Free CMMS and OEE Tracker for Battery Manufacturing
Track the coating web breaks, calender roll changes, and dry-room stops that quietly bleed yield on a cell line. Free, on one line, starting today.
The short answer
- Start free today: log a shift on your coater, calender, stacking cell, or formation bank in the free OEE tracker in about 2 minutes, no account.
- What it catches: coating and calendering micro-stops, dry-room dew-point excursions, formation and aging holds, and expensive electrode scrap, all ranked in a downtime Pareto.
- Its honest limit: manual entry, one plant on one device, no PLC or MES link, and you investigate each web break and seal fault and raise every work order yourself.
- When to graduate: once high-throughput micro-stops outpace manual logging, Fabrico reads OEE off the PLC, finds micro-stop true-cause on video, and auto-routes the work order.
Battery and EV cell lines run at high web speeds with brutal scrap economics, so a coating streak, a calender roll change, a slitting burr, or a dry-room dew-point excursion rarely trips a full line stop. It just quietly eats yield and cycle time until a shift total looks wrong and nobody can name the cause. Most gigafactory teams already count cells and track scrap, but the sub-minute stops between the coater, the stacker, and the formation racks stay invisible until someone logs them by hand. Start with the free OEE tracker, learn what OEE actually measures, and see why downtime tracking is the first move.
The free OEE tracker lets a line owner log a shift in about 2 minutes, get instant OEE with availability, performance, and quality, and see a downtime Pareto that ranks coating, calendering, tab-weld, and formation losses against a world-class 85% benchmark. It also includes a light work-order board and a preventive-maintenance schedule, enough to run one electrode or assembly line for real, with no account and no signup.
This is the honest, best free way to build the loss picture that justifies an automated rollout across a cell plant. When high-throughput micro-stops on a coater or formation channel move faster than any operator can type, Fabrico is the platform to graduate to: it reads OEE off your PLCs, uses computer vision to find the true cause of each micro-stop with video evidence, and auto-routes the work order the moment a line drifts. See also what a stop really costs and how free OEE software fits your stack.
What you get, free
2-minute shift logging
Log a shift by hand in about 2 minutes: run time, stops, scrap and rework counts. No PLC connection needed to start on a coating line, calender, stacking cell, or formation bank.
Instant OEE plus availability, performance, quality
See OEE and its three sub-metrics the moment you save a shift, so a bad day reads clearly as a dry-room availability problem, a web-speed performance problem, or an electrode-quality problem.
Downtime Pareto against a world-class 85% benchmark
Rank your real losses, coating streaks, roll changes, splice stops, tab-weld faults, and formation holds, against a world-class 85% OEE benchmark, so you know which stop is bleeding the most line rate this week.
Work-order board and PM schedule
Raise a work order the moment a coater die, slitter blade, or dry-room desiccant wheel starts recurring, and keep a preventive-maintenance schedule for the assets you track, with a per-machine breakdown.
Asset register, CSV/JSON export, and backup/restore
Register your mixers, coaters, calenders, notchers, and formation cyclers, export everything to CSV or JSON when you need it elsewhere, and back up or restore the whole dataset from a file.
Printable report, shareable scorecard, installable PWA
Print a PDF shift report, share a read-only scorecard with a plant manager without opening a spreadsheet, and install the tracker as a PWA on a dry-room or shop-floor tablet.
Log one shift and the free tracker shows your OEE, your loss Pareto and how you compare to world-class. Add work orders and preventive-maintenance reminders in the same place.
Where free stops, and Fabrico begins
The free tracker is built for getting started fast and for one plant on one device. When a site gets serious about its losses, the manual steps start to cost more than they save. This is exactly where Fabrico takes over.
| Capability | Free OEE Lab tracker | Fabrico |
|---|---|---|
| Data capture | Log each shift by hand in about 2 minutes on a coating, calendering, stacking, or formation line, data stays in your browser. | Reads OEE automatically off your line PLCs, no manual entry across high-speed electrode and assembly stations. |
| Micro-stop cause | You investigate sub-minute web breaks, coating streaks, splice stops, and tab-weld faults yourself and note the reason. | Computer vision identifies the true cause of each micro-stop, with video evidence, across coater, slitter, and assembly cells. |
| Loss-to-fix loop | You spot the pattern, then raise the work order yourself on the board. | A detected loss becomes an auto-routed work order, assigned the moment a line drifts, closing the PLC-to-work-order loop. |
| Scope and multi-site | One plant on one device and browser, best for a single coating or assembly line or one shift. | Plant-wide and multi-site from one central view, across electrode, cell assembly, and formation and aging. |
| Integrations | Standalone, run it on its own, export data when you need it elsewhere. | Integrates with PLCs, MES, and ERP so cell-line OEE flows with your existing stack. |
| Access and roles | People and roles live on that one device, so a shift lead and operators log in locally. | SSO, plant-wide roles, and a full audit trail of who changed what across sites. |
| Data residency | Your data lives in your own browser storage on your device. | EU-built with EU data residency, outside the reach of the US CLOUD Act. |
| Reporting | Instant OEE, A/P/Q, a downtime Pareto, per-machine breakdown, a printable PDF, and CSV/JSON export you run yourself. | Live plant-wide dashboards plus scheduled reports delivered automatically, with an audit trail that supports audit-readiness (ISO 27001, 20000-1, 9001). |
| Scrap and yield sensitivity | Log scrap and rework counts per shift and rank them in the Pareto, you connect each defect to a root cause by hand. | Ties a coating or seal defect to the exact micro-stop that caused it on video, so expensive electrode scrap gets traced to a fixable event. |
Frequently asked questions
How do I track coating and calendering micro-stops in the free tracker?
Log each shift in the free OEE tracker and record every stop under a minute, web breaks, splice stops, roll changes, and coating streaks, separately from planned downtime. After a week the downtime Pareto shows whether your coater, calender, or slitter is bleeding the most line rate, which is the loss picture a line owner needs before asking for budget. The honest limit is that you are the one watching the line and typing the reason. Fabrico reads web speed off the PLC and flags the true cause automatically, with video evidence, the moment a station drifts.
Can the free tool help with dry-room reliability?
Yes, within its limits. Register your desiccant wheels, HVAC units, and dew-point sensors in the asset register, put them on the preventive-maintenance schedule, and raise a work order whenever a dew-point excursion forces a stop. You log the events by hand and read the Pareto to see how often the dry room is your constraint. It does not connect to your building-management system or capture excursions automatically, which is where a PLC-connected platform like Fabrico takes over.
How do I see if formation and aging is my bottleneck?
Log formation and aging as their own line in the tracker and record every hold, channel fault, or cycler stop. Because these steps have long cycle times and a large footprint, they often cap plant throughput even when electrode and assembly run clean. The per-machine breakdown and Pareto will show whether formation channels or aging racks are your true constraint, so you can size the problem before investing in more capacity.
Is the OEE Lab tracker really free for a cell plant, or a trial?
It is free with no signup and no expiry, not a limited trial. Open oee-tracker.html, start logging a shift, and your data stays in your browser on that device. There is no seat cap counting down and no card required. The tradeoff is scope: one plant on one device, all manual entry rather than PLC-connected, which is where Fabrico takes over once you scale beyond one line.
When do I need more than the free tool?
When your losses are high-throughput micro-stops spread across a coater, slitter, stacking, and formation, manual shift logging stops keeping up and you lose the true cause. That is the point to move to Fabrico, which reads OEE off the PLC plant-wide, uses computer vision to pin the true cause of each micro-stop with video evidence, and closes the loop by auto-routing the work order. It is EU-built with EU data residency and supports audit-readiness for your quality evidence. Book a Fabrico demo to see it on your own line.
We already run a CMMS for work orders. Do we still need this?
For the OEE side specifically, it helps. A general CMMS focuses on running work orders and PM schedules, so its core job is that loop rather than calculating OEE, availability, performance, and quality from a logged shift or ranking a downtime Pareto against a benchmark. Use the free OEE tracker alongside your existing CMMS to get the loss visibility, then decide whether you want two tools or a single platform like Fabrico that does automatic OEE capture and the work-order loop together.
When free is not enough, Fabrico is the upgrade
Battery and EV cell losses are dominated by high-throughput micro-stops on the coater, calender, and slitter and by long formation and aging holds, spread across lines where manual shift logging stops scaling. Fabrico reads OEE off your line PLCs plant-wide and multi-site, uses computer vision to identify the true cause of each micro-stop with video evidence, and closes the loop by auto-routing a work order the moment a line drifts, so a recurring web break or seal fault gets assigned without an engineer writing it up. It is EU-built with EU data residency, outside the reach of the US CLOUD Act, and it holds ISO 27001, 20000-1, and 9001 certifications, so it supports audit-readiness for your quality evidence.
