The process of assembling lithium battery cells into groups is called PACK, which can be a single battery or battery modules connected in series and parallel. At present, the demand for lithium batteries is increasing, and many lead-acid battery companies have also launched lithium battery products. In fact, the technology of lithium battery PACK is not difficult. Mastering this technology can assemble batteries by yourself, instead of just acting as a role of “battery porter”. Profits and after-sales are no longer controlled by others. Mastering the lithium technology could help you to travel all over the world.
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.
The characteristics of PACK include that the battery pack requires a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life). The cycle life of the battery pack is lower than the cycle life of a single battery. Pack should be used in specific conditions (including charging, discharging current, charging method, temperature, etc.). After the lithium battery pack is formed, the voltage and capacity of the battery are greatly improved, and it must be protected by charging equalization, temperature, voltage and overcurrent monitoring. The battery pack PACK must meet the voltage and capacity requirements of the design.
In the process of pack production, such as nickel sheet, copper-aluminum composite busbar, copper busbar, total positive busbar, aluminum busbar, copper flexible connection, aluminum flexible connection, copper foil flexible connection, etc. will be used. The processing quality of busbars and flexible connections needs to be evaluated from these aspects.
