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).
