Optimal Incentives

As electric vehicles’ penetration increases, more impacts on urban systems are observed and related to both driving (e.g., on traffic congestion and reduced pollution) and charging (e.g., on the electrical grid). Therefore, there is a need to design coupled incentive mechanisms. To propose and numerically evaluate such incentives, a game theory model is adopted. Its originality comes from the coupling between the charging cost and the driving decisions: to drive downtown or to charge at an e-Park & Ride hub with solar panels and then take public transport, in order to reach destination. Optimal ticket fares and solar park’s size are computed using real photovoltaic production data.

Transportation Sector

Electric vehicles are the latest form of technology developed to create an environmentally friendly transportation sector and act as an additional energy source to minimize the demand on the grid. This comprehensive research review presents the vehicle-to-grid (V2G) and the vehicle-to-home (V2H) technologies, along with their structures, components, power electronic topologies, communication standards, socket structure, and charging methods. In addition, the charging topologies in V2G and V2H are given in detail. This study is planned as a useful guide for future studies that can be achieved in that it compares the results obtained and analyzes the studies in the literature, finding the advantages and disadvantages of charging topologies in V2G and V2H.

In this project, a system was designed for charging batteries in electric vehicles using photovoltaic panels. Low cost of operation, cheap construction and simple user interface were among the main criteria taken into account. Each energy source was carefully selected and modules were used so that they could power the microcontroller and charge the energy storage source. The solution was patented [1]. This article is a part of a project related to the design of digital control devices with electric drives carried out at the UWM. The control system solutions developed at UWM have been published in the book {15}.

This article presents a critical analysis of all the major pathways to produce hydrogen and to utilize it as an energy carrier to generate heat or electricity. The approach taken is to make a cradle to grave analysis, including the production of hydrogen, the conversion of hydrogen to heat or electricity, and, finally, the utilization of that heat or electricity for a useful purpose. This methodology shows that no currently available hydrogen pathway, irrespective of whether it uses fossil fuels, nuclear fuels, or renewable technology as the primary energy source to generate electricity or heat is as efficient as using the electric power or heat from any of these sources directly. Furthermore, electric vehicles using batteries to store electricity are shown to be more efficient and less polluting than fuel cell powered vehicles using energy stored in hydrogen produced by electrolysis of water.

Super Capacitors

As the Super Capacitors have Higher Specific power density, longer life time and safer operation when compared with any other energy source in Electric Vehicles, thus have more attention in the present market. Thus presently Super Capacitors are used to act as intermittent source. This study would deal with the performance analysis of Electric Vehicles by adopting Super Capacitor as the only Energy source without any Backup. The SC can charge and discharge at a very faster rate, the time taken for the charge is also equal to the time taken for discharge. Thus the SC will discharge at a very faster rate, in this regard to improve its discharging rate we would like to do certain Design Modifications. The Main objective of this study is to replace the energy source in the EV’s with Super Capacitor Bank which would reduce the weight, Maintenance, and increase the performance of EV’s in a long run.
