This work describes the impact of integrating electrical vehicles (EV) in the electrical energy network, through the simulation of the electrical consumption of residential users in the absence of intelligent management strategies such as Smart Grids. The study is composed by a first data analysis stage of three types of family (small, medium and large) and a second stage describing a scenario simulation of EV integration using the identified consumption profiles. This simulation evaluates the electrical network limitations and other factors influencing the EV charging. The main results achieved are the charging curves for the residential consumption identifying the available power for the EV. The user profiles obtained will enable studies for assuring not only charging at residences but also in other charging points. © 2011 AISTI. Source

The next big step in the evolution of the automotive industry is the introduction of electric vehicles (EV), however has associated limitations of autonomy and in conjunction with this limitation, extended charging times, very few points of charging and smart electricity grids very embryonic. In this context, is requires a very rigorous planning of daily use of the EV. Thus, this work presents an information system that aims to help the driver in the daily use of the EV in order to deal with the charging problem, minimizing the problem of anxiety to archive the objectives through the continuous monitoring of the autonomy of the vehicle and the timely submission of relevant information related to charging process, also allowing the storage the energy transactions for later analysis and further improvements. Similarly, given the limitations of the electrical distribution network and taking into account N simultaneous charging process a management system is proposed to deal with this problem, in order to limit the total power consumed in each moment. © 2011 AISTI.

The current work deals with the problem of growing population in the cities and the associated mobility problems. For this problem it is proposed a Multi-Modal Transportation Advisor system, based on the integration from different data sources such as public transportation systems, car and bike sharing or car pooling. Taking into account real time traffic information the system shows best option for a user goes from point A to a point B and calculates the associated trip cost. This is part of the European Project START, where we show the contribution of a public transportation ontology for different DB integration and a best path advisor based on an appropriate Dijkstra's algorithm implementation. © 2011 IEEE.
