1、 What does the lithium battery PACK mean?

In the early days, battery PACK mainly refers to the processing, assembly and packaging of lithium battery packs. The process of assembling lithium battery cells into groups is called PACK, which can be a single battery or a series parallel lithium battery pack. PACK consists of battery pack, bus bar, soft connection, protection board, outer package, output (including connector), highland barley paper, plastic support and other auxiliary materials.

The lithium battery PACK system uses the mechanical structure to connect many single cells in series and parallel, and considers the system mechanical strength, thermal management, BMS matching and other issues. Its main technologies are embodied in the overall structure design, welding and processing process control, protection level, active thermal management system, etc.

2、 Features of lithium battery PACK

① PACK lithium battery pack requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).

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

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

④ The battery voltage and capacity have been greatly improved after the formation of the lithium battery pack PACK. It must be protected and monitored for charge equalization, temperature, voltage and overcurrent.

⑤ The battery PACK must meet the voltage and capacity requirements required by the design.
