摘　　要：采用危险源辨识方法,通过对各种危险源及其发生火灾的可能性分析,对电动汽车充换电站功能区域进行了划分,并列出了各个区域内的主要危险源,为火灾场景辨识提供依据。基于电动汽车充换电站内电缆、装饰材料及电池燃烧特性和FDS大涡模拟方法,建立了典型火灾场景,研究了不同火灾场景烟气运动情况、温度变化情况及能见度和CO分布情况,据此分析了电动汽车充换电站发生火灾时的火势蔓延情况及危险性,为电动汽车充换电站内有效进行火灾预防及指导人员疏散提供重要的技术支持。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 ca- ble, decoration materials and battery combustion, the FDS large eddy simulation method was used to build up the typ- ical 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 ana- lyzed, which provides an important technological support in effectively preventing fire and guiding evacuation in EV charging and swapping station.
