1. A processor-implemented method for controlling a battery pack, the method comprising:
- verifying variance information of a physical quantity of each of a plurality of batteries, wherein the variance information corresponds to a variance in the physical quantity during a cycle, and the cycle comprises at least one of a full charge cycle, a full discharge cycle, a partial charge cycle, and a partial discharge cycle;
identifying a target battery among the batteries based on the variance information;
determining pack state information of the battery pack comprising the batteries based on state information of the target battery; and
controlling the battery pack based on the determined pack state information.
