1. A wired/wireless battery charging apparatus for a portable terminal, the apparatus comprising:
- a body including a wired charging circuit for wired charging a first battery of the portable terminal, a wireless charging circuit for wireless charging a second battery mounted in the portable terminal, and a battery mounting space for mounting the first battery;
a cover removably coupled with the body, the cover including a transmission coil generating a magnetic field for the wireless charging of the second battery; and
a cavity exposed by removing the cover,wherein the body and the cover includes a contact unit for electrically connecting the transmission coil to the wireless charging circuit,wherein the transmission coil is electrically connected with the wireless charging circuit through the contact unit when the cover is closed,wherein the wired charging circuit charges the first battery when the first battery is disposed in the cavity, andwherein the wireless charging circuit charges the second battery when the portable terminal is proximate to the cover.
