We study the problem of routing vehicles with energy constraints through a network where there are at least some charging nodes. We seek to minimize the total elapsed time for vehicles to reach their destinations by determining routes, as well as recharging amounts when the vehicles do not have adequate energy for the entire journey. For a single vehicle, we formulate a mixed-integer nonlinear ...

Electric vehicles (EV) are considered a practical alternative to conventional and hybrid electric passenger vehicles, with higher overall powertrain efficiencies by omitting the internal combustion engine. As a consequence of lower energy density in the battery energy storage as compared to fossil fuels powered vehicles, EVs have limited driving range, leading to a range phobia and limited cons...

Electric vehicles (EVs) charging algorithms considering a photovoltaic (PV) system have been studied in this paper. The power needed to charge the EVs comes from gridconnected photovoltaic generation or the utility. This work includes the issues such as how to maximize photovoltaic generated power and reduce energy cost of EVs charging, that is important for the integration of efficient EVs cha...

axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

this paper proposes a novel decision making framework for an electricity retailer to procure its electric demand in a bilateral-pool market in presence of charging and discharging of electric vehicles (evs). the operational framework is a two-stage programming model in which at the first stage, the retailer and ev aggregator do their medium-term planning. determination of retailer's optimum sel...

China promoted the large-scale adoption of Electric Vehicles (EVs) in its 13th five-year plan; however, this target faces many obstacles. This paper analyzes the main barriers to widespread adoption of EVs through a survey in Shenzhen, which has the biggest EVs market share out of China’s major cities. Based on previous research, this paper conducted a new study using 406 approved questionnaire...

This paper presents a framework and methodology to characterize the uncertainty of the consumption in the Electric Vehicles (EVs). A Fuzzy Logic (FL) is implemented to obtain an interval of the probability that the energy consumption may take. The framework assumes the availability of Information and Communication Technology (ICT) technology and previous data records. A case study is presented ...

In this paper the impacts of a large deployment of electric vehicles (EVs) on selected distribution grids of the Hellenic Distribution Network are assessed. Mainly technical restrictions are taken into account, such as voltage limits, branches’ congestion levels or losses’ evaluation. EVs are considered as simple loads that charge from the grid. The analysis takes into account driving profiles ...

The widespread diffusion of electric vehicles (EVs) suffers from the lack of a well-developed public charging infrastructure, which currently is uneconomical to develop for investors. Many owners of EVs have private charging stations at their premises, which yield unlockable potential due to high idling times. In line with sharing platforms for other goods like accommodations and cars, we prese...
