Section 25: Miscellaneous Subject: Tesla destroyed by fire Msg# 1159151

There are 61 gas vehicle fires for every 1 electric vehicle fire per 100,000 vehicles of each type. So, I guess you need to figure out which is worse: 61 per 100,000 not as hot but can explode violently (think Molotov cocktail) or 1 per 100,000 hotter.
In any event, I have never read a single positive word from you about EVs or Hybrids, solar, wind, or any other non-fossil energy. Just trying to offer a little balance on this forum. |

For reference, the above message is a reply to a message where: Seems there's plenty of elec vehicle promotional materials, by the mfgrs. as well as the govt greenies. Citing the Pros but leaving out the Cons. There's an absence of explaining how the EV battery fires are much hotter burning and are more intense, are much more difficult to extinguish, than ordinary IC vehicle fires. And the EV's are known to reignite both soon after extinguishing, and reigniting in the hours or even the days later. They pose new risks to first responders. However, other sources have been explaining the reasons how EV fires are quite nasty. Here's some quotes, examples of the problems. > March 2018 Fire extinguished but reignited in the tow yard 5 days later. [Tesla X] > May 2018 Fire extinguished but reignited while loading on tow truck and again reignited in the tow yard [Tesla S] > Dec 2018 Fire started in a Tesla, not being worked on and was not involved in a collision, spontaneously combusted in a tire shop parking lot, then reignited in tow yard. [Tesla S] “It’s a brand new car, I just got it three months ago, there’s only 1200 miles on the car,” the owner said > Risk of reignition leads to recommending that damaged EVs should be stored within a 50-foot clear radius area. > Nov 2020 NTSB report: lithium-ion batteries pose the risk of electric shock to emergency responders from exposure to the high-voltage components of a damaged lithium-ion battery. > further risk is that damaged cells in the battery can experience rapid and uncontrolled increases in temperature and pressure (thermal runaway), which can lead to hazards such as battery reignition/fire. > A major concern with the large battery systems used in EVs is that the thermal runaway of one cell can lead to a catastrophic fire in the whole battery system and re-ignitions even after visual flames have been extinguished. < The problem with EV lithium-ion batteries is the chemistry, which is different from earlier nickel-metal hydride hybrid batteries. > fumes from a burning lithium fire are highly toxic, capable of causing death or long term brain injuries. > Lithium burns at 2000C / 3632F – more than hot enough to melt steel. (underlines added) A similar problem has occurred in a large Tesla Megapack installation designed to serve the power grid in South Australia. One of the lithium Megapack battery banks caught fire and burned for about 3 days. |
