Battery Diagnosis Apparatus And Battery Diagnosis Method

Abstract: Provided are a battery diagnosis apparatus and a battery diagnosis method. The battery diagnosis apparatus according to the present invention comprises: a data acquisition unit for acquiring a first target full cell profile indicating a correspondence relationship between a capacity factor and a voltage of a target cell while a first electrical stimulus is applied to the target cell; and a control circuit for generating an estimated full cell profile on the basis of the first target full cell profile and an overvoltage profile. The control circuit determines a first performance factor group as a primary estimation result for the charging and discharging performance of the target cell by applying cell diagnosis logic to the estimated full cell profile. If the diagnostic performance of a factor correction model is evaluated as having satisfied a predetermined condition, the control circuit applies the factor correction model to the first performance factor group so as to determine a second performance factor group as a secondary estimation result for the charging and discharging performance of the target cell.
