1. A wireless power transmission apparatus, comprising:
- a transmission communication unit receiving a code including a charging status of a battery;
a transmission unit generating and transmitting power for charging the battery;
a transmission control unit detecting the charging status of the battery by using the transmitted power, and, if the charging status of the battery is in a damage section due to reflective power, controlling the transmission unit to transmit power lower than power of a normal operation, and if the charging status of the battery is not in the damage section due to the reflective power, controlling the transmission unit to transmit the power of the normal operation,wherein the damage section due to the reflective power is a section in which a constant current (CC) mode in which the battery is charged constant current is converted into a constant voltage (CV) mode in which the battery is charged with constant voltage.

Abstract
Disclosed herein is a wireless power transmission system, including: a transmission unit generating and transmitting power for charging a battery; a reception unit receiving the transmitted power and charging the battery with power; and a transmission control unit detecting a charging status of the battery by using the transmitted power, and, if the charging status of the battery is in a damage section due to reflective power, controlling the transmission unit to transmit power lower than power of a normal operation, whereby damage of transmission and reception devices due to a reflective wave can be minimized.

7. A method of controlling a wireless power transmission system, the method comprising:
-
generating and transmitting power for charging a battery in a power transmission unit; receiving a code including a charging status of the battery in the power transmission unit; detecting a charging status of the battery by using the transmitted code in the power transmission unit; if the charging status of the battery is in a damage section due to reflective power, controlling power lower than power of a normal operation to be transmitted, and if the charging status of the battery is not in the damage section due to the reflective power, controlling the power transmission unit to transmit the power of the normal operation in the power transmission unit, wherein the damage section due to the reflective power is a section in which a constant current (CC) mode in which the battery is charged with constant current is converted into a constant voltage (CV) mode in which the battery charged with constant voltage. - View Dependent Claims (8, 9, 10, 11, 12)
