BATTERY MANAGING APPARATUS AND METHOD THEREOF

A battery managing apparatus according to one embodiment of the present disclosure includes: 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.
