EV Battery Cell Quality and Full Genealogy Traceability
Capture cell-level process and test data with full genealogy from cell to module to pack, so a suspect condition is contained to the exact units affected rather than an entire build period.
Solution Overview
The Challenge
Battery manufacturing produces quality escapes that only become apparent in the field, and without cell-level genealogy the only safe containment is every pack built in the suspect window, which can be a hundred times the number actually affected.
- 1Containment scoped to entire build windows because cell-level genealogy does not exist
- 2Process data captured per batch, so field failures cannot be correlated to causal parameters
- 3Cell to module to pack relationships not retained, breaking the traceability chain
Our Approach
CloudGate captures process and test data at cell level through every station, maintaining parent-child genealogy from raw material lot through cell, module and pack.
- Cell-level process and test capture at every station rather than batch-level sampling
- Full genealogy from material lot through cell, module and pack, retained end to end
- Process parameter correlation against end-of-line test and field performance

Vehicle Quality Early Warning from Warranty and Telemetry
Detect emerging quality issues weeks earlier by combining warranty claims, dealer narratives and vehicle telemetry, and scope the affected population precisely enough to contain it.
Production Scheduling and Sequencing Optimization
Generate feasible production schedules against real constraints in minutes, and let planners compare objectives before committing rather than defending a plan built in a spreadsheet.
Manufacturing Energy and Emissions Management
Measure energy and emissions per line, per shift and per unit produced, so reduction targets are pursued against evidence rather than against the monthly utility invoice.
