Description

Technical Field

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

[0002] With the continuous development of energy storage technology, the application of energy storage cabinets is becoming increasingly widespread. For example, energy storage cabinets can be used in containerized energy storage systems for outdoor energy storage. The energy storage cabinet contains a battery pack, and the cells contained in the battery pack can switch between charging and discharging states. The battery pack can serve as an energy source, enabling the energy storage cabinet to stably and continuously output electrical energy.

[0003] The energy storage cabinet provides space for components such as battery packs. Besides housing the battery packs, the cabinet also needs to accommodate the main unit connected to them, which converts DC power to AC power. The wiring between the main unit and the battery packs is influenced by the cabinet's internal layout. Ensuring sufficient battery capacity while facilitating efficient wiring within the cabinet is a crucial issue. Summary of the Invention

[0004] The purpose of this application is to provide a cabinet structure and energy storage cabinet that facilitates the wiring arrangement inside the cabinet while ensuring battery capacity.

[0005] To address the aforementioned technical problems, embodiments of this application provide a cabinet structure, comprising a cabinet and a first support. The cabinet includes a first accommodating space and a second accommodating space separated along a first direction, and a channel connecting the first accommodating space and the second accommodating space. One of the first accommodating space and the second accommodating space is provided with a host mounting position and a battery pack mounting position, while the other of the first accommodating space is provided with at least one battery pack mounting position. The first direction is parallel to the height direction of the cabinet. The first support is disposed within the first accommodating space, and the first support is used to support the host and / or battery pack and forms a wiring space at one end of the channel. The first support is provided with a wiring channel for cables to pass through, and the wiring channel is connected to the wiring space.

[0006] An embodiment of this application also provides an energy storage cabinet, which includes a main unit, multiple battery packs, and the aforementioned cabinet structure. The battery packs are electrically connected to the main unit. The main unit mounting position in the cabinet structure accommodates the main unit, and the battery pack mounting position in the cabinet structure accommodates the battery packs.

[0007] The cabinet structure and energy storage cabinet provided in this application have multiple separate accommodating spaces inside the cabinet, which can be used to house the main unit and battery packs. By arranging the accommodating spaces sequentially along a first direction, the width of the cabinet can be reduced, thereby allowing for the placement of more battery packs in situations where the energy storage cabinet installation space is limited, ensuring the battery capacity of the energy storage cabinet. Simultaneously, a first support is provided within the first accommodating space. The first support supports the main unit and / or battery pack within the first accommodating space and forms a wiring space at one end of the channel connecting different accommodating spaces. The first support also has a wiring channel, thereby facilitating the wiring arrangement of connecting cables between the main unit and each battery pack, improving the wiring convenience when the main unit and battery packs are installed separately.

[0008] In some embodiments, the cabinet structure further includes a support member extending along a first direction. The support member is disposed within a second accommodating space, which has multiple battery pack mounting positions. The support member has a cable routing channel and is located between two adjacent battery pack mounting positions. In this way, the support member can strengthen the structural strength of the cabinet and simultaneously limit the movement of the main unit or battery pack inside the cabinet.

[0009] In some embodiments, the cabinet includes a first cabinet and a second cabinet connected together. The interior of the first cabinet forms a first receiving space, and the interior of the second cabinet forms a second receiving space. The first cabinet has a first through hole, and the second cabinet has a second through hole, which communicates with the first through hole to form a channel. In this way, by combining different cabinets, the manufacturing process of the cabinet can be simplified while ensuring the structural strength of the cabinet.

[0010] In some embodiments, the first cabinet includes a plurality of first cabinet panels arranged around a second direction, and the second cabinet includes a plurality of second cabinet panels arranged around the second direction. The length of the first cabinet panels in the second direction is greater than the length of the second cabinet panels in the second direction, and the second direction is perpendicular to the first direction. In this way, by making the length of the first cabinet in the second direction greater than the length of the second cabinet in the second direction, clearance space can be provided for components such as controllers in the integrated cabinet.

[0011] In some embodiments, the first cabinet and / or the second cabinet further include a first limiting member and a second limiting member disposed opposite each other along a second direction, wherein the length of the first limiting member and the second limiting member in the first direction is greater than the length of the first bracket in the first direction. This allows the limiting members to restrict the position of the main unit or battery pack within the accommodating space.

[0012] In some embodiments, the cabinet structure further includes a cover fitting connected to one side of the second cabinet, forming a third receiving space communicating with the second receiving space on one side of the second cabinet. This allows for the creation of a third receiving space on one side of the second receiving space, facilitating the arrangement of connecting cables and electronic components.

[0013] In some embodiments, the first cabinet is provided with a third through hole, the projection of which in the first direction is located outside the edge of the second cabinet, and the third through hole communicates with a third receiving space. This allows connecting cables to pass through and enter different receiving spaces via the third through hole.

[0014] In some embodiments, the third through hole and the first through hole are disposed on the first cabinet in a second direction, away from each other. In this way, by distancing the third through hole from the first through hole, it is convenient for the connecting cables on the rear of the main unit to enter another receiving space from different positions, thus facilitating the formation of a connection loop.

[0015] In some embodiments, the first bracket includes a main body and a plurality of lugs connected to the main body. The main body has a groove and notches on both sides of the groove. The groove communicates with a wiring space through the notches, and the lugs are connected to the cabinet. In this way, a receiving space can be formed by the groove at the bottom of the first bracket, and the notches facilitate the passage of connecting cables.

[0016] In some embodiments, there are multiple first supports, which are spaced apart from each other within a first receiving space. This ensures stable support for the main unit or battery pack by using multiple first supports.

[0017] In some embodiments, the cabinet structure further includes a second support, disposed within a second receiving space, for supporting the battery pack. This allows the battery pack to be assembled within the second receiving space via the second support.

[0018] In some embodiments, the first bracket and / or the second bracket are provided with multiple mounting holes for the insertion portion at the bottom of the main unit or battery pack to pass through. This allows the main unit or battery pack to be positioned within the mounting holes on the bracket. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0035] Energy storage cabinets typically house multiple battery packs connected to a main unit. The main unit then supplies the load with the stored energy from the battery packs. Energy storage cabinets can also function as uninterruptible power supplies (UPS). When mains power is available, the cabinet stabilizes the mains voltage before supplying it to the load, and simultaneously charges the battery packs. In the event of an abnormal mains power input, the cabinet converts the DC power from the battery packs to AC power for the load.

[0036] When designing the cabinet structure of an energy storage unit, it is necessary to consider not only the arrangement of the main unit and battery packs, but also the wiring connection between them. In practical applications, the arrangement of the main unit and battery packs needs to take into account the size of the space reserved for the uninterruptible power supply (UPS) in the outdoor energy storage unit. The size of the space reserved for the UPS will affect the number of battery packs that can be placed, thus affecting the energy storage density of the energy storage unit.

[0037] In containerized energy storage systems used in outdoor applications, the width space reserved for uninterruptible power supplies (UPS) within the integrated cabinet is limited. Therefore, it is necessary to consider layering the battery packs vertically. After layering the battery packs, since each battery pack needs to be electrically connected to the main unit, the wiring arrangement between the main unit and the battery packs needs to be considered.

[0038] To ensure battery capacity while facilitating internal wiring arrangement, some embodiments of this application provide a cabinet structure. The cabinet is layered with different accommodating spaces along a predetermined direction to increase the number of battery packs that can be accommodated. Supports are also provided within these spaces to support the main unit or battery packs, creating wiring space at the bottom of each space. This wiring space connects to a passageway, allowing connecting cables between battery packs and the main unit on different layers to pass through, facilitating the arrangement of these cables.

[0039] The following is combined with Figures 1 to 12 This application describes the cabinet structure provided in some embodiments.

[0040] like Figures 1 to 12 As shown, some embodiments of this application provide a cabinet structure including a cabinet 11 and a first support 12. The cabinet 11 includes a support along a first direction ( Figure 1 The first accommodating space 101 and the second accommodating space 102 are separated by the direction indicated by the middle arrow P, and a channel connects the first accommodating space 101 and the second accommodating space 102. One of the first accommodating space 101 and the second accommodating space 102 is provided with a host mounting position 1011 and a battery pack mounting position 1012. The other of the first accommodating space 101 and the second accommodating space 102 is provided with at least one battery pack mounting position 1012. A first bracket 12 is provided in the first accommodating space 101. The first bracket 12 is used to support the host and / or the battery pack and forms a wiring space 103 at one end of the channel. The first bracket 12 is provided with a wiring channel 1201 for cables to pass through. The wiring channel 1201 is connected to the wiring space 103.

[0041] The cabinet 11 provides storage space for components such as the main unit and battery pack. Multiple storage spaces are provided inside the cabinet 11 in a first direction; in this embodiment, a first storage space 101 and a second storage space 102 are used for illustration. The first storage space 101 and the second storage space 102 are separated in the first direction. This separation can be achieved by installing a partition inside the cabinet 11, or by using a spliced ​​design where different storage spaces are formed within different cabinets 11 and separated by the cabinet panels of the spliced ​​cabinets 11. The first direction is the vertically downward direction when the cabinet 11 is in use, that is, the first direction is parallel to the height direction of the cabinet 11.

[0042] In actual installation, the main unit's wiring side is at the rear, while the battery pack's wiring side is at the front. The wiring between the main unit and the battery pack needs to pass through the partitions between the different storage spaces and needs to be routed between the front and rear sides of cabinet 11. Here, the front side refers to the side of the energy storage cabinet that faces the operator and can operate and control it when in use, and the rear side refers to the side of the energy storage cabinet that faces away from the operator when in use.

[0043] One of the first receiving space 101 and the second receiving space 102 is provided with a host mounting position 1011 and a battery pack mounting position 1012, and the other of the first receiving space 101 and the second receiving space 102 is provided with at least one battery pack mounting position 1012. The host mounting position 1011 is used to place the host, and the battery pack mounting position 1012 is used to place the battery pack. In the receiving space, the host and the battery pack are arranged side by side, and in the other receiving space, one or more battery packs can be placed, and multiple battery packs can be arranged side by side.

[0044] The first receiving space 101 and the second receiving space 102 form a channel at the separation position. There can be one or more channels. The channel allows wiring to pass through the separation position between the layers for electrical connection between the main unit and the battery pack. The first direction is the vertically downward direction when the energy storage cabinet is in use, and the first receiving space 101 is located above the second receiving space 102. That is, the bottom of the first receiving space 101 is close to the separation position between the different receiving spaces.

[0045] The first bracket 12 is located within the first receiving space 101 and supports the main unit and / or battery pack placed within the first receiving space 101, thereby forming a wiring space 103 at the bottom of the main unit and / or battery pack, i.e., the bottom of the main unit and / or battery pack is separated from the bottom wall of the corresponding first receiving space 101. While supporting the main unit and / or battery pack, the first bracket 12 also provides a wiring channel 1201, allowing the connecting cables 21 between the main unit and each battery pack to pass through the first bracket 12, thus completing the wiring arrangement within the wiring space 103. When the connecting cables 21 need to cross the dividing points of different receiving spaces, they can pass through the channel, entering from one receiving space to another.

[0046] like Figure 3 and Figure 4 As shown, the first accommodating space 101 is located above the second accommodating space 102. The first accommodating space 101 can house the main unit and battery pack, while the second accommodating space 102 can house two battery packs. A portion of the wiring from the rear of the main unit passes through a channel into the second accommodating space 102, is connected in series with the two battery packs, and then returns to the rear of the main unit via the channel to the first accommodating space 101, where it is connected in series with the battery packs and then back to the rear of the main unit. The wiring from the rear of the main unit can be routed to the front of the battery packs via the wiring space 103.

[0047] The cabinet structure provided in some embodiments of this application includes multiple separate accommodating spaces within the cabinet 11, which can be used to house the main unit and battery packs. By arranging the accommodating spaces sequentially along a first direction, the width of the cabinet 11 can be reduced, thereby allowing for the placement of more battery packs within the limited installation space of the energy storage cabinet, ensuring the battery capacity of the energy storage cabinet. Simultaneously, a first support 12 is provided within the first accommodating space 101. The first support 12 supports the main unit and / or battery pack within the first accommodating space 101 and forms a wiring space 103 at one end of the channel connecting different accommodating spaces. The first support 12 also has a wiring channel 1201, thereby facilitating the wiring arrangement of the connecting cables 21 between the main unit and each battery pack, improving the wiring convenience when the main unit and battery pack are installed separately.

[0048] In some embodiments, the cabinet structure further includes a support member 13 extending along a first direction, the support member 13 being disposed within a second accommodating space 102, the second accommodating space 102 being provided with a plurality of battery pack mounting positions 1012. The support member 13 is provided with a wiring channel, and the support member 13 is located between two adjacent battery pack mounting positions 1012.

[0049] The support member 13 extends along the first direction, that is, the support member 13 is arranged in a long strip shape, and the support member 13 can play a supporting role within the accommodating space. At the same time, the support member 13 is provided with a cable routing groove, which can provide accommodating space for arranging the connecting cables 21.

[0050] Furthermore, the second accommodating space 102 is provided with multiple battery pack mounting positions 1012, which can accommodate multiple battery packs. Support members 13 are arranged between two adjacent battery pack mounting positions 1012, serving to limit the movement of the battery packs in the lateral direction. The number of support members 13 can be one or more, with multiple support members 13 spaced apart within the second accommodating space 102. In practice, the support member 13 may include a flat plate portion and two opposing extension portions located at the edge of the flat plate portion, with the two extension portions and the flat plate portion forming a cable routing groove. Through holes may also be provided on the sidewall of the support member 13, allowing for the installation of binding straps or other securing devices to bind cables.

[0051] In practice, the support member 13 can also be extended to the first accommodating space 101, that is, the support member 13 can be extended completely from the bottom of the cabinet 11 to the top of the cabinet 11. The support member 13 with a longer extension length inside the cabinet 11 can be used to arrange and fix the connecting cable 21, thereby reducing the number of wiring through holes inside the cabinet 11 and simplifying the structure of the cabinet 11.

[0052] Additionally, an independent wiring space can be formed in the central area of ​​the cabinet 11, where the connecting cables 21 can be arranged as a whole. This wiring space can both separate different installation positions within the housing space and limit the movement of the main unit or battery pack within the housing space by using the partitions that form the wiring space, ensuring the stability of the main unit or battery pack within the housing space.

[0053] In some embodiments, the cabinet 11 may include a first cabinet 111 and a second cabinet 112 connected together. The interior of the first cabinet 111 forms a first accommodating space 101, and the interior of the second cabinet 112 forms a second accommodating space 102. The first cabinet 111 is provided with a first through hole 1112, and the second cabinet 112 is provided with a second through hole 1122. The second through hole 1122 communicates with the first through hole 1112 to form a channel.

[0054] The first cabinet 111 and the second cabinet 112 are combined to form the cabinet structure of the energy storage cabinet. The first cabinet 111 is stacked on the second cabinet 112 in a first direction, and the two can be connected to form a whole by fasteners or connectors 1102. The first accommodating space 101 is located inside the first cabinet 111, and the second accommodating space 102 is located inside the second cabinet 112. Through holes are provided on the first cabinet 111 and the second cabinet 112 respectively to form a channel connecting the different accommodating spaces. The first through hole 1112 is located at the bottom of the first cabinet 111, and the second through hole 1122 is located at the top of the second cabinet 112. The through holes on the different cabinets 11 are connected to form a channel.

[0055] By using different complete cabinets to create different storage spaces, the cabinet structure can be simplified while ensuring the structural strength of each complete cabinet. For example... Figures 3 to 5 As shown, both the first cabinet 111 and the second cabinet 112 can be set into a regular shape. The first cabinet 111 is stacked on the second cabinet 112. The first cabinet 111 and the second cabinet 112 can be connected and fixed on the left and right sides using connectors 1102.

[0056] In practice, a gap can be reserved between the first cabinet 111 and the second cabinet 112, forming a reserved space between them. A supporting component is installed on top of the second cabinet 112 to support the first cabinet 111. This reserved space allows for the arrangement of connecting cables 21. The connecting cables 21 on the rear of the main unit can first be led out of the cabinet 11 and then pass through the reserved space between the first and second cabinets 111 and 112. The connecting cables 21 entering the reserved space can reach the front of the cabinet 11, and then pass through different compartments within the cabinet 11 to reach the front of different battery packs, thus connecting each battery pack to the main unit. Alternatively, through holes can be provided at the bottom of the first cabinet 111 or the top of the second cabinet 112, allowing the connecting cables 21 entering the reserved space to pass through and reach different compartments, thereby connecting with the battery packs.

[0057] Additionally, the first cabinet 111 may include a surrounding second direction ( Figure 5 Multiple first cabinet panels 1111 are arranged in the direction indicated by the middle arrow Q. The second cabinet 112 includes multiple second cabinet panels 1121 arranged around the second direction. The length of the first cabinet panel 1111 in the second direction is greater than the length of the second cabinet panel 1121 in the second direction. The second direction is perpendicular to the first direction.

[0058] The second direction is perpendicular to the first direction, and the second direction is the front-to-back direction when the cabinet 11 is in use. The first cabinet 111 includes multiple first cabinet panels 1111, which enclose a first accommodating space 101. Multiple second cabinet panels 1121 enclose a second accommodating space 102. Decorative panels 1101 can be installed on the front and rear sides of the first cabinet 111 and the front and rear sides of the second cabinet 112 for enclosure.

[0059] like Figure 7 and Figure 8 As shown, both the first cabinet 111 and the second cabinet 112 include four cabinet panels. Meanwhile, as... Figure 4 and Figure 5 As shown, the front side of the first cabinet 111 protrudes beyond the front side of the second cabinet 112 in the second direction, meaning that the length of the first cabinet panel 1111 of the first cabinet 111 in the second direction is greater than the length of the second cabinet panel 1121 of the second cabinet 112 in the second direction. By making the second cabinet 112, which is located below, shorter than the first cabinet 111 in the front, a clearance space can be formed to allow for the arrangement of controllers within the integrated cabinet.

[0060] In some embodiments, the first cabinet 111 and the second cabinet 112 may further include a first limiting member 14 and a second limiting member 15 disposed opposite to each other along a second direction, wherein the length of the first limiting member 14 and the second limiting member 15 in the first direction is greater than the length of the first bracket 12 in the first direction.

[0061] The first limiting member 14 and the second limiting member 15 can be baffles, which serve to limit the movement of the main unit or battery pack placed in the accommodating space at the front and rear sides of the cabinet 11. Different limiting members can be connected and fixed to the cabinet panels of the cabinet 11 using fasteners. Furthermore, the limiting members can be assembled after the main unit or battery pack is installed to avoid affecting the assembly space. The first limiting member 14 and the second limiting member 15 are higher than the first bracket 12 in the first direction to limit the main unit or battery pack located on the first bracket 12, effectively preventing easy movement of the main unit or battery pack within the accommodating space.

[0062] like Figure 5 and Figure 6 As shown, the cabinet structure may also include a cover 16, which is connected to one side of the second cabinet 112 and forms a third accommodating space 104 communicating with the second accommodating space 102 on one side of the second cabinet 112.

[0063] The cover 16 is connected to the front of the second cabinet 112, forming a receiving space on the front of the second cabinet 112. This space provides an area for the connection cable 21 between the main unit and the battery pack, as well as the electronic components on the cable. The cover 16 can be connected to the second cabinet 112 using screws or other fasteners. Simultaneously, the edge of the cover 16 can also connect to the first cabinet 111 to ensure a good connection between the cover 16 and the cabinet 11. The size of the receiving space formed by the cover 16 can be set according to actual needs. In the area near the bottom of the second cabinet 112, the cover 16 can be placed close to the edge of the second cabinet 112 to reduce space occupation and provide clearance for components such as controllers in the integrated cabinet. The portion of the cover 16 facing the third receiving space 104 can be flush with the front of the first cabinet 111 to ensure the consistency of the front shape of the cabinet 11.

[0064] In some embodiments, the first cabinet 111 may be provided with a third through hole 1113, the projection of the third through hole 1113 in the first direction is located outside the edge of the second cabinet 112, and the third through hole 1113 communicates with the third accommodating space 104.

[0065] In other words, the third through hole 1113 provided in the first cabinet 111 is located on the front side of the first cabinet 111 and communicates with the third receiving space 104 on the front side of the first cabinet 111, which facilitates the passage of the connecting cable 21 on the front side of the battery pack between different receiving spaces. The third through hole 1113 can form another independent cable passage path on the front side of the cabinet 11. The connecting cable 21 reaching the front side of the cabinet 11 can pass through the third through hole 1113 and reach different receiving spaces, so as to arrange the wiring in the receiving spaces of different parts of the cabinet 11.

[0066] In addition, the third through hole 1113 and the first through hole 1112 can be disposed on the first cabinet 111 in a second direction away from each other.

[0067] The third through hole 1113 is located on the front side of the first cabinet 111, and the first through hole 1112 is located on the rear side of the first cabinet 111. The third through hole 1113 facilitates the passage of the connecting cable 21 on the front side of the battery pack, and the first through hole 1112 facilitates the passage of the connecting cable 21 on the rear side of the main unit. By separating the third through hole 1113 and the first through hole 1112 on the front and rear sides of the first cabinet 111, the connection between the rear side of the main unit and the front side of the battery pack can be accommodated. The first cable 22 connected to the rear side of the main unit can reach the front side of the cabinet 111 through the wiring space 103, and then pass through the third through hole 1113 into the third receiving space 104, and then into the second receiving space 102. The second cable 23 connected to the rear side of the main unit can directly pass through the first through hole 1112 into the third receiving space 104. In this way, it is convenient to arrange the wiring in two directions, which can save the length of the wiring and reduce the mutual interference and influence between the wiring.

[0068] In some embodiments, the first bracket 12 may include a main body 121 and a plurality of lugs 122 connected to the main body 121. The main body 121 is provided with a groove 1202 and notches 1203 located on both sides of the groove 1202. The groove 1202 communicates with the wiring space 103 through the notches 1203, and the lugs 122 are connected to the cabinet 11.

[0069] The main body 121 is the main part of the first bracket 12, forming the foundation for supporting the main unit and / or battery pack. For example... Figures 9 to 11As shown, the groove 1202 in the main body 121 forms a hollow area for arranging the connecting cable 21. Notches 1203 are provided on both sides of the groove 1202, allowing the connecting cable 21 to pass through or exit from the groove 1202. The lug 122 is the part that connects the first bracket 12 to the cabinet 11. The lug 122 protrudes from the surface of the main body 121 and has through holes for fasteners to pass through, so that the first bracket 12 can be fixed to the bottom of the first receiving space 101 by fasteners.

[0070] In addition, there can be multiple first supports 12, and multiple first supports 12 are arranged at intervals within the first receiving space 101.

[0071] Multiple first supports 12 are arranged at different positions within the first receiving space 101, and different first supports 12 can play a supporting role at different positions. For example Figure 6 As shown, there are two first supports 12, which are separately arranged on the left and right sides of the first receiving space 101 to ensure stability when supporting the main unit and battery pack. Simultaneously, the separate arrangement of multiple first supports 12 allows sufficient space within the first receiving space 101 for the arrangement of connecting cables 21. In practice, the first supports 12 can also be arranged in the central area of ​​the first receiving space 101, providing support in the middle area.

[0072] In some embodiments, the cabinet structure may further include a second support 17 disposed within the second receiving space 102, the second support 17 being used to support the battery pack.

[0073] The second bracket 17 is located within the second accommodating space 102. The second bracket 17 can adopt the same structure as the first bracket 12 to facilitate cable routing. Alternatively, the second bracket 17 may not have a cable routing channel 1201, but instead use the support member 13 within the second accommodating space 102 for cable routing. One or more second brackets 17 can be arranged, and multiple second brackets 17 can be spaced out in different areas of the second accommodating space 102.

[0074] In some embodiments, the first bracket 12 and / or the second bracket 17 may be provided with a plurality of mounting holes for the insertion portion at the bottom of the host or battery pack to pass through.

[0075] The first bracket 12 and the second bracket 17 are located at the bottom of different accommodating spaces in the cabinet 11, providing support for the main unit or battery pack. Mounting holes are provided on the brackets, allowing the connectors at the bottom of the main unit or battery pack to pass through, thus ensuring the main unit or battery pack is securely positioned. Figure 9and Figure 10 As shown, the first bracket 12 is provided with a first mounting hole 1204, such as Figure 12 As shown, the second bracket 17 is provided with a second mounting hole 171. Both the first mounting hole 1204 and the second mounting hole 171 can allow the connector pins at the bottom of the main unit or battery pack to pass through. In practice, the number of mounting holes on different brackets can be two or more. Multiple mounting holes can be arranged in the same direction, or at least some of the multiple mounting holes can be staggered to ensure the stability of the support for the main unit or battery pack.

[0076] Both the first bracket 12 and the second bracket 17 can keep the supported components at a distance from the inner wall of the bottom of the accommodating space, forming a certain space at the bottom of the accommodating space. This facilitates the arrangement of wiring and also helps to form a heat dissipation area to improve the heat dissipation effect.

[0077] Some embodiments of this application also provide an energy storage cabinet, which includes a main unit, multiple battery packs, and the cabinet structure described above. The battery packs are electrically connected to the main unit. The main unit mounting position in the cabinet structure accommodates the main unit, and the battery pack mounting position in the cabinet structure accommodates the battery packs.

[0078] Energy storage cabinets can be used as uninterruptible power supplies (UPS). In containerized energy storage systems used outdoors, the UPS can be installed inside a central cabinet, which can be housed within a shipping container. The main unit within the cabinet controls the charging process of the battery packs and converts the DC power to AC power. Multiple battery packs can be installed in different locations within the cabinet to ensure a sufficient number of packs and increase energy density.

[0079] The energy storage cabinet features a bottom support frame to hold the battery packs or main unit. Multiple rubber feet on the bottom of the battery packs or main unit can be inserted into mounting holes in the bottom support frame. The bottom support frame also has cable routing channels. The cabinet's top-long, bottom-short structure avoids obstructing the cabinet door on the front of the integrated cabinet, which houses components such as the SCU (Small Control Unit). Decorative panels can be installed on the front and rear sides of both the upper and lower sections of the cabinet. The interior of the cabinet can accommodate three battery packs and one main unit arranged in a one-upper-two-bottom configuration, or two battery packs and one main unit arranged in a one-upper-bottom configuration. Specifically, the upper section can accommodate one battery pack and one main unit side-by-side, while the lower section can accommodate one or two battery packs, depending on the specific requirements.

[0080] In the energy storage cabinet, the battery packs can be connected in series, and the front bus of the three battery packs needs to be connected to the rear of the main unit. Bottom supports are installed at the bottom of the upper and lower sections of the cabinet to support the battery packs or main unit, and cable routing holes are provided on the bottom supports. The bottom supports can be connected to the cabinet via multiple connecting lugs.

[0081] like Figure 1 and Figure 2 As shown, the cabinet 11 can be equipped with an upper connector 1103 and a lower connector 1104 on the front side, which are used to connect and fix the cabinet to the integrated cabinet. At the same time, the bottom of the cabinet 11 can also be equipped with a plug-in connector 1105 to form a plug-in hole, so that the forks can be inserted to move the cabinet 11, so as to realize the installation and removal of uninterruptible power supply.

[0082] like Figure 3 and Figure 4 As shown, a reinforcing column, i.e. support 13, can be installed in the middle of the lower part of the cabinet to limit the left and right directions of the battery pack below. The reinforcing column can also fix the wiring harness between the battery pack and the main unit. In this case, the wiring harness does not need to run from the bottom bracket.

[0083] Those skilled in the art will understand that the above embodiments are specific implementations of this application, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this application.
