Dans le cadre de la 41ème édition des Benelux Meetings on Systems and Control (5-7 juillet, Bruxelles), le Professeur David Howey (Université d’Oxford) a donné une conférence intitulée « Data-driven battery health diagnosis in real-world applications ». David Howey est Professeur d’Engineering Science à l’Université d’Oxford et Tutorial Fellow à St Hilda’s College. Avec Michel Kinnaert (Department of control engineering and system analysis, ULB), il dirige le projet de recherche « Identification d’un modèle électrochimique de batterie lithium-ion incluant le vieillissement pour la conception d’un jumeau numérique », l’un des neufs projets de collaboration soutenus par la Fondation pour la période 2022-2024.

Accurate diagnostics and prognostics of battery health improves overall system performance. This allows industry to unlock value by detecting faults and improving maintenance and logistics, extending operational range, and understanding asset depreciation. However, battery aging is complex and caused by many interacting factors. Two key questions arise: first, how to handle modelling challenges, including parameter variability and nonlinearities, in methods for online estimation of state of health. Second, how to develop validated predictions of future health, where key issues include coping with variable usage scenarios, and cell-to-cell behavioural differences. This talk will discuss recent approaches to tackle some of these exciting topics, particularly focusing on diagnostics from field data, including the combining of non-parametric and parametric models to allow flexibility in model fitting from data, whilst retaining the benefits of equivalent circuit and physical models.
