Abstract
A method for predicting an acceleration of the degradation in capacity of an electrochemical device. The method includes obtaining point measurement data from a function linking a voltage across the terminals of the electrochemical device to a state of charge of the electrochemical device, and a measurement of the capacity of the electrochemical device, calculating the derivative of the function and identifying a peak in the variation of the derivative, due to an inflection in the variation of the function and characterizing a quantity representative of an anode capacity of the electrochemical device, estimating a width of the peak and comparing a combination of the peak width and the quantity representative of the anode capacity, to the measurement of the capacity of the electrochemical device, and if the combination is less than the capacity of the electrochemical device, predicting an acceleration of the degradation in capacity of the electrochemical device.
