Hundreds of thousands of electric cars have been recalled due to risk of spontaneous battery fires with no damage, recalls initiated due to a dozen or two such spontaneous battery fires occurring in parked, unplugged vehicles. The batteries in almost all cases were manufactured by LG Chem, and the cause of the fires was several potential manufacturing defects, including torn anode tabs and folded separators, that could lead to a short circuit condition when the battery cell expanded and contracted, such as after charging the car. Recalls included the Chevy Bolt, Chevy Bolt EUV, Hyundai Kona EV, Smart ForTwo Electric, Chrysler Pacifica PHEV, and some VW ID.4s. LG Chem's stationary battery packs for home/solar use were also recalled for spontaneous fire risk.
On April 25, 1996, Ford Motor Company announced it would conduct one of the largest recalls for a safety-related defect in the history of the U.S. Department of Transportation. The recall covered approximately 7,900,000 Ford, Lincoln, and Mercury vehicles in the U.S. from model year 1988 through 1993 for a defect in the ignition switch causing the cars to catch ablaze spontaneously (NHTSA recall number 96V-071).
Although battery fires can easily reach 1500C, and involve reactions that generate oxygen, meaning that depriving the fire of oxygen isn't enough to put it out. The best you can typically do is just let it burn itself out. This works better when your EV is parked outside the home.
The stove in your cabin (and you) are a far greater risk than a battery would be.
