Controlling inductive charging of a portable item of user equipment by a charging device. The charging device including a reception surface receiving the item of user equipment, emitter coils and a magnetic field guide to direct a magnetic field in a plane parallel to the reception surface. The charging device equipped with at least two magnetic antennas, each to emit a magnetic field and each designed to partially receive the magnetic field emitted by the other antenna. The method includes the following steps: Simultaneous emission by the two antennas, having a first phase shift at input with respect to one another; Measurement of at least one parameter at the output of the antennas; Storage of the measured parameter; Comparison between the at least one parameter thus measured and a predetermined value; Repetition of the preceding steps for other phase shift values; Controlling of the charging based on the comparison results.

Method for controlling the inductive charging of a user device and associated charging device for motor vehicle

A device for high-frequency communication and for the inductive charging of an apparatus, including a charging surface, at least one charging antenna emitting a magnetic field at a low frequency and a layer of ferromagnetic material. The device includes at least one communication antenna and a printed circuit board. The communication antenna is in the form of a coil locally surrounding the layer with an axis of symmetry located in a plane parallel to the layer. The material of the layer is selected so as to have, at high frequency, an imaginary part with sufficiently high permeability to generate leaks on a surface of the layer extending perpendicular to the layer, while at the same time maintaining, at low frequency, an imaginary part with sufficiently low permeability to allow inductive charging.

Apparatus for high-frequency near-field communication and for inductively recharging a portable electronic device

A device for high-frequency communication and for the inductive charging of an apparatus, including a charging surface, at least one charging antenna emitting a magnetic field at a low frequency and a layer of ferromagnetic material. The device includes at least one communication antenna and a printed circuit board.
