An apparatus for charging a battery of an electric device that has a motor by not charging the battery before the electric device is used and a method of charging a battery of an electric device that has a motor by using the apparatus. The apparatus includes a load, a motor for driving the load, a battery that provides a power supply to the motor, a generator that converts a kinetic energy that is generated by the motor to an electric energy, and a control unit that senses an amount of the load of the load and, if the amount of the load is less than a reference value, charges the battery by a first charging mode by using the electric energy output from the generator.

1. An apparatus for charging a battery, the apparatus comprising: a load;a motor for driving the load;a battery that provides a power supply to the motor;a generator, separate from the motor, that converts a kinetic energy that is generated by the motor to an electric energy; anda control unit that senses an amount of the load and, if the amount of the load is less than a reference value, charges the battery by a first charging mode, wherein the first charging mode is used to charge the battery by using the electric energy that is output from the generator. 2. The apparatus of claim 1, further comprising an external power supply providing unit that provides power supply to the apparatus, wherein the control unit controls the battery to be charged using the power supply provided by the external power supply providing unit. 3. The apparatus of claim 2, further comprising a charger that is connected to the external power supply providing unit to charge the battery, wherein the control unit controls the battery to be charged using a charging power supply provided by the charger. 4. The apparatus of claim 1, wherein the control unit controls the battery to be charged by a second charging mode by using dump power. 5. The apparatus of claim 4, wherein the dump power is generated when the motor is turned off from an on-state or turned on from an off-state. 6. The apparatus of claim 1, further comprising a regulator that maintains a charging voltage of the battery constant. 7. The apparatus of claim 1, further comprising a backflow prevention unit that prevents a backflow from the battery. 8. The apparatus of claim 1, wherein the control unit controls the battery to be charged by a third charging mode by user's input. 9. The apparatus of claim 8, further comprising a user button for the third charging mode. 10. The apparatus of claim 9, wherein, when the user button is pushed, the battery is charged using the electric energy output from the generator. 11. The apparatus of claim 9, wherein, when the user button is pushed, the battery is charged using the power supply provided by the external power supply providing unit. 12. The apparatus of claim 9, wherein, when the user button is pushed, the battery is charged using the charging power supply provided by a charger. 13. A method of charging a battery, the method is used to operate an electric device that comprises a motor for driving a load and a battery for providing a power supply to the motor, the method comprising: sensing an amount of the load; andcharging the battery by a first charging mode when the sensed amount of the load is less than a reference value, wherein the first charging mode converts kinetic energy, generated by the motor, to an electric energy, by a separate generator, to charge the battery. 14. The method of claim 13, further comprising charging the battery by a second charging mode by using dump power. 15. The method of claim 14, wherein the dump power is generated when the motor is turned off from an on-state or turned on from an off-state. 16. The method of claim 13, further comprising charging the battery by a third charging mode by user's input.
