Abstract

A password setting device includes a selection button and a plurality of light-emitting elements. The selection button determines a state of charge of a battery pack and is also used to enter various types of information including symbols of a password. The light-emitting elements to emit light depending on the state of charge of the battery pack in a first mode. At least some of the light-emitting elements correspond to symbols of a password in at least a second mode. The password is to be set or input based on the light-emitting elements that emit light at a time when the selection button is activated in at least the second mode.

Claims

1. A password setting device, comprising:

a selection button to determine a state of charge of a battery pack; and

a plurality of light-emitting elements to emit light depending on the state of charge of the battery pack in a first mode, wherein at least some of the light-emitting elements correspond to symbols of a password in at least a second mode, and wherein the password is to be set or input based on the light-emitting elements that emit light at a time when the selection button is activated in at least the second mode.

2. The device as claimed in claim 1, further comprising

a driving controller to enter into one of a plurality of modes based on a manipulation time of the selection button, the plurality of modes including:

the first mode including a state of charge display mode to display the state of charge of the battery pack,

the second mode including a password setting mode to set the password,

a third mode including a password input mode to input the password, and

a fourth mode including a lock mode to set a motor in a locked state.

3. The device as claimed in claim 2, wherein the driving controller is to:

detect the state of charge of the battery pack, and

enable at least one of the light-emitting elements to emit light depending on the detected state of charge in the first mode.

4. The device as claimed in claim 2, wherein the driving controller is to:

sequentially enable the light-emitting elements to emit light in the password setting mode, and

set symbols of the password corresponding to the light-emitting elements that emit light.

5. The device as claimed in claim 4, wherein the driving controller is to:

enable the light-emitting elements to sequentially emit light in the password input mode,

recognize symbols for the light-emitting elements that emit light,

compare the recognized symbols with preset symbols, and

selectively unlock a locked state of a host device of the battery pack.

6. The device as claimed in claim 1, wherein the symbols of the password are one or more of numbers, letters, or characters.

7. A method for setting a password, the method comprising:

enabling a plurality of light-emitting elements to emit light; and

setting or inputting symbols of a password corresponding to the light-emitting elements when a selection button is manipulated, wherein the password controls access to a host device powered by a battery pack.

8. The method as claimed in claim 7, wherein setting or inputting symbols of the password includes:

respectively matching the light-emitting elements to different symbols; and

storing the set or input symbols matched to the light-emitting elements which emit light based on activation of the selection button.

9. The method as claimed in claim 7, further comprising:

entering into one of a plurality of modes based on a manipulation time of the selection button, wherein the plurality of modes includes;

a state of charge display mode to display a charge state of the battery pack,

a password setting mode to set the password,

a password input mode to input the password, and

a lock mode to set the host device in a locked state.

10. The method as claimed in claim 9, wherein entering into the state of charge display mode includes:

detecting the state of charge of the battery pack, and

enabling at least one of the light-emitting elements to emit light depending on the detected state of charge.

11. The method as claimed in claim 9, wherein entering into the password input mode includes:

comparing a preset password with the set or input password; and

unlocking the locked state of a motor when the set or input password matches the preset password.

12. The method as claimed in claim 7, wherein the symbols of the password are one or more of numbers, letters, or characters.

13. An apparatus, comprising:

an input to receive signals from a control panel; and

a controller to receive a password corresponding to the signals received from the control panel and to compare the received password to a preset password, wherein the controller is to lock a motor when the received password does not match the preset password.

14. The apparatus as claimed in claim 13, wherein:

the password includes a number of symbols; and

the controller is to identify the symbols based on light emitting elements that emit light.

15. The apparatus as claimed in claim 14, wherein the controller is to identify the symbols based on a position of the light emitting elements and logical values of signals received from the light emitters.

16. The apparatus as claimed in claim 15, wherein light emitting elements that do not emit light have a same logical value and correspond to symbols that are not included in the password.

17. The apparatus as claimed in claim 16, wherein the symbols include one or more of numbers, letters, or characters.

18. The apparatus as claimed in claim 13, wherein the input is included in the controller.

19. The apparatus as claimed in claim 13, wherein the controller is to generate signals for activating a combination of the light emitting elements based on a state of charge of a battery pack of the electric vehicle.

20. The apparatus as claimed in claim 13, wherein the controller controls a mode of the control panel based on a selection signal received from the control panel.
