CURRENT COLLECTOR, BATTERY MODULE WITH A CURRENT COLLECTOR AND USAGE THEREOF

摘要

Current collector (21) for a battery module, comprising an elongated, electrically conductive structure with two ends, having a main terminal (31) at a first end of the conductive structure, and a last cell bus bar terminal (45) the second end of the conductive structure, and a first cell bus bar terminal (41) between the main terminal (31) and the last cell bus bar terminal (45), and the conductive structure has an initial cross section (25) at the main terminal (30), and the conductive structure has a first cross section (26) at the first cell bus bar terminal, and the conductive structure has a final cross section (27) at the last cell bus bar terminal, wherein the initial cross section (25) is larger than the final cross section (27), and the first cross section (26) is larger than the final cross section (27) but not larger than the initial cross section (25).
