According to one embodiment, the electronic device 201 may acquire an image including a device for providing wireless power through the camera 205. The electronic device 201 may display the image and the object overlapping the image through the display 203.

According to one embodiment, the electronic device 201 may receive power wirelessly. For example, the electronic device 201 may receive power without contacting a device for providing wireless power. For example, the electronic device 201 may be charged through electromagnetic waves generated from a device for providing wireless power. Due to the spreading phenomenon of electromagnetic waves, the electronic device 201 can be charged with higher charging efficiency the closer it is to a device for providing wireless power.

According to one embodiment, the device for providing wireless power may identify that the electronic device 201 is nearby. The device for providing wireless power may transmit a control signal to start charging to the electronic device 201 as the electronic device 201 approaches. The device for providing wireless power may specify the electronic device 201.

According to one embodiment, the processor 207 may identify that a current exceeding a reference value flows through the power receiving circuit 209 in the electronic device 201. The power receiving circuit 209 may refer to a charging circuit. For example, the processor 207 may connect the electronic device 201 and a device for providing wireless power based on identification of a current greater than the reference value flowing in the charging circuit (e.g., the power receiving circuit 209).

The device for providing wireless power may identify relative location information between the device for providing wireless power and the electronic device 201 based on the plurality of distances. The device for providing wireless power can transmit the location information by transmitting a signal to the electronic device 201. The processor 207 may identify charging efficiency information of the electronic device 201 for the device for providing wireless power. The charging efficiency information may be identified based on the current flowing in a charging circuit (eg, power receiving circuit 209) within the electronic device 201. The charging efficiency information of the electronic device 201 may include electrical energy charged per unit time. For example, the charging efficiency information may include charging power.

For example, at the time of pre-charging of the electronic device 201, the longer the distance between the electronic device 201 and the device for providing wireless power, the wider the charging area may be formed. At the time of preliminary charging, a current greater than a reference value may flow in the electronic device 201 to a charging circuit (e.g., power reception circuit 209) within the electronic device 301. The closer the distance between the electronic device 201 and the device for providing wireless power, the higher the charging efficiency. At the time of pre-charging of the electronic device 201, the distance between the electronic device 201 and the device for providing wireless power may be referred to as the pre-charging distance. The longer the preliminary charging distance, the wider the area where charging efficiency is greater than the first threshold. The processor 207 may obtain an image including a device for providing the wireless communication through the camera 205. The processor 207 may display the image and objects overlapping on the image through the display 203. The object may correspond to the at least one charging zone. For example, the objects may be concentric circles centered on a device for providing wireless power. However, embodiments of the present disclosure are not limited thereto. According to one embodiment, the object may be shapes centered on a device for providing wireless power.

According to one embodiment, there may be an obstacle between the electronic device 201 and the device for providing wireless power. When there is an obstacle between the electronic device 201 and the device for providing wireless power, the processor 207 provides approximate location information (e.g., direction and/or distance) of the device for providing wireless power. can be displayed.

According to one embodiment, the electronic device 201 may perform wireless charging through the power reception circuit 209. The power reception circuit 209 may perform wireless charging using electromagnetic waves transmitted by a device for providing wireless power through a power transmission circuit.

According to one embodiment, the short-range communication module 211 may transmit a control signal to a device for providing wireless power. For example, the control signal may include distance information between the electronic device 201 and a device for providing wireless power. For example, the control signal may include charging efficiency information of the electronic device 201. The processor 207 may identify the at least one charging zone based on the distance information and the charging efficiency information. The processor 207 may receive a notification signal from a device for providing wireless power through the short-range communication module 211. The notification signal may include information about a control signal from another external electronic device. For example, the notification signal may include distance information between another electronic device and the device for providing wireless charging. For example, the notification signal may include charging efficiency information of another electronic device. According to one embodiment, the processor 207 is configured to store the distance information of the electronic device 201, the charging efficiency information of the electronic device, the distance information of the other electronic device, and the charging efficiency information of the other electronic device. Based on this, the at least one charging zone can be identified. For example, the higher the charging efficiency of the other electronic device, the smaller the charging area of the electronic device 201 may be. This is because the electronic device 201 and the other electronic device must be charged simultaneously with the same power.

The charging distance 513 may be the distance between the electronic device 505 and the device 501 for providing wireless power. For example, if the distance in the pre-charge state is 1.5 meters (meter) and the charging efficiency is about 20%, the electronic device 503 or 505 can identify the distance at which the charging efficiency is about 90%. This is because the closer the distance is, the higher the charging efficiency can be. The first zone may be a zone where charging efficiency is about 90% or more.

The charging efficiency of the electronic device 603 at the charging distance 607 may be greater than the charging efficiency of the electronic device 605 at the charging distance 613.

According to one embodiment, the radius 611 of charging zone 609 may be equal to the radius 617 of charging zone 615. For example, the threshold for determining charging zone 609 may be about 90%, and the threshold for determining charging zone 615 may be about 70%. That is, the electronic device 603 may display a charging zone corresponding to a charging efficiency greater than the threshold for the electronic device 603.
