What Circularise covers
A battery passport is only as strong as its evidence
The public passport is the last step. The hard part is trusted supplier data, linked records and deciding what each audience can see.
Battery and material traceability
Link product records to sites, transactions and upstream evidence so values hold up.
Governed passport publishing
Publish QR-code views and keep sensitive commercial data to the right audiences.
Implementation workflow
From compliance requirement to operating system
Run your battery passport as an ongoing data workflow, not a one-time report.

2027 readiness
Four things to settle first
Start with supplier data: it is the one thing you cannot reconstruct later.
- 01
Confirm battery scope
Which product families, markets and customer contracts need a passport first.
- 02
Prioritise supplier data
Upstream fields are the hardest to reconstruct later.
- 03
Define access rules
Separate public, partner, customer and regulator views before data reaches a QR code.
- 04
Connect existing systems
Integrate ERP, PLM, LCA and compliance systems so the passport stays maintained.

When do EU battery passports become mandatory?
From 18 February 2027 for EV batteries, light means of transport batteries and industrial batteries over 2 kWh placed on the EU market.
What should battery passport software do?
Collect supplier evidence, connect it to battery and material records, manage access rules, and publish QR-code or API passport views that stay maintained.
What data is needed for a battery passport?
Typically battery identity, manufacturer, composition, carbon footprint, recycled content, responsible sourcing evidence, performance, durability and end-of-life instructions.
What happens to the battery passport when a battery is repurposed or remanufactured?
A battery that is prepared for reuse, repurposed or remanufactured must receive a new battery passport linked to the original passport or passports. Responsibility for maintaining the new passport transfers to the economic operator placing the modified battery on the market or putting it into service.
