Several have come to the conclusion that the battery pack did not burn for given reasons.... if so, then how do you explain the melted body which would require a lot of energy to melt?

look up step and touch potentialNo. The runoff is obviously grounded. You need a closed circuit to receive an electrical shock.

Neither step potential nor touch potential is worsened by stepping on conductive water on top of the conductive ground. Step potential is also completely irrelevant at such low voltage, and I would think that the fire fighters have enough sense to not go up and lean against the car or supercharger. If they don't, they could be electrocuted with or without the water.look up step and touch potential
You obviously didn't look up step potential. it is exactly about a charge flowing on a grounded surface.Neither step potential nor touch potential is worsened by stepping on conductive water on top of the conductive ground.

What is that firefighter squirting at? Is he watering the grass way over yonder? Jeeze.
Yes, and the surface in question is grounded with or without water. Dry asphalt conducts electricity, wet asphalt conducts electricity.You obviously didn't look up step potential. it is exactly about a charge flowing on a grounded surface.
It's a pretty good hint that the transformer is completely unharmed. With some more training they would be more prepared and know where they could expect what voltages in which circumstances.As for the voltage, they have no idea what the voltage is, they know a car attached to a high voltage station is on fire, they don't know why, for all they know something shorted or grounded across the transformer and they have several kv in there.
The firefighters did exactly what they should have done in this situation. And I don't think they'd appreciate a bunch of amateurs telling them how to do their job.

Aluminium (which is used in the Model S) has a much lower melting point than steel (which is used in most other cars). 660C vs approx 1350C. Which explains why the result of this fire look much more extreme than maybe it is.
This might just be how any Model S will look after a fire in the interior of the car.

No, it doesn't. Just look at the results of the fires in 2013 when fire fighters dowsed the car with water. Far more intact. .
We need to stop perpetuating this myth that "battery electric car fires can't be put out with water." This is utter nonsense and could cost someone their life some day.
Yes. I believe the laws of nature don't change overnight.We are all learning, and eventualities not envisaged will come up. It's the nature of early product cycle.
Devils advocate: If your Model S (heaven forbid) was on charge and caught fire, would you personally just spray it with water whilst the power was still on?
And even when severly damaged battery packs don't burst into flames like gas tanks do. They take a while to get going.
Again show me the documentation that says this is Tesla approved procedure WHILST THE CAR IS PLUGGED IN.

I feel fairly educated on this, I don't think EVs are any more dangerous than ICEs, but I wouldn't.
I'd get my family clear and just let it burn.
If the high voltage battery becomes involved in fire or is bent,
twisted, damaged, or breached in any way, or if you suspect that
the battery is heating, use large amounts of water to cool the
battery. DO NOT extinguish fire with a small amount of water.
Always establish or request an additional water supply.
WARNING: When fire is involved, consider the entire vehicle energized and DO NOT TOUCH any part of the vehicle. Always wear full PPE, including SCBA.
WARNING: Regardless of the disabling procedure you use, ALWAYS ASSUME THAT ALL HIGH VOLTAGE COMPONENTS ARE ENERGIZED! Cutting, crushing or touching high voltage components can result in serious injury or death.
Yes. I believe the laws of nature don't change overnight.
