According to the announcement of the Ministry of Industry and Information Technology of the People’s Republic of China [2022 No. 23] on October 20, 2022, the electronic industry standard SJ/T11810-2022 “Safety Technical Specifications for Lithium-ion Batteries and Battery Packs for Electric Wheelchairs”, SJ/T11811 -2022 “General Specifications for Lithium-ion Batteries and Battery Packs for Electric Wheelchairs” is officially released. Both standards are under the centralized management and drafting of China Electronics Standardization Institute (CESI), and will start on January 1, 2023 officially implemented.
SJ/T11810-2022 “Safety Technical Specifications for Lithium-ion Batteries and Battery Packs for Electric Wheelchairs” and SJ/T11811-2022 “General Specifications for Lithium-ion Batteries and Battery Packs for Electric Wheelchairs” are both applicable to lithium-ion batteries for electric wheelchairs and battery packs. Electric wheelchairs within the standard range include electric wheelchairs for indoor or outdoor use, electric wheelchairs for carrying people up and down stairs, power-assisted wheelchairs, and other carrying tools with similar purposes. For indoor electric carrying tools/case-type electric wheelchairs Cars, etc. also refer to applicable. Among them, SJ/T11810-2022 specifies the safety requirements and corresponding test methods for lithium-ion batteries and battery packs used in electric wheelchairs, including electrical safety and environmental safety tests for batteries and battery packs, such as battery short circuit, overvoltage charging, and battery packs. Section overvoltage charging protection, water immersion and other tests. SJ/T11811-2022 specifies the electrical performance requirements and corresponding test methods for batteries and battery packs, including test items such as high and low temperature discharge, rate discharge and cycle life.
