Abstract

L’invention concerne un procédé de détection d’un objet à charger, par un dispositif de charge (D’), comprenant une bobine émettrice (B1), un microcontrôleur (10’) adaptés pour charger à une fréquence de fonctionnement (FRF), un équipement portable d’utilisateur (P), le procédé étant caractérisé en ce qu’il comprend les étapes suivantes : a) Emission d’un nombre prédéterminé (N) d’impulsions de tensions (P1) aux bornes de la bobine émettrice (B1), à une fréquence de résonance parasite (FRP), comprise dans une fenêtre de valeurs, ladite fréquence de résonance étant différente et distincte de la fréquence de fonctionnement (FRF), b) Mesure de la tension (VB1) aux bornes de la bobine émettrice (B1), c) Comparaison entre une fréquence de la tension (FB1) ainsi mesurée et ladite fenêtre de valeurs, d) Si la fréquence de la tension (FB1) est comprise dans ladite fenêtre de valeurs, alors détection d’un équipement portable d’utilisateur (P) à charger.
