Stellantis patents integrated EV fire-suppression system

Stellantis has secured a patent for an integrated fire-suppression system for electric and hybrid vehicles, a setup that could appear in future Jeep and Ram models. The design targets the risks associated with lithium-ion battery fires and thermal runaway, a pragmatic step that speaks directly to lingering concerns around battery safety.

According to the patent description, the system uses a reservoir of fire suppressant alongside a suite of sensors and actuators. When dangerous temperature spikes are detected, dedicated components puncture the container with the agent and channel it into the battery’s cooling circuits. The system only activates when the probability of a fire escalating is high.

Stellantis notes that EV fires are statistically rare, yet notably difficult to extinguish. The new setup is designed to contain a potential blaze early, before emergency services arrive. Comparable solutions have proved effective in specialized vehicle applications, though they haven’t been deployed at scale. A built-in safeguard that steps in on its own could be the reassurance that nudges cautious buyers toward an EV.

If the technology reaches series production without significant penalties in weight or battery capacity, it could raise the safety bar for new models and make electric vehicles more appealing to shoppers.
