Abstract
A method for estimating the aging of a battery of a motor vehicle with a combustion engine, the vehicle including an electric starter, a temperature sensor for the temperature of the coolant, a speed sensor for the speed of the combustion engine and a computer for managing the drive system of the vehicle. The method includes, each time the combustion engine is started, the steps of the computer determining the value of the speed of the combustion engine and the value of the temperature, if the determined value of the speed is higher than a speed threshold, incrementing a first counter, if the determined value of the speed is lower than the speed threshold, incrementing a second counter, detecting the aging of the battery when the value of the second counter is higher than a predetermined alert threshold.
