看完大伙对电池新国标的宣传，牛顿的棺材板盖不住了

Core Viewpoint - The new national standard GB 38031-2025 for electric vehicle batteries aims to enhance safety requirements, replacing the previous 5-minute escape time with a mandate for batteries to not catch fire or explode. This standard will be implemented on July 1, 2024 [1][2]. Summary by Sections New Testing Requirements - The new standard introduces three additional tests: thermal diffusion, collision testing, and safety testing after fast charging [1][4]. - The thermal diffusion test has been made more stringent, requiring batteries to not ignite or explode, and to ensure that toxic fumes do not harm occupants [4][10]. - The collision test focuses on the battery pack's bottom, but the impact force of 150J is considered insufficient compared to real-world scenarios [11][14]. Industry Response and Implications - The rapid development of the new standard, from research in December 2023 to completion in September 2024, marks a significant acceleration compared to previous standards that took 3-5 years [20][21]. - Many manufacturers already meet or exceed the new standards, which may lead to minimal noticeable changes for consumers [20][21]. Safety Enhancements - The new regulations aim to raise the baseline for battery safety, thereby protecting consumer life and property, and expediting the elimination of outdated production capacities [20][21]. - Despite improvements, the inherent risks associated with lithium batteries remain, as they are fundamentally reactive [8][10].
