A method for estimating a state of charge (SOC) value of a battery may include determining, by a controller, whether an entry condition for estimating the SOC value of the battery is satisfied based on state data of the battery; generating, by the controller, an initial SOC value of the battery using an internal resistance value of the battery when the state data satisfies the entry condition; generating, by the controller, a first storage capacity of the battery to generate using the initial SOC value; generating, by the controller, a second storage capacity of the battery using the first storage capacity and a charging efficiency of the battery; and estimating, by the controller, the SOC value of the battery using the second storage capacity.
