Abstract

Methods and systems for predicting a cell capacity associated with a cell of an electrochemical cell system are provided. In one exemplary embodiment, the method determines a first predicate cell capacity of the cell of the electrochemical cell system. The method further includes measuring a voltage of the cell to obtain a measured voltage. The method further includes determining a corrected predicted cell capacity of the cell based on the first predicted cell capacity, the measured voltage, and a gain factor.
