Abstract
A non-contact type power charging apparatus may include a plurality of power transmitting coils transmitting power in a non-contact scheme, a plurality of switching units connected to the power transmitting coils, respectively, to switch the power transmitted through corresponding power transmitting coils, and a switching controlling unit controlling power switching of the switching units depending on coupling coefficients between each of the power transmitting coils and at least one power receiving coil of a plurality of battery apparatuses. The battery apparatuses may have at least one power receiving coil receiving the power from the power transmitting coils to charge the power in at least one battery cell.

A non-contact type power charging apparatus comprising:
- a plurality of power transmitting coils transmitting power in a non-contact scheme;
- a plurality of switching units connected to the power transmitting coils to switch the power transmitted through corresponding power transmitting coils;
- and
- a switching controlling unit controlling power switching of the switching units depending on coupling coefficients between each of the power transmitting coils and at least one power receiving coil of a plurality of battery apparatuses receiving the power from the power transmitting coils to charge the power in at least one battery cell.
A non-contact type power charging apparatus comprising:
- a plurality of power transmitting units each including:
- a power unit supplying a direct current (DC) voltage,
- a switching unit switching the DC voltage from the power unit,
- a power transmitting coil transmitting power in a non-contact scheme depending on power switching of the switching unit,
- a detecting unit detecting power state variations of the power transmitting coil, and
- a controlling unit controlling the power switching of the switching unit by setting a coupling coefficient between the power transmitting coil and a power receiving coil depending on a detection result of the detecting unit,
- wherein the plurality of power transmitting units control transmission power depending on coupling coefficients between the power transmitting coils of each of the power transmitting units and at least one power receiving coil of a plurality of battery apparatuses receiving the power from the power transmitting coils to charge the power in at least one battery cell.
