Olivier BRIAT is a Professor at the University of Bordeaux, working within the IMS (Laboratoire de l'intégration, du matériau au système) research laboratory. He leads research in the RELIABILITY research group and is part of the RESS team. His work focuses on energy storage systems, particularly lithium-ion batteries and supercapacitors, with applications in electric and hybrid vehicles. His research interests span multiple areas of energy storage reliability and performance: Lithium-ion battery aging mechanisms and state-of-health estimation Supercapacitor performance degradation and reliability analysis Thermal effects on energy storage systems Electric vehicle powertrain integration Reliability testing methodologies for energy storage components Dr. BRIAT's publications show a strong focus on understanding and modeling the aging processes of energy storage systems. His work particularly emphasizes the impact of operational conditions (temperature, voltage, current profiles) on battery and supercapacitor lifetime. He has developed several methodologies for state-of-health estimation and remaining useful life prediction, with applications in both automotive and aerospace sectors. His research often involves close collaboration with industry partners including STMicroelectronics, Stellantis, GIS ALBATROS / Thales, NXP, CEA Leti, and SEQENS. His scientific contributions include numerous peer-reviewed publications in high-impact journals such as Applied Energy, IEEE Transactions on Industrial Electronics, and Microelectronics Reliability. He has also contributed to patent development in battery state-of-health evaluation methods and completed his HDR (Habilitation à Diriger des Recherches) on energy storage for electric and hybrid vehicles in 2017.
