Abstract: A storage system configured for use with an energy management system is provided and includes an AC rechargeable battery and a power converter operably coupled to the AC rechargeable battery and configured to calculate an estimate of state-of-charge of the AC rechargeable battery based on at least one of DC impedance of the AC rechargeable battery or AC impedance of the AC rechargeable battery that are measured in real time operation is used to calculate resistance and capacitance values for an equivalent circuit model that in conjunction with previously measured voltage and current are input to an extended kalman filter (EKF). Time consuming testing of the equivalent circuit model in advance is therefore eliminated.
