首提不起火不爆炸，“最严电池安全标准”加速技术洗牌

Core Viewpoint - The newly released national standard for electric vehicle batteries, GB38031-2025, introduces the world's first requirement that batteries must not catch fire or explode after thermal runaway due to internal short circuits, significantly enhancing safety standards in the industry [1][6]. Group 1: New National Standard Details - The new standard will be enforced for new model approvals starting July 1, 2026, and for existing approved models from July 1, 2027 [1]. - The standard includes 17 testing items for battery packs or systems, with significant revisions to the "thermal diffusion" test and the addition of a "bottom impact" test [2]. - The "thermal diffusion" test now includes internal heating as a trigger method, alongside external heating and puncture methods, and specifies temperature requirements and testing conditions [2]. - The new standard mandates that batteries must not catch fire or explode during thermal runaway, a significant upgrade from the previous standard which only required a warning signal five minutes before such events [2][6]. Group 2: Industry Impact and Opportunities - The implementation of the new standard is expected to accelerate technological upgrades in the industry, ensuring consumer safety and promoting high-quality development of the electric vehicle sector [4]. - The new standard sets a unified technical benchmark for global battery trade, potentially reducing trade friction caused by differing safety standards and encouraging collaboration with regions like the EU and North America [4]. - The standard is likely to drive the Chinese battery industry towards a technology-intensive transformation, with solid-state batteries emerging as a key area for innovation [4]. - Leading companies with technological advantages may benefit, while smaller firms could face challenges, leading to potential market consolidation [4]. Group 3: Industry Consensus on Battery Safety - Industry leaders, including CATL and SAIC-GM-Wuling, acknowledge that battery safety has become a consensus, emphasizing the need for collaboration between automakers and battery manufacturers to meet the new standards [5][6][7]. - The new standard's requirement for batteries to not catch fire or explode is seen as a conditional requirement that aligns with current technological capabilities and ensures user safety in most scenarios [7]. - Companies are expected to undertake significant technological iterations in battery cell design, battery pack structure, and overall vehicle safety systems to comply with the new standards [7].
