Abstract
A battery inspection method comprises charging a battery to a fully charged state, determining, when the charging is finished while the battery is in a fully charged state, deviation of an open circuit voltage (OCV) value of each of a plurality of cells included in the battery at a first time point after a preset first reference time has elapsed from a time point of finishing the charging while considering polarization voltage, and determining, according to a result of comparing the determined deviation with a preset first reference value, whether an internal short circuit has occurred in the battery on the basis of the open circuit voltage (OCV) value of each of the plurality of cells or a state of charge (SOC) of each of the plurality of cells.
