Trustworthy Virtual Measurements in Battery Manufacturing

Abstract

The growing demand for electric cars necessitates an increase in battery production efficiency and cost-effectiveness. Through a reduction of the joint testing efforts an increase of productivity can be accomplished. To achieve the reduction, remain on a high level of quality standards and increase the informational content about current production the use of virtual measurements is examined. Ensuring the trustworthiness of virtual measurements is crucial for informed decision making, necessitating validation. This paper explores the requirements and challenges in battery manufacturing for implementing trustworthy virtual measurements. Two central requirements are identified to enable virtual measurements. Firstly, a traceability system based on the production meta-model is needed to track process parameters and quality characteristics. Secondly, a framework is proposed to facilitate reliable virtual measurements. The primary challenge for virtual measurement in battery manufacturing systems from the complexity of the process chain and products. It is crucial to assess how virtual measurements perform across various processes and to evaluate their transferability to different process parameters and products.
