PAT DAVIS, VEHICLE TECHNOLOGIES, DEPT. OF ENERGY - WASHINGTON D.C. AUTO SHOW 2011

EV Channels Review

This interview from the 2011 Washington D.C. Auto Show features Pat Davis from the Department of Energy discussing current and future vehicle technologies. Key topics include the progress and challenges of flex-fuel vehicles and E85 infrastructure, the rollout of 23,000 charging points for electric vehicles, and the ambitious goal of one million plug-in vehicles by 2015, which Davis believes is achievable based on manufacturer announcements. The discussion delves into battery technology, highlighting DOE's role in developing nickel-metal hydride and lithium-ion batteries, with a projection of significant cost reductions by 2015. Tesla's use of 18650 laptop batteries is contrasted with the trend towards larger, fewer cells. Cold weather impact on EV range and the role of plug-in hybrids in alleviating range anxiety are also explored. The conversation touches upon grid capacity, the concept of a smart grid, and the DOE's continued support for advanced combustion engine R&D, emphasizing that a combination of electrification and low-carbon fuels is crucial for substantial reductions in petroleum consumption and greenhouse gas emissions. Compressed Natural Gas (CNG) is noted as a viable option, particularly for medium-duty fleet vehicles.
