CELL CONNECTION UNIT, CCU, FOR A BATTERY MODULE

摘要

The present invention relates to a cell connection unit (50), CCU, for connecting a plurality of aligned battery cells (10) of a battery module (70), wherein the CCU (50) comprising a plurality of busbars (20) and a plurality of carrier rails (30). Therein, each busbar (20) is configured to be connected to cell terminals (11,12) of at least two battery cells (10) and at least some of the carrier rails (30) are configured to be mechanically connected to at least three busbars (20). Further, the at least some of the carrier rails (30), particularly inset carrier rails (37), comprise a first reception region (31) configured to be connected to at least one busbar (20) and a separate second reception region (32) configured to be connected to two busbars (20) and to electrically insulate the connected two busbars (20) from each other. The present invention further relates to a battery module (70) with the CCU of the invention.
