摘要： The present invention relates to an apparatus and a method for performing wireless power transmission on the basis of foreign material detection. The present specification provides a wireless power reception apparatus comprising: a power pick-up unit configured to receive wireless power from a wireless power transmission apparatus by magnetic coupling with the wireless power transmission apparatus and convert an AC signal generated by the wireless power into a DC signal; a communication/ control unit configured to receive the DC signal from the power pick-up unit and control the wireless power; and a load configured to receive the DC signal from the power pick-up unit. When foreign material is detected before power transmission, wireless power transmission is sustained on the basis of a safe basic power profile of 5 W or less, without interrupting power transmission, and thus, a charging delay can be prevented and the accuracy and reliability of detection of foreign material can be increased despite individual characteristics of the wireless power reception apparatus.

摘要： A wireless power transmission apparatus includes a shielding plate, a transmission coil on the shielding plate, and a shielding member disposed on the shielding plate and configured to surround the transmission coil. The shielding plate may shield a magnetic field formed to a lower side of the transmission coil. The shield member can offset the magnetic field formed on the side of the transmission coil. Thus, the embodiment can minimize EMI or EMF caused by the magnetic field formed on the lower side and the side of the transmission coil.
