A power transmission device includes a communication module for transmitting and receiving a power transmission packet, which is an information packet related to the settings of the power transmission, and a general packet, which is an information packet other than the power transmission packet, to and from the power reception device; and a power transmission module for performing the power transmission after transmission and reception of the power transmission packet. The communication module receives address information indicating an address configuration of the memory from the power reception device; provides the general packet with address designation indicating a first memory area, and provides the power transmission packet with address designation indicating a second memory area, on the basis of the address information; and transmits the general packet and the power transmission packet having the address designation to the power reception device.
