1. An apparatus, comprising:
- a power receiving unit configured to receive power wirelessly;
a charging unit configured to receive the power via the power receiving unit; and
a controller configured to;
detect output capacity of the power receiving unit at a predetermined interval such that a charging efficiency is maintained at maximum while power is supplied to a battery;
change an output voltage of the power supplied to the battery in real time based on the detected output capacity; and
cause charging of the battery via the charging unit at the changed output voltage.

Abstract
Disclosed is a wireless power receiving apparatus for wirelessly receiving power. The wireless power receiving apparatus includes a power receiving unit configured to wirelessly receive power, a charging unit configured to receive the power from the power receiving unit, and supply the power to a battery, and a control unit configured to determine an output voltage, which enables a charging efficiency of power, supplied to the battery, to be the maximum, based on an output capacity output from the power receiving unit, and control the power receiving unit for the battery to be charged with the output voltage.
