METHOD FOR CHARGING A MOBILE TERMINAL WITH A MOBILE DEVICE WITH WHICH A MOTOR VEHICLE IS INTENDED TO BE EQUIPPED AND ASSOCIATED CHARGING DEVICE

A charging device housed on board a motor vehicle includes at least one “WPC” inductive primary antenna, having a charging frequency, and a second “AWP” resonant primary antenna, having a resonant frequency at least 1000 times higher than the charging frequency, a ferromagnetic body situated below and joined to the inductive antenna. The method for charging a mobile terminal includes: equipping the ferromagnetic body and inductive antenna beforehand with a system able to move the ferromagnetic body and inductive antenna with respect to the resonant antenna, moving the ferromagnetic body associated with the inductive antenna with respect to the resonant antenna, depending on the resonant frequency of the resonant antenna when the mobile terminal is charged by the resonant antenna, and moving the ferromagnetic body associated with the inductive antenna depending on the charging efficiency of the inductive antenna when the mobile terminal is charged by the inductive antenna.
