Patent attributes
A method and apparatus for estimating a state of a battery are provided. A battery life estimation apparatus includes a time information accumulator configured to partition sensing data of a battery into sections, and to accumulate time information corresponding to the sections. The battery life estimation apparatus also includes a time information extractor configured to extract time information corresponding to a period from the accumulated time information. The battery life estimation apparatus further includes a life estimator configured to extract expected time information based on the accumulated time information, the time information corresponding to the period, and learning information, and configured to estimate an end of life (EOL) of the battery based on the expected time information.
