Matthew Keyser joined NREL in 1992 and today manages the electrochemical energy storage group in the Center for Integrated Mobility Sciences. This group includes the energy storage team, which conducts modeling, simulation, and systems evaluation activities to assess and optimize energy storage components at the materials, cell, pack, and systems levels, as well as the power electronics team, which develops power electronics and electric motor technologies with greater dependability, efficiency, and durability.
During his decades-long tenure at the lab, his research has focused on various aspects of advanced vehicle technologies and systems. He developed an assortment of finite element thermal and structural models for hybrid electric vehicle components. He also fostered the growth of NREL’s energy storage research equipment and facilities, which now span more than 6,000 square feet of laboratory space and enable electrochemical material fabrication, safety analysis and characterization, and world-class thermal characterization.
He played a key role in the invention of NREL’s R&D 100 Award-winning Isothermal Battery Calorimeters, which make it possible to accurately measure heat generated by electric-drive vehicle batteries, analyze the effects of temperature on battery systems, and pinpoint ways to manage temperatures to optimize performance and lifespan.
Before coming to NREL, he worked in the military industry, performing structural and thermal finite element analyses for power supplies subjected to severe vibration, shock, and thermal environments.
