Description

Technical Field

[0001] This utility model belongs to the field of lithium-ion batteries, specifically referring to a heat insulation bracket for a lithium-ion battery protection board. Background Technology

[0002] Lithium-ion batteries are widely used in electric vehicles, energy storage systems, and consumer electronics due to their high energy density and long cycle life. However, lithium-ion batteries generate a significant amount of heat during charging and discharging. If this heat cannot be effectively dissipated, it can lead to overheating and potentially cause thermal runaway and other safety incidents. The Battery Management System (BMS) protection board, as a crucial component of the lithium-ion battery pack, also generates heat during operation.

[0003] In existing technologies, thermal management between the protection board and the battery typically employs two methods: one is to place the protection board directly in contact with the battery, and the other is to insulate heat by adding a separator (such as a metal plate, epoxy board, or foam) between the protection board and the battery. However, these methods suffer from heat accumulation, leading to an increase in the internal temperature of the battery pack and increasing the risk of thermal safety accidents. Utility Model Content

[0007] The bottom of the base plate has an opening to facilitate heat dissipation;

[0008] The main body of the support is coated with a special heat-insulating coating with a thickness of 0.05 to 0.1 mm.

[0009] Several upright plates are fixed to the side of the enclosure, and bolt holes are opened on the upright plates. The plates are spliced ​​and installed with the adjacent support body through the bolt holes.

[0010] Furthermore, the main body of the support is made of sheet metal or aluminum alloy, and the base plate and the enclosure are fixed by welding or bolting.

[0011] Furthermore, the heat-insulating coating is a material with extremely low thermal conductivity, selected from ceramic coatings or nano-insulating materials, which can effectively isolate the heat between the protective plate and the battery.

[0012] Furthermore, the position of the connecting post is designed according to the installation position of the lithium-ion BMS protection board body, and the bracket body and the lithium-ion BMS protection board body are fixed together by screws.

[0013] Furthermore, the bolt holes on the upright plate are used for splicing and installation with adjacent support bodies, which facilitates the assembly and fixing of multiple supports. The upright plate is provided with multiple bolt holes to accommodate adjacent support bodies of different sizes.

[0014] Furthermore, the base plate and enclosure of the main body of the support are manufactured using an integrated molding process, and reinforcing ribs are provided between the base plate and the enclosure to increase the overall strength and stability of the support.

[0015] Furthermore, the bottom opening of the base plate of the main body of the bracket is designed as a grid or strip to increase the heat dissipation area.

[0016] Furthermore, the enclosure height of the bracket body is designed according to the thickness of the lithium-ion BMS protection board body to ensure effective isolation between the protection board and the battery.

[0017] Furthermore, the heat insulation coating of the bracket body is uniformly coated on the surface of the bracket through spraying, coating or baking process, and the heat insulation coating material has the characteristics of high temperature resistance and corrosion resistance, and is suitable for various harsh environments.

[0018] Furthermore, a shock-absorbing pad is provided between the base plate of the lithium-ion BMS protection board body and the enclosure to reduce the impact and noise of the battery pack in a vibration environment.

The base plate 3 has multiple connecting posts 302, and the positions of the connecting posts 302 are designed according to the installation position of the lithium-ion BMS protection board main body 1. One side of the bracket main body 2 is coated with a ceramic coating with a thickness of 0.05mm, which can effectively isolate the heat between the protection board and the battery. Bolt holes 402 are opened on the upright plate 401 on the side of the enclosure 4, which is connected to the adjacent bracket main bodies 2 by bolts to realize the splicing and installation of multiple brackets.
