Water is NOT GOOD for a lithium battery fire!
Any idea what the distance required is?And their polices state a certain distance away for the detached garage(s) or outbuildings too.
Actually, water cooling is the currently recommended fire fighting technique- everything is about keeping the fire as cool as possible. Getting the cells below 500C is critical. A new firefighting method from Sweden shows real promise. It is basically a pressure washer that can cut into the battery to inject water into the cell area to get the temperature down.Water is NOT GOOD for a lithium battery fire!
I've always suspected this, but I think the issue for some is timing. ICE's seem more likely to combust while in use, due to things like rodents nesting on exhaust manifolds or fuel system leaks in the engine compartment. But EV's seem more likely to spontaneously combust while charging in your garage, with your kids are sleeping in the bedroom above. Lower frequency, I had always suspected, but higher impact.However, the whole lithium car fire concern is grossly overblown, and not supported by fact.
Lithium EVs combust at 5% of the frequency of ICE vehicles, a number the adjusts for the differences in numbers. I.e. an EV is a (much) lower fire risk by a lot compared to a typical ICE.
You raise an interesting point, but I'm not finding actual data for fires while charging vs other sources. That said,I've always suspected this, but I think the issue for some is timing.

It would also be interesting to see how many fires are the result of crashes for ICEs and EVs. A lot of nuances in the data.
"one Tesla vehicle fire"You raise an interesting point, but I'm not finding actual data for fires while charging vs other sources. That said,
"From 2012 – 2021, there has been approximately one Tesla vehicle fire for every 210 million miles traveled. By comparison, data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation shows that in the United States there is a vehicle fire for every 19 million miles traveled.
In order to provide an apt comparison to NFPA data, Tesla’s data set includes instances of vehicle fires caused by structure fires, arson, and other things unrelated to the vehicle, which account for some of the Tesla vehicle fires over this time period."Note that the fire rate above includes all fires regardless of cause for Tesla vehicles.
All the best,
