Analysis of battery pack assembly process and characteristics

The battery pack assembly process has seven major links: sorting and matching group process, automatic welding process, semi-finished product assembly process, aging detection process, pack testing process, and pack packaging process. The battery pack is realized in two ways. One is laser welding, ultrasonic welding or pulse welding. This is a commonly used welding method. The advantage is that it has better reliability, but it is not easy to replace. The second is contact through the elastic metal sheet. The advantage is that no welding is required and the battery is easy to replace, but the disadvantage is that it may cause poor contact. In the entire process from lithium-ion battery cells to automated modules to the battery pack processing line, the degree of automation of the assembly line is a key factor in determining product quality and processing efficiency. Because the battery pack standard is not uniform, the automated manufacturing in the pack link is almost blank. In order to further improve the processing efficiency and reduce the cost, it is necessary to vigorously promote the application of lithium-ion battery automated processing equipment. Features of the battery pack 1. The battery pack requires lithium-ion batteries to have a high degree of consistency; 2. The cycle life of the battery pack is lower than that of a single battery; 3. Use under limited conditions (including charging and discharging current , Charging method, temperature, etc.; 4. After the lithium-ion battery pack pack is formed, the battery voltage and capacity are greatly improved, and must be protected by charging equalization, temperature, voltage and overcurrent monitoring; 5. lithium-ion battery pack pack Must meet the design requirements for voltage and capacity.
