Tests in Spain show the blanket greatly reducing the electric vehicle fire heat and the fire rekindling when oxygen is reintroduced

As much as there is no party without music, there is no fire without oxygen. Water, foam, powder, and other fire fighting methods focus precisely on separating this gas from any heat source. Anyway, that is really hard to do with Li-ion battery packs. Fires involving them are notoriously hard to put out, but not with a giant fire blanket, as the video above shows.
Bridgehill developed it using materials such as quartz, but the technology involved is not as important as the size of this thing. It is 6 m (19.7 ft) wide and 8 m (26.3 ft) long. That means it can cover almost any car currently in the market. It is also heavy: 28 kg (61.7 lb).
Almost 15 minutes after the fuel burner started the fire, the Nissan Leaf already registers only 120ºC (248ºF). The firefighters give it five more minutes and remove the blanket when the car is at 107ºC (224.6ºF) – ten minutes after they first placed the equipment over the burning EV. When they do that, we can still see the tires in good shape. That is an indication the blaze did not have time to damage them. Yet, the fire restarts almost immediately.
