Abstract
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.
Claims16
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;
- and
- a 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.
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;
- and
- charging 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.
