See here (https://www.youtube.com/watch?v=rPefnJm_WeM) for what can happen while charging an EV.

Perhaps charge stations need to be placed only in every other parking spot!

Cells cooking off? Isn't the BMS supposed to avoid these conditions in any decent EV?

Well, yes and no.  Yes, the BMS is supposed to cut power at that point.  But thermal runaway is a thing.  That's why there's goo or something between the cells in many modern vehicles, it's something which interferes with the thermal runaway by smothering the chemical reaction if a cell cooks off.  Most just make it burn slower, but...

...Without it you get what you saw in the video.

Any thoughts on where this is and what kind of vehicle that is?

The plates appear to be Chinese.

Yeah it's in Dongguan in China, couldn't find the model or even the make of the vehicle though.

Yeah, I figured it was in China. Had that look to the area.  I was there in  Dongguan but in year  2007, way before they were so much into EVs.

I have  been all over that area,   Shenzhen to Guangzhou. Includes a night boat ride in the very lit up Pearl River.  (https://en.wikipedia.org/wiki/Pearl_River_(China)#/media/File:River_Pearl.jpg)

I have been to China / Hong Kong / Macau several times.

But how did you figure out it was Dongguan?  Have you also been there?

While checking out the video in the OP, I came across this video from a good old boy who rants about why the big freeze in Texas has ended the future of electric cars - at least in Texas. No big surprise here, although he does seem to think there might be a future for H2-powered cars.  :o  In any case I found this 10-minute long video rant kind of funny and entertaining, especially the presentation.  https://www.youtube.com/watch?v=4111nIN7GMQ

If you Google the plate number you'll come across the video posted in a few other places with Chinese description and they all say it was in Dongguan. I did find the "original" version on TheYNC which said it was in Shenzen, but that site is far from a reliable source (I would not suggest visiting it if you haven't been to it before, and certainly don't go on it if you're at work or have other people about).

Because H2 stations will magically have electric power?

I don't get the argument.

Many people consider Dongguan as being part of Shenzhen. Perhaps it was at one time.

BTW, I was in Shenzhen in early 1981. Total population was probably 50 people at the very most. A few families in a small fishing village.

I return in 2007.  By then, it looked larger than Los Angeles, CA.

Today's population in Los Angles is around 4 million. But ten million in Shenzhen.

Shenzhen is a very interesting place. It is very south, but is very northern in culture, food, everything. This is because it is the city they first experimented with capitalism. They sent many people down from Beijing to build up Shenzhen. They picked that location because it was close to Hong Kong. Capitalism was so successful there, that  the city grew in no time and then changed the rest of China.

BTW, the computers we are now using, most likely were built in Shenzhen.

Computer stores there are often ten stories high. One floor will sell only hard drives, another floor, only monitors, another, only keyboards, etc. Far different from anywhere else.
