Abstract：Based on the comparative analysis of the safety parts of domestic lithium-ion electrochemical energy storage standards GB 40165-2021,GB 44240-2024 and GB/T 36276-2023,the safety test requirements and test methods of the three standards are summarized,and the inconsistent parts between the standards are analyzed and summarized.The differences of application scope,term definition,cell test,module test and sample test among standards are pointed out.The three standards all involve lithium-ion batteries in electrochemical energy storage,but the scope of application and focus are different,GB 40165-2021,GB 44240-2024 are more focused on the safety requirements of batteries and battery packs,and GB/T 36276-2023 is more focused on the technical requirements and test methods of lithium-ion batteries.GB 44240-2024 and GB/T 36276-2023 two standards,in terms of safety requirements,the standard content is more repeated,increasing the difficulty of product certification of enterprises.In summary,these three standards are important national standards in the field of electrochemical energy storage,which complement each other and jointly promote the safety and development of electrochemical energy storage technology.In particular,the introduction of GB 44240-2024 mandatory energy storage battery safety standards can effectively promote the healthy development of the energy storage industry.
