Re: Lithium Fire at EVTV and Boeing 787 Dreamliner

I'd say those batteries were justified in their explosion given the damage to the car. For the tree to go far enough into the front of the car to split the main pack apart and scatter modules all over the road, they were going entirely too fast for any public road.

Ignoring it's a Tesla, it's a wreck where a car hit a tree at a high rate of speed, caught on fire, and the people in the car got killed. Hate to say it, but this happens every day. The exploding batteries were a result of physical damage, the same as almost every other EV battery fire that has occurred.

Ah, yes, makers of the stealth electric bike.

Interesting about the issue of dousing water onto a lithium battery fire. I knew about water and Sodium but not Lithium.

Interesting that the dismantling guide for the i-MiEV recommends totally submerging the battery pack underwater for 72 hours, emphasizing fresh water and not salt water.

Wouldn't have anything to do with the record heat, would it? Article dated the same as the lithium fire.

Could be, if the AC broke on the same date, which can and has happened here before. There will probably be some kind of news follow-up as to the cause tho.

I think it's either a misquote or a misunderstanding on the fireman's part. IIRC, lithium battery fires with the cobalt (and possibly magnesium) chemistries may not be put out by water alone because the cells contain their own oxygen supply, but copious amounts of water are actually recommended to cool things down below the ignition point and also to keep the fire from spreading.

Edit: Good ol' Battery University: http://batteryuniversity.com/learn/article/safety_concerns_with_li_ion
They say that only "Lithium Metal" batteries react with water, not Li-ion, LiPO or the other more common chemistries.
