Patent Images
1. A method performed by a wireless charging device for receiving wireless power from a power transmission apparatus, the method comprising:
- entering a hibernation power level detection state as the wireless charging device is turned on;
detecting a power level of the wireless charging device in the hibernation power detection state; and
entering one hibernation state from among a power down hibernation state, a low power hibernation state, and a stable hibernation state, according to the detected power level,starting to receive the wireless power in response to the one hibernation state being the power down hibernation state, and detecting different types of wake-up signals based on whether the one hibernation is the low power hibernation state or the stable hibernation state.

Abstract
This invention defines management protocols for wireless power transfer to multiple devices in Multi-device Wireless Power Management System. Various functions of Multi-device Wireless Power Management System are justified from this invention. The WPT frames and messages which work between the management block of a charger and the management block or the coupler block of a device, or the coupler block of a charger are defined as well to execute various functions. Also the procedures for each functionality are described based on its frames and messages.
