Abstract
Disclosed are an apparatus and a method for transmitting power wirelessly. The method for transmitting power wirelessly includes: detecting whether a receiving apparatus moves while wirelessly transmitting the power to the receiving apparatus through magnetic inductive coupling; performing the magnetic inductive coupling with the receiving apparatus for each of two or more primary coils when it is detected that the receiving apparatus moves; and determining whether to change the primary coil connected with the receiving apparatus based on a result of the magnetic inductive coupling. A signal strength message received from the receiving apparatus is received and stored every primary coil magnetically inductively coupled with the receiving apparatus, and it is determined that the received apparatus is connected through a primary coil corresponding to a largest value among signal strength values included in the signal strength message.
