电动自行车新标准引讨论 为啥限速？带来哪些积极影响？

Core Viewpoint - The new standard for electric bicycles, effective from December 1, limits the maximum speed to 25 km/h to enhance traffic safety and reduce accidents [1][2]. Group 1: Speed Regulation - The new standard maintains the maximum design speed of 25 km/h, which was also present in the 2018 version, and adds a requirement that the motor must stop providing power if the speed exceeds this limit [1]. - Many currently used electric bicycles exceed this speed due to the performance capacity of their motors, allowing for illegal modifications [1]. Group 2: Safety Considerations - The speed limit aims to reduce traffic accident risks by ensuring that vehicles cannot exceed the speed limit, thereby shortening braking distances and lowering collision risks [2]. - The new standard includes technical requirements such as the motor's no-load back electromotive force and inductance value difference coefficient to ensure compliance with the speed limit [1]. Group 3: Anti-Tampering Measures - The standard introduces measures to prevent illegal modifications, including improved anti-tampering technical indicators and testing methods, which raise the threshold for modifications [2]. - The implementation of a "one vehicle, one pool, one charge, one code" system is expected to significantly reduce or eliminate modification behaviors [2].
