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.

        Good point. I’m not sure. It may be that we’re (I’m) hearing more about Teslas catching fire because they’re the largest distributor in the US (and I live here). However, they’re not the largest in the world and I haven’t heard of this problem happening with other EVs (though they may be).

        Regardless, Elon Musk is a pompous charlatan and defrauder that deserves much worse than he’ll ever get. Bias be damned.

          Wow, you should look into the hundreds of ev car fires in China that happen for may more reasons than crashes. Such as charging the battery and just sitting there in traffic or just sitting in an ev car lot. BYD is one of the largest ev brands in China, and their shit just catches fire for no reason some times.

              Not all EVs need Li-Po batteries. They probably won’t be in the next couple of years. The cheap end of the market will use sodium-ion, and the more expensive end solid state lithium. Both have much better fire protection and puncture resilience than Li-Po. Both types of batteries are at the manufacturing stage, but aren’t in cars yet.

        No. This kind of safety issue isn’t universal to all lithium chemistries, much less other chemistries. If they do catch on fire, it isn’t self-oxidizing the way it is for Li-Po chemistry. Other types also have better resilience to punctures.

      All forms of high-density energy storage are dangerous, regardless of who manufactures them.
