The project BATTwin : Flexible and scalable digital-twin platform for enhanced production efficiency and yield in battery cell production lines made a significant impact at the Upcell Alliance event. Hosted by the Conservatoire National des Arts et Métiers (CNAM) in Paris on November 14–15, 2024, the event brought together 160 key stakeholders in battery manufacturing, technology innovation and academia to discuss advancements in the sector and facilitate networking. Representing BATTwin were Prof. Marcello Colledani (Project Coordinator), Prof. Nada Mimouni (cybersecurity task lead), and PhD Donia Marzougui from Verkor, a French gigafactory and use-case provider in the project.

Highlighting Zero-Defect Manufacturing for Gigafactories

The event featured a detailed and engaging presentation on BATTwin’s objectives and progress. Specifically, the project aims to revolutionize gigafactory production efficiency and battery cell yield through the adoption of a zero-defect manufacturing (ZDM) approach. In addition to explaining the challenges of modern battery cell production, the presentation demonstrated how BATTwin’s digital twin technology is poised to overcome these obstacles effectively.

Additionally, the presentation outlined several essential components of BATTwin’s work:

• Formal Process Representation: Leveraging the IDEF0 formalism, structured graphs of end-user process chains were developed, providing a clear and systematic visualization of operational flows.
• Defect Mapping: A detailed analysis was conducted to map defect types and their root causes, delivering critical insights into vulnerabilities across the production chain.
• Digital Twin Development: The BATTwin consortium systematically identified and consolidated requirements for developing digital twins at both the process and system levels, ensuring comprehensive and resilient solutions.
• Key Performance Indicators (KPIs): Targeted KPIs were defined to track and measure significant improvements in process efficiency and overall system performance.

Updates and Industry Engagement

The presentation included updates on ongoing activities, with special emphasis on the upcoming Battery Manufacturing Industry Winter School. Scheduled to take place from March 24–27, 2025, and spearheaded by Verkor with support from BATTwin, Upcell Alliance and Ecole de la Batterie, among others, the program will focus on advancing training on industry-related topics.

Tackling Cybersecurity in Battery Production

Prof. Nada Mimouni delivered a compelling segment on the rising cybersecurity threats facing the battery cell manufacturing sector. Her talk emphasized the importance of leveraging ontologies and knowledge graphs to create robust security frameworks. This innovative approach is expected to strengthen the resilience of manufacturing systems against cyber threats.

Driving Innovation in Battery Manufacturing

We are proud to say, the Upcell Alliance event underscored the growing collaboration between academia, industry, and innovation projects like BATTwin to address the pressing challenges of battery production. By focusing on ZDM, digital twins, and cybersecurity, BATTwin is paving the way for more efficient, sustainable, and secure gigafactory operations.
