1. A method for estimating the state of health of a battery of an electric or hybrid vehicle in conditions of use, comprising the following steps:

  • a) during the operation of said battery, acquiring a time series of measurements of speed or of acceleration of said vehicle and, simultaneously, at least one time series of measurements of a quantity chosen from;

    a current or a power delivered by said battery, and a voltage at its terminals;

    b) extracting segments of said time series corresponding to speed or acceleration patterns that satisfy at least one predefined condition; and

    c) determining estimations of the state of health of said battery by application of at least one continuous estimation or classification model to said segments of said time series.
