Abstract

A charging device for a vehicle includes: a charge port connected to a charge cable and accessible from the outside of the vehicle; a locking device locking the charge cable to the charge port; a battery configured to be charged by electric power supplied from the charge cable; a button including an icon that is turned on according to a lock setting state and accessible from the outside of the vehicle; and a processor configured to change a lock setting state of the charge cable and the charge port according to a user input received through the button, turn on or turn off the icon included in the button according to the lock setting state, and control locking of the locking device according to the lock setting state.

Claims

1. A charging device for a vehicle, the charging device comprising:

a charge port connected to a charge cable and accessible from the outside of the vehicle;

a locking device locking the charge cable to the charge port;

a battery configured to be charged by electric power supplied from the charge cable;

a button including an icon that is turned on according to a lock setting state and accessible from the outside of the vehicle; and

a processor configured to change a lock setting state of the charge cable and the charge port according to a user input received through the button, turn on or turn off the icon included in the button according to the lock setting state, and control locking of the locking device according to the lock setting state,

wherein the icon that is turned on in the button is changed according to the lock setting state.

2. The charging device according to claim 1, wherein the lock setting state includes a lock releasing state in which locking has not been set, a first lock state in which locking is set and unset when charging is completed, and a second lock state in which locking is set and maintained after charging is completed.

3. The charging device according to claim 2, wherein the processor sets the lock setting state to the first lock state when the user input is received through the button in the lock releasing state, the processor sets the lock setting state to the second lock state when the user input is received through the button in the first lock state, and the processor sets the lock setting state to the lock releasing state when the user input is received through the button in the second lock state.

4. The charging device according to claim 1, wherein the button includes a first icon indicating whether locking is available to be set, a second icon indicating whether locking has been set, a third icon indicating a first lock state, and a fourth icon indicating a second lock state.

5. The charging device according to claim 4, wherein the processor changes the lock setting state when a user input is received through the button and the first icon is on, and does not change the lock setting state when a user input is received through the button and the first icon is off.

6. The charging device according to claim 4, wherein the processor turns off the first icon when a designated user input is received through the button, or when a designated period of time has elapsed after the first icon was turned on.

7. The charging device according to claim 4, wherein

the processor turns on the second icon and the third icon when a user input is received through the button with the first icon turned on,

turns off the third icon and turns on the fourth icon when a user input is received through the button with the first icon, the second icon, and the third icon turned on, and

turns off the second icon and the fourth icon when a user input is received through the button with the first icon, the second icon, and the fourth icon turned on.

8. The charging device according to claim 1, wherein the button includes at least one icon indicating a charge state of the battery, and the processor changes at least one of a number and a color of turned-on icons according to the charge state of the battery.

9. The charging device according to claim 1, further comprising a charge cover configured to be opened and closed and to protect the charge port,

wherein the button is positioned within the charge cover.

10. A method for controlling a charging device for a vehicle, the method comprising steps of:

connecting a charge cable to a charge port accessible from the outside of the vehicle;

receiving a user input through a button accessible from the outside of the vehicle;

changing a lock setting state of the charge cable and the charge port according to the user input;

turning on or turning off an icon included in the button according to the lock setting state; and

controlling locking of a locking device locking the charge cable to the charge port according to the lock setting state,

wherein the icon that is turned on in the button is changed according to the lock setting state.

11. The method according to claim 10, wherein the lock setting state includes a lock releasing state in which locking has not been set, a first lock state in which locking is set and unset when charging is completed, and a second lock state in which locking is set and maintained after charging is completed.

12. The method according to claim 11, wherein the step of changing the lock setting state includes steps of:

setting the lock setting state to the first lock state when the user input is received through the button in the lock releasing state;

setting the lock setting state to the second lock state when the user input is received through the button in the first lock state; and

setting the lock setting state to the lock releasing state when the user input is received through the button in the second lock state.

13. The method according to claim 10, wherein the button includes a first icon indicating whether locking is available to be set, a second icon indicating whether locking has been set, a third icon indicating a first lock state, and a fourth icon indicating a second lock state.

14. The method according to claim 13, wherein the step of changing the lock setting state includes steps of:

changing the lock setting state when the user input regarding the button is received with the first icon turned on; and

not changing the lock setting state when the user input is received through the button with the first icon turned off.

15. The method according to claim 13, wherein the step of turning on or turning off the icon included in the button includes:

turning off the first icon when a designated user input is received through the button, or when a designated period of time has elapsed after the first icon was turned on.

16. The method according to claim 14, wherein the step of turning on or turning off of the icon included in the button includes steps of:

turning on the second icon and the third icon when a user input regarding the button is received with the first icon turned on,

turning off the third icon and turning on the fourth icon when a user input regarding the button is received with the first icon, the second icon, and the third icon turned on, and

turning off the second icon and the fourth icon when a user input regarding the button is received with the first icon, the second icon, and the fourth icon turned on.

17. The method according to claim 10, wherein the button includes at least one icon indicating a charge state of a battery, and

the method further comprises a step of:

changing at least one of a number and a color of turned-on icons according to the charge state of the battery.

18. The method according to claim 10, wherein the button is positioned within a charge cover configured to be opened and closed and protect the charge port.
