6 FAQs about [The role of the battery pack welding protection board]
Are welds good for battery packs?
Having made repeated across-the-board improvements to boost battery pack performance, the company has shifted its focus in recent years to improving the quality of welds in batteries. Welds are used in a variety of joining steps throughout the battery cell and battery pack manufacturing process.
Why are welds important?
Welds are used in a variety of joining steps throughout the battery cell and battery pack manufacturing process. Defects in the quality of welds that involve electrical circuits are particularly critical insofar as they can prevent the battery cell and battery pack from realizing its full performance.
Are there accessibility issues with battery welding?
This means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.
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.
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.
Is LW a good process for assembling battery packs?
Despite these challenges, from a practical point of view, LW still seems to be the preferred process for assembling battery modules and packs, as it does not require two-sided access or extremely rigid fixtures like the single-sided versions of UW and RSW, and of course, it offers high processing speeds to keep up with high production rates.
