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.
