Abstract

A battery pack and a battery driving apparatus are disclosed. In one aspect, the battery pack includes a battery comprising at least one battery cell, and a terminal unit configured to be connected to an external apparatus. The battery pack further includes a controller configured to control the battery, be deactivated in a shut down mode, and wake up from the shut-down mode when a voltage is applied to the terminal unit and a wake-up switch configured to electrically connect the battery and the terminal unit.

Claims

1. A battery pack, comprising:

a battery comprising at least one battery cell;

a terminal unit configured to be connected to an external apparatus;

a controller configured to control the battery, be deactivated in a shut down mode, and wake up from the shut-down mode when a voltage is applied to the terminal unit; and

a wake-up switch configured to electrically connect the battery and the terminal unit.

2. The battery pack of claim 1, wherein the controller comprises a wake-up terminal connected to the terminal unit.

3. The battery pack of claim 2, wherein the wake-up terminal is configured to receive the same voltage as the terminal unit when the wake-up switch is turned on.

4. The battery pack of claim 1, further comprising a sensor configured to detect an external signal and turn on the wake-up switch in response to the external signal.

5. The battery pack of claim 4, wherein the external signal is indicative of at least one of a magnetic field, light and pressure.

6. The battery pack of claim 1, further comprising a microcomputer configured to turn off the wake-up switch when the controller is not in the shut-down mode.

7. The battery pack of claim 1, further comprising a charging switch and a discharging switch connected in series between the battery and the terminal unit.

8. The battery pack of claim 1, further comprising a housing configured to protect the battery and the controller, wherein the wake-up switch is located outside the housing.

9. The battery pack of claim 1, wherein the wake-up switch comprises a transistor or a relay configured to be turned on based on the voltage.

10. The battery pack of claim 1, wherein the wake-up switch comprises a toggle switch configured to be manually turned on or off.

11. The battery pack of claim 1, wherein each of the battery and terminal unit comprises a positive terminal, and wherein the wake-up switch is configured to electrically connect the positive terminal of the battery and the positive terminal of the terminal unit when the wake-up switch is turned on.

12. A battery driving apparatus, comprising:

a body that comprises a signal emitter configured to emit a wake-up signal;

a battery pack mounted on the body; and

an electric apparatus configured to be driven by power of the battery pack,

wherein the battery pack comprises;

a battery comprising at least one battery cell;

a terminal unit configured to be connected to an external apparatus;

a controller configured to control the battery, be deactivated in a shut down mode, and wake up from the shut-down mode when a voltage is applied to the terminal unit; and

a wake-up switch configured to electrically connect the battery and the terminal unit.

13. The battery driving apparatus of claim 12, wherein the controller comprises a wake-up terminal connected to the terminal unit.

14. The battery driving apparatus of claim 12, wherein the battery pack further comprises a sensor configured to detect the wake-up signal and turn on the wake-up switch in response to the wake-up signal.

15. The battery driving apparatus of claim 12, wherein the sensor comprises at least one of a magnetic sensor, an optical sensor and a pressure sensor.

16. The battery driving apparatus of claim 12, wherein the battery pack further comprises a microcomputer configured to turn off the wake-up switch when the controller is not in the shut-down mode.

17. The battery driving apparatus of claim 12, wherein the battery pack further comprises a charging switch and a discharging switch connected in series between the battery and the terminal unit.

18. The battery driving apparatus of claim 12, wherein the battery pack further comprises a housing configured to protect the battery and the controller, and wherein the wake-up switch is located outside the housing.
