Description

Technical Field

[0001] This utility model relates to the technical field of energy storage equipment, specifically to an energy storage module and an energy storage device. Background Technology

[0002] In traditional energy storage systems, especially prefabricated containerized energy storage modules, the standardized dimensions of containers limit the layout and energy density of energy storage modules, making it difficult to increase storage capacity per unit area. This means that to meet the ever-increasing demand for energy storage, energy storage stations must occupy more land area, which not only increases project costs but also limits the feasibility of applications in space-constrained environments. Furthermore, as the energy storage capacity of a single prefabricated energy storage module increases, its weight also rises sharply, causing it to exceed transportation limits and increasing transportation costs and difficulties.

[0003] In addition, the existing standardized-size energy storage modules in containers generally adopt a structure that is fixed at the factory to ensure the strength of the structure. However, the current structural setting results in poor flexibility, making it unsuitable for different site environments and inconvenient for later disassembly, maintenance and replacement.

[0004] As can be seen from the above, the energy storage modules in the existing technology are not convenient to be used in the field, have poor flexibility, and the overall structure is limited by transportation. Utility Model Content

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0032] To address the problems of existing energy storage modules being inconvenient to use in field applications, lacking flexibility, and having their overall structure's weight limited by transportation, this application provides an energy storage device that includes one or more energy storage modules.

[0033] Multiple energy storage modules can be stacked along the height direction, or they can be spaced apart or attached to each other on a plane. Setting up multiple energy storage modules helps to increase the energy storage capacity.

[0034] like Figures 1 to 6 As shown, the energy storage module includes multiple energy storage units arranged along the height direction. The multiple energy storage units are connected along the height direction, and each energy storage unit can work independently to form the smallest working unit of this application.

[0035] The energy storage module of this application adopts a structure in which multiple energy storage units are arranged along the height direction to ensure that the multiple energy storage units work together to improve the energy storage capacity of the energy storage module.

[0036] Specifically, the energy storage unit includes a bracket 10, a battery management component 30, and multiple battery packs 20. The bracket 10 has an upper support structure 111 protruding along the height direction on the top side and a lower support structure 112 protruding along the bottom side. The upper support structure 111 and the lower support structure 112 of two adjacent energy storage units are inserted into each other. The two adjacent energy storage units can be supported and fixed by the upper support structure 111 and the lower support structure 112. The multiple battery packs 20 and the battery management component 30 are arranged in the bracket 10 along the length direction of the bracket 10.

[0037] The battery management component 30 is used to manage multiple battery packs 20. The battery management component 30 includes a battery management system and an energy management system.

[0038] In this application, multiple energy storage units are arranged along the height direction of the bracket 10, and the length direction of the bracket 10 is... Figure 1 and Figure 4 As shown in the X direction, the width direction of bracket 10 is... Figure 1 and Figure 4 As shown in the Y direction, the height direction of bracket 10 is... Figure 1 and Figure 4 The Z direction is shown.

[0039] The upper support structure 111 and lower support structure 112 of the energy storage unit in this application can be plugged in to install and fix two adjacent energy storage units. In this way, multiple energy storage units can be stacked and fixed along the height direction of the bracket 10. Therefore, the multiple energy storage units of this application are suitable for on-site installation and fixing, which helps to improve the flexibility of energy storage module installation and use. At the same time, the energy storage module of this application adopts a modular energy storage unit structure, which can be used for on-site installation. Therefore, the energy storage units of this application can be transported independently, avoiding the phenomenon of overweight transportation and reducing transportation difficulty and transportation cost.

[0040] In this embodiment, the energy storage unit further includes high-voltage and low-voltage connection lines. The high-voltage terminals 210 of each battery pack 20 and the high-side terminal of the battery management component 30 are connected via the high-voltage terminal 310 connection line, and the low-voltage terminals 220 of each battery pack 20 and the low-voltage terminal 320 of the battery management component 30 are connected via the low-voltage connection line, wherein the high-voltage and low-voltage terminals are arranged opposite to each other. The battery pack 20 and the battery management component 30 are connected using high-voltage and low-voltage connection lines to facilitate the battery management component 30 in detecting the battery pack 20.

[0041] In this embodiment, the arrangement of the multiple battery packs 20 and the battery management component 30 varies depending on the configuration of each energy storage unit. For example, the battery management component 30 can be positioned between any two battery packs 20 along the length of the bracket 10; or it can be arranged as follows: Figure 1 , Figure 4 and Figure 6 As shown, multiple battery packs 20 are arranged adjacent to each other along the length of the bracket 10, and the battery management component 30 is disposed on one side of the multiple battery packs 20. The arrangement of the multiple battery packs 20 and the battery management component 30 in this application can be configured according to actual needs and practicality.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, along the height direction of the bracket 10, the top end of the bracket 10 abuts against the bottom end of the adjacent bracket 10 above. The two adjacent energy storage units abut against each other through the bracket 10 to realize the stacking structure of the bracket 10, which is conducive to improving the stability of the installation structure of multiple energy storage units.

[0043] Of course, in this application, the top of the bracket 10 and the bottom of the adjacent bracket 10 above it can be spaced apart, in which case the two energy storage units are supported by the upper support structure 111 and the lower support structure 112.

[0044] Specifically, the bracket 10 includes an outer frame, partitions, and a column 110. The outer frame is a cubic structure with a cavity with a front opening. Multiple partitions are provided and spaced apart inside the cavity along the length of the bracket 10. The partitions divide the cavity to form multiple receiving cavities. The battery pack 20 and the battery management component 30 are at least partially disposed inside the receiving cavities.

[0045] Multiple partitions divide the cavity into multiple independent accommodating chambers for independent installation of the battery pack 20 and the battery management system, thereby achieving a modular structural design. This not only facilitates installation and wiring organization but also allows for the independent disassembly, repair, and replacement of individual battery packs 20 or battery management components 30 in the future.

[0046] Along the width direction of the bracket 10, the column 110 is disposed at both ends of the partition and the outer frame. The column 110 extends along the height direction of the bracket 10. The top and bottom ends of the column 110 are respectively disposed at the top and bottom of the outer frame. The top end of the column 110 forms an upper support structure 111, and the bottom end of the column 110 forms a lower support structure 112.

[0047] The upper support structure 111 and lower support structure 112 of the energy storage unit of this application can be disassembled and installed, which facilitates the later maintenance or replacement of the energy storage unit and improves the user experience.

[0048] In this embodiment, each partition and the outer frame are provided with columns 110 on the plate segments that are parallel to and spaced apart from the partition. The structural arrangement of the columns 110 can not only improve the structural strength of the bracket 10, but also the multiple upper support structures 111 and lower support structures 112 formed by the columns 110 can form multiple support points, which is conducive to improving the stability of the connection between energy storage units.

[0049] like Figure 5 As shown, the lower support structure 112 and the upper support structure 111 are arranged in a nested and plugged structure, thereby ensuring that the top surface of one of the brackets 10 of two adjacent energy storage units abuts the bottom surface of the other bracket 10.

[0050] In one embodiment of this application, such as Figure 3 and Figure 5As shown, both the upper support structure 111 and the lower support structure 112 are provided with through holes 113 arranged along the width direction of the bracket 10. After the upper support structures 111 and lower support structures 112 of two adjacent energy storage units are inserted, the through holes 113 on the upper support structures 111 and lower support structures 112 are connected. The energy storage unit also includes fasteners that pass through the through holes 113. The fasteners can be bolts, etc. The fasteners passing through the through holes 113 can be used to fix the upper support structures 111 and lower support structures 112 after they are inserted. When disassembly is required, only the fasteners need to be pulled out, making the overall operation simple.

[0051] In another embodiment of this application, one of the upper support structure 111 and the lower support structure 112 of two adjacent energy storage units has a slot on its outer wall, and the other has a snap-fit ​​protrusion on its inner wall, which snaps into the slot. The upper support structure 111 and the lower support structure 112 are engaged through a snap-fit ​​structure, allowing for simultaneous insertion and fixing. This snap-fit ​​fixing structure facilitates quick installation and disassembly.

[0052] In another embodiment of this application, the upper support structure 111 and lower support structure 112 of two adjacent energy storage units are plugged in and then welded together. Fixing the plugged-in upper support structure 111 and lower support structure 112 by welding helps to ensure the structural strength of the upper support structure 111 and lower support structure 112.

[0053] like Figure 2 As shown, the energy storage unit also includes a first mounting plate 410. Each battery pack 20 along the length of the bracket 10 has a first mounting plate 410 at both ends. The first mounting plate 410 is fixedly connected to the column 110. At least a portion of the first mounting plate 410 is located at the front opening of the accommodating cavity to limit the battery pack 20.

[0054] Specifically, the first mounting plate 410 is used to limit the battery pack 20 to ensure that the battery pack 20 is stably set in the bracket 10. In use, after at least a part of the battery pack 20 is set inside the accommodating cavity, the first mounting plate 410 is fixed to the column 110, and the first mounting plate 410 is used to abut against and limit the battery pack 20, thereby completing the stable setting of the battery pack 20. When it is necessary to remove the battery pack 20, the battery pack 20 can be pulled out simply by removing the first mounting plate 410. The overall operation is simple.

[0055] In this embodiment, the first mounting plate 410 and the column 110 are fixedly connected by fasteners, such as bolts, which make the whole assembly and disassembly convenient and can be quickly disassembled and assembled.

[0056] like Figure 3As shown, the energy storage unit also includes a second mounting plate 420. A second mounting plate 420 is provided at both ends of each battery pack 20 along the length direction of the bracket 10. The second mounting plate 420 is fixedly connected to the bracket 10 and the battery pack 20. The two second mounting plates 420 are symmetrically arranged to ensure that the two ends of the battery pack 20 are subjected to uniform force. The setting of the second mounting plates 420 at both ends ensures the stability of the battery pack 20 installation, which in turn helps to improve the service life of the battery pack 20.

[0057] The second mounting plate 420 includes a first plate segment 421 and a second plate segment 422 that are bent. The first plate segment 421 can be fixedly connected to the column 110 or to the outer frame. The second plate segment 422 is fixedly connected to the battery pack 20. The fixed connection can be achieved by fasteners such as bolts or by welding.

[0058] A second mounting plate 420 is provided at both ends of the battery management component 30 along the length of the bracket 10. The second mounting plate 420 is fixedly connected to the bracket 10 and the battery management component 30. The two second mounting plates 420 are symmetrically arranged to ensure that the forces on both ends of the battery management component 30 are uniform. The setting of the second mounting plates 420 at both ends ensures the stability of the battery management component 30 installation, which in turn helps to improve the efficiency of the battery management component 30.

[0059] The second mounting plate 420 includes a first plate segment 421 and a second plate segment 422 that are bent. The first plate segment 421 can be fixedly connected to the column 110 or to the outer frame. The second plate segment 422 is fixedly connected to the battery management component 30. The fixed connection can be achieved by fasteners such as bolts or by welding.

[0060] In this embodiment, the battery pack 20 and the battery management component 30 of this application are fixedly mounted on the bracket 10 by the second mounting plate 420, thereby enabling the independent assembly and disassembly of the battery pack 20 and the battery management component 30 through the second mounting plate 420. This facilitates the individual repair and replacement of the battery pack 20 and the battery management component 30, improves the convenience and user experience, and reduces structural costs.

[0061] like Figure 5 and Figure 6 As shown, the energy storage module also includes a bottom frame 50, which is disposed at the bottom of multiple energy storage units. The lower support structure 112 of the energy storage unit at the bottom along the height direction of the bracket 10 is supported and fixed to the top surface of the bottom frame 50, and the projection of the energy storage unit along the height direction of the bracket 10 does not exceed the top surface area of ​​the bottom frame 50.

[0062] Specifically, the bottom frame 50 is set at the bottom of multiple energy storage units to support the energy storage units, which helps to ensure the stability of the energy storage unit installation.

[0063] In this embodiment, the bottom frame 50 includes a frame body 510, a hanger 520, and corner pieces 530. The bottom frame 50 has a cubic structure. The lower support structure 112 is fixed to the top surface of the frame body 510. The hanger 520 is telescopically mounted on the frame body 510 along the width direction of the bracket 10. The corner pieces 530 are located at the four bottom corners of the frame body 510.

[0064] The boom 520 is used to facilitate the hoisting of the mobile energy storage module. The boom 520 is retractable, which allows it to be extended when in use and retracted when not in use, thus avoiding the occupation of extra space.

[0065] The corner pieces 530 are located at the four bottom corners of the frame body 510. They not only provide protection, but also help ensure the stability of the structure and prevent deviation or tilting.

[0066] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0067] The energy storage module of this application adopts a structure in which multiple energy storage units are arranged along the height direction to ensure that the multiple energy storage units cooperate to improve the energy storage capacity of the energy storage module. The upper support structure 111 and the lower support structure 112 of the energy storage unit of this application can be plugged in to install and fix two adjacent energy storage units. Thus, multiple energy storage units can be stacked and fixed along the height direction of the bracket 10. Therefore, the multiple energy storage units of this application are suitable for on-site installation and fixing, which helps to improve the flexibility of the installation and use of the energy storage module. At the same time, the energy storage module of this application adopts a modular energy storage unit structure, which can be used for on-site installation. Therefore, the energy storage units of this application can be transported independently, avoiding the phenomenon of overweight transportation and reducing transportation difficulty and transportation costs.

[0068] The upper support structure 111 and lower support structure 112 of the energy storage unit of this application can be disassembled and installed, which facilitates the later maintenance or replacement of the energy storage unit and improves the user experience.

[0069] The battery pack 20 and battery management component 30 of this application are mounted on the bracket 10 via the second mounting plate 420, thereby enabling independent assembly and disassembly of the battery pack 20 and battery management component 30 via the second mounting plate 420.
