爆燃事故接二连三，电车真不如油车安全？

Core Viewpoint - The article discusses the increasing frequency of fire incidents involving electric vehicles (EVs), raising concerns about their safety compared to traditional fuel vehicles, particularly focusing on the role of lithium batteries in these incidents [3][5][6]. Group 1: Fire Incidents Overview - Recent incidents include a Li Auto MEGA, a SAIC Volkswagen Tiguan L, and a Xiaomi SU7 Ultra, all of which caught fire, with the first two resulting in total vehicle destruction but safe escape for occupants [3][4]. - The vehicles involved were equipped with ternary lithium batteries, which are noted for their higher energy density and associated risks [3][5]. Group 2: Fire Risk Comparison - Data from the National Fire Rescue Bureau indicates that the fire occurrence rate for EVs is 0.288 per 10,000 vehicles, while for fuel vehicles, it is 0.2 per 10,000, suggesting that the fire risk is comparable [6]. - However, the intensity of fires in EVs is reported to be significantly higher, with peak heat release rates reaching 11.6 MW and toxic gas emissions posing serious risks to occupants [7][10]. Group 3: Battery Safety and Technology - Ternary lithium batteries are more prone to thermal runaway compared to lithium iron phosphate batteries, with higher combustion temperatures exceeding 1100°C [11]. - The article highlights the need for improved battery safety measures, including better design of battery structures and real-time monitoring systems [11][12]. Group 4: Regulatory Developments - New national standards for electric vehicle battery safety are set to be implemented in July 2026, focusing on preventing fires and ensuring passenger safety during incidents [15][16]. - The standards include revised testing protocols for thermal diffusion and battery impact resistance, aiming to enhance overall vehicle safety [15][16].
