BPAN issuance and QR labels
21-character Battery Pack Aadhaar Numbers composed and validated to the draft specification, with a QR code for each pack.
Battery lifecycle passport
PackPass: a lifecycle passport for every battery pack.
PackPass issues a Battery Pack Aadhaar Number for each pack, keeps its record from manufacture to recycling, and exports the same record as an EU Battery Passport, so battery makers keep one source of truth for both regimes.
Status: MVP built
The problem
Battery traceability is becoming a legal requirement in two major markets at once. India’s Ministry of Road Transport and Highways has proposed a Battery Pack Aadhaar Number (BPAN) for every pack in draft guidelines dated 30 December 2025, and the EU Battery Regulation makes a digital battery passport mandatory for electric vehicle, light means of transport and larger industrial batteries from 18 February 2027. The data behind both, from chemistry and capacity to origin, certificates and state of health, is scattered across factory systems, supplier documents and the battery management system.
How we approach it
PackPass keeps one canonical record per pack and derives everything else from it. Identifiers are composed to the BPAN layout in the draft, every lifecycle event is written to a hash-chained ledger, battery management system telemetry is summarised into the figures a passport needs, and certificates are read into structured fields. Only cryptographic proofs are anchored to a blockchain; the battery data itself never is.
Capabilities
What it does.
Canonical pack record
Static data such as chemistry, capacity, voltage and origin, and dynamic data, held in one schema-validated record.
Tamper-evident lifecycle ledger
Every change to a pack produces exactly one hash-chained event, from manufacture through second life and recycling.
BMS telemetry ingestion
CAN logs decoded and summarised into the telemetry a battery passport records.
Certificate extraction
Battery test and certification documents read into structured fields with AI document extraction.
EU Battery Passport export
The same record exported as EU Battery Passport JSON and validated against a schema.
Who it is for
Built for.
EV and battery pack manufacturers
Meeting BPAN labelling in India and battery passport duties for EU exports from one system.
Battery importers
Holding the pack-level data regulators and customers ask for, independent of each supplier’s tooling.
Fleet and second-life operators
Carrying a verifiable history with each pack as it changes hands.
Recyclers
Receiving end-of-life packs with the chemistry and history recycling depends on.

FAQ
Questions we get asked.
A 21-character identifier proposed for battery packs in India, especially electric vehicle batteries, in draft guidelines from the Ministry of Road Transport and Highways dated 30 December 2025. It encodes the manufacturer, key battery characteristics and a pack-level identity. The guidelines are still a draft, to be implemented through the Automotive Industry Standards process.
Under the EU Battery Regulation (EU) 2023/1542, from 18 February 2027 for electric vehicle batteries, light means of transport batteries and industrial batteries above 2 kWh placed on the EU market.
No. Pack data stays in PackPass. Only Merkle roots, short cryptographic proofs of the ledger, are anchored, so the record can be shown to be unaltered without publishing the data.
A working MVP issues BPANs, keeps the lifecycle ledger, ingests telemetry and exports EU passport JSON. The government BPAN portal is not live yet, so PackPass produces validated batch export files in the meantime. We are looking for battery makers to pilot it.
