Abstract

A contactless charging method according to the present invention is applied to a contactless charging system (1) which comprises a transmitting unit (10) having a primary coil (11) and a receiving unit (20) having a secondary coil (21) and which charges a battery (30) electrically connected to the secondary coil (21) by the electromagnetic induction generated between the primary coil (11) and the secondary coil (21) and which supplements the charging efficiency of the battery (30) by varying the charging efficiency used in the electromagnetic induction in proportion to the charging efficiency of the battery (30) that varies according to the position of the secondary coil (21) relative to the primary coil (11). The contactless charging method comprises: a step of detecting a charging frequency when a charging operation is performed by enabling the primary coil (11) to get closer to the secondary coil (21); and a step of outputting the charging efficiency of the battery (30) acquired from the detected charging frequency such that a user may know the charging efficiency.
