Embodiments presented herein are generally directed to techniques for separately transferring power and data from an external device to an implantable component of a partially or fully implantable medical device. The separated power and data transfer techniques use a single external coil and a single implantable coil. The external coil is part of an external resonant circuit, while the implantable coil is part of an implantable resonant circuit. The external coil is configured to transcutaneously transfer power and data to the implantable coil using separate (different) power and data time slots. At least one of the external or internal resonant circuit is substantially more damped during the data time slot than during the power time slot.

The present invention provides a multi-coil inductive power transfer primary comprising a plurality of coil. A power transfer regime is selected based on a determined load on each of the plurality of coils.

A power reception apparatus performs device authentication on a power transmission apparatus, and performs control to request first power of the power transmission apparatus in a case where the power transmission apparatus fails the device authentication and to request second power higher than the first power of the power transmission apparatus in a case where the power transmission apparatus successfully passes the device authentication. In addition, the power reception apparatus sets a setting to permit requesting the second power of a power transmission apparatus which does not have a function for responding to the device authentication.

A method for determining the relative position of a metal object in relation to a user device and to a transmitter antenna of an inductive charging support when charging the user device. The method includes measuring the quality factor of the transmitter antenna, measuring the quality factor of the receiver antenna, and comparing the measured quality factor of the transmitter antenna with a predetermined quality factor threshold of the transmitter antenna and comparing the measured quality factor of the receiver antenna with a predetermined quality factor threshold of the receiver antenna so as to deduce therefrom the relative position of the metal object in relation to the user device and to the transmitter antenna or the absence of an interfering metal object.

Systems, methods and apparatus for wireless charging are disclosed. A method for receiving power from a charging surface includes obtaining a combined current by combining currents induced in a plurality of receiving coils provided on a surface of the chargeable device in a first mode of operation, rectifying the combined current to obtain a battery charging current, and providing the battery charging current to a battery coupled to the chargeable device. In one example, the currents are induced through electromagnetic coupling by coils in a charging surface of a wireless charging device.
