Abstract
An apparatus for managing a battery includes a voltage sensor that measures a voltage of a battery cell mounted on a vehicle, and a processor that determines a short circuit risk of the battery cell. The processor may determine a self-discharge current of the battery cell during a self-discharge period in which a voltage drop of the battery cell occurs, determine an average voltage of the battery cell during the self-discharge period, determine a total self-discharge resistance of the battery cell based on the self-discharge current and the average voltage, determine a short circuit resistance of the battery cell based on the total self-discharge resistance, and notify the short circuit risk based on a fact that the short circuit resistance is less than a threshold
