[0036] The core of the present invention is to provide a high-voltage household energy storage battery system, and the capacity adjustment of the high-voltage household energy storage battery system is simple and easy, enabling users to flexibly and efficiently adjust the capacity of the high-voltage household energy storage battery system according to actual working conditions.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the following will further describe the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0038] In a specific embodiment, the high-voltage household energy storage battery system provided by the present utility model includes at least two stacking boxes 11 arranged in sequence from bottom to top in the vertical direction and stacked in a detachable manner. One of the stacking boxes 11 is a high-voltage control box with a circuit management module 14 arranged inside, and the remaining stacking boxes 11 except the high-voltage control box are battery boxes with a battery core energy storage module arranged inside; a bridging component capable of being electrically connected to the battery core energy storage module and / or the circuit management module 14 is arranged between two adjacent stacking boxes 11.

[0039] During the operation and working process of the equipment, according to the current actual working condition power consumption requirements of the user, the corresponding number of battery boxes is selected, and these battery boxes and a high-voltage control box are stacked in sequence in the vertical direction to form a regular component structure in which multiple stacking boxes 11 are stacked in sequence. The high-voltage control box is electrically connected to the adjacent battery box and any two adjacent battery boxes through the bridging component to ensure the reliable electrical connection and communication connection of the circuit management module 14 and each battery core energy storage module. After the stacking assembly and electrical connection are completed, the working state of the entire high-voltage household energy storage battery system can be regulated and managed by relying on the circuit management module 14 in the high-voltage control box to ensure the power consumption requirements under the actual working conditions.

[0040] If it is necessary to adjust the overall battery capacity of the high-voltage household energy storage battery system, a newly added battery box can be stacked in place on the original stacking component of multiple stacking boxes 11 to form a new stacking component structure of the stacking boxes 11, so as to realize the capacity expansion operation of the high-voltage household energy storage battery system; any number of original battery boxes in the high-voltage household energy storage battery system can also be removed, and the remaining stacking boxes 11 are stacked in place to form a new stacking component structure of the stacking boxes 11, so as to realize the capacity reduction process of the high-voltage household energy storage battery system.

[0041] In this way, through the flexible increase and decrease and stacking arrangement of the battery boxes, the flexible adjustment of the overall battery capacity of the high-voltage household energy storage battery system can be realized, greatly improving the corresponding capacity expansion and reduction processing efficiency. And the entire battery capacity adjustment process only needs to simply carry and stack the stacking boxes 11 to complete, greatly reducing the difficulty of component disassembly and assembly operations, enabling the user to flexibly and efficiently adjust the capacity of the high-voltage household energy storage battery system according to the actual working condition requirements, and the adjustment operation process is simple and easy to implement.

[0042] Generally, the specific shape of the stacking box 11 is preferably a flat cuboid as shown in the figure, so as to optimize the structural stability after multiple stacking boxes 11 are stacked, improve the reliability of the overall assembly structure of the high-voltage household energy storage battery system, and enable the overall structure of the components after multiple stacking boxes 11 are stacked and assembled to be more regular and beautiful, so as to optimize the appearance of the high-voltage household energy storage battery system.

[0043] Specifically, the bottom of the stacking box 11 is provided with protruding positioning columns 111, and the top of the stacking box 11 is provided with positioning holes 112 that are in one-to-one correspondence with the positioning columns 111 and are adapted for alignment and insertion. When two adjacent stacking boxes 11 are stacked and assembled in alignment, the positioning columns 111 of the stacking box 11 located above can be inserted into the positioning holes 112 of the stacking box 11 located below in one-to-one correspondence, so as to achieve precise alignment and reliable limit of two adjacent stacking boxes 11. This can not only improve the assembly accuracy between adjacent stacking boxes 11, but also form a reliable limit in the horizontal direction for two adjacent stacking boxes 11, avoiding shaking, loosening or dislocation of the component structure arranged by stacking multiple stacking boxes 11, and further avoiding the collapse or overturning of the high-voltage household energy storage battery system, thereby further optimizing the assembly structure stability of the high-voltage household energy storage battery system and making its component structure more regular and reliable.

[0044] Considering the conventional working condition requirements in most cases, the stacking box 11 is a metal box processed from steel or other rigid metal materials, so as to ensure the structural strength and load-bearing capacity of the stacking box 11, thereby meeting the assembly strength requirements for multiple stacking boxes 11 arranged in a stacked manner in the high-voltage household energy storage battery system.

[0045] On this basis, a sprayed plastic protective layer can be coated on the outer surface of the stacking box 11, so as to optimize the insulation effect of the stacking box 11, avoid electric leakage, and form sufficient protection for the main structure of the metal material of the stacking box 11, avoiding damage to the main structure of the stacking box 11 due to rigid contact with other equipment, so that the stacking box 11 is more durable, and accordingly improve the overall service life and working condition tolerance of the high-voltage household energy storage battery system.

[0046] Correspondingly, the positioning column 111 is also preferably a metal material part with its outer surface subjected to plastic dipping treatment, so as to form the main structure of the positioning column 111 by using metal materials, improve the main structure strength and load-bearing capacity of the positioning column 111, and can form sufficient structural protection and insulation treatment for the positioning column 111 by using the plastic material layer formed on the outer surface of the positioning column 111 after plastic dipping treatment, so as to cooperate with the main structure of the stacking box 11 and optimize the overall structural strength and working condition tolerance of the high-voltage household energy storage battery system.

[0047] Furthermore, the positioning columns 111 are arranged in an array at the respective top corners of the bottom surface of the stacking box 11, and the positioning holes 112 are arranged in an array at the respective top corners of the top surface of the stacking box 11. Arranging the positioning columns 111 and the positioning holes 112 at the respective top corners of the stacking box 11 is beneficial to further optimizing the stress distribution after the stacking boxes 11 are arranged in a stacked manner, avoiding structural damage or deformation of the stacking box 11 caused by local stress concentration, and thereby further improving the structural reliability and service life of the stacking box 11.

[0048] Specifically in practical applications, a support foot 13 is detachably installed at the bottom end of the positioning column 111 of the stacking box 11 located at the bottom in the vertical direction. The support foot 13 provides reliable structural support for the overall structure of the high-voltage household energy storage battery system, improves the overall structural stability of the high-voltage household energy storage battery system, and prevents the main structures of the stacking box 11 and the positioning column 111 from directly contacting the bearing surface such as the ground, so as to avoid non-operational damage to the main structures of the stacking box 11 and the positioning column 111, and improve the working condition adaptability and service life of the high-voltage household energy storage battery system.

[0049] Generally, the support foot 13 can be a soft pad made of plastic or rubber material, or a rigid support member made of engineering plastic with a certain strength, and the support frame can be assembled in place on the positioning column 111 by using a threaded adaptation structure, so as to adjust the effective extension length of the support foot 13 by using the threaded adaptation structure, thereby realizing the fine adjustment and leveling of the overall height of the high-voltage household energy storage battery system.

[0050] On the other hand, the bridging assembly includes a bridging plug 121 and a bridging socket 122 that are inserted and adapted in a one-to-one correspondence. The bridging plug 121 is located at the top of the stacking box 11, and the bridging socket 122 is located at the bottom of the stacking box 11. Through the insertion of the bridging plug 121 and the bridging socket 122 in place, the electrical connection of the functional modules inside the adjacent two stacking boxes 11 is realized.

[0051] Specifically, when the high-voltage control box and the stacking box 11 are stacked and assembled, the electrical connection and communication connection between the circuit management module 14 in the high-voltage control box and the battery cell energy storage module in the stacking box 11 can be realized by inserting the bridging plug 121 on the high-voltage control box and the bridging socket 122 on the stacking box 11 in place, or by inserting the bridging socket 122 on the high-voltage control box and the bridging plug 121 on the stacking box 11 in place; when two stacking boxes 11 are stacked and assembled, the electrical connection between the battery cell energy storage modules in the adjacent two stacking boxes 11 can be realized by inserting the bridging plug 121 on one of the stacking boxes 11 and the bridging socket 122 on the other stacking box 11 in place. By assembling the bridging plugs 121 on the stacking box 11 and their corresponding bridging sockets 122 in the adjacent positions in place, the connection of the overall power supply system and control system of the high-voltage household energy storage battery system is realized, ensuring the corresponding power supply energy storage operation requirements and equipment operation control.

[0052] In fact, the bridging plug 121 can be arranged at the bottom of the stacking box 11, and the bridging socket 122 can also be correspondingly arranged at the top of the stacking box 11. However, considering the convenience during actual operation, it is still advisable to arrange the bridging plug 121 at the top of the stacking box 11 and the bridging socket 122 at the bottom of the stacking box 11 as shown in the figure.

[0053] In addition, two anti-fool positioning grooves are symmetrically arranged along the horizontal direction at the bottom of the stacking box 11, and anti-fool positioning blocks 113 which are inserted and adapted to the anti-fool positioning grooves one by one are convexly arranged at the top of the stacking box 11. The two anti-fool positioning blocks 113 on the same stacking box 11 are symmetrically arranged along the horizontal direction. When the stacking boxes 11 are stacked and assembled, the accurate alignment and assembly of two adjacent stacking boxes 11 can be realized by correspondingly inserting the anti-fool positioning blocks 113 at the top of the stacking box 11 below into the anti-fool positioning grooves at the bottom of the stacking box 11 above. Moreover, since the two anti-fool positioning grooves on the same stacking box 11 are symmetrically arranged along the horizontal direction, the front and rear end faces of the stacking box 11 in the horizontal direction can be smoothly and accurately aligned and stacked without distinction, realizing the anti-fool connection of the stacking box 11, thereby further improving the stacking and assembly efficiency of the stacking box 11 and reducing the assembly difficulty of the high-voltage household energy storage battery system.

[0054] More specifically, a handle 114 is arranged on the side of the stacking box 11. Generally, there are two handles 114, which are symmetrically arranged on both sides of the stacking box 11, so that the operator can conveniently and stably lift the stacking box 11, improving the convenience of taking and placing the stacking box 11 and the storage and transportation efficiency.

[0055] Considering the layout requirements of the general working condition environment, the stacking box 11 located at the top along the vertical direction is a high-voltage control box, and a protective cover 141 is detachably arranged on the top of the high-voltage control box. The protective cover 141 can provide reliable structural protection for the top of the high-voltage control box, preventing water and dust from invading the high-voltage control box. On this basis, the protective cover 141 can be used as the top protective part of the overall structure of the high-voltage household energy storage battery system, thereby providing reliable waterproof and dustproof protection for the top structure of the high-voltage household energy storage battery system.

[0056] Generally, an operation hole 142 communicating with its inner cavity can be arranged on the side of the high-voltage control box, so that the staff can perform operations such as maintenance and repair on the circuit management module 14 located inside the high-voltage control box through the operation hole 142. Thus, the relevant maintenance and repair processing of the high-voltage control box and the circuit management module 14 inside it can be completed without disassembling, assembling and transporting the high-voltage control box, further improving the operation and use convenience of the high-voltage household energy storage battery system.

[0057] In actual operation and application, the power consumption of different users varies. It only requires any combination of different numbers of batteries in the present utility model. Taking the power of a single battery box as 5 kW as an example: If the user's power consumption demand is 10 kW, only 2 battery boxes need to be combined and stacked with a high-voltage control box for assembly; if the user's power consumption demand is 15 kW, then 3 battery boxes are combined and stacked with a high-voltage control box for assembly; if the user's power consumption demand is 20 kW, 4 battery boxes are required to be combined and stacked with a high-voltage control box for assembly.

[0058] Considering the component processing and assembly application requirements in most cases, generally, the maximum assembly quantity of battery boxes in a single set of high-voltage household energy storage battery system is 6 battery box combinations, which can correspondingly meet the power consumption needs of 30 kW; if two sets of high-voltage household energy storage battery systems are combined and operated in parallel, the maximum power consumption demand that can be matched is 60 kW, which can fully meet the backup power energy storage needs of a family.

[0059] Of course, the maximum assembly quantity of battery boxes in the above single set of high-voltage household energy storage battery system and the power parameter of a single battery box are only for illustrative purposes. In actual application, they can be flexibly selected and adjusted according to specific working conditions. In principle, as long as it can meet the specific working condition application requirements of the high-voltage household energy storage battery system, it is acceptable.

[0060] In summary, for the high-voltage household energy storage battery system provided in the present utility model, during its operation and working process, according to the current actual working condition power consumption demand of the user, the corresponding number of battery boxes is selected, and these battery boxes and a high-voltage control box are stacked vertically in sequence to form a regular component structure with multiple stacked connection boxes stacked in sequence. The high-voltage control box is electrically connected to its adjacent battery box, and any two adjacent battery boxes are electrically connected through a bridging component to ensure reliable electrical connection and communication connection of the circuit management module and each battery core energy storage module. After the stacking assembly and electrical connection are completed, the working state of the entire high-voltage household energy storage battery system can be regulated and managed by relying on the circuit management module in the high-voltage control box to ensure the power consumption demand under the actual working condition. If it is necessary to adjust the overall battery capacity of the high-voltage household energy storage battery system, the newly added battery box can be stacked on the original stacked component of multiple stacked connection boxes in place to form a new stacked component structure of stacked connection boxes, thereby realizing the capacity expansion operation of the high-voltage household energy storage battery system; or any number of original battery boxes in the high-voltage household energy storage battery system can be removed, and the remaining stacked connection boxes are stacked in place to form a new stacked component structure of stacked connection boxes, thereby realizing the capacity reduction process of the high-voltage household energy storage battery system. In this way, through the flexible addition and subtraction and stacking arrangement of the battery boxes, the flexible adjustment of the overall battery capacity of the high-voltage household energy storage battery system can be realized, greatly improving the corresponding capacity expansion and reduction processing efficiency. Moreover, the entire battery capacity adjustment process only needs to simply carry and stack the stacked connection boxes to complete, greatly reducing the operation difficulty of component disassembly and assembly, enabling the user to flexibly and efficiently adjust the capacity of the high-voltage household energy storage battery system according to the actual working condition demand, and the adjustment operation process is simple and easy to implement.
