Scarcity of fossil fuels and pressing environmental concerns are the main driving factors towards the paradigm shift from conventional to contemporary means of energy harnessing. Likewise, transportation sector is also undergoing a tantamount change with electric vehicles now seen as an alternate to conventional internal combustion engine vehicles with the additional advantage of supplying power to...
System landscapes within logistical scenarios is highly heterogenic. Adding specific mechanisms, e.g. to support planing, monitoring and analyses for fully electrical powered vehicles, could become a mess or at least a challenge. While our project Smart City Logistic (SCL) is trying to manage this extension for multiple logistic scenarios, other projects want to do comparable system extensions as...
This paper addresses the location of parking lots (PLs) to be used for plug-in electric vehicles (PEVs) by using a probabilistic traffic model and taking into account the PL participation in electricity markets. The PLs are used both for grid-to-vehicle and vehicle-to-grid. The system includes private or public charging stations only used for PEV charging. The traffic model considers the partitioning...
The dynamic charging technology will enable Electric Vehicles (EVs) to charge their batteries while moving. Special charging pads will be placed on the roads to charge the EVs through the magnetic induction. The dynamic charging system should communicate with the EVs to only charge authorized vehicles and ensure payment integrity. This communication should be secured and should not leak any private...
With the integration of EVs into the power grid, smart metering using machine-to-machine (M2M) communication is likely to play an important role in real-time energy management and control. Smart devices embedded with advanced metering infrastructure (AMI) can forecast the energy demand as well as perform energy pricing in real time. In this paper, an artificial neural network (ANN) based intelligent...
A novel eco-routing navigation strategy and energy consumption modeling approach for electric vehicles are presented in this work. Speed fluctuations and road network infrastructure have a large impact on vehicular energy consumption. Neglecting these effects may lead to large errors in eco-routing navigation, which could trivially select the route with the lowest average speed. We propose an energy...
Electric vehicles will drive the future, therefore forecasting and simulating ‘transportation electrification’ demand over the coming years has become important for utilities. Ever since electricity was commercialized there has been a need for demand forecasting and simulation because electricity provider's ability to produce energy far exceeds their ability to store energy. This is an industry worth...
Electric roads have had a pleasant journey through the research landscape but are now about to enter the “valley of death.” The basic technologies for dynamic power transfer from the road to vehicles in motion has been developed through various research projects across the globe, largely supported by public funding. Electric road systems (ERS) will soon be tested on public roads, but is still a long...
The process of regenerative braking of an electric vehicle with source of energy - battery and ultracapacitor is subject of this work. The studied system is composed of a brushless DC motor, buck-boost DC converter and ultracapacitors. An optimization of the control system for storing maximum energy in the ultracapacitors is performed. The results are useful for the aim of improving the control of...
This paper reviews the maximum efficiency technique of powering electric and hybrid vehicles using an intelligent Inductive Power Transfer (IPT) system. The need for compensation techniques followed by a mathematical model to determine circuit parameters for efficient power transfer is presented. This is followed by discussing the concept of an intelligent charging station using the concept of Internet...
Based on existing studies to estimate Batteries State of Charge (SOC), many published papers have suggested numeric models to express the relationship between the SOC of a battery in Plug-in Electric Vehicle (PEV) and the vehicle travelled distance. Knowing the battery SOC and based on these relations, other studies concentrated on the prediction of the distance range travelled by a PEV. Reversible...
In this paper, a model predictive controller is designed to control an FEV based on the road terrain grade information and the front vehicles movement prediction. With the vehicle-to-vehicle and vehicle-to-infrastructure wireless communication technologies, two front vehicles movement information are obtained, and a Bayes Network model is applied to predict the movement of the closer preceding vehicle...
Municipal mobility agencies have tried to reduce the carbon footprint of their bus fleets using a range of options over the years, from biofuels and hydrogen to batteries and hybrid-electric diesel. A possible alternative to these options, could be the use of ultracapacitors and their capacity to offer a greener and most economical way of powering city buses. Compared to lithium-ion batteries ultracapacitors...
The paper concerns the analysis of urban electrical mini-bus power configurations based on two different energy storage systems. Full electrochemical battery power solution and hybrid power configuration based on battery and fuel cell are considered, modelled and analyzed. Performance analyses are carried out by modeling the two different powered mini-buses running along the same drive cycle experimentally...
