A method assesses a state of charge of a battery including a plurality of electrochemical cells connected in series that each have a state of charge held between a minimum allowable state of charge value and a maximum allowable state of charge value. The method includes determining, at a given moment, the minimum cell voltage and the maximum cell voltage from the voltages at terminals of the cells, calculating a minimum state of charge of the cell having the minimum cell voltage and a maximum state of charge of the cell having the maximum cell voltage, and adjusting the minimum allowable state of charge value and the maximum allowable state of charge value of each cell depending on at least one physical quantity representative of a state of health of the cell and/or depending on a temperature of the battery. |
