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.
