China China issues national standards for downcycling of automotive traction batteries

China’s State Administration for Market Regulation and Standardization Administration on August 20 issued two sets of recommended national standards (GB/T) for the recycling of automotive traction batteries. Their names are as follows.

GB/T 34015.3-2021 Recovery of traction battery used in electric vehicle—Echelon use—Part 3:Echelon using requirement
GB/T 34015.4-2021 Recovery of traction battery used in electric vehicle—Echelon use—Part 4: Labels for echelon used battery products

Both of them will come into effect on March 1, 2022. Here is an overview.


GB/T 34015.3-2021 — Echelon using requirement


    • The GB/T sets out general and performance-related requirements on the downcycling (梯次利用) of automotive traction batteries, and general requirements on downcycled products.
    • The GB/T applies to the downcycling of cells, modules, battery packs and systems of waste automotive traction batteries.
    • The GB/T can be used for the downcycling of waste automotive nickel–metal hydride (NiMH) batteries.

The GB/T is established so that downcycling companies can determine based on the standards whether waste batteries are worth downcycling or should be recycled as materials.


GB/T 34015.4-2021 — Labels for echelon used battery products


    • The GB/T sets rules for labeling products using downcycled automotive traction batteries; namely, rules for the elements of a label, labeling requirements, where and how to put the label and what to state on the label.
    • The GB/T applies to labeling for products using downcycled waste automotive traction batteries.
