BATTERY MODULE WITH FLEXIBLE INTERCONNECTOR

The present invention refers to a battery module (50), comprising a plurality of aligned battery cells (10) with surfaces of different orientation and a cell supervision circuit (20), CSC, configured to receive signals corresponding to the voltage and/or temperature of at least one battery cell (10). A flexible interconnector (30) of the battery module (50) comprises a strip-shaped flexible printed circuit (35), FPC, with a first insulating main surface (31), a second insulating main surface (32) opposite the first insulating main surface (31) and a plurality of thermally and/or electrically conducting lines (33) disposed between the first insulating main surface (31) and the second insulating main surface (32). Each conducting line (33) comprises at least one contact portion (34) that is exposed by a contact aperture (36) in the first insulating main surface (31) and/or the second insulating main surface (32) and further comprises at least one connecting portion (37) for being connected to the CSC (20). According to the invention, the flexible interconnector (30) is wrapped around the plurality of aligned battery cells (10) such that the contact portions (34) contact the surfaces of different orientation, preferably in a method for manufacturing a battery module (50) of the invention.
