1. A battery management apparatus, comprising:
a control unit programmed to operate according to each of a first setting and a second setting, the control unit configured to:
receive a differential profile, wherein the differential profile is based on a battery profile representing a correspondence between a voltage and a capacity of a battery, wherein a type of the received differential profile is either a first type representing a correspondence between a differential voltage for the capacity of the battery and the capacity of the battery or a second type representing a correspondence between a differential capacity for the voltage of the battery and the voltage of the battery;
determine whether to operate according to the first setting or the second setting based on the type of the received differential profile;
determine a target peak included in the received differential profile, wherein in the first setting the control unit is configured to determine the target peak according to at least one first rule and in the second setting the control unit is configured to determine the target peak according to at least one second rule that is different from the first rule; and
determine a state of the battery based on a behavior change of the target peak with respect to a reference peak preset to correspond to the type of the received differential profile.
