强化配件阻燃性能、提升防篡改功能 电动自行车强制性国家标准升级了

Core Viewpoint - The implementation of the new national standard for electric bicycles in China, effective from September 1, 2025, aims to enhance product quality and safety, addressing long-standing concerns in the industry and among consumers [1][2]. Group 1: Key Changes in the New Standard - The new standard includes over 200 revised technical indicators after extensive consultations and testing, which involved more than 160 technical discussions and 220 experimental verifications [1]. - Fire hazards will be reduced by optimizing fire-resistant technical indicators, limiting the plastic weight ratio to below 5.5% of the total vehicle weight, thereby slowing fire spread and reducing toxic gas emissions during fires [1][2]. - Traffic accident risks will be minimized by imposing strict limits on the maximum motor speed and enhancing braking performance, reducing the maximum braking distance by approximately 50% [1][2]. Group 2: Enhancements in Safety and Consumer Experience - The new standard aims to effectively prevent illegal modifications by improving technical indicators for battery packs and controllers, thus raising the threshold for unauthorized alterations [2]. - Overall vehicle safety will be enhanced through dynamic monitoring of critical safety information, allowing consumers to identify and address issues promptly [2]. - The weight limit for lead-acid battery models has been increased from 55 kg to 63 kg, improving the range to 60-70 km, which reduces charging frequency and enhances user experience [2]. Group 3: Implementation and Market Readiness - To ensure a smooth transition to the new standard, the Ministry of Industry and Information Technology (MIIT) and other departments have outlined specific measures, including accelerating the development and production of new standard vehicles [3]. - Four companies, including Yadea and Aima, have already obtained 14 new standard CCC certificates, indicating readiness for market supply [3]. - Consumers can identify new standard models by checking for the CCC mark on the vehicle, which confirms compliance with the new national standards [3].
