According to a new report from federal investigators, a Tesla battery caught
fire twice after it was involved in a crash. But given the volatile nature
of lithium-ion batteries, perhaps it shouldn't have come as a surprise.
The National Transportation Safety Board (NTSB) today released a preliminary
report regarding a Tesla Model S that crashed in Florida, killing two and
injuring one. The report states that, after extinguishing a fire that
consumed the vehicle, the battery again caught fire while being loaded for
removal from the scene. The battery caught fire again when it arrived at the
storage yard. Both times, the fire was extinguished.
This isn't the first time that a Tesla battery has reignited following a
collision. It also happened following a Tesla Model X crash earlier this
year in California, which is still under NTSB investigation as well. While
that might stoke fear in those not familiar with EVs, reignition isn't only
feasible, it's something that needs to be monitored by all parties involved.
Lithium-ion fires can happen for a variety of reasons, but most boil down to
heat. EV batteries contain thousands of individual cells, and if even one
is punctured, the lithium inside will react violently with water in the air,
generating lots of heat and occasionally a fire. If you've ever seen a
YouTube video of someone stabbing a phone battery, that's what's happening -
- air gets in, reacts with lithium and starts a fire.
That's why batteries contain safeguards to prevent thermal runaway --
swollen batteries are the battery pack doing its best to keep those elements
from being exposed to air, even if the battery has already failed but not
yet ignited.

“时速115撞墙”——原报告的实情是,车子超速至116mph,然后司机看到路前方是一
个急转弯,带闪烁灯的标志上写着限速25mph,司机刹车减速,车子减速到86mph(安全
气囊打开时的记录),但方向失控,先是车轮和路边的curb发生碰撞,车子上curb之后
再跟墙发生碰撞;然后改变方向横跨5条lane,车轮再跟路的另一边curb撞一次,车子
最后被一根灯柱子拦住停下来。
首先,撞墙的时速肯定不太高(有curb、还有上curb之后的滑行缓冲了不少),其次是
撞墙未必是车头90度迎头相撞。
最重要的是一直在车里面坐着的两个人全死了;反倒是碰撞时被抛出车外(估计没系安
全带)的那个人重伤但是活下来了。
所以这说明Tesla车子发生车祸时,坐在车里的人反而最危险的。Tesla车子脆弱的结构
非但保护不了人,反而会成为致命的因素。
车祸当中不系安全带被抛出车外,反而比在车里坐着要安全,只有Tesla才能造出这种
设计和质量差到让物理规律反着来的奇葩产品。

但是tesla的电池是在车身底盘下,前后都有冗余,但是侧撞时就非常容易破损。这个

所以tesla车主要做的就是事故时,宁愿迎头撞上,也不要暴露自己的侧面。

Tesla用的是8142个3.4AH的松下18650型三元锂电池,三元锂 (镍钴锰) 密度大能有利
续航, 但是稳定性差容易燃烧. 而磷酸铁锂电池很安全但是能量低而且放电曲线太平
,不容易做电池控制系统。tesla用的每个锂离子电池中有一个极薄的隔膜将正负极隔
开机械变形后极易损坏,导到电池内部短路。所以这个火没法灭,只能等电耗光。
tesla到现在为止也没有出一个给各地消防员的灭火指南也是因为确实没有好的办法

volvo 明显意识到电池起火的危害,把电池放到前后左右都不会直接碰撞的地方,让安
全笼提供一定的保护空间,
而tesla侧面一撞电池就破了,马上起火。

tesla底盘对电池的保护不够,尤其tesla S
下一代tesla S估计要改进了
