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 ...

Summary of Electric Vehicle Battery Safety Standards Conference Industry Overview - The conference focused on the electric vehicle (EV) battery industry, specifically discussing new safety standards for power batteries set to take effect in July 2026. [1][21] Key Points and Arguments - **Current Battery Safety Performance**: Only a few leading companies (C Company, B Company, and Yiwei Lithium Energy) have products that can achieve 30-60 minutes without burning or exploding, while less than 10% can meet the two-hour standard. [1][4] - **New Safety Standards**: The new national standard requires that after a thermal runaway event, the battery pack must not catch fire or explode for at least two hours, with all temperature points remaining below 60 degrees Celsius. This is a stricter requirement compared to previous standards. [2][21] - **Material and Technology Improvements**: Enhancements in battery safety hinge on material systems and technological applications, including optimizing electrode material density, improving separator heat resistance, and enhancing thermal runaway protection materials. [1][5][6] - **Solid-State Batteries**: Solid-state batteries show significant safety advantages, capable of achieving over 10 hours without fire or explosion, with temperature control below 60 degrees. This technology is seen as a future direction for the industry. [3][19] - **Industry Restructuring**: The new standards aim to regulate liquid battery safety, promote industry consolidation, and accelerate the commercialization of solid-state batteries. [3][21] Additional Important Insights - **Battery Management System (BMS)**: The BMS must monitor battery parameters in real-time to prevent misjudgments or omissions, emphasizing the importance of advanced chip selection. [14][15] - **Challenges in Material Development**: The transition from artificial graphite to silicon-carbon/silicon-oxide for anode materials faces challenges such as volume expansion, which can lead to failures. [9][10] - **Electrolyte Improvements**: There is significant room for improvement in electrolytes, particularly through the addition of flame retardants to enhance safety. [12] - **Impact of New Standards on Suppliers**: The new standards may lead to some suppliers being unable to continue production due to insufficient R&D capabilities or manufacturing processes. [32] - **Consequences of Non-Compliance**: Batteries that do not meet the new standards will not be allowed to be installed in vehicles, leading to potential fines and brand damage for manufacturers. [19][33] Conclusion The conference highlighted the urgent need for the EV battery industry to adapt to new safety standards, emphasizing the importance of material innovation and technology upgrades to ensure compliance and enhance overall safety. The shift towards solid-state batteries is seen as a critical step in achieving these goals.
