Lithium battery PACK composition

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

Lithium battery PACK means packaging, encapsulation, and assembly. The process is divided into three parts: processing, assembly, and packaging. PACK is a single component. The PACK production line generally only needs to undertake two functions: transmission and detection.

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 is a laser welding machine and various pasting testing equipment.

Features of lithium battery PACK

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

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

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

④ The battery voltage and capacity of the lithium battery pack are greatly improved after the PACK is formed, and it must be protected by charging equalization, temperature, voltage and overcurrent monitoring.

⑤Lithium battery pack PACK must meet the voltage and capacity requirements of the design.
