Primary Energy Use and Environmental Effects of Electric Vehicles
Article Primary Energy Use and Environmental Effects of Electric Vehicles Efstathios E. Michaelides Department of Engineering, TCU, Fort Worth, TX 76132, USA; [email protected] Abstract: The global market of electric vehicles has become one of the prime growth industries of the 21st century fueled by marketing efforts, which frequently assert that electric vehicles are “very efficient” and “produce no pollution.” This article uses thermodynamic analysis to determine the primary energy needs for the propulsion of electric vehicles and applies the energy/exergy trade-offs between hydrocarbons and electricity propulsion of road vehicles. The well-to-wheels efficiency of electric vehicles is comparable to that of vehicles with internal combustion engines. Heat transfer to or from the cabin of the vehicle is calculated to determine the additional energy for heating and air-conditioning needs, which must be supplied by the battery, and the reduction of the range of the vehicle. The article also determines the advantages of using fleets of electric vehicles to offset the problems of the “duck curve” that are caused by the higher utilization of wind and solar energy sources. The effects of the substitution of internal combustion road vehicles with electric vehicles on carbon dioxide emission avoidance are also examined for several national electricity grids. It is determined that grids, which use a high fraction of coal as their primary energy source, will actually increase the carbon dioxide emissions; while grids that use a high fraction of renewables and nuclear energy will significantly decrease their carbon dioxide emissions. Globally, the carbon dioxide emissions will decrease by approximately 16% with the introduction of electric vehicles. -

THE PENNSYLVANIA STATE UNIVERSITY SCHREYER HONORS COLLEGE SCHOOL OF SCIENCE, ENGINEERING AND TECHNOLOGY EFFECT ON CHARGING EFFICIENCY USING GALLIUM NITRIDE DEVICES THIEN NHIEN HUYNH Fall 2014 A thesis submitted in partial fulfillment of the requirements for a baccalaureate degree in Electrical Engineering with honors in Electrical Engineering Reviewed and approved* by the following: Seth Wolpert, Ph.D Associate Professor of Electrical Engineering Thesis Supervisor Peter Idowu, Ph.D Professor of Electrical Engineering Faculty Reader Ronald Walker, Ph. D Associate Professor of Mathematics Honors Advisor * Signatures are on file in the Schreyer Honors College. i ABSTRACT Electric vehicles (EVs) and hybrid electric vehicles (HEVs) were created to lessen our dependence on natural resources. EVs and HEVs run on battery packs and the pack can be recharged from a household outlet. Because the vehicles are charged using energy draw from the grid, the problem of efficiency on a large scale become a concern. For conventional chargers, the charging efficiency may be improved due to enhanced in battery technology, charging protocol, or charging circuitry. Recently, Gallium Nitride (GaN) devices were introduced that have better performance than other semiconductors used in charging circuits. GaN has a higher bandgap than conventional materials which allows it to withstand high level of voltage. GaN can also operate at higher frequency resulting in much faster switching capability. The ability to withstand higher temperature allows GaN devices to require smaller heat sinks which effectively reduce the cost of the devices. In this thesis, a DC-DC converter as used in battery charger will be designed using Gallium Nitride devices and tested for efficiency. -

Electric Potential Difference Between Two Points
We are used to voltage in our lives—a 12-volt car battery, 110 V or 220 V at home, 1.5-volt flashlight batteries, and so on. Here we see displayed the voltage produced across a human heart, known as an electrocardiogram. Voltage is the same as electric potential difference between two points. Electric potential is defined as the potential energy per unit charge. We discuss voltage and its relation to electric field, as well as electric energy storage, capacitors, and applications including the ECG shown here, binary numbers and digital electronics, TV and computer monitors, and digital TV.
