One of our laboratory teams manually screens battery test results, sometimes after the data has been made available to the customer. Irregularities when conducting charge/discharge tests, such as testing equipment (cycler), unsecured connections, or misbehaving battery units due to internal faults, are common (25%~30%).
The customer is granted access to the test results through an online platform. Here, they have access to analytical capabilities where anomalies in battery test results can be screened for visually. The lab is subsequently informed where the customer typically requests re-testing of the unit(s) free of charge. Re-testing costs personnel time and uses revenue-generating cycler channels.
The aim of the project is to detect anomalies automatically in battery test results near real-time and inform personnel to halt the tests early. This can be achieved using statistical testing and machine learning.
Dataiku is a one-stop platform for applied data science and analytics methods and techniques. It helps with development and delivery/deployment speeds. Currently, five individuals are part of the team: Director of Data Science, Head of Data Analytics, Lead Data Scientist, Data Engineer, and Data Analyst(s).
To develop our solution, we used data preparation recipes, groupby, stack, filter/sample, python recipes, clustering for anomaly detection, statsmodels, and insights/dashboard for delivery.
The solution is an intermediator service that screens battery test results in seconds instead of hours. The statistical test runs on streaming data detecting signal irregularities. As soon as an issue is raised, a member of staff investigates, remediates the situation, and restarts the test if the battery unit is non-faulty. Otherwise, the unit is placed safely, waiting for its return to the customer.
