Hurricane, flood, then fire
10/06/2022
In the wake of hurricane Ian, Florida has a new danger. EV batteries that have been waterlogged in the wake of the hurricane are at risk of corrosion, which could lead to unexpected fires, according to Jimmy Patronis, the state's top financial officer and fire marshal. "There’s a ton of EVs disabled from Ian. As those batteries corrode, fires start," Patronis tweeted Thursday. "That’s a new challenge that our firefighters haven’t faced before. At least on this kind of scale." |

Re: Hurricane, flood, then fire
Could be a big deal. I'm sure there are lots of flooded EV's there. Hopefully, they will make sure that they are not inside people's garages. Not much you can do about that unfortunately.

Re: Hurricane, flood, then fire
I guess the same flood danger applies to golf carts with lithium batteries? IDK. I did get emailed some pics of a flooded cart that has all the battery cables corroded off both ends.

Re: Hurricane, flood, then fire
I rescued sunken boats back in the 60's and even an hour or two in salt water would sever the battery terminals. Wherever the current flows, you will get massive corrosion. If they pull the power connectors in the flooded EV's, they probably won't catch fire.

Re: Hurricane, flood, then fire
The EV fire thing is new as they burn (apparently) when thermal runaway starts...and water isn't the answer.
OTOH.....gas powered vehicles are not immune from flood started fires. https://www.autoweek.com/news/a17108...-italian-port/ |

Re: Hurricane, flood, then fire
No vehicle is immune from it, but EVs have a special category all their own because the fire that starts in the batteries on these CAN NOT be put out with water.
The reaction of lithium and oxygen combined with any amount of heat creates a self sustaining fire that doesn't go out until it has burned away all of the fuel, which in this case would be the lithium and other substances that comprise the insides of the battery. Some fun facts here in the chemical datasheet for Lithium: https://cameochemicals.noaa.gov/chemical/999 |

Re: Hurricane, flood, then fire
Statistically, EV's are less prone to fire than ICE vehicles but the fires are harder to put out.

Tomato.....Tamato......
They all come with hazards. Then, nobody will accidentally die from carbon monoxide via leaving the engine on while parked in a home's integral garage. |
