Abstract
A battery management apparatus and method performs appropriate control to increase the lifespan of a battery cell by judging whether degradation of the battery cell is accelerated. Since both the voltage change pattern and the differential capacity change pattern between the plurality of peaks included in the plurality of differential profiles are considered, there is an advantage that it is possible to accurately determine whether the state of the battery cell is in a degradation accelerated state.
