Contact-rich cell, module, and pack work — handled safely.
High-mix cell, module, and pack work is dexterous, safety-critical, and changes faster than fixed automation can be requalified.
The work is changing faster than you can staff it.
The dexterous, high-mix, contact-rich jobs are exactly the work classical automation was never built to hold — and the people who used to absorb it are getting harder to find.
Gigafactory ramps outpace hiring
Reshoring and IRA-backed gigafactory buildout is adding capacity faster than skilled labor can be hired and trained. Relling cells stand up in two weeks or less and carry qualified skills from HQ, putting working capacity on new lines as they come online.
Formats churn faster than tooling
Cell and pack formats change across programs and chemistries, and fixed tooling can't keep pace. A workcell that reconfigures in software absorbs format changes without rebuilds, holding throughput as cylindrical, prismatic, and pouch lines evolve.
Safety and traceability are non-negotiable
Live cells carry thermal, fire, and high-voltage risk, and every part needs serialized history. Force-controlled handling reduces damage events, and each step is logged and verifiable, supporting traceability auditors and customers require.
The contact-rich jobs on a battery & ev line.
One cell, reconfigured per part — not a new machine for every job on the floor.
Cell sorting & grading
Sort and bin cells by grade and voltage, handling each format without damage.
Stack & wind handling
Move stacks and jelly rolls into fixtures with controlled, low-force placement.
Tab welding prep
Position and align tabs and bus connections ahead of weld stations.
Module assembly
Seat cells into modules and drive fasteners to specified torque sequences.
Busbar placement
Place and align busbars across cell terminals before joining or fastening.
Thermal & adhesive dispense
Dispense thermal pads and adhesives to bead, coverage, and standoff spec.
One cell. Assembly, inspection, finishing.
Qualified off-site. Running in two weeks.
The slow, hard engineering happens on our floor — so the cell arrives tested and dialed in instead of tying up your team for months. A new part is a reconfiguration, not a rebuild.

Bring a Relling workcell to your floor.
We started Relling to help American manufacturers make more of what this country needs. We'll scope a single cell to your parts, qualify it before it ships, and stand behind it on your floor.
