Description

Technical Field

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

[0002] As a crucial unit within energy storage equipment, the combiner cabinet provides emergency backup power to critical components such as communication and control systems through its internal uninterruptible power supply (UPS). Currently, combiner cabinets typically contain one UPS and multiple battery packs, with the UPS and battery packs connected in series to form a power supply circuit.

[0003] The existing combiner cabinet adopts a double-sided maintenance design, that is, the front and rear sides of the combiner cabinet are equipped with openable doors: the front side is used for maintaining and operating the UPS panel, and the rear side is used for maintaining the battery pack switches and wiring ports.

[0004] However, existing combiner cabinets require reserved maintenance space at both the front and back to meet the maintenance needs of the UPS panel and battery pack respectively, resulting in a high space occupancy rate of the combiner cabinets. Utility Model Content

[0005] This application provides a combiner cabinet and energy storage device, which helps to reduce the space occupancy rate of the combiner cabinet.

[0006] In a first aspect, this application provides a combiner cabinet for an energy storage device, comprising: a cabinet body defining a receiving cavity, the cabinet body having an opening on one side along a first direction for opening and closing the receiving cavity, the receiving cavity including a battery mounting area and an electrical control area spaced apart along a second direction, the battery mounting area including a plurality of battery mounting positions; a battery pack corresponding to each of the battery mounting positions, the battery pack being removably disposed at the corresponding battery mounting position, the battery pack having an interface side, the interface side having a first connection port, the interface side being disposed facing the opening; a UPS main control device disposed in the electrical control area, the UPS main control device having an operation panel on the side facing the opening, the UPS main control device having a second connection port on the side facing away from the opening; and a connecting cable connecting the first connection ports of the plurality of battery packs on the interface side, extending from the gap between the electrical control area and the battery mounting area to the side of the UPS main control device facing away from the opening and connecting to the second connection port.

[0007] In one possible implementation, the combiner cabinet further includes: a plurality of guide rails corresponding one-to-one with the battery mounting positions, the guide rails being fixed to the bottom wall of the corresponding battery mounting positions, the guide rails extending along the first direction, and the battery pack being slidably disposed on the corresponding guide rails along the first direction.

[0008] In one possible implementation, the guide rail includes: a base plate extending along the first direction and fixed to the bottom wall of the mounting position, wherein the battery pack is disposed on the base plate; and a guide plate perpendicularly disposed on one side edge of the base plate along the second direction, the guide plate being used to guide the corresponding battery pack.

[0009] In one possible implementation, among the plurality of guide rails arranged along the second direction, the guide rail closest to the UPS main control device is the end guide rail. Except for the battery pack on the end guide rail, each battery pack is located between the guide plates of two adjacent guide rails. The combiner cabinet further includes an auxiliary bracket, which is disposed in the gap between the electrical control area and the battery installation area. The battery pack on the end guide rail is located between the auxiliary bracket and the guide plate of the end guide rail.

[0010] In one possible implementation, the guide rail further includes a limiting plate disposed at one end of the substrate away from the opening along the first direction, the limiting plate being used to limit the battery pack.

[0011] In one possible implementation, a rear frame is provided on the side of the receiving cavity opposite to the opening, and a fixing plate is fixedly provided on the battery pack. The fixing plate includes a hanging ear, which extends along the second direction to the battery mounting position adjacent to the battery pack and is located on the side of the limiting plate of the adjacent guide rail facing away from the opening. The hanging ear is used to connect with the rear frame.

[0012] In one possible implementation, the fixing plate further includes a plurality of connecting side plates, any two of which are perpendicular to each other, and the plurality of connecting side plates are respectively connected to different surfaces of the battery pack.

[0013] In one possible implementation, the combiner cabinet further includes a baffle plate disposed on the side of the battery mounting position facing the opening, the baffle plate being connected to the cabinet body, and the baffle plate engaging with the battery pack along the first direction.

[0014] In one possible implementation, the cabinet includes: an outer frame defining the opening; and multiple sets of beams spaced vertically apart, with adjacent sets of beams defining the receiving cavity, the beams located at the bottom of the receiving cavity forming the bottom wall of the battery mounting position.

[0015] Secondly, this application provides an energy storage device, including a combiner cabinet as described in any of the above possible implementations.

[0016] The combiner cabinet and energy storage equipment provided in this application have an integrated layout for battery pack installation and maintenance, UPS operation, and power supply circuit cable connection by setting the interface side of the battery pack and the operation panel of the UPS main control device to face the same side of the cabinet. At the same time, the connecting lines are laid out by utilizing the gap between the electrical control area and the battery installation area. This effectively solves the problem of reserving operating space on both sides in the traditional double-sided maintenance design of combiner cabinets. It not only reduces the space occupation rate of the combiner cabinet in the application scenario, but also improves the convenience of maintenance through the removable battery pack design and optimized cable path.

[0033] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] Existing combiner cabinets employ a double-sided maintenance design, meaning that both the front and rear sides of the cabinet have openable doors: the front side is for maintaining and operating the UPS panel, and the rear side is for maintaining the battery pack switches and wiring ports. However, existing combiner cabinets require reserved maintenance space at both the front and rear to meet the maintenance needs of the UPS panel and battery pack respectively, resulting in a high space occupancy rate for the combiner cabinet.

[0036] In view of this, this application provides a combiner cabinet and energy storage device. By setting the interface side of the battery pack and the operation panel of the UPS main control device to face the same side of the cabinet, and by using the gap between the electrical control area and the battery installation area to lay the connecting lines, a single-sided integrated layout for battery pack installation and maintenance, UPS operation and power supply circuit cable connection is realized. This effectively solves the problem of reserving operating space on both sides in the traditional double-sided maintenance design of combiner cabinets. It not only reduces the space occupation rate of the combiner cabinet in the application scenario, but also improves the convenience of maintenance through the removable battery pack design and optimized cable path.

[0037] It is understandable that energy storage devices can be distributed energy storage devices, containerized energy storage devices, mobile energy storage devices, etc.

[0038] For ease of description, the first direction can refer to the X direction. The second direction can refer to the Y direction.

[0039] The following is for reference. Figures 1-4The combiner cabinet 1 provided in this embodiment includes a cabinet 10, a battery pack 20, a UPS main control device 30, and connecting cables. The cabinet 10 serves as an overall frame, providing mechanical support. A receiving cavity 11 is defined within the cabinet 10. The cabinet 10 has an opening. Specifically, the opening is located on one side of the cabinet 10 along a first direction to open and close the receiving cavity 11. A battery mounting area and an electrical control area are provided within the receiving cavity 11. The battery mounting area provides standardized mounting positions for multiple battery packs 20, ensuring stable fixation of the battery packs 20 and forming a modular layout. The electrical control area can house the UPS main control device 30, responsible for converting the DC power from the battery packs 20 into AC power (or maintaining DC output), providing stable and uninterrupted power to external loads. The battery mounting area and the electrical control area can be arranged at intervals along a second direction within the receiving cavity 11. The battery mounting area includes multiple battery mounting positions.

[0040] In one possible implementation, refer to Figure 1 The cabinet 10 includes an outer frame 13 and crossbeams 14. The outer frame 13 defines an opening. The crossbeams 14 can be multiple sets spaced vertically. Thus, a receiving cavity 11 can be defined between two adjacent sets of crossbeams 14. The crossbeams 14 located at the bottom of the receiving cavity 11 can form the bottom wall of the battery mounting position.

[0041] Furthermore, the battery pack 20 is disposed within the battery mounting area and corresponds one-to-one with the battery mounting positions. The battery pack 20 is removably disposed in the corresponding battery mounting position. The battery pack 20 has an interface side. The interface side is provided with an opening facing the cabinet 10. The interface side is provided with a first connection port 21. The first connection port 21 can transmit the electrical energy stored in the battery pack 20 to the UPS main control device 30 through a connection line to form a complete power supply circuit.

[0042] The UPS main control unit 30 is located in the electrical control area. An operation panel 31 is provided on one side of the UPS main control unit 30. The operation panel 31 faces the opening of the cabinet 10. That is, the operation panel 31 of the UPS main control unit 30 and the first connection port 21 of the battery pack 20 are located on the same side. A second connection port 32 is provided on the side of the UPS main control unit 30 facing away from the opening. Connecting cables can connect multiple battery packs 20 to their first connection ports 21 on the interface side. Furthermore, after connecting multiple battery packs 20 to their first connection ports 21, the connecting cables can extend from the gap between the electrical control area and the battery mounting area to the side of the UPS main control unit 30 facing away from the opening and connect to the second connection port 32 to form a closed loop.

[0043] Understandably, by setting the interface side of the battery pack 20 and the operation panel 31 of the UPS main control device 30 to face the same side of the cabinet 10, and by using the gap between the electrical control area and the battery installation area to lay the connecting lines, a single-sided integrated layout for battery pack 20 installation and maintenance, UPS operation and power supply circuit cable connection is achieved. This effectively solves the problem of reserving operating space on both sides in the traditional double-sided maintenance design of combiner cabinets. It not only reduces the space occupation rate of combiner cabinet 1 in the application scenario, but also improves the convenience of maintenance through the removable design of battery pack 20 and the optimization of cable path.

[0044] In one possible implementation, refer to Figure 4 The combiner cabinet 1 also includes guide rails 40. Multiple guide rails 40 correspond one-to-one with the battery mounting positions. The guide rails 40 are fixed to the bottom wall of the corresponding battery mounting position. Furthermore, the guide rails 40 extend along a first direction so that the battery pack 20 can be slidably mounted on the corresponding guide rail 40 along the first direction. Optionally, guide grooves or protrusions may be added to the surface of the guide rails 40 to match the grooves or rollers on the bottom of the battery pack 20, ensuring that the battery pack 20 can move linearly along the first direction during sliding, avoiding offset or jamming.

[0045] Understandably, by setting guide rails 40 that correspond one-to-one with the battery mounting positions, the battery pack 20 can be slidably pulled out along the first direction, improving the installation and maintenance efficiency of the battery pack 20. Furthermore, the extension layout of the guide rails 40 along the first direction is highly coordinated with the single-sided opening maintenance design of the cabinet 10, achieving a balance between dense battery pack arrangement and convenient maintenance within a limited volume, providing reliable hardware support for the deployment of the energy storage system.

[0046] In one possible implementation, refer to Figure 6 The guide rail 40 includes a base plate 41 and a guide plate 42. The base plate 41 extends along a first direction and is fixed to the bottom wall of the mounting position. The base plate 41 supports the battery pack 20, allowing the battery pack 20 to be mounted on the base plate 41. The guide plate 42 is vertically disposed on one side of the base plate 41. Specifically, the guide plate 42 is vertically disposed on one edge of the base plate 41 along a second direction. The guide plate 42 guides the corresponding battery pack 20. Optionally, the bottom surface of the base plate 41 may have longitudinal reinforcing ribs that extend along the first direction and engage with grooves in the bottom wall of the battery mounting position to enhance the bending resistance of the guide rail 40. Simultaneously, bolts are used to fix the base plate 41 through the bottom to prevent exposed screws from interfering with the sliding of the battery pack 20.

[0047] It is understandable that by extending the substrate 41 along the first direction and fixing it to the bottom wall of the mounting position, a stable bearing base can be provided for the battery pack 20, ensuring its stability in a vibration environment; the guide plate 42 is vertically arranged on the second direction side edge of the substrate 41 to form a single-sided guide channel, which can limit the sliding trajectory of the battery pack 20 along the first direction, avoid deviation or jamming, and at the same time reduce friction loss by simplifying the guide contact surface.

[0048] In one possible implementation, refer to Figure 4 Within the battery mounting area, multiple guide rails 40 are arranged adjacently. Specifically, the multiple guide rails 40 are arranged adjacently along a second direction. Among them, the guide rail 40 closest to the UPS main control unit 30 can be the end guide rail. In the specific implementation, except for the battery pack 20 on the end guide rail, each battery pack 20 located on the other guide rails 40 is positioned between guide plates 42 of two adjacent guide rails 40, with the two guide plates 42 used to improve the stability of the battery pack 20 along the second direction.

[0049] Furthermore, to ensure stable installation of the battery pack 20 on the end rail, the combiner cabinet 1 also includes an auxiliary bracket 50. The auxiliary bracket 50 is positioned in the gap between the electrical control area and the battery installation area. This allows the battery pack 20 on the end rail to be positioned between the auxiliary bracket 50 and the guide plate 42 of the end rail, thus achieving stable installation. Optionally, the auxiliary bracket 50 can be an L-shaped bracket. The auxiliary bracket 50 is bolted to the crossbeam 14 of the outer frame 13 of the cabinet 10. The vertical side of the auxiliary bracket 50 can be parallel to the guide plate 42 of the end rail, and the horizontal side can extend in a second direction to the vicinity of the UPS main control device 30.

[0050] Understandably, the auxiliary bracket 50, in conjunction with the guide plate 42 of the end guide rail, provides bidirectional clamping support for the battery pack 20 on the end guide rail, enabling it to achieve the same dual-sided limiting effect in the second direction as the intermediate battery pack 20, thus solving the problem of easy loosening on one side. The auxiliary bracket 50 fills the gap between the electronic control area and the battery installation area, forming a rigid support structure, thereby effectively limiting the lateral movement of the end battery pack 20 and dispersing the concentrated load of the battery pack 20 on the guide rail 40, preventing deformation of the cabinet 10. The design of the auxiliary bracket 50 improves the vibration resistance stability of the overall structure without requiring additional space inside the cabinet.

[0051] In one possible implementation, refer to Figure 6 The guide rail 40 also includes a limiting plate 43. The limiting plate 43 may be disposed at one end of the substrate 41 along the first direction. Specifically, the limiting plate 43 may be disposed at the end of the substrate 41 away from the opening along the first direction for limiting the battery pack 20.

[0052] Understandably, by setting the limiting plate 43, a rigid stop can be provided for the battery pack 20 along the first direction, preventing excessive displacement or detachment from the guide rail 40 when the battery pack 20 is pushed in. At the same time, the limiting plate 43, guide plate 42, and auxiliary bracket 50 together form a multi-dimensional limiting structure, enabling the battery pack 20 to maintain stability in multiple directions under vibration, avoiding displacement or shaking caused by unilateral force. In addition, the integrated design of the limiting plate 43 and the base plate 41 simplifies the installation process and does not require additional cabinet space, ensuring vibration resistance while retaining the convenient maintenance feature of pulling the battery pack 20 along the guide rail 40.

[0053] In one possible implementation, refer to Figures 2-4 A rear frame 12 is provided within the receiving cavity 11. The rear frame 12 is positioned opposite the opening of the cabinet 10. The rear frame 12 is used to fix and connect the battery pack 20. Specifically, a fixing plate 22 is fixedly provided on the battery pack 20. The fixing plate 22 includes a hanging ear 221. The hanging ear 221 can extend along a second direction to the battery mounting position adjacent to the battery pack 20 and connect to the rear frame 12. Furthermore, the hanging ear 221 can be located on the side of the limiting plate 43 of the adjacent guide rail 40 facing away from the opening. That is, the hanging ear 221 can be located between the limiting plate 43 and the rear frame 12. Optionally, the hanging ear 221 can be an L-shaped bent plate, with its vertical side fixed to the fixing plate 22 of the battery pack 20 by bolts, and its horizontal side extending to a preset connection hole of the rear frame 12, and rigidly connected to the rear frame 12 by a locking nut.

[0054] Understandably, by extending the hook 221 along the second direction to the adjacent battery mounting position and connecting it to the rear frame 12, the fixing point of the battery pack 20 is transferred to the rear frame 12. The rigid support of the rear frame 12 enables cross-regional fixing, enhancing the battery pack 20's resistance to lateral displacement in the second direction. Simultaneously, the hook 221 is located between the limiting plate 43 and the rear frame 12, allowing the limiting plate 43 to prevent the battery pack 20 from moving backward while simultaneously forming a bidirectional constraint with the hook 221, limiting the battery pack 20's displacement along the first direction and preventing loosening caused by vibration and impact.

[0055] In one possible implementation, refer to Figure 5 , Figure 7 The fixing plate 22 also includes a plurality of connecting side plates 222. Any two of the plurality of connecting side plates 222 are perpendicular to each other. The plurality of connecting side plates 222 are respectively connected to different surfaces of the battery pack 20.

[0056] It is understandable that by attaching the multi-directional vertical connecting side plate 222 to the battery pack 20, the battery pack 20 can be provided with limiting support, suppressing the multi-degree-of-freedom displacement of the battery pack 20 under complex working conditions (such as tilting and warping), and ensuring its stable load-bearing on the guide rail 40.

[0057] In one possible implementation, refer to Figure 2 , Figure 4 The combiner cabinet 1 also includes a baffle 60. The baffle 60 is located on the side of the battery mounting position facing the opening. The baffle 60 can be connected to the cabinet body 10. Alternatively, the baffle 60 can also be connected to the end of the guide rail 40 near the opening. In this way, after the battery pack 20 is installed in the battery mounting position, the baffle 60 and the battery pack 20 can be engaged in a stop-locking action in a first direction.

[0058] Furthermore, this application also provides an energy storage device, including the aforementioned combiner cabinet 1.
