Description

Technical Field

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

[0002] Currently, marine energy storage systems are mostly arranged in battery clusters within the engine room. A typical marine battery cluster mainly consists of an open frame structure made of profiles. Battery modules are sequentially installed on multi-layer brackets of the frame. Their electrical connections (such as busbars and high-voltage harnesses), the data acquisition harnesses of the battery management system, and communication lines are usually located on the front or side of the battery cluster for easy installation and maintenance.

[0003] In practical applications and large-scale deployments, it has been found that this open battery cluster structure design directly exposes live components such as high-voltage electrical interfaces and cable connection points, posing a significant risk of accidental contact and potentially causing electric shock accidents. Furthermore, it is easily loosened or damaged by human pulling, affecting the stability of signal acquisition and the reliability of electrical connections. Additionally, the high humidity on board makes it difficult for this open structure to effectively resist the intrusion of dust and moisture, potentially reducing insulation performance, increasing the risk of creepage, and affecting the long-term stability of the system.

[0004] Therefore, there is an urgent need to propose a battery cluster and energy storage system to solve the above-mentioned technical problems. Utility Model Content

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0053] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 this utility model based on the specific circumstances.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0055] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0056] This embodiment provides a battery cluster that can reliably protect live components such as high-voltage electrical interfaces and cable connection points, thereby improving the stability and safety of system operation.

[0057] Specifically, such as Figures 1-3 As shown, the battery cluster includes a frame 100, a high-voltage box 200, multiple battery packs 300, and a protective cover 400.

[0058] The frame 100 includes a frame body 110, a first bracket 120 disposed at the top of the frame body 110, and a plurality of second brackets 130 disposed below the first bracket 120. A high-voltage box 200 is disposed on the first bracket 120. Battery packs 300 are disposed one-to-one with the second brackets 130, with each second bracket 130 hosting one battery pack 300. Electrical connection components for the battery packs 300 and the high-voltage box 200 are centrally located on the front of the frame body 110. A protective cover 400 is detachably disposed on the front of the frame body 110, and the protective cover 400 includes a plurality of sub-covers 410 sequentially arranged along the height direction of the frame body 110, the plurality of sub-covers 410 being spliced ​​together.

[0059] The battery cluster centrally houses the electrical connection components for the high-voltage box 200 and multiple battery packs 300 on the front of the frame 110 of the frame 100, with a protective cover 400 covering the front of the frame 110. This protective cover 400 isolates the electrical connection components from the external environment, effectively preventing accidental contact by maintenance personnel during inspections or nearby operations, significantly improving the operational safety and electrical connection reliability of the battery cluster. Furthermore, it effectively reduces the risk of short circuits caused by small metal parts such as screws or wire ends accidentally falling between the high-voltage positive and negative terminals. Additionally, it effectively resists the intrusion of dust and moisture, thereby improving the operational stability of the battery cluster. The protective cover 400 comprises multiple sub-covers 410 arranged sequentially along the height of the frame 110, allowing operators to remove only the corresponding sub-covers 410 during maintenance. Compared to the previous method of disassembling the entire protective cover 400, this design offers greater flexibility, reduces maintenance difficulty, and improves maintenance efficiency. Moreover, this modular structure of the protective cover 400 facilitates manufacturing, thereby reducing production costs. The multiple sub-covers 410 are connected by splicing, which eliminates the need for a connection structure between the sub-covers 410 and further reduces the processing and installation difficulty of the sub-covers 410.

[0060] Understandably, the front of frame 110 refers to the maintenance side of the battery cluster.

[0061] Further, see also Figure 2 Two adjacent battery packs 300 are electrically connected via a conductive busbar 500. This configuration is simpler and more organized than the existing technology that uses cables to connect two adjacent battery packs 300.

[0062] Optionally, see [link to relevant documentation] Figure 3The multiple sub-covers 410 include a first sub-cover corresponding to the high-voltage box 200 and multiple second sub-covers corresponding to multiple battery packs 300. This configuration allows for targeted repairs of the high-voltage box 200 by individually removing the first sub-cover when it malfunctions. Similarly, if a battery pack 300 malfunctions, the corresponding second sub-cover can be removed individually, improving maintenance convenience.

[0063] Further, see also Figure 3 In one possible embodiment, an indicator light 411 is provided on the first sub-cover. By providing the indicator light 411 on the first sub-cover, the operating status of the high-voltage box 200 can be quickly understood.

[0064] Optionally, to increase the visibility of indicator light 411, a border of a different color from the first sub-cover, such as dark gray, can be set around indicator light 411 to quickly capture the status of indicator light 411.

[0065] Optionally, see [link to relevant documentation] Figure 3 Multiple second sub-covers can be configured with identical structures and dimensions. This configuration facilitates modular manufacturing, reduces manufacturing costs, and improves manufacturing efficiency.

[0066] Further, see also Figure 3 The second sub-protective cover has gripping parts 412 on opposite sides, allowing operators to install or remove it. In other words, by providing gripping parts 412, the difficulty of installing and removing the second sub-protective cover is reduced.

[0067] Alternatively, gripping parts 412 may be provided on opposite sides of the first sub-cover. Since the high-voltage box 200 has a low failure rate, the first sub-cover does not need to be disassembled frequently. Considering the manufacturing cost, gripping parts 412 may not be provided on the first sub-cover.

[0068] Furthermore, such as Figure 3 and Figure 4As shown, on the front of the frame 110, multiple first connectors 111 are provided on opposite sides of the frame 110, with each first connector 111 corresponding to a gripping part 412. One end of each first connector 111 is connected to the frame 110, and the other end has a first connecting hole 1111. The gripping part 412 includes a gripping groove 4121, which corresponds to the first connector 111. A first through hole is provided on the groove wall of the gripping groove 4121 near the first connector 111, and a first fastener passes through the first through hole and connects to the first connecting hole 1111. The second sub-cover is connected to the frame 110 through the cooperation of the first fastener, the first through hole, and the first connecting hole 1111. The structure is simple and facilitates the installation and removal of the second sub-cover. Furthermore, the gripping groove 4121 can also hide the first fastener, which helps to improve the overall aesthetics of the battery cluster.

[0069] Optionally, in one possible embodiment, the first fastener can be a bolt, and correspondingly, the first connecting hole 1111 is a threaded hole. In other possible embodiments, the structure of the first fastener can also be configured differently, depending on actual needs, and this application does not impose specific limitations.

[0070] Optionally, beveled surfaces for transition can be provided on opposite sides of the protective cover 400. On the one hand, this can reduce the risk of operators being injured by sharp corners; on the other hand, it can improve the overall aesthetics of the protective cover 400.

[0071] Optionally, a recessed portion can be provided on the front of the protective cover 400. This design can increase the three-dimensionality of the protective cover 400 and further improve its overall aesthetics.

[0072] Furthermore, such as Figures 4-6 As shown, the first bracket 120 has a second connector 121 on the side near the front of the frame 110, and the second connector 121 has a second through hole. The first bracket 120 has a first positioning pin 122 on the side near the back of the frame 110. The high-voltage box 200 has a first positioning hole 210 on the back, which is inserted into the first positioning pin 122. The high-voltage box 200 has a second connecting hole 220 on the front, and a second fastener 123 passes through the second through hole and connects to the second connecting hole 220.

[0073] The installation method for the high-voltage box 200 is as follows:

[0074] First, place the back side of the high-voltage box 200 on the first bracket 120;

[0075] Then, push the high-pressure box 200 so that the first positioning hole 210 is inserted into the first positioning pin 122;

[0076] Finally, the second fastener 123 is inserted through the second through hole and connected to the second connecting hole 220.

[0077] The cooperation between the first positioning pin 122 and the first positioning hole 210 can not only position the high-voltage box 200, facilitating the installation of the second fastener 123, but also restrict the displacement of the high-voltage box 200 along the height direction of the frame 110, thereby improving the stability of the high-voltage box 200 installation. The structure is simple and easy to install.

[0078] Optionally, first positioning holes 210 can be provided on both opposite sides of the back of the high-voltage box 200, and correspondingly, two first positioning pins 122 corresponding to the two first positioning holes 210 can be provided on the side of the first bracket 120 near the back of the frame 110. Alternatively, second connecting holes 220 can be provided on both opposite sides of the front of the high-voltage box 200, and correspondingly, two second connecting pieces 121 corresponding to the two second connecting holes 220 can be provided on the side of the first bracket 120 near the front of the frame 110. This arrangement can improve the stability of the high-voltage box 200 during installation.

[0079] It is understandable that the front of the high-voltage box 200 and the front of the frame 110 are the same side.

[0080] Understandably, the front of the high-voltage box 200 typically integrates input / output connectors, communication and data transmission interfaces, a display, operation buttons, a handle, etc.

[0081] Understandably, the second fastener 123 is optional but not limited to a bolt.

[0082] Furthermore, such as Figure 4 , Figure 7 and Figure 8 As shown, the second bracket 130 has a third connector 131 on the side near the front of the frame 110, and the third connector 131 has a third through hole. The second bracket 130 has a second positioning pin 132 on the side near the back of the frame 110. The battery pack 300 has a second positioning hole 310 on the back, which is inserted into the second positioning pin 132. The battery pack 300 has a third connecting hole 320 on the front, and a third fastener 133 passes through the third through hole and connects to the third connecting hole 320.

[0083] The installation method for the 300 battery pack is as follows:

[0084] First, place the back side of the battery pack 300 on the corresponding second bracket 130;

[0085] Then, push the battery pack 300 so that the second positioning hole 310 is inserted into the second positioning pin 132;

[0086] Finally, the third fastener 133 is inserted through the third through hole and connected to the third connecting hole 320.

[0087] The cooperation between the second positioning pin 132 and the second positioning hole 310 can not only position the battery pack 300 to facilitate the installation of the third fastener 133, but also limit the displacement of the battery pack 300 along the height direction of the frame 110, thereby improving the stability of the battery pack 300 installation. The structure is simple and easy to install.

[0088] It is understandable that the front of the battery pack 300 and the front of the frame 110 are the same side.

[0089] Optionally, second positioning holes 310 can be provided on both opposite sides of the back of the battery pack 300, and correspondingly, two second positioning pins 132 corresponding to the two second positioning holes 310 can be provided on the side of the second bracket 130 near the back of the frame 110. Alternatively, third connecting holes 320 can be provided on both opposite sides of the front of the battery pack 300, and correspondingly, two third connectors 131 corresponding to the two third connecting holes 320 can be provided on the side of the second bracket 130 near the front of the frame 110. This arrangement can improve the stability of the battery pack 300 installation.

[0090] Optionally, the battery pack 300 uses small-capacity cells. This configuration helps reduce the overall weight of the battery pack.

[0091] Understandably, the third fastener 133 is optional but not limited to a bolt.

[0092] Optionally, such as Figure 1 and Figure 2 As shown, multiple second brackets 130 are spaced apart along the height direction of the frame 110 to form at least one row of bracket groups. This arrangement makes the multiple battery packs 300 more regularly arranged, facilitating installation and maintenance.

[0093] Furthermore, such as Figure 2 , Figure 9 and Figure 10 As shown, multiple second brackets 130 are spaced apart along the height direction of the frame 110 to form two rows of bracket groups. That is, multiple battery packs 300 are spaced apart along the height direction of the frame 110 to form two rows. The coolant inlet of the battery pack 300 on each row of bracket groups is close to the side of the frame 110, and the coolant outlet of the battery pack 300 on each row of bracket groups is close to the center of the frame 110.

[0094] The battery pack also includes a liquid cooling system 600, which comprises a coolant inlet manifold 610, coolant inlet branch pipes 620, a coolant outlet manifold 630, and coolant outlet branch pipes 640. The coolant inlet manifold 610 is located at the bottom of the front side of the frame 110. The coolant inlet branch pipes 620 are located at both ends of the coolant inlet manifold 610, respectively on opposite sides of the frame 110, and extend along the height of the frame 110. Multiple coolant inlet branch pipes 621 are provided on the coolant inlet branch pipes 620, each corresponding to a row of battery packs 300, and are connected to the coolant inlet of its corresponding battery pack 300. The coolant outlet manifold 630 is located at the bottom of the front side of the frame 110. The coolant output branch pipe 640 is located in the middle of the coolant output main pipe 630 and in the middle of the frame 110, extending along the height of the frame 110. Multiple coolant output branch pipes 641 are provided on the coolant output branch pipe 640, each corresponding to one of the two battery packs 300, and connected to the coolant outlet of the corresponding battery pack 300.

[0095] The liquid cooling system 600 adopts a shared coolant output branch pipe 640 for two battery packs 300, which simplifies the structure, improves the simplicity of the battery pack piping connection, and reduces the difficulty of installation and maintenance of the battery pack.

[0096] Optionally, see [link to relevant documentation] Figure 3 The multiple sub-shrouds 410 also include a third sub-shroud corresponding to the coolant inlet manifold 610 and the coolant outlet manifold 630 to protect the coolant inlet manifold 610 and the coolant outlet manifold 630.

[0097] Optionally, in one possible embodiment, both ends of the coolant inlet manifold 610 are provided with coolant inlets, and both ends of the coolant outlet manifold 630 are provided with coolant outlets. This arrangement helps to improve the heat exchange efficiency of the liquid cooling system 600, thereby improving the cooling effect on the battery pack 300.

[0098] Furthermore, such as Figure 8 As shown, on the front of the frame 110, multiple fourth connectors 140 are provided on opposite sides of the frame 110, and the coolant inlet branch pipe 620 is snapped into the fourth connectors 140. The coolant inlet branch pipe 620 is fixed by snapping the fourth connectors 140 into it, which is simple in structure and easy to assemble.

[0099] Alternatively, in one possible embodiment, the fourth connector 140 is U-shaped.

[0100] Optionally, in one possible embodiment, the fourth connector 140 and the first connector 111 are the same part. This configuration simplifies the components of the battery cluster, helps to reduce the cost of the battery cluster, and facilitates the installation of the battery cluster.

[0101] Furthermore, multiple fifth connectors (not shown in the figure) can be provided on the front of the frame 110, in the middle of the frame 110, and the coolant output branch pipe 640 is snapped into the fifth connectors. The coolant output branch pipe 640 is fixed by snapping the fifth connectors into it, which is simple in structure and easy to assemble.

[0102] Optionally, the coolant inlet main 610 and coolant outlet main 630 can be controlled by shut-off valves. The coolant inlet branch pipe 621 and coolant outlet branch pipe 641 can be controlled by ball valves.

[0103] This embodiment also provides an energy storage system, including at least one of the above-described battery clusters.

[0104] Because of the use of the aforementioned battery clusters, this energy storage system exhibits high stability and safety during operation.

[0105] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
