Abstract
The U.S. Department of Energy (DOE) through its Vehicle Technologies Office (VTO), often in close partnership with industry, has supported the development/deployment of cleaner, more efficient automotive technologies with electric drive systems. This paper provides an overview of efforts to promote market adoption of hybrid electric vehicles (HEVs) and electric vehicles (EVs) in the U.S. and the associated VTO R&D and Deployment initiatives for accelerating this adoption. It also highlights the many significant research breakthroughs resulting from R&D in the hybrid vehicle systems areas of research (with particular emphasis on advanced electric drive technologies) funded directly by or in collaboration with VTO.
Highlights
Lambda Technologies is developing variable frequency microwave (VFM) drying technology which employs penetrating energy that selectively targets the solvent in the entire volume of the wet electrode. (In contrast, convection dryers only heat the electrode surface and solvent removal proceeds layer by layer which takes much longer.) Variable Frequency Microwave (VFM) is estimated to result in a 30-50% reduction in the operating cost of the electrode drying procedure
Combined in situ x-ray diffraction (XRD) and electron energy loss spectroscopy (EELS) measurements indicate that Mn and O both reversibly contribute to the charge transfer with oxygen providing almost half of that capacity
Department of Energy (DOE) Vehicle Technologies research and development (R&D) activities for hybrid electric systems are focused on electric drive technologies, advanced batteries, and vehicle systems for transportation applications and currently emphasize plug-in electric vehicles (PEVs)
