Abstract

According to an embodiment of the present disclosure, a method for operating an electronic device may include receiving information related to a second battery from an external electronic device having the second battery by an electronic device having a first battery and a charger for charging the first battery; and identify at least one operation of: 1) receiving an electric power from the external electronic device to the electronic device, 2) supplying an electric power from the electronic device to the external electronic device, or 3) not transferring an electric power between the electronic device and the external electronic device, by the electronic device based at least one of the information related to the second battery or information related to the first battery. Further, various embodiments can be implemented.

First claim

What is claimed is:

1 . A method for operating an electronic device, the method comprising:
receiving information related to a second battery from an external electronic device that includes the second battery by the electronic device that includes a first battery and a charger for charging the first battery; and identifying, by the electronic device, occurrence of at least one operation of (i) receiving an electric power from the external electronic device to the electronic device, (ii) supplying an electric power from the electronic device to the external electronic device, or (iii) not transferring an electric power between the electronic device and the external electronic device based at least one of the information related to the second battery or information related to the first battery.

2 . The method of claim 1 , wherein the information related to the second battery is received using wireless communication between the external electronic device and the electronic device.

3 . The method of claim 2 , wherein the wireless communication comprises a near-field communication.

4 . The method of claim 2 , wherein the information related to the second battery is received using a wireless charging protocol between the external electronic device and the electronic device.

5 . The method of claim 1 , wherein the charger comprises a wireless charger, and the reception or supply of the electric power is performed using the wireless charger.

6 . The method of claim 1 , further comprising:
displaying locations of the electronic device and the external electronic device on a display unit.

7 . The method of claim 4 , wherein receiving the information further comprises:
detecting a second battery residual amount; generating a charging score of the external device in accordance with the second battery residual amount and predetermined values of charging factors; and transmitting the charging score to the external electronic device.

8 . The method of claim 7 , wherein the charging factor comprises a battery capacity.

9 . The method of claim 7 , wherein the charging factor is determined by a possibility of an emergency call.

10 . The method of claim 7 , wherein the charging factor further comprises location information of the second device.

11 . The method of claim 7 , wherein the charging factor further comprises a user preference.

12 . The method of claim 7 , wherein the charging factor further comprises a device usage frequency.

13 . The method of claim 1 , further comprising:
determining a charging by receiving the electric power from the external electronic device if the information associated with the second battery is greater than the first battery; determining a charging by supplying the electric power to the external device if the information associated with the first battery is greater than the secondary battery; and determining not to charge if the information associated with the first battery and the second battery is balanced.

14 . The method of claim 13 , further comprising:
generating the charging score and transmitting the charging score to the external electronic device according to a charging amount change if a charging operation is performed.

15 . The method of claim 14 , further comprising:
displaying a charging state of the first battery and the second battery with at least one of a popup displaying technique or an indicator displaying technique if the charging operation is performed.

16 . The method of claim 15 , further comprising:
comparing the information associated with the first battery with the information associated with the second battery of the external electronic device while performing the charging operation, wherein the electric power is not transferred if the information associated with the first battery and the second battery satisfy a predetermined value.

17 . The method of claim 1 , further comprising:
determining a charging by supplying the electric power to the external electronic device if the information associated with the second battery includes emergency call information, and determining a charging by receiving the electric power from the external electronic device if the information associated with the first battery includes emergency call information.

18 . The method of claim 1 , further comprising:
determining a charging by receiving the electric power from the external electronic device if the information associated with the second battery includes information of connecting the charger to an external power; and determining a charging by supplying the electric power to the external electronic device if the information associated with the first battery includes information of connecting the charger to an external power.

19 . The method of claim 1 , further comprising:
determining a charging by receiving the electric power from the external electronic device if the external electronic device is located at a lower side of the electronic device; and determining a charging by supplying the electric power to the external electronic device if the external electronic device is located at an upper side of the electronic device.

20 . The method of claim 1 , further comprising:
determining a charging by receiving the electric power from the external electronic device if the external electronic device is located at the upper side of the electronic device; and determining a charging by supplying the electric power to the external electronic device if the external electronic device is located at the lower side of the electronic device.

21 . The method of claim 1 , further comprising:
determining a number of connected devices, wherein a charging direction for the number of connected devices is determined in accordance with the charging score such that a device having the greatest charging score charges a device having the smallest charging score and a device having the second greatest charging score charges a device having the second smallest charging score.

22 . A method for operating an electronic device, the method comprising:
transmitting, by the electronic device including a first battery, information related to the first battery to an external electronic device having a second battery; and receiving a signal or an indication configured to indicate at least one of: (i) receiving an electric power from the external electronic device to the electronic device, (ii) supplying an electric power from the electronic device to the external electronic device, or (iii) not transferring an electric power between the electronic device and the external electronic device.

23 . An electronic device comprising:
a first battery; a charger configured to charge the first battery by using an external power; a wireless charger configured to perform a wireless charging between a second battery of an external electronic device and the first battery; a communication unit configured to receive information associated with the second battery from the external electronic device, wherein the external electronic device includes the second battery; and a controller configured to identify occurrence of at least one operation of (i) receiving an electric power from the external electronic device through the communication unit based on at least one of information related to the second battery or information related to the first battery, (ii) supplying an electric power to the exter
