1. A wireless charging device, comprising:
- a first block coil to transfer wireless power;
a first power source to provide the first block coil with a current for generating a first wireless power;
a first switch to connect the first power source with the first block coil; and
a controller to determine whether the first block coil is a valid block coil for a first chargeable terminal, and to control the first switch to connect the first power source with the first block coil if the first block coil is determined as a valid block coil for the first chargeable terminal.

Abstract
A method for operating a wireless charging device includes detecting a chargeable terminal, detecting a valid block coil according to information transmitted from the chargeable terminal, switching on the valid block coil, and controlling a current supply to the valid block coil. A terminal includes a receiving coil configured to induce a current in response to receipt of wireless power, an induced voltage detection unit to measure an induced voltage generated by the induced current, and to generate induced voltage information, and a communication unit to transmit the induced voltage information to a wireless charging device.
