Abstract:

With the continuous application of lithium-ion batteries in EMU, subway, tram, and other rail vehicles, the safety and safety performance evaluation of lithium-ion batteries in use has always been a major concern, and major standardization organizations and application enterprises at home and abroad have developed the corresponding safety evaluation standards. This study briefly introduces the current guidance and normative standards in the field of rail transit at home and abroad, including TJ/JW 126—2020, Q/CRRC J39—2019, TJ/JW 127—2020, Q/CRRC J37.1—2019 and IEC 62928:2017, IEC 62619:2017. This section focuses on the battery monomer, module, and pack, compares and analyzes the battery safety performance evaluation methods of IEC and domestic standards, and presents the differences in the application scope, test objects, test methods, and test requirements at home and abroad. A comprehensive analysis of the three aspects of machinery, environment, and electrical safety requirements reveals that domestic standards for power lithium-ion battery setting test projects are relatively comprehensive and higher than the requirements of foreign standards, but the foreign standard test focus more on the electrical safety requirements. Finally, based on the differences in service and working conditions between the locomotive and electric vehicles, suggestions for further improvement in lithium-ion battery safety standards for rail transit are proposed to evaluate the rail transit battery system more scientifically and targeted and provide a crucial basis for the application and development of new energy storage systems in rail transit.
