Description

A UPS cabinet structure Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a UPS cabinet structure. Background Technology

[0002] With the in-depth development of new energy industries such as energy storage, photovoltaics, and wind power, multiple new energy sources are integrating with each other to form complementary energy stations.

[0003] Currently, conventional UPS battery modules typically use wiring harnesses for output and single-wire communication connections. If a wiring harness malfunctions during use after system assembly, the entire cabinet's module system will malfunction and become unusable. Furthermore, wiring harness terminals are prone to overheating during high-current output. Since they are usually secured with only a single screw, this can negatively impact assembly quality, reduce connection reliability, and ultimately shorten the cabinet's lifespan.

[0004] Utility Model Content

[0005] Based on this, the present invention provides a UPS cabinet structure, which aims to solve the problems of existing UPS battery modules using wire harness connection to achieve output, abnormal wire harness causing the entire cabinet to malfunction, wire harness terminals having the risk of overheating, and low connection reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a UPS cabinet structure, including a cabinet body, wherein a battery management system and at least two adjacent rows of first and second battery cell modules are disposed within the cabinet body; the battery management system is disposed near the top of the cabinet body, and the first and second battery cell modules are disposed below the battery management system;

[0007] The first battery cell module includes several layers of first battery boxes, and the second battery cell module includes several layers of second battery boxes. The battery management system is connected to the first battery boxes near the battery management system via a first copper busbar. Adjacent first battery boxes are connected via a second copper busbar. The first battery boxes located at the bottom of the cabinet and the second battery boxes located at the bottom of the cabinet are connected via a third copper busbar. Adjacent second battery boxes are connected via a fourth copper busbar. The battery management system is connected to the second battery boxes near the battery management system via a fifth copper busbar.

[0008] The first copper busbar, several second copper busbars, the third copper busbar, several fourth copper busbars, and the fifth copper busbar are connected in sequence to form a U-shaped structure.

[0009] In a preferred embodiment, several second copper busbars are arranged in a linear configuration from top to bottom; several fourth copper busbars are arranged in a linear configuration from top to bottom.

[0010] In a preferred embodiment, the second copper busbar and the fourth copper busbar are arranged in a one-to-one correspondence; the second copper busbar and the fourth copper busbar arranged in a one-to-one correspondence are on the same horizontal plane.

[0011] In a preferred embodiment, the second copper busbar and the fourth copper busbar are arranged symmetrically on the same horizontal plane.

[0012] In a preferred embodiment, one end of the first copper busbar is symmetrically arranged with the fifth copper busbar; the first copper busbar is an L-shaped copper busbar; the second copper busbar, the third copper busbar, the fourth copper busbar, and the fifth copper busbar are all linear copper busbars.

[0013] In a preferred embodiment, the UPS cabinet structure further includes a center copper busbar arranged from top to bottom, one end of which is connected to the battery management system and the other end of which is connected to the bottom of the cabinet; one side of the center copper busbar is connected to at least one second copper busbar and the other side is connected to at least one fourth copper busbar.

[0014] In a preferred embodiment, several layers of the first battery box are arranged from top to bottom; several layers of the second battery box are arranged from top to bottom; and the first battery box and the second battery box are arranged in a one-to-one correspondence.

Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] Specifically, as shown in Figures 1 and 2, this utility model embodiment proposes the following technical solution: a UPS cabinet structure, including a cabinet 10, wherein a battery management system 20 and at least two adjacent rows of first battery cell modules 30 and second battery cell modules 40 are arranged inside the cabinet 10; the battery management system 20 is arranged near the top of the cabinet 10, and the first battery cell modules 30 and the second battery cell modules 40 are both arranged below the battery management system 20;

[0031] The first battery cell module 30 includes several layers of first battery boxes 31, and the second battery cell module 40 includes several layers of second battery boxes 41. The battery management system 20 is connected to the first battery boxes 31 near the battery management system 20 via a first copper busbar 50. Adjacent first battery boxes 31 are connected via a second copper busbar 60. The first battery boxes 31 located at the bottom of the cabinet 10 and the second battery boxes 41 located at the bottom of the cabinet 10 are connected via a third copper busbar 70. Adjacent second battery boxes 41 are connected via a fourth copper busbar 80. The battery management system 10 is connected to the second battery boxes 41 near the battery management system 10 via a fifth copper busbar 90.

[0032] The first copper busbar 50, several second copper busbars 60, the third copper busbar 70, several fourth copper busbars 80, and the fifth copper busbar 90 are connected in sequence to form a U-shaped structure.

[0033] In a preferred embodiment, several second copper busbars 60 are arranged in a linear configuration from top to bottom; several fourth copper busbars 80 are arranged in a linear configuration from top to bottom.

The larger contact area between the copper busbars effectively reduces the risk of overheating and shortens the connection distance, achieving the shortest connection path. Furthermore, the elimination of terminal connections reduces the number of connections between copper busbars and terminals, significantly lowering the risk of connection failures and directly eliminating terminal costs, thus reducing the overall material cost of the battery module.
