Method and apparatus for wirelessly transmitting power and power transmission information
First Claim
1. A method of operating a wireless power transmission apparatus, the method comprising:
- receiving, from a wireless power reception apparatus, information on an operating power of the wireless power reception apparatus and information on an output of a direct current-to-direct current (DC/DC) converter of the wireless power reception apparatus;
determining whether a charging power is to be transmitted to the wireless power reception apparatus based on the received information on the output of the DC/DC converter; and
transmitting, to the wireless power reception apparatus, an operating power calculated based on the received information on the operating power of the wireless power reception apparatus in response to a determination that the charging power is not to be transmitted to the wireless power reception apparatus.
