EVs don’t combust spontaneously. If the battery of an EV is compromised or battery pack is pierced and lithium is exposed to air. Then that violent reaction (lithium oxidizing the air) will produce the fire you see.
I think this is from a training exercise though. Suspiciously empty lot. Some branding on vehicle might indicate test site. The idea here is that by covering the vehicle with the fire resistant blanket, the fire will consume all of the oxygen and eventually put it self out.
No. In fact they are typically quite safe but there are some edge cases that pop up given the size and power of the batteries. E.g. Recently it was reported in Florida that some EVs had similar battery issues as a result of hurricanes flooding them with salt water. Thats not a normal occurrence. It makes sense that salt water and batteries aren’t totally simpatico, but more importantly for this to happen you had to leave your car by the ocean in a hurricane, not a spontaneous thing.
Conversely I had a friend driving a brand new ford fiesta and one of the front wheels just came off at speed on the highway…
No, they do not spontaneously combust. They just burn differently. They electrolytically produce very large quantities of flammable vapors and oxidizers. Because they are not entirely reliant on atmospheric oxygen, it is extraordinarily difficult to extinguish them.
It takes 10+ times as much water to extinguish a battery fire as an equivalent petro-fuel fire.
As someone who doesn’t understand a thing about cars, and evs in particular- wat? Do they combust spontaneously?
