Abstract
Official abstract text for this publication.
Provided are a method for welding a battery module and a welded structure, and more particularly, a method for welding a battery module and a welded structure, in which a plurality of battery cells provided with electrode tabs are assembled to form a module and a voltage measurement portion of a voltage measurement means is welded to the electrode tabs so as to secure stability against vibrations and external shocks, thereby increasing reliability of voltage measurement and the voltage measurement portion is welded to the electrode tabs using the same kind of materials so as to facilitate an operation and improve productivity.
First claim
Opening claim text (preview).
The invention claimed is: 1. A battery module comprising: a plurality of battery cells, each battery cell having first and second electrode tabs made of different materials; and a voltage measurement means provided with a plurality of voltage measurement portions made of the same material as the first electrode tab, wherein the first and second electrode tabs are welded at a welded surface formed by contacting each other and the voltage measurement portion is welded with the fir…
