METHOD OF CHARGING A MOBILE TERMINAL BY A MOBILE DEVICE FOR ONBOARDING ON A MOTOR VEHICLE AND RELATED CHARGING DEVICE

摘要

The present invention relates to a charging method of a mobile terminal by a charging device (D) intended to be embedded in a motor vehicle, the charging device (D) comprising at least one inductive primary antenna (B1). WPC "having a charging frequency and a second resonant primary antenna (B2)" A4WP "having a resonant frequency (RF), at least 1000 times higher than the charging frequency, a ferromagnetic body (C) underneath and in solidarity of the inductive primary antenna, the invention proposing that the method consists in: • previously equipping the ferromagnetic body and the inductive primary antenna with displacement means (100) able to move the ferromagnetic body and said primary inductive antenna with respect to to the resonant primary antenna, • to move (steps E1 and E1a) the ferromagnetic body associated with the primary inductive antenna with respect to the primary resonant antenna e, as a function of the resonant frequency (RF) of said resonant primary antenna when the mobile terminal is loaded by the resonant primary antenna and • to move (steps E2 and E2a) the ferromagnetic body associated with the antenna inductive primary as a function of the charging efficiency (Q) of the inductive primary antenna when the mobile terminal is charged by the inductive primary antenna.
