My Lightning burned to the ground

[ClevelandBeemer]

Your thinking is dangerous. YOU, unless you're a trained firefighter with the proper attire, and proper extinguishing equipment, should be running from your house and calling 911 if there is a vehicle fire of any type. Your are delusional if you think you're going to put out a vehicle fire, gas or not.

And yes, I have the expertise to say that.

You can park where you want to. That's your right. But ignoring FACTS to make them say what you want them to say is simply ridiculous.

I think my thinking is far from dangerous. As someone who frequently tracks vehicles, I have extinguishing equipment for fuel fires. Also, not all ICE fires are fuel based. There’s a lot I can do from the time FD is dispatched until the time they arrive.

Again if the HVB goes while in my garage, my home is nearly guaranteed to be going with it. Remember ICE fires last minutes vs EV fires which last hours.

BTW I fully recognize that EV’s are VERY safe, however in the very unlikely event there is a failure, I’ll be very glad my vehicle is parked outside.

I know the LVB is a perpetual annoyance for many people due to the moronic logic behind charging it. But this incident is not an LVB issue. That little LVB is not capable of rapidly incinerating the entire truck as we're seeing here. Based on the OP's description of the sound, timing, and the blazing inferno, this is quite clearly an HVB fire that quickly went into thermal runaway.

Feel free to continue being annoyed about the LVB. But stop trying to connect dots that do not connect to facilitate being annoyed about it.

Nobody knows for sure yet what caused this fire to start, the origin. You could be right that it will ultimately be determined it was an HVB failure.

The initial pop could have been a 12v battery short rupture/explosion, the other pops could have been the fuses in the HVB as their wires shorted out, OR all the pops could have been from the HVB fuses blowing due to a catastrophic HVB failure.

But, just to be clear, origin at the 12v battery is also a possibility.

1) this was not the "little" OEM AGM lead-acid 12v battery, it was an Ohmmu Lithium battery - LITHIUM BATTERY - and from seeing much smaller lithium batteries fail and explode into flame (lots of YouTube videos of that), one can understand how bad it could be if the Ohmmu failed, how intensely it could burn, and how fast it could spread to the rest of the truck.

2) people often underestimate how fast things burn to the ground once a fire is initiated. A house can be completely engulfed in flames in as little as 3 minutes, and that is without any lithium being involved.

3) once a fire spreads to the HVB wiring, which is all the orange wiring near the 12v battery compartment, up to the charge port DC pins, to the DC-DC converter which is under the Frunk floor, etc., the HVB fuses would pop from short circuiting, and as the fire spreads and heats up the HVB, the HVB lithium could become involved in the fire very quickly, there would be no cooling going on.

4) in the first picture there is a lot of burning at the front of the vehicle and the back, which doesn't really indicate one way or the other where the fire started.

5) the OP said the battery temp was normal - if this were a short in the HVB due to misalligned electrodes, like in the recall that affected around 1,000 Lightnings, I think there should have been indications of the HVB temperature being elevated as it began melting internal parts, based on what Ford said about that issue anyway.

6) regarding ICE vehicles and fires involving the 12v battery, remember the Ford ignition fires and recall? Well, to refresh everyone's memory, read about it here:

On April 25, 1996, Ford Motor Company announced it would conduct one of the largest recalls for a safety-related defect in the history of the U.S. Department of Transportation. The recall covered approximately 7,900,000 Ford, Lincoln, and Mercury vehicles in the U.S. from model year 1988 through 1993 for a defect in the ignition switch causing the cars to catch ablaze spontaneously (NHTSA recall number 96V-071). The recall occurred after years of concealment by Ford that saw parked Fords go up in flames across the country when the ignition switch developed an internal short circuit, overheated and caused the surrounding material to catch on fire. Some of the vehicles were parked in garages and burned houses when they ignited.

So no one should underestimate the potential of a 12v Ohmmu Lithium battery to cause a catastrophic fire.
