Method for determining a parameter of at least one accumulator of a battery

Abstract : A method for determining a parameter such as the resistance of at least one accumulator of a battery. The method includes the following steps: measuring a first voltage (U1) when the current is substantially equal to a predetermined value; conducting the plurality of voltage and current measurements (Un; In) during a current pulse; calculating a plurality of resistance values (Rn) from the first voltage and from the plurality of voltage and current measurements; determining a resistance value as the average of the calculated resistance values and an associated standard deviation; determining an absolute uncertainty on the value of the resistance as the product of the standard deviation and of a Student coefficient; if the relative uncertainty is less than or equal to a predetermined accuracy threshold, validating the resistance value (R).
