Abstract
A method for estimating the charge of a battery comprises: acquiring at least one time series of measurements of voltage across the terminals of the battery, and at least one other time series of measurements of another physical parameter of the battery or of its environment; determining an operating regime of the battery; choosing a regression model from among a predefined set of such models; and estimating the charge of the battery by applying the regression model to the time series of voltage measurements and to at least one other time series of measurements. A device for estimating the charge of a battery and a device for training regression models of the charge of a battery, adapted for the implementation of the method are provided. A system for estimating the charge of a battery comprising a device for estimating the charge and a device for training regression models is provided.
