1. A contact-less chargeable battery including a charging circuit for charging an electric energy to a battery cell, the contact-less chargeable battery comprising:

  • a high frequency AC current inducing unit to which a high frequency AC current is induced by means of a magnetic field generated from an external contact-less charging device;

    a rectifier for receiving the induced high frequency AC current and converting the induced high frequency AC current into a DC current;

    a constant voltage/constant current supplier for receiving the DC current from the rectifier and supplying a charging power to the battery cell in a constant voltage/constant current mode; and

    an overvoltage monitoring unit for monitoring voltages at both ends of the constant voltage/constant current supplier and transmitting a monitoring result to the external contact-less charging device by means of wireless communication so as to induce a change of intensity of the magnetic field.
