Electric Vehicle Fire Blanket

Designed to contain Electric and Hybrid Vehicle fires, the EV Car Fire Blanket has been developed after many months of research and development.
The most common form of fire in electric or hybrid vehicles is when the high energy battery is damaged, or a manufacturing fault results in a short circuit. The battery can then go into “Thermal Runaway”, this is a phenomenon where damaged cells heat up rapidly to such an extent that a fire starts. The fire then compromises adjoining cells and a “domino effect” occurs spreading to the whole battery array.

Based on information assimilated from the fabric manufacturers technical database, definitive ISO testing is currently in progress (as at 03/12/2021).

Material Fire Test:

Based on information assimilated from the fabric manufacturers technical database, definitive ISO testing is currently in progress (as at 03/12/2021).

Fire Resistance Testing:

Samples were submitted to Intertek® and furnace testing to 800°C was conducted. The material, whilst compromised, retained is structure and was deemed effective for the intended purpose.

NOTE:

Whilst EV fires can reach core temperatures exceeding 1,300°C, the surface temperature of the vehicle body will be much lower than this. Once deployed the EV Car Fire Blanket reduces temperature rapidly by depriving the fire of Oxygen. This allows the EV Car Fire Blanket to perform effectively within its fire resistance ratings.
