Abstract
A battery diagnosing apparatus includes a measuring unit configured to measure a current, a voltage and an OCV of a battery, a resistance estimating unit configured to estimate a resistance of the battery based on the current and the voltage measured by the measuring unit, and a control unit configured to calculate a voltage deviation for a criterion OCV set to correspond to the battery and the OCV measured by the measuring unit, calculate a resistance deviation for a criterion resistance set to correspond to the battery and the resistance estimated by the resistance estimating unit, and diagnose a state of the battery based on a voltage increase/decrease pattern for the voltage deviation and a resistance increase/decrease pattern for the resistance deviation.
