There was an article some time ago about how this is handled for a normal sized car like a model S. Basically they put out the flames with traditional foam spraying, then dump the whole car in a large container with water. Let it sit under water for a few days until the battery fire is done. The battery fire is self sustaining, so only way to stop it is large amounts of continuous cooling for a long time. That's what the water container is for. At least that's the method used in the Netherlands. Which obviously isn't practical for a semi truck sized fire.
