Description

Technical Field

[0001] This application relates to the field of electrochemical energy storage technology, and in particular to an energy storage device. Background Technology

[0002] In related technologies, energy storage devices such as energy storage valve towers are usually arranged in an array, and in order to control site costs, the spacing between energy storage devices is set relatively small.

[0003] However, because energy storage devices contain batteries, they are at risk of thermal runaway during operation. In such cases, the close spacing between energy storage devices means that if a fire occurs in one device due to thermal runaway, it can easily spread to other devices. Utility Model Content

[0004] The main objective of this application is to provide an energy storage device designed to reduce the possibility of fire spread in the event of thermal runaway and subsequent fire.

[0005] To achieve the above objectives, the energy storage device proposed in this application includes:

[0006] The device body includes a main body and an energy storage module, with the energy storage module located in the main body;

[0007] A barrier mechanism, disposed on the body, includes a drive module and a partition. The partition is connected to the drive module and has a retracted state and an extended state. The drive module is configured to drive the partition to move and extend to cover at least a portion of the side of the body.

[0008] The control module is located in the body and includes a sensing module, a controller, and a manual switch. The sensing module is located in the body and is electrically connected to the controller. The sensing module includes at least one of a temperature sensor and a smoke sensor. The controller and the manual switch are both electrically connected to the drive module.

[0009] The energy storage device of this application incorporates a barrier mechanism on its body. In the event of thermal runaway and subsequent fire, a partition within the barrier mechanism can be driven by a drive module to expand and cover at least a portion of the body's sides. This partition effectively isolates the fire-affected energy storage device from the unaffected device, preventing further spread of the fire to the unaffected device.

[0010] Furthermore, the energy storage device in this solution also includes a control module. This control module comprises a sensing module, a controller, and a manual switch. The sensing module, including at least one of a temperature sensor and a smoke sensor, can detect the occurrence of thermal runaway, triggering the controller to promptly activate the drive module, which moves and deploys the partition to prevent the spread of fire. The manual switch allows for manual activation of the drive module in emergencies to prevent the partition from spreading. Therefore, the inclusion of a control module facilitates the timely activation of the fire-prevention mechanism, thereby further reducing the possibility of fire spread.

[0011] Optionally, the number of temperature sensors is multiple, including a top temperature sensor and a bottom temperature sensor;

[0012] The top temperature sensor is located at the top of the unit, and the bottom temperature sensor is located at the bottom of the unit.

[0013] Therefore, the temperature of the device body can be detected in different zones, improving the accuracy of the overall temperature detection of the device body.

[0014] Optionally, the multiple temperature sensors also include a central temperature sensor located between the top and bottom of the body.

[0015] This allows for more precise temperature detection in different zones of the device body, improving the accuracy of overall temperature detection and facilitating further improvements.

[0016] Optionally, there are multiple top temperature sensors, with at least some of them arranged around the circumference of the body;

[0017] And / or, the number of central temperature sensors is multiple, and at least some of the central temperature sensors are arranged around the circumference of the body;

[0018] And / or, the number of bottom temperature sensors is multiple, with at least some of the bottom temperature sensors arranged circumferentially around the body.

[0019] Therefore, the temperature can be further measured in circumferential sections at the top, middle, and bottom of the device to improve the accuracy of the overall temperature measurement of the device.

[0020] Optionally, the smoke sensor is located at the top of the device.

[0021] Therefore, the adaptability of upward-flowing smoke airflow can be detected, making it convenient to achieve timely and accurate smoke detection.

[0022] Optionally, there may be multiple smoke sensors, with at least some of the smoke sensors arranged circumferentially around the body.

[0023] Therefore, smoke can be generated in sections along the circumference at the top of the device to further improve the accuracy of detecting whether the entire device generates smoke.

[0024] Optionally, the machine body is provided with a guide groove, which extends along the moving direction of the partition, and a portion of the partition in the unfolded state is accommodated in the guide groove.

[0025] Therefore, it can guide the movement and deployment of the partition, which helps to improve the accuracy of the partition movement and deployment, so as to accurately and effectively cover the side of the device body.

[0026] Optionally, the energy storage device further includes a first seal disposed in a guide groove to seal the partition and body in the deployed state.

[0027] Therefore, the sealing effect between the partition and the body after the device is moved and deployed can be further improved, and the coverage effect on the side of the device body can be enhanced, reducing the possibility of flames and smoke flowing out from between the partition and the body.

[0028] Optionally, the first seal may be made of silicone rubber or silicone nitrile rubber.

[0029] This gives the first seal high elasticity and high temperature resistance and fire resistance, which helps to improve the sealing effect of the first seal and reduce the possibility of damage by fire.

[0030] Optionally, in the direction intersecting the moving direction and thickness direction of the partition, the machine body is provided with guide grooves on both sides of the partition; the two guide grooves are arranged opposite to each other, and the two sides of the partition in the unfolded state are respectively accommodated in the two guide grooves.

[0031] And / or, the body is also provided with a receiving groove, one end of the guide groove being connected to the receiving groove; in a direction intersecting the moving direction and thickness direction of the partition, the end of the partition in the storage state is accommodated in the receiving groove.

[0032] Therefore, the two guide slots can guide both sides of the partition, which helps to improve the accuracy of the partition's further movement and unfolding, so as to provide more accurate and effective coverage of the side of the device body; the receiving slots can accommodate the ends of the partition in the storage state, improving the compactness of the distribution between the partition and the machine body.

[0033] Optionally, the machine body is also provided with a receiving slot, which extends along the direction intersecting the moving direction and the thickness direction of the partition;

[0034] The partition in the retracted state is located at one end of the guide groove, and the receiving groove is connected to the other end of the guide groove. The partition in the unfolded state is partially housed in the receiving groove.

[0035] This improves the sealing effect between the partition and the body when they are in the unfolded state, which in turn helps to further improve the coverage effect of the partition on the side of the device body.

[0036] Optionally, the energy storage device also includes a second seal disposed within the receiving slot to seal the partition and body in the deployed state.

[0037] This improves the sealing between the partition in its deployed state and the wall of the receiving trough.

[0038] Optionally, the second seal may be made of silicone rubber or silicone nitrile rubber.

[0039] This gives the second seal high elasticity and high temperature resistance and fire resistance, which helps to improve the sealing effect of the second seal and reduce the possibility of damage from fire.

[0040] Optionally, the driver module includes:

[0041] Rotary drive components; and

[0042] A spool is connected to a rotary drive, and a partition is wound onto the spool. The rotary drive is configured to drive the spool to rotate, thereby releasing the partition to move and unfold.

[0043] This allows the partitions to be stored by rolling them up, which improves the compactness of the partitions during storage and thus enhances the convenience of their installation and arrangement on the machine body.

[0044] Optionally, the rotary drive and the reel are located at the upper end of the machine body.

[0045] This allows the partition to be guided by its own gravity when it is released, thereby improving the convenience of the drive module in driving the partition.

[0046] Optionally, the body includes:

[0047] The main frame consists of vertical beams and horizontal beams. There are multiple vertical beams arranged circumferentially around the body, and the horizontal beams connect the multiple vertical beams.

[0048] The load-bearing component is located within and connected to the main frame, and supports the energy storage module located within the main frame.

[0049] The two ends of the scroll are rotatably connected between two adjacent vertical beams, and the partition in the unfolded state covers the communication opening formed by the two adjacent vertical beams.

[0050] Therefore, the connection port can provide ventilation and heat dissipation for the energy storage module located inside the machine body; at the same time, the vertical beam can also facilitate the setting of the roller in the drive module, thereby improving the convenience of setting the barrier mechanism and guide groove.

[0051] Optionally, the vertical beam includes an inner vertical beam and an outer vertical beam connected together, and the opposite ends of the roll are connected to two adjacent outer vertical beams;

[0052] The crossbeam includes a first crossbeam, which connects to the inner vertical beam.

[0053] Therefore, the barrier mechanism can be installed without occupying space inside the machine body, so that the required number of energy storage modules can be installed inside the machine body.

[0054] Optionally, the crossbeam also includes a second crossbeam, which includes an inner crossbeam and an outer crossbeam connected to each other. The inner crossbeam is connected to the inner vertical beam; the outer crossbeam is connected to the outer vertical beam and is arranged opposite to the scroll. The partition in the unfolded state abuts against the outer crossbeam.

[0055] And / or, the body also includes a protective shield connected to the outer vertical beam; the protective shield has a receiving space inside, and a scroll and a partition wound on the scroll are housed in the receiving space.

[0056] This allows the partition to fit snugly against the outer crossbeam after it is moved and unfolded, improving the sealing effect of the side of the device body; the protective cover can contain the roller and the partition in the storage state, reducing the possibility of damage.

[0057] Optionally, the partition includes

[0058] The plate body; and

[0059] Fireproof and heat-insulating layer, which is installed on the board body.

[0060] Therefore, the partition can have the required strength through the plate body, while the fireproof and heat-insulating layer can improve the fireproof and heat-insulating performance of the partition, further enhancing its fire-blocking effect.

[0061] Optionally, the number of fireproof and heat-insulating layers is at least two, and the at least two fireproof and heat-insulating layers are stacked along the thickness direction of the board body, and the materials of the at least two fireproof and heat-insulating layers are different.

[0062] And / or, the fireproof and heat-insulating layer is made of ceramic fiber, glass fiber or fireproof cotton;

[0063] And / or, a fireproof and heat-insulating layer is provided inside the board body, and an anti-corrosion layer is provided on the outer side of the board body;

[0064] And / or, the material of the plate body is metal.

[0065] Therefore, by setting at least two fireproof and heat-insulating layers of different materials, the performance of each fireproof and heat-insulating layer can be complementary, thereby further improving the overall fireproof and heat-insulating performance of the partition. Using ceramic fiber, glass fiber, or fire-resistant cotton as the material for the fireproof and heat-insulating layer can give the partition good fireproof and heat-insulating performance. Concealing the fireproof and heat-insulating layer within the panel body allows for a hidden installation, reducing the possibility of damage. It also facilitates the provision of a mounting location on the outside of the panel body for installing an anti-corrosion layer. This anti-corrosion layer can resist corrosion from the electrolyte ejected from the energy storage device during thermal runaway, or from the presence of acidic or alkaline gases, ensuring stable operation of the partition in such an environment. Using metal as the material for the panel body allows for easy application of an anti-corrosion layer, forming a dense protective film.

[0066] Optionally, the number of blocking mechanisms is provided in multiples, with the multiple blocking mechanisms arranged around the circumference of the machine body.

[0067] This allows for coverage of all sides of the device, thus enclosing the device and enhancing its fire-blocking effect. Attached Figure Description

[0081] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0082] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0083] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0084] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0085] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0086] With the increasing scarcity of global energy, batteries, representing new energy sources, are being widely used in fields such as mobile phones, tablets, digital cameras, electronic navigation devices, electric bicycles, electric vehicles, communication base stations, and aerospace. As battery technology continues to develop, energy storage devices capable of storing and releasing electrical energy have emerged, enabling more convenient use and control of electrical energy.

[0087] Among these technologies, energy storage devices such as energy storage valve towers are typically arranged in an array, and in order to control site costs, the spacing between energy storage devices is set to be relatively small.

[0088] However, because energy storage devices contain batteries, they are at risk of thermal runaway during operation. In such cases, the close spacing between energy storage devices means that if a fire breaks out in one device due to thermal runaway, it can easily spread to other devices, leading to greater damage.

[0089] Therefore, based on the above considerations, in order to solve the problem that when a fire caused by thermal runaway occurs in an energy storage device in the related technology, it is easy for the fire to spread to other energy storage devices and cause the disaster to escalate, this application proposes a novel energy storage device. This novel energy storage device is equipped with a barrier mechanism and a control module, which allows the control module to automatically or manually activate the drive module in the barrier mechanism to drive the partition to move and unfold, so as to cover at least part of the side of the device body, thereby isolating the energy storage device that has caught fire from the energy storage device that has not caught fire, and reducing the further spread of the fire to the energy storage device that has not caught fire.

[0090] In addition, it should be noted that the energy storage device proposed in this application can be an energy storage valve tower, or of course a charging station or energy storage cabinet, etc. This application does not limit the type of energy storage device, as long as it is a device that can be used to store electrical energy.

[0091] The following explanation uses an energy storage device as an example of an energy storage valve tower:

[0092] Please refer to the reference. Figures 1 to 6 , Figure 8 as well as Figure 9 In one embodiment of this application, the energy storage device 100 includes a device body 10, a barrier mechanism 30, and a control module 50. The device body 10 includes a body 11 and an energy storage module 13, with the energy storage module 13 disposed on the body 11. The barrier mechanism 30 is disposed on the body 11 and includes a drive module 31 and a partition 33. The partition 33 is connected to the drive module 31 and has a retracted state and an unfolded state. The drive module 31 is configured to drive the partition 33 to move and unfold to cover at least a portion of the side of the body 11. The control module 50 is disposed on the body 11 and includes a sensing module 51, a controller 53, and a manual switch 55. The sensing module 51 is disposed on the body 11 and electrically connected to the controller 53. The sensing module 51 includes at least one of a temperature sensor 511 and a smoke sensor 513. The controller 53 and the manual switch 55 are both electrically connected to the drive module 31.

[0093] The device body 10 serves as the main structure of the energy storage device 100, enabling the storage and release of electrical energy. Specifically, the body 11 within the device body 10 acts as a support structure for mounting and supporting the energy storage module 13. The energy storage module 13 stores electrical energy using its built-in battery. The body 11 can be a frame structure, as described below, including a main frame 110 and a support member 120; it can also be a shell structure. This application does not limit the structural type of the body 11. Furthermore, when the energy storage device 100 is in its normal installation state, with the ground as a reference, the projection of the body 11 onto the horizontal plane can be rectangular, square, or other shapes. This application does not limit the shape of the body 11. The energy storage module 13 can include a shell and a battery housed within the shell. Multiple batteries can be provided, and they can be connected in series, parallel, or a combination of series and parallel connections. Moreover, the number of energy storage modules 13 can be one, two, or more. In addition, the device body 10 may also include a power cabinet and a heat dissipation system. The power cabinet can convert the DC power output by the energy storage module 13 into AC power that can be transmitted to the power grid or other loads to complete the discharge and release of electrical energy. At the same time, it can also rectify the AC power of the power grid into DC power to charge and store energy for the energy storage module 13.

[0094] The barrier mechanism 30, driven by the drive module 31, provides driving force to move and unfold the partition 33, thereby providing a barrier function in the event of a fire caused by thermal runaway in the device body 10. The drive module 31 may include a rotary drive 311 and a reel 313, as described below, with the partition 33 wound onto the reel 313. The rotary drive 311 can drive the reel 313 to rotate, releasing the partition 33 and thus enabling its unfolding. Alternatively, the partition 33 can be configured as multiple sub-plates, which can be folded together for storage. The drive module 31 may include a linear drive connected to the end sub-plates of the partition 33, allowing the linear drive to move the end sub-plates and gradually unfold the entire partition 33. Therefore, the partition 33 can be in a rolled-up state or a folded state. Furthermore, the drive module 31 can drive the partition 33 to unfold vertically or horizontally. Furthermore, when the energy storage devices 100 are arranged linearly along a single direction, the energy storage devices 100 located at the edge may be provided with a barrier mechanism 30, located on the side of the energy storage device 100 facing the energy storage device 100 in the middle; while the energy storage devices 100 located in the middle may be provided with two barrier mechanisms 30, respectively located on opposite sides of the energy storage devices 100 facing the energy storage devices 100 at the edge; of course, both the energy storage devices 100 at the edge and the energy storage devices 100 in the middle may have barrier mechanisms 30 provided on all sides in the circumferential direction. When the energy storage devices 100 are arranged in an array along two intersecting horizontal directions, the energy storage devices 100 located in the middle may have barrier mechanisms 30 provided on all sides in the circumferential direction; while the energy storage devices 100 located at the edge may have barrier mechanisms 30 provided on all sides in the circumferential direction, or they may only have barrier mechanisms 30 provided on a few sides facing adjacent energy storage devices 100. Therefore, this application does not limit the number of barrier mechanisms 30 in the energy storage device 100. For example, when the body 11 in the energy storage device is projected as a rectangle or a square on the horizontal plane, barrier mechanisms 30 may be provided on one side or all four sides of the body 11. Moreover, the number of barrier mechanisms 30 provided on each side may be one, or two or more. In addition, when the partition 33 is in the unfolded state, it covers at least part of the side of the body 11. That is, when a barrier mechanism 30 is provided on a certain side of the body 11, the unfolded partition 33 may cover part or all of the side of the body 11 on that side. Furthermore, the partition 33 may include a plate body 331 and a fireproof and heat-insulating layer 333 provided on the plate body 331, as described below, or it may further include an anti-corrosion layer 335. Of course, it may also only include the plate body 331, which may be made of high-temperature resistant and flame-retardant materials, such as metal or fireproof cotton felt.When the material of the plate body 331 is metal, the thickness of the plate body 331 can be set to be relatively thin so that it can be rolled up or folded to have a storage state.

[0095] The control module 50 can be used for automatic and manual control of the activation of the isolation mechanism 30. Specifically, the temperature sensor 511 and / or smoke sensor 513 in the sensing module 51 can detect the temperature and / or smoke of the device body 10 and transmit the temperature signal and / or smoke signal to the controller 53. The controller 53 determines that the energy storage device 100 has experienced thermal runaway and caused a fire based on the temperature signal exceeding a preset threshold and / or the smoke signal, and can then automatically control the activation of the drive module 31 in the isolation mechanism 30. Of course, in some emergency situations, the drive module 31 in the isolation mechanism 30 can also be manually activated by pressing or rotating the manual switch 55. Moreover, when the energy storage device 100 is provided with multiple isolation mechanisms 30, multiple isolation mechanisms 30 can be controlled simultaneously by one control module 50 to improve the convenience of controlling multiple isolation mechanisms 30 and simplify the structural configuration of the energy storage device 100. In addition, the controller 53 can be installed at any position on the body 11, or it can be installed on other objects. Similarly, the manual switch 55 can be set at any position on the body 11, or it can be set on other objects.

[0096] The energy storage device 100 of this application has a barrier mechanism 30 on its body 11. This allows the energy storage device 100 to, in the event of a fire caused by thermal runaway, have a partition 33 moved and deployed via a drive module 31 in the barrier mechanism 30 to cover at least a portion of the side of the body 11. Figure 3As shown. At this time, the partition 33 can isolate the energy storage device 100 that has caught fire from the energy storage device 100 that has not caught fire, thus preventing the fire from spreading further to the energy storage device 100 that has not caught fire. Furthermore, the energy storage device 100 in this solution also includes a control module 50, which includes a sensing module 51, a controller 53, and a manual switch 55. The sensing module 51, including at least one of a temperature sensor 511 and a smoke sensor 513, can detect whether thermal runaway has occurred, triggering the controller 53 to promptly activate the drive module 31 to move and unfold the partition 33 to prevent the fire from spreading. The manual switch 55 allows for manual activation of the drive module 31 to move and unfold the partition 33 in an emergency to prevent the fire from spreading. Therefore, the inclusion of the control module 50 facilitates the timely activation of the isolation mechanism 30, thereby further reducing the possibility of fire spread. Furthermore, the sensing module 51 may include only a temperature sensor 511, only a smoke sensor 513, or both a temperature sensor 511 and a smoke sensor 513. The number of temperature sensors 511 may be one, or two or more. Similarly, the number of smoke sensors 513 may be one, or two or more. Additionally, the temperature sensor 511 may be located at the top, bottom, or middle of the body 11; the location of the temperature sensor 511 is not limited in this application. Similarly, the smoke sensor 513 may be located at the top, bottom, or middle of the body 11; the location of the smoke sensor 513 is not limited in this application.

[0097] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, there are multiple temperature sensors 511, including a top temperature sensor 511A and a bottom temperature sensor 511B; the top temperature sensor 511A is located at the top of the body 11, and the bottom temperature sensor 511B is located at the bottom of the body 11.

[0098] The top end of the body 11, that is, the end of the body 11 located near the top surface, includes both the inner and outer sides of this end. The bottom end of the body 11, that is, the end of the body 11 located near the bottom surface, includes both the inner and outer sides of this end. The number of top temperature sensors 511A can be one, or two or more, and they can be located on the same wall surface of the body 11 or distributed on different walls of the body 11. Similarly, the number of bottom temperature sensors 511B can be one, or two or more, and they can be located on the same wall surface of the body 11 or distributed on different walls of the body 11.

[0099] In this embodiment, the temperature sensor 511 is configured to include a top temperature sensor 511A and a bottom temperature sensor 511B, which are respectively disposed at the top and bottom of the body 11, so that the temperature of the device body 10 can be detected in sections, thereby improving the accuracy of the overall temperature detection of the device body 10.

[0100] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the plurality of temperature sensors 511 further includes a central temperature sensor 511C, which is disposed between the top and bottom ends of the body 11.

[0101] The temperature sensor 511A is located between the top and bottom ends, which is the middle position of the body 11 in the vertical direction. Therefore, the top temperature sensor 511A, the middle temperature sensor 511C, and the bottom temperature sensor 511B are arranged sequentially from top to bottom. The middle position of the body 11 in the vertical direction includes both the inner and outer sides of the body 11. Furthermore, when a communication port 110a is provided on the side of the body 11 as described below, the middle position of the body 11 in the vertical direction also includes the wall surface that encloses and forms the communication port 110a. Additionally, the number of middle temperature sensors 511C can be one, two, or more, and they can be located on the same wall surface of the body 11 or distributed on different walls of the body 11.

[0102] In this embodiment, a central temperature sensor 511C is further provided between the top and bottom of the body 11, which enables more precise temperature detection of the device body 10 in different zones, thereby improving the accuracy of overall temperature detection of the device body 10.

[0103] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, there are multiple top temperature sensors 511A, and at least some of the top temperature sensors 511A are arranged around the body 11 in a circumferential manner.

[0104] In this embodiment, multiple top temperature sensors 511A are arranged to surround the body 11 circumferentially, allowing for further circumferential temperature detection at the top of the body 11, thereby improving the accuracy of overall temperature detection of the device body 10. At least some of the top temperature sensors 511A are arranged circumferentially around the body 11; that is, all of the top temperature sensors 511A may be arranged circumferentially around the body 11, or some may be positioned at the midpoint of the top of the body 11 on the horizontal plane. For example, when the body 11 is a frame structure including crossbeams 115 as described below, some of the crossbeams 115 may be located within the space enclosed by multiple vertical beams 111, and some of the top temperature sensors 511A may be located on the crossbeams 115 within the space enclosed by the multiple vertical beams 111.

[0105] Similarly, in order to further divide the body 11 into circumferential zones for temperature detection, please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, there are multiple central temperature sensors 511C, and at least some of the central temperature sensors 511C are arranged around the body 11 in a circumferential manner.

[0106] To further divide the bottom of the unit 11 into circumferential zones for temperature detection, please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, there are multiple bottom temperature sensors 511B, and at least some of the bottom temperature sensors 511B are arranged around the body 11 in a circumferential manner.

[0107] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the smoke sensor 513 is disposed at the top of the body 11.

[0108] In this embodiment, the smoke sensor 513 is positioned at the top of the body 11. Since the smoke stream generated when the device body 10 catches fire due to thermal runaway typically flows upwards, this placement of the smoke sensor 513 facilitates timely and accurate smoke detection. The number of smoke sensors 513 can be one, or two or more, and they can be located on the same wall of the body 11 or distributed across different walls of the body 11.

[0109] Please refer to the reference. Figure 1 and Figure 2In one embodiment of this application, there are multiple smoke sensors 513, and at least some of the smoke sensors 513 are arranged around the circumference of the body 11.

[0110] In this embodiment, multiple smoke sensors 513 are arranged to surround the body 11 circumferentially, allowing for circumferentially zoned smoke detection at the top of the body 11, thereby improving the accuracy of smoke detection for the entire device body 10. At least some of the smoke sensors 513 are arranged circumferentially around the body 11; that is, all smoke sensors 513 can be arranged circumferentially around the body 11, or some smoke sensors 513 can be positioned at the midpoint of the top of the body 11 on the horizontal plane. For example, some smoke sensors 513 can be located on a horizontal beam 115 within the space enclosed by multiple vertical beams 111.

[0111] Please refer to the reference. Figures 2 to 6 In one embodiment of this application, the body 11 is provided with a guide groove 1131, which extends along the moving direction of the partition 33, and a portion of the partition 33 in the unfolded state is accommodated in the guide groove 1131.

[0112] The guide groove 1131 extends along the moving direction of the partition 33, ensuring that the partition 33 can only move along the extending direction of the guide groove 1131 when it is driven to move and unfold. Specifically, the guide groove 1131 can extend vertically when the partition 33 moves and unfolds vertically, and it can also extend horizontally when the partition 33 moves and unfolds horizontally. Furthermore, on a projection plane perpendicular to the moving direction of the partition 33, the shape of the guide groove 1131 can be adapted to the shape of the portion of the partition 33 accommodated within the guide groove 1131, for example, both being rectangular or square, to improve the guiding effect of the partition 33's movement and unfolding, while also simplifying the shape of the guide groove 1131 and improving its ease of processing. Furthermore, for each partition 33, the number of guide grooves 1131 can be set to one to guide the partition 33 on one side; of course, the number of guide grooves 1131 can also be set to two to achieve double-sided guidance of the partition 33 as described below. It should also be noted that the partition 33 in the retracted state can be partially housed within the guide grooves 1131, so that the partition 33 can move quickly and accurately along the extension direction of the guide grooves 1131 when it is subsequently moved and unfolded. Alternatively, the partition 33 in the retracted state can also be not housed within the guide grooves 1131, only entering the guide grooves 1131 when it is subsequently driven to move and unfold.

[0113] In this embodiment, the guide groove 1131 can guide the movement and unfolding of the partition 33, which helps to improve the accuracy of the movement and unfolding of the partition 33, so as to accurately and effectively cover the side of the device body 10, thereby improving the blocking effect of the device body 10 in the event of a fire.

[0114] Please refer to the reference. Figure 6 and Figure 7 In one embodiment of this application, the energy storage device 100 further includes a first sealing member 70, which is disposed in the guide groove 1131 to seal the partition 33 and the body 11 in the unfolded state.

[0115] The first sealing element 70 can be used to seal the space between the partition 33 and the groove wall of the guide groove 1131 after the partition 33 is moved and unfolded. The first sealing element 70 can be at least one of two opposing groove walls of the guide groove 1131 in the thickness direction of the partition 33, or it can be a groove wall corresponding to the opening of the guide groove 1131. Furthermore, the material of the first sealing element 70 can be elastic silicone or rubber to achieve a sealing effect. Alternatively, the material of the first sealing element 70 can be silicone rubber or silicone nitride rubber, as described below, which further possesses high-temperature resistance and fire-retardant properties. That is, this application does not limit the material of the first sealing element 70.

[0116] In this embodiment, the first sealing member 70 can seal the space between the partition 33 and the body 11 after the partition is moved and unfolded, further improving the coverage effect on the side of the device body 10, reducing the possibility of flames and smoke flowing out between the partition 33 and the body 11, and further improving the blocking effect on the device body 10 in the event of a fire.

[0117] In one embodiment of this application, the first sealing element 70 is made of silicone rubber or silicone nitride rubber.

[0118] In this embodiment, using silicone rubber or silicone-nitrogen rubber as the material of the first sealing element 70 can give the first sealing element 70 high elasticity and high temperature fire resistance, thereby improving the sealing effect of the first sealing element 70 and reducing the possibility of damage by fire.

[0119] In one embodiment of this application, in the direction intersecting the moving direction and the thickness direction of the partition 33, the body 11 is provided with guide grooves 1131 on both sides of the partition 33; the two guide grooves 1131 are arranged opposite to each other, and the two sides of the partition 33 in the unfolded state are respectively accommodated in the two guide grooves 1131.

[0120] The thickness direction of partition 33 refers to the thickness direction defined when partition 33 is in the unfolded state.

[0121] In this embodiment, by providing two guide grooves 1131, the partition 33 can be guided on both sides, thereby improving the accuracy of the partition 33's further movement and unfolding, so as to provide more accurate and effective coverage of the sides of the device body 10. At this time, the first sealing element 70 described above can be provided in both guide grooves 1131 to further improve the coverage effect of the partition 33 on the sides of the device body 10.

[0122] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the body 11 is further provided with a receiving groove 1133, and one end of the guide groove 1131 is connected to the receiving groove 1133; in the direction intersecting the moving direction and the thickness direction of the partition 33, the end of the partition 33 in the storage state is accommodated in the receiving groove 1133.

[0123] When the partition 33 is in its retracted state and located at the upper end of the body 11, allowing it to move and unfold in the vertical direction, the receiving groove 1133 can be positioned at the upper end of the guide groove 1131. The receiving groove 1133 can be adapted to the shape of the partition 33 in its retracted state. For example, when the partition 33 is retracted, the receiving groove 1133 can be circular.

[0124] In this embodiment, by providing a receiving groove 1133 that communicates with the guide groove 1131, the end of the partition 33 in the storage state is accommodated, which can improve the compactness of the distribution between the partition 33 and the body 11, and also facilitate the alignment of the partition 33 and the guide groove 1131.

[0125] Please refer to the reference. Figures 2 to 6 In one embodiment of this application, the body 11 is further provided with a receiving groove 1191, which extends along the direction intersecting the moving direction and thickness direction of the partition 33; the partition 33 in the stored state is provided at one end of the guide groove 1131, the receiving groove 1191 is connected to the other end of the guide groove 1131, and a portion of the partition 33 in the unfolded state is accommodated in the receiving groove 1191.

[0126] The receiving groove 1191 can accommodate and receive the moving end of the partition 33. For example, when the partition 33 moves and unfolds in the vertical direction, the receiving groove 1191 can accommodate and receive the lower end of the partition 33. The receiving groove 1191 and the receiving groove 1133 described above can be connected to opposite ends of the guide groove 1131. For example, when the receiving groove 1133 is located at the upper end of the guide groove 1131 as described above, the receiving groove 1191 can be located at the lower end of the guide groove 1131. In this case, when there is only one guide groove 1131, the receiving groove 1191 and the guide groove 1131 can form an L-shape in the thickness direction of the partition 33; when there are two guide grooves 1131 arranged opposite each other, the receiving groove 1191 and the guide groove 1131 can form a U-shape in the thickness direction of the partition 33.

[0127] In this embodiment, by setting a receiving slot 1191 to receive the end of the partition 33 that is moved and unfolded, the sealing effect between the partition 33 and the body 11 in the unfolded state can be improved, which in turn helps to further improve the coverage effect of the partition 33 on the side of the device body 10.

[0128] To further improve the sealing between the partition 33 in its deployed state and the wall of the receiving trough 1191, please refer to the reference. Figure 6 and Figure 7 In one embodiment of this application, the energy storage device 100 may further include a second seal 90, which is disposed in the receiving groove 1191 to seal the partition 33 and the body 11 in the unfolded state.

[0129] The second sealing element 90 can be at least one of two opposing groove walls of the receiving groove 1191 in the thickness direction of the partition 33, or it can be a groove wall corresponding to the opening of the receiving groove 1191. The material of the second sealing element 90 can be elastic silicone or rubber to provide a sealing effect. Alternatively, the material of the second sealing element 90 can be silicone rubber or silicone nitride rubber with high-temperature resistance and fireproof properties. That is, this application does not limit the material of the second sealing element 90. Furthermore, the second sealing element 90 and the first sealing element 70 can be an integral structure. That is, they can be manufactured using an integral molding process (e.g., injection molding), so that they form a whole after manufacturing. Alternatively, the second sealing element 90 and the first sealing element 70 can be separate structures manufactured separately.

[0130] Please refer to Figure 8In one embodiment of this application, the drive module 31 includes a rotary drive 311 and a reel 313; the reel 313 is connected to the rotary drive 311, the partition 33 is wound onto the reel 313, and the rotary drive 311 is configured to drive the reel 313 to rotate so as to release the partition 33 to move and unfold.

[0131] The rotary drive 311 provides rotational driving force to drive the spool 313 to rotate. The rotary drive 311 can be a motor or a rotary cylinder; this application does not limit the type of rotary drive 311. The spool 313 is used to wind up the mounting partition 33, so that the partition 33 is in a retracted state; subsequently, when the spool 313 is driven to rotate by the rotary drive 311, the partition 33 can be released, realizing the movement and unfolding of the partition 33. The axial end of the spool 313 can be rotatably mounted within the receiving groove 1133 described above.

[0132] In this embodiment, the drive module 31 is configured to include a rotary drive component 311 and a reel 313, allowing the partition 33 to be stored by winding. This improves the compactness of the partition 33 during storage, thereby enhancing the ease of installation on the body 11. Furthermore, the partition 33 can be released and unfolded simply by rotating the reel 313 via the rotary drive component 311. This simple driving method further simplifies the structure of the drive module 31, improving its manufacturing and installation convenience.

[0133] Please refer to Figure 8 In one embodiment of this application, the drive module 31 may further include a transmission component 315, which may include a drive wheel 3151, a driven wheel 3153 and a belt 3155. The drive wheel 3151 may be connected to the rotary drive member 311, the driven wheel 3153 may be connected to the reel 313, and the belt 3155 may be wound around the drive wheel 3151 and the driven wheel 3153.

[0134] In this embodiment, by using a transmission assembly 315 to connect the rotary drive 311 and the reel 313, the requirements for the placement of the rotary drive 311 are reduced, increasing the flexibility of its installation. Furthermore, the transmission assembly 315 can be used to adjust the transmission ratio, thereby obtaining sufficient torque to improve the ease of driving the partition 33. For example, the diameter of the driving wheel 3151 can be set smaller than the diameter of the driven wheel 3153. Of course, this application is not limited to this; in other embodiments, the transmission assembly 315 can also be a gear set.

[0135] Please refer to the reference. Figure 3 and Figure 8In one embodiment of this application, the rotary drive 311 and the reel 313 are disposed at the upper end of the body 11.

[0136] In this embodiment, the rotation drive 311 is disposed at the upper end of the body 11, so that the partition 33 can play a guiding role under the gravity of the partition 33 when it is released, thereby improving the convenience of the drive module 31 to drive the partition 33.

[0137] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the body 11 includes a main frame 110 and a support member 120. The main frame 110 includes vertical beams 111 and horizontal beams 115. There are multiple vertical beams 111, which are arranged around the circumference of the body 11. The horizontal beams 115 connect multiple vertical beams 111. The support member 120 is disposed inside the main frame 110 and connected to the main frame 110. The support member 120 is supported by an energy storage module 13 disposed inside the main frame 110. The two ends of the roller 313 are rotatably connected between two adjacent vertical beams 111. The partition 33 in the unfolded state covers the communication opening 110a formed by the two adjacent vertical beams 111.

[0138] The main frame 110 is enclosed by multiple vertical beams 111 to form a space, and the multiple vertical beams 111 are connected by horizontal beams 115 to form a whole. When the projection of the body 11 onto the horizontal plane is rectangular or square, there can be four, five, or more vertical beams 111. The horizontal beams 115 can be located between two adjacent vertical beams 111, and can be provided at the top, bottom, and middle of the body 11. The support member 120 can be used to support the energy storage module 13. That is, the energy storage module 13 can be placed on the support member 120. The support member 120 can be a plate structure or a column structure; this application does not limit the structural type of the support member 120. The support member 120 can be connected to the vertical beams 111, the horizontal beams 115, or both.

[0139] In this embodiment, the body 11 includes a main frame 110 and a support member 120, which allows for ventilation and heat dissipation of the energy storage module 13 located within the body 11 through the communication port 110a. This also simplifies the structure of the body 11, improving manufacturing convenience and reducing costs. Furthermore, the vertical beam 111 facilitates the placement of the roller 313 in the drive module 31 and the guide groove 1131 described above, thereby improving the ease of setting up the barrier mechanism 30 and the guide groove 1131.

[0140] Please refer to the reference. Figures 1 to 4 In one embodiment of this application, the vertical beam 111 includes an inner vertical beam 112 and an outer vertical beam 113 connected to each other, and the two opposite ends of the scroll 313 are connected to two adjacent outer vertical beams 113; the horizontal beam 115 includes a first horizontal beam 116, which is connected to the inner vertical beam 112.

[0141] The inner vertical beam 112 is located closer to the inner side of the body 11 than the outer vertical beam 113. The first crossbeam 116 can be used to connect the inner vertical beam 112, so that it and the inner vertical beam 112 enclose a space for installing the energy storage module 13.

[0142] In this embodiment, the two ends of the axial direction of the reel 313 are rotatably mounted on the two outer vertical beams 113, which ensures that the blocking mechanism 30 does not occupy the space inside the body 11, so that the required number of energy storage modules 13 can be installed inside the body 11. In addition, the guide groove 1131 and the receiving groove 1133 described above can be provided on the outer vertical beams 113.

[0143] Please refer to the reference. Figures 1 to 4 In one embodiment of this application, the crossbeam 115 further includes a second crossbeam 117, which includes an inner crossbeam 118 and an outer crossbeam 119 connected to each other. The inner crossbeam 118 is connected to the inner vertical beam 112; the outer crossbeam 119 is connected to the outer vertical beam 113 and is disposed opposite to the scroll 313. The partition 33 in the unfolded state abuts against the outer crossbeam 119.

[0144] In this embodiment, by further providing a second crossbeam 117, which includes an inner crossbeam 118 and an outer crossbeam 119, the partition 33 can fit against the outer crossbeam 119 after being moved and unfolded, thereby improving the sealing effect of covering the side of the device body 10. Additionally, the receiving groove 1191 described above can be provided on the outer crossbeam 119.

[0145] Please refer to the reference. Figures 4 to 6 ,as well as Figure 8 In one embodiment of this application, the body 11 further includes a protective cover 35, which is connected to the outer vertical beam 113; the protective cover 35 has a receiving space 351, and the scroll 313 and the partition 33 wound on the scroll 313 are housed in the receiving space 351.

[0146] The protective cover 35 can extend along the axial direction of the scroll 313. Moreover, the projection of the protective cover 35 in the axial direction of the scroll 313 can be L-shaped to simplify the shape and structure of the protective cover 35. Of course, the projection of the protective cover 35 can be either L-shaped or U-shaped, and the orientation of the U-shaped opening is the same as the direction of movement and unfolding of the partition 33.

[0147] In this embodiment, the protective cover 35 serves to contain the scroll 313 and the partition 33 in its stored state, reducing the possibility of damage. Additionally, the protective cover 35 provides a mounting position for mounting the rotary drive 311 onto its upper surface.

[0148] Please refer to Figure 10 In one embodiment of this application, the partition 33 includes a plate body 331 and a fireproof and heat-insulating layer 333; the fireproof and heat-insulating layer 333 is disposed on the plate body 331.

[0149] In this embodiment, the partition 33 is configured to include a plate body 331 and a fireproof and heat-insulating layer 333. The plate body 331 enables the partition 33 to have the required strength, while the fireproof and heat-insulating layer 333 improves the fireproof and heat-insulating performance of the partition 33, further enhancing its fire-blocking effect. The fireproof and heat-insulating layer 333 can be disposed on the inner or outer side of the plate body 331; this application does not limit the placement of the fireproof and heat-insulating layer 333. Furthermore, the material of the fireproof and heat-insulating layer 333 can be ceramic fiber, glass fiber, mica, or fireproof cotton, etc., which have good fireproof and heat-insulating properties; this application also does not limit the material of the fireproof and heat-insulating layer 333.

[0150] Please refer to Figure 10 In one embodiment of this application, the number of fireproof and heat-insulating layers 333 is at least two layers, and the at least two fireproof and heat-insulating layers 333 are stacked along the thickness direction of the board body 331, and the materials of the at least two fireproof and heat-insulating layers 333 are different.

[0151] In this embodiment, at least two fireproof and heat-insulating layers 333 are configured, and the materials of the at least two fireproof and heat-insulating layers 333 are different. For example, one fireproof and heat-insulating layer 333 is made of ceramic fiber, and the other fireproof and heat-insulating layer 333 is made of fireproof cotton. This allows the fireproof and heat-insulating layers 333 to complement each other in performance, thereby further improving the overall fireproof and heat-insulating performance of the partition 33.

[0152] Please refer to Figure 10 In one embodiment of this application, a fireproof and heat-insulating layer 333 is disposed inside the plate body 331, and an anti-corrosion layer 335 is disposed on the outer side of the plate body 331.

[0153] In this embodiment, the fireproof and heat-insulating layer 333 is disposed within the plate body 331, allowing for a concealed installation and reducing the possibility of damage. Simultaneously, it facilitates the provision of a mounting location on the outer side of the plate body 331 for the installation of the anti-corrosion layer 335. The anti-corrosion layer 335 provides corrosion resistance against the electrolyte ejected from the energy storage device 100 during thermal runaway, as well as against the erosion of acidic or alkaline gases present, ensuring stable operation of the partition 33 in such an environment. The anti-corrosion layer 335 can be a polyurethane coating, a fluorocarbon anti-corrosion coating, or an alumina coating, etc.; this application does not limit the material type of the anti-corrosion layer 335. Furthermore, to facilitate the coating of the anti-corrosion layer 335 onto the plate body 331 and the formation of a dense protective film, the plate body 331 can be made of metal.
