METHOD AND SYSTEM FOR PREDICTING BATTERY CAPACITY DEGRADATION FOR ELECTRIC VEHICLE

A method and a system for predicting a battery capacity degradation for an electric vehicle having a battery are provided. The method comprises extracting and pre-processing a raw dataset comprising a plurality of battery loss indicators and a plurality of battery loss values each corresponding to a plurality of time steps to obtain a pre-processed dataset. The method further comprises selecting a loss indicator subset from the pre-processed dataset at a first time step and a second time step based on a smart feature selection (SFS) algorithm. The method further comprises training a machine learning model with each battery loss indicator at the first and second time steps and the battery loss value at the first time step. The method further comprises determining the battery loss value at the second time step with the machine learning model to predict the battery capacity degradation.
