A wireless charging system includes a first power receiving device connected in parallel to a first battery and including a first sub resonant circuit having a first resonant frequency, a second power receiving device connected in parallel to a second battery and including a second sub resonant circuit having a second resonant frequency, and a power transmitting device. The power transmitting device is for determining a charging order between the first battery and the second battery. The power transmitting device wirelessly transmits first alternating current (AC) power having the first resonant frequency to the first sub resonant circuit when the first battery is selected according to the charging order and wirelessly transmits second AC power having the second resonant frequency to the second sub resonant circuit when the second battery is selected according to the charging order.
