[0098] The data processing unit makes a judgment based on the real-time water volume N and pressure P. When the pressure P < the rated hydrogen charging pressure P A , it indicates that the hydrogen pressure in the hydrogen charging pipeline has not reached the set rated hydrogen charging pressure. The closed states of the automatic drain valve ① and the hydrogen charging control valve ② are maintained, and it returns to the step of real-time monitoring and outputting the system current I and pressure P signals. When the pressure P ≥ the rated hydrogen charging pressure P A , it indicates that the hydrogen pressure in the hydrogen charging pipeline has reached the set rated hydrogen charging pressure. The hydrogen charging control valve ② is opened, the closed state of the automatic drain valve ① is maintained, and the hydrogen charging operation is performed to ensure that hydrogen is charged into the hydrogen storage device at the set pressure.

[0099] During the hydrogen charging process, the data processing unit judges whether to perform the operation of stopping hydrogen charging or draining water based on the real-time water volume N and pressure P, ensuring that during the operation, the water volume is controlled within an appropriate range to avoid system failures caused by excessive water volume.

[0100] When the pressure P > the minimum hydrogen charging pressure P B and the water volume N ≤ 0.8N rated, it indicates that the hydrogen pressure in the pipeline meets the hydrogen charging requirements and the accumulated water volume in the gas-liquid separation module has not reached the set drainage volume. Continue hydrogen charging, maintain the closed state of the automatic drain valve ① and the open state of the hydrogen charging control valve ②, and return to the step of judging whether to perform the operation of stopping hydrogen charging or draining water based on the real-time water volume N and pressure P.

[0101] When the pressure P ≤ the minimum hydrogen charging pressure P B and the water volume N ≤ 0.8N rated, it indicates that the hydrogen pressure in the pipeline has not reached the drainage pressure and the accumulated water volume in the gas-liquid separation module has not reached the set drainage volume. Hydrogen charging can be continued after pressure buildup. The hydrogen charging control valve ② is closed, the closed state of the automatic drain valve ① is maintained, and hydrogen charging is stopped.

[0102] When the pressure P < the rated drainage pressure P C and the water volume 0.8N rated ≤ N ≤ N rated, it indicates that the hydrogen pressure in the pipeline has not reached the drainage pressure and the accumulated water volume in the gas-liquid separation module has reached the set drainage volume. The hydrogen charging control valve ② is closed, the closed state of the automatic drain valve ① is maintained, and hydrogen charging is stopped.

[0103] When the pressure P ≥ the rated drainage pressure P C and the water volume 0.8N rated ≤ N ≤ N rated, it indicates that the hydrogen pressure in the pipeline has reached the drainage pressure and the accumulated water volume in the gas-liquid separation module has reached the set drainage volume. The hydrogen charging control valve ② is closed, the automatic drain valve ① is opened, hydrogen charging is stopped, and the drainage operation is performed to achieve high-pressure drainage and reduce hydrogen leakage.

[0104] When the water volume N ≥ the rated water capacity (N rated) in the gas-liquid separation module, it indicates that the accumulated water volume in the gas-liquid separation module has reached the rated water storage capacity. Close the hydrogen charging control valve ②, open the automatic drain valve ①, stop hydrogen charging, and perform the drainage operation.

[0105] After the system completes the drainage operation, close the automatic drain valve ①, open the hydrogen charging control valve ②, and perform the hydrogen charging operation. When the pressure P ≤ the minimum hydrogen charging pressure P B , close the hydrogen charging control valve ②, maintain the closed state of the automatic drain valve ①, and return to the step of real-time monitoring and outputting the system current I and pressure P signals.

[0106] The above technical solution does not require the additional installation of a water collector and a liquid level sensor. It determines the water volume generated on the cathode side of the electrolytic cell based on the working current and real-time pressure collected by the sensor, thereby realizing intermittent quantitative drainage control and high-pressure hydrogen charging control, effectively increasing the pressure of the drainage operation and making the single hydrogen charging pressure more stable, shortening the single drainage time and single hydrogen charging time, reducing the hydrogen leakage amount, and effectively improving the hydrogen charging efficiency.
