“as fireteams doused the vehicle with tens-of-thousands of gallons of water...”
Hmm, maybe dousing a battery fire with water is not the best strategy?
May be water was all they had. I agree...there needs to be something that stops these fires quickly. Foam, halon, sand, stick of dynamite...I don’t know.
“Chief, you said I could do the dynamite at the next EV fire! It’s my turn. I want to blow it up!”
There’s no practical alternative except cordon it off and let it burn.
Why, you afraid it'll make it catch more fire?
