Abstract:
An embodiment of the present invention provides a wireless charging apparatus and a method, in which a reception unit can charge even when an inner coil of the reception unit and an inner coil of a transmission unit are not positioned in parallel. An embodiment of the present invention provides a wireless charging apparatus and a method including: a transmission unit that includes a first coil that generates a magnetic field when power is applied; a reception unit that includes a second coil, and that charges a battery using induced current that is induced in the second coil when the magnetic field of the first coil is generated; a position sensing unit that measures position information for the first coil and the second coil; and a conversion unit that converts a direction of the magnetic field according to the position information for the first coil and the second coil.
