Cylindrical lithium batteries, such as 18650, 20700, 21700, 26650, 32650, etc., are often used in lithium battery packs in the field of small power and energy storage. Whether it is a lithium iron phosphate or a ternary lithium battery, we will find that the battery holder will be added when the battery pack is assembled. Do you know what’s the importance of a lithium battery pack plus a battery holder? We will share following:

No.1 Improve the Isolation and insulation

Insulation is required between the cell and the cell, otherwise, it is easy to cause a short circuit.

The battery holder acts as isolation and insulation in the lithium battery pack assembly.

If there is no battery holder bracket, there are hidden dangers between the cells, and the cells only rely on the insulation of the PVC film of the cells. If the lithium battery pack is dropped or vibrated, the PVC will be broken, resulting in a short circuit between the cells, causing the hidden danger of explosion and fire.

No.2 Create gaps to ensure good heat dissipation

With the battery holder support, the gap between cells is large and the heat dissipation performance is good. ตอนนี้, the battery holder bracket between the cell and the cell has a bracket thickness of about 1mm. The cells will not be close, the gap will be significant, and the heat dissipation will be better.

No.3 Support good structural stability

When the total number of cells in the lithium battery pack is relatively large, adding the battery holder brackets for the cells is more for the stability of the lithium battery pack structure.

For example, 72V26Ah needs to use ternary lithium 18650 cells, 20 series, 10 parallels, and 200 18650 cells to combine. The volume and weight will be relatively large. If there is no battery holder bracket, the structure of the lithium battery pack is not strong enough, and the electric vehicle product vibrates more frequently.

After a long time, the lithium battery pack is easy to disperse, and the internal process will be damaged. Coupled with the battery holder support of the cell, the internal structural stability is strengthened, and many hidden dangers will be avoided.

Especially technology-based lithium battery packs, instrumentation, robots, AGVs, ยานพาหนะไฟฟ้า, ฯลฯ. These high-end technology products will use lithium battery packs with battery holder brackets.
