In essence, welding battery terminal tabs is a pivotal and intricate process within battery manufacturing. It ensures both the functionality and the visual allure of the final product.
When welding terminals or busbars, sheets with a thickness of up to 5 mm are welded together. These are used when high currents have to be transmitted, as for example in battery management systems or high-current contacts.
Using the example of two battery cells connected in parallel, Fig. 1 illustrates the influence of the quality of cell connections on a battery assembly. The higher electrical contact resistance R C,1 generates more heat at the terminal of cell 1. Additionally, the total current I ges is divided unequally. These uneven loads may lead to inhomogeneous cell degradations.
