The rapid growth of the electric vehicle market has made power battery production and assembly integral to automotive manufacturing. Battery MODULE and PACK laser welding lines are crucial, performing tasks such as cell assembly, interconnection, testing, and packaging. Their efficiency directly affects battery quality, production speed, and cost control.
What Are Battery Module and PACK Welding and Assembly Line ?
The Battery Module is an intermediate step in the production of power batteries. Its primary task is to combine multiple cells (such as cylindrical, prismatic, or pouch cells) into modular units through a series of precise assembly processes. The stability and consistency of the module are critical for the subsequent PACK assembly process. Typical processes in module production include: cell loading, OCV testing, plasma cleaning, glue application, laser welding, module stacking and strapping.
PACK (Battery Pack) is the process of integrating and completing the modules by assembling them with the cooling system, electrical connection components, casing, and other elements to form the final battery pack. This is the last stage for battery production, ensuring it meets all functional and safety standards. Key processes in BATTERY PACK assembly include: module fixation, liquid cooling system integration, EOL (End-of-Line) testing, accessory installation and airtightness testing.
The technological evolution of
battery MODULE and PACK welding and assembly lines is driving the overall advancement of battery manufacturing for electric vehicles. Assembly lines are increasingly moving toward high levels of automation to meet the rapidly growing market demand.
