In Europe, there was no supplier that could provide the complete system technology for the production of vehicle batteries from a single source. Dürr, iTAC and other partners have changed that. They offer manufacturers of lithium-ion batteries production and digitalization technology from a single source – across the entire value chain. iTAC Software AG handles the digitalization part with its MOM system (Manufacturing Operations Management).
According to the German Federal Motor Transport Authority, around 524,200 all-electric cars were newly registered in 2023 – an increase of 11.4% compared to the previous year. As demand increases, so do the requirements for battery production. Production capacities must be able to be expanded quickly and manufacturing efficiency must be continuously improved in order to keep pace with demand and reduce production costs. At the same time, strict quality controls and safety measures must be guaranteed to ensure that the batteries are safe to use.
Last year, Dürr, GROB and Manz formed the first European cooperation to emerge in the field of production technology for lithium-ion batteries – with the aim of establishing themselves as suppliers of complete battery production systems. Together with other partners, they offer the entire plant and digitalization technology for the production of vehicle batteries from a European source. The value stream covers all stages from electrode production to battery pack assembly.
End-to-end digitalization for battery production
In this context, iTAC is the expert for the digitalization of processes. The iTAC.MOM.Suite production management system from iTAC and Dürr can map all processes end-to-end. It enables the mapping, control and planning of the entire production process as well as traceability.
Traceability is one of the most important building blocks here. “In the demanding production of battery cells, materials are used that are difficult to process and sometimes very dangerous. To minimize risks, avoid errors and optimize processes, end-to-end traceability and quality analysis are essential. In this way, quality and performance characteristics as well as all standards and other requirements can be met,” explains Martin Heinz, board member of iTAC Software AG.
In addition to the traceability functionality, the iTAC.MOM.Suite offers tools such as the iTAC.BI.Service and Quality Management. These provide analysis and reporting functions for all product-related quality data. This allows the quality of the electrodes to be evaluated and analyzed throughout the entire process. “Defects, such as holes that can occur in the coating production process, are documented, can be traced and thus sorted out in later process steps. Transparency in production is possible with both business intelligence and real-time dashboarding. This makes optimization potential visible,” says Martin Heinz.
The use of data analytics tools ensures that changes and anomalies are detected at an early stage, thus creating the basis for predictive control of production processes (predictive quality) in battery production. In addition to the lithium-ion battery cell, other cell types can also be mapped in the iTAC solution.
At the same time, it is important to ensure a high level of efficiency through sophisticated production planning in order to meet the continuously increasing demand. In combination with the Advanced Planning and Scheduling System (APS) from DUALIS integrated in the iTAC.MOM.Suite, optimized production planning based on actual and limited capacities is possible. This creates a holistic planning approach that takes all resources (machines, processes, tools, materials, personnel) into account and ensures their optimal use.
Martin Heinz explains: “In combination with the system technology, we are working with Dürr and the other partners to enable manufacturing companies to increase their production capacities for batteries quickly and safely. They don’t have to spend time searching for several partners who ultimately offer isolated solutions, which can be at the risk of process efficiency and cost-effectiveness.”
