Abstract: A method and an apparatus for charging a battery by using a target SOC(State Of Charge) in a hybrid electric vehicle are provided to drive the vehicle in an expected driving condition by managing the current SOC of the battery considering the expected driving condition. A required power operation unit(30) calculates torque from an acceleration position value outputted from an acceleration position sensor(10) and outputs required power by multiplying the torque by vehicle speed outputted from a vehicle speed sensor(20). A target SOC calculating unit(40) receives the required power from the required power operation unit and the current SOC of the battery from a battery managing system and calculates a target SOC of the battery by using the required power, the current SOC of the battery, a reference power value, and a reference energy value. A charge control unit changes charge control operation of the battery according to the difference between the target SOC and the current SOC of the battery.
