Project Objective and Description

Current battery development is limited by a lack of methodological and data support early in the development process, resulting in costly and time-consuming physical verification and validation (V&V) activities. Therefore, the goal is to advance front-loading and continuous V&V to significantly optimize battery design, cost, and time-to-market. To this end, innovative physical and data-driven simulation models are being developed with respect to battery subsystem performance, lifetime, reliability, and safety. To ensure the applicability of these models and a high level of reliability, they will be complemented by new technologies to measure model parameters in real time and upscaling methods to scale cell models to battery system models. The models and measurement data will be synthesized into digital twins that can be used in V&V.

To optimize frontloading, testing of these digital twins will be merged with physical testing in a novel hybrid design verification and validation plan (hybrid DVP method). Based on systems engineering principles, processes and methods currently used by AccCellBaT consortium members will be combined and optimized with the hybrid DVP to ultimately create a process and method manual applicable to future battery development.

CONWEAVER, as part of the AccCellBaT project, is exploring how Linked Data approaches can provide contextual data for models and digital twins to significantly accelerate product development processes, compared to the previous disjointed and heterogeneous data in traditional PLM system approaches that prevent cross-discipline collaboration and data connectivity.

Seamless end-to-end collaboration between disciplines, domains and companies must also be established within AccCellBaT. Participants in all phases of the process must be able to request data and information from other participants and incorporate it into their tasks. The mechanical, electrical and software areas must work together with new methods and processes to enable the subsequent process stages (integration, production planning, production and operation) to use this data and knowledge.

"Providing cross-domain, cross-discipline, and cross-enterprise data that delivers contextualized information across the lifecycle at the right time to the right stakeholders at every stage of the process with the click of a mouse - that's the gamechanger to streamline information gathering to enable frontloading and shorter time to market."
