Battery electric vehicles combined with renewable energies have a huge potential to reduce CO2- emissions, especially in the field of motorized individual transport. However, a future change from combustion engines to electric drives leads to new pro...
A PHEV demonstration project gave 80 consumers within the Northern California counties of Sacramento, Yolo and San Joaquin the opportunity to drive a PHEV-conversion for at least one month each in lieu of one of their existing vehicles. Households de...
A contactless power transfer system for charging electric vehicles requires a high efficiency, a large air gap, and a good tolerance to lateral misalignment and needs to be compact and lightweight. A double-sided winding 10 kW transformer based on a...
Using the 2009 National Household Transportation Survey (NHTS), an analysis of opportunity charging potential during daytime, for the time interval when a car or SUV is parked for the longest duration, is presented here. We focus on charging at 3.3 k...
ECOtality was awarded a grant from the U.S. Department of Energy to lead a large-scale electric vehicle charging infrastructure demonstration, called The EV Project. ECOtality has partnered with Nissan North America, General Motors, the Idaho Nationa...
Vehicles driven on alternative fuels, such as electric vehicles (EVs), are becoming more common while awareness of a diminishing oil supply, oil prices and environmental pollution are increasing. Despite technical breakthroughs, the low energy densit...
In this work we address the efficient operation of public charging stations. Matching energy supply and demand requires an interdisciplinary understanding of both the mobility of electric vehicle (EV) users and the load balancing mechanisms. As a res...
This paper describes “smart charging” systems for plug-in hybrid electric vehicles (PHEVs). The principal design feature is that the system uses gathered information to adaptively control PHEV charging, and does so in a way that allows customer PHEVs...
How did Norway get a highly developed database for charging stations, capable of real-time updates on availability, ready and free to be adopted by any country? A co-operation between Transnova, a governmental entity, and the association of EV-users...
This paper describes the processes used and the choices made while developing a procedure to evaluate Electric Vehicle Supply Equipment (EVSE) and Plug-in Electric Vehicle (PEV) chargers and provides some results of the testing process. The procedure...
