Interview with Professor Konstantinos Tserpes from the University of Patras

What is the role of University of Patras in the TEMPEST Project?

In TEMPEST, University of Patras is working on the development of a digital twin of the composite battery housing which will be used for the design of the housing and the evaluation of innovative technologies such as the application of a protective layer using the cold spray technology and the use of a debondable on demand adhesive for assembling the housing parts. The main objective is to reduce the cost of future batteries for small and large mobile applications by significantly reducing the development time and cost of the design phase. To feed the digital twin and validate the proposed designs, University of Patras will conduct static and dynamic mechanical tests at different scales, from the coupon scale to the housing scale.  Moreover, University of Patras is coordinating the Education, Training, and Knowledge transfer efforts in the project.

What methodologies and protocols will the University of Patras employ to define material specifications and gather material properties for input into modeling processes?

The material specifications are defined in collaboration with the battery manufacturers, namely, Albio Technologies and Avesta Battery & Energy Engineering, and the technology developers, namely, Fraunhofer ICT and RESCOLL that participate in TEMPEST. The main driver for the material specification definition is the fulfillment of the technical objectives of the demonstrators. The material properties required by the models are determined through mechanical, electrical, and thermal tests that are conducted according to international material testing standards (e.g. ASTM and ISO) and battery testing standards.
