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.
Is this 190 tons of water?
189.27 metric tons of water, so yes, rounded up, 190 tons.
Or roughly 2.5 average swimming pools and for those ex-redditors out there: 1.6 million bananas
Something tells me that we have to move away from cobalt/manganese chemistries for BEVs.
Solid state batteries are supposedly much more fire resistant.
Even the currently available LFP is much less violent.
Yes, true. Albeit they have worse energy density and some advantages as well.
How are you getting 189.27? 1 liter is 1kg, so it should be 190 precisely.
Because we are discussing metric tons of water where 264.17 US gallons = 1 metric ton of fresh water @ 4’C
Hmm… I’m gonna guess that water was much hotter than 4°C, what with being used to put out a fire and all.
What size is an average swimming pool area-wise? Or are you talking about Olympic size swimming pools?
Feet: 16’ x 32’ w/ a 4’ shallow end and an 8’ deep end filled with fresh water at an exact temperature of 39.2’F.
Metric: 4.9m x 9.7m w/ a 1.2m shallow end and a 2.4m deep end filled with fresh water at an exact temperature of 4’C.
