Socio-Economic Implications Of Large-Scale Electric Vehicle Systems, Florida Solar Energy Center, Omer Tatari Jul 2017

Socio-Economic Implications Of Large-Scale Electric Vehicle Systems, Florida Solar Energy Center, Omer Tatari

FSEC Energy Research Center®

Transportation is a complex, technology-intensive socio-technical system, which needs to be tackled in an integrated manner. Also, transportation as a sector is a significant component of any national economy, and has far-reaching implications both with regard to socio-economic and environmental well-being of the society and within the context of sustainability science. For this reason, sustainable transportation is not only an important field of research within the academia but also an indispensable constituent of a sustainable economy. Therefore, investigating the path to sustainable transportation requires a holistic approach, encompassing the three dimensions of sustainability, i.e. environment, society, and economy. There are …

Techno-Economic Analyses Of Large-Scale Electric Vehicle Systems, Florida Solar Energy Center, Zhihua Qu

FSEC Energy Research Center®

This project developed the process, methodology and algorithms for computer models to evaluate the techno-economic implications of a large-scale electrified transportation sector. The model factors include developing and interacting with a network of electric vehicles and the electric grid, the infrastructure for electric vehicle charging, integrating the transportation and power systems into the urban setting, studying the impact of distributed energy storage and determining the economic impact of increased renewable energy and EVs on the electricity grid and its stability. The modeling related project results are presented in five journal articles and two conference papers. In this final report, the …


Optimal Charging Scheduler For Electric Vehicles On The Florida Turnpike, Florida Solar Energy Center, Zhihua Qu Jun 2017

Optimal Charging Scheduler For Electric Vehicles On The Florida Turnpike, Florida Solar Energy Center, Zhihua Qu

FSEC Energy Research Center®

This project developed a methodology to simulate and analyze roadway traffic patterns and expected penetration and timing of electric vehicles (EVs) with application directed toward the requirements for electric vehicle supply equipment (EVSE) siting and purchasing/leasing at turnpike plazas. The project also developed a wireless-communication-based driver-assistance application that would optimize the location and timing of charging for individual drivers as well as efficiency of the overall charging network. The first steps of the project were to develop the systematic methodology for analyzing expected penetration of electric vehicles (EVs) and their impacts on the overall transportation infrastructure. An analytical model consisting …


Transportation Planning For Electric Vehicles And Associated Infrastructure, Florida Solar Energy Center, David Block May 2017

Transportation Planning For Electric Vehicles And Associated Infrastructure, Florida Solar Energy Center, David Block

FSEC Energy Research Center®

Planning is the key to successful adoption and deployment of any new technology, and it is particularly important when that advancement involves a paradigm shift such as electrified transportation. At its core, electric transportation is largely a technology deployment. The vehicles and supporting infrastructure are unique to this mode of transportation; requiring new and specific planning and policies to support their deployment. This EVTC project brings together these planning elements and their role in the future U.S. transportation network. The project results are presented in five planning related subject areas: (1) Identification of 14 of the 22 EVTC program topics …


Prediction Of Electric Vehicle Penetration, Florida Solar Energy Center, David Block May 2017

Prediction Of Electric Vehicle Penetration, Florida Solar Energy Center, David Block

FSEC Energy Research Center®

The object of this report is to present the current market status of plug-in-electric vehicles (PEVs) and to predict their future penetration within the world and U.S. markets. The sales values for 2016 show a strong year of PEV sales both in the world and the U.S. China leads in yearly sales at 316,800 (a 53% increase for 2016 from 2015) followed by Western Europe at 209,300 vehicles sold. The U.S. is third at 159,600. These three regions comprise 91% of the global sales market. The world total of PEV sales for 2016 is estimated to be 756,000 up from …


Electric Vehicle Battery Durability And Reliability Under Electric Utility Grid Operations, Florida Solar Energy Center, Matthieu Dubarry May 2017

Electric Vehicle Battery Durability And Reliability Under Electric Utility Grid Operations, Florida Solar Energy Center, Matthieu Dubarry

FSEC Energy Research Center®

Battery degradation is extremely important to EV technologies and is a function of several factors, such as electrode chemistries, operating temperatures, and usage profiles (i.e. vehicle-only vs. vehicle-to-grid (V2G) applications). The goal of this research was to assess such impact. Laboratory testing of commercial "18650" Li-ion cells was conducted in Hawaii Natural Energy Institute's Battery Testing Laboratory. The battery test plan used two separate experiments: a cycling experiment to assess the impact of both V2G and grid-to-vehicle (G2V) charging strategies and a calendar aging experiment to assess the impact of temperature and State of Charge (SOC). The results have shown …


Electric Vehicle Energy Impacts, Florida Solar Energy Center, Katherine Mckenzie May 2017

Electric Vehicle Energy Impacts, Florida Solar Energy Center, Katherine Mckenzie

FSEC Energy Research Center®

The objective of this research project was to evaluate the impacts of electric vehicles (EVs) and renewable wind and solar photovoltaic (PV) power generation on reducing petroleum imports and greenhouse gas emissions to Hawaii. In 2015, the state of Hawaii mandated fossil fuel electric power displacement by imposing Renewable Portfolio Standards (RPS) that will reach 100% renewable electricity generation by 2045. With small, remote and isolated island electricity grids, utilities in Hawaii face unprecedented technical and economic challenges to meet these goals with exceedingly high levels of intermittent wind and PV power generation. To meet these RPS goals, EVs become …


Electric Bus Systems - A Case Study And Optimization Study, Florida Solar Energy Center, Nan Qin Mar 2017

Electric Bus Systems - A Case Study And Optimization Study, Florida Solar Energy Center, Nan Qin

FSEC Energy Research Center®

Pure electric buses (EBs) offer an alternative fuel for the nation's transit bus systems. To evaluate EBs in a transit setting, this project investigated the five electric bus fleet of the StarMetro transit system of the city of Tallahassee, FL. For the study, the implementing strategy, route distances and timings, charging times, fuel economies, impact of chargers, and maintenance and operational characteristics were analyzed. The results were compared to a baseline five diesel bus fleet. The results showed that even with a four-fold improvement in fuel efficiency, the operational costs of electric buses were only 10% lower than that for …
