1. A method of rapidly charging a battery, the method comprising:

  • detecting a temperature, by a temperature detection unit;

    detecting a voltage of a secondary battery, by a voltage detection unit;

    determining whether the voltage of the secondary battery detected through the battery detection unit is lower than a first voltage, by a control unit;

    if the voltage of the secondary battery is lower than the first voltage, rapidly primarily charging the secondary battery by applying a temperature compensation factor to a first constant current, by the control unit;

    if the voltage of the secondary battery is not lower than the first voltage, determining whether the voltage of the secondary battery is lower than a second voltage that is higher than the first voltage, by the control unit;

    if the voltage of the secondary battery is lower than the second voltage, charging the secondary battery by applying the temperature compensation factor to a second constant current, by the control unit;

    if the voltage of the secondary battery is not lower than the second voltage, determining whether the voltage of the secondary battery is lower than a third voltage, by the control unit;

    if the voltage of the secondary battery is lower than the third voltage, charging the secondary battery by applying the temperature compensation factor to a third constant current, by the control unit; and

    if the voltage of the secondary voltage is not lower than the third voltage, terminating the charging operation.
