Abstract
A battery diagnosing apparatus may include a voltage measuring circuit for generating a voltage signal representing a battery voltage across both ends of each of batteries; a database for storing abnormal patterns, a plurality of reference time series, and a predetermined corresponding relationship between the abnormal patterns and the plurality of reference time series; and a control unit for generating a plurality of input time series representing a change history of the battery voltage of each battery, based on the voltage signal. The control unit may extract an abnormal input time series representing an abnormal voltage behavior among the plurality of input time series by comparing the plurality of input time series with each other. The control unit may identify an abnormal pattern of the abnormal input time series among the abnormal patterns by comparing the abnormal input time series with the plurality of reference time series one by one.
