The pack consists of battery pack, bus bar, flexible connection, protection board, outer package, output (including connector), highland barley paper, plastic bracket and other auxiliary materials.

Lithium battery pack means packaging, packaging and assembly. Its processes are divided into three parts: processing, assembly and packaging. PACK is a single component. PACK production line generally only needs to undertake two functions: transmission and detection. At present, semi-automatic PACK assembly lines are widely used by manufacturers, mainly for online, offline, detection, in plant transmission and packaging of PACK.

The lithium battery pack production line is relatively simple. The core processes include feeding, bracket pasting, electric welding, testing and other processes. The core equipment are laser welding machines and various types of pasting testing equipment. At present, the major lithium battery equipment manufacturers have less automation integration layout in this field, while laser equipment manufacturers such as Han's Laser and Lianying Laser have a high share in the field of pack equipment due to their absolute advantages in the laser field.
