The method includes obtaining an open circuit voltage (OCV) of the battery in an equilibrium state, obtaining a plurality of closed circuit voltages (CCVs) over time while charging or discharging the battery by using a constant current for 1 second or less, and determining an internal resistance of the battery by using the OCV and the plurality of CCVs.",
