Abstract
Research Objective
1.Management optimization of the electric energy system. The concept is to make use of the on board energy storage of the electric and the externally chargeable (plug-in) vehicles for power balancing of the electric generation and utilization network.
2.Booster the diffusion of electrically powered vehicles with a user friendly infrastructure operation system. The concept is to establish a network of electric energy supply stations and a communication network among user, infrastructure and a management center to coordinate the charging operation according to battery state of charge, grid status and electric power production profile.
Methodology
The infrastructure system should work as bi-directional energy exchange “grid-to-vehicle” and “vehicle-to-grid”, addressing the optimization of the energy use according to availability and use requirement. The electric power network should be complemented by an IC (information and communication) network vehicle – infrastructure, managed by an Electric Infomobility Center, to supply the user with all indications concerning the approach toward the charging station and implement the appropriate energy exchange. A user friendly approach to charging station could take benefit by the technique of wireless inductive charging and from a possible automatic positioning of the vehicle on the inductive platform.
Results
A road map should be defined with the progressive steps to be implemented toward the complete system. A first step should be the establishment of a strategically distributed charging station network and an IC network to manage the charging procedure of the electrically powered vehicles, supplying the user with indication of the appropriate time, location of infrastructure with their availability and cost of charging or energy exchange depending of power system convenience. A second step could consist in providing wireless energy exchange infrastructure stations. A further step could include routing the vehicle to the nearest available station and its final automatic docking approach and positioning on the wireless point.
The technologies are basically available for the implementation of the two networks on power infrastructure and information support and the Electric Infomobility Centre development complementing the traffic control system. The implementation of the whole system postulates the coordinated convergence of multiple disciplines and involvement of the responsible Entities, as well as the relevant economics. However it is possible to envisage a positive impact of the system, once implemented, even step by step, on the benefit and finally on the environmental quality conservation.
Conclusion
This system can contribute to the easiness of use of electric and hybrid plug-in vehicles, their diffusion and finally to the conservation of the energy resources and the environmental quality.
