Zusammenfassung:	A method and apparatus for controlling battery state of charge (SOC) in a hybrid electric vehicle are provided to enable the efficient use of energy, the maximization of energy recovery, and the improvement of fuel efficiency and operability without the improvement of capacity and performance of electrical equipment or a main battery in a hybrid electric vehicle. The apparatus includes a collecting device that collects information regarding the slope or the road type and information regarding the vehicle speed. A controller determines charge and discharge modes based on the driving information and determines a charging upper and lower limit SOC based on the road slope or road type information a road section on which the vehicle is traveling and the vehicle speed information in the road section. A charge or discharge command is output based on the charging upper limit SOC and the charging lower limit SOC.
