[0025] Compared with the prior art, the beneficial effects of this application are at least as follows:
[0026] Because the outlet of the first extinguishing agent supply unit, the battery cell module, and the aerosol generator are all located inside the module housing; the aerosol generator produces aerosol when a fire occurs; and the first extinguishing agent supply unit provides extinguishing agent from the outlet when a fire occurs, the aerosol generator can produce aerosol inside the module housing when a fire breaks out. This aerosol can be used for fire extinguishing, and the first extinguishing agent supply unit can also provide extinguishing agent into the module housing through the outlet. This gives the battery cell module fire extinguishing capabilities, improving its fire-fighting performance. This allows for timely fire extinguishing inside the module housing, effectively preventing the spread of fire and thus avoiding fires in the power grid system.

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0038] Currently, some regions experience an imbalance between electricity consumption and power generation during certain periods, resulting in peak and off-peak electricity loads. Specifically, electricity consumption is generally higher during the day and lower at night. Power generation, however, is relatively even across these periods, leading to a supply-demand imbalance. To address this issue, energy storage units are typically connected to the power grid to achieve peak shaving and valley filling.
[0039] However, due to the large size of energy storage cabinets, they are generally installed outdoors. In summer, the outdoor temperature is high, and the battery modules inside the cabinet also generate heat during operation. As the heat accumulates, the battery modules may spontaneously combust, potentially causing a fire in the entire power grid system and resulting in huge economic losses.
[0040] Based on the aforementioned technical problems, the battery cell module provided by this utility model solves these problems by incorporating a discharge port of a first fire extinguishing agent supply and an aerosol generating device inside the battery cell module. Specifically, the battery cell module includes a module shell, a battery cell module, an aerosol generating device, a first fire extinguishing agent supply, and a liquid cooling plate. Since the discharge port of the first fire extinguishing agent supply, the battery cell module, and the aerosol generating device are all located inside the module shell; the aerosol generating device generates aerosol when a fire occurs; and the first fire extinguishing agent supply provides fire extinguishing agent from the discharge port when a fire occurs. Thus, when a fire occurs inside the module shell, the aerosol generating device can generate aerosol inside the module shell, which can be used for fire extinguishing. Simultaneously, the first fire extinguishing agent supply can also provide fire extinguishing agent to the inside of the module shell through the discharge port. This gives the battery cell module fire extinguishing capabilities, improving its fire-fighting performance. Furthermore, it enables timely fire extinguishing inside the module shell, effectively preventing the spread of fire and thus avoiding fires in the power grid system.
[0041] Furthermore, since the liquid cooling plate is located inside the module housing, sandwiched between the battery cell module and the module housing, it can effectively absorb the heat generated by the battery cell module during operation. This effectively prevents the heat from accumulating and thus avoids spontaneous combustion of the battery cell module, thereby reducing the probability of fire at the source.
[0042] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.
[0043] The following provides a detailed description of the specific structure of the aforementioned battery cell module and various possible implementation methods.
[0044] Figure 1 This is an exploded view of a battery cell module 110 provided in an embodiment of this application. Figure 2 for Figure 1 Top view of the 112 module of China Electronics Technology Group Corporation (CETC). Figure 3 for Figure 1 A schematic diagram of the module housing 111 of the cell module 110.
[0045] See Figure 1 , Figure 2 and Figure 3The battery module 110 includes a module housing 111, a battery module 112, an aerosol generator 113, a first extinguishing agent supply unit 114, and a liquid cooling plate 115. The outlet of the first extinguishing agent supply unit 114, the battery module 112, and the aerosol generator 113 are all located inside the module housing 111. The aerosol generator 113 generates aerosol when a fire occurs. The first extinguishing agent supply unit 114 provides extinguishing agent from the outlet when a fire occurs. The liquid cooling plate 115 is located inside the module housing 111, sandwiched between the battery module 112 and the module housing 111.
[0046] In this embodiment, the outlet of the first extinguishing agent supply unit 114, the battery cell module 112, and the aerosol generator 113 are all located inside the module housing 111. The aerosol generator 113 generates aerosol when a fire occurs, and the first extinguishing agent supply unit 114 provides extinguishing agent from the outlet when a fire occurs. Thus, when a fire occurs inside the module housing 111, the aerosol generator 113 can generate aerosol inside the module housing 111, which can be used for fire extinguishing. Simultaneously, the first extinguishing agent supply unit 114 can also provide extinguishing agent to the inside of the module housing 111 through the outlet. This gives the battery cell module 110 fire extinguishing capabilities, improving its fire-fighting performance. Furthermore, it enables timely fire extinguishing inside the module housing 111, effectively preventing the spread of fire and thus avoiding fires in the power grid system.
[0047] Furthermore, since the liquid cooling plate 115 is located inside the module housing 111, sandwiched between the battery cell module 112 and the module housing 111, the liquid cooling plate 115 can absorb the heat generated by the battery cell module 112 during operation in a timely manner, effectively preventing the accumulation of heat generated by the battery cell module 112 during operation, thereby preventing the battery cell module 112 from spontaneously combusting, and thus reducing the probability of fire from the source.
[0048] It should be noted that the principles of aerosol fire extinguishing include both physical and chemical inhibition. In terms of physical inhibition, the heat absorption and diffusion of aerosols can reduce the flame temperature. Solid particles in aerosols require a certain amount of time to be heated and decomposed in a fire, and they cannot be completely decomposed or vaporized. These solid particles can absorb some of the heat released by the fire source, thereby reducing the flame temperature and inhibiting the combustion reaction. In terms of chemical inhibition, chemical reactions consume active groups in the flame, achieving a chain-breaking effect. The surface of solid particles in aerosols can adsorb and consume active groups in the flame, thereby inhibiting the combustion reaction.
[0049] It should also be noted that the aforementioned first extinguishing agent supply component 114 is a first fire sprinkler head, which can spray atomized extinguishing agent when a fire occurs. This allows the extinguishing agent to diffuse fully within the module housing 111, thereby improving the fire extinguishing effect of the battery module 110.
[0050] It should also be noted that the above-mentioned extinguishing agent can be perfluorohexanone, liquid carbon dioxide, or other types of extinguishing agents, and the embodiments of this application do not limit this.
[0051] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The discharge port is located on the inner wall of the module housing 111. The aerosol generating device 113 includes an aerosol generating element 1131 and a first temperature detection element 1132 connected to each other; the aerosol generating element 1131 and the first temperature detection element 1132 are respectively disposed on two interconnected surfaces of the battery cell module 112; when the temperature detected by the first temperature detection element 1132 exceeds a first temperature threshold, the aerosol generating element 1131 generates aerosol.
[0052] In this embodiment, the discharge port is located on the inner wall of the module housing 111. This facilitates the first extinguishing agent supply unit 114 in providing extinguishing agent to the interior of the module housing 111 in the event of a fire. The aerosol generating device 113 includes an interconnected aerosol generating element 1131 and a first temperature sensing element 1132; the aerosol generating element 1131 and the first temperature sensing element 1132 are respectively disposed on two interconnected surfaces of the cell module 112. This is advantageous compared to disposing of the aerosol generating element 1131 and the first temperature sensing element 1132 on only one surface of the cell module 112, as it allows for full utilization of the space inside the module housing, thus facilitating the miniaturization design of the cell module 110.
[0053] When the temperature detected by the first temperature sensor 1132 exceeds the first temperature threshold, the aerosol generator 1131 generates aerosol. This allows the aerosol generator 1131 to automatically generate aerosol by detecting the temperature of the battery module 112, thereby enabling automatic control of the aerosol generator 113.
[0054] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The first temperature detection element 1132 is a thermal wire, and all the cells 1121 of the cell module 112 are connected to the thermal wire.
[0055] In this way, as long as the temperature of any one of the cells 1121 in the cell module 112 reaches the first temperature threshold, the aerosol generator 1131 can be triggered to generate aerosol. This enables comprehensive monitoring of all cells 1121 in the cell module 112, thus further enhancing the fire protection capability of the cell module 110.
[0056] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The battery cell module 110 includes a second temperature detection element, which is disposed on the surface of the battery cell module 112 and electrically connected to the first fire extinguishing agent supply element 114. When the temperature detected by the second temperature detection element exceeds a second temperature threshold, the first fire extinguishing agent supply element 114 provides fire extinguishing agent.
[0057] This allows the first fire extinguishing agent supply unit 114 to automatically supply fire extinguishing agent by detecting the temperature of the battery cell module 112, thereby enabling automatic control of the first fire extinguishing agent supply unit 114.
[0058] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The module housing 111 includes a first housing 1111 with an opening, a second housing 1112 with an opening, and a sealing member 1113. The side of the first housing 1111 with an opening and the side of the second housing 1112 with an opening are detachably connected to form an accommodating cavity, and the battery cell module 112 is located within the accommodating cavity. The sealing member 1113 is sandwiched between the first housing 1111 and the second housing 1112.
[0059] Since the first housing 1111 with an opening side and the second housing 1112 with an opening side are detachably connected to form an accommodating cavity, and the battery cell module 112 is located inside the accommodating cavity, this facilitates the assembly of the battery cell module 110. Specifically, when assembling the battery cell module 110, the battery cell module 112 can be placed into one of the first housing 1111 and the second housing 1112 first, and then the opening side of the first housing 1111 can be connected to the opening side of the second housing 1112, thus improving the assembly efficiency of the battery cell module 110.
[0060] Because the sealing element 1113 is sandwiched between the first housing 1111 and the second housing 1112, gaps are avoided when the first housing 1111 and the second housing 1112 are connected, ensuring that a sealed accommodating cavity can be formed inside the module housing 111. This further prevents fire inside the module housing 111 from spreading to the outside of the module housing, thus further improving the fire protection capability of the battery cell module 110.
[0061] The module housing 111 is equipped with an explosion-proof vent valve 1114 to remove excess gas inside the module housing 111 to ensure the safety of the battery cell module 110. In addition, the module housing 111 is also equipped with an inspection port 1115, which is detachably and sealed to the inspection cover plate 116 of the battery cell module 110.
[0062] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application embodiment also provides an energy storage cabinet 100, which includes a cabinet body 120 and any of the above-mentioned battery cell modules 110, with the battery cell modules 110 located inside the cabinet body 120.
[0063] In this embodiment, the outlet of the first extinguishing agent supply unit 114, the battery cell module 112, and the aerosol generator 113 are all located inside the module housing 111. The aerosol generator 113 generates aerosol when a fire occurs, and the first extinguishing agent supply unit 114 provides extinguishing agent from the outlet when a fire occurs. Thus, when a fire occurs inside the module housing 111, the aerosol generator 113 can generate aerosol inside the module housing 111, which can be used for fire extinguishing. Simultaneously, the first extinguishing agent supply unit 114 can also provide extinguishing agent to the inside of the module housing 111 through the outlet. This gives the battery cell module 110 fire extinguishing capabilities, improving its fire-fighting performance and consequently improving the fire-fighting performance of the energy storage cabinet 100. This enables timely fire extinguishing inside the module housing 111, effectively preventing the spread of fire and thus avoiding fires in the power grid system.
[0064] Because the liquid cooling plate 115 is located inside the module housing 111, sandwiched between the battery cell module 112 and the module housing 111, the liquid cooling plate 115 can absorb the heat generated by the battery cell module 112 during operation in a timely manner. This effectively prevents the accumulation of heat generated by the battery cell module 112 during operation, thereby preventing the battery cell module 112 from spontaneously combusting. Therefore, it can reduce the probability of fire from the source and further improve the fire protection performance of the energy storage cabinet 100.
[0065] Furthermore, since the energy storage cabinet 100 includes a cabinet body 120, the battery cell module 110 is located inside the cabinet body 120. In this way, the cabinet body 120 can protect the battery cell module 110, thereby extending the service life of the energy storage cabinet 100. At the same time, the cabinet body 120 can also prevent a fire inside the cabinet body 120 from spreading to the outside, thus further enhancing the fire-fighting capability of the energy storage cabinet 100.
[0066] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The energy storage cabinet 100 includes a fire extinguishing agent container 130 and a fire-fighting pipeline 140. The fire extinguishing agent container 130 is located inside the cabinet 120 and contains fire extinguishing agent. Both the fire extinguishing agent container 130 and the first fire extinguishing agent supply unit 114 of the battery module 110 are connected to the fire-fighting pipeline 140. A one-way valve 150 is installed between the fire extinguishing agent container 130 and the fire-fighting pipeline 140 to control the flow of fire extinguishing agent from the fire extinguishing agent container 130 to the fire-fighting pipeline 140. The fire-fighting pipeline 140 is connected to an external water pipe.
[0067] In this embodiment, the energy storage cabinet 100 includes a fire extinguishing agent container 130 and a fire-fighting pipeline 140. The fire extinguishing agent container 130 is located inside the cabinet 120 and contains fire extinguishing agent. Both the fire extinguishing agent container 130 and the first fire extinguishing agent supply unit 114 of the battery cell module 110 are connected to the fire-fighting pipeline 140. Thus, when a fire occurs, the fire extinguishing agent in the fire extinguishing agent container 130 can be delivered to the first fire extinguishing agent supply unit 114 through the fire-fighting pipeline 140, and then enter the module housing 111 through the first fire extinguishing agent supply unit 114, thereby achieving the purpose of fire extinguishing.
[0068] A one-way valve 150 is installed between the extinguishing agent container 130 and the fire pipeline 140. The one-way valve 150 is used to control the flow of extinguishing agent from the extinguishing agent container 130 to the fire pipeline 140. This prevents liquid from flowing from the fire pipeline 140 into the extinguishing agent container 130, thereby avoiding contamination of the extinguishing agent in the extinguishing agent container 130.
[0069] Because the fire extinguishing pipeline 140 is connected to an external water pipe, it can transport both fire extinguishing agent and water. Since water can be used for fire extinguishing, this further enhances the fire protection performance of the energy storage cabinet 100. The external water pipe is manually controlled by staff.
[0070] It should also be noted that the energy storage cabinet 100 includes a fire suppression module 160, which is located inside the cabinet 120. The aforementioned fire extinguishing agent container 130 is disposed within the fire suppression module 160.
[0071] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The top of the inner wall of the cabinet 120 is equipped with a second fire extinguishing agent supply unit 170, which is connected to the fire pipeline 140.
[0072] In the event of a fire, the second extinguishing agent supply unit 170, located at the top of the inner wall of the cabinet 120, can provide extinguishing agent from the top of the cabinet 120. This ensures that even if a fire inside the module housing 111 spreads to the outside, it can be extinguished by the extinguishing agent supplied by the second extinguishing agent supply unit 170. Therefore, the fire protection performance of the energy storage cabinet 100 is further improved. When the fire-fighting pipeline 140 is connected to an external water pipe, water can be supplied through the second extinguishing agent supply unit 170 for fire suppression.
[0073] It should also be noted that the aforementioned second extinguishing agent supply unit 170 is a second fire sprinkler head, which can spray atomized extinguishing agent when a fire occurs. This allows the extinguishing agent to fully diffuse within the cabinet 120, thereby improving the fire extinguishing effect of the energy storage cabinet 100.
[0074] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A fire detection assembly 121 is installed on the top of the inner wall of the cabinet 120. The fire detection assembly 121 includes a smoke detection module 1211 and a temperature detection module 1212 that are connected to each other. The smoke detection module 1211 and the temperature detection module 1212 of the fire detection assembly 121 can monitor the smoke concentration and temperature inside the cabinet 120 in real time.
[0075] The temperature sensing module 1212 is electrically connected to the second extinguishing agent supply unit 170. When the smoke concentration detected by the smoke sensing module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensing module 1212 exceeds the third temperature threshold, the second extinguishing agent supply unit 170 is triggered to open to provide extinguishing agent. This enables automatic control of the second extinguishing agent supply unit 170, ensuring that it can open promptly when a fire occurs in the energy storage cabinet 100.
[0076] Alternatively, the temperature sensing module 1212 can be electrically connected to the aerosol generator 113 of the battery module 110; when the smoke concentration detected by the smoke sensing module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensing module 1212 exceeds the third temperature threshold, the aerosol generator 113 is triggered to generate aerosol. In this way, the aerosol generator 113 can be automatically controlled to open by the smoke sensing module 1211 and the temperature sensing module 1212 of the fire detection component 121, thereby enabling fire extinguishing inside the module housing 111.
[0077] It should be noted that when the smoke concentration detected by the smoke sensor module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensor module 1212 exceeds the third temperature threshold, the second extinguishing agent supply unit 170 and the aerosol generator 113 can be activated simultaneously. This further enhances the fire-fighting capability of the energy storage cabinet 100.
[0078] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The energy storage cabinet 100 includes an alarm device, and the temperature sensing module 1212 is electrically connected to the alarm device. When the smoke concentration detected by the smoke sensing module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensing module 1212 is less than the third temperature threshold, the alarm device is triggered.
[0079] In this way, when a fire occurs, the alarm device can sound an alarm, allowing staff to be aware of the fire in a timely manner and take corresponding measures to prevent the fire from spreading.
[0080] Specifically, when the smoke concentration detected by the smoke sensor module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensor module 1212 is less than the third temperature threshold, the temperature sensor module 1212 will trigger an alarm. If, upon noticing this, staff manually open the external water pipe, the second extinguishing agent supply unit 170 can provide water to extinguish the fire. If staff are unaware of this or fail to manually open the external water pipe in time, the alarm will continue to sound. As time progresses and the fire worsens, when the smoke concentration detected by the smoke sensor module 1211 exceeds the smoke concentration threshold and the temperature detected by the temperature sensor module 1212 is equal to or exceeds the third temperature threshold, the second extinguishing agent supply unit 170 can automatically open to provide extinguishing agent and extinguish the fire, at which point the alarm will stop.
[0081] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.
[0082] Generally speaking, terms should be understood at least in part by their use in context.
