6 FAQs about [Assembly and welding of new energy battery equipment]

What are the different welding techniques for batteries?

Do high-volume production requirements affect welding performance in battery assembly?

Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.

How are battery cells welded?

Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.

Is UWB suitable for welding a cylindrical battery cell?

UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.

How much energy does the battery pack assembly process consume?

The energy consumption of the battery pack assembly process was only 0.03 kWh/kg during the battery pack production . Figure 2. Current and future direct costs of BEVs and ICEVs . However, the assembly of a battery pack is a critical process for the major OEMs.
