Increasing the number of electric-drive vehicles (EDVs) on America’s roads has been identified as a strategy with near-term potential for dramatically decreasing the nation’s dependence on oil―by the U.S. Department of Energy (DOE), the federal cross-agency EV-Everywhere Challenge, and the automotive industry. Mass-market deployment will rely on meeting aggressive technical targets, including improved efficiency and reduced size, weight, and cost. Many of these advances will depend on optimization of thermal management. Effective thermal management is critical to improving the performance and ensuring the reliability of EDVs. Efficient heat removal makes higher power densities and lower operating temperatures possible, and in turn enables cost and size reductions. The National Renewable Energy Laboratory (NREL), along with DOE, industry and research partners is working to develop cost-effective thermal management solutions to increase device and component power densities. In this presentation, the activities in recent years related to thermal management and reliability of automotive power electronics and electric machines will be presented.
Sreekant Narumanchi is the Supervisor of the Advanced Power Electronics and Electric Machines (APEEM) Section at NREL. He leads a team of 10 researchers focused on thermal management and reliability of power electronics and electric machines. His broad research interests include heat transfer, power electronics and motor thermal management, packaging and reliability. He has published over 50 peer-reviewed papers and book chapters. He is also active professionally as a reviewer and on the editorial board for journals and conferences in the area of heat transfer, thermal management and electronics packaging, as well as for the Department of Energy. He received the Best Paper Award from the ASME Journal of Electronic Packaging (2003), the ASME InterPACK Conference Outstanding Paper Award (2013), as well as several Performance and Business Collaboration Awards at NREL. He received his Ph.D. from Carnegie Mellon University (2003), M.S. from Washington State University (1999), and B. Tech. from Indian Institute of Technology - Kanpur (1997), all in Mechanical Engineering.
