Stellantis Patents the 'Ejecto-Battery'—Because Why Put Out Fires When You Can Just Drop Them?
Stellantis is finally leaning into the action-movie aesthetic by patenting a system to physically eject overheating batteries from their EVs. It is a brilliant, if slightly explosive, solution to the problem of turning your car into a lithium-ion barbecue.
When a standard lithium-ion battery enters a thermal runaway state—basically, a chemical chain reaction where the heat refuses to chill out—it becomes a fire that even industrial-grade extinguishers politely decline to fight. Stellantis, the parent company behind Dodge, Jeep, and Chrysler, decided that if you can't stop the heat, you should just toss it out the back door.
The patent details a system where a driver can trigger a rapid release mechanism using a button or touchscreen. Once engaged, the car severs the high-voltage connection and uses pyrotechnic fasteners or a sliding rail system to literally shove the burning pack onto the asphalt. The vehicle then switches to a low-voltage backup battery to crawl a few yards away to safety.
While this sounds like a scene from an 80s spy film, it leaves some awkward questions. Dealing with a five-hundred-pound slab of molten metal left in the middle of a highway is a logistical nightmare for road crews and local wildlife alike.
It is truly a marvel of modern engineering to design a vehicle that is essentially a high-speed toaster with a built-in self-ejection feature. One has to wonder if the next step is a parachute for the entire chassis or if we should just start carrying marshmallows in the glove box for the inevitable road-side meltdowns.
