California firefighters had to douse a flaming battery in a Tesla Semi with about 50,000 gallons (190,000 liters) of water to extinguish flames after a crash, the National Transportation Safety Board said Thursday.

In addition to the huge amount of water, firefighters used an aircraft to drop fire retardant on the “immediate area” of the electric truck as a precautionary measure, the agency said in a preliminary report.

Firefighters said previously that the battery reached temperatures of 1,000 degrees Fahrenheit (540 Celsius) while it was in flames.

The NTSB sent investigators to the Aug. 19 crash along Interstate 80 near Emigrant Gap, about 70 miles (113 kilometers) northeast of Sacramento. The agency said it would look into fire risks posed by the truck’s large lithium-ion battery.

    Firefighter here. Sometimes a better and less harmful option is to let things burn and protect the area. I went to a semi wreck that was hauling diesel and on fire on its side in the grassy median about 100’ away from a storm drain. Trying to put that out with just water would have become an environmental nightmare if all that fuel would have gotten washed into the storm system.

      “But electric bad” is what this kind of news will make rednecks think, and they will over sentionalize the conflagration of an ev battery

        My primary is a prius and I’ve done auto work and tech repairs for like 25 years now.

        I’m not buying an all electric EV, yet. They’re still wasteful and heavy and the battery tech isn’t quite good enough. EV’s pretty much have a life of 15 years on them (after going through tires faster) and then off to the junkyard once the battery goes out. I have high hopes for the solid state batts from Samsung hitting some production EV’s in 2027, though. Lighter, faster to charge, and longer lifespans. Until that, I’m sticking to hybrids, where the battery is less than 100 pounds, cost a few grand instead of $15,000 and you can swap one out at home in an afternoon with no special/expensive equipment.
