Methods To Increase Fuel Efficiency In Post-Production Automobiles, Hope J. Corsair
Methods To Increase Fuel Efficiency In Post-Production Automobiles, Hope J. Corsair
TREC Final Reports
While much focus has been placed upon the identification of completely novel technologies for the future of personal transportation world-wide, the majority of the US and the world at large will be reliant upon petrol for personal transportation well into the future. While EVs, alternative fuels, and hybrid cars have all started to make an impact on the market, with varying amounts of success and consumer accessibility, their relative market share is and is projected to continue to be low. Furthermore, a large segment of the population is not readily able to ever purchase a new car as a consumer …
The Development Of Low-/No-Emission Electric Vehicle Infrastructure In The Portland Metro Region: A Roadmap, John Macarthur, Peter Murchie, George Beard
The Development Of Low-/No-Emission Electric Vehicle Infrastructure In The Portland Metro Region: A Roadmap, John Macarthur, Peter Murchie, George Beard
TREC Final Reports
The shift from combustion engines to low- and no-emission electric vehicles is underway and gaining momentum. During the last year, Oregon has become an active player in the electric vehicle arena, with a number of promising relationships and activities in the early stages of formalization. With additional thought, effort and strategy Oregon can seize the opportunity to become the national leader in the adoption and incorporation of new vehicle platforms and mobility strategies into the fabric of urban life and the built environment. Oregon is currently actively engaged in relationships with international automotive companies and local businesses and utilities interested …

Modeling Of Dc Link Capacitor Current Ripple For Electric Vehicle Traction Converter, Lei Jin, Julia Zhang
TREC Final Reports
Contemporary Full Hybrid Electric Vehicle/Plug-in Hybrid Electric Vehicle/Battery Electric Vehicle (FHEV/PHEV/BEV) products use one or more DC/AC power converters, also known as traction inverters, to convert the DC voltage/current provided by the traction battery to the AC voltage/current to drive the traction motor(s). Large and bulky DC link capacitors are used at the input of the traction inverter to provide a smooth DC input voltage. Those DC link capacitors, occupying almost 50% of the space in the whole package, can contribute to more than 20% of the total cost of the traction inverter. They are generally over designed to assure …

Electric Vehicle Charging Infrastructure Community Needs Assessment, Robert Parker, Juli Brode, John Rowell
TREC Final Reports
Dependence on fossil fuels, climate change, and degraded air quality are forcing the auto industry and consumers to seek alternative solutions to the current transportation system. Significant technical breakthroughs are allowing automakers to develop electric vehicles (EVs) that transcend some of the key barriers that limited them historically. Plug in electric vehicles entered the Oregon marketplace in early 2011. A range of reports suggest the demand for EVs will grow rapidly once affordable highway speed vehicles become available. ODOT identified the lack of a reliable network of electric vehicle service equipment (e.g., charging stations) that increases the range of these …
Impacts Of Low-Speed Vehicles On Transportation Infrastructure And Safety, Katharine M. Hunter-Zaworski, Linda Cornell
Impacts Of Low-Speed Vehicles On Transportation Infrastructure And Safety, Katharine M. Hunter-Zaworski, Linda Cornell
TREC Final Reports
There are increasing numbers of low-speed electric vehicles (LSVs) on public roadways. These vehicles are designed to be used within protected environments and on roadways with a maximum posted speed of 25 mph. Currently these vehicles are not subject to the same federal requirements for occupant protection as passenger cars. This research project investigated safety standards, operating regulations, and LSV manufacturer materials from sources around the world. The purpose of the research was to determine positive and negative impacts that LSVs, including Neighborhood Electric Vehicles (NEVs) and Medium Speed Electric Vehicles (MSEVs), are likely to have for the Oregon Department …
