New perspectives for the electric vehicle (EV) operation in smart grids and smart homes context arepresented. Nowadays, plugged-in EVs are equipped with on-board battery chargers just to perform thecharging process from the electrical power grid (G2V – grid-to-vehicle mode). Although this is the maingoal of such battery chargers, maintaining the main hardware structure and changing the digital controlalgorithm, the on-board battery chargers can also be used to perform additional operation modes. Suchoperation modes are related with returning energy from the batteries to the power grid (V2G- vehicle-to-gridmode), constraints of the electrical installation where the EV is plugged-in (iG2V – improved grid-tovehiclemode), interface of renewables, and contributions to improve the power quality in the electricalinstallation. Besides the contributions of the EV to reduce oil consumption and greenhouse gas emissionsassociated to the transportation sector, through these additional operation modes, the EV also represents animportant contribution for the smart grids and smart homes paradigms. Experimental results introducing theEV through the aforementioned interfaces and operation modes are presented. An on-board EV batterycharger prototype was used connected to the power grid for a maximum power of 3.6 kW.
