An electric vehicle which operates from a rechargeable battery. The rechargeable battery is contained within an enclosure such that an airspace exists between the rechargeable battery and an interior wall of the enclosure. An aerosol container containing an aerosol electrical insulator communicates with the interior of the enclosure so that when said aerosol container is discharged, the aerosol electrical insulator is released within the airspace to dampen any fire occurring with the rechargeable battery.
