Description

Technical Field

[0001] This disclosure relates to the field of fire protection technology, and in particular to fire protection systems for energy storage batteries. Background Technology

[0002] In related technologies, fire suppression systems for energy storage batteries use clean gases such as nitrogen and argon to extinguish fires within the batteries of the energy storage module. However, the release time of these clean gases is short and they cannot prevent the spread and reignition of the fire, thereby reducing the fire suppression capability of fire suppression systems for energy storage batteries. Summary of the Invention

[0003] To address the above technical problems, this disclosure provides a fire protection system for energy storage batteries.

[0004] The fire suppression system for energy storage batteries provided in this disclosure includes an energy storage module, a storage module, a release module, a delivery module, and a control module. The energy storage module has a housing space in which multiple batteries are disposed. The storage module is disposed externally. The storage module includes a storage container for storing carbon dioxide. The release module includes a dry ice generator for generating solid carbon dioxide. The dry ice generator is in communication with the release component. The release component is disposed within the housing space. The release component is located on one side of the battery. Alternatively or additionally, the release component is located inside the battery. The release component is used to release one or more of solid carbon dioxide, liquid carbon dioxide, and gaseous carbon dioxide. The delivery module includes a delivery conduit, one end of which is in communication with the storage container, and the other end of which is in communication with the release module. The control module includes a controller electrically connected to the storage module, the release module, and the delivery module, respectively.

[0005] Compared with existing technologies, the technical solution provided in the embodiments of this disclosure has the following advantages: the dry ice generator of the release module is connected to the storage container of the storage module via a delivery pipe, and the release component is connected to the dry ice generator. Therefore, when a fire occurs in the energy storage module, the controller of the control module can control the release component to release carbon dioxide from the storage container. Additionally, the dry ice generator can also be controlled to produce solid carbon dioxide. The solid carbon dioxide released by the release component can cover the burning battery. This allows a dry ice layer of carbon dioxide to form on the battery, which extinguishes the fire while isolating the battery. This prevents the spread of the fire and the reignition of the extinguished battery, thereby improving the fire-fighting capability of the fire suppression system. Furthermore, the solid carbon dioxide also avoids damage to the battery. The solid carbon dioxide can be returned to the external environment during ventilation of the energy storage module, thus minimizing user losses and improving the user experience. In addition, the carbon dioxide released by the fire suppression system does not cause environmental pollution, thus enhancing the system's environmental protection capabilities.

[0006] In one possible implementation, the fire suppression system for the energy storage battery also includes a movable component that is movably disposed within the housing space, wherein a release member is connected to the movable component.

[0007] In one possible implementation, the fire suppression system for the energy storage battery further includes a detection module electrically connected to the controller. The detection module includes a detector, which is disposed within the housing space.

The exhaust pressure relief module is located externally to the energy storage module and communicates with an internal containment space within the energy storage module.

[0009] In one possible implementation, the delivery module further includes a first valve assembly and a second valve assembly. The first valve assembly is disposed on the side of the delivery pipe near the storage module. The first valve assembly is electrically connected to a controller. The first valve assembly controls the communication between the storage container and the release module. The second valve assembly is disposed on the side of the delivery pipe near the release member. The second valve assembly is electrically connected to the controller. The second valve assembly controls the pressure and flow rate in the delivery pipe. A dry ice generator is disposed between the first valve assembly and the second valve assembly. Alternatively or additionally, the dry ice generator is disposed between the second valve assembly and the release member.

[0010] In one possible implementation, the first valve assembly includes an on / off valve and a check valve. Both the on / off valve and the check valve are located on the delivery pipeline.

[0011] In one possible implementation, the second valve assembly includes a pressure valve and a flow valve arranged sequentially, both of which are located on the delivery pipeline.

[0012] In one possible implementation, the storage module further includes a refrigeration unit, a pressure-temperature controller, and a pressure-temperature detector. The refrigeration unit is configured to change the state of carbon dioxide within the storage container. The pressure-temperature controller is configured to control the temperature and pressure inside the storage container. The pressure and temperature detector is configured to detect the temperature and pressure inside the storage container.

[0013] In one possible implementation, the storage module further includes a storage capacity detector electrically connected to the controller. The storage level detector is configured to detect the storage capacity of the storage container.

[0014] In one possible implementation, the release member includes a first release member and a second release member. The first release member is located at the edge of the battery. The first release member has a first release hole. The second release member is spaced apart from the first release member. The second release member is located between two adjacent batteries. Alternatively or additionally, the second release member is located inside the battery. The second release member has a second release hole.

[0015] In one possible implementation, the delivery module further includes a multi-way valve. The multi-way valve includes a first port, a second port, and a third port, wherein the first port is in communication with one or more of the second and third ports. The delivery conduit includes a main conduit, a first conduit, and a second conduit. One end of the main conduit is in communication with a storage container, and the other end of the main conduit is in communication with the first port; one end of the first conduit is in communication with a first release member, and the other end of the first conduit is in communication with the second port; one end of the second conduit is in communication with a second release member, and the other end of the second conduit is in communication with the third port.

[0016] In one possible implementation, the fire suppression system for the energy storage battery includes multiple energy storage modules. The multiple energy storage modules are arranged in multiple rows and columns, with a storage module located in the middle of the multiple energy storage modules.

[0017] In one possible implementation, the fire suppression system for the energy storage battery includes multiple storage modules. These storage modules are arranged at intervals along the periphery of the energy storage module.

[0036] To provide a clearer understanding of the objectives, features, and advantages mentioned above in this disclosure, the solutions of this disclosure will be further described below. It should be noted that, unless otherwise specified, embodiments of this disclosure and features thereof can be combined with each other.

[0037] Numerous specific details are set forth in the following description to provide a full understanding of this disclosure. However, it will be apparent that this disclosure may be implemented in ways other than those described herein. The embodiments described in the specification are merely some, and not all, of the embodiments described herein.

[0038] Reference Figure 1 . Figure 1 This is a schematic diagram of a fire protection system for an energy storage battery provided in some embodiments of this disclosure. The fire protection system 100 for an energy storage battery provided in the embodiments of this disclosure may include an energy storage module 1, a storage module 2, a release module 3, a delivery module 4, and a control module 5. The control module 5 may include a controller 51. The controller 51 is electrically connected to the storage module 2, the release module 3, and the delivery module 4, respectively. Therefore, by controlling the storage module 2, the release module 3, and the delivery module 4 through the controller 51, the automation level of the fire protection system 100 for the energy storage battery can be improved.

[0039] The energy storage module 1 has a receiving space 11. Specifically, the receiving space 11 can be formed by enclosing the shell of the energy storage module 1. The energy storage module 1 can be formed in the shape of, for example, a cube, a cylinder, etc., and this disclosure is not limited thereto. The receiving space 11 can be a completely enclosed space, or the receiving space 11 can be a partially enclosed or completely open space. For example, the receiving space 11 can have an opening communicating with the outside of the energy storage module 1.

[0040] Multiple batteries 12 can be housed within the accommodating space 11. For example, the energy storage module 1 can be located in areas involved in the production process of the battery 12, such as workshops, loading and unloading platforms, test beds, warehouses, storage locations, shelves, supports, or test lines. The energy storage module 1 can also be located in areas where the battery 12 is used, such as energy storage boxes or energy storage cabinets.

[0041] Here, the phrase "multiple batteries" refers to two or more batteries 12. The multiple batteries 12 may be arranged at intervals within the housing space 11.

[0042] It should be noted that battery 12 may be a battery in production, under testing, undergoing charging or discharging, in a static state, in the formation or pre-formation stage, or in a storage state.

[0043] The storage module 2 is located outside the energy storage module 1, meaning it is situated in the external space. Therefore, the problem of the storage module 2 failing to provide proper fire suppression capabilities due to a fire occurring in the energy storage module 1 can be avoided, thus improving the reliability of the storage module 2 and ensuring the fire-fighting capability of the fire suppression system 100 used for the energy storage battery.

[0044] Storage module 2 includes storage container 21. Storage container 21 is used to store carbon dioxide. Specifically, the carbon dioxide stored in storage container 21 can be solid carbon dioxide, liquid carbon dioxide, or gaseous carbon dioxide. The storage capacity can be designed according to the amount of carbon dioxide required for fire fighting in energy storage module 1. For example, 20 tons of carbon dioxide can be stored in storage container 21.

[0045] The delivery module 4 may include a delivery pipe 41. One end of the delivery pipe 41 is connected to the storage container 21. Therefore, carbon dioxide stored in the storage container 21 can be introduced into the delivery pipe 41.

[0046] The release module 3 can be connected to the other end of the delivery pipe 41. The release module 3 may include a dry ice generator 31. One end of the dry ice generator 31 can be connected to the delivery pipe 41. Therefore, gaseous or liquid carbon dioxide flowing from the storage container to the delivery pipe 41 can be converted into solid carbon dioxide by the dry ice generator 31.

[0047] The release module 3 may also include a release member 32. The release member 32 may be connected to the dry ice generator 31. Therefore, when the dry ice generator 31 is working, the release member 32 may release solid carbon dioxide. When the dry ice generator 31 stops working, the release member 32 may directly release carbon dioxide, such as gaseous carbon dioxide or solid carbon dioxide, stored in the storage container 21.

[0048] Specifically, under the control of the controller 51, the release component 32 can increase the concentration of carbon dioxide in the energy storage module 1 to the minimum fire extinguishing concentration within a preset time (e.g., 60 seconds), and can maintain the preset fire extinguishing time as needed.

[0049] The release member 32 can be disposed in the receiving space 11 or located on one side of the battery 12. Therefore, the release member 32 can release carbon dioxide from the outside of the battery to the battery 12.

[0050] The spraying component 32 can also be located inside the battery 12. Therefore, the release component 32 can spray carbon dioxide from inside the battery to the battery 12, which is beneficial to improving the fire-fighting capability of the fire protection system 100.

[0051] The release member 32 can be located both outside and inside the battery 12. Therefore, the release member 32 can release carbon dioxide not only from inside the battery 12 to the battery, but also from outside the battery 12 to the battery, thus further improving the fire protection capability of the fire protection system 100.

[0052] Therefore, when the dry ice generator 31 is running, the release component 32 can release solid carbon dioxide, which can cover the surface of the battery 12, thereby forming a carbon dioxide dry ice layer on the surface of the battery 12. The carbon dioxide dry ice layer can directly freeze the burning battery 12 and also isolate the battery 12, thus preventing the spread of fire and improving the fire-fighting capability of the fire protection system 100. Compared with the clean gases used in related technologies, solid carbon dioxide can last for a longer period of time. In addition, solid carbon dioxide can also avoid damage to the battery 12, thereby reducing losses to users and improving the user experience. Furthermore, since the solid carbon dioxide can be returned to the external environment after the energy storage module 1 is ventilated, the energy storage module 1 can resume operation immediately after the fire is extinguished.

[0053] It should be noted that the release member 32 can be fixed in the receiving space 11, or the release member 32 can also move in the receiving space 11.

[0054] In the fire suppression system 100 for an energy storage battery according to an embodiment of the present disclosure, the dry ice generator 31 of the release module 3 is connected to the storage container 21 of the storage module 2 via a delivery pipe 41, and the release member 32 is connected to the dry ice generator 31. Therefore, when a fire occurs in the energy storage module 1, the controller 51 of the control module 5 can control the release member 32 to release carbon dioxide from the storage container 21. The dry ice generator 31 can also be controlled to produce solid carbon dioxide, which, when released by the release member 32, can cover the burning battery 12, thereby forming a dry ice layer on the battery 12 and isolating the battery 12 while extinguishing the fire. Therefore, the spread of the fire can be prevented, and the reignition of the extinguished battery 12 can also be prevented, thus improving the fire suppression capability of the fire suppression system 100. Furthermore, the solid carbon dioxide can prevent damage to the battery 12, and the solid carbon dioxide can return to the external environment after the energy storage module 1 is ventilated, reducing user losses and thus improving the user experience. In addition, the carbon dioxide released by the fire protection system 100 will not pollute the environment, thereby improving the environmental protection capability of the fire protection system 100.

[0055] Refer again Figure 1 In some embodiments, the fire protection system 100 for energy storage batteries may further include a movable component. This movable component is movably disposed within the housing space 11. A release member 32 is connected to the movable component. Therefore, the release member 32 can move together with the movable component and thus can be moved to a designated location as required by the fire protection system 100, thereby improving the accuracy of fire suppression by the fire protection system 100.

[0056] For example, the moving component may include a guide rail, a moving member, and a drive motor. The moving member is slidably connected to the guide rail. The drive motor drives the moving member to slide on the guide rail, and a release member 32 may be connected to the moving member. Therefore, when the moving member moves, it can drive the release member 32 to move.

[0057] Refer again Figure 1In some embodiments, the fire protection system 100 may further include a detection module 6. This detection module 6 may be electrically connected to the controller 51 of the control module 5. The control module 5 includes a detector 61. The detector 61 is disposed in the housing space 11. Specifically, the detector 61 can detect one or more of carbon monoxide, hydrogen, smoke, temperature, spark flame, or oxygen in the energy storage module 1. The detector 61 can send the detection results to the controller 51. Based on the detection results of the detector 61, the controller 51 can control whether the release member 32 releases carbon dioxide. Therefore, by incorporating the detection module 6, various fire-related information within the energy storage module 1 can be rapidly detected, thereby enhancing the fire protection system 100's ability to prevent or detect fires. This enables the fire protection system 100 to prevent or rapidly distribute carbon dioxide at the location of a fire.

[0058] Continue to refer to Figure 1 In some embodiments, the fire suppression system 100 of the energy storage battery may further include an exhaust pressure relief module 7. The exhaust pressure relief module 7 is electrically connected to the controller 51 of the control module 5. The exhaust and pressure relief module 7 may be located outside the energy storage module 1 and communicate with the containment space 11 within the energy storage module 1. Specifically, the exhaust pressure relief module 7 may be located on the outer surface of the energy storage module 1. Since the exhaust pressure relief module 7 is communicated with the containment space 11 within the energy storage module 1, if the pressure value within the energy storage module 1 exceeds a preset pressure value, the controller 51 may control the exhaust pressure relief module 7 to release the gas in the containment space 11 into the external space of the energy storage module 1, thereby reducing the pressure within the energy storage module 1.

[0059] By incorporating the exhaust pressure relief module 7, in the event of a leak of carbon monoxide, hydrogen, and other flammable and explosive gases into the energy storage module 1, reaching a certain concentration, the carbon dioxide released by the release component 32 is diluted and replaced by the exhaust pressure relief module 7. This ensures the reliability and safety of the fire protection system 100 and provides it with fire and explosion-proof capabilities. Furthermore, the electrical connection between the controller 51 and the exhaust pressure relief module 7 further enhances the automation of the fire protection system 100. Additionally, by placing the exhaust pressure relief module 7 externally to the energy storage module 1, damage to the module is prevented in the event of a fire within the energy storage module 1, thereby ensuring the safety of using the exhaust pressure relief module 7.

[0060] For example, the exhaust pressure relief module 7 may include an exhaust pressure relief device. This device may be electrically connected to the controller 51. This allows the pressure in the energy storage module 1 to be controlled via the exhaust pressure relief device.

[0061] In some other embodiments, the exhaust pressure relief module 7 may also be disposed within the receiving space 11 of the energy storage module 1. In this way, the exhaust pressure relief module 7 can be protected by the energy storage module 1, thus increasing the service life of the exhaust pressure relief module 7.

[0062] For example, the exhaust pressure relief module 7 can open or close automatically. For example, the exhaust pressure relief module 7 can be electronic, which increases the level of automation. Alternatively, the exhaust pressure relief module 7 can be mechanical, which would eliminate the need for electrical energy.

[0063] Continue to refer to Figure 1 In some embodiments, the delivery module 4 may further include a first valve assembly 42 and a second valve assembly 43. The first valve assembly 42 is disposed on the side of the delivery pipe 41 near the storage module 2. The first valve assembly 42 is electrically connected to the controller 51. The first valve assembly 42 is used to control the connection between the storage container 21 and the release module 3. Therefore, when a fire occurs in the energy storage module 1, the controller 51 can control the first valve assembly 42 to open, thereby allowing the storage container 21 to connect with the release module 3, thus allowing the release module 3 to use the carbon dioxide in the storage container 21 to extinguish the fire. After the fire in the energy storage module 1 has been extinguished, the controller 51 can control the first valve assembly 42 to close, thereby disconnecting the storage container 21 from the release module 3, thereby reducing the waste of carbon dioxide in the storage container 21.

[0064] The second valve assembly 43 is disposed on the side of the delivery pipe 41 near the release member 32, and is electrically connected to the controller 51. The second valve assembly 43 is used to control the pressure and flow rate in the delivery pipe 41. Therefore, by controlling the pressure and flow rate in the delivery pipe 41 through the second valve assembly 43, the rate and concentration of carbon dioxide released by the release member 32 can be adjusted, allowing the fire protection system 100 to accurately release a sufficient amount of carbon dioxide to extinguish the fire according to its size, thus improving the intelligence of the fire protection system 100.

[0065] In some embodiments, the dry ice generator 31 may be disposed between the first valve assembly 42 and the second valve assembly 43. In this way, the dry ice generator 31 can first generate solid carbon dioxide, and then control the output of the solid carbon dioxide generated by the dry ice generator 31 through the second valve assembly 43.

[0066] Reference Figure 2 , Figure 2This is a schematic diagram of a fire suppression system 100 for an energy storage battery provided in some other embodiments of this disclosure. In some other embodiments, a dry ice generator 31 may be disposed between a second valve assembly 43 and a release member 32. Therefore, the flow rate of carbon dioxide supplied to the dry ice generator 31 can be controlled first via the second valve assembly 43, and then solid carbon dioxide can be generated by the dry ice generator 31. Thus, the fire suppression system 100 can adjust the output of solid carbon dioxide generated by the dry ice generator 31 as needed.

[0067] Reference Figure 3 , Figure 3 This is a schematic diagram of a fire suppression system 100 provided in some other embodiments of this disclosure. In some other embodiments, a dry ice generator 31 may be disposed between the first valve assembly 42 and the second valve assembly 43, and between the second valve assembly 43 and the release member 32. This configuration allows for more precise control of the output of solid carbon dioxide.

[0068] Continue to refer to Figure 3 In some embodiments, the first valve assembly 42 may include an on / off valve 421 and a check valve 422. Both the check valve 422 and the on / off valve 421 are disposed on the delivery conduit 41. The check valve 422 may be located between the on / off valve 421 and the storage container 21. Alternatively, the check valve 422 may be located on the side of the on / off valve 421 away from the storage container 21. By providing the check valve 422, backflow of carbon dioxide in the delivery conduit 41 can be prevented, thereby enhancing the safety of the fire protection system 100. By providing the on / off valve 421, the connection between the storage container 21 and the delivery conduit 41 can be controlled, thereby controlling whether the release member 32 needs to perform continuous release.

[0069] For example, the on / off valve 421 can be an electronic on / off valve 421. This can enhance the automation level of the fire protection system 100.

[0070] Continue to refer to Figure 3In some embodiments, the storage module 2 may further include a refrigeration unit 22, a pressure-temperature controller 51, and a pressure-temperature detector 24. The refrigeration unit 22 can be used to change the state of carbon dioxide in the storage container 21. The pressure-temperature controller 23 can be used to control the temperature and pressure in the storage container 21. The pressure-temperature detector 24 can be used to detect the temperature and pressure in the storage container 21. Therefore, when the fire protection system 100 requires liquid carbon dioxide, the pressure and temperature in the storage container 21 can be detected by the pressure-temperature detector 24, and the temperature and pressure in the storage container 21 can be changed by the refrigeration unit 22 and the pressure-temperature controller 23, so that the carbon dioxide in the storage container 21 can be converted into liquid carbon dioxide. When gaseous or solid carbon dioxide is required, the state of carbon dioxide in the storage container 21 can also be changed in the above manner. The storage module 2 can supply carbon dioxide in all three states from the same source, thereby allowing the fire protection system 100 to release carbon dioxide in different states as needed, enhancing the applicability of the fire protection system 100.

[0071] For example, the refrigeration unit 22, the pressure-temperature controller 23, and the pressure-temperature detector 24 can be mounted on the storage container 21, thereby allowing the integration of the storage module and reducing the overall size of the storage module 2.

[0072] Continue to refer to Figure 3 In some embodiments, the storage module 2 may further include a storage capacity detector 25. The storage capacity detector 25 is electrically connected to the controller 51. The storage capacity detector 25 is used to monitor the storage capacity of the storage container 21. When the storage capacity detector 25 detects that the carbon dioxide capacity in the storage container 21 is less than a preset capacity, the storage capacity detector 25 can warn the user to check for possible leaks in the storage container 21 and replenish the carbon dioxide in a timely manner. This avoids the problem of insufficient carbon dioxide in the fire protection system 100 during fire suppression, thereby ensuring the fire protection capability of the fire protection system 100.

[0073] Continue to refer to Figure 3 In some embodiments, the release member 32 may include a first release member 321 and a second release member 322. The first release member 321 is located at the edge of the battery 12. The second release member 322 is spaced apart from the first release member 321. The second release member 322 may be located between two adjacent batteries 12. When the fire suppression system 100 extinguishes a fire, the first release member 321 may form a dry ice protective layer on the edge of the battery 12 to prevent the fire from spreading. The second release member 322 may simultaneously extinguish fires on adjacent batteries 12, thereby expanding the extinguishing range of the release member 32 and thus improving the fire suppression capability of the fire suppression system 100.

[0074] The second release member 322 can also be located inside the battery 12. Therefore, when the fire protection system 100 extinguishes a fire, the second release member 322 can extinguish the fire from inside the battery 12, thereby enhancing the fire protection capability of the fire protection system 100.

[0075] The first release member 321 has a first release hole 3211. The second release member 322 has a second release hole. The first release hole 3211 and the second release hole 3221 can have the same shape and size, which can reduce costs. The first release hole 3211 and the second release hole 3221 can also have different shapes and sizes, so that the shapes and sizes of the first release hole 3211 and the second release hole 3221 can be changed according to different arrangement positions of the first release member 321 and the second release member 322. The first release member 321 and the second release member 322 in different positions can better perform different fire-fighting tasks. For example, the first release member 321 can be responsible for isolation, and the second release member 322 can be responsible for extinguishing fires.

[0076] For example, the dimensions of the first release port 3211 and the second release port 3221 can be adjustable, thereby allowing further adjustment of the output amount and form of the released carbon dioxide.

[0077] Continue to refer to Figure 3 In some embodiments, the delivery module 4 may further include a multi-way valve 433. The multi-way valve 433 includes a first port, a second port, and a third port. The first port is connected to one or more of the second and third ports. Specifically, the first port of the multi-way valve 433 may be connected only to the second port; alternatively, the first port of the multi-way valve 433 may be connected only to the third port, or the first port of the multi-way valve 433 may be connected to both the second and third ports.

[0078] The delivery conduit 41 may include a main conduit 411, a first conduit 412, and a second conduit 413. One end of the main conduit 411 is connected to the storage container 21, and the other end of the main conduit 411 is connected to a first port. One end of the first conduit 412 is connected to a first release member 321, and the other end of the first conduit 412 is connected to a second port. One end of the second conduit 413 is connected to a second release member 322, and the other end of the second conduit 413 is connected to a third port. Specifically, when the first port is connected to the second port, the first release member 321 is connected to the storage container 21 and can release carbon dioxide. When the first port is connected to both the second and third ports, both the first release member 321 and the second release member 322 are connected to the storage container 21, and both the first release member 321 and the second release member 322 can release carbon dioxide. Therefore, when the fire protection system 100 only needs to isolate the fire, it can use the first release member 321 alone. When the fire protection system 100 only needs to prevent or extinguish the fire, it can use the second release member 322 alone. When the fire protection system 100 needs to both isolate and extinguish the fire, it can use both the first release member 321 and the second release member 322 simultaneously, thereby improving the fire protection system 100's handling and firefighting capabilities under different circumstances.

[0079] Reference Figure 4 , Figure 4 This is a schematic diagram illustrating the arrangement of energy storage modules 1 and 2 provided in some embodiments of this disclosure. In some embodiments, the fire protection system 100 may include multiple energy storage modules 1. The multiple energy storage modules 1 may be arranged in multiple rows and columns. The storage module 2 may be located within the multiple energy storage modules 1. This makes it easier for the storage module 2 to supply carbon dioxide to each energy storage module 1 and relatively reduces the length of the delivery pipeline, thereby reducing costs.

[0080] Reference Figures 5 to 8 , Figures 5 to 8 This is a schematic diagram of the arrangement of energy storage module 1 and storage module 2 according to some other embodiments of the present disclosure. In some other embodiments, storage module 2 may be disposed on one side of energy storage module 1. This arrangement prevents the need to change the position of energy storage module 1.

[0081] Reference Figures 9 to 12 , Figures 9 to 12This is a schematic diagram illustrating the arrangement of energy storage module 1 and storage module 2 according to some other embodiments of this disclosure. In some other embodiments, the fire protection system 100 may include multiple storage modules 2. By providing multiple storage modules 2, the storage modules 2 can be arranged in a distributed manner, thereby mitigating the risk of a single module failure damaging the entire system and enhancing the operational reliability of the fire protection system 100.

[0082] Multiple storage modules 2 can be arranged at certain intervals along the perimeter of the storage box. This arrangement allows for a more rational layout of the delivery pipes 41 and reduces the required length of the delivery pipes 41, thereby enabling carbon dioxide to be delivered to the energy storage modules 1 at the location of the fire more quickly, thus improving the fire-fighting capability of the system 100.

[0083] In some embodiments, the fire protection system 100 may further include a housing component. The housing component is connected to the storage module 2. The housing component may be a closed box, within which the storage module 2 is located and connected to the housing component. Alternatively, the housing component may be a frame on which the storage module 2 is mounted. This allows the storage module 2 to be installed independently, thereby facilitating coordination between the storage module 2 and different energy storage modules 1.
