1. A battery managing apparatus comprising:
a profile acquisition unit configured to obtain a battery profile representing the relationship between voltage and capacity of the battery;
a profile determination unit configured to adjust a preset reference positive electrode profile and reference negative electrode profile to correspond to the battery profile and determine the positive electrode profile and negative electrode profile of the battery; and
a control unit configured to calculate the lithium loss rate of the battery based on the positive electrode profile, calculate the negative electrode side-reaction rate of the battery based on the battery profile, and calculate the positive electrode side-reaction rate of the battery based on the lithium loss rate and the negative electrode side-reaction rate.
