Description

TECHNICAL FIELD

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

[0002] Generally, an energy storage system (ESS) is a device capable of storing surplus power or power generated using renewable energy. The energy storage system can be constructed 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 in various structures.

[0003] In the event of a fire of such an energy storage system due to thermal runaway or other electrical defects occurring during a charging or discharging process of a secondary battery, there is a risk that all components within the container are exposed to fire and are burned or damaged. To prevent such a risk, a fire compartment can be constructed by erecting a fire wall that does not allow ventilation in the middle of the container. However, in this case, a separate air conditioning device is required for each compartment, which increases the cost and is disadvantageous in terms of battery energy density.

[0050] In this document, some embodiments of the present disclosure will be described in greater detail with reference to the accompanying drawings. The terms or words used in this specification and claims should not be construed as being limited to the generally-accepted meanings or dictionary definitions, and should be construed as having meanings and concepts consistent with the technology of the present disclosure based on the principle that the inventor can appropriately define the terms in order to appropriately define the concepts of the terms according to the application.

[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, at the time of filing this application, there can be various equivalents and modifications which can replace or modify the embodiments described herein.

[0052] It will be understood that when an element or layer is referred to as being “on” another element or layer, “connected to” or “coupled to” another element or layer, it can be directly on the other element or layer, directly connected to or coupled to the other element or layer, or one or more intervening elements or layers can also be present. In contrast, when an element or layer is referred to as being “directly on” or “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. By way of 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 intervening elements.

[0053] In the drawings, the size of various elements, layers, etc. can be exaggerated for clarity. Like reference numbers signify like elements. As used in this document, the term “and / or” includes any and all combinations of one or more of the associated listed items. In addition, use of “may” when describing embodiments of the present disclosure relates to “one or more embodiments of the present disclosure”. Expressions such as “at least one of,” and “any one of,” when preceding a list of two or more elements, modify the entire list of elements and do not modify the individual elements of the list. When used in the phrases such as “at least one of A, B, and C,” “at least one of a group of items from among A, B, and C,” or “at least one of A, B, and C when selected from among A, B, and C,” the phrase can refer to any and all combinations 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 in this document, the terms “use” and “used” can be considered equivalent to the terms “utilize” and “utilized”, respectively. As used in this document, the terms “substantially,” “approximately,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent deviations in measured or computed values that would be recognized by those of ordinary skill in the art.

[0054] It will be understood that, although the terms“first,”“second,”“third,” etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0055] Spatially relative terms such as“beneath,”“below,”“lower,”“above,” and“upper” are used herein for ease of description to describe one element or feature’s relationship to another element(s) or feature(s) as depicted in the figures. 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 a device in the figures is turned over, elements described as“below” or“beneath” other elements or features would then be oriented“above” or“over” the other elements or features. Thus, the term“below” can encompass both an orientation of above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0056] The terminology used in the present disclosure is for the purpose of describing embodiments of the present disclosure and is not intended to be limiting of the present disclosure. As used in the present disclosure, the singular forms“a,”“an,” and“the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms“comprises,”“comprising,”“includes,” and / or“including,” as used herein, specify the presence of 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] Further, any numerical range recited in this document is intended to include all sub-ranges of the same whole number precision subsumed in the recited range. For example, a range of "1.0 to 10.0" is intended to include all sub-ranges between (and including) the recited minimum and maximum values, e.g., 2.4 to 7.6, etc. Any maximum numerical limitation recited in this specification is intended to include all lower numerical limitations subsumed therein and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations subsumed therein. Accordingly, it is the applicant's intent that every aspect of the present application recited in this Application, including but not limited to the claims, be interpreted in the broadest possible manner consistent with the terminology thereof.

[0058] Reference to two comparative elements, features, etc. being "the same" can mean that they are "substantially the same". Thus, the phrase "substantially the same" can include instances where there is a deviation considered to be low in the art (e.g., a deviation of 5% or less). Further, when a certain parameter is said to be uniform in a given region, this can mean that it is uniform in terms of average value.

[0059] Throughout the specification, each element can be singular or plural, unless otherwise stated.

[0060] When any element is referred to as being "on" or "under" or "above" or "below" another element, it can mean that the element is in contact with the other element, or it can also mean that another element can be interposed between the element and the other element.

[0061] Further, it will be understood that when an element is referred to as being "coupled", "connected", or "linked" to another element, it can be directly coupled, connected, or linked to the other element or one or more intervening elements can exist between the element and the other element, the element can be coupled, connected, or linked to the other element through these intervening elements. Further, when a portion is referred to as being "electrically connected" to another portion, the portion can be directly electrically connected to the other portion, or one or more intervening components can exist between the portion and the other portion, such that the portion and the other portion 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 items listed. When stating "C to D", it means above C and below D, unless otherwise stated.

[0063] The terms used in the specification are used to describe embodiments of the present disclosure and are not intended to limit the present disclosure.

[0064] Figure 1 is a schematic perspective view illustrating a configuration of an energy storage system according to some embodiments of the present disclosure. Figure 2 is a schematic front view illustrating a configuration of an energy storage system according to some embodiments of the present disclosure. Figure 3 is a schematic plan view illustrating a configuration of an energy storage system according to some embodiments of the present disclosure. Figure 4 is a schematic perspective view illustrating a configuration of a blocking member according to some embodiments of the present disclosure.

[0065] Referring to Figures 1 to 4 , an energy storage system according to some embodiments includes a container 100, accommodation portions 200, a partition wall 300, ventilation holes 400, and a blocking member 500.

[0066] The container 100 forms an approximate appearance of the energy storage system. The container 100 can be a closed structure of various suitable types (e.g., a separate building, a room in a building, and a container) having a hollow interior. Except for Figure 1 the rectangular parallelepiped shape as shown in FIG. 1, the shape design of the container 100 can be changed to various shapes (e.g., other polyhedral shapes or a cylindrical shape).

[0067] The accommodation portions 200 can be empty spaces formed within the container 100. A plurality of accommodation portions 200 can be provided. Although Figures 1 to 3 an example in which three accommodation portions 200 are formed is shown, the number of accommodation portions 200 is not limited thereto, and the design thereof can be changed to various numbers (e.g., two or four).

[0068] The accommodation portions 200 can be disposed at different positions within the container 100. For example, as shown in Figures 1 to 3 , a plurality of accommodation portions 200 can be disposed in a row within the container 100. For example, the plurality of accommodation portions 200 can be disposed in a grid form within the container 100, or can be vertically stacked within the container 100. The shapes and volumes of the accommodation portions 200 can be the same as or different from each other.

[0069] Each of the accommodation portions 200 can accommodate any one of a battery rack 10 and an air conditioner 20 therein.

[0070] The battery rack 10 can include a rack frame 11 having a plurality of storage spaces, and a plurality of battery modules 12 disposed within the storage spaces of the rack frame 11 and electrically connected to each other. The battery module 12 can include a plurality of battery cells capable of storing or releasing electric power.

[0071] The air conditioner 20 can be a blower or a heating, ventilation, and air conditioning (HVAC) device that can adjust the flow rate, temperature, and humidity of ambient air.

[0072] The battery rack 10 and the air conditioner 20 can each be accommodated in one of an adjacent pair of 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 arranged in the center portion, and the battery rack 10 can be accommodated in each of the accommodation portions 200 arranged on the sides. However, the arrangement state of the battery rack 10 and the air conditioner 20 is not limited to Figure 1 those depicted in FIG. 1, and in embodiments in which at least one battery rack 10 and at least one air conditioner 20 are accommodated in a plurality of accommodation portions 200, the design can be changed differently.

[0073] The partition wall 300 is disposed between an adjacent pair of accommodation portions 200 and separates the adjacent pair of 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 disposed to be parallel to a boundary surface between the adjacent pair of accommodation portions 200. The partition wall 300 can be disposed such that each of its surfaces faces one of the adjacent pair of accommodation portions 200. The area of the partition wall 300 can be formed to be greater than the area of the boundary surface between the adjacent pair of accommodation portions 200. The partition wall 300 can be made of a non-combustible and fire-resistant material (e.g., concrete, ceramic, or steel) to prevent or substantially reduce damage caused by a flame or the like and to contain a fire in the event of a fire. A plurality of partition walls 300 can be provided. Each of the partition walls 300 can be individually disposed between the adjacent pair of accommodation portions 200.

[0074] The ventilation hole 400 (see, for example, Figure 4 ) can be formed through the partition wall 300, and each of the sides of the ventilation hole 400 is connected with one of the adjacent pair of accommodation portions 200. That is, the ventilation hole 400 can serve as a path through which air can be transferred from one of the adjacent pair of accommodation portions 200 to the other accommodation portion 200. The design can be changed differently within a range in which the area of the ventilation hole 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 disposed to be spaced apart from each other in the partition wall 300. The plurality of ventilation holes 400 can be vertically disposed in a row, or can also be disposed in two or more rows. Hereinafter, as Figure 4 shown in FIG. 2, an example in which the ventilation hole 400 is formed through all areas of the partition wall 300 except for both ends will be described.

[0075] The blocking member 500 selectively opens or closes the vent hole 400 using its driving force. Accordingly, the blocking member 500 can allow internal air of one accommodation portion 200 to be transferred to an adjacent accommodation portion 200 through the vent hole 400 under normal circumstances, and can block a flame or smoke generated in one accommodation portion 200 from being transmitted to an adjacent accommodation portion 200 through the vent hole 400 when a fire occurs. A plurality of blocking members 500 can be provided. The plurality of blocking members 500 can be individually installed with respect to the vent hole 400 formed in each of the partition walls 300.

[0076] Figure 5 is a view illustrating a state in which a blocking member closes a vent hole according to some embodiments of the disclosure. Figure 4

[0077] Referring to Figure 4 and Figure 5 The blocking member 500 according to some embodiments can include a damper member 511 and an actuator 513.

[0078] The damper member 511 can be rotatably connected to the partition wall 300 and can open or close the vent hole 400 according to a rotation direction. For example, the damper member 511 can be rotated in a first direction to close the vent hole 400 and can be rotated in a direction opposite to the first direction to open the vent hole 400. Here, the first direction can be a clockwise direction or a counterclockwise direction with respect to a rotation axis of the damper member 511.

[0079] The damper member 511 according to some embodiments can include a plurality of dampers 512.

[0080] The damper 512 can be formed to have a flat plate shape. A longitudinal direction (or a length direction) of the damper 512 can be parallel to a bottom surface of the container 100. Both sides of the damper 512 in the longitudinal direction can be rotatably connected to the partition wall 300 through a rotation axis. Since a transverse direction (or a width direction) of the damper 512 is perpendicular to the vent hole 400, the damper 512 can open the vent hole 400. In this state, when the damper 512 is rotated in a first direction (for example, a clockwise direction) in Figure 4 and Figure 5 the damper 512 in the view, an inner surface of the damper 512 can be disposed to face the vent hole 400, and the vent hole 400 can be closed.

[0081] ​A plurality of dampers 512 can be provided. The plurality of dampers 512 can be disposed to be vertically spaced apart from each other at intervals. The sum of the areas of the plurality of dampers 512 can be greater than the area of the vent 400. In this case, when an adjacent pair of dampers 512 closes the vent 400, the adjacent pair of dampers 512 can be disposed such that at least a portion of their areas overlap each other. Accordingly, when the plurality of dampers 512 is sufficiently rotated in the first direction, the dampers 512 can close the vent 400 without any gap.

[0082] A fireproof coating can be coated on the surface of the damper 512 to prevent or substantially reduce thermal damage in the event of a fire.

[0083] The actuator 513 is connected to the damper member 511 and can generate a rotational force to control the rotational direction of the damper member 511. The actuator 513 according to some embodiments can include a motor that receives power from the outside to generate a rotational force, and a power transmission part (e.g., a gear or a pulley) connected to the motor and transmitting the rotational force of the motor to the damper member 511.

[0084] The motor can be formed in a number corresponding to the number of the plurality of dampers 512, or can be formed individually (e.g., a single motor can be provided). The motor can be disposed inside the accommodation portion 200, or can be disposed outside the container 100.

[0085] The power transmission part can be individually connected to the rotational shafts of the plurality of dampers 512. The power transmission part can receive a rotational force from the motor, thereby simultaneously rotating the plurality of dampers 512 at the same angular velocity.

[0086] The energy storage system according to some embodiments can further include a fire extinguishing member 600 (e.g., see Figure 1 ).

[0087] When a fire has occurred in the accommodation portion 200, the fire extinguishing member 600 sprays a fire extinguishing liquid into the accommodation portion 200. That is, the fire extinguishing member 600 can function as a member that extinguishes a fire generated in the accommodation portion 200 when a fire occurs.

[0088] The fire extinguishing member 600 according to some embodiments can include a storage portion 610 that stores a fire extinguishing liquid, and a spray line 620 that extends from the storage portion 610 into the accommodation portion 200.

[0089] The storage portion 610 can be various suitable types of storage containers capable of storing a fire extinguishing liquid.

[0090] The injection line 620 can be a pipe having one side connected to the storage portion 610 and the other side passing through the container 100 and disposed within the accommodation portion 200. In the injection line 620, a pump supplying the fire extinguishing liquid stored in the storage portion 610 to the injection line 620 can be installed, and a nozzle injecting the fire extinguishing liquid flowing along the injection line 620 into the accommodation portion 200 can be installed. A plurality of injection lines 620 can be provided. The plurality of injection lines 620 can each be individually disposed within one of the accommodation portions 200.

[0091] Figure 6 is a schematic block diagram illustrating a configuration of an energy storage system according to some embodiments of the present disclosure.

[0092] Referring to Figures 1 to 3 and Figure 6 , the energy storage system according to some embodiments can further include a detection member 700 and a controller 800.

[0093] The detection member 700 collects environmental data within the accommodation portion 200. Here, the environmental data can include information on an internal temperature of the accommodation portion 200 (i.e., a temperature within the accommodation portion 200) and information on the presence of smoke.

[0094] The detection member 700 according to some embodiments can include a temperature sensor 710 and a smoke sensor 720.

[0095] The temperature sensor 710 detects an internal temperature of the accommodation portion 200. The temperature sensor 710 according to some embodiments can be a thermal sensor or an infrared sensor, etc. capable of detecting a temperature. A plurality of temperature sensors 710 can be provided. The plurality of temperature sensors 710 can be individually installed within each of the accommodation portions 200. The plurality of temperature sensors 710 can be installed in each of the accommodation portions 200. As an example, as shown in Figures 1 to 3 , two temperature sensors 710 can be installed in each of the accommodation portions 200.

[0096] The smoke sensor 720 detects smoke generated within the accommodation portion 200. The smoke sensor 720 according to some embodiments can be various suitable types of smoke detectors such as an ionization smoke sensor and a photoelectric smoke sensor capable of detecting smoke generated by combustion. A plurality of smoke sensors 720 can be provided. The plurality of smoke sensors 720 can be individually installed within each of the accommodation portions 200. The plurality of smoke sensors 720 can be installed in each of the accommodation portions 200. As an example, as shown in Figures 1 to 3 , two smoke sensors 720 can be installed in each of the accommodation portions 200.

[0097] The controller 800 controls the overall operation of the blocking member 500, the fire extinguishing member 600, and the air conditioner 20. For example, the controller 800 can determine whether a fire has occurred in the accommodation portion 200 based on data detected by the detection member 700, and based on the determined information, the controller 800 can control the operation of the blocking member 500, the fire extinguishing member 600, and the air conditioner 20.

[0098] In addition, the controller 800 can determine whether a fire has occurred in the accommodation portion 200 based on environmental data collected by the detection member 700, and can generate a warning signal or an emergency signal based on the determined information. The warning signal and the emergency signal can be signals that a user can distinguish from each other. The warning signal and the emergency signal can include a signal such as an alarm sound that can be audibly recognized by a user or a signal such as an image, lighting, or a combination thereof that can be visually recognized by a user.

[0099] The controller 800 can include an electronic control device that monitors data detected by the detection member 700 in real time and controls the operation 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 can be implemented as an integrated circuit (IC), a microcontroller (μC), a microprocessor, an application specific integrated circuit (ASIC), or a combination thereof, which can control a plurality of 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 can include a visually recognizable lighting device, a display, or an acoustic device configured to generate an aurally recognizable signal.

[0100] Hereinafter, the operation of the energy storage system according to some embodiments of the disclosure will be described.

[0101] Figure 7 is a schematic flowchart illustrating an operation process of the energy storage system according to some embodiments of the disclosure.

[0102] Referring to Figures 1 to 7 , the detection member 700 collects environmental data within the accommodation portion 200 (operation S10).

[0103] The controller 800 determines whether a fire has occurred based on data detected by the detection member 700 (operation S20).

[0104] Figures 8 to 10 is a schematic flowchart illustrating a process in which the controller determines whether a fire has occurred according to some embodiments of the disclosure.

[0105] Referring to Figure 8 , in operation S20, the controller 800 can determine whether a fire has occurred based on temperature data detected by the temperature sensor 710 (operation S210).

[0106] For example, the controller 800 determines whether the number of temperature sensors 710 detecting a temperature higher than or equal to the set temperature in any one of the accommodation portions 200 is one or more and less than n (operation S211). Here, n can be any one of natural numbers of two or more.

[0107] When the number of temperature sensors 710 detecting a temperature higher than or equal to the set temperature is one or more and less than n in operation S211, the controller 800 generates a warning signal (operation S212).

[0108] The controller 800 determines whether the number of temperature sensors 710 detecting a temperature higher than or equal to the set temperature in any one of the accommodation portions 200 is n or more (operation S213). As Figure 1 As shown in the above description, when two temperature sensors 710 are installed in each of the accommodation portions 200, n can be two.

[0109] When the number of temperature sensors 710 detecting a temperature higher than or equal to the set temperature is n or more in operation S213, the controller 800 generates a fire operation signal (operation S214). The fire operation signal can be an electrical signal for operating the blocking member 500, the fire extinguishing member 600, and the air conditioner 20.

[0110] Referring to Figure 9 In operation S20, the controller 800 can determine whether a fire has occurred based on smoke data detected by the smoke sensor 720 (operation S220).

[0111] For example, the controller 800 determines whether the number of smoke sensors 720 detecting smoke in any one of the accommodation portions 200 is one or more and less than m (operation S221). Here, m can be any one of natural numbers of two or more.

[0112] When the number of smoke sensors 720 detecting smoke is one or more and less than m in operation S221, the controller 800 generates a warning signal (operation S222).

[0113] The controller 800 determines whether the number of smoke sensors 720 detecting smoke in any one of the accommodation portions 200 is m or more (operation S223). As Figure 1 As shown in the above description, when two smoke sensors 720 are installed in each of the accommodation portions 200, m can be two.

[0114] When the number of smoke sensors 720 detecting smoke is m or more in operation S223, the controller 800 generates a fire operation signal (operation S224).

[0115] Referring to Figure 10 In operation S20, based on a combination of temperature data detected by the temperature sensors 710 and smoke data detected by the smoke sensors 720 in any one of the accommodation portions 200, the controller 800 can determine whether a fire has occurred (operation S230).

[0116] That is, in operation S230, when the temperature detected by any one of the temperature sensors 710 is higher than or equal to a 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 a set temperature or when smoke is detected by any one of the smoke sensors 720, the controller 800 can generate only a warning signal.

[0117] For example, as shown in FIG. 2, the controller 800 determines whether the temperature detected by any one of the temperature sensors 710 among the plurality of temperature sensors 710 installed in any one of the accommodation portions 200 is higher than or equal to a set temperature (operation S231). Figure 10

[0118] When the temperature detected by all of the temperature sensors 710 is lower than the set temperature in operation S231, the controller 800 determines whether any one of the plurality of 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 can take no action, and operation S230 can be in an end state (END).

[0121] When the temperature detected by any one of the temperature sensors 710 is higher than or equal to a set temperature in operation S231, the controller 800 determines whether any one of the smoke sensors 720 has detected smoke (operation S234).

[0122] When all of the smoke sensors 720 have not 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 can perform all of operations S210, S220, and S230, or can 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 illustrating an operation process of an energy storage system according to some embodiments of the present disclosure.

[0126] Referring to Figure 7 and Figure 11 When the controller 800 determines that a fire has not occurred in operation S20, the damper 512 maintains a state in which a width direction thereof is perpendicular to the vent 400, and the vent 400 is maintained in an open state.

[0127] When the vent 400 is maintained in the open state, air A flowing in one accommodation portion 200 can receive a flow force from the air conditioner 20 to be transferred into an adjacent accommodation portion 200 through the vent 400, and can circulate through the plurality of accommodation portions 200.

[0128] Referring to Figure 7 and Figure 12 When the controller 800 determines that a fire has occurred in operation S20, the controller 800 transmits a fire operation signal to the air conditioner 20 to stop an operation of the air conditioner 20 (operation S30).

[0129] The controller 800 can transmit the fire operation signal to the actuator 513 to close the vent 400 (operation S40).

[0130] For example, when the fire operation signal is received from the controller 800, the actuator 513 can 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 vent 400.

[0132] When the vent 400 is completely closed, a flame C and smoke B generated in the accommodation portion 200 can not flow into the vent 400, and fire propagation through the vent 400 can be prevented.

[0133] The controller 800 can transmit the fire operation signal to the fire extinguishing member 600, and the fire extinguishing member 600 can spray a fire extinguishing liquid into the accommodation portion 200 to extinguish a fire in the accommodation portion 200 (operation S50). In this case, the controller 800 can control an operation of a pump so that the fire extinguishing liquid is supplied only to the spray line 620 disposed in the accommodation portion 200 in which it is determined that a fire has occurred among the plurality of spray lines 620.

[0134] When the controller 800 determines that a fire has occurred, the controller 800 can generate an emergency signal (operation S60).

[0135] Hereinafter, a configuration of an energy storage system according to some other embodiments of the disclosure will be described.

[0136] Figure 13 is a schematic perspective view illustrating a configuration of an energy storage system according to some embodiments of the disclosure. Figure 14 is a schematic front view illustrating a configuration of an energy storage system according to some embodiments of the disclosure. Figure 15 is a schematic plan view illustrating a configuration of an energy storage system according to some embodiments of the disclosure. Figure 16 is a schematic perspective view illustrating a configuration of a blocking member according to some embodiments of the disclosure. Figure 17 is a perspective view illustrating a state in which the blocking member in Figure 16 closes a vent according to some embodiments of the disclosure.

[0137] Referring to Figures 13 to 17 , an energy storage system according to some embodiments includes a container 100, an accommodation portion 200, a partition wall 300, a vent 400, a blocking member 500, a fire extinguishing member 600, a detection member 700, and a controller 800.

[0138] An energy storage system according to some embodiments of the disclosure can be configured to differ from the previously described energy storage system according to some embodiments of the disclosure only in a detailed configuration of the blocking member 500.

[0139] Accordingly, in describing an energy storage system according to some embodiments of the 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 disclosure will be described.

[0140] The previously mentioned description of the energy storage system according to some embodiments of the disclosure can be applied to the remaining configuration of the energy storage system according to some embodiments of the disclosure without any change.

[0141] The blocking member 500 according to some embodiments can include a damper member 531, an adjustment member 533, and an actuator 536.

[0142] The damper member 531 can be rotatably connected to the partition wall 300 and can open or close the vent 400 according to a rotation direction. For example, the damper member 531 can be rotated in a first direction to close the vent 400 and can be rotated in a direction opposite to the first direction to open the vent 400. Here, the first direction can be a clockwise direction or a counterclockwise direction with respect to a rotation axis of the damper member 531.

[0143] The damper member 531 according to some embodiments can include a plurality of dampers 532.

[0144] The dampers 532 can be formed to have a flat plate shape. A longitudinal direction (or a length direction) of the dampers 532 can be parallel to the bottom surface of the container 100. Both sides of the dampers 532 in the longitudinal direction can be rotatably connected to the partition wall 300 through a rotating shaft. Because a transverse direction (or a width direction) of the dampers 532 is perpendicular to the ventilation hole 400, the dampers 532 can open the ventilation hole 400. In this state, when the dampers 532 rotate in a first direction (for example, a clockwise direction in FIG. 4), an inner surface of the dampers 532 can be disposed to face the ventilation hole 400, and the ventilation hole 400 can be closed. Figure 16 and Figure 17 In this state, when the dampers 532 rotate in a first direction (for example, a clockwise direction in FIG. 4), an inner surface of the dampers 532 can be disposed to face the ventilation hole 400, and the ventilation hole 400 can be closed.

[0145] A plurality of dampers 532 can be provided. The plurality of dampers 532 can be disposed to be vertically spaced apart from each other at intervals. The sum of the areas of the plurality of dampers 532 can 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 can be disposed such that at least a part of their areas overlap each other. Accordingly, when the plurality of dampers 532 is sufficiently rotated in the first direction, the dampers 532 can close the ventilation hole 400 without any gap.

[0146] A fireproof coating can be coated on the surface of the dampers 532 to prevent or substantially reduce thermal damage when a fire occurs.

[0147] The adjustment 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 change in temperature. That is, when there is no separate temperature change, the adjustment member 533 can restrict the damper member 531 from rotating in the first direction, so that the ventilation hole 400 is maintained in an open state. In addition, when heated to a set temperature or more by a flame or the like, the adjustment member 533 can allow the damper member 531 to rotate in the first direction, so that the ventilation hole 400 is closed.

[0148] The adjustment member 533 according to some embodiments can 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 can serve as a component that rotates the damper member 531 in the first direction using the weight.

[0150] The rod 534 according to some embodiments can be formed to have a shape of a bar. The rod 534 can be integrally coupled to the edge surface of the damper 532 by welding or bolting, etc. A plurality of dampers 532 can be arranged in the longitudinal direction of the rod 534. The dampers 532 can be coupled to different positions of the rod 534 in the longitudinal direction. Accordingly, the rod 534 can synchronize the operations (i.e., rotational speed, rotational direction, or rotational angle, etc.) of the plurality of dampers 532. A pair of rods 534 can be provided. The pair of rods 534 can be spaced apart from each other in the longitudinal direction of the dampers 532, and can each be coupled to one of the two sides of the dampers 532 in the longitudinal direction.

[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 can serve as a means to offset the rotational force applied to the damper member 531 in the first direction by the rod 534 using its own tension. Accordingly, when a fire has not yet occurred, the damper member 531 can maintain the ventilation hole 400 in an open state.

[0152] The rope 535 can be cut by the operation of the actuator 536, which will be described below. Accordingly, when a fire occurs, the rope 535 can release the rotational force acting on the damper member 531 in a direction opposite to the first direction, and can urge the damper member 531 to rotate in the first direction. The design can be variously changed to change the set temperature within the temperature range in which the rope 535 can be cut when a fire occurs in the accommodation portion 200.

[0153] The rope 535 can be cut when heated above the set temperature due to contact with a flame or smoke. Accordingly, even when the actuator 536 is damaged or malfunctions, the rope 535 can be cut, thereby further improving the reliability of the fireproof performance. Here, the set temperature at which the rope 535 is cut can be different from the set temperature detected by the temperature sensor 710.

[0154] The rope 535 can be provided above the accommodation portion 200 (where relatively high-temperature air and smoke gather due to convection when a fire occurs). In this case, the rope 535 can be supported on the top surface of the container 100 by a clamp or the like. Accordingly, even in the case where the rope 535 has difficulty in directly contacting a flame due to the volume of the accommodation portion 200 itself, the rope 535 can 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 disposed in one of the adjacent accommodation portions 200, respectively. Accordingly, the rope 535 can be prevented from being cut only by a fire occurring in one of the adjacent pair of accommodation portions 200.

[0156] The ropes 535 provided in the different blocking members 500 can be connected to each other. For example, as shown in FIG. 6, three accommodation portions 200 can be arranged in a row, and thus, a pair of blocking members 500 individually opening or closing the ventilation holes 400 formed in the different partition walls 300 can be individually installed on both sides of the accommodation portion 200 disposed at the center portion. Both ends of the rope 535 provided in each of the blocking members 500 can be disposed in the adjacent accommodation portions 200, and thus, one end of the rope 535 provided in the different blocking members 500 can be simultaneously disposed in the accommodation portion 200 disposed at the center portion and connected to each other. Accordingly, when a fire occurs in one of the plurality of accommodation portions 200, the plurality of blocking members 500 can simultaneously close the ventilation holes 400 formed in the different partition walls 300. Figure 15

[0157] The actuator 536 generates a driving force to cut the rope 535. The actuator 536 according to some embodiments can be an electric cutter connected to the rope 535 and capable of cutting the rope 535 by receiving electric 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 disposed to be spaced apart from each other in the extension 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 operation as the operation described above in some embodiments of the present disclosure, 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 in a cut state, 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 the width direction thereof is perpendicular to the ventilation hole 400, and the ventilation hole 400 can be maintained in an open state. ​

[0163] When the vent hole 400 is maintained in the open state, the air A flowing in one of the accommodation portions 200 can receive a flow force from the air conditioner 20 to be transferred into the adjacent accommodation portion 200 through the vent hole 400, and can circulate through the plurality of accommodation portions 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 can 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 vent hole 400.

[0166] For example, the actuator 536 cuts the rope 535 when receiving the fire operation signal from the controller 800.

[0167] When the rope 535 is cut, the tension applied by the rope 535 to the damper 532 is released, and the damper 532 rotates in the first direction by the weight of the rod 534.

[0168] The damper 532 rotates in the first direction and closes the vent hole 400.

[0169] When the vent hole 400 is completely closed, the flame C and the smoke B generated in the accommodation portion 200 can not flow into the vent hole 400, and the fire spread through the vent hole 400 can be prevented.

[0170] When the rope 535 is not properly cut due to damage or failure of the actuator 536, the rope 535 can be cut by being heated above the set temperature by contact with the flame C or the smoke B generated in the accommodation portion 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 the fire extinguishing liquid into the accommodation portion 200 to extinguish the fire in the accommodation portion 200. In this case, the controller 800 can control the operation of the pump so that the fire extinguishing liquid is supplied only to the spray line 620 disposed in the accommodation portion 200 in which it is determined that a fire has occurred among the plurality of spray lines 620.

[0172] Hereinafter, a 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 illustrating a configuration of an energy storage system according to some embodiments of the present disclosure. Figure 23is a schematic front view illustrating a configuration of an energy storage system according to some embodiments of the disclosure. Figure 24 is a schematic plan view illustrating a configuration of an energy storage system according to some embodiments of the disclosure.

[0174] Referring to Figures 22 to 24 , the energy storage system according to some embodiments includes a container 100, a housing portion 200, a partition wall 300, a vent 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 disclosure can be configured to be different from the previously described energy storage system according to some embodiments of the disclosure only in the detailed configuration of the blocking member 500.

[0176] Accordingly, in describing the energy storage system according to some embodiments of the 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 disclosure will be described.

[0177] The previously mentioned description of the energy storage system according to some embodiments of the disclosure can be applied to the configuration of the energy storage system according to some embodiments of the disclosure without any change.

[0178] The blocking member 500 according to some embodiments can 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 installed to be movable between a first position and a second position.

[0180] Figure 25 is a schematic perspective view illustrating a state in which the movable partition wall is disposed in the first position according to some embodiments of the disclosure. Figure 26 is a schematic perspective view illustrating a state in which the movable partition wall is disposed in the second position according to some embodiments of the disclosure.

[0181] Referring to Figures 22 to 26 , the movable partition wall 541 according to some embodiments can be formed in a substantially flat plate shape and can be disposed to be parallel to the partition wall 300. An inner surface of the movable partition wall 541 and an inner surface of the partition wall 300 can be disposed to face each other. A fireproof paint can be coated on an 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 smaller 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 completely lowered to be in contact with the bottom surface of the container 100. Also, 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 to a certain level from the second position. When no separate external force is applied, the movable partition wall 541 can be located at the second position by the weight thereof.

[0183] The movable hole 542 is formed through the movable partition wall 541 and selectively communicates 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 disposed 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 disposed to be misaligned with the ventilation hole 400 and can block air, flame, 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 disposed 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 serve as a member that positions the movable partition wall 541 at the first position by using the tension thereof to offset the weight of the movable partition wall 541. Accordingly, when no fire occurs, the ventilation hole 400 can be maintained in an open state.

[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 the weight thereof to close the ventilation hole 400.

[0187] Also, the rope 543 can be cut when heated to a set temperature or more by a flame or the like. Accordingly, even when the actuator 545 is damaged or malfunctions, the rope 543 can be cut, thereby further improving the reliability of the fireproof performance (e.g., increasing). 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] Rope 543 can be positioned above the containment portion 200 (where relatively hot air and smoke accumulate due to convection during a fire). In this case, rope 543 can be supported on the top surface of container 100 by clamps or the like. Accordingly, even if rope 543 is difficult to directly contact the flame due to the volume of the containment portion 200 itself, rope 543 can be quickly cut.

[0189] Rope 543 can pass through the upper end of the movable partition wall 541, and both ends of rope 543 can be respectively located in one of the adjacent receiving portions 200. Accordingly, it is possible to prevent rope 543 from being cut by a fire occurring in only one of the adjacent pair of receiving portions 200.

[0190] The ropes 543 provided in the different blocking members 500 can be connected to each other. For example, as Figure 23 As shown, the three receiving portions 200 can be arranged in a row, and thus, a pair of blocking members 500 that individually open or close the ventilation openings 400 formed in the different partition walls 300 can be individually installed on both sides of the receiving portion 200 located in the central portion. The two ends of the rope 543 provided in each blocking member 500 can be located in adjacent receiving portions 200, and thus, one end of the rope 543 provided in different blocking members 500 can be simultaneously located in the receiving portion 200 located in the central portion and connected to each other. Accordingly, when a fire occurs in one of the multiple receiving portions 200, the multiple blocking members 500 can simultaneously close the ventilation openings 400 formed in the different partition walls 300.

[0191] Actuator 545 generates a driving force to cut rope 543. According to some embodiments, actuator 545 may be an electric cutter connected to rope 543 and capable of cutting rope 543 by receiving power from an external source. Multiple actuators 545 may be provided. Multiple actuators 545 may be arranged spaced apart from each other in the direction of extension of rope 543.

[0192] According to some embodiments, the blocking member 500 may further include guide rails 544 for guiding 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 provided on both sides of each of the partition wall 300 and the movable partition wall 541.

[0193] Figure 27 This is a schematic enlarged view illustrating the configuration of guide rails according to some embodiments of the present disclosure. Figure 28 This is a schematic cross-sectional view illustrating the configuration of a guide rail according to some embodiments of the present disclosure.

[0194] refer toFigures 22 to 28 The guide rail 544 according to some embodiments can 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 can be formed to have a flat cylindrical shape. The upper end and the lower end of the guide body 544a can be fixed to the top surface and the bottom surface of the container 100, respectively. The guide body 544a can be disposed perpendicular to the partition wall 300 and the movable partition wall 541. The inner surface of the guide body 544a can be disposed to face the side surface of each of the partition wall 300 and the movable partition wall 541.

[0196] The first extension portion 544b can extend from one end of the guide body 544a and can be disposed to face the outer surface of the partition wall 300. The first extension portion 544b can be fixed to the outer surface of the partition wall 300 by welding or bolting, etc.

[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 can 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 can 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 an 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 the operations described above in some embodiments of the present disclosure and can determine whether a fire has occurred.

[0201] Referring to Figure 22 and Figure 29 When the controller 800 determines that a fire has not occurred, the rope 543 remains in a cut-off state.

[0202] Since the tension of the rope 543 offsets the weight of the movable partition wall 541, the movable partition wall 541 remains in a state of being located at the first position.

[0203] Accordingly, the movable hole 542 can be disposed to face the ventilation hole 400, and the ventilation hole 400 can be maintained in an open state.

[0204] When the vent hole 400 is maintained in the open state, the air A flowing in one of the accommodation portions 200 can receive a flow force from the air conditioner 20 to be transferred into the adjacent accommodation portion 200 through the vent hole 400, and can circulate through the plurality of accommodation portions 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 the fire operation signal to the actuator 545 to close the vent hole 400.

[0207] For example, the actuator 545 cuts the rope 543 when receiving the fire operation signal from the controller 800.

[0208] When the rope 543 is cut, the tension applied by the rope 543 to the movable partition wall 541 is released, and the movable partition wall 541 moves to the second position by the weight.

[0209] When the movable partition wall 541 moves to the second position, the movable hole 542 is disposed to be misaligned with the vent hole 400, and the vent hole 400 is closed. In other words, the vent hole 400 is blocked by the movable partition wall 541.

[0210] When the vent hole 400 is completely closed, the flame C and the smoke B generated in the accommodation portion 200 can not flow into the vent hole 400, and the fire propagation through the vent hole 400 can be prevented.

[0211] When the rope 543 is not properly cut due to damage or failure of the actuator 545, the rope 543 can be cut by being heated above the set temperature by contact with the flame C or the smoke B generated in the accommodation portion 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 the fire extinguishing liquid into the accommodation portion 200 to extinguish the fire in the accommodation portion 200. In this case, the controller 800 can control the operation of the pump so that the fire extinguishing liquid is supplied only to the spray line 620 disposed in the accommodation portion 200 in which it is determined that the fire has occurred among the plurality of spray lines 620.

[0213] According to the present disclosure, in normal circumstances, the inside air of any one accommodation portion can be transferred to an adjacent accommodation portion through the ventilation hole, thereby uniformly maintaining the internal environment of the plurality of accommodation portions.

[0214] According to the present disclosure, in the event of a fire, the flame or smoke generated in any one accommodation portion is blocked from being transmitted to an adjacent accommodation portion through the ventilation hole, 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 hole by controlling the operation of the blocking member based on the data detected by the detection member, thereby ensuring accurate fireproof performance.

[0216] According to the present disclosure, even when the actuator is damaged or malfunctions, the rope can be cut by contact with the flame or smoke, thereby further improving the reliability of the fireproof performance.

[0217] However, the effects obtainable by the present disclosure are not limited to the above-mentioned effects, and other technical effects not mentioned will be clearly understood by those skilled in the art based on the description of the present disclosure.

[0218] While the present disclosure has been described with reference to the embodiments illustrated in the drawings, these embodiments are merely illustrative and it will be understood by those skilled in the art that various modifications can be derived from these embodiments and other embodiments equivalent thereto.
