Description

[Technical field]

[0001] This application claims priority to Korean Patent Application No. 10-2022-0068539, filed on June 3, 2022, the entire contents of which are incorporated herein by reference in their entirety in the specification and drawings.

[0002] The present invention relates to a battery, and more particularly to a battery container in which a plurality of battery modules are housed inside a container-shaped housing so as to be capable of storing energy, and an energy storage system including the battery container. [Background technology]

[0003] In recent years, as issues such as power shortages and environmentally friendly energy have come to the fore, energy storage systems (ESS) for storing generated electricity have been drawing more attention. Typically, the use of such ESS makes it easy to build a power management system such as a smart grid system, making it easy to adjust the supply and demand of electricity in a specific region or city. In addition, as electric vehicles are becoming more commercially available, such ESS can also be applied to electric charging stations for charging electric vehicles.

[0004] The ESS may be configured in various forms, typically including one or more battery containers. In this case, the battery container may include a plurality of battery modules connected in series and / or parallel to each other. Here, the plurality of battery modules may be housed inside the battery container via a rack frame or a separate fixing structure.

[0005] Battery containers used in ESS often contain multiple battery modules inside to increase capacity and output. Furthermore, multiple battery modules may be densely packed together to increase the energy density of the battery container.

[0006] However, when a large number of battery modules are densely packed in a small space, the battery container is vulnerable to accidents such as fire and explosion. In particular, if an event such as a fire occurs in one battery module due to thermal runaway, the fire may spread to other battery modules included in the battery container. In this case, the entire battery container (the battery container in which the event such as a fire occurs) may be damaged to an unusable state. In addition, such a fire in a battery container may cause not only physical damage to the battery container, but also human damage to surrounding workers and users. Furthermore, the unusability of a battery container included in an ESS may cause unexpected damage to homes, factories, and the like that receive power from the ESS. In addition, since an ESS may include multiple battery containers, a fire in a specific battery container may spread to other battery containers, resulting in greater damage.

[0007] In an attempt to prevent such problems, various technologies have been proposed or applied. A representative example is a water injection system that injects or supplies a fire extinguishing liquid, particularly water, to the entire interior of a battery container or to a specific battery module when a fire occurs in the battery container. However, when such a water injection system is applied to a battery container, many problems arise, such as a complicated internal structure of the battery container, a reduced energy density, and increased costs. Furthermore, in the case of a fire prevention system that injects water from the interior of the battery container, for example, from the top of the battery container, there is a risk that the entire battery container will become unusable. In addition, water that is directly injected into the battery modules and used to put out a fire becomes contaminated water, causing environmental problems, which can result in significant economic or social damage. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been devised to solve the above problems, and aims to provide a battery container that can effectively prevent the spread of fire, and an energy storage system including the battery container.

[0009] The technical problems to be solved by the present invention are not limited to the problems mentioned above, and other problems will be clearly understood by those skilled in the art from the following description of the invention. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, a battery container according to one aspect of the present invention includes a container housing having an internal space formed therein, a plurality of battery modules accommodated in the internal space of the container housing and stacked vertically to form a module stack, the module stacks being arranged in a horizontal direction, and a blocking partition configured to be interposed between at least some of the module stacks and separate the spaces between the module stacks.

[0011] Here, the isolation bulkhead may have an upper end fixed to an upper side of the container housing and a lower end fixed to a lower side of the container housing.

[0012] The isolation partition wall may include a plate portion disposed between two adjacent module stacks in an upright manner such that both sides of the plate portion face different module stacks.

[0013] The plate portion may include two plates spaced apart from each other.

[0014] The blocking bulkhead may also include a first pillar portion supporting the plate portion.

[0015] The isolation barrier may also include a first mounting portion configured to support the battery module.

[0016] In addition, the isolation partition may include two or more isolation partitions, and the battery container may further include a support wall disposed between the two isolation partitions and configured to support the battery module together with the isolation partitions.

[0017] Additionally, the front and rear ends of the isolation bulkhead may contact the front and rear inner surfaces of the container housing, respectively.

[0018] The isolation partition wall may have an inclined surface that is inclined toward the module stack as it goes outward in the front-rear direction.

[0019] Also, an energy storage system according to another aspect of the present invention includes a battery container according to an aspect of the present invention. Effect of the Invention

[0020] According to one aspect of the present invention, the safety of a battery container can be improved.

[0021] In particular, according to one aspect of the present invention, the spread of fire between multiple battery modules inside a battery container can be effectively prevented or suppressed.

[0022] Furthermore, according to one aspect of the present invention, a configuration for effectively preventing the spread of fire can be provided with a relatively simple structure, thereby reducing the manufacturing cost of the battery container, ensuring reliability in quality, and increasing productivity.

[0023] In addition, according to one aspect of the present invention, by reducing the weight of the battery container, it is possible to easily transport the battery container and install an energy storage system using the battery container.

[0024] In particular, according to one aspect of the present invention, the spread of a fire can be effectively suppressed or delayed even if a water injection system or a fire suppression system (FSS) for preventing the spread of a fire is not included in the battery container.

[0025] Therefore, it is possible to prevent problems such as a complicated structure or increased weight and cost due to a water injection system or a fire suppression system, etc. In addition, according to one aspect of the present invention, it is possible to prevent problems such as environmental pollution caused by water directly injected into a battery module where a fire has occurred being discharged.

[0026] In addition, various other additional effects can be achieved by many embodiments of the present invention. The various effects of the present invention will be described in detail in each embodiment, but the description of the effects that are easily understood by those skilled in the art will be omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms and words used in the present specification and claims are not to be construed as being limited to their ordinary and dictionary meanings, but are to be construed as having meanings and concepts corresponding to the technical ideas of the present invention, in accordance with the principle that the inventors themselves can appropriately define the concepts of terms in order to best describe the invention.

[0030] Therefore, it should be understood that the embodiment described in this specification and the configurations shown in the drawings are merely the most preferred embodiment of the present invention and do not represent the entire technical idea of ​​the present invention, and therefore there may be various equivalents and modifications that can be substituted therefor at the time of this application.

[0031] FIG. 1 is a perspective view that shows a schematic configuration of a portion of a battery container according to one embodiment of the present invention.

[0032] Referring to FIG. 1, a battery container according to the present invention includes a container housing 100, a battery module 200, and an isolation barrier 300.

[0033] The container housing 100 may have an internal space. More specifically, the container housing 100 may include six plates, i.e., an upper plate 101, a lower plate 102, a left plate 103, a right plate 104, a front plate (not shown), and a rear plate (not shown), to form the internal space. In particular, the container housing 100 may be formed in a substantially rectangular parallelepiped shape.

[0034] For example, in the embodiment of FIG. 1, the container housing 100 includes an upper plate 101, a lower plate 102, a left plate 103, and a right plate 104. Here, the container housing 100 may further include a front plate and a rear plate, but in FIG. 1, the front plate and the rear plate are removed in order to more clearly show the internal components. In addition, the front plate and the rear plate may include one or more doors to open the internal space of the container housing 100, or may be entirely configured as a door. In addition, although the term "plate" is used for the multiple plates constituting the container housing 100, the surfaces are not limited to those having a completely flat shape. That is, the multiple surfaces constituting the container housing 100 may have a partially bent or curved shape, or may have a reinforcing structure such as a rib or an overlapping structure. For example, a reinforcing member may be provided at the corners or center of the container housing 100.

[0035] The container housing 100 is an exterior material of a battery container, and may be made of a highly rigid material and structure to protect various components housed in the internal space, particularly the battery module 200. For example, the container housing 100 may be made of a metal material such as steel.

[0036] However, the present invention is not limited to such a specific shape or material of the container, and various container housings 100 known at the time of filing of the present application may be used in the present invention.

[0037] The battery module 200 may be accommodated in an internal space of the container housing 100. In particular, a plurality of battery modules 200 may be included in the battery container in order to increase capacity and / or output. The plurality of battery modules 200 may be electrically connected in series and / or in parallel via connecting members such as bus bars or cables.

[0038] At least some of the battery modules 200 may be stacked in the vertical direction to form a module stack. That is, the module stack may be configured to be formed by stacking two or more battery modules 200 in the vertical direction (Z-axis direction in the drawing). For example, 13 battery modules 200 may be stacked in the vertical direction to form one module stack.

[0039] Also, a plurality of module stacks may be arranged in the horizontal direction. That is, a plurality of battery modules 200 may be divided into several groups, and a separate module stack may be formed for each group. The plurality of module stacks may be arranged in the horizontal direction. For example, referring to FIG. 1, a battery container may include 14 module stacks S1 to S14, and the 14 module stacks S1 to S14 may be arranged at a predetermined distance apart in the left-right direction (X-axis direction in the drawing). In this case, each module stack S1 to S14 may include 13 battery modules 200. However, it is needless to say that the number of stacked battery modules 200 and the number of module stacks S1 to S14 arranged in the horizontal direction may be variously set according to many conditions or situations, such as the specifications and mounting purposes of the battery container, and the specifications, characteristics, and types of the battery modules 200.

[0040] The blocking partition 300 may be interposed between at least some of the module stacks among the plurality of module stacks. For example, referring to Fig. 1, 14 module stacks S1 to S14 are arranged from left to right, and the blocking partition 300 may be interposed between the second stack S2, which is the second module stack from the left, and the third stack S3, which is the third module stack from the left, as indicated by F2. The blocking partition 300 may also be interposed in spaces between other module stacks, such as between the fourth stack S4, which is the fourth module stack from the left, and the fifth stack S5, which is the fifth module stack, as indicated by F4.

[0041] The isolating partition 300 may be configured to be interposed between the adjacent module stacks in this manner to separate the space between the adjacent module stacks. For example, in the embodiment of Fig. 1, the isolating partition 300 (F2) may be configured to separate the space between the adjacent second stack S2 and third stack S3.

[0042] In particular, the isolation bulkhead 300 may be configured to prevent the spread of fire in the space between adjacent module stacks. For example, the isolation bulkhead 300 (F2) interposed between the second stack S2 and the third stack S3 may be configured to separate the space in which the second stack S2 is housed from the space in which the third stack S3 is housed, to prevent the transfer of fire between the two spaces.

[0043] The isolation bulkhead 300 may be constructed of a high melting point and high strength material sufficient to withstand fire, high temperatures, etc. For example, the isolation bulkhead 300 may include a metallic material, such as a steel material.

[0044] According to such an embodiment of the present invention, even if a fire occurs in a specific module stack, the fire can be effectively prevented from spreading to other adjacent module stacks. For example, in the embodiment of Fig. 1, even if a fire occurs in the second stack S2, the flame can be prevented from moving toward the third stack S3, and the spread of the fire between the module stacks can be prevented. Therefore, even without a separate water injection system or fire suppression system, the spread of the fire between the module stacks included in the battery container can be effectively prevented.

[0045] The isolation bulkhead 300 may have an end fixed to the inner surface of the container housing 100. This will be described in more detail with reference to FIG.

[0046] FIG. 2 is a perspective view that illustrates a schematic configuration of the embodiment of FIG. 1 with the battery module 200 removed.

[0047] 2, the isolation partition 300 may have an upper end coupled and fixed to an upper surface of the inner surface of the container housing 100 as shown by A1, and a lower end coupled and fixed to a lower surface of the inner surface of the container housing 100 as shown by A2.

[0048] According to this embodiment of the present invention, the isolation bulkhead 300 contacts between the upper surface (upper inner surface) and the lower surface (lower inner surface) of the container housing 100, thereby reducing or eliminating the gap between the isolation bulkhead 300 and the inner surface of the container housing 100. Therefore, the flame blocking performance of the isolation bulkhead 300 is further improved.

[0049] In addition, according to the present embodiment, since the isolation bulkhead 300 supports the upper plate 101 and the lower plate 102 of the container housing 100, the structural rigidity of the isolation bulkhead 300 can be improved. In particular, in the present embodiment, sagging or deformation of the upper plate 101 of the container housing 100 can be prevented.

[0050] Here, the isolation bulkhead 300 and the container housing 100 may be connected and fixed in various ways. For example, the isolation bulkhead 300 and the container housing 100 may be configured in such a manner that at least a portion of them are integrated together. In this case, the isolation bulkhead 300 and at least a portion of the container housing 100 may be manufactured from the beginning in an integrated form so as not to be separated using the same material. Alternatively, the isolation bulkhead 300 and the container housing 100 may be connected in various ways such as a bolting method, a welding method, a fitting method, etc.

[0051] In particular, the blocking partition 300 may be configured such that a portion that contacts the inner surface of the container housing 100, i.e., a contact surface, extends long. For example, the upper end of the blocking partition 300 may contact the upper inner surface (upper surface) of the container housing 100, and the contact portion may extend long in the front-rear direction (Y-axis direction in the drawing). Furthermore, the upper end of the blocking partition 300 may contact the upper surface of the container housing 100 continuously in the Y-axis direction from the front end to the rear end. Also, the lower end of the blocking partition 300 may contact the lower inner surface (lower surface) of the container housing 100. And, such a lower contact portion may also extend long in the front-rear direction. Furthermore, the lower end of the blocking partition 300 may contact the lower surface of the container housing 100 continuously in the Y-axis direction from the front end to the rear end.

[0052] According to this embodiment of the present invention, the gap between the isolation bulkhead 300 and the container housing 100 can be reduced or eliminated. Therefore, when a fire occurs in a specific module stack, the flame can be more reliably prevented from moving to the gap between the isolation bulkhead 300 and the container housing 100 and spreading to other module stacks. Also, according to this embodiment, it is possible to prevent high-temperature vent gas, etc. from moving through the gap between the isolation bulkhead 300 and the container housing 100. Therefore, it is possible to prevent damage to other module stacks, thermal runaway transition, or fire caused by high-temperature vent gas, etc. Also, according to this embodiment, the supporting force of the isolation bulkhead 300 with respect to the container housing 100 is improved. Therefore, the structural strength of the battery container can be further improved.

[0053] Fig. 3 is an enlarged view of a portion of a battery container according to an embodiment of the present invention. For example, Fig. 3 is an enlarged view of a portion B1 of Fig. 2. In particular, in Fig. 3, some components are shown in a transparent form to more clearly show the configuration. In the following drawings, some components will be shown in a transparent form as necessary.

[0054] 1 to 3, the isolation bulkhead 300 may include a plate portion 310. The plate portion 310 may be formed in a substantially plate-like shape and may have two flat surfaces on both sides. The plate portion 310 may be disposed between two adjacent module stacks in an upright manner such that both sides of the plate portion 310 face different module stacks. For example, when module stacks are located on the left and right sides of the isolation bulkhead 300, both sides of the plate portion 310 may be located on the left and right sides. Thus, the left side of the plate portion 310 may face the module stack on the left side, and the right side of the plate portion 310 may face the module stack on the right side.

[0055] Meanwhile, the plate part 310 may be generally plate-shaped. However, the present invention is not limited to this. For example, the plate part 310 may be partially curved or may have projections or protrusions.

[0056] According to this embodiment of the present invention, effective fire protection between module stacks is possible without increasing the volume and weight of the battery container due to the isolation barrier 300. In particular, according to this embodiment, since the isolation barrier 300 is not formed thick in the horizontal arrangement direction of the module stacks, it is possible to effectively suppress the transmission of flame or gas while reducing the gap between the module stacks.

[0057] In the isolation partition 300 of the battery container according to the present invention, the plate portion 310 may include two plates, which will be described in more detail with reference to FIGS.

[0058] 4 is an exploded perspective view of the configuration of FIG. 3, and FIG. 5 is a cross-sectional view taken along line C1-C1' of FIG.

[0059] 4 and 5, each isolation bulkhead 300 may be provided with two plate portions 310. The two plate portions 310 may be arranged to face each other in the horizontal direction (X-axis direction) in which a plurality of module stacks are arranged. Furthermore, the two plate portions 310 may be spaced apart from each other by a predetermined distance. That is, the two plate portions 310 may be spaced apart from each other by a predetermined distance in the X-axis direction. Therefore, a space as indicated by V1 in the drawings may be formed between the two plate portions 310.

[0060] According to this embodiment of the present invention, the two plate parts 310 constitute different parts of the partition wall, and thus a double fire blocking space can be formed. In addition, since the two plate parts 310 are not integrated, heat transfer between the two plate parts 310 is suppressed. Furthermore, when the two plate parts 310 are spaced apart from each other to form a space therebetween, the heat insulating effect between the two plate parts 310 is further improved by an air layer or the like. Furthermore, by reducing the weight of each isolation partition 300, the weight of the entire battery container is reduced. This is therefore more advantageous for transportation and installation of the battery container.

[0061] In addition, according to the present embodiment, the space between the two plate portions 310 can absorb the deformation of the plate portion 310. In particular, when gas or fire occurs in a specific module stack, the internal pressure may increase in the space in which the module stack (the module stack in which the gas or fire occurs) is housed. Then, due to this increase in internal pressure, pressure may be applied to the plate portion 310 directly facing the module stack. At this time, the plate portion 310 may be pressed against the portion in which the space is formed as shown by V1 in FIG. 5. Therefore, even if any of the plate portions 310 is deformed by the application of pressure, the overall position of the isolation partition wall 300 is maintained. In addition, the other plate portions 310 provided in the isolation partition wall 300 are not damaged or deformed. That is, the space between the two plate portions 310 can be a space that buffers the deformation of the plate portion 310 due to the increase in internal pressure.

[0062] Fig. 6 is an exploded perspective view showing a schematic configuration of a portion of a battery container according to another embodiment of the present invention. Fig. 6 shows a modified form of the isolation bulkhead 300, particularly the plate portion 310, shown in Fig. 4. In various embodiments included in this specification, including this embodiment, detailed descriptions of parts that can be applied in the same or similar manner to the descriptions of other embodiments will be omitted, and differences will be mainly described.

[0063] Referring to FIG. 6, the plate portion 310 in the isolation bulkhead 300 may be configured with an end portion bent as shown by D1. For example, the lower end portion of the plate portion 310 may be configured with a bent portion. Such a bent portion of the lower end may contact the lower inner surface, i.e., the bottom surface, of the container housing 100. Furthermore, the lower surface of the bent portion of the lower end of the plate portion 310 may be fixed in contact with the bottom surface of the container housing 100. The upper end portion of the plate portion 310 may also be configured with a bent portion. In this case, the upper bent portion of the plate portion 310 may be fixed in contact with the upper inner surface, i.e., the ceiling surface, of the container housing 100.

[0064] According to this embodiment of the present invention, the sealing force between the plate part 310 and the container housing 100 is further improved by the upper end bent part and / or the lower end bent part formed on the plate part 310. Therefore, it is possible to more reliably prevent flames and gases from leaking from the gap between the plate part 310 and the container housing 100. Also, according to this embodiment, the contact area between the plate part 310 and the container housing 100 is increased, and the supporting force of the container housing 100 by the plate part 310 is further increased.

[0065] Furthermore, as in the above-described embodiment, when one isolation partition 300 is provided with two plate portions 310, the bending direction of the end of each plate portion 310 may be outward. For example, when the isolation partition 300 is provided with two plates (a left plate and a right plate), the upper and lower ends of the left plate may be bent to the left, and the upper and lower ends of the right plate may be bent to the right. In this case, a longer gap may be formed between the ends of the two plates and the container housing 100. Therefore, the sealing performance due to the bending shape is further improved.

[0066] According to the present embodiment, a space capable of accommodating various components may be provided between the two plate portions 310 in one isolation bulkhead 300. For example, the isolation bulkhead 300 may accommodate a fire extinguishing agent for suppressing a fire in the space V1 between the two plate portions 310. As the fire extinguishing agent, various fire suppression materials known at the time of filing of the present invention may be used. In this case, when a fire occurs in a specific module stack, the fire extinguishing agent is used to suppress the fire in the specific module stack or to prevent the fire from spreading to other adjacent module stacks.

[0067] In addition, the isolation bulkhead 300 may be configured such that, in the event of a fire occurring in a particular module stack, the extinguishing agent remains only in the space V1 between the two plate portions 310, or flows from the space and leaks toward the module stack. In this case, a hole through which the extinguishing agent can leak may be formed in a part of the isolation bulkhead 300, for example, in the plate portion 310.

[0068] FIG. 7 is a cross-sectional view illustrating a schematic partial configuration of a battery container according to still another embodiment of the present invention.

[0069] 7, the battery container according to the present invention may further include a fire extinguishing liquid supply module. In particular, the fire extinguishing liquid supply module may include a fire extinguishing nozzle inside the isolation bulkhead 300, as indicated by E. Furthermore, the fire extinguishing nozzle E may be configured to inject fire extinguishing liquid, such as water, into the space V1 between the two plate portions 310. Here, the fire extinguishing nozzle E may be located at an upper portion in the space V1 between the two plate portions 310 and inject the fire extinguishing liquid downward.

[0070] The extinguishing nozzle E may supply extinguishing liquid when a fire occurs in an adjacent module stack. For example, the extinguishing nozzle E may be configured in the form of a glass bulb, and may be heated by a flame, etc., and broken to spray water. Alternatively, the extinguishing liquid supply module may include a fire sensor, a smoke sensor, etc., and detect a fire through these sensors to spray extinguishing liquid through the extinguishing nozzle E.

[0071] According to this embodiment of the present invention, when a thermal runaway or fire occurs in a specific module stack, it is possible to prevent or reduce heat or flame from passing through the isolation partition 300 and heading toward other module stacks. Therefore, it is possible to prevent or delay the spread of the fire throughout the battery container. Furthermore, in this embodiment, the fire extinguishing liquid such as water may be sprayed only inside the isolation partition 300 and not on the battery modules 200. In this case, it is possible to prevent problems such as electric shock accidents and electric leakage accidents from occurring, in which even normal battery modules 200 come into contact with the fire extinguishing liquid such as water and become unusable.

[0072] In addition, the blocking partition wall 300 may include a first pillar portion 320 supporting the plate portion 310 as shown in FIGS.

[0073] The first pillar 320 may be configured in a rod shape extending vertically, and an upper end and a lower end may be coupled to the container housing 100. For example, the upper end and the lower end of the first pillar 320 may be welded or bolted to the container housing 100. Alternatively, the first pillar 320 may be manufactured integrally with the container housing 100 from the beginning.

[0074] The first pillars 320 may contact or be coupled to the plate part 310 so that the plate part 310 can maintain its shape and position. For example, the first pillars 320 may be welded or bolted to the plate part 310. Furthermore, two or more first pillars 320 may be included in one isolation bulkhead 300. For example, as shown in FIG. 4 and FIG. 5, two first pillars 320 may be provided. The two first pillars 320 may be arranged at a predetermined distance apart in a direction perpendicular to the arrangement direction of the module stack in the horizontal direction, i.e., in the front-rear direction (Y-axis direction). In this case, the plate part 310 may be fixed by being coupled at its front end and rear end to the two first pillars 320 arranged in the front-rear direction. Furthermore, the plate part 310 may be configured in a form inserted between the two first pillars 320 as shown in FIG. 5.

[0075] According to this embodiment of the present invention, the isolation bulkhead 300 can be more easily installed inside the container housing 100, and the shape and position of the plate portion 310 can be more stably maintained. In addition, according to this embodiment, it is highly likely that both the fire blocking effect and the complementary effect of structural rigidity by the isolation bulkhead 300 are improved. For example, in this embodiment, the isolation bulkhead 300 may be configured in such a manner that the plate portion 310 includes a material having excellent fire blocking performance, such as a ceramic material, and the first pillar portion 320 includes a material having high mechanical strength. Furthermore, the plate portion 310 may include a mica material.

[0076] The first pillar 320 may have an internal space, as shown by V2 in Fig. 5. Furthermore, since the first pillar 320 is elongated in the vertical direction, the hollow V2 formed therein may also be elongated in the vertical direction. According to this embodiment of the present invention, the weight of the battery container can be further reduced, and manufacturing costs can be saved.

[0077] 3 to 6, the blocking partition 300 may include a first mounting portion 330. The configuration of the first mounting portion 330 will be described in more detail with reference to FIG.

[0078] FIG. 8 is a perspective view showing a schematic configuration of a first placement unit 330 according to an embodiment of the present invention.

[0079] 8 together with FIGS. 3 to 6, the first mounting part 330 may be configured to support each battery module 200 in the module stack. The first mounting part 330 may also be referred to as a first mounting frame or a first mounting bracket since it is configured in a frame or bracket form.

[0080] For example, the first placement part 330 may be configured as a plate extending long in one direction, for example, the front-rear direction (Y-axis direction). Furthermore, the first placement part 330 may be configured in a shape in which the center part is bent, particularly, in a shape in which it is bent by about 90 degrees, as shown in FIG. 8.

[0081] In this case, the first placement portion 330 may have a vertical portion 331 and a horizontal portion 332 around the bent portion. Here, the vertical portion 331 and the horizontal portion 332 may each be formed in a plate shape and may be integrated with each other.

[0082] Furthermore, the vertical part 331 may be configured as an upright plate and may be coupled to the first pillar part 320 or the plate part 310. To this end, a fastening hole as indicated by H1 may be formed in the vertical part 331. Furthermore, the horizontal part 332 may be configured as a lying plate and may support the battery module 200 on its upper surface.

[0083] The first mounting portion 330 may support a lateral lower edge of the battery module 200. For example, the first mounting portion 330 may support a left lower edge of the battery module 200. In this case, a right lower edge of the battery module 200 may be supported by another first mounting portion 330, for example, a first mounting portion 330 included in another isolation partition 300. That is, based on one battery module 200, two first mounting portions 330 may support both sides of the battery module 200, particularly, the left lower end and the right lower end, respectively.

[0084] A module stack facing one isolation barrier 300 may include a plurality of battery modules 200 stacked in the vertical direction. Accordingly, the isolation barrier 300 may include a plurality of first mounting portions 330 to support each of the plurality of stacked battery modules 200. Furthermore, a plurality of such first mounting portions 330 may be provided in a form spaced apart from each other by a predetermined distance in the vertical direction along the stacking direction of the battery modules 200.

[0085] Also, module stacks may be located on both sides of one isolation barrier 300. For example, different module stacks may be located on the left and right sides of one isolation barrier 300. Thus, one isolation barrier 300 may be provided with a plurality of first mounting portions 330 on both the left and right sides to support a plurality of battery modules 200 located on both the left and right sides, as shown in Figs. 4 and 6, etc.

[0086] According to this embodiment of the present invention, the battery modules 200 are supported by the isolation barrier 300. Therefore, there is no need to provide a separate rack frame in the battery container for maintaining the stacked state of the battery modules 200. Therefore, the manufacturing cost of the battery container can be reduced and the assembling and productivity can be improved. In addition, the weight of the battery container is reduced, making it easier to transport and install the battery container. In addition, the space occupied by the rack frame is reduced and the battery modules can be stacked up to the ceiling of the battery container, which is advantageous in reducing the size of the battery container and increasing the energy density.

[0087] 1 and 2, the battery container according to the present invention may include two or more isolating partitions 300. For example, the battery container may include seven isolating partitions 300, and each isolating partition 300 may be spaced apart from each other by a predetermined distance in the left-right direction.

[0088] In this case, the battery container may further include a support wall 400. The support wall 400 may be provided between two isolation partitions 300. The configuration of the support wall 400 will be described in more detail with reference to FIGS. 9 and 10.

[0089] Fig. 9 is a perspective view showing another partial configuration of the battery module 200 according to an embodiment of the present invention. For example, Fig. 9 is an enlarged view of part B2 in Fig. 2. Fig. 10 is an exploded perspective view of the configuration in Fig. 9.

[0090] 9 and 10 together with FIGS. 1 and 2, the battery container may include a support wall 400 in addition to the isolation partition wall 300. The upper and lower ends of the support wall 400 may be coupled to the upper and lower inner faces of the container housing 100, respectively, similar to the isolation partition wall 300. Thus, the support wall 400, together with the isolation partition wall 300, may support the upper plate of the container housing 100 upwardly, thereby complementing the structural rigidity of the container housing 100. In particular, the support wall 400 may be interposed between two isolation partition walls 300. Furthermore, a plurality of support walls 400 may be included in the battery container as shown in FIGS. 1 and 2. In this case, the plurality of support walls 400 and the plurality of isolation partition walls 300 may be alternately arranged in the horizontal direction.

[0091] Also, the support wall 400 may be configured to accommodate and support the battery module 200 together with the isolation partition 300. In particular, the support wall 400 may include a second pillar portion 420 and a second mounting portion 430. The second pillar portion 420 and the second mounting portion 430 of the support wall 400 may be configured the same as or similar to the first pillar portion 320 and the first mounting portion 330 of the isolation partition 300 described above. In particular, the second mounting portion 430 may be coupled to the second pillar portion 420 by a method such as bolt fastening, and may be provided in a plurality of second mounting portions in the vertical direction. Therefore, the plurality of battery modules 200 stacked in the vertical direction may be stably supported upward.

[0092] In particular, the support wall 400 may support different parts of the battery module 200 together with the other isolation partitions 300. For example, referring to the embodiment of FIG. 1, the support wall 400(W2) may support upwardly the left lower end of each battery module 200 belonging to the fourth stack S4 located on the right side by the second mounting portion 430 located on the right side. At this time, the right lower end of each battery module 200 belonging to the fourth stack S4 may be supported upwardly by the first mounting portion 330 provided on the left side of the isolation partition 300(F3) located a predetermined distance away from the right side of the support wall 400(W2). In addition, the support wall 400(W2) may support upwardly the right lower end of each battery module 200 belonging to the third stack S3 located on the left side by the second mounting portion 430 located on the left side. In this case, a lower left end of each battery module 200 belonging to the third stack S3 may be supported upward by a first mounting portion 330 provided on the right side of the blocking partition 300 (F2) located a predetermined distance away from the left side of the support wall 400 (W2). In this embodiment, it can be said that one lower end of each battery module 200 is supported by the first mounting portion 330 of the blocking partition 300, and the other lower end is supported by the second mounting portion 430 of the support wall 400.

[0093] Meanwhile, unlike the blocking partition 300, the support wall 400 may not have a structure corresponding to the plate portion 310. That is, the blocking partition 300 blocks the spaces on both sides by the plate portion 310, while the support wall 400 does not block the spaces on both sides because it does not have a structure corresponding to the plate portion 310. That is, the support wall 400 may be configured to be at least partially open in the horizontal direction. In particular, the support wall 400 may be configured to allow air to circulate between the spaces on both sides. For example, in the embodiment of FIG. 1, when the third stack S3 and the fourth stack S4 are located on the left and right sides of the support wall 400 (W2), air may circulate between the space where the third stack S3 is located and the space where the fourth stack S4 is located.

[0094] According to such an embodiment of the present invention, two or more horizontally arranged module stacks are included as components of one battery system, and each battery system can use one air conditioning module. For example, when 14 module stacks S1 to S14 are arranged horizontally in the left-right direction as in the embodiment shown in FIG. 1, two adjacent module stacks can form one battery system. For example, the first stack S1 and the second stack S2 can form one battery system, for example, the first system. Also, the third stack S3 and the fourth stack S4 can form another battery system, for example, the second system. And the fifth stack S5 and the sixth stack S6 can form the third system.

[0095] In this embodiment, a support wall 400 may be interposed between the module stacks included in one battery system to support the battery modules 200 located on both sides. Also, an isolation barrier 300 may be interposed between the module stacks included in different battery systems to support the battery modules 200 located on both sides.

[0096] For example, in the embodiment of Fig. 1, the third stack S3 and the fourth stack S4 are module stacks included together in the second system, which is one battery system, so a support wall 400 (W2) may be interposed between them. Therefore, cooling air can circulate between the third stack S3 and the fourth stack S4. Therefore, cooling air supplied from one air conditioning module, for example, an air conditioning device (HVAC: Heating, Ventilation, Air Conditioning) located at the front door of the third stack S3, may circulate through the opening of the support wall 400 (W2) to the space where the fourth stack S4 is located.

[0097] Meanwhile, since the second stack S2 is included in the first system, which is a battery system different from the third stack S3, a blocking partition 300F2 may be interposed between the second stack S2 and the third stack S3, instead of the support wall 400. In this case, the first system may have a separate air conditioning module independent of the second system.

[0098] According to this embodiment, even if different module stacks are used in the same battery system, integrated cooling control through one air conditioning module is possible. Also, according to this embodiment, air conditioning can be easily performed in the same battery system, and the spread of flame can be prevented between different battery systems. For example, even if a fire occurs in the third stack S3, the blocking partition 300 (F2) can prevent the flame from moving toward the second stack S2. Also, according to this embodiment, since the support wall 400 does not include a structure corresponding to the plate portion 310, the support wall 400 is lighter in weight than the blocking partition 300. Therefore, in this case, the weight of the battery container can be further reduced.

[0099] FIG. 11 is a cross-sectional view illustrating a partial configuration of a battery module 200 according to an embodiment of the present invention, viewed from above.

[0100] 11, the front end and rear end of the isolation bulkhead 300 may be configured to contact the front inner surface and rear inner surface of the container housing 100, respectively. For example, the container housing 100 may include a front plate 105 and a rear plate 106 as shown in FIG. 11 to close the front and rear of the internal space. Furthermore, the front plate 105 and / or the rear plate 106 may be provided with a door for opening and closing the internal space. Also, an air conditioning module may be attached to the front plate 105 and / or the rear plate 106 for air conditioning the container housing 100. As an example, an HVAC may be attached to a door provided on the front plate 105 of the container housing 100.

[0101] In this embodiment, the front end of the isolation partition 300 may contact the inner surface of the front plate 105 of the container housing 100 as shown by I1 in FIG. 11. In particular, the contact portion between the front end of the isolation partition 300 and the container housing 100 may be formed continuously from the upper end to the lower end. In addition, the rear end of the isolation partition 300 may contact the inner surface of the rear plate 106 of the container housing 100 as shown by I1' in FIG. 11. In addition, the contact portion between the rear end of the isolation partition 300 and the container housing 100 may also be formed continuously from the upper end to the lower end. As a more specific example, the first pillar portion 320 may be located at the front end and the rear end of the isolation partition 300. In this case, the front surface of the first pillar portion 320 located at the front end may contact the inner surface of the front plate 105.

[0102] According to this embodiment of the present invention, the blocking performance of the isolation bulkhead 300 against fire and the like is further improved. That is, according to this embodiment, it is possible to prevent flames and high-temperature vent gas from transferring from the front side or the rear side of the isolation bulkhead 300. Therefore, the effect of preventing the spread of fire between adjacent module stacks arranged with the isolation bulkhead 300 interposed therebetween is further improved.

[0103] 12 is a cross-sectional view showing a partial configuration of a battery module 200 according to another embodiment of the present invention, viewed from above, and FIG. 13 is an enlarged view of a portion J1 in FIG.

[0104] First, referring to FIG. 12, the front end and rear end of the isolation partition 300 may have inclined surfaces as indicated by J1, J2, J3, and J4. In particular, the inclined surfaces may be configured to be inclined inward as they go in the front-rear direction. Here, the inward direction may refer to the direction in which the module stack is housed. For example, referring to the configuration of FIG. 13, the left side of the front end of the isolation partition 300, particularly the left side surface of the front first pillar 320, may have an inclined surface inclined leftward as it goes forward (in the -Y axis direction) as indicated by K. Also, in FIG. 12, the right side surface of the front first pillar 320 may have an inclined surface inclined rightward as it goes forward as indicated by J2. Also, in FIG. 12, the left side surface of the rear first pillar 320 may have an inclined surface inclined leftward as it goes backward as indicated by J3. 12, a slope inclined toward the right as it goes toward the rear, as shown by J4, may be formed on the right side of the rear first pillar 320. In particular, in the present embodiment, the isolation partition 300, particularly the first pillar 320, may have a portion that gradually becomes wider toward the outside (front or rear).

[0105] According to this embodiment of the present invention, it is possible to more reliably prevent flames, gases, etc. from moving along the front end or rear end of the isolation bulkhead 300 toward other stacks. In particular, according to this embodiment, as shown by the arrows in FIG. 13, flames and gases can bend inward along the inclined surface K. Therefore, it is possible to more reliably prevent flames and gases from moving along the end of the isolation bulkhead 300 beyond the isolation bulkhead 300 to other module stacks. In addition, according to this embodiment, it is possible to further increase the contact area between the isolation bulkhead 300 and the inner surface of the container housing 100. Therefore, it is possible to more reliably prevent flames and gases from flowing in through the gap between the isolation bulkhead 300 and the inner surface of the container housing 100.

[0106] FIG. 14 is a perspective view showing a schematic configuration of a part of an isolation barrier 300 according to still another embodiment of the present invention.

[0107] 14, the plate part 310 included in the isolation barrier 300 may have projections and recesses. Here, the projections and recesses may be formed in the form of protrusions or grooves formed on the plate part 310. More specifically, as shown by P1 in FIG. 14, the plate part 310 may have a projection extending in the vertical direction (Z-axis direction). The projection P1 may be configured to protrude in the horizontal direction, for example, to the left or right side, where the battery module 200 is located. The projections P1 may be arranged in a plurality in the front-rear direction (Y-axis direction) in the space between two first mounting parts 330 arranged adjacent to each other in the vertical direction.

[0108] According to this embodiment of the present invention, when a flame is discharged from a particular battery module 200, the protrusions P1 provided on the plate portion 310 can effectively prevent the flame from moving in the front-rear direction (Y-axis direction) along the surface of the plate portion 310. In particular, since a flame has a high tendency to move in a straight line, the protrusions P1 formed long in the vertical direction and arranged in multiple positions in the front-rear direction suppress the flame from moving in the front-rear direction. Therefore, in this case, the flame can be prevented from being discharged to the front or rear of the battery container.

[0109] FIG. 15 is a perspective view showing a schematic configuration of a portion of an isolation barrier 300 according to still another embodiment of the present invention.

[0110] 15, a protrusion, designated by P2, extending long in the front-rear direction (Y-axis direction) may be provided on the surface of the plate portion 310 included in the blocking partition 300. A plurality of such protrusions P2 may be arranged in the vertical direction in the space between two first mounting portions 330 arranged adjacent to each other in the vertical direction.

[0111] According to this embodiment of the present invention, when a flame is emitted from a particular battery module 200, the protrusion P2 provided on the plate portion 310 can prevent the flame from moving in the vertical direction (Z-axis direction) along the surface of the plate portion 310. Therefore, the flame is prevented from moving to other battery modules 200 stacked above or below within the same module stack. Therefore, the spread of the fire between the battery modules 200 can be reduced or delayed.

[0112] 16 is an exploded perspective view illustrating a battery container according to another embodiment of the present invention before the lower portion of the isolation bulkhead 300 is coupled to the lower plate 102 of the container housing 100.

[0113] 16, an insertion groove may be formed in the inner surface of the container housing 100, for example, the upper surface (bottom surface) of the lower plate 102, as indicated by G1. At least a portion of the isolation partition 300, for example, its lower end portion, may be configured to be inserted into the insertion groove G1. Therefore, the insertion groove G1 of the container housing 100 may have a shape corresponding to the lower end portion of the isolation partition 300. In particular, the insertion groove G1 of the container housing 100 may be formed long in the front-rear direction. In this case, the isolation partition 300 may be inserted and fastened along the insertion groove G1 of the container housing 100.

[0114] Meanwhile, although only the lower part of the container housing 100 is shown in FIG. 16, the upper part of the container housing 100 may also be provided with such an insertion structure for the isolation bulkhead 300 .

[0115] According to this embodiment of the present invention, it is possible to more reliably prevent flames and gases from leaking between the isolation partition 300 and the container housing 100. For example, since the lower end of the isolation partition 300 is inserted into the insertion groove G1 formed in the lower plate 102 of the container housing 100, the flame outflow path between the lower end of the isolation partition 300 and the lower plate 102 is formed in a bent shape and is longer. Therefore, it is not easy for flames to move through the gap between the lower end of the isolation partition 300 and the lower plate 102.

[0116] Also, according to this embodiment, the position of the blocking partition 300 is stably fixed inside the container housing 100. This further improves the effect of the blocking partition 300 in supplementing the rigidity of the container housing 100. Furthermore, according to this embodiment, the installation position of the blocking partition 300 is guided by the insertion groove G1, making it easier to install the blocking partition 300 inside the container housing 100.

[0117] 17 is a schematic diagram showing a partial configuration of a battery container according to still another embodiment of the present invention. FIG. 17 also shows a state before the lower part of the isolation bulkhead 300 is coupled to the lower plate 102 of the container housing 100.

[0118] 17, similarly to the embodiment of Fig. 16, an insertion groove as indicated by G2 may be formed on the inner surface of the container housing 100 so that a portion of the isolation bulkhead 300 may be inserted therein. However, unlike the embodiment of Fig. 16, the embodiment of Fig. 17 may have a first protrusion and a second protrusion as indicated by L1 and L2 provided inside the insertion groove G2.

[0119] In particular, the protrusions L1 and L2 provided inside the insertion groove G2 may be configured to correspond to the shape of the end of the isolation partition 300. For example, as shown by V1 in FIG. 5, a space may be formed between the two plates constituting the plate portion 310 in the isolation partition 300. At this time, the first protrusion L1 may be inserted into the space V1 between the two plate portions 310. The two plates may be fitted into the insertion grooves G2 formed on the left and right sides of the first protrusion L1. Also, as shown by V2 in FIG. 5, a space may be formed in the center of the first pillar portion 320 in the isolation partition 300. At this time, the second protrusion L2 may be inserted into the hollow V2 of the first pillar portion 320. The two first pillar portions 320 may be fitted into the insertion grooves G2 formed around the second protrusion L2.

[0120] In this embodiment, the fastening force between the isolation partition 300 and the container housing 100 is further improved. Also, according to this embodiment, the isolation partition 300 and the container housing 100 are more closely attached to each other, and the gap formed between the isolation partition 300 and the container housing 100 may be configured in a shape that is bent several times. Therefore, it is possible to more effectively prevent fire, gas, etc. from leaking through the gap between the isolation partition 300 and the container housing 100.

[0121] FIG. 18 is a diagram showing a schematic configuration of a portion of a support member according to still another embodiment of the present invention.

[0122] Referring to FIG. 18, the plate portion 310 may have an insertion groove as indicated by G3 such that at least a portion of the first mounting portion 330 is inserted therein. The insertion groove G3 may be referred to as a third insertion groove to distinguish it from the above-mentioned insertion grooves G1 and G2. For example, as shown in FIG. 18, the third insertion groove G3 may be formed in a shape recessed inward in a horizontal direction such that a central portion of the first mounting portion 330 excluding both ends is inserted therein. In particular, when the plate portion 310 is formed on the left and right sides of the blocking partition wall 300, the third insertion groove G3 of the right plate portion 310 may be formed in a shape recessed from the right side surface toward the left side, and the third insertion groove G3 of the left plate portion 310 may be formed in a shape recessed from the left side surface toward the right side. Here, the third insertion groove G3 may be formed by partially thinning the thickness of the plate portion 310 or by bending a portion of the plate portion 310.

[0123] Also, the first pillar 320 may be formed with an insertion groove as indicated by G4 so that a portion of the first mounting portion 330 is inserted therein. Such an insertion groove G4 may be referred to as a fourth insertion groove in order to distinguish it from the above-mentioned insertion grooves G1 to G3. The fourth insertion groove G4 may form a groove into which the first mounting portion 330 is inserted together with the third insertion groove G3. Furthermore, the third insertion groove G3 is formed in a form that extends long in the front-rear direction (Y-axis direction) in accordance with the shape of the first mounting portion 330, and the fourth insertion groove G4 may be located at an end along the extension direction of the third insertion groove G3.

[0124] 18, two first pillars 320 may be arranged in the front-rear direction on one blocking partition 300. The two first pillars 320 may be located on the front and rear sides of the plate part 310. Thus, the first pillar 320 located on the front side of the plate part 310 may have a fourth insertion groove G4 formed therein to extend from the front end of the third insertion groove G3. The first pillar 320 located on the rear side of the plate part 310 may have a fourth insertion groove G4 formed therein to extend from the rear end of the third insertion groove G3.

[0125] In particular, the first mounting part 330 may be coupled to the left side and the right side of each first pillar 320. Thus, the fourth insertion groove G4 formed on the right side of the front first pillar 320 may be formed in a concave shape with the right side and the rear side open so that the front end of the first mounting part 330 is inserted from the right side. The fourth insertion groove G4 formed on the right side of the rear first pillar 320 may be formed in a concave shape with the right side and the front side open so that the rear end of the first mounting part 330 is inserted. The fourth insertion groove G4 formed on the left side of the front first pillar 320 may be formed in a concave shape with the left side and the rear side open so that the front end of the first mounting part 330 is inserted from the left side. The fourth insertion groove G4 formed on the left side of the rear first pillar 320 may be formed in a concave shape with the left side and the front side open so that the rear end of the first mounting part 330 is inserted.

[0126] According to this embodiment of the present invention, the fixing force of the first mounting portion 330 is significantly improved. In particular, according to this embodiment, the first mounting portion 330 is stably supported upward by the third insertion groove G3 and the fourth insertion groove G4. Furthermore, according to this embodiment, the first mounting portion 330 is prevented from moving in the front-rear direction. Furthermore, according to this embodiment, the assembly position of the first mounting portion 330 is guided by the third insertion groove G3 and the fourth insertion groove G4. Therefore, in this case, the assemblability of the battery container can be further improved.

[0127] Meanwhile, in the embodiment of FIG. 18, an insertion groove into which the first mounting portion 330 is inserted is formed in the blocking partition 300, but an insertion groove into which the second mounting portion 430 is inserted may also be formed in the support wall 400 in a similar form.

[0128] In addition to the above-mentioned components, the battery container may further include various other components known at the time of filing of the present invention. For example, the battery container may further include an electrical component such as an AC / DC panel. Also, the battery container may include one or more control modules 500 as shown in FIG. 1. The control module 500 may be configured to control the charging and discharging operation of the battery module 200 included in the battery container, or to transmit and receive data with other components outside the battery container. In particular, when a plurality of battery systems are included in the battery container, a plurality of control modules 500 may be included. In this case, a separate control module 500 may be included in each battery system to independently control the corresponding battery system.

[0129] The energy storage system according to the present invention includes the battery container according to the present invention. The energy storage system according to the present invention may further include two or more battery containers. The energy storage system according to the present invention may further include a control container for controlling various operations, such as charging and discharging operations, of the one or more battery containers in addition to the battery container.

[0130] Meanwhile, terms indicating directions such as up, down, left, right, front, and back are used in this specification, but such terms are used for convenience of explanation, and it will be obvious to those skilled in the art that such terms may change depending on the position of a target object, the position of an observer, etc. Furthermore, although the terms inside and outside are used in this specification, the inside of each component means a direction toward its center, and the outside means an opposite direction, unless otherwise specified.

[0131] Although the present invention has been described above using limited embodiments and drawings, the present invention is not limited thereto, and it goes without saying that various modifications and variations can be made by a person having ordinary knowledge in the technical field to which the present invention belongs within the scope of the technical concept of the present invention and the scope of the claims.
