"Electric vehicle battery fires are no joke. While statistically less frequent than gas car fires, they do mean a bad day at work for any fire department. Once one cell inside the pack ignites, it sets off a chain reaction that spreads from cell to cell and is extremely difficult to stop. This is known as thermal runaway, and scientists from all around the world are looking at ways to prevent it or mitigate its effects and keep occupants inside EVs safe."
"They demonstrated an automated system that shoots the battery from underneath the vehicle less than one second after it detects that thermal runaway has occurred. This makes a lot of sense because it keeps the car itself from burning down and the occupants inside safe, but it's also pretty alarming and potentially dangerous. In the demonstration video, they show the pack being jettisoned from underneath the car with a bang."
China tested an automated system that ejects an EV battery when thermal runaway is detected, expelling the smoldering pack less than one second after detection. The pack is projected between 10 and 20 feet (3–6 meters) away from the vehicle so occupants remain inside a safer cabin while emergency crews handle the isolated battery. Thermal runaway occurs when one cell ignites and triggers a chain reaction that spreads between cells and resists suppression. EV battery fires are less frequent than gas car fires but pose serious challenges for fire departments. The system was developed with Joyson Electronics and demonstrated by a Chinese vehicle safety research center.
