Abstract
A method for estimating a state of charge of a battery including plural cells connected in series, including: determination, at a given time, of a minimum cell voltage and of a maximum cell voltage from among the cell voltages, and calculation of a physical quantity analytically depending on the minimum and maximum cell voltages according to an equation including weighting elements ensuring the weight associated with the maximum cell voltage increases when the state of charge of the associated cell increases, and the weight associated with the minimum cell voltage increases when the state of charge of the associated cell decreases.
