Integration of road electric vehicles into the smart grid system

The introduction in the mobility system of the externally chargeable electric and hybrid vehicles requires an appropriate specific supporting service and a dedicated infrastructure network. On the other hand they offer the opportunity of an effective integration in the smart grid system, as electric energy users featuring an on board rechargeable energy storage. The infrastructure system should be considered bi-directional in terms of recharging or receiving energy from the vehicles. An E-Mobility management provider should interface energy supply stations with the vehicle drivers through an ICT system to coordinate the charging request or the energy supply opportunity with the grid status, as power availability or demand. The energy exchange interface should be safe, interoperable and user friendly, according to the international Standards presently under definition and appropriate to the various categories of vehicles and environmental situations. The different possible solutions are discussed.
