1. A battery management apparatus, comprising:
a measuring circuit configured to measure voltage and capacity of a battery cell;
a profile generator configured to receive a voltage value for the measured voltage and a capacity value for the measured capacity from the measuring circuit and to generate a battery profile representing a correspondence between the voltage value and the capacity value;
a profile converter configured to receive the battery profile from the profile generator and to convert the received battery profile into a battery differential profile representing a correspondence between the capacity value and a differential voltage value for the capacity value; and
a controller configured to:
determine at least one reference peak in the battery differential profile,
have a negative electrode profile and a negative electrode differential profile preset for a negative electrode of the battery cell,
adjust the negative electrode differential profile so that at least one target peak preset for the negative electrode differential profile corresponds to the determined reference peak,
adjust the negative electrode profile to correspond to the adjusted negative electrode differential profile, and
generate a positive electrode profile of the battery cell based on the adjusted negative electrode profile and the battery profile.
