Abstract
A method for testing a battery component for leakage includes generating a sample from a battery component storing electrolyte using a Fourier Transform infrared (FT-IR) spectrometer, comparing absorbance levels of the sample at N predetermined frequencies to N predetermined thresholds, respectively, where N is an integer greater than one; and selectively detecting at least one of an electrolyte leak and generating an electrolyte concentration estimate in response to the comparison. The battery component is selected from a group consisting of a battery cell, a battery module, and a battery pack.
