    Abstract: A method for connecting a flexible printed circuit (FPC) to a battery module and a cell supervision circuit board (CSCB) is provided. The method includes: providing a coil of a continuous, strip-shaped FPC; unwinding a first section of the FPC from the coil, positioning the first section of the FPC over a first contact portion of the battery module, and welding a conductive structure of the FPC in the first section to the first contact portion of the battery module; unwinding a second section of the FPC from the coil, positioning the second section of the FPC over a contact pad of the CSCB, and welding the conductive structure of the FPC in the second section to the contact pad of the CSCB; and separating the first section and second section of the FPC from the coil of the FPC.

    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.

    Abstract: A battery system includes: a plurality of battery units, each of the battery units including at least one battery cell, the at least one battery cell including a positive terminal, a negative terminal, and a cell case; and a flexible printed circuit (FPC) including a plurality of integrated circuits (ICs) configured for voltage measurement and temperature measurement. The ICs are interconnected by a wiring structure of the FPC. Each of the ICs is thermally connected to the cell case of the at least one of battery cell of each of the battery units via a contact element in the FPC and is electrically connected via the contact element to the positive terminal of the at least one battery cell of each of the battery units.

    Abstract: A battery module includes: a plurality of battery cells; a printed circuit board arranged within a short distance to the battery cells; a passive radio frequency identification tag; and a radio frequency receiver on the printed circuit board. The radio frequency identification tag is attached to at least one of the battery cells and is configured to measure a temperature of the at least one battery cell to which it is attached. The radio frequency identification tag is configured to harvest energy supplied by the radio frequency receiver and to wirelessly send temperature signals corresponding to the temperature of the at least one battery cell within an operating range limited to the short distance. The radio frequency receiver is configured to wirelessly supply energy to the radio frequency identification tag and to receive the temperature signal sent by the radio frequency identification tag.
