Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a battery assembly structure for a household energy storage device. Background Technology

[0002] Existing home energy storage devices typically involve directly installing individual battery cells inside the storage box. This method has several drawbacks: installing each battery cell individually into the box is cumbersome due to limited space. Furthermore, existing energy storage devices often lack effective securing structures for the batteries, making them prone to movement during transportation and use, thus affecting battery lifespan. While some energy storage devices use steel straps to secure the batteries, this method is not only inconvenient to install but also susceptible to damage from improper strapping.

[0003] Therefore, there is an urgent need for a battery assembly structure for home energy storage devices that is structurally sound, has high assembly efficiency, and can securely fix the battery. Utility Model Content

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] Please also refer to Figures 1-7The battery assembly structure of the household energy storage device provided in this embodiment includes a module box 10. The module box 10 includes a surrounding plate 11 and a sealing plate 12. The surrounding plate 11 encloses a top-through receiving space. A partition 13 is provided in the receiving space, dividing the receiving space into a first cavity 14 and a second cavity 15. Battery modules 20 are respectively provided in the first cavity 14 and the second cavity 15. Each battery module 20 includes multiple batteries 21 arranged along the length direction of the receiving space. One end of the receiving space is open. The sealing plate 12 is provided at the opening and can move relative to the surrounding plate 11 along the length direction of the receiving space so that the sealing plate 12 abuts against each battery module 20 and is fixedly connected to the surrounding plate 11.

[0035] In this embodiment, the enclosure 11 forms a receiving space for accommodating the battery module 20, with the top of the receiving space extending upwards. A partition 13 is vertically arranged within the receiving space, dividing the receiving space into a first cavity 14 and a second cavity 15 that are adjacent in the horizontal direction.

[0036] In a specific implementation, the module box 10 contains two independent battery modules 20, including a first battery module 22 disposed in the first cavity 14 and a second battery module 23 disposed in the second cavity 15. Each battery module 20 includes multiple batteries 21 arranged along the length of the containing space, and these batteries 21 are arranged sequentially to form a complete battery module 20.

[0037] The receiving space has an open end, and a sealing plate 12 is disposed at this open end. The sealing plate 12 is movable relative to the surrounding plate 11 along the length of the receiving space. The purpose of this movable design is to enable the sealing plate 12 to accurately abut against the battery module 20. By adjusting the position of the sealing plate 12, appropriate pressure can be applied to the battery module 20, thereby fixing the battery module 20. After the sealing plate 12 moves to the appropriate position, it is fixedly connected to the surrounding plate 11, thus completing the entire process of fixing the battery module 20.

[0038] In the actual installation process, the batteries 21 are first placed into the first cavity 14 and the second cavity 15 formed by the partition 13 according to a predetermined arrangement, forming the first battery module 22 and the second battery module 23 respectively. Then, the sealing plate 12 is inserted from the opening end of the receiving space and pushed to move along the receiving space towards the two battery modules 20. When the sealing plate 12 moves to the predetermined position, appropriate pressure is applied to the two battery modules 20 simultaneously, so that the adjacent batteries 21 are tightly fitted together. Then, the sealing plate 12 is fixedly connected to the surrounding plate 11. In this way, the two battery modules 20 can be firmly fixed in the module box 10, effectively preventing the batteries 21 from shaking during use.

[0039] This structural design offers several advantages: First, because the top of the housing is open, operators can directly insert and position the battery 21 from the top without considering size limitations at the opening or interference from other electrical components within the energy storage box. This simplifies the assembly process of the battery module 20 and improves assembly efficiency. Second, the partition 13 divides the housing into two independent cavities, facilitating group management of the battery modules 20. Furthermore, the sealing plate 12, by moving within the housing, can control the pressure applied to the battery module 20. Combined with its fixed connection to the surrounding plate 11, this forms a complete constraint, avoiding the problems of uneven or excessive pressure that can lead to damage from traditional bundling methods, thus achieving reliable fixation of the battery module 20.

[0040] In this embodiment, after the module box 10 is assembled, it is placed entirely in the energy storage box 80, which enables the rapid installation of the battery module 20.

[0041] In this embodiment, the predetermined position refers to the final fixed position of the sealing plate 12 within the accommodating space. Specifically, as the sealing plate 12 moves, it gradually approaches the battery module 20 until it applies appropriate pressure to the battery module 20. This pressure needs to ensure that adjacent batteries 21 are tightly fitted together without damaging them. When the sealing plate 12 reaches this predetermined position, it applies appropriate pressure to the battery module 20, ensuring that two adjacent batteries 21 are tightly fitted together, and then the sealing plate 12 is fixedly connected to the surrounding plate 11.

[0042] In one embodiment, each battery module 20 includes a first battery module 22 and a second battery module 23. The top of both the first battery module 22 and the second battery module 23 is provided with a support plate 30. Multiple signal acquisition components are provided on the support plate 30. Each signal acquisition component includes an acquisition board 31 and a signal harness 32 electrically connected to the acquisition board 31. The batteries 21 in the first battery module 22 and the second battery module 23 are respectively electrically connected to the corresponding acquisition board 31.

[0043] In this embodiment, a support plate 30 is provided on the top of the battery module 20. During assembly, the signal acquisition component is first installed on the support plate 30. The main function of the signal acquisition component is to collect and monitor the operating status information of the battery 21. It includes two key parts: an acquisition board 31 and a signal harness 32 electrically connected to the acquisition board 31. The acquisition board 31 is used to collect the operating status information of the battery 21, including but not limited to parameters such as the voltage and current of the battery 21. The acquisition board 31 has reserved positive and negative electrode tabs for electrical connection with the battery 21, while the signal harness 32 is responsible for transmitting the signal data acquired by the acquisition board 31. The electrode tabs actually pass through the bottom of the support plate 30, so that the acquisition board 31 can be electrically connected to the corresponding battery 21 when the support plate 30 is placed on the battery module 20.

[0044] Specifically, both the first battery module 22 and the second battery module 23 have a support plate 30 on their tops, and each support plate 30 is equipped with multiple signal acquisition components. Each signal acquisition component includes an acquisition board 31 and a signal harness 32 electrically connected to the acquisition board 31. The batteries 21 in the first battery module 22 are electrically connected to their corresponding acquisition boards 31 on their support plates 30, and the batteries 21 in the second battery module 23 are also electrically connected to their corresponding acquisition boards 31 on their support plates 30.

[0045] In practice, since the signal acquisition components are pre-installed on the support plate 30, the operator only needs to place the support plate 30 over the top of the corresponding battery module 20, and then establish an electrical connection with the battery 21 through the reserved tab interface to complete the installation. This pre-assembly method not only simplifies the on-site installation steps and improves assembly efficiency, but also ensures the standardization of the entire installation process.

[0046] The advantages of this design are as follows: First, by pre-assembling the signal acquisition components onto the support plate 30, the tedious process of installing each acquisition board 31 individually on-site is avoided, improving assembly efficiency. Second, since the positions of the acquisition components have been pre-adjusted and fixed, when the support plate 30 is placed on the battery module 20, the acquisition board 31 can be aligned with the connection position of the battery 21, requiring only the electrical connection of the tabs to be completed, which ensures the reliability and consistency of the installation quality. Furthermore, this modular design allows for quick maintenance by replacing the entire support plate 30 assembly during later maintenance, greatly improving maintainability.

[0047] In one embodiment, the top of the support plate 30 is provided with two opposing first limiting parts 33, and the two first limiting parts 33 form receiving grooves 34 between the support plate 30 and the support plate 30, and the signal harness 32 is disposed in the receiving groove 34 adjacent to it.

[0048] In this embodiment, the top of the support plate 30 is provided with two opposing first limiting portions 33. Each first limiting portion 33 extends vertically upward from the top surface of the support plate 30. Specifically, a groove-shaped space is formed between the first limiting portion 33 and the top surface of the support plate 30, which is a receiving groove 34 for accommodating the signal harness 32. Since the first limiting portion 33 extends vertically upward, one side (bottom) of the receiving groove 34 is the top surface of the support plate 30, and the other side is the outer wall surface of the first limiting portion 33. This structure forms a semi-enclosed space, which can effectively accommodate and protect the signal harness 32.

[0049] In practical implementation, since each battery 21 needs to be equipped with a data acquisition board 31 for status monitoring, multiple signal harnesses 32 will be formed. To ensure that these signal harnesses 32 are distributed in an orderly manner, two first limiting parts 33 are located on opposite sides of the top of the support plate 30, forming two spaces for arranging the harnesses. Each signal harness 32 is set in an adjacent receiving slot 34. This regional arrangement makes the harness routing clearer. At the same time, the structure of the receiving slot 34 also provides physical protection for the harnesses, preventing them from being damaged by external forces during use.

[0050] The advantages of this design are as follows: First, the vertical extension structure of the first limiting part 33 forms a receiving groove 34 specifically for accommodating the wire harness, making the wire harness arrangement more standardized and orderly; second, the semi-enclosed structure of the receiving groove 34 not only provides a fixed arrangement space for the signal wire harness 32, but also prevents the wire harness from shifting during the overall installation of the support plate 30; third, this area-based arrangement method facilitates the maintenance and troubleshooting of the wire harness in the later stages.

[0051] In one embodiment, the top of the support plate 30 is also provided with a plurality of second limiting parts 35, which are spaced apart along the arrangement direction of the battery 21; a wire harness channel 36 is formed between two adjacent second limiting parts 35, and the wire harness channel 36 is used to accommodate the signal wire harness 32 of the adjacent acquisition board 31.

[0052] In this embodiment, in addition to the first limiting part 33, the top of the support plate 30 is also provided with a plurality of second limiting parts 35. These second limiting parts 35 are spaced apart along the arrangement direction of the batteries 21. Here, the arrangement direction refers to the arrangement direction of the batteries 21 within the accommodating space, that is, the second limiting parts 35 are arranged sequentially and spaced apart along the arrangement direction of the batteries 21 of each battery module 20. Specifically, a wiring harness channel 36 is formed between two adjacent second limiting parts 35, and the wiring harness channel 36 is used to accommodate the signal harness 32 of the adjacent acquisition board 31.

[0053] In practical implementation, since each battery 21 needs to be equipped with a data acquisition board 31 for status monitoring, multiple signal harnesses 32 will be formed. To ensure that these signal harnesses 32 are distributed in an orderly manner, the second limiting part 35 is arranged according to the following principles: First, multiple second limiting parts 35 are arranged sequentially and at intervals along the direction of battery 21 arrangement, so that an independent harness channel 36 is formed between every two adjacent second limiting parts 35; second, each harness channel 36 is specifically used to accommodate the signal harness 32 connected to its adjacent data acquisition board 31.

[0054] The advantages of this structural design are as follows: First, the spaced arrangement of the second limiting parts 35 forms multiple independent wire harness channels 36, giving each acquisition board 31's signal harness 32 its own dedicated space, avoiding the problem of wire harnesses from different acquisition boards 31 crossing or mixing. Second, this regional arrangement allows for clear identification of the wire harnesses on each acquisition board 31, enabling quick location of specific wire harnesses during later maintenance or troubleshooting, thus improving maintenance efficiency. Finally, by fixing the signal harness 32 of each acquisition board 31 within its corresponding wire harness channel 36, this design reduces the possibility of signal harness 32 moving or loosening, thereby ensuring the safety and reliability of the wire harnesses during use.

[0055] In one embodiment, an isolation member 40 is provided between the two first limiting parts 33, and an explosion-proof valve 211 is provided on the top of the battery 21 in the first battery module 22 and the second battery module 23, respectively. The explosion-proof valve 211 is located inside the corresponding isolation member 40.

[0056] In this embodiment, an isolation member 40 is provided between the two first limiting portions 33, and the isolation member 40 is used in conjunction with the explosion-proof valve 211 in the battery module 20. Specifically, each battery 21 in the first battery module 22 and the second battery module 23 is provided with an explosion-proof valve 211 on its top, and these explosion-proof valves 211 are all located inside the corresponding isolation member 40.

[0057] The isolator 40 is installed between the two first limiting parts 33 to form a protective structure for the explosion-proof valve 211. After the battery module 20 is installed, the explosion-proof valves 211 of all batteries 21 are arranged inside the isolator 40, which ensures the safety of the explosion-proof valves 211 during operation.

[0058] The advantages of this structural design are: the isolation element 40 provides a dedicated protective space for the explosion-proof valve 211, preventing the explosion-proof valve 211 from being affected by external interference or damage during installation and use; at the same time, when the battery 21 experiences an abnormal situation and needs to be depressurized, the isolation element 40 can act as a guide, allowing the depressurized gas to be discharged in a predetermined direction, thus preventing the depressurization process from affecting surrounding components.

[0059] In one embodiment, the isolation member 40 includes: a base plate 41 and vertical plates 42 disposed on opposite sides of the base plate 41. The vertical plates 42 and the base plate 41 form an isolation groove 43. The top ends of the vertical plates 42 extend toward the center of the isolation groove 43 to form support portions 421. There is a gap between the two support portions 421. The base plate 41 is provided with a plurality of through slots 411. The plurality of through slots 411 are spaced apart along the arrangement direction of the batteries 21. Explosion-proof valves 211 are respectively disposed in the through slots 411.

[0060] In this embodiment, the base plate 41 is connected to the support plate 30, and the vertical plates 42 are vertically arranged on opposite sides of the base plate 41, forming an isolation groove 43 between the vertical plates 42 and the base plate 41. The top of the vertical plate 42 extends inward to a certain extent to form a support portion 421 for supporting the component located above. There is a certain gap between the support portions 421 formed by the two vertical plates 42, which communicates with the isolation groove 43 and the through groove 411 respectively. Multiple through grooves 411 on the bottom side of the base plate 41 are arranged along the arrangement direction of the battery 21, and explosion-proof valves 211 are respectively arranged in the corresponding through grooves 411.

[0061] This structural design has the following advantages: First, the combination of the base plate 41, vertical plate 42, and through slot 411 provides all-around protection for the explosion-proof valve 211. The isolation slot 43 prevents interference between the explosion-proof valve 211 and surrounding components, while the through slot 411 ensures the normal operation of the explosion-proof valve 211. Second, the support portion 421, formed by the inward extension of the top of the vertical plate 42, provides reliable support for the components above. Third, the spaced arrangement of multiple through slots 411 corresponds to the arrangement direction of the batteries 21, ensuring that each explosion-proof valve 211 can accurately correspond to the corresponding through slot 411 position, facilitating installation and maintenance.

[0062] In practical use, the through groove 411 of the base plate 41 provides a pressure relief channel for the explosion-proof valve 211, while the vertical plate 42 and the top support 421 form a protective structure to prevent interference from other components to the explosion-proof valve 211. The gap between the two support parts 421 provides a channel for the discharge of depressurized gas, ensuring a smooth depressurization process.

[0063] In one embodiment, the top of the sealing plate 12 is provided with two grooves 121, and an insulating seat 50 is respectively inserted into the grooves 121. A connecting plate 63 is provided between one end of the first battery module 22 and the second battery module 23, and the opposite ends of the connecting plate 63 are respectively fixedly connected to the insulating seat 50.

[0064] In this embodiment, insulating bases 50 are provided at both ends of the first battery module 22 and the second battery module 23. Each insulating base 50 is connected to a data acquisition board 31 of the corresponding battery module. The data acquisition board 31 at one end is fixed to the corresponding insulating base 50 via a connecting plate 63, while the data acquisition board 31 at the other end is fixed to its corresponding insulating base 50 and connected to the main positive line 61 and the main negative line 62. This structural design not only ensures reliable signal acquisition from the battery module 20 but also guarantees the safety of the electrical connections.

[0065] In one embodiment, the groove 121 includes a communicating upper opening 122 and a lower receiving cavity 123, the width of the upper opening 122 being smaller than the width of the lower receiving cavity 123; the insulating seat 50 includes a connected head 51 and a fixing part 52, the width of the head 51 being smaller than the width of the fixing part 52, the head 51 passing through the upper opening 122, and the fixing part 52 being received in the lower receiving cavity 123, with a height difference between the fixing part 52 and the lower receiving cavity.

[0066] In this embodiment, the groove 121 adopts a stepped structure design, including a connected upper opening 122 and a lower receiving cavity 123, wherein the width of the upper opening 122 is smaller than the width of the lower receiving cavity 123. Correspondingly, the insulating base 50 also adopts a matching structure, including a connected head 51 and a fixing part 52, wherein the width of the head 51 is smaller than the width of the fixing part 52. During installation, the head 51 passes through the upper opening 122, and the fixing part 52 is received in the lower receiving cavity 123.

[0067] In practical implementation, the narrower design of the upper opening 122 guides the head 51 of the insulating base 50 to be accurately inserted, while the wider design of the lower receiving cavity 123 provides suitable installation space for the fixing part 52. During installation, the insulating base 50 is inserted into the groove 121 from front to back. After the fixing part 52 is fully inserted into the lower receiving cavity 123, a certain gap will remain between its top surface and the lower receiving cavity 123. This gap is designed to ensure that the fixing part 52 has a certain vertical movement space after insertion, thereby accommodating positional changes of the support plate 30 and its signal acquisition components due to various factors, improving the overall installation flexibility and adaptability.

[0068] The advantages of this structural design are as follows: First, the stepped design ensures accurate positioning and installation of the insulating base 50; second, the dimensional difference between the upper opening 122 and the lower accommodating cavity 123 ensures ease of installation while providing necessary space for the fixing part 52 to move; third, the gap between the fixing part 52 and the lower accommodating cavity 123 effectively accommodates positional changes in the support plate 30 and the signal acquisition component, improving the adaptability of the entire component during installation. The overall structural design ensures both installation reliability and provides necessary positional adjustment margin.

[0069] In one embodiment, the enclosure 11 includes a supporting base plate 111 and side plates 112 disposed on opposite sides of the supporting base plate 111. The supporting base plate 111 and the side plates 112 enclose a receiving space. A partition 13 is disposed between the side plates 112. A sealing plate 12 is disposed at opposite ends of the supporting base plate 111.

[0070] In this embodiment, the enclosure 11 adopts a combined structural design, including a supporting base plate 111 and side plates 112 disposed on opposite sides of the supporting base plate 111. Specifically, the supporting base plate 111 and the side plates 112 enclose a receiving space for accommodating the battery module 20. A partition 13 is disposed between the side plates 112, dividing the receiving space into two independent cavities. Sealing plates 12 are respectively disposed at opposite ends of the supporting base plate 111 for fixing the battery module 20 within the receiving space.

[0071] In practical implementation, the supporting base plate 111 serves as the foundation of the entire enclosure 11 structure, with side plates 112 vertically arranged on its opposite sides. The connection between the side plates 112 and the supporting base plate 111 forms the basic outline of the accommodating space. A partition 13 is vertically arranged between the two side plates 112, dividing the entire accommodating space into two independent cavities for accommodating the first battery module 22 and the second battery module 23, respectively. A sealing plate 12 is provided at each end of the supporting base plate 111. When the battery module 20 is placed into the accommodating space, the battery module 20 is pressed and fixed by the movement and fixation of one of the sealing plates 12.

[0072] This structural design has the following advantages: First, the combination of the supporting base plate 111 and the side plate 112 forms a stable housing space frame, providing reliable support and protection for the battery module 20; second, the partition plate 13 between the side plates 112 effectively separates the space; third, the design of setting the sealing plates 12 at both ends of the supporting base plate 111 makes the installation and fixing of the battery module 20 more flexible and reliable, and facilitates maintenance and replacement.

[0073] In this embodiment, there are actually two sealing plates 12, which are respectively set at both ends of the supporting base plate 111.
