电动汽车安全新国标发布 2026年7月1日正式实施

Core Viewpoint - The newly revised national standard for electric vehicle safety (GB18384—2025) will be implemented on July 1, 2026, marking the first comprehensive revision since its integration in 2020, addressing emerging safety risks associated with rapid technological advancements in electric vehicles [1][2]. Group 1: Key Changes in the New Standard - The new standard mandates a physical disconnection between the high-voltage circuit of the vehicle and the rechargeable energy storage system, introducing a "one-button power-off" device as a physical disconnection mechanism, enhancing reliability and timeliness in accident rescue [2]. - Vehicles must be equipped with high-voltage or low-voltage maintenance disconnection devices, with high-voltage devices meeting IPXXB protection level requirements, ensuring that live parts drop to safe voltage levels within one second after disconnection [2]. - A new requirement for underbody scraping tests has been added, specifying a barrier of 150mm solid hemisphere and a test speed of 35 km/h, with no leakage, shell rupture, fire, or explosion allowed, while meeting insulation resistance requirements [2]. Group 2: Industry Implications - Since 2025, over ten safety standards for new energy vehicle technologies have been released or are under public consultation, covering areas such as power batteries, vehicle safety, intelligent networking, and key components, directly addressing consumer concerns [3]. - The implementation of the new standard is expected to enhance the overall safety control system for electric vehicles in China, providing authoritative technical basis for product access, quality supervision, and accident investigation, which is crucial for mitigating safety risks and solidifying China's leading position in the global new energy vehicle industry [3].
