Create a digital passport for each battery on a shared network. The Traceability Ledger and Provenance Notary follow it from material sourcing to second life, while an ERC-721 NFT with the DID and VC Ledger carries a single, verified identity.
Turn a battery's fragmented life record into one verified passport from raw material to recycling.
01.
Anchor the origin of the cell. The Traceability Ledger records the sourcing of cathode materials and cells, so a passport can prove responsible sourcing from the first mine to the pack.
02.
Give the battery one identity. An ERC-721 NFT with the DID and VC Ledger carries the passport, so the battery holds a single verifiable identity across owners, vehicles, and second-life uses.
03.
Follow the whole life. The Provenance Notary anchors each state change from first fitment to end of vehicle life, so a battery's history is continuous rather than resetting at each handover.
04.
Prove the residual value. Signed state-of-health readings are anchored to the passport, so a second-life buyer prices the battery on a verified capacity record rather than a guess.
05.
Move value with proof. When a battery leaves a vehicle for stationary storage, the passport transfers with it, carrying its full history into its new role.
06.
Meet lifecycle mandates. Regulators read one verified battery history from material to recycling, so compliance with material and lifecycle traceability rules rests on the passport itself.
Follow a single battery from raw material sourcing through vehicle life to a proven second-life deployment.

Cerulea decomposes the battery passport into modular contracts. Each layer mints identity, anchors provenance, records health, and transfers to a second life without any single holder controlling the record.
The battery passport is a horizontal capability. Here is how different actors across the battery lifecycle put the shared record to work.
Prove responsible material sourcing and full lifecycle traceability on one passport, meeting regulatory mandates and lifting the resale value of every pack they build.
Key Asset Types
Read a verified capacity and provenance record before repurposing a pack, pricing residual value on evidence and proving the origin of recovered materials.
Key Asset Types
Query one verified battery history from raw material to recycling, replacing fragmented records with a single passport that evidences material and lifecycle compliance.
Key Asset Types
Whether you are bridging legacy PLM and materials systems or capturing signed readings from battery management systems, Cerulea routes both into one shared passport.
For battery and vehicle makers on legacy PLM and materials systems. Existing sourcing and build events are translated into passport records through the API gateway automatically.

Battery Passport Ledger
For battery management systems in the field. Each BMS signs a state-of-health reading and routes it directly to the passport through its device wallet.

Shared Passport Record
Building a battery passport network with NFT identity, material provenance, state-of-health records, and second-life transfer from scratch requires specialised engineers and long system integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects lifecycle traceability benchmarks. Writing custom ERC-721 passport logic, integrating materials and BMS data feeds, and shipping a second-life transfer flow for an average network takes a baseline of 10 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your passport and lifecycle rules into pre-audited WebAssembly binaries and provisions the shared passport ledger instantly.
