Abstract
A wireless power transmission method of a wireless power transmission apparatus having a plurality of power transmission schemes can include a first detection step including transmitting a first detection signal for a first power transmission scheme and detecting a first response signal corresponding to the first detection signal during a first predetermined time period; a second detection step including transmitting a second detection signal for a second power transmission scheme and detecting a second response signal corresponding to the second detection signal during a second predetermined time period; a determination step determining a power transmission scheme of an wireless power reception apparatus between the first power transmission scheme and the second power transmission scheme; and a power transmission step transmitting a power to the wireless power reception apparatus through the power transmission scheme.
