How an eco electric bus burns in an accident

Lithium ion batteries and some other chemistries are very unstable if they experience out of spec situations. Other such as LiFePo4 are much more stable but less energy density. I can personally attest to the amount of energy that is released when shorted out, just don't ask details but a metal enclosure project for the bus battery is on the list. Based on what happened on a way smaller ebike pack, the bus would burn totally down if the house bank went off.

Are you sure that's not a CNG-fueled bus whose roof-mounted gas cylinders are venting as intended to prevent a BLEVE?

The fire is getting pressure from some source, like from tanks,it is defiantly under pressure blowing sideways.

Either way that is scary. I just hope everybody made it out of there in time. Unfortunately, these new alternate fuel and/or BEV vehicles are still in their infancy so who knows what sort of incidents may pop up.
Where was this?

You have fires on buses no matter what fuel source,the newer buses have a automatic fire suppression system in the engine compartment and the turbos still will burn one down ask Greyhound or tour operators. EGR diesel engines make a bunch of heat when regenerating enough to melt the piston in some cases. I worry about that on my ISX 15 when I see the turbo boost at 50 PSI trying to expel the heat from the EGR

It's electric and so are these!

You notice the fire going up in this video and not sideways like a torch.

Just all of the sudden and they all get destroyed. All the school bus builders offer a BEV version now. Very concerning indeed. Oh, 3 fire apparatus builders are offering more or less a plug in hybrid but the same thing could happen to them too.

I would guess the 1st video to be pressurized CNG but the link was sent to me by a friend and it was labeled "eco- electric" & couldn't find any details. If it was in fact electric, if the bats were in explosion proof metal cases, that would explain the pressure - fire escaping out of metal box penetrations? There is an explosion during burn the shows a structural panel being blown off the the side? Who knows, it's a bad day at any rate...

Eco and EV are very different in their definitions! Maybe the Eco is CNG?

The EV buses I seen at Valley Metro the batteries are inside not on the roof .CNG tanks are on the roof for safety if something goes wrong like a leak the passengers are not gassed.

Not a Fire Bug but all I got one that first Vid is "Cool".

The CNG MCI commuter buses used in SoCal park and fly type busses, cng tanks are mounted in the luggage bays. I had my 5A thereto do some work and the Service writer showed me the new buses with the CNG tanks, but I was surprised to see there weren't any walls between the bays, just the framework trusses..

are we descending into social media brain drool?

no references, no sources, no legitimacy.

are scantily clad empty head influencers next?

If so, let's get on with it.

happy coaching!
