2025.10. 30 本文字数：2683，阅读时长大约5分钟 作者 | 第一财经 梁昕 近日，上海一辆理想MEGA在行驶过程中，车辆底盘传来爆炸异响并冒出火苗，并在10秒内火势快速蔓延，最后 整车被烧得只剩空壳，车辆及车内财物完全烧毁，所幸无人员伤亡。 事件发生后，舆论持续发酵。有市场传言称，事故当天下午就报了故障码，并已经给涉事车主下了拖车单，但车 辆并没有到服务中心检查。很快，车主通过律师事务所发布严正声明，称"事故当天已经出现故障，下了拖车单 但是车主没有去修"等均为不实言论。究竟在起火事件前，电池预警/报警是否已经有效传递给车主提前规避风 险？这已经成为了社会关切的焦点之一。 基于此，第一财经记者联系到多位动力电池厂商、车企动力电池技术人员，绝大多数人认为，90%新能源汽车起 火事故与电池相关，尤其是电池热失控。为了减少热失控带来的损害，俗称"电池保姆"的电池管理系统 （BatteryManagementSystem，下称"BMS系统"）起到了关键作用。 "BMS系统最主要的功能是实时监控电池，并采集电池组温度和单体电池电压等数据，再根据采集到的数据，计 算判断电池是否处在安全的运行范围。"有车企电 ...

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].

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].
