Description

Technical Field

[0001] This utility model relates to the field of externally controlled BMS technology, and in particular to an externally controlled BMS energy storage air-cooled battery pack. Background Technology

[0002] The air-cooled energy storage battery pack is an energy storage device that uses air cooling for heat dissipation and is widely used in home energy systems, centralized energy storage systems, distributed energy storage systems, and cloud platform monitoring.

[0003] BMS (Battery Management System) is a key component of the battery management system, responsible for monitoring and managing individual cells or battery modules within the battery pack.

[0004] The structure of the air-cooled energy storage battery pack can be referenced in the utility model patent application with authorization number "CN221262477U", which discloses "An externally mounted BMS slave controller for an air-cooled energy storage battery pack". By externalizing the BMS slave controller, the volume encroachment on the internal enclosure is reduced, improving the space utilization of the enclosure. Furthermore, externalizing the BMS slave controller facilitates subsequent maintenance and replacement in case of BMS failure. This solves the problem in the prior art where the battery pack and BMS slave controller are integrated into the same enclosure, causing inconvenience in replacing the BMS slave controller when it fails. Additionally, the low-voltage wiring harness inside the enclosure needs to be connected to the BMS slave controller via an adapter plug on the enclosure, and the BMS slave controller then communicates externally via an adapter plug, resulting in wasted costs.

[0005] However, the BMS slave controller and the energy storage air-cooled battery pack are fixed by bolts. When maintenance or replacement of the BMS slave controller is required, it takes a lot of time and effort to disassemble and reinstall, which is quite cumbersome. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a BMS-controlled externally mounted, air-cooled energy storage battery pack.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A U-shaped mounting base is provided on the top of the energy storage air-cooled battery pack body. A BMS slave controller body is inserted into the top of the energy storage air-cooled battery pack body through the U-shaped mounting base. A limit component is inserted into the outside of the U-shaped mounting base.

[0009] The limiting component includes a connecting plate, with fixed seats symmetrically installed on both sides of the connecting plate. Multiple T-shaped blocks are slidably arranged in the fixed seats at equal distances, and a limiting rod is inserted through the center of each T-shaped block. A limiting plate and a handle are fixedly installed on both sides of the limiting rod, and a fixing ring is fixedly sleeved on the outer wall of the limiting rod in the center of the T-shaped block. A spring body is provided in the fixed seat on one side of the T-shaped block.

[0010] In addition, a preferred structure is that a fixing plate is provided on one side of the fixing base outside the limiting rod, and an auxiliary groove is provided on one side of the fixing plate.

[0011] Furthermore, in a preferred configuration, a sliding groove is provided in the fixing seat at the T-shaped insert, and a through hole is provided in the fixing seat at the limiting insert.

[0012] In addition, a preferred structure is that the BMS has extension plates symmetrically installed on both sides of the control body, and a limit slot is opened through the extension plate at the limit plate.

[0013] Furthermore, in a preferred configuration, the U-shaped mounting base has a slot at the extension plate, an auxiliary groove at the T-shaped insert, a movable cavity at the limiting plate, and an inlet / outlet slide groove on one side of the movable cavity. The inlet / outlet slide groove and the auxiliary groove are parallel, and the cross-sectional areas of the inlet / outlet slide groove and the auxiliary groove are consistent with the cross-sectional area of ​​the limiting plate.

[0014] Furthermore, in a preferred configuration, the fixing seat is L-shaped, and a T-shaped fixing block is fixedly installed on one side of the fixing seat, and a limiting groove is provided on the outer side of the U-shaped mounting seat at the T-shaped fixing block.

A BMS slave controller body 2 is inserted into the top of the energy storage air-cooled battery pack body 1 through the U-shaped mounting base 11, and a limiting component 3 is inserted into the outside of the U-shaped mounting base 11. It is worth noting that the specific structure, connection method and working principle of the energy storage air-cooled battery pack body 1 and the BMS slave controller body 2 are all existing technologies that have been disclosed in the market and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0025] Furthermore, the limiting component 3 includes a connecting plate 32, with fixed seats 31 symmetrically installed on both sides of the connecting plate 32. Multiple T-shaped inserts 34 are slidably arranged in the fixed seats 31 at equal distances. A limiting rod 344 is inserted through the center of the T-shaped insert 34. A limiting plate 342 and a handle 343 are fixedly installed on both sides of the limiting rod 344, and a fixing ring 341 is fixedly sleeved on the outer wall of the limiting rod 344 in the middle of the T-shaped insert 34. A spring body 345 is provided in the fixed seat 31 on one side of the T-shaped insert 34.

[0026] Furthermore, a limiting cavity is provided inside the T-shaped insert 34 at the fixing ring 341.

[0028] Meanwhile, a sliding groove is provided in the fixed base 31 at the T-shaped insert 34, and a through hole is provided in the fixed base 31 at the limiting insert 344.

[0029] Furthermore, extension plates 21 are symmetrically installed on both sides of the BMS control body 2, and a limit slot is opened through the extension plate 21 at the limit plate 342.

[0030] Furthermore, a slot is provided in the U-shaped mounting base 11 at the extension plate 21, and an auxiliary groove is provided in the T-shaped insert 34 of the U-shaped mounting base 11. A movable cavity is provided in the U-shaped mounting base 11 at the limiting plate 342, and an inlet / outlet slide groove is provided on one side of the movable cavity in the U-shaped mounting base 11. The inlet / outlet slide groove and the auxiliary groove are parallel, and the cross-sectional area of ​​the inlet / outlet slide groove and the cross-sectional area of ​​the auxiliary groove are consistent with the cross-sectional area of ​​the limiting plate 342.
