Abstract
With the rapid proliferation of new energy electric vehicles, particularly in typical scenarios such as electric vehicle charging stations where EVs are densely concentrated, any fire outbreak could trigger severe chain-reaction consequences. To address the need for efficient emergency response to fires at EV charging stations, this study conducted full-scale electric vehicle fire experiments. Through comparative analysis of temperature variations, heat radiation flux, and flame infrared imaging, the effectiveness of three fire suppression techniques(compressed air foam, water mist, and fire blankets) was evaluated. Experimental results demonstrate that compressed air foam effectively cools flames and isolates oxygen to extinguish fires with excellent anti-reignition performance, albeit requiring substantial quantities. Water mist shows strong inhibitory effects on EV fires and effectively reduces smoke emissions, yet struggles to fully eliminate fire sources. Fire blankets prove effective in blocking fire spread and isolating burning vehicles from unaffected ones.
