Description

Technical Field

[0002] An energy storage system refers to a system used to store energy and release it when needed. They play an important role in modern energy systems, especially in improving the utilization rate of renewable energy, enhancing grid stability, and achieving efficient energy management. The safety issue of energy storage systems is particularly important.

[0003] Currently, in order to achieve faster heat dissipation effects, energy storage systems usually adopt a liquid cooling method. When the liquid cooling unit box is operating normally, it will generate condensed water, which is likely to affect the equipment of the liquid cooling unit box, causing damage and failure of electronic components and battery cells. To address this flaw, a liquid cooling unit box with a higher protection level will be adopted. However, when a certain battery cell undergoes thermal runaway, the battery cell generates a large amount of combustible gas. The liquid cooling unit box with a high protection level cannot discharge the gas in time, and it is difficult for the combustible gas detector to detect it, resulting in the thermal runaway of the battery cell developing into thermal diffusion, which may lead to a fire.

The embodiments of the present application do not make specific limitations in this regard. In addition, an explosion-proof valve provided in the embodiments of the present application is only an example, and the explosion-proof valve may also include more or less content.

[0045] To facilitate a clear description of the technical solutions of the embodiments of the present application, the following briefly introduces some terms and technologies involved in the embodiments of the present application:

[0046] Energy storage system: An energy storage system is a system that can store energy and release it when needed. It plays an important role in energy management, power supply stability, and the utilization of renewable energy. Energy storage technology can convert electrical energy into other forms of energy for storage and then convert it back into electrical energy when needed.

[0047] Liquid cooling unit box: A liquid cooling unit box is a device that uses liquid cooling technology to manage the heat of a device or system. The liquid cooling unit box is composed of a battery module, a liquid cooling plate module, a battery management module, and a fire protection module.

[0048] Compared with traditional air cooling, liquid cooling is favored for its higher heat conduction efficiency and the ability to remove more heat in a smaller space. Liquid cooling unit boxes are usually used in high-performance computing devices, data center servers, industrial machinery, and other high heat density application scenarios that require efficient heat dissipation.

[0049] Pressure transmitter: A pressure transmitter is a device that converts a pressure signal into a standard electrical signal, mainly used for measuring the pressure of liquids or gases in industrial process control. It has a wide range of applications in multiple industries such as oil, chemical, power, and water treatment. Through the pressure transmitter, the pressure monitoring of various media can be realized, and it can be converted into an electrical signal that can be transmitted and processed, facilitating remote monitoring and data acquisition and control in automated control systems.

[0050] Pressure color-changing sensor: A pressure color-changing sensor is a special type of sensor that can visually reflect the magnitude of the pressure applied to it through color changes. This type of sensor is usually based on specific technologies in materials science, such as using materials or structures with piezochromic properties, so that when the sensor is subjected to different pressures, it will display different colors.

[0051] Energy storage systems can convert electrical energy into other forms of energy for storage and then convert it back into electrical energy when needed. Energy storage systems are of great significance for balancing peak and valley power demands, improving power grid stability, and promoting the large-scale integration of renewable energy. The safety of energy storage systems is particularly important.

[0052] The main safety problem faced by energy storage systems is the thermal runaway that may be caused by the phenomenon of a sharp rise in the internal temperature of the energy storage system. Therefore, in order to achieve faster heat dissipation and lower temperature differences, existing energy storage systems basically adopt liquid cooling and air cooling methods.

[0053] An air cooling unit box includes main components such as a compressor, condenser, expansion valve, and evaporator. Through the internal refrigerant circulation system, heat is transferred from one place to another to achieve the cooling effect. Compared with an air cooling unit box, since the specific heat capacity and thermal conductivity of the liquid are much higher than that of air, the liquid cooling system has higher heat dissipation efficiency, more uniform temperature and smaller temperature difference inside the module, which helps to improve battery consistency; the liquid cooling unit box also does not require additional duct design, and the volume energy density can be increased by more than 40%, making the structure more compact; when operating under the same conditions and maintaining the same temperature, the energy consumption of the liquid cooling unit box can be reduced by more than 50%, and the operating noise can be reduced by more than 30 dB compared with that of the air cooling unit box. Therefore, due to the excellent heat dissipation ability and temperature control of the liquid cooling unit box, which improves battery consistency, existing energy storage systems mostly use liquid cooling unit boxes to achieve temperature control.

[0054] When the liquid cooling unit box is operating normally, condensate is likely to be generated. However, the entry of condensate into the interior of the liquid cooling unit box may cause an external short circuit of the battery cells or damage to the electronic components on the control components due to a short circuit; or moisture outside the liquid cooling unit box enters the box and condenses to generate condensate, resulting in an external short circuit of the battery cells and damage and failure of the electronic components on the control module due to a short circuit.

[0055] To address the condensate problem, a liquid cooling unit box with a higher protection level needs to be adopted. However, when a thermal runaway occurs in a certain battery cell inside the liquid cooling unit box, a large amount of combustible gas is generated by the battery cell. It is difficult for the combustible gas to spread outside the box, and it is difficult for the combustible gas detector installed outside the energy storage system to detect it, resulting in the fire protection being unable to take corresponding actions in the initial stage of the thermal runaway of the battery cell, leading to the development of the thermal runaway of the battery cells inside the liquid cooling unit box into thermal diffusion, and thus causing a fire.

[0056] The existing technologies for preventing thermal runaway mainly involve installing combustible gas composite detectors, atomizing nozzles, and explosion-proof valves. The service life of the combustible gas composite detector is limited, and maintenance personnel need to replace and verify it on time, increasing the labor cost and material cost. When verifying the combustible gas composite detector, it is necessary to open the liquid cooling unit box, and the moisture outside the box may cause damage to the electronic components and pose safety problems.

[0057] Considering that the liquid cooling unit box is a commonly used device in existing energy storage systems, this application intends to conduct fire protection monitoring based on the liquid cooling unit box.

[0058] Therefore, the fire protection monitoring of the liquid cooling unit box with a high protection level is an urgent problem to be solved at present.

[0059] Based on this, the embodiments of this application provide an explosion-proof valve, a gas detection device, an energy storage system, an energy storage power station, and a control method, which can be used in the field of energy storage safety technology, aiming to solve the above technical problems in the existing technology.

[0060] The technical solutions of this application and how the technical solutions of this application solve the above technical problems will be described in detail below with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0061] Figure 1 It is a schematic diagram of the scenario of the explosion-proof valve provided by the embodiment of this application. It should be noted that Figure 1 The illustration shown is only an example of the scenario in which the embodiments of this application can be applied, to help those skilled in the art understand the technical content of this application, but it does not mean that the embodiments of this application cannot be used in other devices, systems, environments, or scenarios.

[0062] Such as Figure 1As shown, the energy storage system 200 includes a liquid cooling unit box 210 and a fire control host 220. The gas detection device 300 includes a camera 310. The energy storage power station 400 includes an energy storage power station fire control room 410 and a station-end monitoring terminal 420.

[0063] The explosion-proof valve 100 is installed on the liquid cooling unit box 210 of the energy storage system 200. The pressure color-changing sensor of the explosion-proof valve 100 can convert pressure data into electrical signal data and generate a color change. The camera 310 of the gas detection device 300 can observe in real time. The pressure transmitter of the explosion-proof valve 100 can send the electrical signal data to the fire control host 220 of the energy storage system 200 and the station-end monitoring terminal 420 of the energy storage power station 400, and the fire control host 220 and the station-end monitoring terminal 420 send different instructions such as audible and visual alarms, smoke exhaust and ventilation of the energy storage system, and spraying of fire extinguishing gas.

[0064] When the air pressure in the liquid cooling unit box 210 is too high and reaches the preset valve opening value, the gas in the liquid cooling unit box 210 pushes the explosion-proof valve assembly of the explosion-proof valve 100, thereby reducing the gas pressure in the liquid cooling unit box and preventing the liquid cooling unit box from exploding.

[0065] Figure 2 It is the front view of the explosion-proof valve provided by the embodiment of the present application. Figure 3 It is a schematic diagram of the explosion-proof valve provided by the embodiment of the present application. This embodiment is based on the Figure 1 scenario and details the explosion-proof valve 100. As Figure 2 and Figure 3 shown, the explosion-proof valve 100 includes an explosion-proof valve housing 110, an explosion-proof valve assembly 120, a pressure color-changing sensor 130, and a pressure transmitter 140;

[0066] Among them, the explosion-proof valve housing 110 is used to encapsulate the explosion-proof valve assembly 120, the pressure color-changing sensor 130, and the pressure transmitter 140;

[0067] Among them, the explosion-proof valve assembly 120 includes an explosion-proof valve top cover 121 and an explosion-proof valve pressure-sensing travel mechanism 122. The explosion-proof valve pressure-sensing travel mechanism 122 is fixedly connected to the explosion-proof valve top cover 121 so as to operate and push open the explosion-proof valve top cover 121 when the explosion-proof valve pressure-sensing travel mechanism 122 is stressed;

[0068] The pressure color-changing sensor 130 is electrically connected to the pressure transmitter 140. The pressure color-changing sensor 130 is used to collect air pressure change data, convert the air pressure change into voltage change data to generate color change information, and transmit the pressure change data to the pressure transmitter 140;

[0069] The pressure transmitter 140 is used to convert the pressure change data into electrical signal change data and send the processed electrical signal change data to the upper computer.

[0070] Specifically, the explosion-proof valve 100 includes an explosion-proof valve housing 110, an explosion-proof valve assembly 120, a pressure color-changing sensor 130, and a pressure transmitter 140.

[0071] The explosion-proof valve housing 110 encapsulates the explosion-proof valve assembly 120, the pressure color-changing sensor 130, and the pressure transmitter 140.

[0072] The explosion-proof valve assembly 120 includes an explosion-proof valve top cover 121 and an explosion-proof valve pressure-sensing travel mechanism 122. When the air pressure in the liquid cooling unit box 210 is too high and reaches the preset valve-opening value, the gas in the liquid cooling unit box 210 pushes the explosion-proof valve pressure-sensing travel mechanism 122 to operate, pushing open the explosion-proof valve top cover 121 to release air, so as to reduce the gas pressure in the liquid cooling unit box 210 and prevent the liquid cooling unit box 210 from exploding.

[0073] The pressure color-changing sensor 130 includes a microstructured polymeric piezoelectric material unit, an electrochromic material unit, and a transparent sealing cover. The microstructured polymeric piezoelectric material unit of the pressure color-changing sensor 130 converts the pressure change into voltage change data, and the electrochromic material unit generates color change information based on the voltage change data. When the gas in the liquid cooling unit box 210 changes, the microstructured polymeric piezoelectric material unit converts the pressure change into voltage change data, the electrochromic material unit generates a color change according to the voltage change data, and transmits the pressure change data to the pressure transmitter 140. The pressure color-changing sensor 130 is electrically connected to the pressure transmitter 140. The microstructured polymeric piezoelectric material unit, the electrochromic material unit, and the transparent sealing cover cooperate and are encapsulated in the explosion-proof valve housing 110.

[0074] The pressure transmitter 140 can select a variety of transmitters. When the pressure transmitter 140 is a diffused silicon pressure transmitter, the diffused silicon pressure transmitter includes a diffused silicon chip, an anti-interference signal processing unit, and a communication socket. The diffused silicon chip converts the pressure change data into a stable electrical signal for output. When the gas pressure in the liquid cooling unit changes, the electrical signal generated by the diffused silicon chip starts to change, and the anti-interference signal processing unit processes the electrical signal change and outputs it through the communication socket.

[0075] The upper computer can be devices such as a host and a server, such as a fire host, which can obtain the change data and make corresponding countermeasures in a timely manner.

[0076] An explosion-proof valve provided by the present application includes an explosion-proof valve housing, an explosion-proof valve assembly, a pressure color-changing sensor, and a pressure transmitter. Among them, the explosion-proof valve housing is used to encapsulate the explosion-proof valve assembly, the pressure color-changing sensor, and the pressure transmitter. Among them, the explosion-proof valve assembly includes an explosion-proof valve top cover and an explosion-proof valve pressure-sensing travel mechanism. The explosion-proof valve pressure-sensing travel mechanism is fixedly connected to the explosion-proof valve top cover so as to operate and push open the explosion-proof valve top cover when the explosion-proof valve pressure-sensing travel mechanism is stressed. The pressure color-changing sensor is electrically connected to the pressure transmitter. The pressure color-changing sensor is used to collect air pressure change data, convert the air pressure change into voltage change data to generate color change information, and transmit the pressure change data to the pressure transmitter. The pressure transmitter is used to convert the pressure change data into electrical signal change data and send the processed electrical signal change data to the host computer. The following technical effects are achieved: By using the pressure color-changing sensor to collect air pressure change data in real time and convert the air pressure change data into voltage change data to generate a color change, the result can be observed in a timely manner; the pressure transmitter transmits the electrical signal change data to the host computer in real time, enabling timely transmission of the observation results of the energy storage system, realizing dual monitoring, and at the same time reducing the configuration of maintenance personnel for the energy storage system; through the design of the explosion-proof valve, replacing the original combustible gas composite detector can cover the entire life cycle of the energy storage system, saving the material and labor costs for installation, replacement, and detection of the composite detector, and at the same time avoiding the safety hazards caused by disassembling and assembling the liquid cooling unit box.

Figure 4 is Figure 2 The partial method schematic diagram of part A of the pressure color-changing sensor in FIG. As Figure 4 shown, the pressure color-changing sensor 130 includes a microstructured polymeric piezoelectric material unit 131 and an electrochromic material unit 132.

[0078] Among them, the microstructured polymeric piezoelectric material unit 131 is electrically connected to both the electrochromic material unit 132 and the pressure transmitter 140.

[0083] The electrochromic material unit 132 will generate corresponding color change data according to the voltage change data.

[0084] The microstructured polymeric piezoelectric material unit 131 and the electrochromic material unit 132 are encapsulated into the explosion-proof valve housing 110 by cooperating with the transparent sealing cover 133.

[0085] The microstructured polymeric piezoelectric material unit 131, the electrochromic material unit 132 and the pressure transmitter 140 are all electrically connected, so as to transmit the pressure change data in a timely manner.

[0086] The technical effect provided by this embodiment is that the color change of the electrochromic material unit can be captured and observed by a camera; in addition, the pressure change data can be transmitted to the pressure transmitter in a timely manner, and dual monitoring can be realized.

As Figure 5 shown, the pressure transmitter 140 is a diffused silicon pressure transmitter, and the diffused silicon pressure transmitter includes a diffused silicon chip 141, an anti-interference signal processing unit 142, and a communication socket 143.

[0091] Among them, the diffused silicon chip 141 is electrically connected to both the pressure color-changing sensor 130 and the anti-interference signal processing unit 142. The diffused silicon chip 141 is used to convert pressure change data into electrical signal change data and transmit the electrical signal change data to the anti-interference signal processing unit 142;

[0092] The anti-interference signal processing unit 142 is electrically connected to the communication socket 143. The anti-interference signal processing unit is used to process the electrical signal change data and send it to the host computer through the communication socket.

[0093] Specifically, when the pressure transmitter 140 is a diffused silicon pressure transmitter, the diffused silicon pressure transmitter includes a diffused silicon chip 141, an anti-interference signal processing unit 142, and a communication socket 143.

[0094] The diffused silicon chip 141 can convert pressure change data into electrical signal change data and transmit the electrical signal change data to the anti-interference signal processing unit 142.
