Abstract

A foreign object detection apparatus (200) including a plurality of object sensing devices (201a, 202b,..., 201n) positioned between a transmission pad and a reception pad of a wireless charging system; and a detection circuit (270) configured to determine whether a foreign object is present between the transmission pad and the reception pad based on data received from the plurality of object sensing devices (201a, 202b,..., 201n). Further, each of the plurality of object sensing devices (201a, 202b,..., 201n) includes a first coil unit (210a) wound with a first coil in a first direction, and a second coil unit (210b) wound with a second coil in a second direction different from the first direction; and the first coil unit (210a) and the second coil unit (210b) overlap each other.
