储能强制性国标明日生效，首批过关“尖子生”有谁？

Core Viewpoint - The implementation of the mandatory national standard GB44240-2024 for lithium batteries used in energy storage systems marks a significant shift towards enhanced safety requirements in the industry, focusing on product safety characteristics and establishing legal entry barriers [1][2]. Group 1: Standard Overview - GB44240-2024 is the first mandatory national standard in the energy storage sector, emphasizing safety features and incorporating key testing items from international standards such as IEC, UL, and UN [1]. - The standard includes comprehensive testing requirements covering battery performance, electrical safety, mechanical safety, and environmental reliability, establishing safety benchmarks throughout the entire lifecycle of the battery [2]. Group 2: Testing and Certification - New testing items added in GB44240 include vibration, impact, puncture, and forced discharge, with stricter requirements for overcharging, increasing the total overcharge duration significantly [2]. - As of now, over 20 companies with more than 40 product models have passed the GB44240 evaluation, including leading battery manufacturers such as CATL, Envision, and others [2][3]. Group 3: Industry Impact - The rapid development of new energy and the increasing pressure for power supply necessitate the advancement of energy storage systems, with a reported 29% growth in installed capacity reaching 94.91 million kilowatts by mid-2025 [4]. - The implementation of GB44240 is expected to elevate safety from an optional consideration to a mandatory requirement, compelling manufacturers with insufficient safety redundancies to redesign their products, thus promoting a shift from cost-driven to safety-oriented high-quality production in the industry [4].
