Abstract
A system for evaluating a battery cell includes an imaging device configured to take a first image of at least part of the battery cell when the battery cell is in a first deformation state, and take a second image of the at least part of the battery cell when the battery cell is in a second deformation state. The system also includes a processor configured to analyze the first image and the second image, identify a first region of the first image that represents a suspected discontinuity, the first region corresponding to a portion of the battery cell, compare the first region of the first image to a second region of the second image, the second region corresponding to the portion of the battery cell, and determine that the suspected discontinuity is an actual discontinuity based on a difference between the first region and the second region.
