(EN) BATTERY SYSTEM WITH A CELL CONNECTING UNIT
(FR) SYSTÈME DE BATTERIE PRÉSENTANT UNE UNITÉ DE CONNEXION DE CELLULES
Abstract
(EN)
The present invention refers to a battery system (300) which comprises a cell stack (20), wherein at least two battery cells (10) of the cell stack (20) are electrically interconnected via a battery cell connector (90). The battery system (30) comprises a printed circuit board, PCB (150), and a cell connecting unit, CCU (140). The battery cell connector (90) is accommodated in the CCU (140), the CCU (140) being fixed onto the cell stack (20) and comprising one first flexible bracket (145) that is inserted into a corresponding mounting hole (151) of the PCB (150). According to the invention, the first flexible bracket (145) of the CCU (140) comprises a member (146) configured to fix the PCB (150) to the CCU (140) after the member (146) has been molten in a state in which the first flexible bracket (145) was inserted into the corresponding mounting hole (151).
