Abstract: A pad assembly for power reception of an electric vehicle includes a receiving pad configured to support a receiving coil connected to an external component, and a magnetic complex layer disposed above or below the receiving coil. An increment in inductance per unit density of the magnetic complex layer disposed above or below the receiving coil is 25%·cm3/g or more compared to an increment in inductance per unit density of the magnetic complex layer alone not disposed above or below the receiving coil.

Abstract: A wireless power receiver includes a receiving pad configured to receive power transmitted from a wireless power transmitter including a transmitting pad and a transmitting side resonant inductor, and a receiving side resonant network including a receiving side resonant inductor that controls power supplied to the receiving pad. Further, a first inductance of the receiving side resonant inductor and a second inductance of the transmitting side resonant inductor are determined to be different from each other.
