Technical Process of the Power Lithium Battery Pack (PACK) Production Line — dynamic screening of 100–1000 channels — series/parallel connection according to quantity requirements — outsourced processing and production of the BMS system — parameter calibration, performance testing, and cable fabrication — enclosure fabrication, heat dissipation, shielding and interfaces, integration of the battery pack and BMS system — rapid quality inspection and issuance of performance parameter data, packaging, certificate of conformity, and computer-automated matching. The automated integration business of power batteries generally includes fully automatic/semi-automatic assembly lines for modules and PACKs. Manufacturers generally use semi-automatic PACK assembly lines, mainly for the three major parts of PACK loading, unloading, and packaging.
PACK is a single component. A PACK production line generally only needs to undertake two functions: conveying and testing. At present, however, PACK is a single component. A lithium battery module is multiple PACKs composed of a few to hundreds of battery cells connected in parallel and series.
I. The main processes of a power battery PACK production line include:
-
Sorting and matching process.
-
Automatic welding process.
-
Semi-finished product assembly process.
-
Aging test process.
-
PACK testing process.
-
PACK packaging process.
II. What does lithium battery PACK grouping mean?
It means combining individual lithium batteries into a lithium battery pack through series and parallel connections. The voltage and capacity of the lithium battery pack can be configured according to one's own needs. PACK is short for battery pack.
III. Differences between power lithium battery modules and PACKs:
A lithium battery module is a relatively complete system, while a PACK is a single component.
A lithium battery module is multiple PACKs composed of a few to hundreds of battery cells connected in parallel and series. In addition to the mechanical design, adding a battery management system and a thermal management system can form a relatively complete lithium battery pack system.
PACK means packaging, encapsulation, and assembly. Its processes are divided into three major parts: processing, assembly, and packaging. A PACK is a single component. A PACK production line generally only needs to undertake two functions: conveying and testing. At present, manufacturers generally use semi-automatic PACK assembly lines, mainly for PACK loading, unloading, testing, in-plant transportation, and packaging.
The automated integration business of power batteries generally includes fully automatic/semi-automatic assembly lines for modules and PACKs, automated equipment integration, information collection and transmission (MES), and software and hardware management systems for unmanned workshops.
