Original Abstract Submitted
An apparatus for diagnosing a battery according to one aspect of the present disclosure may include a measuring unit configured to measure a voltage value of the battery at each predetermined cycle during a battery charging process; and a processor configured to calculate a resistance value of the battery based on the measured voltage value of the battery, determine a resistance change pattern by comparing the calculated plurality of resistance values with a preset criterion profile, and determine the state of the battery based on the determined resistance change pattern.
