Description

Technical Field

[0001] Aspects of embodiments of the present disclosure relate to an energy storage system. Background Art

[0002] Generally, an energy storage system (ESS) is a device that can store surplus electricity or store electricity generated using renewable energy. The ESS can be configured by installing a plurality of battery modules in a rack and accommodating a plurality of racks in a container. The battery module can be constructed by assembling a plurality of secondary batteries electrically connected to each other into various structures.

[0003] In such an ESS, when a fire breaks out due to thermal runaway occurring during the charging and discharging process of the secondary battery or other electrical defects in the secondary battery, there is a risk that all components inside the container can be exposed to the fire and be completely burned or otherwise damaged by the fire. To prevent the above risks, a fire compartment can be constructed by setting an impermeable firewall in the middle of the container. However, in this case, each compartment requires a separate air conditioner equipment, which increases the cost and is disadvantageous in terms of battery energy density.

[0004] The above information disclosed in the technology forming the background of the present disclosure is only intended to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute related art. Summary of the Invention

[0055] Herein, some embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. The terms or words used in this specification and claims should not be construed as limited to the ordinary or dictionary meanings, and should be interpreted as meanings and concepts consistent with the technical idea of the present disclosure based on the principle that the inventor can be his / her own lexicographer to appropriately define the concept of the terms.

[0056] The embodiments described in this specification and the configurations shown in the drawings are provided as some example embodiments of the present disclosure, and do not represent all the technical ideas, aspects and features of the present disclosure. Therefore, it should be understood that there may be various equivalents and modifications that can replace or modify the embodiments described herein at the time of filing this application.

[0057] It should be understood that when an element or layer is referred to as being "on", "connected to" or "coupled to" another element or layer, it can be directly on, connected to or coupled to another element or layer, or there may also be one or more intermediate elements or layers. When an element or layer is referred to as being "directly on", "directly connected to" or "directly coupled to" another element or layer, there are no intermediate elements or layers. For example, when a first element is described as being "coupled" or "connected" to a second element, the first element can be directly coupled or connected to the second element, or the first element can be indirectly coupled or connected to the second element via one or more intermediate elements.

[0058] In the accompanying drawings, for clarity of illustration, the dimensions of various elements, layers, etc. may be enlarged. Identical reference numerals designate identical or similar elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Further, when used in the description of embodiments of the present disclosure, the term "may" refers to "one or more embodiments of the present disclosure". Phrases such as "at least one of..." and "any one of...", when before / after a list of elements, modify the entire list of elements and do not modify a single element in the list. When phrases such as "at least one of A, B, and C", "at least one selected from the group consisting of A, B, and C", or "at least one selected from A, B, and C" are used to specify a list of elements A, B, and C, the phrase may refer to any and all suitable combinations or subsets of A, B, and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the terms "use" and "be used" may be considered synonymous with the terms "utilize" and "be utilized", respectively. As used herein, the terms "substantially", "about", and similar terms are used as approximate terms rather than terms of degree, and are intended to account for the inherent deviations in measured or calculated values that would be recognized by a person of ordinary skill in the art.

[0059] It should be understood that although terms such as "first", "second", and "third", etc. may be used herein to describe various elements, components, regions, layers, and / or sections of regions, these elements, components, regions, layers, and / or sections of regions should not be limited by these terms. These terms are used to separate one element, component, region, layer, or section of a region from another element, component, region, layer, or section of a region. Thus, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or section of a region discussed below may be referred to as the second element, component, region, layer, or section of a region.

[0060] For ease of description, spatial relative terms, such as "beneath", "below", "under", "above", and "on", etc. may be used herein to describe the relationship of one element or feature to another element or feature, as illustrated in the accompanying drawings. It should be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, an element or feature described as "beneath" or "below" another element or feature will be oriented "above" or "over" the other element or feature. Thus, the term "below" can encompass both an orientation of above and below. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should thus be interpreted accordingly.

[0061] The terms used in this disclosure are for the purpose of describing embodiments of the disclosure and are not intended to limit the disclosure. As used herein, unless the context clearly indicates otherwise, the singular form "a" is intended to also include the plural form. It should be further understood that the terms "comprising" and / or "having", when used in this specification, specify the presence of the recited features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0062] Also, any numerical range disclosed and / or set forth herein is intended to include all sub-ranges of the same numerical precision included within the set forth range. For example, the range "1.0 to 10.0" is intended to include between the minimum value of 1.0 and the maximum value of 10.0 set forth (and including 1.0 and 10.0), i.e., all sub-ranges having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit set forth herein is intended to include all lower numerical limits falling therein, and any minimum numerical limit set forth in this specification is intended to include all higher numerical limits falling therein. Accordingly, the applicant reserves the right to amend this specification (including the claims) to expressly set forth any sub-ranges included within the ranges expressly set forth herein.

[0063] Referring to two compared elements, features, etc. as "the same" may mean that they are "substantially the same". Thus, the phrase "substantially the same" may include cases considered to have a low deviation in the art, such as a deviation of less than 5%. Additionally, when a certain parameter is referred to as uniform in a given region, this may mean that it is uniform in terms of the average value.

[0064] Throughout the specification, unless otherwise stated, each element may be singular or plural.

[0065] When any element is referred to as being "above (or below)" or "on (or under)" (or being located "above (or below)" or "on (or under)") a component, this may mean that the any element is placed in contact with the upper (or lower) surface of the component, or it may mean that another component may be between the component and any element disposed (or located) above (or below) (or on (or under)) the component.

[0066] In addition, it should be understood that when an element is referred to as being "coupled", "linked", or "connected" to another element, these elements can be directly "coupled", "linked", or "connected" to each other, or there can be one or more intermediate elements therebetween, through which the element can be "coupled", "linked", or "connected" to the other element. In addition, when a part is referred to as being "electrically coupled" to another part, the part can be directly electrically connected to the other part, or there can be one or more intermediate parts therebetween, such that the part and the other part are indirectly electrically connected to each other.

[0067] Throughout the specification, unless otherwise stated, when referring to "A and / or B", it means A, B, or A and B. That is, "and / or" includes any or all combinations of the recited items. Unless otherwise indicated, when referring to "C to D", it means greater than or equal to C and less than or equal to D.

[0068] The terms used in this specification are for describing embodiments of the present disclosure and are not intended to limit the present disclosure.

[0070] Reference Figure 1 and Figure 2 According to this embodiment, the energy storage system includes a container 100, a receiving portion 200, a partition member 300, at least one ventilation hole 400, and at least one blocking member 500.

[0071] The container 100 can form the appearance of the energy storage system. Examples of the container 100 can include various types of closed structures with an empty interior, such as independent buildings, rooms within a building, and containers, etc. In addition to Figure 1 the rectangular parallelepiped shape illustrated in

[0072] The container 100 can be any suitable shape, such as a polyhedral shape and a circular shape, etc., other than Figure 1 and Figure 2 illustrates an embodiment in which three receiving portions 200 are formed inside the container 100, but the number of the receiving portions 200 is not limited thereto, and the receiving portions 200 can be any other suitable number, such as two or four, etc.

[0073] Each of the receiving portions 200 can be located at different positions inside the container 100. In Figure 1 and Figure 2In the illustrated embodiments, a plurality of receiving portions 200 may be arranged in a row inside the container 100. In one or more embodiments, the plurality of receiving portions 200 may be arranged in a lattice shape or vertically stacked inside the container 100. The shape and / or volume of each receiving portion 200 may be the same as or different from each other.

[0074] Each receiving portion 200 may receive the battery rack 10 or the air conditioner 20 therein.

[0075] The battery rack 10 may include a rack frame 11 having a plurality of storage spaces and a plurality of battery modules 12 disposed in the storage spaces of the rack frame 11 and electrically connected to each other. The battery module 12 may include a plurality of battery cells capable of storing and / or discharging electric power.

[0076] The air conditioner 20 may be a hair dryer device or a heating, ventilation, and air conditioning (HVAC) device configured to control the flow rate, temperature, and humidity of the surrounding air.

[0077] The battery rack 10 and the air conditioner 20 may each be received in any pair of adjacent receiving portions 200. In Figure 1 and Figure 2 In the illustrated embodiments, among the three receiving portions 200 arranged in a row inside the container 100, the central receiving portion 200 may receive the air conditioner 20, and the receiving portions 200 on both sides (e.g., opposite sides of the central receiving portion 200) may each receive the battery rack 10. However, the arrangement of the battery rack 10 and the air conditioner 20 is not limited thereto, and the design of the arrangement of the battery rack 10 and the air conditioner 20 may be modified to any other suitable configuration in which at least one of the battery rack 10 and the air conditioner 20 is received in the plurality of receiving portions 200.

[0078] The partition 300 is between a pair of adjacent receiving portions 200 and separates (divides or separates) the pair of adjacent receiving portions 200 from each other. The partition 300 according to the present embodiment may have a substantially flat plate shape. The partition 300 may be parallel to (or substantially parallel to) the boundary between the pair of adjacent receiving portions 200. The partition 300 may be arranged such that two surfaces of the partition 300 face the pair of adjacent receiving portions 200. The area of the partition 300 may be larger than the area of the boundary between the pair of adjacent receiving portions 200. The partition 300 may be made of a non-combustible and fire-resistant material such as concrete, ceramic, or steel to prevent damage caused by flames or the like in the event of a fire. The partition 300 may include a plurality of partitions 300. Each partition 300 may be separately arranged between any pair of receiving portions 200.

[0079] One or more ventilation holes 400 pass through the partition member 300 and are connected to adjacent receiving portions 200 on both sides thereof. That is, each of the one or more ventilation holes 400 can be used as a path through which air can be transmitted from one of the pair of adjacent receiving portions 200 to the other receiving portion 200 through the ventilation hole. Each of the ventilation holes 400 can have any suitable configuration, wherein the area of the ventilation hole 400 is smaller than the area of the partition member 300. At least one ventilation hole 400 can be a plurality of ventilation holes 400. The plurality of ventilation holes 400 can be spaced apart from each other on the partition member 300. The plurality of ventilation holes 400 can be arranged in a row in the vertical direction or in more than two rows.

[0080] The blocking member 500 is configured to block the flame or smoke generated in the receiving portion 200 from passing through the ventilation hole 400. In one or more embodiments, the blocking member 500 can be configured to allow the air inside any one of the receiving portions 200 to be transmitted through the ventilation hole 400 to the adjacent receiving portion 200 under normal operating conditions, and block the flame or smoke generated in one receiving portion 200 from passing through the ventilation hole 400 to the adjacent receiving portion 200 in case of a fire. At least one blocking member 500 can be a plurality of blocking members 500. The plurality of blocking members 500 can be respectively located in the ventilation holes 400 in each partition member 300.

[0081] Figure 3 To schematically illustrate a perspective view of the configuration of the blocking member 500 according to the first embodiment of the present disclosure, and Figure 4 To Figure 3 illustrate a perspective view of the configuration of the blocking member 500 according to the first embodiment of the present disclosure from a different angle.

[0082] Refer to Figure 3 and Figure 4 According to this embodiment, the blocking member 500 can include at least one louver 510 (for example, a plurality of louvers 510).

[0083] The louver 510 extends from the partition member 300 and faces the ventilation hole 400. The louver 510 according to this embodiment can have the shape of a plate extending from the partition member 300 toward the receiving portion 200, and its inner surface faces the ventilation hole 400. The louver 510 can be made of the same material as the partition member 300. The louver 510 can be inclined with respect to the partition member 300. In Figure 3 and Figure 4In the illustrated embodiment, the louver 510 may extend upward from the lower side of the ventilation hole 400 and may be configured (e.g., oriented) such that the distance from the louver 510 to the ventilation hole 400 increases toward the end portion of the louver 510. Thus, air having a relatively low viscosity can smoothly pass through the ventilation hole 400, and smoke and flames having a relatively higher viscosity than air (which move in a straight line and do not flow like air) can be blocked by the outer surface of the louver 510 and not introduced into the ventilation hole 400.

[0084] The area of the louver 510 may be larger than the area of the ventilation hole 400. Thus, the louver 510 can prevent (or at least mitigate) the direct introduction of flames or smoke into the ventilation hole 400 without disturbing the outer surface of the louver 510.

[0085] In an embodiment where the ventilation hole 400 includes a plurality of ventilation holes 400, the louver 510 may include a plurality of louvers 510. The plurality of louvers 510 may extend from different positions of the partition 300, and each louver may face one of the plurality of ventilation holes 400 respectively.

[0086] The louver 510 may extend toward the accommodation portion 200 that accommodates the battery rack 10 in the adjacent accommodation portion 200. Figure 3 and Figure 4 Illustrate the following embodiment: The battery rack 10 and the air conditioner 20 are each accommodated in the pair of adjacent accommodation portions 200, and the louver 510 is on or only on one surface of the partition 300. However, when all the battery racks 10 are accommodated in the pair of adjacent accommodation portions 200, the louver 510 may be on two surfaces (opposite surfaces) of the partition 300.

[0087] Hereinafter, the operation of the energy storage system according to the first embodiment of the present disclosure will be described.

[0088] Figure 5 and Figure 6 A view schematically illustrating the operation process of the energy storage system according to the first embodiment of the present disclosure.

[0089] When no fire occurs, the air flowing inside any one of the accommodation portions 200 is transmitted through the ventilation hole 400 to the inside of the adjacent accommodation portion 200 and circulates in the plurality of accommodation portions 200. During this process, the air conditioner 20 can continuously supply a flow force to the air circulating in the plurality of accommodation portions 200, and thus can further improve the air circulation efficiency. Therefore, during normal operating conditions, the internal environmental conditions of the plurality of accommodation portions 200 can be kept the same.

[0090] When a fire breaks out in the battery rack 10 housed in any one of the accommodating portions 200, the flame C generated in the area adjacent to the partition member 300 increases in size due to continuous combustion, and when it grows to a predetermined size or larger, it contacts the outer surface of the shutter 510.

[0091] Since the shutter 510 faces the ventilation hole 400, the flame C contacting the outer surface of the shutter 510 may not be introduced into the ventilation hole 400, and thus the spread of fire through the ventilation hole 400 can be blocked (or at least mitigated).

[0092] In addition, the smoke B generated during the combustion of the flame C contacts the partition member 300 and rises along the partition member 300 due to the density difference from the air A.

[0093] The smoke B contacts the outer surface of the shutter 510 while rising along the partition member 300.

[0094] Since the smoke B has a relatively higher viscosity than the air A, the smoke B is not introduced into the ventilation hole 400 through the inner surface of the shutter 510, but remains in contact with the outer surface of the shutter 510 and continues to move upward. By repeating such an operation until the smoke B reaches the upper end portion of the partition member 300, the spread of fire through the ventilation hole 400 can be blocked.

[0095] Hereinafter, the configuration of the energy storage system according to the second embodiment of the present disclosure will be described.

[0096] Figure 7 A perspective view schematically illustrating the configuration of the energy storage system according to the second embodiment of the present disclosure, Figure 8 A front view schematically illustrating the configuration of the energy storage system according to the second embodiment of the present disclosure, Figure 9 A perspective view schematically illustrating the configuration of the blocking member according to the second embodiment of the present disclosure, and Figure 10 An enlarged view schematically illustrating the configuration of the blocking part according to the second embodiment of the present disclosure.

[0097] Refer to Figures 7 - 9 According to this embodiment, the energy storage system includes a container 100, an accommodating portion 200, at least one partition member 300, at least one ventilation hole 400, and at least one blocking member 500.

[0098] The energy storage system according to the second embodiment of the present disclosure can be configured to be different from the energy storage system according to the first embodiment of the present disclosure only in the detailed configuration of the blocking member 500.

[0099] Therefore, when describing the energy storage system according to the second embodiment of the present disclosure, only the detailed configuration of the blocking member 500 that has not been described in the description of the energy storage system according to the first embodiment of the present disclosure will be described.

[0100] The description of the energy storage system according to the first embodiment of the present disclosure can be directly applied to the remaining components of the energy storage system according to the second embodiment of the present disclosure.

[0101] Figure 9 An embodiment in which the ventilation holes 400 continuously extend along the edge of the partition member 300 is illustrated, but the shape of the ventilation holes 400 is not limited thereto, and the ventilation holes 400 can have any other suitable configuration, such as being located in the central portion (or substantially central portion) of the partition member 300, as a plurality of ventilation holes 400 in different positions of the partition member 300, and so on.

[0102] The blocking member 500 according to the present embodiment may include a blocking body 521 and a coating 523.

[0103] The blocking body 521 is fixed to the partition member 300 and faces the ventilation holes 400. The blocking body 521 may be inserted into the ventilation holes 400 and fixed to the inner surface of the partition member 300, and the outer peripheral surface of the partition member 300 surrounds the ventilation holes 400. The shape and area of the blocking body 521 may correspond to the shape and area of the ventilation holes 400.

[0104] Connected to the ventilation holes 400, for example, a plurality of meshes 522 communicating with the ventilation holes 400 may be in the blocking body 521. Both sides of the meshes 522 may be connected to adjacent accommodation portions 200 through the ventilation holes 400. The plurality of meshes 522 may be spaced apart from each other and form a lattice shape. Therefore, the blocking body 521 may have the shape of a mesh net, in which a plurality of linear members cross each other in a lattice shape. Except for Figure 10 the quadrilateral shape illustrated in, the cross-sectional shape of the meshes 522 may have any other suitable shape, such as a circular shape, etc.

[0105] The coating 523 is on the surface of the barrier 521 and is configured to open or close the mesh holes 522 in response to a temperature change. In response to the coating 523 being heated to a set temperature or higher, the coating 523 can be configured to expand in volume and close the mesh holes 522. Thus, the coating 523 can keep the mesh holes 522 in an open state under normal operating conditions and allow air to flow through the ventilation holes 400, and can close the mesh holes 522 in the event of a fire to restrict (or at least mitigate) the passage of flames or smoke through the ventilation holes 400. The coating 523 according to the present embodiment can include a foamable refractory coating configured to form an insulating layer that expands several to dozens of times when the dry coating film carbonizes in response to exposure to heat. The set temperature can be any suitable temperature within a temperature range capable of causing the coating 523 to expand in response to a fire occurring in one of the accommodation portions 200.

[0106] The coating 523 can surround the perimeter of the mesh holes 522. That is, the coating 523 can continuously extend along the boundary between the barrier 521 and the mesh holes 522.

[0107] In one or more embodiments, the width L of the mesh holes 522 can satisfy the following Expression 1.

[0108] Expression 1

[0109] L≤t×α×2

[0110] Where L represents the width of the mesh holes 522 and can be the distance between opposite sides in embodiments where the mesh holes 522 have a polygonal shape, or the diameter of the mesh holes 522 in embodiments where the mesh holes 522 have a circular shape; t represents the thickness of the coating 523 and can be the distance between the inner diameter and the outer diameter of the coating 523 applied to the barrier 521; α represents the minimum expansion rate of the coating 523 and can be a value obtained by dividing the minimum expansion volume of the coating 523 by the initial volume of the coating 523 when the coating 523 is heated to a set temperature or higher. The minimum expansion rate α of the coating 523 can have any suitable value depending on the type and proportion of the foamable refractory coating contained therein.

[0111] Referring to Expression 1, the width L of the mesh holes 522 can be less than or equal to the value obtained by multiplying the minimum expansion thickness of the coating 523 by 2. Thus, even when the coating 523 expands to the minimum volume in the event of a fire, the coating 523 can completely close the mesh holes 522.

[0112] Hereinafter, the operation of the energy storage system according to the second embodiment of the present disclosure will be described.

[0113] Figure 11 and Figure 12 is a view schematically illustrating the operation process of the energy storage system according to the second embodiment of the present disclosure.

[0114] Reference Figure 11 , in response to no fire occurring (i.e., under normal operating conditions), the volume of the coating 523 applied to the surface of the barrier 521 remains at its initial volume, and the mesh holes 522 remain in the open state.

[0115] Thus, the air flowing inside any one of the accommodation portions 200 can receive the flow force from the air conditioner 20 to pass through the ventilation holes 400 and through the mesh holes 522, and can be transmitted to the inside of the adjacent accommodation portion 200.

[0116] Reference Figure 12 , in response to a fire occurring in any one of the accommodation portions 200 due to a failure of the battery rack 10 or the air conditioner 20, the temperature of the coating 523 increases.

[0117] In response to the coating 523 being heated to a set temperature or higher, the volume of the coating 523 around the perimeter of each of the mesh holes 522 expands and closes the mesh holes 522.

[0118] When the mesh holes 522 are completely closed, the ventilation holes 400 are separated from the accommodation portions 200, and the spread of fire through the ventilation holes 400 is blocked (or at least mitigated).

[0119] Hereinafter, the configuration of the energy storage system according to the third embodiment of the present disclosure will be described.

[0120] Figure 13 A perspective view schematically illustrating the configuration of the energy storage system according to the third embodiment of the present disclosure, Figure 14 A front view schematically illustrating the configuration of the energy storage system according to the third embodiment of the present disclosure, Figure 15 A plan view schematically illustrating the configuration of the energy storage system according to the third embodiment of the present disclosure, Figure 16 A perspective view schematically illustrating the configuration of the barrier member according to the third embodiment of the present disclosure, and Figure 17 An example of the ventilation hole being Figure 16 A perspective view of the state where the ventilation hole is closed by the barrier member.

[0121] Reference Figures 13 - 17 , the energy storage system according to the present embodiment includes a container 100, accommodation portions 200, at least one partition member 300, at least one ventilation hole 400, and at least one barrier member 500.

[0122] The energy storage system according to the third embodiment of the present disclosure can be configured to be different from the energy storage system according to the first embodiment of the present disclosure only in the detailed configuration of the barrier member 500.

[0123] Therefore, when describing the energy storage system according to the third embodiment of the present disclosure, only the detailed configuration of the blocking member 500 that is not described in the energy storage system according to the first embodiment of the present disclosure will be described.

[0124] The description of the energy storage system according to the first embodiment of the present disclosure can be directly applied to the remaining components of the energy storage system according to the third embodiment of the present disclosure.

[0125] The blocking member 500 according to the present embodiment may include a damping member 531 and an adjusting member 533.

[0126] Hereinafter, as Figure 16 and Figure 17 illustrated in, an embodiment in which the ventilation hole 400 passes through all regions except for the two end portions of the partition member 300 will be described.

[0127] The damping member 531 may be rotatably connected to the partition member 300 and open or close the ventilation hole 400 according to the rotation direction of the damping member 531. In one or more embodiments, the damping member 531 may close the ventilation hole 400 by rotating in a first direction and open the ventilation hole 400 by rotating in a second direction opposite to the first direction. Here, the first direction may be a clockwise direction or a counterclockwise direction around the rotation axis of the damping member 531.

[0128] The damping member 531 according to the present embodiment may include a plurality of dampers 532.

[0129] The damper 532 may have a flat plate shape. The longitudinal direction of the damper 532 may be parallel to (or substantially parallel to) the bottom surface of the container 100. Both sides of the damper 532 in the longitudinal direction may be rotatably connected to the partition member 300 through a rotation axis. The width direction of the damper 532 is perpendicular (or substantially perpendicular) to the ventilation hole 400, so that the damper 532 can open the ventilation hole 400. The damper 532 may rotate in a first direction (clockwise direction based on Figure 16 ) and thus the damper 532 may have an inner surface facing the ventilation hole 400 and thus closing the ventilation hole 400.

[0130] The damper 532 may include a plurality of dampers 532. The plurality of dampers 532 may be spaced apart from each other by a predetermined distance in the vertical direction. The sum of the areas of the plurality of dampers 532 may be greater than the area of the ventilation hole 400. In one or more embodiments, when closing the ventilation hole 400, some regions of a pair of adjacent dampers 532 may overlap each other. Therefore, when the plurality of dampers 532 rotate sufficiently in a first direction (e.g., Figure 16 clockwise direction), the plurality of dampers 532 may close the ventilation hole 400 without any gaps.

[0131] The fireproof coating can be applied to the surface of the damper 532 to prevent (or at least mitigate) damage caused by heat in case of a fire.

[0132] The adjusting member 533 is connected to the damping member 531 and is configured to selectively allow the damping member 531 to rotate in a first direction in response to a temperature change. That is, in response to no temperature change, the adjusting member 533 can restrict the rotation of the damping member 531 in the first direction so that the ventilation hole 400 remains in an open state. Further, in response to the adjusting member 533 (e.g., by a flame, etc.) being heated to a set temperature or higher, the adjusting member 533 can allow the damping member 531 to rotate in the first direction so that the ventilation hole 400 is closed.

[0133] The adjusting member 533 according to the present embodiment may include a rod 534 and a rope 535.

[0134] The rod 534 is connected to the damping member 531 and applies a rotational force to the damping member 531 in the first direction. In response to no external force being applied to the damping member 531, the rod 534 can rotate the damping member 531 in the first direction under its own weight.

[0135] The rod 534 according to the present embodiment may be formed to have a substantially rod shape. The rod 534 can be integrally coupled to the edge surface of the damper 532 by welding, bolting, etc. A plurality of dampers 532 can be arranged in the longitudinal direction of the rod 534. Each damper 532 can be coupled to a different position of the rod 534 in the longitudinal direction of the rod 534. Therefore, the rod 534 can synchronize the operations of the plurality of dampers 532, that is, the rotational speed, rotational direction, rotational angle, etc. of the plurality of dampers 534. The rod 534 can be provided as a pair of rods 534. The pair of rods 534 can be spaced apart from each other in the longitudinal direction of the damper 532, and they can be coupled to both sides of the damper 532 in the longitudinal direction.

[0136] The rope 535 is connected to the container 100 and the rod 534 and applies a rotational force to the damping member 531 in a second direction opposite to the first direction. That is, the rope 535 can be used as a component that cancels the rotational force in the first direction applied to the damping member 531 by the weight of the rod 534 due to the tension on the rope 535. Therefore, in response to no fire occurring, the damping member 531 can keep the ventilation hole 400 in an open state.

[0137] In response to the rope 535 being heated to a set temperature or higher due to contact with a flame or smoke, the rope 535 can be cut. Therefore, when a fire occurs, the rope 535 can release the rotational force acting on the damping member 531 in a second direction opposite to the first direction, and guide the damping member 531 to rotate in the first direction. The set temperature can be any suitable temperature within the temperature range capable of cutting the rope 535 in response to a fire occurring in the accommodation portion 200.

[0138] The rope 535 can be above the accommodation portion 200, and when a fire occurs, relatively high-temperature air, smoke, etc. can be concentrated in the accommodation portion 200 due to convection. In one or more embodiments, the rope 535 can be supported on the top surface of the container 100 by a clamp (not illustrated) or the like. Therefore, even when the rope 535 is not in direct contact with the flame due to the volume of the accommodation portion 200 itself, the rope 535 can be quickly cut.

[0139] The rope 535 can pass through the upper end portion of the rod 534, and both sides thereof can be inside the adjacent accommodation portions 200. Therefore, the rope 535 can be cut due to a fire occurring in any one of the pair of adjacent accommodation portions 200 only.

[0140] The ropes 535 provided in different blocking members 500 can be connected to each other. In Figure 15 the illustrated embodiment, when three accommodation portions 200 are arranged in a row, a pair of blocking members 500 that respectively open or close the ventilation holes 400 formed in different partition members 300 can be respectively installed on both sides of the accommodation portion 200 provided at the center of the three accommodation portions 200. Both sides of the rope 535 provided in each blocking member 500 can be inside the adjacent accommodation portions 200. Therefore, one end portion of the ropes 535 provided on different blocking members 500 can be inside the accommodation portion 200 located at the center at the same time and can be connected to each other. Therefore, in response to a fire occurring in any one of the plurality of accommodation portions 200, the plurality of blocking members 500 can simultaneously close the ventilation holes 400 formed in different partition members 300.

[0141] Hereinafter, the operation of the energy storage system according to the third embodiment of the present disclosure will be described.

[0142] Figure 18 and Figure 19 are views schematically illustrating the operation process of the energy storage system according to the third embodiment of the present disclosure.

[0143] Reference Figure 18, in response to no fire occurring, the rotational force applied to the damper 532 by the rod 534 in the first direction is canceled out by the tension of the rope 535 in a second direction different from the first direction (e.g., opposite to the first direction).

[0144] Therefore, the damper 532 maintains its state where the width direction is perpendicular (or substantially perpendicular) to the ventilation hole 400, and the ventilation hole 400 remains in the open state.

[0145] Since the ventilation hole 400 remains in the open state, the air A flowing inside any one of the accommodation portions 200 can receive the flow force from the air conditioner 20, and thus the air A can be transmitted through the ventilation hole 400 to the inside of the adjacent accommodation portion 200.

[0146] Reference Figure 19 , in response to a fire occurring in any one of the accommodation portions 200 due to a failure of the battery rack 10 or the air conditioner 20, the flame C or the smoke B contacts the rope 535, and the temperature of the rope 535 increases.

[0147] Thereafter, in response to the rope 535 being heated to a set temperature or higher, the rope 535 is cut.

[0148] In response to the rope 535 being cut, the tension applied to the damper 532 by the rope 535 is released, and the damper 532 rotates in the first direction due to the weight of the rod 534.

[0149] The rotation of the damper 532 in the first direction closes the ventilation hole 400.

[0150] When the ventilation hole 400 is completely closed, the flame C and the smoke B generated inside the accommodation portion 200 cannot be introduced into the ventilation hole 400, thereby blocking the spread of the fire through the ventilation hole 400.

[0151] Hereinafter, the configuration of the energy storage system according to the fourth embodiment of the present disclosure will be described.

[0152] Figure 20 For a perspective view schematically illustrating the configuration of the energy storage system according to the fourth embodiment of the present disclosure, Figure 21 For a front view schematically illustrating the configuration of the energy storage system according to the fourth embodiment of the present disclosure, and Figure 22 For a plan view schematically illustrating the configuration of the energy storage system according to the fourth embodiment of the present disclosure.

[0153] Reference Figures 20 - 22 , the energy storage system according to the present embodiment includes a container 100, at least one accommodation portion 200, at least one partition 300, at least one ventilation hole 400, and at least one blocking member 500.

[0154] The energy storage system according to the fourth embodiment of the present disclosure may be configured to be different from the energy storage system according to the first embodiment of the present disclosure only in the detailed configuration of the blocking member 500.

[0155] Therefore, when describing the energy storage system according to the fourth embodiment of the present disclosure, only the detailed configuration of the blocking member 500 that is not described in the energy storage system according to the first embodiment of the present disclosure will be described.

[0156] The description of the energy storage system according to the first embodiment of the present disclosure can be directly applied to the remaining components of the energy storage system according to the fourth embodiment of the present disclosure.

[0157] Reference Figures 20 - 22 , the blocking member 500 according to the present embodiment may include a movable partition 541, a movable hole 542, and a rope 543.

[0158] The movable partition 541 faces the partition 300 and is movable between a first position and a second position.

[0159] Figure 23 For a perspective view schematically illustrating the state of the movable partition in the first position according to the fourth embodiment of the present disclosure, and Figure 24 For schematically illustrating the state of the movable partition in the second position according to the fourth embodiment of the present disclosure.

[0160] Reference Figures 20 - 24 , the movable partition 541 according to the present embodiment may have a substantially flat plate shape and may be parallel to (or substantially parallel to) the partition 300. The inner surfaces of both the movable partition 541 and the partition 300 may face each other. A fire-resistant coating may be on the outer surface of the movable partition 541 to prevent (or at least mitigate) damage caused by heat in case of a fire.

[0161] The movable partition 541 may be configured to move up and down in a direction perpendicular to (or substantially perpendicular to) the bottom surface of the container 100. In one or more embodiments, the height of the movable partition 541 may be less than the height of the partition 300. The state where the movable partition 541 is in the second position may be a state where the movable partition 541 has completely descended and is in contact with the bottom surface of the container 100. Further, the state where the movable partition 541 is in the first position may be a state where the movable partition 541 has risen to a predetermined height above the second position. In response to no separate external force being applied, the movable partition 541 may be in the second position by its own weight.

[0162] The movable hole 542 passes through the movable partition 541 and is selectively connected (e.g., aligned) in combination with the movement of the movable partition 541 to the ventilation hole 400. In response to the movable partition 541 being in the first position, the movable hole 542 can face the ventilation hole 400 and, in combination with the ventilation hole 400, allow air to move through the ventilation hole 400. When the movable partition 541 is in the second position, the movable hole 542 can be misaligned with the ventilation hole 400 and thus can block (or at least mitigate) the movement of air, flame, or smoke through the ventilation hole 400.

[0163] The movable hole 542 can include a plurality of movable holes 542. When the movable partition 541 is in the first position, the plurality of movable holes 542 can face the plurality of ventilation holes 400. The movable hole 542 can have a shape corresponding (e.g., matching or substantially matching) to the shape of the ventilation hole 400.

[0164] The cord 543 is connected to the container 100 and the movable partition 541 and is configured to selectively allow the movable partition 541 to move from the first position to the second position in response to a temperature change.

[0165] In response to no temperature change, the cord 543 can serve as a component that positions the movable partition 541 in the first position by counteracting the weight of the movable partition 541 through its own tension. Thus, in response to no fire occurring, the ventilation hole 400 can remain in the open state.

[0166] Further, in response to the cord 543 being heated to a set temperature or higher by a flame or the like, the cord 543 can be cut. Thus, the cord 543 releases the tension applied to the movable partition 541 during a fire, causing the movable partition 541 to move to the second position under its own weight and close the ventilation hole 400. The set temperature can be any suitable temperature within a temperature range capable of cutting the cord 543 in response to a fire occurring in the accommodation portion 200.

[0167] The cord 543 can be above the accommodation portion 200, where relatively high-temperature air, smoke, etc. concentrate in the accommodation portion 200 due to convection during a fire. In one or more embodiments, the cord 543 can be supported on the top surface of the container 100 by a clamp or the like. Thus, even in a case where the cord 543 is not in direct contact with the flame due to the volume of the accommodation portion 200 itself, the cord 543 can be quickly cut.

[0168] The cord 543 can pass through the upper end portion of the movable partition 541, and both sides thereof can be inside the adjacent accommodation portion 200. Thus, the cord 543 can be cut by a fire occurring in any one of the pair of adjacent accommodation portions 200.

[0169] The ropes 543 provided in different blocking members 500 may be connected to each other. In Figure 22 In the illustrated embodiment, when three accommodating portions 200 are arranged in a row, a pair of blocking members 500 that respectively open or close the ventilation holes 400 formed in different partition members 300 may be respectively installed on both sides of the accommodating portion 200 provided at the center of the three accommodating portions 200. Both sides of the rope 543 in each blocking member 500 may be inside the adjacent accommodating portion 200, so one end portion of the ropes 543 provided on different blocking members 500 may be simultaneously inside the central accommodating portion 200 and may be connected to each other. Accordingly, in response to a fire occurring in any one of the plurality of accommodating portions 200, the plurality of blocking members 500 may simultaneously close the ventilation holes 400 in different partition members 300.

[0170] The blocking member 500 according to the present embodiment may further include guide rails 544 that guide the movement of the movable partition 541. The guide rails 544 may be provided as a pair of guide rails 544. The pair of guide rails 544 may be on both sides of the partition member 300 and the movable partition 541.

[0171] Figure 25 is an enlarged view schematically illustrating the configuration of the guide rail according to the fourth embodiment of the present disclosure, and Figure 26 is a cross-sectional view schematically illustrating the configuration of the guide rail according to the fourth embodiment of the present disclosure.

[0172] Referring to Figures 20 - 26 , the guide rail 544 according to the present embodiment may include a guide body 544a, a first extension portion 544b, and a second extension portion 544c.

[0173] The guide body 544a is fixed to the container 100 and supports the first extension portion 544b and the second extension portion 544c, which will be described below. The guide body 544a according to the present embodiment may have a flat column shape. The upper end portion and the lower end portion of the guide body 544a may be respectively fixed to the top surface and the bottom surface of the container 100. The guide body 544a may be perpendicular to (or substantially perpendicular to) the partition member 300 and the movable partition 541. The inner surface of the guide body 544a may face the side surfaces of both the partition member 300 and the movable partition 541.

[0174] The first extension portion 544b may extend from one end portion of the guide body 544a and may face the outer surface of the partition member 300. The first extension portion 544b may be fixed to the outer surface of the partition member 300 by welding, bolt connection, etc.

[0175] The second extension part 544c extends from the other end part of the guide body 544a and faces the outer surface of the movable partition 541. The outer surface of the movable partition 541 can be in sliding contact with the second extension part 544c. Accordingly, the relative angle and distance of the movable partition 541 with respect to the partition 300 can be kept constant (or substantially constant) when moving to the first position and the second position.

[0176] Hereinafter, the operation of the energy storage system according to the fourth embodiment of the present disclosure will be described.

[0177] Figure 27 and Figure 28 is a view schematically illustrating the operation process of the energy storage system according to the fourth embodiment of the present disclosure.

[0178] Referring to Figure 27 , in response to no fire occurring, the tension caused by the rope 543 counteracts the weight of the movable partition 541, and thus the movable partition 541 remains in the first position.

[0179] Accordingly, the movable hole 542 faces the ventilation hole 400 (e.g., is aligned with the ventilation hole 400), and the ventilation hole 400 remains in an open state.

[0180] When the ventilation hole 400 remains in the open state, the air A flowing inside any one of the accommodation parts 200 can receive the flow force from the air conditioner 20, and thus the air A can be transmitted through the ventilation hole 400 to the inside of the adjacent accommodation part 200.

[0181] Referring to Figure 28 , in response to a fire occurring in any one of the accommodation parts 200 due to a failure of the battery rack 10 or the air conditioner 20, the flame C or the smoke B contacts the rope 543, and the temperature of the rope 543 increases.

[0182] Thereafter, in response to the rope 543 being heated to a set temperature or higher, the rope 543 is cut off.

[0183] In response to the rope 543 being cut off, the tension applied by the rope 543 to the movable partition 541 is released, and the movable partition 541 moves to the second position under the action of its own weight.

[0184] In response to the movable partition 541 moving to the second position, the movable hole 542 is not aligned with the ventilation hole 400, and the ventilation hole 400 is closed.

[0185] When the ventilation hole 400 is completely closed, the flame C and the smoke B generated inside the accommodation part 200 cannot be introduced into the ventilation hole 400, and thus the spread of the fire through the ventilation hole 400 can be blocked (or at least mitigated).

[0186] According to the present disclosure, by allowing air inside any one of the accommodating portions to be transmitted to an adjacent accommodating portion through the ventilation holes under normal operating conditions, the internal environments of the plurality of accommodating portions can be uniformly maintained.

[0187] According to the present disclosure, by blocking the transmission of flames or smoke generated in any one of the accommodating portions to an adjacent accommodating portion through the ventilation holes in the event of a fire, the spread of fire to the entire area of the container can be prevented.

[0188] However, the effects obtainable by the present disclosure are not limited to the above effects, and other technical effects not mentioned will be clearly understood by those skilled in the art from the description of the present disclosure.

[0189] Although the present disclosure has been described with reference to the embodiments shown in the drawings, these embodiments are merely illustrative, and it should be understood that those skilled in the art can derive various modified and equivalent other embodiments based on the embodiments.
