Abstract
A battery module includes: a plurality of aligned battery cells having differently-oriented surfaces; a cell supervision circuit (CSC) configured to receive signals corresponding to the voltage and/or temperature of at least one of the battery cells; and a flexible interconnector comprising a strip-shaped flexible printed circuit (FPC). The FPC includes a first insulating main surface, a second insulating main surface opposite the first insulating main surface, and a plurality of thermally and/or electrically conducting lines between the first insulating main surface and the second insulating main surface. Each of the conducting lines has a contact portion exposed by a contact aperture in the first insulating main surface and/or in the second insulating main surface and a connecting portion for connection to the CSC, and the flexible interconnector wraps around the battery cells such that the contact portions contact the differently-oriented surfaces of the battery cells.
