Scope

Scope: This document specifies the models and nomenclature, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of high-rate sodium-ion batteries used for starting purposes. This document is applicable to the design, production, inspection, and use of sodium-ion batteries (hereinafter referred to as "batteries") for motorcycles, automobiles, and other vehicles requiring high-rate discharge power for starting. Main technical content: This standard applies to high-rate sodium-ion batteries used for starting purposes in motorcycles and automobiles. Technical requirements include: a clean and defect-free appearance with clear polarity markings; an open-circuit voltage of 7.2–16.0 V and 14.4–32.0 V for 12V/24V battery packs, respectively; discharge capacities at room temperature/high temperature/low temperature not less than 90%, 95%, and 80% of the nominal capacity, respectively; compliance with high-rate discharge performance at room temperature/low temperature; a cycle life of ≥1,000 cycles (≥10,000 pulses); and passing safety tests such as overcharging and short-circuit protection, as well as environmental adaptability tests including humidity, heat, and salt spray. The test methods cover electrical performance, safety, and environmental testing procedures. Inspections are divided into factory, periodic, and type inspections, with rules for sampling and judgment specified. Requirements for marking, packaging, transportation, and storage are also clearly defined.
