Abstract An apparatus for estimating battery state of charge may include a sensor configured to sense a voltage value and a current value of a battery, an internal resistance calculator configured to calculate an internal resistance using the voltage value and the current value, a noise remover configured to determine an output accumulation method or an open circuit using method using an open circuit voltage to remove a noise due to the internal resistance, an output accumulator configured to accumulate and calculate a residual capacity of the battery depending on the output accumulation method, a compensated state of charge calculator configured to calculate a compensated state of charge of the battery using a preset lookup table depending on the open circuit using method, and a battery state of charge estimator configured to calculate an estimated state of charge of the battery using the residual capacity or the compensated state of charge.
