Device and Method for Predicting Defective Rate of Battery

Abstract

Disclosed is an apparatus for predicting a failure rate, the apparatus comprising: an aging simulator configured to generate a plurality of capacity fades by simulating a life analysis on a plurality of extended driving profiles generated by combining at least two driving profiles extracted from original data, wherein a plurality of climate conditions are applied to the life analysis; and part per million (PPM) simulator configured to generate a plurality of probability weights based on a plurality of extended weights corresponding to the plurality of extended driving profiles and weights corresponding to the plurality of climate conditions, and calculate a PPM value based on the plurality of capacity fades and the plurality of probability weights.
