An electronic device is includes battery; coil; wireless charging circuit electrically connected to coil; power management module configured to control charge state of battery by using power supplied from receiving circuit; and processor operatively connected to wireless charging circuit and power management module, wherein processor is configured to request configuration information for performing wireless charging from external device through the wireless charging circuit; determine whether wireless charging is possible, based on a response to the request for configuration information; when the wireless charging is possible, request encrypted authentication information from the external device so as to perform authentication with respect to the external device; when the external device is an unauthenticated device, request the external device to transmit a first predetermined power; and when the external device is an authenticated device, request the external device to transmit a second predetermined power that is higher than the first predetermined power.

Data communication method for wireless charging and electronic device using same

An electronic device includes a housing including a first plate, a second plate spaced apart from the first plate and facing the first plate, and a side member at least partially surrounding a space between the first plate and the second plate, a display located in the space and visible through the first plate, a conductive coil parallel to the second plate and disposed between the display and the second plate, a wireless charging circuit electrically connected to the conductive coil, and a processor operationally connected with the display and the wireless charging circuit. The processor receives a power control signal from an external device, applies a charging current to the conductive coil, based on the power control signal, senses whether a specified event occurs while the charging current is applied, and when the specified event occurs, transmits information for setting a charging power corresponding to the specified event to the external device.

Electronic device for wireless charging external device

Various embodiments of the present invention relate to an apparatus and a method for controlling battery charging in an electronic device. The electronic device comprises a plurality of temperature sensors disposed at different positions, a battery, a memory, at least one processor, and a charging module for controlling charging of the battery, wherein the charging module may be configured to identify a charging type of the battery, to select at least one temperature sensor among the plurality of the temperature sensors based on the charging type of the battery, and to control a charging current of the battery based on a temperature measured through the at least one temperature sensor. Other embodiments may be possible.
