LR03 battery.What processes are included in the lithium battery pack production line?

　　What processes does the lithium battery pack production line contain? The production process of lithium battery pack is relatively complex. The pack is the key to the production, design and application of the power battery system. It is the core link connecting the upstream battery production and the downstream vehicle application. Usually the design requirements are proposed by the battery factory or the automobile factory, usually by Completed by battery factory, automobile factory or third-party Pack factory.

　　What processes does the lithium battery pack production line contain?

　　1. Sorting and grouping process

　　2. Automatic welding process

　　3. Semi-finished product assembly process

　　4. Aging test process

　　5. PACK detection process

　　6. PACK packaging technology

　　Lithium battery PACK composition

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

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

　　Features of lithium battery PACK

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

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

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

　　④ After the lithium battery pack PACK is formed, the battery voltage and capacity are greatly improved, and must be protected and monitored for charge equalization, temperature, voltage and overcurrent.

　　⑤The 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 or ultrasonic welding or pulse welding. This is a commonly used welding method. The advantage is that it has better reliability but 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 lead to poor contact.

　　In the entire process from lithium battery cells to automated modules to battery PACK production lines, the degree of automation of the assembly line is a key factor in determining product quality and production efficiency. Due to the inconsistent battery PACK standards, automated manufacturing in the PACK link is almost blank. In order to further improve production efficiency and reduce costs, the application of automated lithium battery production equipment must be vigorously promoted.
