Ahmad Pesaran is the chief energy storage engineer for NREL’s Center for Integrated Mobility Sciences. At NREL since 1983, his work has spanned various technical arenas, including automotive batteries, buildings, ocean-thermal energy conversion, and advanced air conditioning. He has co-authored more than 150 journal articles and technical papers on energy storage and electric-drive vehicles.
Currently he supports the U.S. Department of Energy (DOE) Vehicle Technologies Office (VTO) with battery recycling, battery processing and manufacturing, and low-cobalt cathode development projects. He also serves on the electrochemical energy storage technical team and workgroups of the U.S. DRIVE (Driving Research and Innovation for Vehicle efficiency and Energy sustainability) program.
He started working on batteries, ultracapacitors, hybrid electric, battery electric, and fuel cell vehicles in 1995, collaborating with car and battery manufacturers on battery thermal analysis and battery thermal management issues.
Until 2017, he was the manager of NREL’s energy storage research team working on high energy anodes, electrode coatings, battery thermal analysis and evaluation, lithium-ion battery safety modeling and evaluation, three-dimensional electrochemical-thermal modeling, techno-economic analysis of batteries for electric vehicles, and post-vehicle battery second use. From 2010 to 2016, he was the technical lead for DOE’s Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT) program.
From 2016 to 2018, he was on detail in Washington, D.C. as a technical advisor to the VTO Battery R&D Program, supporting extreme fast charging of electric vehicle batteries, battery processing and manufacturing projects, and battery recycling.
