It's literally what Tesla recommends: > USE WATER TO FIGHT A HIGH VOLTAGE BATTERY FIRE. If the battery catches fire, is exposed to high heat, or is generating heat or gases, use large amounts of water to cool the battery. It can take approximately 3,000 gallons of water, applied directly to the battery, to fully extinguish and cool down a battery fire; always establish or request an additional water supply. If water is not immediately available, use dry chemicals, CO2, foam, or another typical fire-extinguishing agent to fight the fire until water is available. https://www.tesla.com/sites/default/files/downloads/2016_Model_S_Emergency_Response_Guide_en.pdf https://www.tesla.com/sites/default/files/downloads/2016_Mod...
