Abstract: To solve the problem that existing fire firefighting methods are difficult to extinguish electric vehicle fires effectively, a water spray thermal attenuation fire suppression system and a trailer-mounted water spray fire suppression system were designed. The effects of these water spray systems were evaluated via full-scale electric vehicle fire tests. Under the working conditions of the tests, the results indicated that the water mist thermal attenuation fire suppression system could effectively suppress and cool the flame at the vehicle chassis but had a poor cooling effect on the cockpit flame, resulting in the re-ignition of combustibles of the cab. The trailer-mounted water spray fire suppression system could not suppress the jet fire at the vehicle chassis, and its effectiveness in extinguishing the flame inside the vehicle needs to be further investigated.
