Abstract

The present invention refers to a power transfer system which comprises a power transfer device (10) as well as at least one portable device (20). The power transfer device (10) includes at least one coil arrangement (CA) for generating or receiving a magnetic field, and a first controller (15) coupled to the coil arrangement (CA) for driving the coil arrangement (CA) to supply power to the portable device (20) placed upon the power transfer device (10), via the generated magnetic field. The portable device (20) includes a further coil (23) for generating and receiving a magnetic field, a battery power source (21), and a second controller (22) coupled to the further coil (23) for supplying power received via the magnetic field generated by the power transfer device (10), to charge the battery power source (21). Specifically, the first controller (15) and the second controller (22) are adapted to respectively drive the coil arrangement (CA) of the power transfer device (10) and the further coil (23) of the portable device (20) to establish between the power transfer device (10) and the portable device (20) a near field communication link (NFC link) (32) for transferring data, and a power transfer link (31) for supplying power for charging the battery power source (21) of the portable device (20).
