电动自行车新国标修改完善近200个重要指标条目

Core Viewpoint - The Ministry of Industry and Information Technology has announced a revised mandatory national standard for electric bicycles, which will take effect in two phases: production on September 1 and sales on December 1. The new standard aims to enhance safety and performance while reducing risks associated with electric bicycles. Group 1: Safety Enhancements - The new standard aims to reduce fire hazards by optimizing fire-resistant technology indicators, limiting the plastic weight ratio to below 5.5% of the total vehicle weight, which will slow down fire spread and reduce toxic gas emissions during a fire [1]. - Traffic accident risks will be minimized by imposing strict limits on the maximum motor speed and enhancing braking performance, reducing the maximum braking distance to about half of the previous requirement [1][2]. - The standard includes measures to prevent illegal modifications by improving technical indicators for battery packs and controllers, thereby raising the threshold for unauthorized alterations [1]. Group 2: Performance Improvements - The overall safety performance of vehicles will be enhanced through dynamic monitoring requirements for battery status, allowing consumers to identify and address issues promptly [2]. - The weight limit for lead-acid battery models has been adjusted from 55 kg to 63 kg, enabling a range of 60-70 km, which reduces charging frequency and improves user experience [2]. - The requirement for pedal assist devices has been removed, increasing practicality and providing consumers with more model options while also saving production costs [2].
