GB/T 31467.1-2015

This standard specifies test procedures for evaluating the performance, safety, and reliability of lithium-ion traction battery packs and systems designed for high-power applications in electric vehicles. It is applied by manufacturers and testing laboratories to assess battery characteristics such as power density, charge/discharge efficiency, and thermal behavior under demanding conditions like rapid acceleration or regenerative braking. The standard ensures that high-power battery systems meet operational requirements for hybrid electric vehicles (HEVs) and other electric vehicles requiring substantial instantaneous power output.
