METHOD AND APPARATUS FOR WIRELESS POWER TRANSMISSION AND WIRELESS POWER RECEPTION APPARATUS

摘要

The present invention relates to a device and a method which wirelessly transmit electric power. According to one aspect of the present invention, a wireless power transmitting device measures an electric current value of a source resonator; receives a charged electric current value, which varies, of a battery from a wireless power receiving device while the battery of the wireless power receiving device is charged; and is able to control electric power quantities to be transmitted by the source resonator based on at least one of the charged electric current value and the electric current value.
