The question of just how much water it takes to extinguish a fire in an electric vehicle (EV) battery has recently been addressed following a Tesla Model S fire that occurred on Eastbound Highway 50 in California over the weekend. According to the Sacramento authorities, the vehicle spontaneously caught fire, with no reported injuries. However, it did take a substantial amount of water, approximately 6,000 gallons, to put out the fire as the battery cells continued to combust during the incident.
