A battery control module for a battery system comprises a voltage measuring module that measures battery and a current measuring module that measures battery current. A state of charge (SOC) module communicates with the current and voltage measuring modules and estimates SOC at least one of when an accumulated charge swing during charge is greater than or equal to an accumulated discharge swing during a prior discharge and a negative of a charge current is within a predetermined window of a negative of a retained discharge current during the prior discharge and/or when an accumulated discharge swing during discharge is greater than or equal to an accumulated charge swing during a prior charge and a negative of a discharge current is within a predetermined window of a negative of a retained charge current during the prior charge.
