  • Laser-based method and system for triggering thermal runaway of a battery
    Patent number: 12174259
    Abstract: A method for testing a battery cell includes directing a laser radiation from a laser at a radiation-receiving location on a can of the battery cell to trigger a thermal runaway event. A power, a wavelength, and a beam size of the laser radiation are selected based on a test stability of the battery cell when triggering the thermal runaway event. The test stability includes a likelihood that the can will breach in response to triggering the thermal runaway event. The method also includes ceasing to contact the radiation-receiving location with the laser radiation in response to the thermal runaway event.
