DEVICE AND METHOD FOR TRANSMITTING DATA IN WIRELESS POWER TRANSMISSION SYSTEM

The present invention relates to a device and method for transmitting data in a wireless power transmission system. The present specification discloses a wireless power reception device comprising: a power pickup unit configured to receive wireless power from a wireless power transmission device by magnetic coupling with the wireless power transmission device, and convert an AC signal generated by the wireless power into a DC signal; a communication/control unit configured to receive the DC signal from the power pickup unit and perform control of the wireless power; and a load configured to receive the DC signal from the power pickup unit. According to the present invention, a large amount of data can be easily exchanged between a wireless power transmission device and a wireless power reception device by adjusting a transmission time interval of a control error packet (CEP) and a timeout of the CEP.
