From 18 February 2027, the EU Battery Passport is a condition of placing covered batteries on the EU market. Whoever holds the approved record of what a battery is, what it’s made of and how healthy it is decides what buyers, authorities, repairers and recyclers see.
A record that lives with the battery.
A Battery Passport is a digital record linked to one battery. It brings together its identity, chemistry, performance, carbon footprint, materials and how it can be repaired, repurposed or recycled.1
The EU wants batteries that last longer, can be repaired and repurposed, and come back as material for new ones. That needs the right information, open to the right people, for the whole life of the battery.1
Our engine builds a battery’s identity against live regulation and standards. It reads maker documents, reconciles and calculates what the evidence supports, then publishes the passport to DPPcode.org.7
It reads maker documents, reconciles conflicting values and runs bounded calculations, labelled as calculated. Each result stays tied to the right battery.
Identity, chemistry, performance, durability, carbon footprint, materials, safety and end of life. One approved record holds the facts, their evidence and who may see or change them. That is a governed product identity.
The maker is best placed to start a battery’s record. Built once, it follows the battery to every buyer, operator, repairer and recycler and changes as the battery ages, instead of being rebuilt by each one.1
THE RECORD TRAVELS
WHAT MAKERS CAN DO NOW
Build it once. Keep it current.
The category sets the duty. LMT and EV batteries need a passport at any size, industrial batteries above 2 kWh. Check the finished battery’s category first.1
Some facts only the maker holds. Manufacture date, renewable content and internal resistance appear in 2 or 3 of 20 public document sets. Name an owner for each fact.5
Plan for the battery’s life. State of health, status and second life update the record after sale. Who may read and update each part is set by Annex XIII and the access rules still to come.1,4
The BYD record is a public-data demonstration by ActivateDigital, not issued by BYD. Lifecycle and Activate&Measure in beta; Activate&Track for approved accounts. A passport alone does not establish legal compliance.
