(FR) DISPOSITIF RÉCEPTEUR D'ÉNERGIE SANS FIL ET SON PROCÉDÉ DE COMMANDE
Abstract
(EN)
An electronic device acting as a power receiving device and a control method. The electronic device includes a battery, a coil, a reception circuit electrically connected to the coil, a charger a current sensing circuit, and at least one control circuit. The charger supplies a specified voltage to a system and controls the state of charge of the battery by using the voltage supplied from the reception circuit. The current sensing circuit is configured to sense an inrush current caused by the system. The at least one control circuit is configured to transmit a first control signal for requesting to increase a transmission voltage supplied from an external electronic device when an inrush current is detected through the current sensing circuit.

L'invention porte sur un dispositif électronique servant de dispositif de réception d'énergie, et sur son procédé de commande. Le dispositif électronique comprend une batterie, une bobine, un circuit de réception connecté électriquement à la bobine, un chargeur, un circuit de détection de courant et au moins un circuit de commande. Le chargeur fournit une tension spécifiée à un système et commande l'état de charge de la batterie à l'aide de la tension fournie par le circuit de réception. Le circuit de détection de courant est configuré pour détecter un courant d'appel provoqué par le système. Ledit circuit de commande est configuré pour transmettre un premier signal de commande servant à demander l'augmentation d'une tension de transmission fournie par un dispositif électronique externe lorsqu'un courant d'appel est détecté à travers le circuit de détection de courant.
