Abstract
A system for testing a battery cell includes a test fixture configured to enclose the battery cell, a battery cycler configured to alternately charge and discharge the battery cell, an antenna mounted on a surface of the test fixture, the antenna configured to detect an electromagnetic signature of the battery cell and generate a signal indicative of the electromagnetic signature, and a detection module configured to receive the signal and detect characteristics of the battery cell based on the signal.
