The present invention relates to a system for rating output according to the sensing of wireless charging efficiency. The system includes: a power transmission unit impedance detection unit detecting an impedance value of a power transmission unit; a power reception unit impedance detection unit detecting an impedance value of a power reception module; a transmission power detection unit detecting output power finally supplied from the power transmission unit to the power reception module; an MCU calculating a rating voltage or current based on the impedance value of the power transmission unit, the impedance value of the power reception module, and the output power; a rating voltage/current transmission unit receiving the rating voltage or current calculated by the MCU; and a power supply control unit increasing the voltage or current of the power transmission unit based on the rating voltage or current value of the rating voltage/current transmission unit. Therefore, the present invention is capable of maintaining wireless charging efficiency continuously in the best condition.
