Abstract
An estimation method for estimating a cell's state-of-charge includes obtaining a capacitance prediction for a cell based at least in part on a preceding capacitance thereof and correcting that prediction by acquiring measurements of a physical quantity that depends on a summation of currents passing through the cell. The correction is based at least in part on a difference between the measurement of the physical quantity and a prediction for that quantity.
