1. A non-contact power charging system, comprising:

  • a non-contact power transmission apparatus generating a power signal at a primary charge core thereof; and

    a non-contact power receiving apparatus receiving the power signal from the non-contact power transmission apparatus so as to be charged with power by the control of the non-contact power charging system, wherein the non-contact power receiving apparatus comprises;

    a secondary charge core generating induced current in response to the primary charge core of the non-contact power transmission apparatus;

    a rectifier block connected to the secondary charge core to rectify the induced current;

    a charge IC block causing to charge a battery cell with the power from the rectifier block;

    a received power monitor module monitoring the power received through the secondary charge core; and

    a power receiver control unit constructed to control the rectifier block, the charge integrated circuit block and the received power monitor module, and to control identifier generation and a charge status signal,wherein the received power monitor module includes a low voltage monitor module comparing and discerning whether or not the received power is detected to have a low voltage and a high voltage monitor module comparing and discerning whether or not the received power is detected to have a high voltage.
