China Advances National Standards for Electric Vehicle Battery Technologies -new Standards GB/T 38661-2020 and GB/T 31484-2015
5. February 2026China has recently reaffirmed and expanded its national standardization work for electric vehicle battery technologies, covering battery management systems, performance durability, recycling safety, and emerging solid-state battery components. Several standards fall under the administration of the Ministry of Industry and Information Technology and are managed by the National Automotive Standardization Technical Committee and its Electric Vehicle Subcommittee. These initiatives reflect China’s continued effort to regulate the full life cycle of traction batteries, from in-vehicle performance and safety to end-of-life dismantling and advanced material applications. Batteries and battery production equipment and components usually require CCC certification or battery registration in order to be approved for import and sale in China.
Among the relevant standards, GB/T 38661-2020 specifies technical requirements for battery management systems used in electric vehicles, while GB/T 31484-2015 defines cycle life requirements and corresponding test methods for traction batteries. In addition, a draft national standard on safety requirements for dismantling and crushing traction batteries is currently under development, alongside a draft technical specification for solid electrolytes used in solid-state batteries for electric vehicles, which is planned to take effect immediately upon release. These standards are being developed with contributions from major industry stakeholders, including leading battery manufacturers, automotive research institutes, and recycling technology companies, underscoring broad industry participation in shaping China’s regulatory framework for advanced battery technologies.
