Abstract
The invention relates to a method, implemented in a management system of an electric battery of a vehicle, for estimating the resistive state of health of at least one electrical energy storage element, the method comprising the next steps: —determining () at least one operating range for which the direct current resistance of the element changes linearly with respect to the state of charge of the element and to temperature; —measuring () the variation in the strength and the voltage of an electric current generated by the element during a running phase of the vehicle; —calculating (), based on the measured values of variation in strength and voltage, at least one direct current resistance value of the element; and —calculating () at least one value of the resistive state of health of the element based on the calculated direct current resistance value.
