Abstract
The present invention relates to a system and a method of detecting swelling of a battery cell, which, when abnormal swelling is generated in a battery cell embedded in a battery pack, rapidly detect the abnormal swelling and control a supply of a power source to the battery pack to be blocked, thereby preventing a structural deformation of the battery cell and the battery pack and life shortening of the battery, and preventing an accident, such as ignition and explosion.
