A newly awarded patent outlines an innovative, foam-based thermal runaway suppression system that’s built into an EV’s battery pack.The indisputable fact of the matter is that electric vehicles catch fire far less often — and far less frequently — than their combustion-powered brethren. Still, a number of highly-publicized early Tesla fires and poorly managed recall on the first-gen Chevy Bolt have linked “electric car” and “fire” in the minds of many Americans, and the ones who have been waiting to test the EV waters until a better safety solution came along are going to absolutely love this latest setup from Chrysler parent company Stellantis.MoparInsiders is reporting on a new Stellantis patent awarded on a proactive battery safety system that’s designed to stop thermal runaway (read: fire) before it can cascade through an entire EV battery pack.Rather than relying solely on passive barriers or post-event containment, Stellantis’ freshly patented system uses strategically placed foam channels and deployment mechanisms that can flood the affected cells with high insulation foam when abnormal heat is detected in a cell, isolating the problem area and dramatically slowing (if not outright stopping) the chain reaction that leads to catastrophic battery failure.</div>

Stellantis has been awarded a patent for an innovative foam-based thermal runaway suppression system for EV batteries. This system aims to enhance safety by using foam channels to isolate and cool affected cells, preventing fires. Despite stepping back from some EV plans, Stellantis continues to innovate in battery safety, addressing concerns linked to electric vehicle fires.
