One embodiment of the present invention is to classify the state of charge/discharge according to a polarization voltage and to estimate a state of charge of a battery in the each classified state of charge/discharge. Therefore, the complexity of a system and a speed of calculation are improved by differentiating criteria for estimating the state of charge/discharge of a battery.
