爆燃事故接二连三，电车真不如油车安全？

Core Viewpoint - The frequent fire incidents involving electric vehicles (EVs) have raised public concerns about the safety of new energy vehicles, particularly those equipped with ternary lithium batteries, which are linked to several recent accidents [2][3][4]. Group 1: Incident Overview - On the night of the 23rd, a Li Auto MEGA caught fire after sparks ignited from the vehicle's underside, leading to a total loss of the vehicle but allowing passengers to escape safely [2]. - A SAIC Volkswagen Tiguan L hybrid spontaneously ignited on an overpass, causing significant traffic disruption, but the occupants managed to escape unharmed [2]. - A Xiaomi SU7 Ultra caught fire after a collision, resulting in the death of the driver, highlighting the severe consequences of such incidents [2]. Group 2: Battery Safety Concerns - All three vehicles involved in the incidents were equipped with ternary lithium batteries, which are known to have higher risks of thermal runaway compared to lithium iron phosphate batteries [2][8]. - A report indicated that 90% of EV fire incidents are related to battery issues, particularly thermal runaway, which can occur due to collisions or battery overcharging [7][8]. Group 3: Fire Incident Statistics - According to the National Fire Rescue Bureau, the fire incident rate for EVs was 2.88 per 10,000 vehicles in the first quarter of 2022, which is comparable to the 2 per 10,000 rate for traditional fuel vehicles [4]. - From January 2018 to November 2024, over 1,730 fire incidents involving EVs were reported, with 305 recalls affecting approximately 4.62 million vehicles due to fire risks associated with power batteries [4]. Group 4: Fire Intensity and Risks - The intensity of fires in EVs is significantly higher than in traditional vehicles, with peak heat release rates reaching up to 11.6 MW, and toxic gases being released during combustion [5][6]. - The temperature of fires from ternary lithium batteries can exceed 1100°C, posing severe risks to occupants and first responders [8]. Group 5: Safety Standards and Regulations - New national standards for electric vehicle battery safety, effective from July 2026, will include revised thermal diffusion testing and additional safety measures to mitigate fire risks [10]. - The introduction of mandatory safety standards for vehicle door handles aims to ensure that doors can be opened in emergencies, enhancing passenger safety during fire incidents [11].
