Abstract: The present application relates to a wireless power supply device and wireless power transmission control in an electronic device capable of receiving wireless power. According to an embodiment of the present application, the electronic device capable of receiving wireless power comprises a communication unit which receives power information including at least one piece of electricity bill information and power demand information. Also, the electronic device comprises a wireless power receiving unit which receives wireless power wirelessly supplied from a wireless power supply device, and a power converting unit which converts the wireless power received into power that can be used in the electronic device. Also, the electronic device comprises a control unit which determines occurrence of a power saving section on the basis of the power information received, requests stop of wireless power transmission from the wireless power supply device via the communication unit in the case of occurrence of the power saving section, and requests transmission of wireless power from the wireless power supply device via the communication unit in the case of nonoccurrence of the power saving section. By using various embodiments suggested by the present application, use of power wirelessly supplied can be efficiently controlled, and accordingly, electric power can be economically and efficiently used.
