Abstract: The present invention relates to a method and apparatus for performing position estimation of multiple receiving coil and wireless power transmission. A method for performing wireless power transmission according to an embodiment of the present disclosure may comprise: calculating a current value flowing through one or more transmitting (Tx) coils by measuring an impedance value of the one or more Tx coils; identifying whether a receiving (Rx) coil associated with the one or more Tx coils exists; when one or more Rx coils exist, calculating a correlation value between a Tx coil and a Rx coil for each of the one or more Rx coils; determining a position of the one or more Rx coils; and performing wireless power transmission to the one or more Rx coils.
