China's Ministry of Industry and Information Technology has published a draft rule on a digital identity system for new energy vehicle (NEV) power batteries, opening it for public comment until December 6. The draft, with 20 articles, sets a 24-digit national-standard code as the unique index linking design, production, sale, installation, repair, dismantling, recycling and reuse into one digital record.
Automakers carry two hard duties: upload each battery-pack code through the motor-vehicle certificate system, and provide owners with battery details such as producer, date, rated energy, warranty period and cathode type via the onboard system or an app. The rule encourages monitoring of in-use battery status. False or incomplete data faces penalties under existing interim measures, and the rule is slated to take effect in 2027.
The move is part of a broader push to build full-lifecycle traceability as NEV volumes and battery retirement rise, giving regulators and owners a clear view of each pack's history.
