Battery Passport Software
CircuLedger is the Battery Passport platform being built for the EU 2027 mandate — designed for manufacturers, EV brands, and recyclers, from first cell to circular economy.
The capabilities we're building — from data ingestion to QR-linked digital passports, aligned with EU Regulation 2023/1542.
Fully aligned with EU Regulation 2023/1542. Covers all battery categories — EV, industrial, and LMT — with automatic schema updates as the regulation evolves.
Monitor State of Health, State of Charge, capacity fade, and performance metrics continuously — from first cycle to end-of-life.
Every passport is cryptographically signed and anchored to an immutable record — tamper-proof, auditable, trusted by regulators and supply chain actors.
Map the full upstream supply chain — raw material origins, responsible sourcing documentation, and Art. 55 due diligence compliance.
Automated CO₂ declarations per manufacturing phase, meeting Art. 7 requirements — with value chain attribution and performance class calculation.
Every battery gets a unique QR code linked to its live digital passport — accessible to authorized stakeholders across the value chain in real time.
Four steps from manufacturing data to a fully compliant, live Battery Passport.
Integrate manufacturing, testing, and supply chain systems via API or no-code connectors. Structured and unstructured data ingested automatically.
CircuLedger structures data against the EU schema, calculates carbon footprints, and issues a cryptographically signed passport with a unique QR identifier.
Monitor your passport fleet in real time. Generate regulatory reports, share with auditors, and update records across the battery's full lifecycle.
At end-of-life, the passport guides second-life decisions, provides dismantlers with material data, and maximises value recovery for every cell.
Battery passports become mandatory for EV and industrial batteries above 2 kWh. Non-compliance means market exclusion across all 27 EU member states. We're building CircuLedger to help you get there in time.
CircuLedger was founded in 2026 in India by Sunil Verma, an engineer who saw how the global battery industry is struggling to keep pace with EU regulatory demands ahead of the February 2027 Battery Passport mandate.
We're pre-launch — the platform is being actively built, and I'm in conversation with prospective design partners ahead of wider rollout.
I'm building CircuLedger to be the connective tissue of the battery economy — a platform that turns raw battery data into living, compliant, trusted Battery Passports that serve every stakeholder from manufacturer to recycler.
Every data point is auditable, traceable, and accessible to authorized parties. No black boxes.
We track every regulation update so our platform stays ahead of your legal requirements.
Passports engineered to enable the circular battery economy — second life, repurposing, recycling.
Built on EPCIS, GS1, IEC standards — your data is never locked in to our platform.
