Arnaud Devie

Arnaud Devie (Ph.D., Electrical Engineering, University of Lyon, France) received his electrical engineering degree from INSA Lyon, France, with a major in semiconductor technology. He then worked toward a M.Sc. degree in electrical engineering while modeling and developing silicon carbide integrated circuits at Ampere Lab. Dr. Devie later joined the University of Lyon for a Ph.D. in electrical engineering in collaboration with the French Institute of Science and Technology for Transport, Development and Networks (IFSTTAR), where he undertook the characterization of lithium-ion batteries usage in EV and HEV applications. As part of his thesis work, Dr. Devie collected and analyzed more than 10,000 miles of data from 6 electrified vehicles and designed K-means clustering and Markov chain modeling techniques to generate synthetic battery duty profiles for testing battery degradation under specific usage patterns. Dr. Devie joined the Hawaii Natural Energy Institute at the University of Hawaii at Manoa in 2013 to work on lithium-ion battery degradation diagnosis with Dr. Matthieu Dubarry and Dr. Bor Yann Liaw. His current work focuses on cell design, diagnosis of abuse and consistency of degradation inside a batch of batteries.
