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.
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.
So what you’re saying is that, in fact, all EV’s do have lithium batteries
