Present situation and prospect of lithium-ion traction batteries for electric vehicles domestic and overseas standards

With the rapid development of electric vehicle industry, standardization of electric vehicle traction battery is more and more attracted attention at home and abroad. This paper summarizes the recent domestic and overseas lithium-ion battery standards ISO 12405 series, IEC 62660 series, SAE J 2929, UL 2580, VDA 2007 and QC/T 743-2006. Various standard test content, test coverage, test results decision criteria, temporary problems and prospects of lithium-ion batteries standard were summarized and analyzed. Comparing the gap between the domestic and overseas standard of lithium-ion traction batteries for electric vehicles, opinions and suggestions development of China's lithium-ion traction battery standards were put forward.
