The production process of the lithium battery pack is relatively complicated. The pack is the key to the production, design and application of the power battery system, and is the core link connecting the upstream cell production and downstream application.

What are the technological processes of the lithium battery pack production line?

1. Sorting and matching process

2. Automatic welding process

3. Semi-finished product assembly process

4. Aging test process

5. PACK detection process

6. PACK packaging process

Lithium battery pack composition

Pack includes battery pack, bus bar, flexible connection, protective board, outer packaging, output (including connector), highland barley paper, plastic bracket and other auxiliary materials to form the Pack.

Lithium battery Pack means packaging, encapsulation, and assembly, and its process is divided into three parts: processing, assembly, and packaging. PACK is a single component. Generally, the PACK production line only needs to undertake two functions: transmission and detection. At present, various manufacturers generally use semi-automatic PACK assembly production lines, which are mainly used for the on-line, off-line, testing, in-factory transmission and packaging of PACK.

The lithium battery Pack production line is relatively simple. The core processes include feeding, bracket sticking, electric welding, testing and other processes. The core equipment is battery OCV&ACIR sorting machine, insulation paper pasting machine, spot welding machine/laser welding machine and various testing equipments.

Features of lithium battery pack

①. The battery pack PACK requires lithium batteries to have a high degree of consistency.

②. The cycle life of the battery pack PACK is lower than that of a single battery.

③. Use under limited conditions (including charging and discharging current, charging method, temperature, etc.)

④. The battery voltage and capacity of the lithium battery pack have been greatly increased after the formation of the PACK, so it must be protected and monitored for charge equalization, temperature, voltage and overcurrent.

⑤. The lithium battery pack PACK must meet the voltage and capacity requirements required by the design.

Lithium battery PACK is realized in two ways. One is through laser welding, ultrasonic welding or pulse welding. This is a commonly used welding method. It has the advantage of good reliability, but it is not easy to replace. The second is contact through elastic metal sheets. The advantage is that no welding is required, and the battery is easy to replace. The disadvantage is that it may cause poor contact.

Throughout the entire process from lithium battery cells to automated modules and then to the battery PACK production line, the degree of automation of the assembly line is a key factor in determining product quality and production efficiency.
