Self-Service Historical Time Series Analytics for Battery Manufacturing

Grayson TimeSeries analyzes one prepared CSV or Excel file from battery manufacturing history. Typical uploads include dry-room return and supply dew point with airlock state, rotor-speed command, and door-event timing; electrolyte-fill vacuum-cycle windows with chamber pressure, dosing command, delivered mass, cell format, and cycle group; and formation rows with channel, cell lot, recipe, maximum temperature, end voltage, charge capacity, ambient temperature, and maintenance markers.

Yes. With a prepared event file, Grayson can compare peak return dew point and recorded recovery duration across early and late door events while supply dew point remains comparable. Facilities teams can use that comparison to focus review on specific events, sensors, doors, dehumidification, airflow, operations, and maintenance records. Room dew point does not directly measure moisture in product materials.

Yes. Grayson can overlay prepared event-aligned cycle windows and compare chamber-pressure trajectories, dosing command, and delivered mass across early and late cycles or cycle groups. That surfaces a qualified list of cycles for reviewing records, valves, seals, pumps, sensors, recipes, and maintenance. A slower pump-down alone does not establish a leak or electrolyte wetting.

Yes. With one prepared row per channel and cycle, Grayson can group by lot and recipe, then compare feature trends such as maximum temperature, end voltage, and charge capacity across channels. That ranks which channel departs most consistently from the recent cross-channel pattern so formation and equipment teams can select channels, lots, and time periods for qualified review.

Convert high-rate traces and large continuous exports into selected windows or cycle-level features before upload, then combine them into one flat CSV or Excel file with units, step labels, event IDs, lot and recipe context, and maintenance markers. Direct historian access usually starts as a CSV or XLSX export; a managed AVEVA or historian connection needs IT.

Physical cause of vacuum or dehumidifier behavior, electrolyte wetting, electrochemical performance, cell safety, and product disposition require equipment knowledge, inspection, calibration, maintenance evidence, and approved methods. Grayson compares prepared environmental and equipment records; those quality and safety decisions remain with qualified review.
