In this paper we will discuss three different Electric Vehicle Charging Strategies known as Dumb Charge, Smart Charge and Vehicle To Grid (V2G); as well as their impacts on the Portuguese Electric Transmission Grid for a 100% Electric Vehicle Fleet scenario. The future interaction between V2G and the large-scale penetration Renewable Resources will also be analyzed.

In analysing the history of the Portuguese expansion, it is tempting to use purely economic factors. This perspective minimizes two non-economic problems confronting Portuguese society at the beginning of the fifteenth century: on the one hand the general cohesion of Portuguese society, which could only be brought about by the noble and military élites, and on the other the problem of national independence, which at the time was under threat from Castile. In fact, these problems persisted, alongside others that were generated by the very solution that was found for them, namely by overseas expansion. The capture of Ceuta in 1415 was an ingenious attempt to overcome these problems in one go. Due to their military weakness, it had been impossible for the Portuguese elites to take part in the conquest of Granada. The project of Ceuta did permit territorial growth. Besides, it mobilized the nation ideologically, thus reinforcing its identity without threatening the unity of the Respublica Christiana.
