[0003] With the rapid development of technology, electricity has become an indispensable energy source in people's production and daily life. To improve the smoothness of electricity supply and ensure the normal operation of production and daily life, energy storage devices are needed. As devices for storing electrical energy, energy storage devices store electrical energy or supply the stored energy to electrical devices through charging or discharging. Energy storage devices are widely used in industrial power supply, household power supply, temporary power supply, mobile power supply, wind power generation, solar power generation, and energy storage power stations.

[0004] In the development of energy storage devices, how to improve the ease of assembly of the installation compartment is a technical issue that needs continuous improvement. Summary of the Invention

[0005] The purpose of this application is to provide an energy storage device, an energy storage system, an electrical device, and a charging network, in order to solve the technical problem of poor ease of assembly during installation. Technical solutions

[0006] The technical solution adopted in the embodiments of this application is:

[0007] In a first aspect, this application provides an energy storage device, including a battery device and an installation compartment, the installation compartment comprising:

[0008] A frame component, including a frame body and a first limiting structure connected to the frame body;

[0009] The bracket assembly includes multiple brackets, each bracket assembly including a bracket body and a second limiting structure connected to the bracket body. The bracket body is disposed on the frame body and is used to support the battery device. The first limiting structure and the second limiting structure are inserted to restrict the movement of the bracket body relative to the frame body.

[0010] A locking structure connects the bracket body and the frame body.

[0011] In this embodiment, the bracket body is connected to the frame body to support the battery device. When the bracket body and the frame body are assembled, the first limiting structure and the second limiting structure can be inserted to realize the positioning and initial limiting between each bracket body and the frame body. After each bracket body is limited on the frame body, the bracket body and the frame body are locked and fixed by the locking structure. This makes the assembly and fastening sequence between the bracket body and the frame body more reasonable, thereby improving the convenience of assembling the bracket assembly and the frame assembly and improving work efficiency.

[0012] In one embodiment, either the first limiting structure or the second limiting structure is a concave structure, and the other is a convex structure, with the convex structure and the concave structure interlocking.

[0013] In this embodiment, the first limiting structure and the second limiting structure adopt a protruding structure and a concave structure, respectively. The structure is simple, easy to manufacture, and helps to reduce the processing difficulty and manufacturing cost.

[0014] In one embodiment, the protruding structure includes a plug arm and a limiting arm connected to the plug arm, the plug arm and the limiting arm being arranged at an angle; the concave structure is a hole structure, the plug arm is inserted into the hole structure, and the limiting arm is blocked outside the hole structure to prevent the plug arm from detaching from the hole structure.

[0015] In this embodiment, the protruding structure adopts a combination of a plug-in arm and a limiting arm, so that while the plug-in arm is plugged into the hole structure, the limiting arm can also limit the plug-in plate, making the protruding structure less likely to come out of the hole structure and improving the reliability of the connection.

[0016] In one embodiment, the locking structure is riveted or threaded between the bracket body and the frame body.

[0017] In this embodiment, the bracket body and the frame body are connected and fixed by threaded connection or riveting, which helps to improve the convenience of assembly.

The two bracket portions are disposed on the frame body and are used to jointly support the battery device. Each bracket portion is connected to a second limiting structure, and each bracket portion is connected to the frame body through a locking structure.

[0019] In this embodiment, the bracket body adopts a structure in which two bracket parts are combined, which makes the assembly between the bracket body and the frame body more flexible and simplifies the overall structure of the frame body, thus helping to reduce the weight of the bracket body.

[0020] In one embodiment, both bracket sections are beam structures.

[0021] In this embodiment, the bracket section adopts a beam structure to facilitate manufacturing, which helps to reduce manufacturing costs and the weight of the installation compartment.

The first and second support arms extend along a first direction and are set at an angle. A second limiting structure is connected to the first support arm, and a locking structure is connected between the first support arm and the frame body. The second support arm is used to support the battery device.

[0023] In this embodiment, the bracket adopts a combination of a first support arm and a second support arm connected at an angle. The battery device is supported by the second support arm, making the overall structure of the bracket simple and easy to manufacture.

[0024] In one embodiment, there are multiple second limiting structures, which are spaced apart along a first direction; there are multiple first limiting structures, each of which is inserted and engaged with each of the second limiting structures.

[0025] In this embodiment, by setting multiple second limiting structures and first limiting structures that are plugged into and cooperate with them, multiple plugging connection positions are formed between the first support arm and the frame body, thereby improving the reliability of the connection between the first support arm and the frame body.

[0026] In one embodiment, the frame body includes a plurality of frame sections, which are arranged sequentially at intervals along a second direction. Each frame section is connected to the first limiting structure. One or more bracket bodies are provided between any two adjacent frame sections. The two ends of the bracket body opposite to the frame section are respectively connected to the second limiting structure. Each frame section is connected to the bracket body through the locking structure.

[0027] In this embodiment, multiple bracket bodies are connected between two adjacent frame sections. The two sides of the frame section located between the first and last ends can be connected to a connecting end of a bracket body, which helps to simplify the structure of the frame body, reduce the number of beam sections, and reduce the weight of the installation compartment.

[0028] In one embodiment, the installation compartment includes multiple compartment sections, each of which includes the frame assembly, the bracket assembly, and the locking structure. The multiple compartment sections are arranged sequentially along a second direction. Each frame body includes two spaced-apart opposing frame sections. Each frame section is connected to the first limiting structure. The two ends of the bracket body opposite to the two frame sections are respectively connected to the second limiting structure. Each frame section is connected to the bracket body through the locking structure.

[0029] In this embodiment, the installation compartment is formed by assembling multiple modular compartment components, which allows the installation compartment to be assembled in a modular manner, thereby improving the flexibility and convenience of assembling the overall structure of the installation compartment.

[0030] In one embodiment, each frame portion includes a plurality of spaced-apart support columns, at least one support column in each frame portion is connected to a first limiting structure, and at least one support column in each frame portion is connected to the bracket body by a locking structure.

[0031] In this embodiment, the frame section adopts a combination of multiple support columns at intervals, which helps to simplify the structure of the frame section and reduce the overall weight of the installation compartment.

[0032] In one embodiment, the support column extends along a third direction, and multiple bracket bodies are spaced apart in the third direction. Each bracket body is connected to a first limiting structure, and the third direction is perpendicular to the second direction.

[0033] In this embodiment, multiple bracket bodies are provided, each of which can support the battery device, thereby enabling the installation compartment to accommodate more battery devices and increasing the energy storage capacity of the energy storage device.

[0034] In one embodiment, the frame body includes a plurality of inter-frame sections, which are arranged sequentially at intervals along a second direction. Each frame section includes a plurality of spaced-apart support columns, and at least one support column in each frame section is connected to a first limiting structure. A bracket section in the bracket body is connected to at least one support column in a frame section through a locking structure.

[0035] In this embodiment, the bracket and the support column are connected and limited by the first limiting structure and the second limiting structure, and are also locked and fixed by the locking structure, which helps to improve the reliability and convenience of the connection between the bracket and the support column.

[0062] With the rapid development of technology, electricity has become an indispensable energy source in people's production and daily life. To improve the smoothness of electricity supply and ensure the normal operation of production and daily life, energy storage devices are needed. As devices for storing electrical energy, energy storage devices store electrical energy or supply the stored energy to electrical devices through charging or discharging. Energy storage devices are widely used in industrial power supply, household power supply, temporary power supply, mobile power supply, wind power generation, solar power generation, and energy storage power stations.

[0063] In the development of energy storage devices, how to improve the ease of assembly of the installation compartment is a technical issue that needs continuous improvement.

[0064] Energy storage devices typically include mounting compartments for housing or supporting battery units. The battery units are supported by brackets within the mounting compartment, with one bracket supporting one battery unit. Generally, multiple battery units are installed within the mounting compartment, requiring the assembly of numerous brackets. In related technologies, each bracket is welded to a frame within the mounting compartment. During assembly, the brackets are initially stacked around the frame, and operators must frequently and sequentially remove and reposition the brackets to ensure their relative positions with the frame before welding. After installing one bracket, the process is repeated with the next. Therefore, the assembly process described above is cumbersome, inconvenient, and detrimental to work efficiency.

[0065] Therefore, this application provides an energy storage device in which a second limiting structure is connected to the bracket body of the mounting compartment, and correspondingly, a first limiting structure is connected to the frame body. When the bracket assembly and the frame assembly are assembled, the second limiting structure on the bracket body and the first limiting structure on the frame body are inserted and limited, so that each bracket body can be assembled and limited on the frame body first, and then each bracket body and the frame body are locked and fixed by a locking structure. This makes the assembly sequence between the frame assembly and the bracket assembly more reasonable, improves the convenience of assembly between the bracket assembly and the frame assembly, and improves work efficiency. In addition, the connection between the first limiting structure and the second limiting structure can also increase the connection and limiting position between the frame body and the bracket body, and in conjunction with the locking structure, can further enhance the reliability of the connection between the frame body and the bracket body.

[0066] According to some embodiments of this application, referring to Figures 1, 2, 6 and 11, the energy storage device 1000 includes a battery device 1100 and a mounting compartment 1200. The mounting compartment 1200 includes a frame assembly 1300, a bracket assembly 1400, and a locking structure 1500. The frame assembly 1300 includes a frame body 1310 and a first limiting structure 1320 connected to the frame body 1310. Multiple bracket assemblies 1400 are provided, each including a bracket body 1410 and a second limiting structure 1420 connected to the bracket body 1410. The bracket body 1410 is disposed on the frame body 1310 and used to support the battery device 1100. The first limiting structure 1320 and the second limiting structure 1420 are interlocked to restrict the movement of the bracket body 1410 relative to the frame body 1310. The locking structure 1500 connects the bracket body 1410 and the frame body 1310.

[0067] For battery device 1100, battery device 1100 may include one or more battery clusters to increase the voltage and capacity of energy storage device 1000. A battery cluster may include multiple individual battery cells connected in series via a busbar to increase the voltage of energy storage device 1000. When battery device 1100 includes multiple battery clusters, the multiple battery clusters are connected in parallel to increase the capacity of energy storage device 1000.

[0068] A battery apparatus (or battery device 1100) may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar. A battery cell assembly may also be a battery module, which is formed by arranging and fixing multiple battery cells into a single module. As an example, a battery module may be formed by bundling multiple battery cells together with cable ties. The housing provides storage space for the battery cell assembly and may take various structural forms.

[0069] The battery (or battery pack 1100) can be a battery pack, which generally includes a housing and one or more individual battery cells, which are housed within the housing. The housing is housed within the mounting compartment 1200 and supported by bracket bodies 1410 within the mounting compartment 1200. Due to the large capacity of the energy storage device 1000, the number of battery cells 1100 that need to be installed in the energy storage device 1000 is also increasing. Correspondingly, a large number of bracket bodies 1410 need to be installed in the mounting compartment 1200 to support the battery cells 1100.

[0070] For the installation compartment 1200, the installation compartment 1200 includes a frame assembly 1300 and a bracket assembly 1400. The frame assembly 1300 includes a frame body 1310 and a first limiting structure 1320. The first limiting structure 1320 can be fixedly or detachably connected to the frame body 1310, or the first limiting structure 1320 can be integrally formed on the frame body 1310.

[0071] The frame body 1310 can be formed by enclosing a plate structure, so that the frame structure forms a cavity structure with an open opening. The bracket body 1410 is connected to the frame body 1310, thereby forming a slot structure that can accommodate the battery device 1100. When it is necessary to accommodate multiple battery devices 1100, multiple bracket assemblies 1400 are correspondingly provided. Each bracket assembly 1400 includes a bracket body 1410 and a second limiting structure 1420. Multiple bracket bodies 1410 are spaced apart and connected to the frame body 1310, so that the bracket bodies 1410 and the frame body 1310 together enclose multiple slot structures, and each slot structure can accommodate at least one battery device 1100. The frame body 1310 can also be formed by multiple independent column structures, so that the frame body 1310 forms a mesh or hollow frame, which helps to reduce weight; the bracket body 1410 can be connected to multiple column structures to form a groove structure with hollowed-out groove walls. The connection between multiple bracket bodies 1410 and column structures can form multiple groove structures, which can be used to accommodate more battery devices 1100.

[0072] When the bracket body 1410 is connected to the frame body 1310, the first limiting structure 1320 and the second limiting structure 1420 are inserted and limited, so that the bracket body 1410 can be limited on the frame body 1310. For example, if the frame body 1310 is placed vertically and the insertion direction of the first limiting structure 1320 and the second limiting structure 1420 is horizontal, then the bracket body 1410 is inserted into the frame body 1310 in the horizontal direction, and the frame body 1310 limits the bracket body 1410 in the vertical direction, so that the position of the bracket body 1410 relative to the frame body 1310 is fixed.

[0073] Each bracket assembly 1400 includes a bracket body 1410 and a second limiting structure 1420. The second limiting structure 1420 can be fixedly or detachably connected to the bracket body 1410, or the second limiting structure 1420 can be integrally formed on the bracket body 1410. The bracket body 1410 can be a plate-like structure, and the entire surface of the plate-like structure can form a support surface for the battery device 1100. The bracket body 1410 can also be a combined structure or an assembly structure, so that multiple connected or unconnected support surfaces are formed on the bracket body 1410, and the multiple support surfaces together support the battery device 1100. Multiple second limiting structures 1420 may be provided on the bracket body 1410. Correspondingly, the number of first limiting structures 1320 on the frame body 1310 is the same as the number of second limiting structures 1420. Each first limiting structure 1320 is inserted into the corresponding second limiting structure 1420, thereby forming multiple connection and limiting positions between the bracket body 1410 and the frame body 1310.

[0074] For the locking structure 1500, the locking structure 1500 is connected between the bracket body 1410 and the frame body 1310, thereby locking and fixing the bracket body 1410 and the frame body 1310. Each bracket body 1410 is connected to the frame body 1310 by the locking structure 1500. The locking structure 1500 can restrict the movement of each bracket body 1410 relative to the frame body 1310 in all directions. Therefore, the locking structure 1500 can also be a welded structure formed by welding. Of course, the locking structure 1500 can also be a snap-fit ​​structure, etc. The structural form of the locking structure 1500 is not limited here. Any structural form that can limit and fix the bracket body 1410 to the frame body 1310 is a possible form of the locking structure 1500 in this application.

[0075] In this embodiment, the bracket body 1410 is connected to the frame body 1310 to support the battery device 1100. When the bracket body 1410 and the frame body 1310 are assembled, the first limiting structure 1320 and the second limiting structure 1420 can be inserted into each other, thereby realizing the positioning and initial limiting between each bracket body 1410 and the frame body 1310. After each bracket body 1410 is limited on the frame body 1310, the locking structure 1500 is used to lock the bracket body 1410 to the frame body 1310. By using a locking mechanism, the assembly and fastening sequence between the bracket body 1410 and the frame body 1310 is configured more rationally, thereby improving the ease of assembly between the bracket assembly 1400 and the frame assembly 1300 and increasing work efficiency. In addition, the connection between the first limiting structure 1320 and the second limiting structure 1420 can increase the connection and limiting position between the frame body 1310 and the bracket body 1410, and in conjunction with the locking structure 1500, it can further enhance the reliability of the connection between the frame body 1310 and the bracket body 1410.

[0076] In some embodiments, as shown in Figures 6-8 and 11, either the first limiting structure 1320 or the second limiting structure 1420 is a concave structure, and the other is a convex structure, with the convex structure and the concave structure interlocking.

[0077] Specifically, the concave structure can be a groove structure or a through-hole structure, and the convex structure can be a plate structure or a column structure. For example, if the first limiting structure 1320 is a concave structure, then the first limiting structure 1320 can be a groove structure opened on the frame body 1310. The groove structure can be a through groove, which is also a through-hole structure. Correspondingly, if the second limiting structure 1420 is a convex structure, then the convex structure can be a plug-in plate or plug-in post protruding outward on the surface of the bracket assembly 1400. When the frame body 1310 is connected to the bracket body 1410, the plug-in plate or plug-in post is inserted into the groove structure, thereby realizing the pre-positioning and limiting between the bracket body 1410 and the frame body 1310.

[0078] For example, multiple bracket bodies 1410 are arranged at intervals along the vertical direction, and the battery device 1100 abuts against the upper surface of each bracket body 1410. The protruding structure is located on the surface of the bracket body 1410 opposite to the frame body 1310 and extends outward toward the frame body 1310. The groove depth of the groove structure is parallel to the outward protrusion direction of the protruding structure. Thus, after the protruding structure and the groove structure are inserted, the bracket body 1410 is limited in the vertical direction relative to the frame body 1310. The bracket body 1410 can be positioned or hung on the frame body 1310.

[0079] Of course, the first limiting structure 1320 can also be a protruding structure, which protrudes outward and connects to the surface of the frame body 1310. Correspondingly, the second limiting structure 1420 is a concave structure, which is formed on the surface of the bracket body 1410.

[0080] Multiple first limiting structures 1320 and multiple second limiting structures 1420 can be provided respectively. A set is formed between a first limiting structure 1320 and a second limiting structure 1420, thereby enabling multiple insertion positions to be formed between the bracket body 1410 and the frame body 1310, improving the reliability of the connection between the bracket body 1410 and the frame body 1310.

[0081] In this embodiment, the first limiting structure 1320 and the second limiting structure 1420 adopt a protruding structure and a concave structure, respectively. The structure is simple, easy to manufacture, and helps to reduce processing difficulty and manufacturing cost.

[0082] In some embodiments, as shown in FIG6-11, the protruding structure includes a plug arm 1421 and a limiting arm 1422 connected to the plug arm 1421, wherein the plug arm 1421 and the limiting arm 1422 are arranged at an angle; the concave structure is a hole structure, wherein the plug arm 1421 is inserted into the hole structure, and the limiting arm 1422 is blocked outside the hole structure to prevent the plug arm 1421 from disengaging from the hole structure.

[0083] Specifically, the plug-in arm 1421 and the limiting arm 1422 can be connected in a fixed or detachable manner, such as by threaded connection or welding. The plug-in arm 1421 and the limiting arm 1422 can also be an integrally formed structure; for example, the protruding structure can be formed by bending the plug-in arm 1421 and the limiting arm 1422. The plug-in arm 1421 and the limiting arm 1422 can adopt a plate-like structure or a column-like (or rod-like) structure. The plug-in arm 1421 and the limiting arm 1422 can be set at an angle greater than 0° and less than 180°; for example, the plug-in arm 1421 and the limiting arm 1422 can be set at a 90° angle.

[0084] If the concave structure is a hole structure, when the protruding structure is inserted into the concave structure, the insertion arm 1421 is inserted into the hole structure. The limiting arm 1422 can be connected to the insertion end of the insertion arm 1421 to pass through the hole structure at the same time. Alternatively, the limiting arm 1422 can be connected to the insertion end of the insertion arm 1421 after the insertion arm 1421 passes through the hole structure. The limiting arm 1422 can abut against the surface outside the hole of the hole structure, thereby limiting the insertion arm 1421 and restricting the insertion arm 1421 in the axial direction along the hole structure. In this case, the protruding structure can be understood as a hook structure. The hook structure is hooked to the hole structure, thereby allowing the bracket body 1410 to be suspended on the frame body 1310.

[0085] In this embodiment, the protruding structure adopts a combination of a plug-in arm 1421 and a limiting arm 1422, so that while the plug-in arm 1421 is plugged into the hole structure, the limiting arm 1422 can also limit the plug-in plate, making the protruding structure less likely to come out of the hole structure and improving the reliability of the connection.

[0086] In some embodiments, as shown in Figures 2-8, the locking structure 1500 is riveted or threaded between the bracket body 1410 and the frame body 1310.

[0087] Specifically, the locking structure 1500 can employ a bolt assembly, which connects the bracket body 1410 and the frame body 1310 to achieve a threaded lock. Using a bolt assembly facilitates the installation and disassembly of the bracket body 1410 and the frame body 1310. Alternatively, the locking structure 1500 can employ a riveting assembly, whereby the bracket body 1410 is locked and secured to the frame body 1310 via the riveting assembly.

[0088] In this embodiment, the bracket body 1410 and the frame body 1310 are connected and fixed by threaded connection or riveting, which helps to improve the convenience of assembly.

[0089] In some embodiments, as shown in FIG2-5, each bracket body 1410 includes two bracket portions 1411 spaced apart from each other. The two bracket portions 1411 are disposed on the frame body 1310 and are used to jointly support the battery device 1100. Each bracket portion 1411 is connected to a second limiting structure 1420, and each bracket portion 1411 is connected to the frame body 1310 through a locking structure 1500.

[0090] Specifically, the bracket body 1410 can adopt a split structure. The bracket body 1410 includes two bracket parts 1411. The two bracket parts 1411 are spaced apart and can jointly support the battery device 1100. It is understood that when the battery device 1100 needs to be placed horizontally, the two bracket parts 1411 need to be arranged spaced apart in the horizontal direction. The two bracket parts 1411 each have a horizontal support surface, and the two support surfaces are coplanar.

[0091] Each bracket portion 1411 is connected to one or more second limiting structures 1420. The second limiting structures 1420 on the bracket portion 1411 are inserted and engaged with the first limiting structures 1320 on the frame body 1310, so that the bracket portion 1411 is inserted and limited on the frame body 1310. Each bracket portion 1411 and the frame body 1310 can be connected by a locking structure 1500.

[0092] In this embodiment, the bracket body 1410 adopts a structure in which two bracket parts 1411 are combined, which makes the assembly between the bracket body 1410 and the frame body 1310 more flexible and simplifies the overall structure of the frame body 1310, which helps to reduce the weight of the bracket body 1410.

[0093] In some embodiments, as shown in FIG2-7, both bracket portions 1411 are beam structures.

[0094] Specifically, each bracket part 1411 adopts a beam structure. The beam structure can be a hollow cylindrical wall structure or a plate structure. Two beam structures can be spaced apart and arranged in parallel. The sides of the beam structure can directly abut against the battery device 1100. The two beam structures can be supported on both sides of the bottom of the battery device 1100 respectively. The bottom middle position of the battery device 1100 can be suspended, which helps to simplify the structure of the bracket body 1410.

[0095] In this embodiment, the bracket 1411 adopts a beam structure to facilitate manufacturing, which helps to reduce manufacturing costs and the weight of the installation compartment 1200.

[0096] In some embodiments, referring to Figures 6 and 7, each bracket portion 1411 includes a first support arm 1412 and a second support arm 1413 connected to the first support arm 1412. The first support arm 1412 and the second support arm 1413 both extend along a first direction X and are arranged at an angle. A second limiting structure 1420 is connected to the first support arm 1412, and a locking structure 1500 is connected between the first support arm 1412 and the frame body 1310. The second support arm 1413 is used to support the battery device 1100.

[0097] Specifically, the first direction X is the length direction of the bracket portion 1411. The bracket portion 1411 includes two parts: a first support arm 1412 and a second support arm 1413. The first support arm 1412 and the second support arm 1413 can be fixedly or detachably connected. The first support arm 1412 and the second support arm 1413 can also be integrally formed. The first support arm 1412 and the second support arm 1413 are arranged at an angle by bending. The angle can be greater than 0° or less than 180°. For example, the first support arm 1412 and the second support arm 1413 are arranged perpendicularly.

[0098] The first support arm 1412 and the second support arm 1413 can both be plate-shaped. One or more second limiting structures 1420 are connected to the first support arm 1412. Therefore, the first support arm 1412 and the frame body 1310 are limited by the insertion of the first limiting structure 1320 and the second limiting structure 1420. The locking structure 1500 is connected between the first support arm 1412 and the frame body 1310. The battery device 1100 abuts against the second support arm 1413. The two second support arms 1413, which are spaced apart, are used to jointly support the battery device 1100. The two second support arms 1413 can be parallel and coplanar.

[0099] In this embodiment, the bracket 1411 adopts a combination of a first support arm 1412 and a second support arm 1413 connected at an angle. The battery device 1100 is supported by the second support arm 1413, making the overall structure of the bracket 1411 simple and easy to manufacture.

[0100] In some embodiments, as shown in Figures 6, 7 and 11, there are multiple second limiting structures 1420, which are spaced apart along the first direction X (i.e., the extension direction of the first support arm 1412); there are multiple first limiting structures 1320, and each first limiting structure 1320 is inserted into and cooperates with each second limiting structure 1420.

[0101] Since the first support arm 1412 has a relatively long extension length, multiple second limiting structures 1420 are connected and arranged at intervals along the length direction of the first support arm 1412. Correspondingly, the same number of first limiting structures 1320 are arranged on the frame body 1310. One second limiting structure 1420 is inserted and engaged with one first limiting structure 1320, so that multiple insertion and limiting positions are formed between the first support arm 1412 and the frame body 1310, thereby improving the reliability of the connection between the first support arm 1412 and the frame body 1310.

[0102] In this embodiment, by setting multiple second limiting structures 1420 and first limiting structures 1320 that are plugged into and cooperate with them, multiple plugging connection positions are formed between the first support arm 1412 and the frame body 1310, thereby improving the reliability of the connection between the first support arm 1412 and the frame body 1310.

[0103] In some embodiments, referring to Figures 2 and 3, the frame body 1310 includes a plurality of frame portions 1311, which are arranged sequentially at intervals along the second direction Y. Each frame portion 1311 is connected to a first limiting structure 1320. One or more bracket bodies 1410 are provided between any two adjacent frame portions 1311. The two ends of the bracket body 1410 opposite to the frame portions 1311 are respectively connected to the second limiting structure 1420. Each frame portion 1311 is connected to the bracket body 1410 through a locking structure 1500.

[0104] For the frame body 1310, the frame body 1310 should meet the support strength and rigidity requirements for the battery device 1100. While meeting the rigidity and strength requirements, the weight of the frame body 1310 should be as lightweight as possible to achieve a lightweight installation compartment 1200 and energy storage device 1000. Therefore, in this embodiment, the frame body 1310 includes a plurality of frame portions 1311, which are arranged sequentially at intervals along the second direction Y. Any two adjacent frame portions 1311 are arranged opposite each other at intervals. A space 1600 for accommodating the battery device 1100 is formed between the frame portions 1311. The bracket body 1410 is located in the space 1600 and is connected to two adjacent and spaced-apart frame portions 1311 respectively. One or more bracket bodies 1410 can be arranged between any two frame portions 1311. Multiple bracket bodies 1410 can be spaced apart in the third direction Z. The third direction Z can be perpendicular to the second direction Y, so that the battery device 1100 can be accommodated in the space above the bracket body 1410.

[0105] For example, if the second direction Y is horizontal and the third direction Z is perpendicular to the second direction Y, then the third direction Z should be understood as a vertical direction. The third direction Z should be understood as the length direction or extension direction of the frame body 1310. The first direction X should be understood as a horizontal direction that is perpendicular to both the second direction Y and the third direction Z.

[0106] It can be seen that each frame portion 1311 is connected to a first limiting structure 1320. It should be noted that among the multiple frame portions 1311, the frame portions 1311 located at the first end and the last end along the second direction Y are connected to a first limiting structure 1320 on only one side. The frame portions 1311 located between the first end and the last end are connected to multiple first limiting structures 1320 on both sides. Correspondingly, the bracket body 1410 is connected to two second limiting structures 1420, and one second limiting structure 1420 is opposite to and plugged into one first limiting structure 1320. For example, the bracket body 1410 has two connecting ends, and each connecting end is connected to a second limiting structure 1420. Each connecting end is opposite to the corresponding frame portion 1311, so that the second limiting structure 1420 is plugged into the corresponding first limiting structure 1320.

[0107] Multiple locking structures 1500 are provided. The two connecting ends of a bracket body 1410 are locked and fixed to the frame part 1311 by one or more locking structures 1500.

[0108] In this embodiment, multiple bracket bodies 1410 are connected between two adjacent frame portions 1311. The two sides of the frame portion 1311 located between the first and last ends can be connected to one end of the bracket body 1410, which helps to simplify the structure of the frame body 1310, reduce the number of beam portions, and reduce the weight of the installation chamber 1200.

[0109] In some embodiments, referring to Figures 1 and 3, the installation compartment 1200 includes a plurality of compartment sections 1700, each compartment section 1700 including a frame assembly 1300, a bracket assembly 1400 and a locking structure 1500, the plurality of compartment sections 1700 being arranged sequentially along the second direction Y; each frame body 1310 includes two spaced-apart frame sections 1311, each frame section 1311 being connected to a first limiting structure 1320, the two ends of the bracket body 1410 opposite to the two frame sections 1311 being respectively connected to the second limiting structure 1420, and each frame section 1311 being connected to the bracket body 1410 through the locking structure 1500.

[0110] Specifically, a compartment 1700 may be an installation module of the installation compartment 1200. Each compartment 1700 includes the frame assembly 1300, bracket assembly 1400 and locking structure 1500 as described in the above example. Each compartment 1700 may accommodate one or more battery devices 1100, and a bracket assembly 1400 may support at least one battery device 1100.

[0111] The installation compartment 1200 may include multiple compartment sections 1700 in the form of modules. The multiple compartment sections 1700 may be arranged sequentially along the second direction Y. The second direction Y may be a direction perpendicular to the first direction X. For example, when the installation compartment 1200 is placed horizontally, the first direction X is a vertical direction and the second direction Y may be a horizontal direction.

[0112] For the frame body 1310 in each compartment 1700, the frame body 1310 includes two frame sections 1311, which are spaced apart. The space 1600 between the two frame sections 1311 is the space for accommodating the battery device 1100. The bracket body 1410 is located in the space 1600 and is connected to the two frame sections 1311 respectively. For the compartment 1700, the compartment 1700 should meet the support strength and rigidity requirements for the battery device 1100. While meeting the rigidity and strength requirements, the weight of the compartment 1700 should be as light as possible so that the installation compartment 1200 and the energy storage device 1000 can be lightweight.

[0113] It is known that each frame portion 1311 is connected to a first limiting structure 1320. Correspondingly, the bracket body 1410 is connected to two second limiting structures 1420. The two second limiting structures 1420 are located at the ends of the bracket body 1410 opposite to the two adjacent frame portions 1311. Each second limiting structure 1420 is opposite to and plugged into a first limiting structure 1320. For example, the bracket body 1410 has two connecting ends, each of which is connected to a second limiting structure 1420. The two connecting ends are opposite to the two corresponding frame portions 1311, so that the second limiting structure 1420 is plugged into the corresponding first limiting structure 1320.

[0114] Multiple locking structures 1500 are provided, and a frame part 1311 and a bracket body 1410 are locked and fixed by at least one locking structure 1500.

[0115] In this embodiment, the installation compartment 1200 is formed by assembling multiple modular compartment parts 1700, which allows the installation compartment 1200 to be assembled in a modular manner, thereby improving the flexibility and convenience of assembling the overall structure of the installation compartment 1200; the frame body 1310 adopts two frame parts 1311 arranged at intervals, which helps to simplify the structure of the frame body 1310 and improve the flexibility and ease of assembly of the frame body 1310 structure.

[0116] In some embodiments, as shown in Figures 2, 3 and 9-11, each frame portion 1311 includes a plurality of spaced-apart support columns 1312, at least one support column 1312 in each frame portion 1311 is connected to a first limiting structure 1320, and at least one support column 1312 in each frame portion 1311 is connected to the bracket body 1410 through a locking structure 1500.

[0117] Specifically, each frame section 1311 adopts a method of arranging multiple support columns 1312 at intervals. The multiple support columns 1312 may or may not be connected. For example, adjacent support columns 1312 can be connected and fixed by stiffening plates, thereby improving the structural strength and rigidity between the frame sections 1311.

[0118] The support column 1312 can be a hollow cylindrical structure or a solid column structure. For example, the support column 1312 can be made of hollow steel. Each frame part 1311 can include 2-6 support columns 1312. At least one of the support columns 1312 in a frame part 1311 is connected to a first limiting structure 1320. For example, each frame part 1311 includes 3 support columns 1312 arranged at intervals. The three support columns 1312 in two frame parts 1311 are arranged opposite to each other. The first limiting structure 1320 can be connected to each of the three support columns 1312. The two connecting ends of the bracket body 1410 are respectively connected to three second limiting structures 1420, so that one first limiting structure 1320 and one second limiting structure 1420 are inserted and matched.

[0119] For the locking structure 1500, at least one support column 1312 in a frame portion 1311 is locked and fixed to the bracket body 1410 through the locking structure 1500. For example, each support column 1312 connected to the first limiting structure 1320 is locked and fixed to the bracket body 1410 through the locking structure 1500.

[0120] In this embodiment, the frame 1311 adopts a combination of multiple support columns 1312 at intervals, which helps to simplify the structure of the frame 1311 and reduce the overall weight of the installation compartment 1200.

[0121] In some embodiments, as shown in Figures 2-5 and 9-11, the support column 1312 extends along the third direction Z, and a plurality of bracket bodies 1410 are spaced apart along the third direction Z. Each bracket body 1410 is connected to a first limiting structure 1320, and the third direction Z is perpendicular to the second direction Y.

[0122] Taking the third direction Z as the vertical direction as an example, the length direction or extension direction of the support column 1312 is along the third direction Z. Multiple support columns 1312 in a frame part 1311 are spaced apart in a direction perpendicular to the third direction Z. The range perpendicular to the third direction Z is the second direction Y. Each support column 1312 in any two adjacent frame parts 1311 is arranged opposite to each other, and a gap space 1600 is formed between two adjacent frame parts 1311.

[0123] Multiple bracket bodies 1410 are spaced apart in the third direction Z, thereby forming an accommodating space between two adjacent bracket bodies 1410. It can be seen that the multiple bracket bodies 1410 are connected to the support column 1312, thereby forming multiple accommodating spaces in the third direction Z of the installation compartment 1200. The accommodating space is used to accommodate the battery device 1100, and the battery device 1100 abuts against the upper surface of the bracket body 1410.

[0124] One or more first limiting structures 1320 are connected to the two connecting ends of each bracket body 1410. The first limiting structure 1320 is inserted into the second limiting structure 1420 on the support column 1312, thereby enabling the bracket body 1410 and the support column 1312 to be inserted into and limited.

[0125] In this embodiment, multiple bracket bodies 1410 are provided, each of which can support the battery device 1100, thereby enabling the installation compartment 1200 to accommodate more battery devices 1100 and increase the energy storage capacity of the energy storage device 1000.

[0126] In some embodiments, referring to Figures 2, 3, and 9-11, the frame body 1310 includes a plurality of inter-frame portions 1311, which are arranged sequentially at intervals along the second direction Y. Each frame portion 1311 includes a plurality of spaced-apart support columns 1312, and at least one support column 1312 in each frame portion 1311 is connected to a first limiting structure 1320. One bracket portion 1411 in the bracket body 1410 is connected to at least one support column 1312 in one frame portion 1311 through a locking structure 1500. Another bracket portion 1411 in the bracket body 1410 is connected to at least one support column 1312 in an adjacent frame portion 1311 through a locking structure 1500.

[0127] For example, the frame body 1310 includes a plurality of frame sections 1311 arranged sequentially at intervals along a second direction Y, where the second direction Y is horizontal. An interval space 1600 is formed between two adjacent frame sections 1311. Each frame section 1311 includes three support columns 1312. The support columns 1312 adopt a hollow cylindrical wall structure and extend vertically. Each support column 1312 is connected to a plurality of first limiting structures 1320 along the vertical direction. Multiple bracket bodies 1410 are provided, and the multiple bracket bodies 1410 are spaced apart in the vertical direction (or the third direction Z). Each bracket body 1410 includes two bracket parts 1411, and each bracket part 1411 is connected to three second limiting structures 1420. A first limiting structure 1320 is opposite to and inserted into a second limiting structure 1420, so that a bracket part 1411 can be inserted into and limited by the three support columns 1312 in a frame part 1311. Each bracket portion 1411 is locked and fixed to the three support columns 1312 in each frame portion 1311 by a locking structure 1500. The number of first limiting structures 1320 (or second limiting structures 1420) can be the same as the number of locking structures 1500, so that the insertion and limiting position between the bracket portion 1411 and the support column 1312 is also locked and fixed by the locking structure 1500, thereby improving the connection reliability between the bracket portion 1411 and the support column 1312. It should be noted that two bracket portions 1411 in a bracket body 1410 are respectively connected to two adjacent frame portions 1311, and two bracket portions 1411 in a bracket body 1410 are respectively connected to one or more support columns 1312 in the frame portion 1311 by the locking structure 1500.

[0128] In this embodiment, the bracket portion 1411 and the support column 1312 are connected and limited by the insertion between the first limiting structure 1320 and the second limiting structure 1420, and are also locked and fixed by the locking structure 1500. This helps to improve the reliability and convenience of the connection between the bracket portion 1411 and the support column 1312. In addition, the insertion and cooperation of the first limiting structure 1320 and the second limiting structure 1420 can also play a role in the early positioning of the installation of the locking structure 1500, improve the convenience of the assembly of the locking structure 1500, and help to improve the assembly efficiency.

[0129] In some embodiments, the energy storage device 1000 can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems, etc. The energy storage device 1000 can store electrical energy as needed and output electrical energy when appropriate. For example, the energy storage device 1000 can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. The energy storage system provided in this application embodiment can be any power system that requires the use of the energy storage device 1000.

[0130] In some embodiments, as shown in FIG1, the energy storage device 1000 further includes a housing 1800, an assembly space is formed inside the housing 1800, and an installation compartment 1200 is housed in the assembly space. The housing 1800 protects the installation compartment 1200 from the outside of the installation compartment 1200.

[0131] In some embodiments, the energy storage device 1000 is an energy storage container or an energy storage cabinet.

[0132] In some embodiments, the energy storage device 1000 may include a cabinet and one or more battery clusters, the battery clusters being housed within the cabinet.

[0133] In some embodiments, the energy storage device 1000 may include modules such as a thermal management module, a main control module, a central control module, a power distribution module, and a fire protection module.

[0134] As an example, the thermal management module may include a liquid cooling unit that supplies coolant to each battery device 1100 via piping to regulate the temperature of the individual battery cells.

[0135] As an example, the main control module can serve as the battery management unit for the battery cluster, used to monitor and manage the battery cluster. The main control module can monitor information such as the current, voltage, power, or temperature of the battery cluster. For instance, it can control the charging and discharging current and voltage of the battery cluster. The main control module includes modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0136] As an example, the central control module can serve as the battery management unit of the energy storage device 1000, used for monitoring and managing the energy storage device 1000. The central control module can monitor information such as the current, voltage, power, state of charge, or temperature of the energy storage device 1000. For example, it can control the charging and discharging current and voltage of the energy storage device 1000. As an example, the central control module includes modules such as an insulation monitoring module (IMM), a master battery management unit (MBMU), an Ethernet (ETH) module, and a fiber optic conversion module.

[0137] As an example, the fire protection module includes a control panel, detectors, alarm devices, etc., used to detect, alarm, or extinguish fires in the energy storage system.

[0138] As an example, the power distribution module can be used to distribute power to the modules in the energy storage device 1000 that require electricity.

[0139] In one specific embodiment, referring to Figures 1, 2, and 4-11, the energy storage device 1000 includes a battery device 1100 and a mounting compartment 1200. The mounting compartment 1200 includes a frame assembly 1300, a bracket assembly 1400, and a locking structure 1500. The frame assembly 1300 includes a frame body 1310 and a first limiting structure 1320 connected to the frame body 1310. Multiple bracket assemblies 1400 are provided, each including a bracket body 1410 and a second limiting structure 1420 connected to the bracket body 1410. The bracket body 1410 is disposed on the frame body 1310 and used to support the battery device 110. 0.
