摘要：
A method for detecting a minor short in at least one of a plurality of cells of a battery pack includes: a first step of measuring a voltage of at least one of the plurality of cells in a process of charging the battery pack; a second step of measuring a voltage of the at least one of the plurality of cells in a process of discharging the battery pack; and a third step of detecting the minor short in the at least one of the plurality of cells based on measurement results from the first step and the second step.
