A method for estimating the state of health of a battery of an electric or hybrid vehicle in conditions of use, comprises the following steps: a) during the operation of the battery, acquiring a time series of measurements of speed or of acceleration of the vehicle and, simultaneously, at least one time series of measurements of a quantity chosen from: a current or a power delivered by the battery, and a voltage at its terminals; b) extracting segments of the 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 the battery by application of at least one continuous estimation or classification model to the segments of the time series. A device and system for implementing such a method and a method for constructing a continuous estimation or classification model are provided.
