Abstract
The invention relates to a method for predicting the remaining life of an electrochemical cell having a SOC-OCV characteristic with a planar portion extending between two limits, said method comprising the steps of obtaining voltage and current measurements from the electrochemical cell during a discharge, detecting a limit; calculating the values at the voltage limit detected and the amount of charge lost; predicting the resistance and capacitance of the electrochemical cell by applying respective predictive functions obtained by a learning technique to the voltage and the amount of charge lost at the limit detected; and predicting the remaining life of the electrochemical cell from the predicted resistance and predicted capacitance.
