Abstract

Various embodiments of the present invention relate to an electronic device and a charging control method therefor. The electronic device may comprise: a connection terminal for performing wired communication with an external electronic device; and at least one processor functionally connected to the connection terminal, wherein the at least one processor detects connection of a charging device through the connection terminal, receives state information of at least one adjacent terminal located next to a power terminal of the connection terminal, and controls charging power to be supplied thereto through the charging device, on the basis of the received state information of the adjacent terminal. In addition, various other embodiments are possible.

First claim

What is claimed is:

1. An electronic device comprising:
a connection terminal configured to wiredly communicate with an external electronic device; and
at least one processor functionally connected with the connection terminal, wherein the at least one processor is configured to:
detect a connection of a charging device through the connection terminal;
receive state information of at least one adjacent terminal positioned next to a power terminal of the connection terminal, the state information indicates whether the at least one adjacent terminal is short-circuited with the power terminal;
in response to the state information indicating the short-circuit, transmit, to the charging device, a request for controlling a charging power of the charging device to be supplied from the charging device to the electronic device, the request causing a charging voltage of the charging power to be maintained at a designated voltage or lower, causing a charging by the charging device to stop, or transmitting a reset command to the charging device periodically;
in response to the state information indicating the short-circuit, notify a user that the charging power is restricted or stopped due to the short-circuit, and notify the user that a disconnection of the charging device;
after the charging device is disconnected, identify whether the at least one adjacent terminal is short-circuited again; and
in response to a result of the identification indicating the short-circuit again, determine that the short-circuit occurs in the connection terminal of the electronic device, and notify the user that the short-circuit has occurred in the connection terminal.

2. The electronic device of claim 1 , wherein, when the charging device supports fast charging of charging a battery with a voltage exceeding the designated voltage, the at least one processor is configured to identify the state information of the at least one adjacent terminal.

3. The electronic device of claim 1 , wherein the connection terminal has a USB Type-C standard, and the at least one adjacent terminal comprises at least one of a channel configuration terminal, a reservation terminal, a negative transmission terminal, or a negative reception terminal.

4. The electronic device of claim 3 , wherein the at least one processor is configured to:
determine whether the channel configuration terminal of the connection terminal is short-circuited by comparing a voltage of the channel configuration terminal and a reference voltage.

5. The electronic device of claim 3 , wherein the at least one processor is configured to:
apply a high signal and a low signal to the reservation terminal of the connection terminal alternately, and
determine whether the reservation terminal is short-circuited by checking an output signal of the reservation terminal.

6. The electronic device of claim 1 , wherein the at least one processor is configured to:
in response to the result of the identification does not indicating the short-circuit again, determine that the short-circuit occurs in at least one of the charging device, a cable, or a gender, and
notify the user that the short-circuit has occurred in at least one of the charging device, the cable, or the gender.

7. A charging control method of an electronic device, the method comprising:
detecting a connection of a charging device to a connection terminal which wiredly communicates with an external electronic device;
identifying state information of at least one adjacent terminal positioned next to a power terminal of the connection terminal, the state information indicates whether the at least one adjacent terminal is short-circuited with the power terminal;
in response to the state information indicating the short-circuit, transmitting, to the charging device, a request for controlling a charging power of the charging device to be supplied from the charging device to the electronic device, the request causing a charging voltage of the charging power to be maintained at a designated voltage or lower, causing a charging by the charging device to stop, or transmitting a reset command to the charging device periodically;
in response to the state information indicating the short-circuit, notifying a user that the charging power is restricted or stopped due to the short-circuit, and notifying the user that a disconnection of the charging device;
after the charging device is disconnected, identifying whether the at least one adjacent terminal is short-circuited again; and
in response to a result of the identification indicating the short-circuit again, determining that the short-circuit occurs in the connection terminal of the electronic device, and notifying the user that the short-circuit has occurred in the connection terminal.

8. The method of claim 7 , further comprising identifying whether the charging device supports fast charging of charging a battery with a voltage exceeding the designated voltage,
wherein identifying the state of the at least one adjacent terminal is performed when the charging device supports the fast charging.

9. The method of claim 7 , wherein the connection terminal has a USB Type-C standard, and the at least one adjacent terminal comprises at least one of a channel configuration terminal, a reservation terminal, a negative transmission terminal, or a negative reception terminal.

10. The method of claim 7 , further comprising:
in response to the result of the identification does not indicating the short-circuit again, determining that the short-circuit occurs in at least one of the charging device, a cable, or a gender.

11. The method of claim 10 , further comprising:
notifying the user that the short-circuit has occurred in at least one of the charging device, the cable, or the gender.

12. A non-transitory computer-readable recording medium storing at least one instructions, the at least one instructions, when being executed by at least one processor, cause the at least one processor to:
detect a connection of a charging device to a connection terminal which wiredly communicates with an external electronic device;
identify state information of at least one adjacent terminal positioned next to a power terminal of the connection terminal, the state information indicates whether the at least one adjacent terminal is short-circuited with the power terminal;
in response to the state information indicating the short-circuit, transmit, to the charging device, a request for controlling a charging power of the charging device to be supplied from the charging device, the request comprises causing a charging voltage of the charging power to be maintained at a designated voltage or lower, causing a charging by the charging device to stop, or transmitting a reset command to the charging device periodically;
in response to the state information indicating the short-circuit, notify a user that the charging power is restricted or stopped due to the short-circuit, and notify the user that a disconnection of the charging device;
after the charging device is disconnected, identify whether the at least one adjacent terminal is short-circuited again; and
