BMW Group and University of Zagreb: Advances in battery cell production using artificial intelligence

+++ Pilot project at Battery Cell Competence Centre (BCCC) +++ Reduced testing effort and savings in raw materials, costs and time +++ Pioneering integration of theory and practice +++

Munich/Zagreb. The BMW Group and the Croatian University of Zagreb’s Regional Centre of Excellence for Robotic Technology (CRTA) continue to advance joint research in battery cell production. The “Insight” research project will develop and implement practical AI models to optimise battery cell production at the BMW Group. The research project covers the entire battery cell value chain: from electrode production to end-of-line testing and in-house developed direct recycling.

How the research project saves raw materials, costs and time

At the Battery Cell Competence Centre (BCCC) in Munich, the BMW Group is developing battery cells for future generations of high-voltage batteries. As part of this process, numerous test series are conducted, which by their very nature require significant time and material investment. At the same time, these tests tie up manufacturing equipment and laboratory capacity. This is where the “Insight” research project comes in: Its artificial intelligence network uses existing test data, as well as real-time data from ongoing production, to accurately predict battery cell process parameters and performance data. As a result, the duration and number of test series can be significantly reduced, while maintaining or improving quality. In this way, the newly developed AI systems reduce the material and time required in individual process steps by more than 50 percent.

Other cell production use cases

The research project’s prediction models not only reduce the number of test series but also support final approval of battery cells. Following initial charging at the end of production, the cells must be…
