Technical Field
[0001] Aspects of embodiments of the present disclosure relate to energy storage systems. Background Art
[0002] Generally, an energy storage system (ESS) is a device capable of storing surplus electricity or electricity generated using renewable energy. The energy storage system can be constructed by mounting 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 in various structures.

[0050] 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 meaning or dictionary meaning, and should be construed as having a meaning and concept consistent with the technical idea of the present disclosure based on the principle that the inventor can be his own lexicographer to appropriately define the terms.
[0051] 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 of the technical ideas, aspects, and features of the present disclosure. Accordingly, it will be understood that various equivalents and modifications that may replace or modify the embodiments described herein may exist at the time of filing this application.
[0052] It will be understood that when an element or layer is referred to as being “on,” “connected to,” or “coupled to” another element or layer, the element or layer may be directly on, directly connected to, or directly coupled to the other element or layer, or there may also be one or more intervening 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 intervening elements or layers. For example, when a first element is described as being “coupled” or “connected” to a second element, the first element may be directly coupled or connected to the second element, or the first element may be indirectly coupled or connected to the second element via one or more intervening elements.
[0053] In the drawings, for clarity of illustration, the dimensions of various elements, layers, etc. may be exaggerated. Like reference numerals denote like 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 describing embodiments of the present disclosure, the use of “may” relates to “one or more embodiments of the present disclosure.” When following a list of elements, expressions such as “at least one of” and “any of” modify the entire list of elements and not individual elements 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 among 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 (e.g., 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 to be equivalent to the terms “utilize” and “be utilized,” respectively. As used herein, the terms “substantially,” “about,” and similar terms are used as approximate terms and not as terms of degree, and are intended to account for the inherent deviations of measured or calculated values that would be recognized by a person of ordinary skill in the art.
[0054] It will be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Thus, a first element, component, region, layer or part discussed below may be referred to as a second element, component, region, layer or part without departing from the teachings of the exemplary embodiments.
[0055] For ease of description, spatially relative terms such as "below", "beneath", "lower", "above", and "upper" may be used herein to describe the relationship of one element or feature shown in the figures to another (other) element or feature. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the term "below" can encompass both an upper and a lower orientation. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.
[0056] The terms used herein are for the purpose of describing embodiments of the present disclosure and are not intended to limit the present disclosure. As used herein, the singular form "a" is also intended to include the plural form unless the context clearly indicates otherwise. It will be further understood that when used in this specification, the terms "comprises", "comprising", "contains" and / or "having" specify the presence of the stated 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.
[0057] In addition, any numerical range disclosed and / or recited herein is intended to include all sub-ranges having the same numerical precision as contained within the recited range. For example, the range "1.0 to 10.0" is intended to include all sub-ranges between the recited minimum value 1.0 and the recited maximum value 10.0 (and including the recited minimum value 1.0 and the recited maximum value 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 limitation recited herein is intended to include all lower numerical limitations contained therein, and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations contained therein. Accordingly, the applicant reserves the right to amend the present application document, including the claims, to expressly recite any sub-ranges contained within the ranges expressly recited herein.
[0058] A reference to two comparative elements, features, etc. as "the same" may mean that they are "substantially the same". Thus, the phrase "substantially the same" may include cases having a deviation considered low in the art (e.g., a deviation of less than 5%). In addition, when a certain parameter is said to be uniform in a given region, this may mean that it is uniform in terms of the average value.
[0059] Throughout the specification, each element may be singular or plural unless otherwise stated.
[0060] When any element is said to be disposed (or positioned or located) "above (or below)" or "on (or beneath)" 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 also mean that another component may be interposed between the component and the any element disposed (or positioned or located) on (or beneath) the component.
[0061] In addition, it will be understood that when an element is said to be "coupled", "connected" or "joined" to another element, these elements may be directly "coupled", "connected" or "joined" to each other, or one or more intermediate elements may be present between the element and the other element, and the element may be "coupled", "connected" or "joined" to the other element through these intermediate elements. In addition, when a part is said to be "electrically connected" to another part, the part may be directly electrically connected to the other part, or one or more intermediate components may be present between the part and the other part such that the part and the other part are indirectly electrically connected to each other.
[0062] Throughout the specification, when stating "A and / or B", it means A, B, or A and B, unless otherwise stated. That is, "and / or" includes any or all combinations of the recited multiple items. When stating "C to D", it means C or more and D or less, unless otherwise stated.
[0063] The terms used in this specification are for describing embodiments of the present disclosure and are not intended to limit the present disclosure.
[0064] Figure 1 is a schematic perspective view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 2 is a schematic front view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 3 is a schematic plan view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 4 is a schematic perspective view showing the configuration of a blocking member according to some embodiments of the present disclosure.
[0065] Referring Figures 1 to 4 , according to some embodiments, the energy storage system includes a container 100, a receiving portion 200, a partition wall 300, a ventilation hole 400, and a blocking member 500.
[0066] The container 100 forms an approximate appearance of the energy storage system. The container 100 may be various suitable types of enclosed structures having a hollow interior (e.g., a free-standing building, a room in a building, and a container). In addition to Figure 1 the rectangular parallelepiped shape shown, the shape design of the container 100 may be changed into various shapes (e.g., other polyhedral shapes or cylindrical shapes).
[0067] The receiving portion 200 may be an empty space formed within the container 100. A plurality of receiving portions 200 may be provided. Although Figures 1 to 3 an example in which three receiving portions 200 are formed is shown, the number of receiving portions 200 is not limited thereto, and the design thereof may be changed to various numbers (e.g., two or four).
[0068] The receiving portion 200 may be provided at different positions within the container 100. For example, as Figures 1 to 3 shown, a plurality of receiving portions 200 may be arranged in a row within the container 100. For example, a plurality of receiving portions 200 may be arranged in a grid form within the container 100, or may be vertically stacked within the container 100. The shapes and volumes of the receiving portions 200 may be the same or different from each other.
[0069] Each receiving portion 200 may receive either a battery rack 10 or an air conditioner 20 therein.
[0070] 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 or releasing electric power.
[0071] The air conditioner 20 can be a blower or a general air conditioner (HVAC) device that can adjust the flow rate, temperature, and humidity of the surrounding air.
[0072] The battery rack 10 and the air conditioner 20 can each be accommodated in one of a pair of adjacent accommodation portions 200. For example, referring to Figures 1 to 3 , among the three accommodation portions 200 arranged in a row within the container 100, the air conditioner 20 can be accommodated in the accommodation portion 200 provided in the central portion, and the battery rack 10 can be accommodated in each of the accommodation portions 200 provided beside. However, the arrangement states of the battery rack 10 and the air conditioner 20 are not limited to Figure 1 those depicted in
[0073] The partition wall 300 is provided between a pair of adjacent accommodation portions 200 and separates the pair of adjacent accommodation portions 200 from each other. The partition wall 300 according to some embodiments can be formed to have an approximately flat shape. The partition wall 300 can be provided parallel to the boundary surface between the pair of adjacent accommodation portions 200. The partition wall 300 can be provided such that each of its surfaces faces one of the pair of adjacent accommodation portions 200. The area of the partition wall 300 can be formed to be larger than the area of the boundary surface between the pair of adjacent accommodation portions 200. The partition wall 300 can be made of a non-flammable and fire-resistant material (e.g., concrete, ceramic, or steel) to prevent or substantially reduce damage caused by flames, etc. and contain the fire in case of a fire. A plurality of partition walls 300 can be provided. Each partition wall 300 can be individually provided between the pair of adjacent accommodation portions 200.
[0074] The ventilation holes 400 (e.g., see Figure 4 ) can be formed to pass through the partition wall 300, and each side of the ventilation holes 400 is connected to one of the pair of adjacent accommodation portions 200. That is, the ventilation holes 400 can be used as a path through which air can be transferred from one accommodation portion 200 of the pair of adjacent accommodation portions 200 to the other accommodation portion 200. The design can be variously changed within the range where the area of the ventilation holes 400 is smaller than the area of the partition wall 300. A plurality of ventilation holes 400 can be formed. The plurality of ventilation holes 400 can be provided to be spaced apart from each other in the partition wall 300. The plurality of ventilation holes 400 can be vertically arranged in a row, or can also be arranged in two or more rows. Hereinafter, as Figure 4 shown in
[0075] The blocking member 500 selectively opens or closes the ventilation hole 400 using its driving force. Accordingly, the blocking member 500 can allow the internal air of one accommodation part 200 to be transferred to the adjacent accommodation part 200 through the ventilation hole 400 under normal circumstances, and can block the flames or smoke generated in one accommodation part 200 from being transmitted to the adjacent accommodation part 200 through the ventilation hole 400 in case of a fire. A plurality of blocking members 500 may be provided. The plurality of blocking members 500 may be individually installed for the ventilation holes 400 formed in each partition wall 300.
[0076] Figure 5 is a view showing Figure 4 the state in which the blocking member in some embodiments according to the present disclosure closes the ventilation hole.
[0077] Referring to Figure 4 and Figure 5 , the blocking member 500 according to some embodiments may include a damper member 511 and an actuator 513.
[0078] The damper member 511 may be rotatably connected to the partition wall 300 and may open or close the ventilation hole 400 according to the rotation direction. For example, the damper member 511 may rotate in a first direction to close the ventilation hole 400 and may rotate in a direction opposite to the first direction to open the ventilation hole 400. Here, the first direction may be the clockwise direction or the counterclockwise direction with respect to the rotation axis of the damper member 511.
[0079] The damper member 511 according to some embodiments may include a plurality of dampers 512.
[0080] The damper 512 may be formed in a flat plate shape. The longitudinal direction (or length direction) of the damper 512 may be parallel to the bottom surface of the container 100. Both sides of the damper 512 in the longitudinal direction may be rotatably connected to the partition wall 300 through a rotation axis. Since the transverse direction (or width direction) of the damper 512 is perpendicular to the ventilation hole 400, the damper 512 can open the ventilation hole 400. In this state, when the damper 512 rotates in a first direction (e.g., Figure 4 and Figure 5 the clockwise direction in) the inner surface of the damper 512 may be set to face the ventilation hole 400, and the ventilation hole 400 may be closed.
[0081] A plurality of dampers 512 may be provided. The plurality of dampers 512 may be arranged to be vertically spaced apart from each other at a certain interval. The sum of the areas of the plurality of dampers 512 may be greater than the area of the ventilation hole 400. In this case, when an adjacent pair of dampers 512 closes the ventilation hole 400, the adjacent pair of dampers 512 may be arranged such that at least a partial region thereof overlaps with each other. Accordingly, when the plurality of dampers 512 are sufficiently rotated in the first direction, the dampers 512 may close the ventilation hole 400 without any gap.
[0082] Fireproof coating may be applied to the surface of the damper 512 to prevent or substantially reduce thermal damage in case of a fire.
[0083] The actuator 513 is connected to the damper member 511 and may generate a rotational force to control the rotational direction of the damper member 511. The actuator 513 according to some embodiments may include a motor that receives power from the outside to generate a rotational force and a power transmission member (e.g., a gear or a pulley) that is connected to the motor and transmits the rotational force of the motor to the damper member 511.
[0084] The motors may be formed in a number corresponding to the number of the plurality of dampers 512, or may be formed singly (e.g., a single motor may be provided). The motor may be disposed within the accommodation part 200, or may be disposed outside the container 100.
[0085] The power transmission members may be individually connected to the rotation shafts of the plurality of dampers 512. The power transmission members may receive the rotational force from the motor, thereby rotating the plurality of dampers 512 simultaneously at the same angular velocity.
[0086] The energy storage system according to some embodiments may further include a fire extinguishing member 600 (e.g., see Figure 1 ).
[0087] When a fire has occurred in the accommodation part 200, the fire extinguishing member 600 sprays a fire extinguishing liquid into the accommodation part 200. That is, the fire extinguishing member 600 may serve as a component for extinguishing the fire generated in the accommodation part 200 in case of a fire.
[0088] The fire extinguishing member 600 according to some embodiments may include a storage part 610 that stores a fire extinguishing liquid and a spray pipeline 620 that extends from the storage part 610 into the accommodation part 200.
[0089] The storage part 610 may be various suitable types of storage containers capable of storing a fire extinguishing liquid.
[0090] The injection pipeline 620 may be a pipe having one side connected to the storage part 610 and the other side passing through the container 100 and disposed within the accommodation part 200. In the injection pipeline 620, a pump for supplying the fire extinguishing liquid stored in the storage part 610 to the injection pipeline 620 may be installed, and a nozzle for injecting the fire extinguishing liquid flowing along the injection pipeline 620 into the accommodation part 200 may be installed. A plurality of injection pipelines 620 may be provided. The plurality of injection pipelines 620 may be individually disposed within one of the accommodation parts 200.
[0091] Figure 6 is a schematic block diagram showing the configuration of an energy storage system according to some embodiments of the present disclosure.
[0092] Reference Figures 1 to 3 and Figure 6 , according to some embodiments, the energy storage system may further include a detection member 700 and a controller 800.
[0093] The detection member 700 collects environmental data within the accommodation part 200. Here, the environmental data may include information about the internal temperature of the accommodation part 200 (i.e., the temperature within the accommodation part 200) and information about the presence of smoke.
[0094] According to some embodiments, the detection member 700 may include a temperature sensor 710 and a smoke sensor 720.
[0095] The temperature sensor 710 detects the internal temperature of the accommodation part 200. According to some embodiments, the temperature sensor 710 may be a thermal sensor or an infrared sensor capable of detecting temperature, etc. A plurality of temperature sensors 710 may be provided. The plurality of temperature sensors 710 may be individually installed within each accommodation part 200. The plurality of temperature sensors 710 may be installed within each accommodation part 200. As an example, as Figures 1 to 3 shown, two temperature sensors 710 may be installed within each accommodation part 200.
[0096] The smoke sensor 720 detects the smoke generated within the accommodation part 200. According to some embodiments, the smoke sensor 720 may be various suitable types of smoke detectors such as an ionization smoke sensor and a photoelectric smoke sensor capable of detecting the smoke generated by combustion. A plurality of smoke sensors 720 may be provided. The plurality of smoke sensors 720 may be individually installed within each accommodation part 200. The plurality of smoke sensors 720 may be installed within each accommodation part 200. As an example, as Figures 1 to 3 shown, two smoke sensors 720 may be installed within each accommodation part 200.
[0097] The controller 800 controls the overall operations of the blocking member 500, the fire extinguishing member 600, and the air conditioner 20. For example, the controller 800 may determine whether a fire has occurred in the accommodation part 200 based on the data detected by the detection member 700, and based on the determined information, the controller 800 may control the operations of the blocking member 500, the fire extinguishing member 600, and the air conditioner 20.
[0098] In addition, the controller 800 may determine whether a fire has occurred in the accommodation part 200 based on the environmental data collected by the detection member 700, and may generate a warning signal or an emergency signal based on the determined information. The warning signal and the emergency signal may be signals that can be distinguished from each other by the user. The warning signal and the emergency signal may include signals such as alarm sounds that can be aurally recognized by the user or signals such as images, lighting, or a combination thereof that can be visually recognized by the user.
[0099] The controller 800 may include an electronic control device that monitors in real time the data detected by the detection member 700 and controls the operations of the blocking member 500, the fire extinguishing member 600, and the air conditioner 20 based on the monitored information. Such an electronic control device may be implemented as an integrated circuit (IC), a microcontroller (μC), a microprocessor, an application-specific integrated circuit (ASIC), or a combination thereof that can control multiple hardware or software components by running an operating system or an application program and can perform various data processing and operations. In addition, the controller 800 may include a visually recognizable lighting device, a display, or an acoustic device configured to generate an aurally recognizable signal.
[0100] Hereinafter, the operations of the energy storage system according to some embodiments of the present disclosure will be described.
[0101] Figure 7 is a schematic flowchart showing an operation process of an energy storage system according to some embodiments of the present disclosure.
[0102] Reference Figures 1 to 7 , the detection member 700 collects environmental data inside the accommodation part 200 (operation S10).
[0103] The controller 800 determines whether a fire has occurred based on the data detected by the detection member 700 (operation S20).
[0104] Figures 8 to 10 is a schematic flowchart showing a process in which a controller determines whether a fire has occurred according to some embodiments of the present disclosure.
[0105] Reference Figure 8 , in operation S20, the controller 800 may determine whether a fire has occurred based on the temperature data detected by the temperature sensor 710 (operation S210).
[0106] For example, the controller 800 determines whether the number of temperature sensors 710 that detect a temperature higher than or equal to the set temperature in any one of the accommodation parts 200 is 1 or more and less than n (operation S211). Here, n can be any one of natural numbers of 2 or more.
[0107] When the number of temperature sensors 710 that detect a temperature higher than or equal to the set temperature in operation S211 is 1 or more and less than n, the controller 800 generates a warning signal (operation S212).
[0108] The controller 800 determines whether the number of temperature sensors 710 that detect a temperature higher than or equal to the set temperature in any one of the accommodation parts 200 is n or more (operation S213). As Figure 1 shown, when two temperature sensors 710 are installed in each accommodation part 200, n can be 2.
[0109] When the number of temperature sensors 710 that detect a temperature higher than or equal to the set temperature in operation S213 is n or more, the controller 800 generates a fire operation signal (operation S214). The fire operation signal can be an electric signal for operating the blocking member 500, the fire extinguishing member 600, and the air conditioner 20.
[0110] Reference Figure 9 , in operation S20, the controller 800 can determine whether a fire has occurred based on the smoke data detected by the smoke sensor 720 (operation S220).
[0111] For example, the controller 800 determines whether the number of smoke sensors 720 that detect smoke in any one of the accommodation parts 200 is 1 or more and less than m (operation S221). Here, m can be any one of natural numbers of 2 or more.
[0112] When the number of smoke sensors 720 that detect smoke in operation S221 is 1 or more and less than m, the controller 800 generates a warning signal (operation S222).
[0113] The controller 800 determines whether the number of smoke sensors 720 that detect smoke in any one of the accommodation parts 200 is m or more (operation S223). As Figure 1 shown, when two smoke sensors 720 are installed in each accommodation part 200, m can be 2.
[0114] When the number of smoke sensors 720 that detect smoke in operation S223 is m or more, the controller 800 generates a fire operation signal (operation S224).
[0115] Reference Figure 10 In operation S20, based on the combination of the temperature data detected by the temperature sensor 710 in one of the accommodation parts 200 and the smoke data detected by the smoke sensor 720, the controller 800 can determine whether a fire has occurred (operation S230).
[0116] That is to say, in operation S230, when the temperature detected by any one of the temperature sensors 710 is higher than or equal to the set temperature and smoke is detected by any one of the smoke sensors 720, the controller 800 can determine that a fire has occurred. In addition, in operation S230, when the temperature detected by any one of the temperature sensors 710 is higher than or equal to the set temperature, or when smoke is detected by any one of the smoke sensors 720, the controller 800 can only generate a warning signal.
[0117] For example, as Figure 10 shown, the controller 800 determines whether the temperature detected by any one of the multiple temperature sensors 710 installed in any one of the accommodation parts 200 is higher than or equal to the set temperature (operation S231).
[0118] When the temperatures detected by all the temperature sensors 710 in operation S231 are lower than the set temperature, the controller 800 determines whether any one of the multiple smoke sensors 720 has detected smoke (operation S232).
[0119] When any one of the smoke sensors 720 has detected smoke in operation S232, the controller 800 generates a warning signal (operation S233).
[0120] When no smoke sensor 720 has detected smoke in operation S232, the controller 800 may not take any action, and operation S230 may be in an end state (ended).
[0121] When the temperature detected by any one of the temperature sensors 710 is higher than or equal to the set temperature in operation S231, the controller 800 determines whether any one of the smoke sensors 720 has detected smoke (operation S234).
[0122] When none of the smoke sensors 720 has detected smoke in operation S234, the controller 800 generates a warning signal (operation S235).
[0123] When any one of the smoke sensors 720 has detected smoke in operation S234, the controller 800 generates a fire operation signal (operation S236).
[0124] The controller 800 may perform all of operations S210, S220, and S230, or may also perform only one of operations S210, S220, and S230 or a combination of two of operations S210, S220, and S230.
[0125] Figure 11 and Figure 12 is a schematic diagram showing an operation process of an energy storage system according to some embodiments of the present disclosure.
[0126] Reference Figure 7 and Figure 11 When in operation S20 the controller 800 determines that a fire has not occurred, the damper 512 maintains its state with its width direction perpendicular to the ventilation hole 400, and the ventilation hole 400 is maintained in an open state.
[0127] When the ventilation hole 400 is maintained in an open state, the air A flowing within one accommodation part 200 can receive a flow force from the air conditioner 20 and be transmitted through the ventilation hole 400 into an adjacent accommodation part 200, and can circulate through a plurality of accommodation parts 200.
[0128] Reference Figure 7 and Figure 12 When in operation S20 the controller 800 determines that a fire has occurred, the controller 800 transmits a fire operation signal to the air conditioner 20 to stop the operation of the air conditioner 20 (operation S30).
[0129] The controller 800 may transmit a fire operation signal to the actuator 513 to close the ventilation hole 400 (operation S40).
[0130] For example, when receiving the fire operation signal from the controller 800, the actuator 513 may generate a rotational force, and the damper 512 rotates in a first direction.
[0131] The damper 512 rotates in the first direction and closes the ventilation hole 400.
[0132] When the ventilation hole 400 is completely closed, the flame C and smoke B generated within the accommodation part 200 may not flow into the ventilation hole 400, and the spread of fire through the ventilation hole 400 can be blocked.
[0133] The controller 800 may transmit a fire operation signal to the fire extinguishing member 600, and the fire extinguishing member 600 may spray a fire extinguishing liquid into the accommodation part 200 to extinguish the fire within the accommodation part 200 (operation S50). In this case, the controller 800 may control the operation of the pump such that the fire extinguishing liquid is only supplied to the injection pipeline 620 disposed within the accommodation part 200 in which a fire has been determined to have occurred among the plurality of injection pipelines 620.
[0134] When the controller 800 determines that a fire has occurred, the controller 800 may generate an emergency signal (operation S60).
[0135] Hereinafter, the configuration of the energy storage system according to some other embodiments of the present disclosure will be described.
[0136] Figure 13 is a schematic perspective view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 14 is a schematic front view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 15 is a schematic plan view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 16 is a schematic perspective view showing the configuration of a blocking member according to some embodiments of the present disclosure. Figure 17 is showing according to some embodiments of the present disclosure Figure 16 a perspective view of the state in which the blocking member in closes the ventilation hole.
[0137] Reference Figures 13 to 17 , the energy storage system according to some embodiments includes a container 100, a receiving part 200, a partition wall 300, a ventilation hole 400, a blocking member 500, a fire extinguishing member 600, a detection member 700, and a controller 800.
[0138] The energy storage system according to some embodiments of the present disclosure may be configured to differ only in the detailed configuration of the blocking member 500 from the energy storage system according to some embodiments of the present disclosure described previously.
[0139] Accordingly, when describing the energy storage system according to some embodiments of the present disclosure, only the detailed configuration of the blocking member 500 that was not described in the energy storage system according to some embodiments of the present disclosure described previously will be described.
[0140] The description of the energy storage system according to some embodiments of the present disclosure mentioned previously can be applied to the remaining configuration of the energy storage system according to some embodiments of the present disclosure without any change.
[0141] The blocking member 500 according to some embodiments may include a damper member 531, an adjusting member 533, and an actuator 536.
[0142] The damper member 531 may be rotatably connected to the partition wall 300 and may open or close the ventilation hole 400 according to the rotation direction. For example, the damper member 531 may rotate in a first direction to close the ventilation hole 400 and may rotate in a direction opposite to the first direction to open the ventilation hole 400. Here, the first direction may be a clockwise direction or a counterclockwise direction with respect to the rotation axis of the damper member 531.
[0143] The damper member 531 according to some embodiments may include a plurality of dampers 532.
[0144] The damper 532 may be formed in a flat plate shape. The longitudinal direction (or length direction) of the damper 532 may be 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 wall 300 by a rotating shaft. Since the lateral direction (or width direction) of the damper 532 is perpendicular to the ventilation hole 400, the damper 532 may open the ventilation hole 400. In this state, when the damper 532 rotates in the first direction (e.g., Figure 16 and Figure 17 the clockwise direction in), the inner surface of the damper 532 may be set to face the ventilation hole 400, and the ventilation hole 400 may be closed.
[0145] A plurality of dampers 532 may be provided. The plurality of dampers 532 may be arranged to be vertically spaced apart from each other at a certain interval. The sum of the areas of the plurality of dampers 532 may be greater than the area of the ventilation hole 400. In this case, when an adjacent pair of dampers 532 closes the ventilation hole 400, the adjacent pair of dampers 532 may be arranged such that at least a part of their regions overlap each other. Accordingly, when the plurality of dampers 532 rotate sufficiently in the first direction, the dampers 532 may close the ventilation hole 400 without any gaps.
[0146] A fireproof coating may be applied to the surface of the damper 532 to prevent or substantially reduce thermal damage in the event of a fire.
[0147] The adjusting member 533 is connected to the damper member 531 and selectively allows the damper member 531 to rotate in the first direction according to a temperature change. That is, when there is no separate temperature change, the adjusting member 533 may restrict the damper member 531 from rotating in the first direction so that the ventilation hole 400 is kept open. In addition, when heated above a set temperature by a flame or the like, the adjusting member 533 may allow the damper member 531 to rotate in the first direction so that the ventilation hole 400 is closed.
[0148] The adjusting member 533 according to some embodiments may include a rod 534 and a rope 535.
[0149] The rod 534 is connected to the damper member 531 and applies a rotational force to the damper member 531 in the first direction. That is, when no separate external force is applied to the damper member 531, the rod 534 may serve as a component that rotates the damper member 531 in the first direction using its own weight.
[0150] The rod 534 according to some embodiments may be formed to have an approximate rod shape. The rod 534 may be integrally coupled to the edge surface of the damper 532 by welding or bolting. A plurality of dampers 532 may be arranged in the longitudinal direction of the rod 534. The dampers 532 may be coupled to different positions of the rod 534 in the longitudinal direction of the rod 534. Accordingly, the rod 534 may synchronize the operations (i.e., rotational speed, rotational direction, or rotational angle, etc.) of the plurality of dampers 532. A pair of rods 534 may be provided. The pair of rods 534 may be spaced apart from each other in the longitudinal direction of the damper 532 and may be respectively coupled to one of the two sides in the longitudinal direction of the damper 532.
[0151] The rope 535 is connected to the container 100 and the rod 534, and applies a rotational force to the damper member 531 in a direction opposite to the first direction. That is, the rope 535 may be a component that uses its own tension to counteract the rotational force applied to the damper member 531 by the rod 534 in the first direction. Accordingly, when a fire has not occurred, the damper member 531 may keep the ventilation hole 400 in an open state.
[0152] The rope 535 may be cut by the operation of the actuator 536, which will be described below. Accordingly, when a fire occurs, the rope 535 may release the rotational force acting on the damper member 531 in a direction opposite to the first direction and may cause the damper member 531 to rotate in the first direction. The design may be differently changed to change the set temperature within the temperature range in which the rope 535 may be cut when a fire occurs in the accommodation part 200.
[0153] When heated to a temperature above the set temperature due to contact with flames or smoke, the rope 535 may be cut. Accordingly, even when the actuator 536 is damaged or fails, the rope 535 may be cut, thereby further improving the reliability of the fire prevention performance. Here, the set temperature at which the rope 535 is cut may be different from the set temperature detected by the temperature sensor 710.
[0154] The rope 535 may be provided above the accommodation part 200 (where relatively high-temperature air and smoke gather due to convection when a fire occurs). In this case, the rope 535 may be supported on the top surface of the container 100 by a fixture or the like. Accordingly, even in a situation where it is difficult for the rope 535 to directly contact the flames due to the volume of the accommodation part 200 itself, the rope 535 may be quickly cut.
[0155] The rope 535 can pass through the upper end of the rod 534, and both ends of the rope 535 can be respectively disposed in one of the adjacent receiving portions 200. Accordingly, it is possible to prevent the rope 535 from being cut off only by a fire occurring in one of the pair of adjacent receiving portions 200.
[0156] The ropes 535 provided in the different blocking members 500 can be connected to each other. For example, as Figure 15 shown, three receiving portions 200 can be arranged in a row, and thus, a pair of blocking members 500 that separately open or close the ventilation holes 400 formed in the different partition walls 300 can be separately installed on both sides of the receiving portion 200 provided at the central portion. Both ends of the rope 535 provided in each blocking member 500 can be disposed in the adjacent receiving portions 200, and thus, one end of the ropes 535 provided in the different blocking members 500 can be simultaneously disposed in the receiving portion 200 provided at the central portion and connected to each other. Accordingly, when a fire occurs in one of the plurality of receiving portions 200, the plurality of blocking members 500 can simultaneously close the ventilation holes 400 formed in the different partition walls 300.
[0157] The actuator 536 generates a driving force to cut off the rope 535. The actuator 536 according to some embodiments can be an electric cutter that is connected to the rope 535 and can cut off the rope 535 by receiving power from the outside (for example, from the controller 800). A plurality of actuators 536 can be provided. The plurality of actuators 536 can be arranged to be spaced apart from each other in the extending direction of the rope 535.
[0158] Hereinafter, the operation of the energy storage system according to some other embodiments of the present disclosure will be described.
[0159] Figures 18 to 21 is a schematic diagram showing an operation process of the energy storage system according to some embodiments of the present disclosure.
[0160] In some embodiments, the controller 800 performs the same operations as those described in some embodiments of the present disclosure above, and can determine whether a fire has occurred.
[0161] Referring to Figure 18 and Figure 20 , when the controller 800 determines that a fire has not occurred, the rope 535 remains uncut, and the rotational force applied by the rod 534 to the damper 532 in the first direction is offset by the tension of the rope 535.
[0162] Accordingly, the damper 532 can maintain a state in which its width direction is perpendicular to the ventilation hole 400, and the ventilation hole 400 can be maintained in an open state.
[0163] When the ventilation hole 400 is kept open, the air A flowing within an accommodation part 200 can receive a flow force from the air conditioner 20 and be transmitted through the ventilation hole 400 to an adjacent accommodation part 200, and can circulate through a plurality of accommodation parts 200.
[0164] Reference Figure 19 and Figure 21 When the controller 800 determines that a fire has occurred, the controller 800 can generate an emergency signal and transmit a fire operation signal to the air conditioner 20 to stop the operation of the air conditioner 20.
[0165] The controller 800 can transmit the fire operation signal to the actuator 536 to close the ventilation hole 400.
[0166] For example, when receiving the fire operation signal from the controller 800, the actuator 536 cuts the rope 535.
[0167] When the rope 535 is cut, the tension applied to the damper 532 by the rope 535 is released, and the damper 532 rotates in a first direction by the self-weight of the rod 534.
[0168] The damper 532 rotates in the first direction and closes the ventilation hole 400.
[0169] When the ventilation hole 400 is completely closed, the flame C and the smoke B generated within the accommodation part 200 may not flow into the ventilation hole 400, and the fire spread through the ventilation hole 400 can be blocked.
[0170] When the rope 535 is not properly cut due to damage or malfunction of the actuator 536, the rope 535 can be cut by being heated to a temperature above a set temperature by contact with the flame C or the smoke B generated within the accommodation part 200.
[0171] In addition, the controller 800 transmits the fire operation signal to the fire extinguishing member 600, and the fire extinguishing member 600 sprays a fire extinguishing liquid into the accommodation part 200 to extinguish the fire within the accommodation part 200. In this case, the controller 800 can control the operation of the pump so that the fire extinguishing liquid is only supplied to the injection pipeline 620 provided within the accommodation part 200 in which a fire has been determined to have occurred among the plurality of injection pipelines 620.
[0172] Hereinafter, the configuration of an energy storage system according to some other embodiments of the present disclosure will be described.
[0173] Figure 22 is a schematic perspective view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 23is a schematic front view showing the configuration of an energy storage system according to some embodiments of the present disclosure. Figure 24 is a schematic plan view showing the configuration of an energy storage system according to some embodiments of the present disclosure.
[0174] Reference Figures 22 to 24 , according to some embodiments, the energy storage system includes a container 100, a receiving portion 200, a partition wall 300, a ventilation hole 400, a blocking member 500, a fire extinguishing member 600, a detection member 700, and a controller 800.
[0175] The energy storage system according to some embodiments of the present disclosure may be configured to differ only in the detailed configuration of the blocking member 500 from the energy storage system according to some embodiments of the present disclosure described previously.
[0176] Accordingly, when describing the energy storage system according to some embodiments of the present disclosure, only the detailed configuration of the blocking member 500 that is not described in the previously described energy storage system according to some embodiments of the present disclosure will be described.
[0177] The previously mentioned description of the energy storage system according to some embodiments of the present disclosure may be applied to the configuration of the energy storage system according to some embodiments of the present disclosure without any change.
[0178] According to some embodiments, the blocking member 500 may include a movable partition wall 541, a movable hole 542, a rope 543, and an actuator 545.
[0179] The movable partition wall 541 is disposed to face the partition wall 300 and is mounted to be movable between a first position and a second position.
[0180] Figure 25 is a schematic perspective view showing the state in which the movable partition wall according to some embodiments of the present disclosure is disposed at the first position. Figure 26 is a schematic perspective view showing the state in which the movable partition wall according to some embodiments of the present disclosure is disposed at the second position.
[0181] Reference Figures 22 to 26 , according to some embodiments, the movable partition wall 541 may be formed in a substantially flat plate shape and may be disposed parallel to the partition wall 300. The inner surface of the movable partition wall 541 and the inner surface of the partition wall 300 may be disposed to face each other. A fireproof coating may be applied to the outer surface of the movable partition wall 541 to prevent or substantially reduce thermal damage in the event of a fire.
[0182] The movable partition wall 541 can be installed to be liftable in a direction perpendicular to the bottom surface of the container 100. In this case, the height of the movable partition wall 541 can be formed to be less than the height of the partition wall 300. Here, the state in which the movable partition wall 541 is located at the second position can be a state in which the movable partition wall 541 is fully lowered to contact the bottom surface of the container 100. In addition, the state in which the movable partition wall 541 is located at the first position can be a state in which the movable partition wall 541 is lifted from the second position to a specific level. When no separate external force is applied, the movable partition wall 541 can be located at the second position by its own weight.
[0183] The movable hole 542 is formed to pass through the movable partition wall 541 and selectively communicate with the ventilation hole 400 as the movable partition wall 541 moves. For example, when the movable partition wall 541 is located at the first position, the movable hole 542 can be set to face the ventilation hole 400 and can communicate with the ventilation hole 400 to allow air to flow through the ventilation hole 400. When the movable partition wall 541 is located at the second position, the movable hole 542 can be set to be misaligned with the ventilation hole 400 and can block air, flames, or smoke from flowing through the ventilation hole 400.
[0184] A plurality of movable holes 542 can be formed. When the movable partition wall 541 is located at the first position, each of the plurality of movable holes 542 can be set to individually face one ventilation hole 400. The shape of the movable hole 542 can be a shape corresponding to the shape of the ventilation hole 400.
[0185] The rope 543 is connected to the container 100 and the movable partition wall 541. The rope 543 can be used as a component that positions the movable partition wall 541 at the first position by utilizing its tension to counteract the weight of the movable partition wall 541. Accordingly, when no fire occurs, the ventilation hole 400 can be kept open.
[0186] The rope 543 can be cut by the operation of the actuator 545, which will be described below. Accordingly, when a fire occurs, the rope 543 can release the tension applied to the movable partition wall 541, thereby causing the movable partition wall 541 to move to the second position by its own weight to close the ventilation hole 400.
[0187] In addition, the rope 543 can be cut when heated to a temperature above a set temperature by a flame or the like. Accordingly, even when the actuator 545 is damaged or fails, the rope 543 can be cut, thereby further improving (e.g., increasing) the reliability of the fire prevention performance. Here, the set temperature at which the rope 543 is cut can be different from the set temperature detected by the temperature sensor 710.
[0188] The rope 543 may be disposed above the accommodation part 200 (where relatively high-temperature air and smoke gather due to convection in case of a fire). In this case, the rope 543 may be supported on the top surface of the container 100 by a clamp or the like. Accordingly, even in a situation where it is difficult for the rope 543 to be in direct contact with the flame due to the volume of the accommodation part 200 itself, the rope 543 can be quickly cut off.
[0189] The rope 543 may pass through the upper end of the movable partition wall 541, and both ends of the rope 543 may be respectively disposed in one of the adjacent accommodation parts 200. Accordingly, it is possible to prevent the rope 543 from being cut off only by a fire occurring in one of the pair of adjacent accommodation parts 200.
[0190] The ropes 543 provided in the different blocking members 500 may be connected to each other. For example, as Figure 23 shown, three accommodation parts 200 may be arranged in a row, and thus, a pair of blocking members 500 that separately open and close the ventilation holes 400 formed in the different partition walls 300 may be separately installed on both sides of the accommodation part 200 provided at the central part. Both ends of the rope 543 provided in each blocking member 500 may be disposed in the adjacent accommodation parts 200, and thus, one end of the ropes 543 provided in the different blocking members 500 may be simultaneously disposed in the accommodation part 200 provided at the central part and connected to each other. Accordingly, when a fire occurs in one of the plurality of accommodation parts 200, the plurality of blocking members 500 may simultaneously close the ventilation holes 400 formed in the different partition walls 300.
[0191] The actuator 545 generates a driving force to cut off the rope 543. The actuator 545 according to some embodiments may be an electric cutter connected to the rope 543 and capable of cutting off the rope 543 by receiving power from the outside. A plurality of actuators 545 may be provided. The plurality of actuators 545 may be arranged to be spaced apart from each other in the extending direction of the rope 543.
[0192] The blocking member 500 according to some embodiments may further include a guide rail 544 that guides the movement of the movable partition wall 541. A pair of guide rails 544 may be provided. The pair of guide rails 544 may be disposed on both sides of each of the partition wall 300 and the movable partition wall 541.
[0193] Figure 27 is a schematic enlarged view showing the configuration of the guide rail according to some embodiments of the present disclosure. Figure 28 is a schematic cross-sectional view showing the configuration of the guide rail according to some embodiments of the present disclosure.
[0194] ReferenceFigures 22 to 28 According to some embodiments, the guide rail 544 may include a guide body 544a, a first extension portion 544b, and a second extension portion 544c.
[0195] 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 some embodiments may be formed in a flat column shape. The upper end and the lower end of the guide body 544a may be fixed to the top surface and the bottom surface of the container 100, respectively. The guide body 544a may be disposed perpendicular to the partition wall 300 and the movable partition wall 541. The inner surface of the guide body 544a may be disposed to face the side surfaces of each of the partition wall 300 and the movable partition wall 541.
[0196] The first extension portion 544b may extend from one end of the guide body 544a and may be disposed to face the outer surface of the partition wall 300. The first extension portion 544b may be fixed to the outer surface of the partition wall 300 by welding or bolt connection or the like.
[0197] The second extension portion 544c extends from the other end of the guide body 544a and is disposed to face the outer surface of the movable partition wall 541. The outer surface of the movable partition wall 541 may be in slidable contact with the second extension portion 544c. Accordingly, the relative angle and distance of the movable partition wall 541 with respect to the partition wall 300 may remain constant when being moved to the first position and the second position.
[0198] Hereinafter, the operation of the energy storage system according to some other embodiments of the present disclosure will be described.
[0199] Figure 29 and Figure 30 are schematic diagrams showing the operation process of the energy storage system according to some embodiments of the present disclosure.
[0200] In some embodiments, the controller 800 performs the same operations as those described in some embodiments of the present disclosure above, and may determine whether a fire has occurred.
[0201] Referring to Figure 22 and Figure 29 , when the controller 800 determines that no fire has occurred, the rope 543 remains uncut.
[0202] Since the tension of the rope 543 counteracts the weight of the movable partition wall 541, the movable partition wall 541 remains in the state at the first position.
[0203] Accordingly, the movable hole 542 may be disposed to face the ventilation hole 400, and the ventilation hole 400 may be kept open.
[0204] When the ventilation hole 400 is kept open, the air A flowing within one accommodation part 200 can receive a flow force from the air conditioner 20 and be transmitted through the ventilation hole 400 to an adjacent accommodation part 200, and can circulate through the plurality of accommodation parts 200.
[0205] Reference Figure 22 and Figure 30 , when the controller 800 determines that a fire has occurred, the controller 800 can generate an emergency signal and can transmit a fire operation signal to the air conditioner 20 to stop the operation of the air conditioner 20.
[0206] The controller 800 can transmit a fire operation signal to the actuator 545 to close the ventilation hole 400.
[0207] For example, when receiving a fire operation signal from the controller 800, the actuator 545 cuts the rope 543.
[0208] When the rope 543 is cut, the tension applied to the movable partition wall 541 by the rope 543 is released, and the movable partition wall 541 moves to the second position by its own weight.
[0209] When the movable partition wall 541 moves to the second position, the movable hole 542 is set to be misaligned with the ventilation hole 400, and the ventilation hole 400 is closed. In other words, the ventilation hole 400 is blocked by the movable partition wall 541.
[0210] When the ventilation hole 400 is completely closed, the flame C and the smoke B generated within the accommodation part 200 may not flow into the ventilation hole 400, and the fire spread through the ventilation hole 400 can be blocked.
[0211] When the rope 543 is not properly cut due to damage or malfunction of the actuator 545, the rope 543 can be cut by being heated to a temperature above the set temperature by contacting the flame C or the smoke B generated within the accommodation part 200.
[0212] In addition, the controller 800 can transmit a fire extinguishing operation signal to the fire extinguishing member 600, and the fire extinguishing member 600 can spray a fire extinguishing liquid into the accommodation part 200 to extinguish the fire within the accommodation part 200. In this case, the controller 800 can control the operation of the pump so that the fire extinguishing liquid is only supplied to the injection pipe 620 provided within the accommodation part 200 in which a fire has been determined to have occurred among the plurality of injection pipes 620.
[0213] According to the present disclosure, under normal circumstances, the internal air of any one of the accommodating portions can be transferred to the adjacent accommodating portion through the ventilation holes, so as to uniformly maintain the internal environment of the plurality of accommodating portions.
[0214] According to the present disclosure, in the event of a fire, the flames or smoke generated in any one of the accommodating portions are blocked from being transmitted to the adjacent accommodating portion through the ventilation holes, thereby preventing or substantially reducing the spread of the fire to the entire area of the container.
[0215] According to the present disclosure, the controller automatically opens or closes the ventilation holes by controlling the operation of the blocking member based on the data detected by the detection member, thereby ensuring accurate fire prevention performance.
[0216] According to the present disclosure, even when the actuator is damaged or fails, the rope can be cut off by contacting the flames or smoke, thereby further improving the reliability of the fire prevention performance.
[0217] However, the effects obtainable through 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 according to the description of the present disclosure.
[0218] 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 modifications and other equivalent embodiments based on these embodiments.
