BATTERY CAPACITY ESTIMATION APPARATUS AND METHOD

Provided is a battery capacity estimation apparatus including a voltage measuring unit measuring a voltage of a battery cell, a filtering unit determining voltage data as first data when a logging pattern of the voltage data of the battery cell deviates from a preset reference range, a statistical analyzing unit determining second data through statistical analysis on the voltage data of the battery cell, and a capacity estimating unit estimating a capacity by applying data, classified by the filtering unit or the statistical analyzing unit for a battery cell that is a measurement target, to capacity estimation models generated separately for the first data and the second data.
