6 FAQs about [Battery Pack Welding Inspection Standard Specification]

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.

What is weld quality testing of lithium-ion batteries?

Several components of lithium-ion batteries - electrode metal foils (current collectors), tabs and output terminals - are welded together using technologies such as laser or ultrasonic welding. If these welds are inadequate, the electrical resistance between components will increase.

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.
