摘要
Abstract
GB/T 31486-2015"Electrical performance requirements and test methods for traction battery of electric vehicle"is a critical standard in the field of traction battery electrical performance.The new energy vehicle and traction battery industries have seen rapid development in recent years,leading to a shift toward"cell to pack"(CTP),and a deeper understanding of real-world operating conditions.In addition,advancements in battery performance have surpassed the levels established in the 2015 version.Consequently,China published the revised GB/T 31486-2024 in 2024.The updated standard,implemented on April 1,2025,is a core document in the traction battery sector and is important for product development and validation.This study analyzes the background and key technical updates of the GB/T 31486-2024 standard,highlighting its differences from the 2015 version.The revisions focus on three main aspects:(i)Alignment with"CTP"technology:test objects are shifted from modules to cells,with increased sample sizes to enhance consistency evaluation.(ii)Optimized test conditions:test parameters are optimized based on real-world operational data,and dynamic environmental adaptation termination mechanisms are integrated.(iii)Elevated performance requirements:The overall performance criteria are increased.Furthermore,GB/T 31486-2024 emphasizes coordination with domestic standards,such as GB/T 31467-2023,ensuring that test results more accurately reflect actual operating conditions.By upgrading technical specifications and innovating testing methodologies,the revised standards can drive enterprises toward improving product performance and consistency control,thereby providing vital support for the high-quality development of China's new energy vehicle industry.关键词
