The invention relates to a method for estimating the state of charge of a cell comprising the following steps: - preventing (164) the full execution of an algorithm for estimating the capacitance Cn,k3 of the cell for as long as the value of a parameter does not exceed a predetermined threshold, wherein said parameter is chosen from the group consisting of the measured value yk of a voltage across the terminals of the cell, the estimated state of charge SOCk of the cell and an amount Qk of current discharged by the cell between a time k and a previous time, then - initiating (164) full execution of the algorithm for estimating the capacitance Cn,k3 when said parameter falls below the predetermined threshold if the parameter is the measured value yk or the estimated state of charge SOCk, or rises above the predetermined threshold if said parameter is the discharged amount Qk of current. |
