In the production process of lithium battery pack, the standard of cell surface pad: the surface pad is required to be firmly pasted, not tilted and warped, not beyond the edge of the end face of the cell, and not cover the negative rivet (for aluminum shell cell) and positive cap (for steel shell cell). The purpose of pasting insulating paper on the battery is to avoid the short circuit of the battery cell itself or the short circuit of the battery block during the assembly process, which will burn the protective circuit or components and hurt the human body. Commonly used highland barley paper, PVC, etc. Highland barley paper has good insulation, water resistance and wear resistance, which can effectively prevent the positive and negative short circuit of power battery pack during vibration.
The positions where insulation protection is usually required are:
1. Between the contact surface of the BMS board and the battery cell: the paper is required to completely cover the contact surface of the BMS board and the battery to avoid short circuit of the battery;
2.Protect the overlap position of the different polarities of nickel strips, pads, traces and plugs and leads on the BMS board: insulation is required to completely cover the contact surface that can cause a short circuit between the two to avoid short circuit of the battery;
3.When the batteries are connected in series, the joint insulation pads should be attached to the series end, and then the nickel strip should be spot-welded in series to prevent the positive pole cell in the series from short-circuiting;
4. When the battery cells are connected in parallel, the positive pole of the battery should be attached to the barley paper device. The positive pole of the battery cell should be attached to the joint insulation pad. The positive pole of the battery can be attached to the barley paper device, and then the nickel strip can be connected in series to prevent the battery itself from short-circuiting.
