Abstract: A method and apparatus for predicting a state of charge (SoC) of a battery includes estimating an open circuit voltage of the battery based on an open current voltage model, where the open current voltage model is defined by internal parameters that are derived from a battery voltage of the battery, a load current of the battery for a load, or a first SoC of the battery, or any combination thereof; and predicting a second SoC based on the estimated open current voltage.
