Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a battery core fixture. Background Art

[0002] During the charging and discharging process, lithium batteries will expand or shrink in volume due to electrochemical reactions, which may cause slight changes in the internal structure of the battery. Using a suitable fixture can fix the battery to prevent it from displacement or deformation during the cycle. In addition, lithium batteries may generate heat during the charging process. If the battery overheats, it may cause safety problems such as thermal runaway or even fire. Currently, the battery cell fixtures used in the lithium battery testing process are relatively bulky and have weak insulation, resulting in poor heat dissipation during use.

[0003] Therefore, in order to solve the technical problems of low heat dissipation efficiency and poor insulation of battery modules and battery cell clips, a battery cell fixture is needed. Utility Model Content

[0004] In order to solve the technical problems mentioned in the background technology, the utility model provides a battery core fixture, including:

[0005] Two L-shaped side panels;

[0006] The partition is arranged between two side panels;

[0007] The short sides of the two side plates are directed toward the partition, and the long sides of the two side plates are connected in parallel with the partition through corresponding fasteners to form symmetrical cell placement areas on both sides of the partition.

[0008] Furthermore, the distance between the long side surface of the L-shaped side panel and the corresponding surface of the partition is in the range of 70-73 mm.

[0009] Furthermore, the length ratio of the short side to the long side of the L-shaped side panel is in the range of (60-85): (200-230).

[0010] Furthermore, a plurality of through holes are provided on the long side surface and the short side surface of the L-shaped side plate.

[0011] Furthermore, the through holes on the long side of the L-shaped side plate are distributed in a 7x7 matrix.

[0012] Furthermore, the diameter of the through holes on the long side faces is in the range of 12-15 mm.

[0013] Furthermore, the aperture unit of the through hole located on the short side surface is 7-10 mm.

[0014] Furthermore, the number of through holes located on the short side surface is at least 9.

[0015] Furthermore, the fasteners include bolts and nuts;

[0016] The L-shaped side plate and the partition plate are provided with at least 4 bolt holes, so that the bolts can be inserted from the bolt holes of the L-shaped side plate on one side and pass through the partition plate, then pass out from the bolt holes of the L-shaped side plate on the other side and be fastened with nuts.

[0017] Furthermore, the surface of the bolt is coated with Teflon coating.

[0018] The beneficial effect of the utility model is that the utility model forms a battery cell placement area on both sides of the partition by adopting a bakelite board made of insulating material. This structural design is helpful for thermal management between battery cells because the partition can serve as thermal isolation, reduce heat conduction between battery cells, and help maintain the temperature stability of the battery.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1~Figure 2 As shown, at least one embodiment provides a battery cell fixture, comprising: two L-shaped side panels 200; a partition 100, arranged between the two L-shaped side panels 200; wherein the short sides of the two L-shaped side panels 200 both point to the partition 100, and the long sides of the two L-shaped side panels 200 are respectively connected in parallel to the partition 100 through corresponding fasteners 300 to form symmetrical battery cell placement areas 400 on both sides of the partition 100.

[0029] In some embodiments, the distance between the long side of the L-shaped side plate 200 and the corresponding side of the partition 100 is in the range of 70-73 mm. Appropriate spacing helps to dissipate heat between the cells and prevent overheating, especially under high-load working conditions, which helps to maintain battery performance and safety. Precise control of the spacing helps to maintain the stability of the entire structure and prevent structural deformation or damage caused by improper placement of the cells.

[0030] In some embodiments, the length ratio of the short side to the long side of the L-shaped side panel is in the range of (60-85): (200-230). This length ratio range helps to optimize the spatial layout enclosed by the side panels, and the longer long side helps to dissipate heat, especially when the battery cells are stacked or densely placed, it can provide a better heat conduction path, which helps to keep the battery cells working within a suitable temperature range.

[0031] In some embodiments, the long side and the short side of the L-shaped side plate are both provided with a plurality of through holes 201. The through holes can be used as channels for heat exchange to help dissipate heat, especially when heat is generated when the battery or other electronic devices are working, these through holes can effectively conduct heat, thereby reducing the operating temperature of the device and improving performance and safety.

[0032] In some embodiments, the through holes 201 on the long side of the L-shaped side plate 200 are distributed in a 7x7 matrix. The through holes distributed in the matrix can provide a uniform heat exchange area on the long side of the side plate, which helps to achieve a more uniform heat dissipation effect, avoid local overheating, and improve the thermal stability and performance of the device. At the same time, the through holes not only reduce the weight of the fixture, but also maintain a certain structural strength. Compared with a single large hole or randomly distributed small holes, the holes distributed in the matrix can provide better force distribution.

[0033] In some embodiments, the aperture range of the through holes 201 located on the long side is 12-15 mm, and the aperture unit of the through holes 201 located on the short side is 7-10 mm; the number of through holes 201 located on the short side is at least 9. In order to meet the heat dissipation requirements of different parts, the through hole sizes of the long side and the short side are different. The long side ensures a larger heat dissipation area, so the aperture is larger; and the short side has a smaller aperture selected for structural strength considerations.

[0034] In some embodiments, the fastener 300 includes a bolt and a nut; wherein the L-shaped side plate 200 and the partition 100 are provided with at least four bolt holes 202, so that the bolt is inserted from the bolt hole of the L-shaped side plate on one side and penetrates through the partition 100, and then passes out from the bolt hole of the L-shaped side plate on the other side and is fastened with the nut. The surface of the bolt is coated with a Teflon coating. By using a fastener of a bolt and a nut, a stable and reliable connection between the L-shaped side plate 200 and the partition 100 can be ensured, especially when subjected to repeated loads or dynamic loads, and the Teflon coating not only has excellent corrosion resistance and a low friction coefficient, which can reduce the wear and corrosion of the bolts during use, but also has good electrical insulation, which helps to prevent electrical short circuits, especially when used in electrical equipment, which can improve safety.

[0035] In summary, the utility model adopts a bakelite board made of insulating material to form battery cell placement areas on both sides of the partition. This structural design is helpful for thermal management between battery cells, because the partition can serve as thermal isolation, reduce heat conduction between battery cells, and help maintain the temperature stability of the battery.
