Description

Technical Field

[0001] This application relates to the field of energy storage equipment, specifically to an energy storage container. Background Technology

[0002] Energy storage containers are a type of energy storage device, characterized by convenient installation and transportation, high integration, small footprint, and good scalability. They are an important component of distributed energy in the field of energy storage.

[0003] Energy storage containers are generally designed for land-based use. However, when applied to ships and offshore platforms, there are significant restrictions on the spacing between adjacent containers. Existing energy storage containers face difficulties in installation and maintenance due to these large spacing limitations, requiring substantial space for both installation and repair. Utility Model Content

[0004] In view of this, the embodiments of this application are committed to providing an energy storage container to solve the technical problems of existing energy storage containers being difficult to install and arrange, difficult to repair after problems occur, requiring large intervals to install and repair the energy storage containers, and occupying a lot of space.

[0005] The first aspect of this application provides an energy storage container, comprising: The cabinet has a battery compartment inside, and a connecting door is provided on the side wall of the first end in the first direction of the cabinet. Two rows of support frames are arranged inside the battery compartment along the first direction. Battery modules are mounted on the support frames. The two rows of support frames are spaced apart in the second direction to form an inspection passage in the middle. The second direction is perpendicular to the first direction and the height direction of the energy storage container. The connecting door is connected to the inspection passage. In the second direction, the extension width of the connecting door is L(1)m, the extension width of the inspection passage is L(2)m, and L(2) / L(1) satisfies 0.65≤L(2) / L(1)≤0.85.

[0006] Another aspect of this application provides an electrical device, including the aforementioned energy storage container.

[0007] In this embodiment of the energy storage container, which is installed on a ship or offshore platform, where there are significant restrictions on the spacing between adjacent energy storage containers, when personnel need to inspect or maintain the battery modules in the energy storage container, they can enter the inspection passage through the connecting door and assemble, inspect, or maintain the battery modules on the support frames on both sides of the inspection passage. Furthermore, for this embodiment of the energy storage container, only space needs to be left outside for personnel to enter through the connecting door, without requiring additional space, effectively saving the required layout space. The width of the connecting door compared to the inspection passage is suitable, not only facilitating personnel entry into the energy storage container but also allowing for quick entry to eliminate hazards such as fires inside the container. It also effectively saves on the material cost of the connecting door, and the connecting door is less likely to collide with other structures during opening and closing. Attached Figure Description

[0021] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0022] 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, and 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.

[0023] When energy storage containers are used on ships and offshore platforms, there are significant restrictions on the spacing between adjacent containers. With existing energy storage containers having such large spacing limitations, it is difficult for personnel to perform maintenance on the battery modules from the outside of the container, as access doors are only installed on the outside. Therefore, a larger spacing between containers is necessary for maintenance, requiring more space.

[0024] like Figures 1 to 8As shown, this application provides an energy storage container for energy storage, capable of supplying power to external sources or charging using external power as needed. Specifically, as... Figure 5 As shown, the energy storage container in this embodiment of the application includes a cabinet 10 and two rows of support frames 21.

[0025] The cabinet 10 contains a battery compartment 11, and a connecting door 12 is provided on the side wall of the first end in the first direction of the cabinet 10. Two rows of support frames 21 are arranged inside the battery compartment 11 along the first direction, and battery modules 22 are mounted on the support frames 21. The two rows of support frames 21 are spaced apart in the second direction to form an inspection passage 13 in the middle. The second direction is perpendicular to the first direction and the height direction of the energy storage container. The connecting door 12 is connected to the inspection passage 13. The first and second directions of the cabinet 10 are both extension directions of the energy storage container perpendicular to the height direction, such as... Figure 1 and Figure 2 As shown, in one embodiment of this application, the first direction can be the long side extension direction of the energy storage container, and the second direction can be the short side extension direction of the energy storage container; in another embodiment of this application, the first direction can also be the short side extension direction of the energy storage container, and the second direction can be the long side extension direction of the energy storage container.

[0026] like Figure 6 As shown, in the energy storage container of this application embodiment, a plurality of mounting positions 211 are provided on the support frame 21; the energy storage container also includes a battery cluster, which includes a plurality of battery modules 22, the battery modules 22 are disposed in the mounting positions 211, and the battery modules 22 are configured to be connected in series and / or in parallel with other battery modules 22 to form a battery cluster.

[0027] Specifically, multiple battery modules 22 with similar capacity and internal resistance can be connected in series or parallel to form a battery cluster. The battery module 22 in this embodiment can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and is not limited thereto. The battery module 22 can store chemical energy and controllably convert it into electrical energy. For recyclable battery modules 22, the active materials can be activated by charging after discharge for continued use.

[0028] It is understood that in the energy storage container of the present application embodiment, the extension length of the cabinet 10 in the first direction can be greater than the extension length of the cabinet 10 in the second direction. The specific dimensions can be referred to the standard container and are not limited here.

[0029] In the energy storage container of this application embodiment, two rows of support frames 21 are arranged in the battery compartment 11 along the first direction, and the two rows of support frames 21 are spaced apart in the second direction to form an inspection passage 13 in the middle of the battery compartment 11. A connecting door 12 is provided on the side wall of the first end in the first direction of the cabinet 10, and the connecting door 12 is connected to the inspection passage 13.

[0030] In the case where the energy storage container of this application embodiment is installed on a ship or offshore platform and the spacing between adjacent energy storage containers is subject to large restrictions, when staff need to inspect and maintain the battery modules 22 in the energy storage container of this application embodiment, they can enter the inspection passage 13 after opening the connecting door 12 to assemble, inspect, or maintain the battery modules 22 on the support frames 21 on both sides of the inspection passage 13. Furthermore, for the energy storage container of this application embodiment, only space needs to be left outside for staff to enter the connecting door 12, without the need for additional space, which can effectively save the layout space required for the energy storage container of this application embodiment.

[0031] like Figure 4 and Figure 5 As shown, in the second direction, the extension width of the connecting door 12 is L(1)m, the extension width of the inspection passage 13 is L(2)m, and L(2) / L(1) satisfies 0.65≤L(2) / L(1)≤0.85.

[0032] When the ratio L(2) / L(1) of the extension width L(1)m of the connecting door 12 and the extension width L(2)m of the inspection passage 13 is less than 0.65, the connecting door 12 is narrower than the inspection passage 13, making it inconvenient for staff to enter the energy storage container through the connecting door 12. When the ratio L(2) / L(1) of the extension width L(1)m of the connecting door 12 and the extension width L(2)m of the inspection passage 13 is greater than 0.85, the extension width of the connecting door 12 is relatively large, which can easily waste the material cost of the connecting door 12 and also make the connecting door 12 prone to collision with other structures during opening and closing, thus causing the connecting door 12 to be prone to deformation.

[0033] Therefore, when the ratio L(2) / L(1) of the extension width L(1)m of the connecting door 12 and the extension width L(2)m of the inspection passage 13 satisfies 0.65≤L(2) / L(1)≤0.85, the width of the connecting door 12 is more suitable than that of the inspection passage 13. This not only makes it easier for staff to enter the energy storage container through the connecting door 12, but also allows staff to quickly enter the energy storage container to eliminate dangers such as fire inside the energy storage container. It can also effectively save the material cost of the connecting door 12. Furthermore, the connecting door 12 is less likely to collide with other structures during opening and closing. In a specific embodiment, the ratio L(2) / L(1) of the extension width L(1)m of the connecting door 12 and the extension width L(2)m of the inspection passage 13 can be selected as specific values ​​such as 0.65, 0.68, 0.72, 0.75, 0.77, 0.80, 0.82, 0.83, 0.84, 0.85, etc., and is not limited here.

[0034] Furthermore, such as Figure 5 As shown, in one embodiment of this application, in the second direction, the extension width L(2)m of the inspection path 13 satisfies 0.7m≤L(2)≤0.8m.

[0035] In the second direction, when the extension width L(2)m of the inspection passage 13 is less than 0.7m, the space inside the inspection passage 13 is small, the operating space is small, and it is not convenient for staff to turn around or squat inside the inspection passage 13, thus making it inconvenient to assemble, inspect or repair the battery modules 22 on the support frames 21 on both sides of the inspection passage 13; when the extension width L(2)m of the inspection passage 13 is greater than 0.8m, the space occupied by the inspection passage 13 is large, which affects the overall energy storage density of the energy storage container in this embodiment.

[0036] Therefore, when the extension width L(2)m of the inspection passage 13 satisfies 0.7m≤L(2)≤0.8m, the inspection passage 13 can provide sufficient operating space for the staff, facilitating their turning, squatting, and other actions within the passage. This allows for the assembly, inspection, or maintenance of the battery modules 22 on the support frames 21 on both sides of the inspection passage 13, effectively ensuring the energy storage density of the energy storage container in this embodiment. In specific embodiments, the extension width L(2)m of the inspection passage 13 can be selected from specific values ​​such as 0.7m, 0.71m, 0.72m, 0.73m, 0.75m, 0.76m, 0.77m, 0.78m, 0.79m, and 0.8m, which are not limited here.

[0037] Furthermore, such as Figure 4As shown, in one embodiment of this application, in the second direction, the extension width L(1)m of the connecting door 12 satisfies 0.9m≤L(1)≤1.1m. When the extension width L(1)m of the connecting door 12 is less than 0.9m in the second direction, the width of the connecting door 12 is relatively narrow, making it inconvenient for staff to enter the energy storage container through the connecting door 12; when the extension width L(1)m of the connecting door 12 is greater than 1.1m, the extension width of the connecting door 12 is relatively large, which easily wastes the material cost of the connecting door 12, and also makes the connecting door 12 prone to collision with other structures during opening and closing, thus causing the connecting door 12 to be easily deformed.

[0038] Therefore, when the extension width L(1)m of the connecting door 12 satisfies 0.9m≤L(1)≤1.1m, the width of the connecting door 12 is more suitable than that of the inspection passage 13. This not only facilitates the entry of personnel into the energy storage container through the connecting door 12, but also allows personnel to quickly enter the energy storage container to eliminate dangers such as fires inside the container. It also effectively saves on the material cost of the connecting door 12, and the connecting door 12 is less likely to collide with other structures during opening and closing. In specific embodiments, the extension width L(1)m of the connecting door 12 can be selected from specific values ​​such as 0.9m, 0.91m, 0.93m, 0.96m, 0.99m, 1.01m, 1.04m, 1.06m, 1.08m, and 1.1m, which are not limited here.

[0039] Specifically, in one embodiment of this application, the connecting door 12 rotates at least toward the interior of the cabinet 10 to open the inspection passage 13; the projection of the connecting door 12 along the second direction is completely located inside the projection of the inspection passage 13 along the second direction. That is, during the operation of the energy storage container in this embodiment, the operator can rotate the connecting door 12 toward the interior of the cabinet 10, thereby opening the connecting door 12 to enter the inspection passage 13 inside the energy storage container; in this way, it can be ensured that the connecting door 12, when open, will not encroach on the space outside the energy storage container, thereby improving the layout flexibility and layout density of the energy storage container in this embodiment.

[0040] Since the projection of the connecting door 12 along the second direction is completely inside the projection of the inspection passage 13 along the second direction, the width of the connecting door 12 can ensure that it will not collide with other structures inside the energy storage container when the connecting door 12 is opened to be perpendicular to the cabinet 10. This avoids deformation caused by the connecting door 12 colliding with other structures inside the energy storage container during the process of opening the connecting door 12 by the staff.

[0041] In another embodiment of this application, the connecting door 12 rotates at least outward toward the cabinet 10 to open the inspection passage 13. That is, during the operation of the energy storage container in this embodiment, the operator can rotate the connecting door 12 at least outward toward the cabinet 10 to open the inspection passage 13 inside the energy storage container. Because the connecting door 12 rotates at least outward toward the cabinet 10 to open the inspection passage 13, compared to a connecting door 12 that rotates inward toward the cabinet 10, this connecting door 12 does not occupy the internal space of the energy storage container in this embodiment. Furthermore, during the operation of the connecting door 12, it will not collide with other structures inside the energy storage container, causing deformation. Moreover, compared to opening inward, opening outward makes it easier for operators to exit the energy storage container. If an operator is inside the energy storage container and a fire or explosion occurs, the operator can more naturally and effortlessly push open the connecting door 12 to escape.

[0042] It is understood that, further, in one embodiment of this application, the connecting door 12 can rotate toward the inside of the cabinet 10 and toward the outside of the cabinet 10 to open the inspection passage 13. In this way, the staff can open the connecting door 12 as needed and in the desired manner, thereby improving the flexibility of opening the connecting door 12.

[0043] In another embodiment of this application, the connecting door 12 is translated along the second direction to open the inspection passage 13. Since the connecting door 12 in this embodiment can be translated along the second direction to open the inspection passage 13, it does not occupy the internal or external space of the energy storage container, minimizing space occupation in the open state. This makes it suitable for applications where the external or internal space of the energy storage container is extremely limited. Furthermore, the connecting door 12 is more stable in the open state and is less susceptible to swaying due to external wind forces, ship swaying, etc., thus providing higher operational stability and long-term reliability.

[0044] like Figure 6 and Figure 7 As shown, in one embodiment of this application, the battery module 22 is provided with a wiring terminal 221, and a connecting wire harness is plugged into the wiring terminal 221. The connecting wire harness connects the battery modules 22 in series and / or in parallel, and the wiring terminals 221 are all located on the side facing the inspection passage 13.

[0045] In the energy storage container of this application embodiment, battery modules 22 are connected in series and / or in parallel through connecting harnesses to form a battery cluster. The battery modules 22 in the battery cluster can uniformly supply power to the outside or receive external power for charging to perform energy storage. Specifically, the connecting harness is plugged into the terminal 221 of the battery module 22 to electrically connect with the battery module 22.

[0046] Since the wiring terminals 221 on the battery module 22 are all located on the side facing the inspection passage 13, it is convenient for staff to directly plug, unplug, and tighten the connecting wires within the inspection passage 13. This reduces the difficulty of assembling, inspecting, or repairing the battery module 22, significantly saving maintenance time and reducing labor intensity. At the same time, the uniform layout of the wiring terminals 221 on all battery modules 22 reduces the possibility of misoperation, thereby improving the accuracy and safety of maintenance operations.

[0047] Furthermore, such as Figure 5 As shown, in one embodiment of this application, an equipment compartment 14 is formed inside the cabinet 10, and the battery compartment 11 and the equipment compartment 14 are isolated from each other by a partition wall 15; a plurality of high-voltage control boxes 23 are provided on the support frame 21; a combiner device 31 is provided inside the equipment compartment 14, and the combiner device 31 is configured to be electrically connected to the battery module 22 through the high-voltage control box 23, and the connecting wire harness between the combiner device 31 and the high-voltage control box 23 passes through the partition wall 15.

[0048] During the operation of the energy storage container in this embodiment, a combiner device 31 is installed in the equipment compartment 14. The combiner device 31 is electrically connected to the battery module 22 through the high-voltage control box 23, thereby forming a battery cluster that can uniformly supply power to the outside or receive external power for charging to store energy. Since the battery compartment 11 and the equipment compartment 14 are isolated from each other by a partition wall 15, and the connecting harness between the combiner device 31 and the high-voltage control box 23 passes through the partition wall 15, the partition wall 15 can effectively prevent flames, high temperatures, or harmful gases from spreading to the equipment compartment 14 in a short time in the event of thermal runaway, fire, or explosion of the battery module 22 in the battery compartment 11, ensuring that the equipment in the equipment compartment 14 continues to operate normally for a period of time, thereby improving the overall safety and reliability of the energy storage container in this embodiment. Furthermore, placing the combiner device 31 in a separate equipment compartment 14 can effectively optimize wiring and facilitate the debugging and maintenance of the combiner device 31.

[0049] Furthermore, such as Figure 5 and Figure 6As shown, in one embodiment of this application, a heat exchange pipeline is provided inside the battery module 22; a heat exchange device 41 is provided inside the equipment compartment 14, and the heat exchange device 41 is connected to the heat exchange pipeline inside the battery module 22 to exchange heat between the battery module 22 and the heat exchange liquid. During the operation of the energy storage container in this embodiment, the heat exchange device 41 inside the equipment compartment 14 can be connected to the heat exchange pipeline inside the battery module 22 to exchange heat between the battery module 22 and the heat exchange liquid, ensuring that the battery module 22 can operate within a suitable operating temperature range; when the temperature of the battery module 22 is low and the internal material activity is low, the battery module 22 can be heated to improve its charging and discharging efficiency; when the temperature of the battery module 22 is high, the battery module 22 can be cooled in a timely manner to extend its operating time. The long cycle life of the battery module 22 ensures the operational safety of the battery module 22. Furthermore, since the heat exchange equipment 41 is located in the equipment compartment 14, and the battery compartment 11 and the equipment compartment 14 are isolated from each other by the partition wall 15, in the event of thermal runaway, fire, or explosion of the battery module 22 in the battery compartment 11, it effectively prevents the spread of flames, high temperatures, or harmful gases to the equipment compartment 14 in a short period of time, ensuring that the heat exchange equipment 41 continues to operate normally for a period of time, reducing the probability of thermal runaway propagation of the battery module 22, and improving the overall safety and reliability of the energy storage container in this embodiment of the application.

[0050] Furthermore, such as Figure 6 As shown, in one embodiment of this application, the battery module 22 is provided with a heat exchange inlet 222 and a heat exchange outlet 223, and the heat exchange device 41 is connected to the heat exchange inlet 222 and the heat exchange outlet 223 through a heat exchange pipeline; the heat exchange inlet 222 and the heat exchange outlet 223 are both located on the side facing the inspection passage 13.

[0051] During the operation of the energy storage container in this embodiment, the heat exchange equipment 41 in the equipment compartment 14 can drive the heat exchange liquid to enter the heat exchange inlet 222 of the battery module 22 along the heat exchange pipeline, and then flow out from the heat exchange outlet 223 of the battery module 22 and back to the heat exchange equipment 41 through the heat exchange pipeline. Since the heat exchange inlet 222 and heat exchange outlet 223 on the battery module 22 are both located on the side facing the inspection passage 13, it is convenient for staff to inspect or repair the heat exchange pipeline and the heat exchange inlet 222 and heat exchange outlet 223 on the battery module 22 within the inspection passage 13. Staff can easily check for heat exchange liquid leaks in the heat exchange pipeline, which greatly saves maintenance time, reduces labor intensity, and improves maintenance efficiency.

[0052] Specifically, such as Figure 6As shown, in one embodiment of this application, the heat exchange pipeline includes an inlet pipeline 421 and a return pipeline 422. The heat exchange device 41 is configured to drive the heat exchange liquid from the heat exchange device 41 through the inlet pipeline 421 into the heat exchange inlet 222 of the battery module 22, and to allow the heat exchange liquid to flow from the heat exchange outlet 223 of the battery module 22 back to the heat exchange device 41 through the return pipeline 422. That is, during the operation of the energy storage container of this embodiment, the heat exchange device 41 can drive the heat exchange liquid to enter the heat exchange inlet 222 of the battery module 22 along the inlet pipeline 421, and then flow out from the heat exchange outlet 223 of the battery module 22 and return to the heat exchange device 41 through the return pipeline 422. By dividing the heat exchange pipeline into an inlet pipeline 421 and a return pipeline 422, it can be ensured that each battery module 22 can receive sufficient heat exchange, avoiding the occurrence of poor heat exchange and the battery module 22 being unable to operate within the appropriate operating temperature range.

[0053] Furthermore, such as Figure 6 As shown in one embodiment of this application, each of the two support frames 21 is provided with mounting positions 211 arranged in an array along the first direction and the height direction; the liquid inlet pipe 421 includes a primary liquid inlet pipe 4211, a secondary liquid inlet pipe 4212 and a tertiary liquid inlet pipe 4213; the liquid return pipe 422 includes a primary liquid return pipe 4221, a secondary liquid return pipe 4222 and a tertiary liquid return pipe 4223; the primary liquid inlet pipe 4211 and / or the primary liquid return pipe 4221 extend at least partially along the first direction; the secondary liquid inlet pipe 4212 and / or the secondary liquid return pipe 4222 extend at least partially along the height direction; and the tertiary liquid inlet pipe 4213 and / or the tertiary liquid return pipe 4223 extend at least partially along the first direction.

[0054] In the energy storage container of this application embodiment, the heat exchange device 41 can drive the heat exchange liquid to flow into the primary inlet pipe 4211. The heat exchange liquid flowing into the primary inlet pipe 4211 can flow to each secondary inlet pipe 4212. The heat exchange liquid in each secondary inlet pipe 4212 can flow to each connected tertiary inlet pipe 4213, and then flow to the heat exchange inlet 222 of each battery module 22. Similarly, the heat exchange liquid flowing out from the heat exchange inlet 222 of each battery module 22 can flow to each connected tertiary return pipe 4223. The heat exchange liquid in each tertiary return pipe 4223 can flow to each connected secondary return pipe 4222. The heat exchange liquid in each secondary return pipe 4222 converges to the primary return pipe 4221, and then flows back to the heat exchange device 41.

[0055] Since the primary inlet pipe 4211 and / or the primary return pipe 4221 extend at least partially along the first direction; the secondary inlet pipe 4212 and / or the secondary return pipe 4222 extend at least partially along the height direction; and the tertiary inlet pipe 4213 and / or the tertiary return pipe 4223 extend at least partially along the first direction, the layout of the inlet pipe 421 and the return pipe 422 can be effectively optimized. This not only facilitates the uniform flow of the heat exchange liquid and ensures that each battery module 22 receives sufficient heat exchange, avoiding poor heat exchange, but also facilitates the installation, debugging, and partial maintenance and replacement of the inlet pipe 421 and the return pipe 422.

[0056] like Figure 8 As shown, in one embodiment of this application, a fire-fighting liquid nozzle 51 is provided in the battery compartment 11; a fire-fighting liquid driving device 52 is provided in the equipment compartment 14, and the fire-fighting liquid driving device 52 is connected to the fire-fighting liquid nozzle 51 through a fire-fighting pipeline 53.

[0057] In the energy storage container of this application embodiment, when the battery module 22 in the battery compartment 11 experiences thermal runaway, fire, or explosion, the fire-fighting liquid driving device 52 drives the fire-fighting liquid to flow through the fire-fighting pipeline 53 to the fire-fighting liquid nozzle 51, and then sprays it into the battery compartment 11, thereby cooling and extinguishing the fire in the battery compartment 11, effectively controlling the initial fire, preventing its spread and expansion, avoiding the chain reaction of deflagration in the battery module 22, and improving the operational safety of the energy storage container of this application embodiment.

[0058] Since the fire-fighting liquid-driven device 52 is located in the equipment compartment 14, and the battery compartment 11 is isolated from the equipment compartment 14 by the partition wall 15, in the event of thermal runaway, fire, or explosion of the battery module 22 in the battery compartment 11, the spread of flames, high temperatures, or harmful gases to the equipment compartment 14 in a short period of time is effectively prevented. This ensures that the fire-fighting liquid-driven device 52 continues to operate normally, spraying fire-fighting liquid into the battery compartment 11, thereby improving the overall safety and reliability of the energy storage container in this embodiment. It is understood that the aforementioned fire-fighting liquid can be a fire extinguishing agent such as trichloropropane or liquid carbon dioxide, and there is no specific limitation.

[0059] Specifically, in one embodiment of this application, at least one of a combustible gas sensor, a smoke sensor, and a temperature sensor is provided in the battery compartment 11. The combustible gas sensor, smoke sensor, and temperature sensor are all signal-connected to the fire-fighting liquid-driven device 52; the fire-fighting liquid-driven device 52 operates based on the signals from at least one of the combustible gas sensor, smoke sensor, and temperature sensor.

[0060] In this embodiment, the battery compartment 11 is equipped with at least one of a combustible gas sensor, a smoke sensor, and a temperature sensor. The combustible gas sensor can determine whether a fire has occurred in the battery compartment 11 by acquiring the combustible gas concentration in the battery compartment 11. The smoke sensor can determine whether a fire has occurred in the battery compartment 11 by acquiring the smoke concentration in the battery compartment 11. The temperature sensor can determine whether a fire has occurred in the battery compartment 11 by acquiring the ambient temperature in the battery compartment 11. The fire-fighting liquid driving device 52 can automatically drive the fire-fighting liquid to spray into the battery compartment 11 in the event of a fire, based on the feedback signal from at least one of the combustible gas sensor, smoke sensor, and temperature sensor, thereby cooling and extinguishing the fire in the battery compartment 11, effectively controlling the initial fire, preventing its spread and expansion, and significantly improving the effectiveness and reliability of the fire protection system of the energy storage container in this embodiment.

[0061] It is understandable that the aforementioned combustible gas sensors, smoke sensors, and temperature sensors can be used individually or in combination to improve the sensitivity of fire detection.

[0062] Furthermore, in one embodiment of this application, an internal early warning sensor is provided inside the battery module 22, and a fire inlet is provided; the internal early warning sensor is signal-connected to the fire-fighting liquid-driven device 52; the fire-fighting liquid-driven device 52 is connected to the fire inlet on the battery module 22 through the fire-fighting pipeline 53.

[0063] In this embodiment, the battery module 22 can be equipped with an internal early warning sensor to detect whether abnormal temperature or pressure rise, such as thermal runaway, occurs inside the battery module 22. At the same time, each battery module 22 is also equipped with a fire inlet. In this way, when preliminary thermal runaway occurs inside any battery module 22, its internal early warning sensor will first alarm, and the fire-fighting liquid driving device 52 can directly drive the fire-fighting liquid to flow to the fire inlet on the battery module 22 to achieve targeted fire-fighting treatment, extinguish the fire in its infancy, greatly improve fire-fighting efficiency, and reduce secondary damage to other equipment in the entire battery compartment 11 caused by the spraying of fire extinguishing agents.

[0064] In one embodiment of this application, at least one intake fan and at least one exhaust fan are provided on the side wall and / or top wall of the battery compartment 11; the intake fan is configured to deliver outside gas into the battery compartment 11; the exhaust fan is configured to exhaust the gas inside the battery compartment 11 to the outside. Specifically, during the operation of the energy storage container in this embodiment, the intake fan and exhaust fan can realize the spatial flow inside and outside the energy storage container, which can remove the waste heat generated during battery operation, maintain a stable ambient temperature inside the battery compartment 11, help delay the aging of the battery module 22 and eliminate safety hazards; and, after a fire accident, the exhaust fan can efficiently remove the residual smoke and toxic gases inside the battery compartment 11, facilitating post-accident handling by personnel.

[0065] Specifically, such as Figure 5 As shown, in one embodiment of this application, the equipment compartment 14 is divided into a manifold compartment 141, a heat exchange compartment 142, and a fire compartment 143 by partitions 144; the manifold device 31 is disposed in the manifold compartment 141; the heat exchange device 41 is disposed in the heat exchange compartment 142; the fire-fighting liquid-driven device 52 is disposed in the fire compartment 143; the cabinet 10 is provided with a manifold cabinet door 161 for opening the manifold compartment 141, a heat exchange cabinet door 162 for opening the heat exchange compartment 142, and a fire cabinet door 163 for opening the fire compartment 143.

[0066] By dividing the equipment compartment 14 into three sub-compartments—a manifold compartment 141, a heat exchange compartment 142, and a fire-fighting compartment 143—using partitions 144, the manifold equipment 31, the fire-fighting liquid-driven equipment 52, and the heat exchange equipment 41 can be further isolated, effectively preventing mutual interference between them. Personnel can adjust and maintain the manifold equipment 31, the fire-fighting liquid-driven equipment 52, and the heat exchange equipment 41 from the outside of the cabinet 10 through the manifold cabinet door 161, the heat exchange cabinet door 162, and the fire-fighting cabinet door 163. The independent cabinet doors allow personnel to access specific equipment quickly and selectively. It is understood that the partitions 144 can have a different structure than the aforementioned isolation walls, or they can have the same structure as the aforementioned barrier wall 15.

[0067] like Figures 1 to 3As shown, in one embodiment of this application, the manifold 141, heat exchange chamber 142, and fire compartment 143 are arranged along a second direction, with the fire compartment 143 located between the manifold 141 and the fire compartment 143; the manifold cabinet door 161 is located on the side wall of the cabinet 10 adjacent to the manifold 141 in the second direction; the fire compartment door 163 is located on the side wall of the cabinet 10 at the second end in the first direction; the heat exchange cabinet door 162 includes an assembly cabinet door 1621 and a maintenance cabinet door 1622, with the assembly cabinet door 1621 located on the side wall of the cabinet 10 at the second end in the first direction and the maintenance cabinet door 1622 located on the side wall of the cabinet 10 adjacent to the heat exchange chamber 142 in the second direction.

[0068] Understandably, since the fire-fighting pipeline 53 is located in the middle of the battery compartment 11, and the fire-fighting compartment 143 is located between the manifold 141 and the fire-fighting compartment 143, the required path for the fire-fighting liquid to flow from the fire-fighting pipeline 53 to the fire-fighting liquid nozzle 51 can be effectively shortened. Furthermore, since the heat exchange cabinet door 162 includes an assembly cabinet door 1621 and a maintenance cabinet door 1622, the assembly cabinet door 1621 is located on the side wall of the cabinet body 10 at the second end in the first direction, and the maintenance cabinet door 1622 is located on the side wall of the cabinet body 10 adjacent to the heat exchange compartment 142 in the second direction. The assembly cabinet door 1621 is larger in size, which facilitates the overall hoisting and placement of the heat exchange equipment 41, while the maintenance cabinet door 1622 is smaller in size, which facilitates the staff to quickly inspect and maintain the pumps, valves, and other components of the heat exchange equipment 41 on a daily basis.

[0069] Furthermore, in one embodiment of this application, the equipment compartment 14 is equipped with an operation panel or display screen, etc. The operation panel is located on one side of the second end of the junction device 31 in the first direction and is configured to be signal-connected to at least one of the junction device 31, the heat exchange device 41, and the fire-fighting liquid-driven device 52. The cabinet 10 is also provided with an operation panel door on the side wall of the second end in the first direction to open the operation panel. The operation panel allows personnel to monitor and control the various devices of the energy storage container from the outside of the energy storage container in this embodiment of the application, without having to enter the battery compartment 11 or open the various doors of the equipment compartment 14, effectively improving inspection efficiency. The display screen can be signal-connected to the camera or other equipment in the battery compartment 11, facilitating personnel to observe the internal status of the energy storage container in real time.
