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 incident involving the Ideal MEGA vehicle raises concerns about the effectiveness of battery warning systems and communication with vehicle owners regarding potential risks [1][2]. Group 1: Incident Overview - A fire incident occurred with an Ideal MEGA vehicle, resulting in total destruction of the vehicle and its contents, but no injuries were reported [1]. - There are conflicting reports regarding whether the vehicle owner received prior warning signals about battery issues before the incident [1][2]. Group 2: Battery Management System (BMS) - The BMS plays a crucial role in monitoring battery conditions, collecting data on temperature and voltage, and issuing warnings if thresholds are exceeded [2][3]. - Different automakers have varying BMS designs, leading to inconsistencies in how battery warnings are communicated to vehicle owners [3][4]. Group 3: Warning and Alarm Distinction - There is a distinction between "battery warning" (indicating minor issues) and "battery alarm" (indicating serious problems), with the former allowing continued vehicle operation under certain conditions [5][6]. - The probability of a vehicle experiencing a fault increases significantly if it continues to operate after receiving a battery warning [5]. Group 4: Regulatory and Safety Standards - The number of electric vehicle fire incidents has been significant, with 640 reported in the first quarter of 2022 alone [5]. - Recent updates to national standards for battery safety have introduced stricter requirements for thermal management and emergency response [5][6]. Group 5: Industry Insights - The effectiveness of battery safety measures relies on the design and implementation of BMS systems, which vary by manufacturer [6][7]. - Enhancements in BMS technology and battery design are essential for improving safety and reducing the likelihood of thermal runaway incidents [7].
