Definitions
- the method further includes:
- Fig. 8 is a block diagram showing a wireless charging device according to another exemplary embodiment
- At least two power levels are preset, and each power level contains at least one candidate transmission power.
- power level includes power level 1 and power level 2
- power level 1 includes 3 candidate transmission powers, 5W, 10W, and 15W
- power level 2 includes 2 candidate transmission powers. They are 20W and 30W respectively.
- step 304 in the process of charging with the second transmission power, the second power loss is obtained.
- the power transmission device continues to detect the power loss after it is adjusted from the first transmission power to the second transmission power. At this time, the power loss acquired by the power transmission device is recorded as the second power loss.
- the method for the power transmission device to obtain the power loss has been introduced above, and will not be repeated here.
- the power transmitting device sends a power recovery message to the power receiving device, and the power recovery message is used to trigger a notification that the first transmission power has been resumed for charging.
- the power receiving device After receiving the power recovery message, the power receiving device sends a power recovery notification, and the power recovery notification is used to notify the user that the first transmission power has been resumed for charging.
- the power receiving device may display the power recovery notification in graphic form on the display screen, or may play the power recovery notification in voice form through the speaker, which is not limited in the embodiment of the present disclosure.
- step 308 if the third power loss is greater than the third threshold, the second transmission power is used to charge the power receiving device, and the first transmission power is no longer restored.
- the transmitter/receiver 1002 is used to support communication between the power receiving device 1000 and other devices (such as a power transmitting device and/or other power receiving devices).

Abstract
La présente invention concerne un procédé et un appareil de charge sans fil et un support d'informations et appartient au domaine technique de la charge sans fil. Le procédé comprend les étapes suivantes : un dispositif d'envoi de puissance charge un dispositif de réception de puissance avec une première puissance d'envoi ; dans le processus de charge avec la première puissance d'envoi, l'obtention d'une première perte de puissance ; si la première perte de puissance est supérieure à un premier seuil, la charge du dispositif de réception de puissance avec une seconde puissance d'envoi qui est inférieure à la première puissance d'envoi. Dans des modes de réalisation de la présente invention, lorsque le dispositif d'envoi de puissance détecte que la perte de puissance est supérieure à un certain seuil, la puissance d'envoi est réduite ; d'une part, le risque potentiel de sécurité provoqué par une surchauffe de corps étrangers en un court laps de temps en raison d'une puissance d'envoi excessive peut être évité afin d'améliorer la sécurité et la fiabilité de la charge sans fil ; d'autre part, le dispositif de réception de puissance peut être chargé en continu et une interruption de charge est évitée, ce qui permet d'améliorer la continuité de la charge sans fil.
