Apparatus for predicting battery lifetime and method thereof

Abstract

The present invention relates to an apparatus for predicting battery lifetime that may predict battery time more accurately by removing errors due to a characteristic of recovering temporary capacity happening intermittently from charge/discharge test data of a battery and a method thereof. The apparatus for predicting battery lifetime in accordance with the present invention comprises: a capacity recovery section-determining unit for determining a temporary capacity recovery section by analyzing charge/discharge test data of a battery; a trend analysis unit for creating alternative data based on test data before and after the temporary capacity recovery section determined by the capacity recovery section-determining unit, and analyzing trend of the test data by reflecting the alternative data; and a lifetime predicting unit for predicting lifetime of the battery based on data outputted from the trend analysis unit.
