A system and method to prevent fires in electric vehicles. The system reduces thermal runaway in vehicle battery pack by controlling nitrogen-enriched air (“NEA”) to a predetermined oxygen concentration to prevent fires and/or explosions in battery packs. The oxygen content of an electric vehicle battery pack is detected using an oxygen sensor. A controller determines whether the oxygen content exceeds a predetermined threshold. Based upon this determination, electrochemical gas separation and inerting system is activated to generate NEA. The system delivers the NEA to the battery pack until the oxygen content no longer exceeds the predetermined threshold.
