Wireless power transmission system and method of controlling the same

摘要

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.

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.
