The recent “BMS Alliance Webinar: Data Access and Harmonization” brought together the four sister projects of HORIZON-CL5-2022-D2-01-09, focusing on physics and data-based battery management for optimized battery utilization.

The goal of the BMS Alliance’s webinar series is to build bridges between the projects, exchange information, tackle common challenges and join forces to find solutions. On the topic of this second webinar – the usage of data in the four sister projects – the bridges discussed during the meeting were, first and foremost, “linguistic”: the more partners and related projects speak the same language when it comes to data, the more fluid, smooth, and mutually understandable the circle of ideas, codes, and projects becomes.

Throughout the webinar, Stefan Waldhor (BATMAX), Aurelien Hascoat (ENERGETIC), Vira Vadaviya (NEXTBMS), and Bernard Lutzer (NEMO), discussed good practices for data accessibility and harmonization.

The partners shared their intra-consortium data standardization practices but also raised broader issues. In particular, Bernhard Lutzer from NEMO pointed out the lack of a standardized Electrochemical Impedance Spectroscopy (EIS) ontology, and the need to develop a common language: “A key point in data harmonization is to have people in your organisation who understand both the world of the data providers and those who manage and analyze data, as this bridge between the two worlds is essential for seamless communication and effective collaboration.”

This way, an immediate understanding of the “ontological lexicon” within the EIS projects (such as the four discussed in this webinar) could be achieved.
