Abstract

A charge device for controlling an abnormal charge request is provided. The charge device includes a controller that interrupts a charge path, when power is applied and that determines whether a charge request is an abnormal charge request through a detour charge path and that controls to maintain interruption of the charge path, if the charge request is an abnormal charge request. The controller may be further configured to interrupt the detour charge path, in response to determining that the charge request is a normal charge request; connect the charge path; and supply a charge current to the charge path.

Claims

1. A charge device, comprising:

a controller configured to;

interrupt a charge path, when power is applied;

determine whether a charge request is an abnormal charge request through a detour charge path; and

control to maintain interruption of the charge path, in response to determining that the charge request is an abnormal charge request.

2. The charge device of claim 1, further comprising a Field Effect Transistor (FET) element to interrupt or connect the charge path or the detour charge path.

3. The charge device of claim 1, further comprising a Low Drop Out (LDO) element configured to lower and supply a voltage through the detour charge path.

4. The charge device of claim 1, wherein the controller is configured to control to:

interrupt the detour charge path, in response to determining that the charge request is a normal charge request;

connect the charge path; and

supply a charge current to the charge path.

5. The charge device of claim 1, wherein the controller is configured to compare a voltage measured through the detour charge path to a reference voltage;

and determine whether the charge request is an abnormal charge request.

6. The charge device of claim 1, wherein the controller is configured to compare a current measured through the detour charge path to a reference current and determine whether the charge request is an abnormal charge request.

7. The charge device of claim 1, further comprising at least one of a display, an indicating lamp, a speaker, and a vibration generator configured to provide a notification of the abnormal charge request.

8. A method of controlling charge in a charge device, the method comprising:

interrupting a charge path, when power is applied;

determining whether a charge request is an abnormal charge request through a detour charge path; and

maintaining, in response to determining that the charge request is an abnormal charge request, interruption of the charge path.

9. The method of claim 8, further comprising interrupting or connecting the charge path or the detour charge path using a switch.

10. The method of claim 8, wherein determining whether the charge request is an abnormal charge request comprises comparing a voltage measured through the detour charge path to a reference voltage;

and determining whether the charge request is an abnormal charge request.

11. The method of claim 8, wherein determining whether the charge request is an abnormal charge request comprises comparing a current measured through the detour charge path to a reference current;

and determining whether the charge request is an abnormal charge request.

12. The method of claim 8, further comprising notifying, in response to determining that the charge request is an abnormal charge request, the abnormal charge request through at least one of a display, an indicating lamp, a speaker, and a vibration generator.

13. The method of claim 8, further comprising interrupting, in response to determining that the charge request is a normal charge request, the detour charge path, connecting the charge path, and supplying a charge current to the charge path.

14. The method of claim 8, further comprising lowering and supplying a voltage through the detour charge path using a Low Drop Out (LDO) element.

15. A non-transitory computer-readable medium comprising instructions, that when executed by at least one processor, cause a charge device to:

interrupt a charge path, when power is applied;

determine whether a charge request is an abnormal charge request through a detour charge path; and

maintain, in response to determining that the charge request is an abnormal charge request, interruption of the charge path.

16. The computer-readable medium of claim 15, further comprising instructions, that when executed by at least one processor, cause the charge device to interrupt or connect the charge path or the detour charge path using a switch.

17. The computer-readable medium of claim 15, wherein the instructions for determining whether the charge request is an abnormal charge request comprise instructions, that when executed by at least one processor, cause the charge device to compare a voltage measured through the detour charge path to a reference voltage;

and determine whether the charge request is an abnormal charge request.

18. The computer-readable medium of claim 15, wherein the instructions for determining whether the charge request is an abnormal charge request comprise instructions, that when executed by at least one processor, cause the charge device to compare a current measured through the detour charge path to a reference current;

and determine whether the charge request is an abnormal charge request.

19. The computer-readable medium of claim 15, further comprising instructions, that when executed by at least one processor, cause the charge device to notify, in response to determining that the charge request is an abnormal charge request, the abnormal charge request through at least one of a display, an indicating lamp, a speaker, and a vibration generator.

20. The computer-readable medium of claim 15, further comprising instructions, that when executed by at least one processor, cause the charge device to interrupt, in response to determining that the charge request is a normal charge request, the detour charge path, connect the charge path, and supply a charge current to the charge path.
