Abstract
A method for detecting thermal runaway of a cell includes: positioning a battery pack having multiple cells in an automobile vehicle; measuring a cell voltage of the multiple cells at a predetermined sample rate; and identifying if the cell voltage decreases and modulates coincident with a cell surface temperature increase indicating initiation of a cell short.
