PACK, generally refers to the combination battery. PACK includes battery pack, protection plate, outer package or shell, output (including connector), key switch, power indicator, and auxiliary materials such as EVA, highland barley paper, plastic bracket, etc. The external characteristics of the PACK are determined by the application. The battery is formed by single batteries passing through and connected in series. Parallel connection increases the capacity, the voltage remains unchanged, the voltage doubles after series connection, and the capacity remains unchanged. For example, 3.6V/10Ah battery consists of a single N18650/2Ah passing through 5 parallel, 36V/2Ah battery can consist of a single N18650/2Ah passing through 10 strings, and 36V/10Ah battery consists of a single N18650/2Ah passing through 5 parallel 10 strings.

The main processes of the power battery pack production line include:
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 process.
7, the power battery automation integration business generally includes module and PACK automatic/Semi-automatic assembly line, various manufacturers generally use semi-automatic PACK assembly line, which is mainly used for PACK's on-line, off-line and packaging.
8. PACK is a single component. The PACK production line generally only needs to undertake two functions: transmission and detection.
Currently, the PACK is a single component. The lithium battery module is a plurality of PACK composed of several to hundreds of battery cells connected in parallel and series.
