Abstract

The present invention relates to a system and method for training a model for predicting a capacity of a battery. The method comprises the steps of: - charging or discharging a training set comprising one or more batterie; - periodically measuring, during charging or discharging, the voltages and currents of the training set; - calculating an Incremental Capacity Differentiation (ICD) curve for the batteries of the training set; - calculating the capacities of the batteries of the training set; - constructing a model that takes an ICD curve as an input and returns a predicted capacity as an output; - training the model with the ICD curves and the capacities of the training set. In addition, the present invention relates to a system and method for predicting a capacity of a battery, using the trained model.
