储能锂电池安全强制性国家标准解读
Interpretation of Mandatory National Standards for the Safety of Energy Storage Lithium Batteries
摘要
Abstract
Standard guidance is the key to high-quality industrial development.Currently,the lithium battery industry is developing rapidly,and China has become the world's largest producer and user of lithium batteries.However,safety accidents caused by lithium batteries have been frequently reported,especially frequent fire accidents in energy storage power stations,which have attracted widespread attention.To standardize product quality and establish a solid safety baseline,China has issued two mandatory national standards,GB 40165-202 and GB 44240-2024,for lithium battery safety in the field of energy storage.According to the relevant provisions of the Standardization Law,if products produced,sold,or imported do not comply with mandatory standards,they will be investigated and disclosed,and even imposed criminal liability in accordance with relevant laws and administrative regulations.In order to better promote the correct understanding and effective implementation of mandatory standards,this paper introduces the scope of application of the two standards,as well as the division of their scope in the field of energy storage.It summarizes the existing international product standards and transportation standards for energy storage lithium batteries,and expounds on the selection of test samples from different levels of constituent units such as cells,blocks,modules,battery packs,and battery systems.It also analyzes and interprets key test items and requirements such as over-charging,squeezing,and needle punching.Through standards interpretation,it helps relevant parties to accurately understand the requirements of the standards,ensure the correct implementation of mandatory national standards,improve product quality and safety levels,and promote the high-quality development of the lithium battery industry.关键词
