CONTACTLESS RECHARGEABLE BATTERY CAPABLE OF LESSENING POWER LOSS AND BATTERY CHARGING SET HAVING THE SAME

摘要

The present invention relates to a contactless rechargeable battery having an embedded charging circuit for charging a battery cell with an electrical energy, comprising a high frequency alternating current inducing unit, in which a high frequency alternating current is induced by a magnetic field generated in an external contactless charger; a charging voltage supply unit for supplying voltage necessary to charge the battery cell; a charging current supply unit for supplying the battery cell with a charging current using the voltage applied from the charging voltage supply unit; and a charging current monitoring unit for monitoring a value of the current supplied by the charging current supply unit, and transmitting the monitoring results to the external contactless charger through a wireless communication to induce change of intensity of the magnetic field.
