Abstract
A method and apparatus for predicting a capacity fade rate of a battery are provided. The method includes collecting capacity degradation data of a battery based on a current and a state of charge (SOC) for a predefined number of cycles, generating a capacity fade model based on the capacity degradation data, and estimating a capacity fade rate of the battery using the capacity fade model.
