Fire Risk Analysis on Electric Vehicle Charging and Swapping Station Based on Numerical Simulation Method
Based on the risk source identification method,this paper analyzes the possibility of various hazard sources and fire.The function areas of electric vehicle (EV) charging and swapping station were divided and the main hazard sources were listed inside each area,providing basis for identifying fire scene.According to the characteristics of cable,decoration materials and battery combustion,the FDS large eddy simulation method was used to build up the typical fire scenes.Then the smoke movement,temperature change,visibility and CO distribution on different fire scenes were studied.The fire spreading and risk when the fire occurs in EV charging and swapping station were analyzed,which provides an important technological support in effectively preventing fire and guiding evacuation in EV charging and swapping station.
