Method and apparatus for optimizing standby power consumption and providing user indications in WPC based wireless charging system

摘要

In accordance with an example embodiment of the present invention, a method for reducing standby power consumption of a battery of a wireless charging device comprises: monitoring a presence of the wireless charging device nearby a wireless charger transmitter (460); initiating a wireless charging when the presence of the wireless charging device is detected on the wireless charger transmitter (460) and sending a charging notification to an end user; sending a battery full message for notifying the end user when the wireless charging is complete and terminating the wireless charging; setting the wireless charging device to a standby mode and monitoring a ping signal from the wireless charger transmitter (460); entering a maintenance charging mode when the battery is below a recharging threshold without notifying the end user; and continuing the maintenance charging mode of the wireless charging device until the battery is full or the wireless charging device is removed from the wireless charger transmitter (460).

主权项

1. An apparatus, comprising:
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
initiate a wireless charging and send a charging notification to an end user;send a battery full message for notifying the end user when a battery is charged to a full voltage by the wireless charging and terminating the wireless charging;set the apparatus to a standby mode and monitor a ping signal from a wireless charger transmitter to detect whether the apparatus is removed from the wireless charger transmitter;enter a maintenance charging mode without sending the charging notification to the end user, when a voltage of the battery drops from the full voltage to below a recharging threshold; andcontinue the maintenance charging mode of the apparatus until the battery is charged to the full voltage or the apparatus is removed from the wireless charger transmitter.
