Abstract:
A wireless power transmission apparatus and a wireless power transmission method includes: activating a first wireless transmission unit having a first transmission scheme and deactivating a second transmission unit having a second transmission scheme; transmitting power by the first transmission scheme when a reception scheme of a wireless power reception apparatus is same as the first transmission scheme; deactivating the first wireless transmission unit and activating the second wireless transmission unit when the reception scheme is different from the first transmission scheme; and transmitting the power by the second transmission scheme when the reception scheme is same as the second transmission scheme. Interference between the first wireless transmission unit and the second wireless transmission unit can be prevented from occurring by selectively or sequentially activating the first wireless transmission unit and the second wireless transmission unit.
