Burning Batteries Would Eject From EVs in New Stellantis Patent
The patent would let a vehicle drop a battery pack after a fire starts, and officials say lithium-ion fires can take tens of thousands of gallons of water to extinguish.
- Stellantis recently filed a patent application for a "High-Voltage Battery Quick Release System For Vehicle," aiming to mitigate risks from EV-battery fires by separating the battery from the car.
- Because EV-battery fires are notoriously difficult for first responders to extinguish, the automaker designed this system to physically disconnect the battery pack during an emergency.
- The mechanism either drops the battery under the vehicle or uses explosive bolts to force it out, allowing the Dodge car to move a short distance using its 12-volt source.
- Although the car remains safe, analysts point out this process leaves a burning battery behind, potentially creating hazards in parking lots or near other structures.
- While Chinese engineers previously explored similar ejection concepts, this North American patent remains theoretical, and industry experts remain skeptical about the feasibility of deploying such volatile technology.
