Deepsea Challenger burns

Wow, pretty bad luck....

Lithium battery fires, even with sophisticated systems, they burn randomly it seems. Like they go nuclear after a certain set of conditions occurs, and then nothing much except clean up the mess afterwards, the damage is done.

 

Where did you find that the fire involved lithium batteries? According to this report the fire originated in the truck carrying Deepsea Challenger. http://io9.com/james-camerons-deepsea-challenger-damaged-in-transit-1720172542

 

THEY WERE TRANSPORTING IT OVER THE HIGHWAY ON A LOWBOY WITH THE BATTERIES IN?!?

<<Facepalm>>

 

Are you saying that Bill Engvall would present them with their sign?

 

The reports say that it started with the brakes overeating

 

An interesting picture. It is sitting on a flat bed, I suppose the brakes underneath could cause this fire way up on the sub?
The brakes did not burn the plastic wheel flap nor the tires.
Maybe so.

Think that wheel/tyre been changed out, there's some other pics with Fire-ies showing flat & cooked tyres. My Dad had an under bonnet brake fluid fire once, put it out before too much damage but certainly scorched the bonnet, seems plausible & the cradle is pictured elsewhere with tyres interfacing the sub in other areas- maybe one of those tyres caught in that area, the web on the uni beam of the cradle adjacent the rear axle shows some scorch as well, tyres love to burn once started.

 

There's one picture where the trailer deck has been removed over that wheel (clean square removed)

 

I'm not sure where you would expect them to put them, but a transport cradle that provided a bit more protection to the battery compartment would have been prudent. I would hope they were mostly discharged; and there should be a battery monitoring mode for transport and storage as well. A transport battery harness with dummy load and safety switch could provide automatic and manual discharge if a hazardous condition was detected. That could all be part of the cradle. Cooling the batteries would also seem prudent. Depends on the type of Lithium battery being used.

 

Can't tell whether the Li batteries or brakes are the culprit, but it does look like the biggest damage has occurred where the aft half of the battery pack is placed: http://www.deepseachallenge.com/the-sub/

 

Phil....you NEVER transport a DSV with the batteries IN...not Pb-acid, not Ag-Zn, and definitely Li-ion....Its like they have never read anything about highway shock loads...I don't know what to say...
