Abstract
A battery pack includes at least one battery cell, an optical fiber sensing unit including a plate-type detection unit made of optical fibers horizontally and vertically arranged in a grid form. The plate-type detection unit is deformed by deformation of the at least one battery cell, a photoresistor to collect light reflected from the optical fiber sensing unit, and a controller configured to determine if swelling occurred in the at least one battery cell based on a resistance value with a change in an amount of light collected by the photoresistor.
