Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and in particular, to a container power supply and electrical equipment. Background Technology

[0002] With the popularization of new energy technologies, new energy batteries are widely used in various equipment. For equipment with high power demand, such as ships, multiple battery packs are usually integrated into a large enclosure using a battery pack mounting bracket with a specific structure. However, due to the unreasonable structural design of current battery pack mounting brackets, the space utilization rate inside the enclosure is often low, and there may even be insufficient maintenance space inside the enclosure, making it impossible to complete the inspection or maintenance of the battery packs inside the enclosure. Utility Model Content

[0003] In view of this, the present disclosure provides a container power supply and electrical equipment, which aims to at least address the problem of insufficient maintenance space inside the container power supply caused by an unreasonable design of the battery pack mounting structure.

[0004] On one hand, this disclosure provides a containerized power supply, which includes a container body, multiple battery packs, a cooling assembly, and a battery pack mounting bracket. The battery pack mounting bracket is disposed inside the container body. The battery pack mounting bracket includes multiple supports, each of which includes multiple longitudinal beams and multiple mounting units. The multiple mounting units are connected to the multiple longitudinal beams. The multiple longitudinal beams extend along the height direction of the container body, and the multiple mounting units are stacked along the height direction of the longitudinal beams. Each mounting unit has an installation space, and a single battery pack is fixedly installed in the installation space. In the width direction of the container body, one end of the mounting unit protrudes from the multiple longitudinal beams. The cooling assembly is connected to the multiple longitudinal beams, and the cooling assembly is located in the space between the protruding end of the mounting unit and the multiple longitudinal beams.

[0005] On the other hand, this disclosure also provides an electrical appliance that includes the container power supply described above.

[0006] According to the container power supply and electrical equipment disclosed herein, by protruding one end of the mounting unit from a portion of the longitudinal beams in the width direction of the container, a receiving space is formed between the end of the mounting unit and the portion of the longitudinal beams, and the cooling assembly is installed in this receiving space. In this way, the cooling assembly does not occupy additional space in the width direction of the container, thus allowing for more maintenance space inside the container. Attached Figure Description

Detailed Implementation

[0028] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0029] In related technologies, for equipment with high power demands, such as ships, multiple battery packs are typically integrated into a large container using a battery pack mounting bracket with a specific structure to achieve a containerized power supply with a large capacity. To ensure the safety of the containerized power supply during operation, appropriate cooling components and fire-fighting facilities must be installed within the container. However, current battery pack mounting brackets, due to their structural limitations, cannot be arranged "incompatiblely" with cooling components. That is, the cooling components will occupy additional space in the width and / or length directions of the container, on top of the space occupied by the battery pack mounting bracket. Thus, the space in the width and / or length directions of the container is simultaneously occupied by the battery pack mounting bracket and the cooling components, resulting in limited remaining space in these directions, which cannot meet the dimensional requirements for maintenance space.

[0030] In one existing technology, the excessive space occupied in the width direction of the container prevents the provision of maintenance space inside. This makes routine maintenance and inspection of the battery packs impossible within the container. When maintenance or repair of the battery packs is required, the entire battery pack mounting bracket must be removed from the container to inspect and repair each individual battery pack on the bracket. This not only wastes a significant amount of time but also makes it difficult to guarantee the safety performance of the containerized power supply during use.

[0031] The inventors discovered that the above problems stemmed from the unreasonable structural design of the battery pack mounting bracket, which prevented the battery pack mounting bracket from being "compatible" with the cooling components. To solve this problem, the inventors made numerous attempts and ultimately creatively proposed the following technical solution: By protruding one end of the mounting unit beyond a portion of the longitudinal beams along the width of the enclosure, a receiving space is formed between the end of the mounting unit and the portion of the longitudinal beams. The cooling components are then installed within this receiving space. In this way, the cooling components no longer occupy additional space along the width of the enclosure, thus allowing for more maintenance space inside the enclosure, enabling personnel to perform inspection and maintenance work on the battery pack from within the enclosure.

[0032] The battery pack described in this disclosure includes a battery pack composed of multiple battery cells connected in series and / or in parallel to form a battery management system (BMS), a thermal management system, an electrical connection system (high-voltage / low-voltage connectors, wiring harnesses, etc.), structural components (casing, brackets, etc.), and protective components, etc., and the above components are placed in the battery box and sealed with a cover plate to form a complete functional unit that can directly output electrical energy.

[0033] The battery enclosure described in this disclosure refers to a closed or semi-closed structure made of metals such as steel plates or aluminum alloys, plastics, or lightweight materials such as glass fiber reinforced composites or carbon fiber reinforced composites. It serves as the physical carrier of the battery pack, and its design and manufacturing must meet the safety, reliability, and functionality requirements of the battery pack under different usage scenarios. The enclosure provides installation space for the battery pack, BMS, cooling system, electrical connection components, etc., and through a reasonable structural design, fixes these components within the enclosure, ensuring they maintain a relatively stable position during battery pack operation and preventing damage or loosening of connections due to vibration, impact, or other factors.

[0034] A battery casing typically consists of an upper casing and a lower casing. The lower casing usually has four side panels and a bottom plate. The four side panels can be integrally formed with the bottom plate or formed separately and fixedly connected. The casing shape can be cylindrical, cuboid, cube, etc.

[0035] The aforementioned battery cell refers to a battery that can store chemical energy and controllably convert it into electrical energy. In recyclable batteries, the active materials can be reactivated by charging after discharge, allowing for continued use. A battery cell typically includes a casing and a battery cell housed within the casing.

[0036] <Example Containerized Power Supply> This disclosure provides a container power supply, which includes a container body 200, multiple battery packs 400, and a battery pack mounting frame 100. The battery pack mounting frame 100 is disposed inside the container body 200. The battery pack mounting frame 100 includes multiple supports, each of which includes multiple longitudinal beams 10 and multiple mounting units 20. The multiple mounting units 20 are connected to the multiple longitudinal beams 10. The multiple longitudinal beams 10 extend along the height direction of the container body 200, and the multiple mounting units 20 are stacked along the height direction of the longitudinal beams 10. Each mounting unit 20 has an installation space, and a single battery pack 400 is fixedly installed in the installation space. In the width direction of the container body 200, one end of the mounting unit 20 protrudes from the multiple longitudinal beams. A cooling component is connected to the multiple longitudinal beams 10, and the cooling component is located in the space between the end of the mounting unit 20 protruding from the multiple longitudinal beams 10 and the multiple longitudinal beams 10.

[0037] For ease of understanding, the containerized power supply disclosed herein will be described in detail below with reference to the accompanying drawings. In the drawings, the X-axis can represent, for example, the length direction of the containerized power supply, i.e., the length direction of the container; the Y-axis can represent, for example, the width direction of the containerized power supply, i.e., the width direction of the container; and the Z-axis can represent, for example, the height direction of the containerized power supply, i.e., the height direction of the container.

[0038] See Figures 1 to 16 The containerized power supply includes multiple battery packs 400, battery pack mounting brackets 100, and a container body 200. The battery packs 400 are respectively fixedly mounted on the battery pack mounting brackets 100, which are fixed inside the container body 200. One or more battery pack mounting brackets 100 can be installed inside the container body 200. The number of battery pack mounting brackets 100 can be determined according to the power consumption of the electrical equipment. For example, when the power consumption of the electrical equipment is high, the number of battery pack mounting brackets 100 can be appropriately increased; when the power consumption of the electrical equipment is low, the number of battery pack mounting brackets 100 can be appropriately decreased.

[0039] See also Figures 1 to 4Each battery pack mounting bracket 100 includes multiple supports, which can be arranged along the length of the housing 200, with adjacent supports connected to each other. Each bracket includes multiple mounting units 20, which are arranged along the height of the housing 200 on the bracket. Each mounting unit 20 can, for example, mount one battery pack 400, meaning each bracket can accommodate multiple battery packs 400, and the multiple battery packs 400 are stacked on each bracket along the height of the housing 200. In this way, the multiple battery packs 400 are independent of each other, which not only facilitates heat dissipation of the battery packs 400, but also allows for independent inspection and maintenance of individual battery packs 400.

[0040] The structure of the bracket will be described in detail below using the battery pack holder 100 that accommodates the square battery pack 400 as an example. Unless otherwise specified, the battery pack holder 100 is considered to be used to accommodate the square battery pack 400.

[0041] See Figures 6 to 9 The figure shows the structure of a single bracket from various perspectives. As shown, each bracket includes multiple longitudinal beams 10 and multiple mounting units 20. The longitudinal beams 10 are parallel to each other and extend along the height direction of the housing 200. The mounting unit 20 may, for example, have a square receiving space adapted to a square battery pack 400. The number of longitudinal beams 10 may be, for example, four, and the four longitudinal beams 10 may be respectively positioned at the four corners of the mounting unit 20; that is, the mounting unit 20 is located within the space defined by the four longitudinal beams 10. In this way, the four longitudinal beams 10 can provide support to the mounting unit 20 from the four corner positions, thereby improving the stability of the mounting unit 20.

[0042] like Figure 6 As shown, each mounting unit 20 may include, for example, two first support beams 21 and three second support beams 22. The two first support beams 21 are parallel to each other and extend along the length of the housing 200, and each first support beam 21 is connected to its corresponding longitudinal beam 10 via its end. The three second support beams 22 are parallel to each other and extend along the width of the housing 200, with two second support beams 22 located on either side of the mounting unit 20 along its length, and the third second support beam 22 located at the middle position along the length of the mounting unit 20. Each of the three second support beams 22 is connected to two first support beams 21. Preferably, the two second support beams 22 located on either side of the mounting unit 20 may also be connected to their corresponding longitudinal beams 10 to improve the connection strength between the two second support beams 22.

[0043] When the square battery pack 400 is placed in the mounting unit 20, the three second support beams 22 can provide support for the battery pack 400 from the periphery and center of its bottom surface, respectively, improving the stability of the battery pack 400 in the mounting unit 20. This avoids the situation where the battery pack 400 is prone to significant vibration when supported only from the periphery of its bottom surface.

[0044] Furthermore, such as Figure 6 and Figure 7 As shown, in the width direction of the housing 200, one end of each of the three second support beams 22 protrudes from its corresponding longitudinal beam 10. The protruding ends of the three second support beams 22 can be referred to as the first ends of the second support beams 22, and the ends of the three second support beams 22 opposite to the first ends can be referred to as the second ends. The first end can be understood as the end closer to the cooling component in the width direction of the housing 200, and the second end can be understood as the end farther from the cooling component in the width direction of the housing 200. That is, the direction from the second end to the first end is the direction indicated by the positive Y-axis. Thus, in the width direction of the housing 200, a receiving space is formed between the first ends of the three second support beams 22 and the corresponding longitudinal beams 10. This receiving space can be used to install all or part of the cooling component structure. Therefore, in the width direction of the housing 200, the cooling component does not occupy additional space or reduces the space it occupies in the width direction. This allows for more space to be left in the width of the enclosure 200, creating a maintenance space that facilitates the inspection and maintenance of the battery pack 400 within the enclosure 200, avoiding the need to remove the battery pack 400 or the entire bracket from the enclosure 200 for inspection and maintenance.

[0045] It should be noted that the dimensions of the three second support beams 22 in the width direction of the housing 200 are adapted to the dimensions of the battery pack 400. That is, the dimensions of the second support beams 22 in the width direction of the housing 200 are the same as or slightly larger than the dimensions of the battery pack 400 in that direction. This not only provides relatively stable support for the battery pack 400 but also prevents the mounting unit 20 from occupying excessive space. In this way, the cooling assembly utilizes the space occupied by the battery pack 400 in the width direction of the housing 200, meaning that the cooling assembly will not occupy space in the width direction of the housing 200 when installed, thus saving at least some space in that direction.

[0046] For example, Figure 6 and Figure 8As shown, the four longitudinal beams 10 may include, for example, two first longitudinal beams 11 and two second longitudinal beams 12. The two first longitudinal beams 11 are positioned near their first ends, and the two second longitudinal beams 12 are positioned near their second ends. Specifically, in the length direction of the box body 200, the two first longitudinal beams 11 are positioned opposite each other, and the two second longitudinal beams 12 are positioned opposite each other. In the width direction of the box body 200, the first ends of the three second support beams 22 protrude beyond the two first longitudinal beams 11.

[0047] Furthermore, such as Figure 3 and Figure 7 As shown, multiple reinforcing ribs 13 are provided between the first longitudinal beam 11 and the second longitudinal beam 12 to improve the overall strength of the support. For example, the multiple reinforcing ribs 13 are arranged obliquely between the first longitudinal beam 11 and the second longitudinal beam 12; and the multiple reinforcing ribs 13 are evenly arranged along the height direction of the box 200 so that the support has high strength at all locations.

[0048] Preferably, each second longitudinal beam 12 is provided with a positioning part 121, which extends away from the second longitudinal beam 12 along the length direction of the housing 200. That is, in the orthographic projection of the housing 200 in the width direction, the positioning part 121 and the mounting unit 20 have an overlapping area. The battery pack 400 can be pushed into the mounting unit 20 from the first end to the second end (that is, in the width direction of the housing 200). When the battery pack 400 abuts against the positioning part 121, it means that the battery pack 400 has been pushed into the predetermined mounting position, and at this time the battery pack 400 can be fixed.

[0049] See also Figure 6 and Figure 7 The mounting unit 20 also includes a locking beam 23. The locking beam 23 may be parallel to the two first support beams 21, for example. Alternatively, it can be understood that the locking beam 23 is perpendicular to the three second support beams 22. The locking beam 23 may be located at the first end of the three second support beams 22, with its two ends and middle portion connected to the first end of their respective second support beams 22 to fix the locking beam 23 to the three second support beams 22. When the battery pack 400 is pushed into the mounting unit 20, the locking beam 23 can lock the battery pack 400, thus securing the battery pack 400 to the mounting unit 20.

[0050] For example: See Figures 11 to 15The battery pack 400, for example, has a first wall portion 401 and a second wall portion 402, which are arranged opposite to each other along the width direction of the housing 200. Thus, when the battery pack 400 is pushed into the mounting unit 20 along the width direction of the housing 200, its second wall portion 402 abuts against the positioning part 121, indicating that it has been pushed into the predetermined mounting position. At this time, the position of the first wall portion 401 corresponds to the locking beam 23, and the first wall portion 401 can be connected to the locking beam 23 using bolts or other fasteners. In this way, the battery pack 400 can be fixed in the mounting unit 20 by the combined action of the positioning part 121 and the locking beam 23.

[0051] Specifically, the positioning part 121 may be provided with a positioning hole 1211, and the second wall part 402 may be provided with a positioning pin that matches the positioning hole 1211. When the battery pack 400 is pushed into the mounting unit 20, the positioning pin will be inserted into the corresponding positioning hole 1211. Under the combined action of the positioning pin and the positioning hole 1211, the height and length directions of the battery pack 400 can be limited. In addition, the first wall part 401 may be provided with a connection structure that matches the locking beam 23. For example, the connection structure and the locking beam 23 may be provided with corresponding bolt holes, and the connection between the connection structure and the locking beam 23 can be achieved by fasteners such as bolts. Under the combined action of the connection structure and the locking beam 23, the width direction of the battery pack 400 can be limited. In this way, under the action of the positioning part 121 and the locking beam 23, the battery pack 400 can be limited in three directions, and the battery pack 400 can be stably fixed in the mounting unit 20.

[0052] During the installation and fixing of the battery pack 400, it can be pushed into the external bracket. Simultaneously, the positioning pin inserts into the positioning hole 1211, limiting the height and length of the battery pack 400 without additional tightening, saving time. Afterward, simply tightening the first wall 401 to the locking beam 23 secures the battery pack 400. Only one tightening operation is required throughout the entire process. Similarly, when disassembling the battery pack 400, simply removing the locking mechanism between the first wall 401 and the locking beam 23 allows the positioning pin to separate from the positioning hole 1211 and the battery pack 400 to be removed from the mounting unit 20 by pulling. Thus, the tightening operation is significantly reduced during installation and disassembly, saving time and enabling quick installation and removal of the battery pack 400. This not only improves the efficiency of battery pack 400 assembly and disassembly, but also saves production costs due to its simple structure.

[0053] As an alternative implementation method, such as Figure 6 As shown, the distance between the edge of the locking beam 23 away from the two first longitudinal beams 11 and the two first longitudinal beams 11 is L1mm, and the value of L1mm ranges from 110mm to 150mm. This distance can be understood, for example, as the distance between the edge of the locking beam 23 away from the two first longitudinal beams 11 and the surface of the first longitudinal beam 11 facing the locking beam 23. This distance can also be understood, for example, as the distance between the first end and the first longitudinal beam 11 in the width direction of the housing 200. The locking beam 23 and the first longitudinal beam 11 satisfying the above range allow for a sufficiently large accommodating space between them to facilitate the installation of cooling components; on the other hand, it prevents the space between them from being too large, thus avoiding the first end protruding too far from the first longitudinal beam 10 and affecting the supporting strength of the end of the second support beam 22.

[0054] The value of L1mm can be, for example, 110mm, 115mm, 118mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, or 150mm. In use, the value of L1mm can be adjusted adaptively according to factors such as the size of the battery pack 400 and the material and strength of the second support beam 22, and is not limited to the values ​​listed above.

[0055] As an optional implementation method, such as Figure 8 and Figure 9 As shown, the positioning part 121 can be connected to the second longitudinal beam 12 via a specific connecting structure. This connecting structure can extend a certain distance along the length of the housing 200, allowing the positioning part 121 to limit the position of the battery pack 400. This connecting structure can be, for example, a channel steel with a certain strength, with one end connected to the second longitudinal beam 12, and the positioning part 121 can be located, for example, at the end of the channel steel away from the second longitudinal beam 12.

[0056] Preferably, in the longitudinal direction of the housing 200, the length of the mounting unit 20 is L2mm, and the distance between the positioning hole 1211 and the second longitudinal beam 12 is L3mm, where 0.035≤L3mm / L2mm≤0.085. The length of the mounting unit 20 can be understood, for example, as the distance between the two first longitudinal beams 11 or the distance between the two second longitudinal beams 12. Taking the distance between the two second longitudinal beams 12 as an example: the length L21 of the mounting unit 20 can be understood as the distance between the two facing surfaces of the two second longitudinal beams 12. The distance between the positioning hole 1211 and the second longitudinal beam 12 can be understood, for example, as the distance between the center of the positioning hole 1211 and the surface of the second longitudinal beam 12 facing the positioning part 121.

[0057] The positioning part 121 and the mounting unit 20 that meet the above-mentioned range can, on the one hand, make the extension distance of the positioning part 121 large enough so that it can play a good role in limiting and fixing the battery pack 400; on the other hand, they can also prevent the positioning part 121 from extending too far, thus avoiding insufficient strength of the positioning part 121 due to the large distance between it and the second longitudinal beam 12.

[0058] The ratio of L3mm / L2mm can be, for example, 0.035, 0.040, 0.045, 0.050, 0.055, 0.060, 0.065, 0.070, 0.075, 0.080, or 0.085.

[0059] Optionally, the value of L2mm ranges from 700mm to 900mm. For example, the value of L2mm can be 700mm, 720mm, 750mm, 780mm, 800mm, 810mm, 830mm, 850mm, 860mm, or 900mm, etc. The value of L3mm ranges from 30mm to 60mm. For example, the value of L3mm can be 30mm, 35mm, 40mm, 42mm, 45mm, 48mm, 50mm, 52mm, 55mm, 58mm, or 60mm, etc. In use, the values ​​of L2mm and L3mm can be adaptively adjusted according to comprehensive factors such as the size of the battery pack 400 and the material of the second longitudinal beam 12, and are not limited to the values ​​listed above.

[0060] like Figure 3 and Figure 7 As shown, the cooling assembly is used to cool the battery pack 400 to prevent it from overheating during use. The cooling assembly includes, for example, multiple first pipes 31 and multiple second pipes 32, where the first pipes 31 can be understood as upstream pipes of the second pipes 32. Thus, the multiple first pipes 31 can be connected to multiple battery packs 400 through the multiple second pipes 32.

[0061] Specifically, each bracket can be equipped with at least two first pipes 31. Taking the example of each bracket being equipped with two first pipes 31, one of the first pipes 31 can be defined as an inlet pipe, which delivers external cooling water or other cooling media to each of the second pipes 32; the other first pipe 31 can be defined as an outlet pipe, which outputs the cooling water or other cooling media after heat exchange in the second pipe 32.

[0062] The two first pipes 31 can extend along the height direction of the housing 200, and the two first pipes 31 can be arranged on both sides of the mounting unit 20 and connected to the two first longitudinal beams 11 along the length direction of the housing 200. That is, in the width direction of the housing 200, the first pipes 31 are located between the first end and the first longitudinal beam 11, so that the first pipes 31 can utilize the space of the second support beam 22 in the width direction and will not occupy additional space in the width of the housing 200, thus saving at least some space in the width direction of the housing 200.

[0063] like Figure 7 As shown, the first conduit 31 can be connected to the first longitudinal beam 11, for example, via a first connecting plate 111. The first connecting plate 111 can extend a certain distance along the width direction of the housing 200 to prevent interference between the first conduit 31 and the first longitudinal beam 11 when the first conduit 31 is fixed. Of course, the extension distance of the first connecting plate 111 in the width direction of the housing 200 should not exceed the locking beam 23.

[0064] As an optional implementation, the two first pipes 31 do not extend beyond the first longitudinal beam 11 along the length of the housing 200. That is, the outer diameter of the first pipe 31 does not exceed the outer diameter of the first longitudinal beam 11 along the length of the housing 200. Thus, the first pipe 31 can utilize the space of the first longitudinal beam 11 along its length, without occupying additional space along the length of the housing 200, thereby saving at least some space along the length of the housing 200.

[0065] It is understood that each battery pack 400 may include, for example, two second pipes 32. One second pipe 32 can be defined as a water inlet pipe for supplying cooling medium such as cooling water into the battery pack 400. One end of this second pipe 32 is connected to the battery pack 400, and the other end is connected to the first water inlet pipe 31. The other second pipe 32 can be defined as a water outlet pipe for discharging the cooled cooling medium such as cooling water from the battery pack 400. One end of this second pipe 32 is connected to the battery pack 400, and the other end is connected to the first water outlet pipe 31.

[0066] The connection point between the second conduit 32 and the battery pack 400 can be, for example, located on the first wall portion 401, specifically on the surface of the battery pack 400 near the locking beam 23. This way, when the battery pack 400 is fixed to the mounting unit 20, the connection point can face the maintenance access channel 300, facilitating operation by personnel. Simultaneously, the connection point of the second conduit 32 on the first conduit 31 needs to be determined based on the height of the battery pack 400 on the bracket to minimize the connection distance between the second conduit 32 and the battery pack 400.

[0067] It should be noted that, since one end of the second pipe 32 needs to connect to the first wall 401 of the battery pack 400, the second pipe 32 cannot be completely accommodated within the space between the first end and the first longitudinal beam. That is, the second pipe 32 will occupy some space in the width direction of the housing 200. In use, the extension distance of the second pipe 32 in this direction can be minimized to reduce the space it occupies in the width direction of the housing 200. At the same time, to ensure safety, the second pipe 32 can be, for example, a flexible hose made of rubber or plastic; the first pipe 31 can be, for example, a rigid pipe made of steel or aluminum to ensure the supporting strength of the first pipe 31 for the second pipe 32.

[0068] As an optional implementation method, such as Figure 17 As shown, when multiple battery pack holders 100 are placed inside the housing 200, there are maintenance channels 300 between the multiple battery pack holders 100, meaning there is a relatively large gap between two battery pack holders 100. Thus, cooling components and piping can be added, for example, a third piping 33 can be added. The third piping 33 can be understood as a superior piping to the first piping 31, and all first piping 31 can converge into the third piping 33. It is understood that the third piping 33 can also be configured as two, one inlet piping and one outlet piping. The third piping 33 for inlet water is connected to each of the first piping 31 for inlet water; the third piping 33 for outlet water can be connected to each of the first piping 31 for outlet water. In use, the number and level of piping can be increased or decreased according to requirements; this application does not impose specific limitations on this.

[0069] See Figure 4 and Figure 5 The battery pack mounting bracket 100 can have multiple supports arranged along the length of the housing 200, with adjacent supports interconnected. For example, both the first longitudinal beam 11 and the second longitudinal beam 12 have multiple through holes 123, which extend through the first longitudinal beam 11 and the second longitudinal beam 12 along the length of the housing 200. Bolts or other fasteners pass through the multiple through holes 123 on the first longitudinal beam 11 and the second longitudinal beam 12, respectively, to connect adjacent supports.

[0070] It is understandable that multiple through holes 123 can be evenly arranged on the first longitudinal beam 11 and the second longitudinal beam 12 along the height direction of the housing 200, so that the force can be evenly distributed between adjacent supports, improving the stability of the connection between the two supports. Preferably, the through holes 123 can be set as strip holes, and the length direction of the strip holes is parallel to the height direction of the housing 200. In this way, when connecting adjacent supports, the strip holes can compensate for certain installation errors.

[0071] See Figures 4 to 16 The enclosure 200 includes a base plate 201 and side walls 202, with the side walls 202 connected to the periphery of the base plate 201. The base plate 201 and side walls 202 are interconnected to form a receiving space within the enclosure 200, where the battery pack holders 100 can be placed, for example. As described above, taking the placement of two battery pack holders 100 within the enclosure 200 as an example: the two battery pack holders 100 are arranged opposite each other along the width of the enclosure 200, and the space between the two battery pack holders 100 forms a maintenance passage 300. Personnel can enter the maintenance passage 300 to perform inspection and maintenance on the battery packs 400.

[0072] The side wall 202 includes a first side wall and a second side wall arranged opposite to each other along the width direction of the housing 200. Two battery pack holders 100 can be respectively disposed close to the first side wall and the second side wall. That is, one battery pack holder 100 is connected to the first side wall and the other battery pack holder 100 is connected to the second side wall.

[0073] Specifically, such as Figure 4 and Figure 5 As shown, a plurality of connectors 122 are provided on the surface of the second longitudinal beam 12 facing the first and second side walls, and the plurality of connectors 122 are arranged at intervals along the height direction of the second longitudinal beam 12. One battery pack mounting bracket 100 is connected to the first side wall through the plurality of connectors 122; another battery pack mounting bracket 100 is connected to the second side wall through the plurality of connectors 122.

[0074] Preferably, the connector 122 and the second longitudinal beam 12 can be connected by welding, for example, to achieve a high connection strength. The side of the connector 122 closest to the first and second sidewalls can be, for example, a plate-like plane to increase the contact area between the connector 122 and the first and second sidewalls, thereby increasing the connection strength between the connector 122 and the first and second sidewalls.

[0075] For example, the plate-shaped plane of the connector 122 is provided with a plurality of strip holes arranged at intervals along its height direction. By passing fasteners such as bolts through the plurality of strip holes, the connector 122 can be connected to the first side wall and the second side wall, thereby fixing each bracket to the first side wall or the second side wall.

[0076] It should be noted that the positioning part 121 is located on the surface of the second longitudinal beam 12 facing away from the first or second side wall. That is, the positioning part 121 and the connector 122 are respectively disposed on two opposite surfaces of the second longitudinal beam 12, with the positioning part 121 located on the surface of the second longitudinal beam facing the mounting unit. Thus, the positioning part 121 and the connector 122 will not interfere with each other. The positioning part 121 is closer to the battery pack 400 than the connector 122. When the battery pack 400 is pushed into the mounting unit 20, it will connect with the positioning part 121 earlier to perform initial positioning of the battery pack 400, avoiding interference from the connector 122.

[0077] Furthermore, such as Figure 5 As shown, in the height direction of the housing 200, the positioning part 121 and multiple connectors 122 are arranged alternately. That is, the positioning part 121 and the connectors 122 are located at different heights of the second longitudinal beam 12, further avoiding mutual interference between them. For example, when the battery pack 400 is pushed into the mounting unit 20, the positioning pin on the battery pack 400 can be prevented from hitting the connector 122, thus avoiding affecting the accurate positioning of the battery pack 400 or the strength of the connector 122.

[0078] As described above, the housing 200 includes a base plate 201, and multiple supports can be fixed to the base plate 201, for example, via a frame 50. Figure 10 As shown, the frame 50 includes two crossbeams 51 and multiple third connecting beams 52. The two crossbeams 51 extend along the length of the housing 200. The extension length of the crossbeams 51 on the housing 200 can be, for example, equal to or slightly greater than the length of the battery pack mounting bracket 100, so as to stably fix the battery pack mounting bracket 100 to the base plate 201, while also preventing the frame 50 from occupying too much space in the length direction of the housing 200.

[0079] Multiple third connecting beams 52 are also provided between the two crossbeams 51. The multiple third connecting beams 52 are parallel to each other and perpendicular to the two crossbeams 51, so that each third connecting beam 52 can be connected to the two crossbeams 51 through its two ends. In this way, the stability and strength of the entire frame 50 are improved, thereby enabling better fixation of the battery pack mounting bracket 100 to the base plate 201.

[0080] Each bracket also includes multiple first connecting beams 24 and multiple second connecting beams 25. The multiple first connecting beams 24 are parallel to and connected to the two crossbeams 51, and the multiple second connecting beams 25 are parallel to and connected to the multiple third connecting beams 52.

[0081] For details, please refer to Figures 1 to 9Each support has the same structure at its top and bottom. The bottom can be understood as the end of the support closer to the base plate 201, and the top as the end of the support furthest from the base plate 201. Each support includes, for example, two first connecting beams 24 and four second connecting beams 25 at its top and bottom. Taking the bottom of the support as an example: the two first connecting beams 24 can be parallel to the crossbeam 51, and are located between the two first longitudinal beams 11 and the two second longitudinal beams 12, respectively. Thus, the two ends of one first connecting beam 24 are connected to the bottom ends of the two first longitudinal beams 11, and the two ends of the other first connecting beam 24 are connected to the bottom ends of the second longitudinal beams. Meanwhile, the four second connecting beams 25 are parallel to each other and located between the two first connecting beams 24. The two outermost second connecting beams 25 are located between the first longitudinal beam 11 and the second longitudinal beam 12, respectively. That is, the two outermost second connecting beams 25 are connected to the bottom ends of the first longitudinal beam 11 and the second longitudinal beam 12, respectively. The two middle second connecting beams 25 are connected at both ends to the two first connecting beams 24, respectively. Furthermore, the two first connecting beams 24 are connected to the two crossbeams 51, respectively; and the two middle second connecting beams 25 are connected to their corresponding third connecting beams 52. In this way, each bracket can be fixed to the frame 50.

[0082] Furthermore, such as Figure 10 As shown, the frame 50 may also include a plurality of second connecting plates 53, which can be used to fix the frame 50 to the base plate 201, thereby achieving the fixation between the battery pack mounting bracket 100 and the base plate 201. Preferably, the plurality of second connecting parts 53 can be evenly arranged on the two crossbeams 51 along the length direction of the housing 200 so that the battery pack mounting bracket 100 can be evenly stressed at all points.

[0083] As an optional implementation method, such as Figure 4 and Figure 16 As shown, the housing 200 has an outlet on one side along its length. The height of the bracket closest to the outlet among the multiple brackets is less than the height of the others, so that a fan 40 can be mounted on its top surface. The fan 40 can be fixed to the top surface of the bracket, for example, via its bottom surface, and / or to an adjacent bracket via its side surface. The specific fixing method can be adapted to the actual situation to ensure the stability of the fan 40 during use.

[0084] Understandably, the fan 40 connects the internal space of the container 200 with its external space, enabling air circulation between the inside and outside of the container 200. When the temperature inside the container 200 becomes too high, or in the event of localized thermal runaway such as combustion or explosion, the fan 40 can promptly expel the heat from inside the container 200, ensuring the safety of the container's power supply. Positioning the fan 40 on the bracket closest to the outlet minimizes the distance between the fan 40 and the outside of the container 200, allowing for timely and efficient heat removal in the event of thermal runaway.
