Abstract
Provided is a battery charging method using wireless power transmission, the method including: receiving a first message associated with a battery charge start from a reception apparatus; discovering an optimal frequency band for a transmit power signal to be transmitted to the reception apparatus based on the first message; receiving, from the reception apparatus, a second message that includes an extra power value and a charge power value, and is associated with a charge state of the reception apparatus; and adaptively controlling transmit power so that the extra power value is maintained to be constant in proportion to a relationship between the charge power value and a first parameter, based on the second message.
