Description

Stacked battery clusters Technical Field

[0001] This utility model relates to the field of energy storage system technology, and in particular to a stacked battery cluster. Background Technology

[0002] A battery cluster is a battery pack design that stacks multiple battery cells vertically or horizontally to form a compact structure, making the battery pack suitable for applications with limited space. Considering issues such as condensation, corrosion, and space utilization, battery packs are generally not placed directly on the ground. Instead, multiple batteries are placed in a battery rack to form a battery cluster for use as a whole. Current battery racks are generally welded monolithic frame structures, which are large and heavy, difficult to transport, and require a certain amount of installation space. Furthermore, their large size leads to high transportation costs and inconvenient installation. Summary of the Invention

[0003] The main purpose of this invention is to propose a stacked battery cluster, which aims to make the stacked battery cluster easy to install and reduce transportation costs.

[0004] To achieve the above objectives, the present invention proposes a stacked battery cluster, comprising: a base, battery components, and mounting components; the battery components are stacked on the base, and the battery components are stacked in multiple layers along a first direction, each battery component including a battery and a support component disposed on the outer periphery of the battery, and the support components of adjacent battery components are interconnected; the mounting components are disposed on the side of the battery component away from the base.

[0005] In one embodiment, two sets of support components are arranged opposite each other along a second direction, and the two sets of support components are detachably installed on the two side walls of the battery, wherein the second direction intersects the first direction.

[0006] In one embodiment, the support assembly includes at least two support members spaced apart along a third direction. Each support member has an interconnected column and a connecting plate. The column is located on the side of the connecting plate opposite to the battery. The support member is detachably mounted to the battery via the connecting plate. The third direction intersects with the first direction and the second direction.

[0007] In one embodiment, the column is provided with a first limiting post at one end near the mounting member, and a first limiting hole is provided at one end of the column near the base. When the battery assembly is stacked along a first direction, the first limiting post on the lower support member is inserted into the first limiting hole on the upper support member.

[0008] In one embodiment, the connecting plate is detachably mounted to the side wall of the battery via fasteners, and the column has a clearance hole corresponding to the position of the fasteners, the clearance hole extending through the column in a second direction.

[0009] In one embodiment, the connecting plate includes a first piece and a second piece, the second piece extending from one end of the first piece near the mounting member toward the side near the battery; one side of the first piece abuts against the side wall of the battery by a fastener, the column is mounted on the side of the first piece away from the battery, and the second piece abuts against the upper wall of the battery.

[0010] In one embodiment, the stacked battery cluster further includes a first fixing plate for fixing two adjacent support components together.

[0011] In one embodiment, the first fixing plate has connecting portions at both ends. The connecting portions have a first connecting hole and a second connecting hole for fasteners to pass through. The first connecting hole and the second connecting hole are spaced apart along a first direction. The fastener is connected to the lower support component of two adjacent support components through the first connecting hole, and the fastener is connected to the upper support component of two adjacent support components through the second connecting hole.

[0012] In one embodiment, the base includes a body, a support leg, a second limiting post, and a second fixing plate.

[0013] In one embodiment, the stacked battery cluster further includes a control system electrically connected to each of the battery components. The control system is mounted on the side of the mounting member away from the battery components. A second limiting hole is formed on the side of the mounting member close to the battery components, and the mounting member is limited to the battery components through the second limiting hole.

[0014] This invention employs a stacked battery cluster comprising a base, battery components, and mounting components. Multiple battery components are stacked on the base along a first direction. Mounting components cover the side of the battery components away from the base. Each battery component includes a battery and a support component located around the battery. Adjacent support components are interconnected. This allows the battery cluster to be disassembled into multiple parts for transport.

[0025] This utility model proposes a stacked battery cluster 100.

[0026] Please refer to Figures 1 to 3. In one embodiment of this utility model, the stacked battery cluster 100 includes: a base 1, a battery assembly 2, and a mounting member 3; the battery assembly 2 is stacked on the base 1, and the battery assembly 2 is stacked in multiple layers along a first direction. Each battery assembly 2 includes a battery 21 and a support assembly disposed on the outer periphery of the battery 21. The support assemblies of adjacent layers of battery assembly 2 are connected to each other; the mounting member 3 is disposed on the side of the battery assembly 2 away from the base 1.

[0027] In this embodiment, battery components 2 are stacked on the base 1. The number of stacked battery components 2 can be increased or decreased according to actual application needs. Compared to a fixed-size bracket, the volume of the stacked battery cluster 100 can be minimized while ensuring usability, thus minimizing space occupation. Mounting components 3 are installed on the top of the uppermost battery component 2. Mounting components 3 are used to fix and install components other than the battery components 2, such as the control system and operation panel, to ensure the usability of the stacked battery cluster 100. During transportation, the stacked battery cluster 100 can be disassembled into multiple components through a detachable structure. These components can be arranged into various shapes, allowing for reasonable space allocation based on the size of the transport vehicle during loading and transportation, thereby increasing transportation efficiency and reducing transportation costs. After transportation to the predetermined location, the multiple component structures of the stacked battery cluster 100 can be quickly assembled and put into use.

[0028] The technical solution of this utility model adopts a stacked battery cluster 100 by setting a base 1, a battery assembly 2, and a mounting component 3. The battery assembly 2 is stacked in multiple layers on the base 1 along a first direction. The mounting component 3 covers the side of the battery assembly 2 away from the base 1. The battery assembly 2 includes a battery 21 and a support assembly disposed on the periphery of the battery 21. Adjacent support assemblies are interconnected. This allows the battery cluster to be disassembled into multiple parts for transportation. Each disassembled part occupies a small space, reducing the space occupied during transportation. Moreover, the position of each component is not restricted during transportation, making it easy to plan the accommodation space of the transportation device, thereby reducing the transportation cost of the stacked battery cluster 100. When needed, multiple batteries 21 can be quickly stacked and assembled using the support assembly, and can be quickly assembled with the base 1 and the mounting component 3 to form the stacked battery cluster 100 for use, thus making the stacked battery cluster 100 easy to install.

[0029] In one embodiment, two sets of support components are arranged opposite each other along a second direction. These two sets of support components are detachably mounted on the side walls of the battery 21, with the second direction intersecting the first direction. The support components support the battery 21 from opposite sides, thereby balancing the forces on the battery 21 and making the support structure of the battery assembly 2 more stable. The two support components are arranged opposite each other, with the battery body acting as a crossbeam between the two support components. This allows the support components to fit with the outer wall of the battery body, minimizing the volume occupied by the battery assembly 2. Furthermore, the spacing between the two sets of support components can be adjusted to accommodate the actual short-length dimensions of the battery 21, thus adapting to more battery models. Additionally, the structure where the separate support components intersect and are integrated into a single unit is more flexible and occupies less space.

[0030] In one embodiment, the support assembly includes at least two support members 22 spaced apart along a third direction. Each support member 22 has an interconnected column 221 and a connecting plate 222. The column 221 is located on the side of the connecting plate 222 facing away from the battery 21. The support member 22 is detachably mounted to the battery 21 via the connecting plate 222. The third direction intersects with the first and second directions. Each support assembly includes at least two support members 22 spaced apart along a third direction, making the support members 22 provide more stable support for the battery 21. The support members 22 can be increased or decreased according to the actual mass and volume of the battery 21. The support members 22 support the structure above via the column 221 and are mounted to the side wall of the battery 21 via the connecting plate 222.

[0031] In one embodiment, the end of the column 221 near the mounting member 3 is provided with a first limiting post 221a, and the end of the column 221 near the base 1 is provided with a first limiting hole 221b. When the battery assembly 2 is stacked along the first direction, the first limiting post 221a on the lower support member 22 is inserted into the first limiting hole 221b on the upper support member 22. By inserting the first limiting post 221a into the first limiting hole 221b, the cooperation between the first limiting post 221a and the first limiting hole 221b can limit the two adjacent battery assemblies 2. This ensures that the multi-layer battery assemblies 2 are properly positioned, avoids skewing of the multi-layer structure, makes the structure more stable, and also facilitates the alignment and installation between adjacent battery assemblies 2.

[0032] In one embodiment, the connecting plate 222 is detachably mounted to the side wall of the battery 21 via fasteners. A clearance hole 221c is provided on the column 221 at the position corresponding to the fastener, and the clearance hole 221c extends through the column 221 in a second direction. The connecting plate 222 and the side wall of the battery 21 are detachably connected via fasteners, thereby facilitating the disassembly and assembly of the stacked battery cluster 100. The clearance hole 221c on the column 221 at the position corresponding to the fastener, extending through the column 221, allows installers to screw the fasteners into the corresponding positions through the clearance hole 221c and facilitates inspection of the fastener's tightness.

[0033] In one embodiment, the connecting plate 222 includes a first piece 222a and a second piece 222b. The second piece 222b extends from the end of the first piece 222a near the mounting member 3 toward the side near the battery 21. One side of the first piece 222a abuts against the side wall of the battery 21 by fasteners. The column 221 is installed on the side of the first piece 222a away from the battery 21. The second piece 222b abuts against the upper wall of the battery 21. The connecting plate 222 includes a first piece 222a and a second piece 222b. The first piece 222a supports and installs the column 221. The second piece 222b is used as a pad between two adjacent battery layers 21 to prevent relative friction between the two adjacent battery layers 21 and cause scratches, while also limiting the position of the battery 21 in the height direction.

[0034] In one embodiment, the stacked battery cluster 100 further includes a first fixing plate 4, which is used to fix two adjacent support components together. After the first limiting post 221a in the lower battery component 2 is inserted into the first limiting hole 221b in the upper battery component 2, the two adjacent support components are simultaneously connected by the first fixing plate 4 to fix the two adjacent support components together, thereby ensuring the structural stability of the stacked battery cluster 100 and preventing the two adjacent battery components 2 from separating.

[0035] In one embodiment, the first fixing plate 4 has connecting portions at both ends. The connecting portions have a first connecting hole 41 and a second connecting hole 42 for fasteners to pass through. The first connecting hole 41 and the second connecting hole 42 are spaced apart along a first direction. The fastener connects to the lower support component of two adjacent support components through the first connecting hole 41, and to the upper support component of two adjacent support components through the second connecting hole 42. The first connecting hole 41 and the second connecting hole 42 are used to insert the fastener. The fastener connects to the lower support component through the first connecting hole 41 and to the upper support component through the second connecting hole, thereby being fixedly connected to both adjacent support components.

[0036] In one embodiment, the base 1 includes a body 11, a support leg 12, a second limiting post 13, and a second fixing plate 14. The support leg 12 is located on the side of the body 11 away from the battery 21, and the second limiting post 13 is located on the side of the body 11 close to the battery 21. The second limiting post 13 is used to limit the battery assembly 2, and the second fixing plate 14 is used to detachably connect the battery assembly 2 to the body 11. The body 11 is used to support the multi-layer battery assembly 2 structure above, and the support leg 12 is used to suspend the body 11 above the ground so that the battery assembly 2 is at a certain height from the ground. The second limiting post 13 has the same size and shape as the first limiting post 221a so that the second limiting post 13 can be inserted into the first limiting block of the bottom battery assembly 2. The second fixing plate 14 is used to limit and fix the bottom battery assembly 2 to the body 11 to prevent the battery assembly 2 from detaching from the base 1.

[0037] In one embodiment, the stacked battery cluster 100 further includes a control system electrically connected to each battery component 2. The control system is mounted on the side of the mounting member 3 facing away from the battery component 2. A second limiting hole is provided on the side of the mounting member 3 closest to the battery component 2, and the mounting member 3 is limited to the battery component 2 through the second limiting hole. The control system is used to control the battery component 2 to charge and discharge in a preset manner through electrical signals. The control system also includes an operation panel electrically connected to it. The operation panel is mounted on top of the stacked battery cluster 100 through the mounting member 3, thereby facilitating the operation of the stacked battery cluster 100 by the operator.

[0038] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
