EV Battery Traceability & Battery Passport System

An EV battery traceability system has to hold together at cell level, because a warranty claim or a field failure is never really about the pack as a whole. We build cell-to-pack genealogy into your assembly line: scanners at incoming, module and pack build records, BMS pairing, tester data and a digital passport at despatch.

Cell to Pack Genealogy

Every cell serial linked to its module, its pack, its BMS and the vehicle it ships to.

Tester and BMS Data Linked

End-of-line test results and BMS firmware versions recorded against the pack serial, never filed separately.

Passport Ready for Export

Data structured for the EU Battery Regulation digital battery passport before you start exporting packs.

Warranty & Recall Control

Build, test and field history remain connected to the same pack serial for faster investigation.

Our EV Battery Traceability & Battery Passport System

Incoming cell capture, module and pack genealogy, end-of-line and BMS records, and passport handover - engineered into your assembly line and integrated with your ERP.

1. Incoming Cell & Component Capture
Traceability starts at the goods-inward dock, not at pack assembly. We capture cell serials and supplier lot codes so a defective cell batch can be blocked before it ever reaches the line.

Key Capabilities:

Cell serial and DataMatrix capture at goods-inward stations
Supplier lot, chemistry, capacity grade and test certificate linkage
Busbar, BMS board, connector and enclosure component records
Quarantine and block rules applied automatically to suspect cell lots
2. Module & Pack Build Genealogy
Each module records the exact cells inside it, and each pack records its modules. We build that parent-child structure at the station, so it is never reconstructed from build sheets later.

Key Capabilities:

Cell-to-module and module-to-pack linking captured at each station
Welding, bonding and torque parameters recorded against the serial
Operator, station, shift and fixture identity on every build event
Rework and cell replacement tracked without breaking genealogy
3. End-of-Line Test & BMS Pairing
A pack leaves with a BMS, a firmware version and a set of test results, and all three must stay attached to its serial. We integrate the testers and the flashing station directly.

Key Capabilities:

End-of-line tester integration for capacity, IR and HiPot results
BMS serial pairing and firmware version recorded at flashing
Insulation resistance, leak and thermal results held per pack serial
Pass, fail and rework routing enforced before despatch labelling
4. Battery Passport, Warranty & End-of-Life
The same record serves your warranty team, the regulator and the recycler. We structure it once and expose the relevant slice to each, including a QR-linked passport a fleet operator or dismantler can read.

Key Capabilities:

QR-linked pack passport carrying chemistry, capacity and origin data
State-of-health and warranty claim history held against pack serial
EPR handover records under the Battery Waste Management Rules
Second-life grading records and dismantler handover documentation

Key Performance Indicators

Measures agreed with your quality head, battery pack plant manager and product engineering lead before the pilot, then reported from the line dashboard.

Cell Serial Capture Rate
Share of cells entering the line with a captured, verified serial linked to a supplier lot.
Target: 100% of cells
How we get there: Achieved with scanner positioning trials and a station interlock that blocks unread cells.
Pack Genealogy Completeness
Share of despatched packs holding a complete cell, module, BMS and test record.
Target: >99.5%
How we get there: Enforced by station sequencing that stops a pack progressing with a missing record.
Suspect Lot Containment Time
Time taken to list every pack containing cells from a suspect supplier lot.
Target: Under five minutes
How we get there: Indexed genealogy replaces reconstruction from build sheets and despatch registers.
Warranty Claim Validation Time
Time to confirm build history, test results and field data for a returned pack.
Target: Same working day
How we get there: All three data sets sit against one pack serial instead of three separate systems.

How We Deliver

A staged rollout that proves capture works on one pack line before the rest follow.

Step 1: Requirement Study & Line Walkthrough
We map every station from goods-inward to despatch, record your BOM structure and test sequence, and confirm which export markets apply.
Step 2: Solution Design & Station Layout
Scanner positions, tester interfaces, interlocks and the data model are signed off, including how rework and cell replacement will be handled.
Step 3: Pilot on One Pack Line
One line runs end to end against agreed acceptance criteria, so capture rates and genealogy completeness are proven on your own pack design.
Step 4: Rollout, Passport Setup & Support
Remaining lines are commissioned, passport and EPR reporting views are configured, and the system moves into an AMC with defined response times.

Why Choose Our EV Battery Traceability & Battery Passport System?

Why Indian pack makers choose an engineered traceability system rather than a generic MES module bolted onto the line.

Built Around Your Pack Design
Cell count, module topology, welding method and test sequence differ with every pack. The data model is built to yours, not to a fixed template.
Testers and Tools Integrated
EOL testers, welders and BMS flashing tools are integrated at protocol level, so results are captured as facts rather than retyped by an operator.
Export Regulation Ready
Battery Waste Management Rules obligations under CPCB and EU Battery Regulation passport requirements are designed in, so an export order does not trigger a rebuild.
One Accountable Team
Scanners, interlocks, integration, software and support come from a single engineering team, so a capture failure at station four has exactly one owner.

Frequently Asked Questions (FAQs)

1. What is an EV battery traceability system?

It is a system that records the complete build and service history of a battery at cell level. Each cell serial is captured at goods-inward and linked to the module it goes into, the pack that module joins, the BMS paired with it and the end-of-line test results. That record follows the pack through warranty, state-of-health monitoring and recycling, so any failure traces back to a specific cell lot or shift.

2. Is this a licensed product or a custom-built system?

Custom-built. We are a solution development and systems integration company rather than a SaaS vendor. The project starts with a requirement study of your pack architecture, station layout and test sequence, and the system is engineered to that specification.

3. Do you supply the scanners and station hardware too?

Yes. Fixed-mount and handheld scanners, station interlocks, label printers and applicators are scoped, supplied, installed and integrated. We take responsibility for capture rate at the station, not only the software.

4. How does this relate to AIS-156 safety compliance?

AIS-156 sets the safety requirements Indian EV battery packs are tested and certified against. Traceability does not replace certification, but it supplies the evidence behind it: the cell lot, welding parameters, insulation resistance result and thermal check belonging to each pack.

5. What is a digital battery passport, and do we need one?

The EU Battery Regulation requires a digital battery passport carrying chemistry, capacity, carbon footprint, origin and end-of-life data, accessible through a QR code on the pack. Indian makers exporting to Europe will need it, and we generate that view from records you already capture.

6. Can you integrate with our ERP and existing line systems?

Yes. We integrate with SAP, Oracle, Navision and Tally for batch and despatch data, and with MES, welders, EOL testers and BMS flashing tools at the line. Where a tester exposes only a log file, we build that interface.

7. Can the system run on-premise rather than on cloud?

Yes. On-premise, private cloud and hybrid deployments are all supported. Many pack makers keep build genealogy inside the plant while exposing only the passport and warranty views externally, and the line keeps capturing when connectivity drops.

8. How does the system support recycling and second-life handover?

The Battery Waste Management Rules notified by CPCB place extended producer responsibility obligations on producers. The system holds pack chemistry, capacity and state-of-health data, records handover to a registered recycler, and produces the documentation EPR reporting requires.

9. How long does implementation take?

A single pack line is typically live within eight to fourteen weeks of requirement sign-off, depending on how many testers and tools need integration and how quickly scanner hardware arrives. Further lines follow in phases.

10. What support is provided after go-live?

Support runs under an agreed arrangement covering defined response times by severity, preventive maintenance of scanners and station hardware, integration troubleshooting when a tester or ERP interface changes, and enhancement requests.
