ONLY because of the name Tesla . Any other fires in power substations etc dont make worldwide news.Quote:

:)
being in the news doesnt make things newsworthy .
That's because they aren't of such magnitude. ;)Quote:

Vindum eventually replaced the Teslas with a gasoline-powered Audi from the insurance payout
"Gasoline driven cars don't catch fire in the garage when they're sitting there. And that's the difference," he said. "I don't worry about [my] Audi catching fire downstairs when it's not running."
I read about this fire in Stuff yesterday. Not sure I'd be looking at an EV anytime soon if they recommend not charging at home in the garage unattended or leaving it parked there fully charged. I suspect this applies to any BEV. Not sure how this applies to PHEVs
With the NMC and NCA battery chemistries the battery can combust, especially so if overcharged. Heat and overcharging of these types will cause battery degradation, and if you want to actually look after these batteries it should be a routine practice not to charge beyond about 80% on a daily basis, or to discharge below 10%.
The cheaper, less energetic (less energy dense) LFP chemistry doesn't suffer this same fire or degrataion risk, and can be safely charged up to 100% regularly. Given it is also cheaper, and more ethically and enviro acceptable without the Cobalt of the other varieties we can expect to see LFP (Lithium Iron Phosphate) become a lot more common in domestic cars, with the more combustible 'exotic' chemistries reserved for high performance and haulage vehicles.
The fire in the battery farm does seem odd, given LFP (which is weightier but cheaper) is the logical choice for a non-mobile application like a battery farm.
The system was being stress tested, so maybe they just pushed it a bit too far over spec. Overheating in this scenario is most likely if charging is done too quickly, but a backup reserve such as this really doesn't need to be fast charged, and can be trickle charged over days or weeks, which is easier on the batteries, and on the power grid.
Extract from lengthy epistle:
There have been around 40 known fires that have occurred within large-scale, lithium ion battery energy storage systems, according to Christensen’s research. Those incidents, most of which occurred in the past three years, date back to 2012, and include four fires at three facilities in the U.S. in Arizona, Wisconsin and Illinois.
A 2019 disaster at the McMicken battery plant in Surprise, Arizona, seriously injured four emergency responders and is the most profound incident at a big battery in the U.S. to-date. Utility Arizona Public Service owns the site, and Fluence had provided that battery system.
In Beijing, two firefighters died, one more was injured and another first responder was missing after responding to a fire in a lithium-iron phosphate battery, which was connected to a rooftop solar installation at a shopping mall.
Lithium-iron phosphate batteries are currently considered to be the safest form of lithium ion battery, because the structure of the material in its cathode doesn’t break down until higher temperatures compared to other types of batteries, for example, that contain nickel manganese cobalt.
The safety of large energy systems employing LFP batteries is currently being reviewed in light of recent developments.
