1. A battery life estimation apparatus comprising:
- a stress pattern extractor configured to use at least one processing device to extract a stress pattern from sensing data acquired for a battery, the stress pattern representing changes in states of the battery based on stresses applied to the battery and characterized by categorizing different stresses represented in the sensing data; and
a life estimator configured to use at least one processing device to estimate a life of the battery based on the characterized stress pattern.

Abstract
A method and apparatus for estimating a state of a battery are provided. A battery life estimation apparatus may acquire sensing data of a battery, may extract a stress pattern from the sensing data that represents changes in states of the battery based on stress applied to the battery, and may estimate a life of the battery based on the stress pattern.
