Simple chemistry and physics dictate that putting water on an electric vehicle fire results on the fire making its own fuel.
The fire is using the vehicle's electric batteries to separate the hydrogen from the water ( H2O ) being used by the fire fighters.
.
The triangle of combustion is Heat + Fuel + oxygen. In order for the fire to be extinguished you have to remove one or more of the links from the Triangle of Combustion.
I could easily be wrong here, but I assume that the only part of the 'Triangle of Combustion' that can be attacked in these fires is the 'Heat' side. Therefore, pouring massive quantities of water eventually cools the batteries below the combustion threshold (even though it creates some oxygen in the meantime).
That having been said, I wonder if they could 'remove Oxygen' by deploying a 'huge non-flammable blanket' over a Tesla in order to smother the flame.
Food for thought... (I'm only asking for a 1% royalty)
Lithium is a monofuel, it can burn without oxygen. Added to this is that water makes it burn even more. The only way to put these fires out is to bury them in dry sand or earth.

Damn, I was hoping to retire on my blanket royalties.
Is there any way to talk the lithium into needing oxygen? You know, by calling it racist or something...
Alternatively, Teslas may need to be outfitted with automated 'Stop, Drop, and Roll' servos to deal with fires.
Darley fvehicle fire blankets
They work well. My fire dept bought two recently.
