APPARATUS FOR CHARGING THE BATTERY OF A MOBILE TERMINAL WITHOUT A WIRE CONNECT

摘要

The present invention relates to a wireless charging apparatus for a portable terminal. The wireless charging apparatus comprises: an electromagnetic generator with a primary coil generating an electromagnetic field; and an inductive charger generating inductive current due to the electromagnetic field of the electromagnetic generator to charge a battery. The conductive charger comprises: a case where the portable terminal is detachably mounted; a secondary coil included in the case and generating inductive current due to the electromagnetic field of the primary coil when positioned at the electromagnetic generator; a conversion unit connected with the secondary coil and converting the conductive current induced in the secondary coil to be charged; an auxiliary battery included in the case; a switching unit connected with the conversion unit and performing switching to allow the inductive current converted in the conversion unit to be supplied to the portable terminal or to the auxiliary battery or to allow current charged in the auxiliary battery to be supplied to the portable terminal; a first connector connecting the switching unit with the portable terminal; and a second connector connecting the switching unit with the auxiliary battery. According to the present invention, the battery of the portable terminal can be conveniently charged. In addition, when the battery of the portable terminal is discharged, the battery can be easily charged.
