ZT：电车的电池跟核子弹差不多，买电车要三思。。。哈哈

What to do if your car catches on fire

First, you need to understand the difference between combustion-based and battery-based fires. They might look the same, but they’re actually very different. Fires in vehicles with batteries larger than a typical car battery (anything hybrid and up, in terms of electrification) can rage for much longer than normal fires.

If an electric car uses lithium-ion batteries (most do) and catches on fire, the batteries are at risk of a process called ‘thermal runaway’. This happens when the cells inside the battery pack short circuit after being punctured (as in, after an accident) or due to a manufacturing defect and start producing ‘Joule energy’, which is when current passing through a conductor produces thermal energy.


This extra heat energy is often hard to dispell faster than it’s being produced, which in turn induces a chemical reaction to generate more heat, creating the vicious cycle called thermal runaway.

Ultimately, this makes it incredibly difficult to stop an electric vehicle fire, because even if the flames get put out, the battery is unstable enough to keep producing heat and re-igniting the blaze.

Fire services need to drop thousands of litres of water over a burning EV to stop the flames and, sometimes they resort to submerging the vehicle in cold water for days to keep the batteries cool. The only other option is let the fire burn itself out because chemical-based extinguishers don’t work on battery fires.

电影里汽油车才天天爆炸，没见过电动车爆炸的

所以才说像核子弹，很难爆，不爆没事，但是一爆就是大事儿。。。哈哈

紐西蘭已經有氫氣燃料巴士了，隨時爆炸送你上西天，不要坐呀！

氢燃料车还好，但是加氢站爆炸频发。

就连废旧电池受到挤压也会起火爆炸，之前新闻不也说了么，市议会警告居民不要再把废旧电池扔进垃圾桶，因为会被垃圾车上的压实系统挤压后起火。所以电动车电池确实是有安全隐患的。最主要是现在各大厂家追求潮流玩命搞新技术，玩命追求大续航超级快充点，很多东西都不成熟就强行推出市场。

车内是防弹设计

我上面链接的文章里其实也说了，氢气比锂电池安全多了。。。哈哈

但是 tesla 重心低， 防撞性能好。



电池也是液冷的。

送来不喜欢电池车， 感觉和小时候的玩具车一样， 但价格不知道为啥搞了那么多。 看来包装和市场做的好， 价值就是不一样

好可怕，一旦着火就像火葬场一样。

混乱中...

本来锂电受到挤压就会爆炸，三年前有个新闻，有辆快递电动小货车追尾一辆公共汽车，本来车速没多快就是个小事故，结果电池板受碰撞起火，司机当场烧死。

吓死了，着火的话得把车泡冷水里好几天才能降温。。。哈哈，新西兰的消防队都不知道能不能做到 ...

Tesla 的电池是在车身底部的，这确实不是个好事……


Tesal 最近确实出了不少事……

还是回国吧

还是 3000 刀丰田小破车安全啊……

好，要买就买带弹射座椅的
