EV manufacturing, fully connected

From cell incoming inspection to pack EOL test — one platform for traceability, change control, and real-time line visibility across battery, motor, and final assembly.

Key Challenges

Three problems every EV manufacturer hits

These are not theoretical. They come from production floor audits and post-recall root cause analyses we have conducted with our automotive customers.

Challenge

No cell-to-pack traceability

Individual cell serial numbers, formation data, and impedance measurements are lost between incoming inspection, module assembly, and pack integration. When a field recall hits, you cannot trace which packs contain affected cells.

How DFI Solves It

DFI Digital Twin captures cell-level genealogy at every station. Scan a pack serial and retrieve the full tree: cells, module torque values, BMS firmware version, and EOL test results.

Challenge

Engineering changes take weeks

A BMS firmware update requires email chains between R&D, manufacturing engineering, quality, and the supplier. By the time the ECN is signed, three production lots have shipped on the old revision.

How DFI Solves It

DFI PLM routes ECO/ECN workflows in parallel to all stakeholders, auto-populates affected BOMs, and blocks production release until digital signatures are complete. Average ECN cycle time drops from 18 days to 3.

PLMChange Control

Challenge

Multi-tier supplier BOM drift

Tier-1 suppliers substitute components without formal notification. The manufacturing BOM diverges from the engineering BOM. Quality finds out only after AOI flags an unknown part number.

How DFI Solves It

DFI PLM maintains linked Engineering, Manufacturing, and Service BOM views. Supplier portal submissions trigger automatic where-used impact analysis and revision comparison diffs.

Battery Line Coverage

Every station, every data point

The digital twin mirrors your physical battery line station-by-station. Each stage captures process parameters, quality metrics, and genealogy data in real time.

Platform modules used

The automotive solution draws from multiple DFI modules. Each is available standalone or as part of the full platform.

“Before DFI, a single recall investigation took our quality team two weeks. Now we pull the full cell-to-pack genealogy in under two minutes.”
