Introduction

Faced with dwindling fossil fuels and the increasingly negative impact of climate change on society, several countries have instigated national plans to reduce carbon emissions. The electrification of transport, via the extensive use of Electric Vehicles (EVs) is seen as one of the main pathways to achieve significant reductions in CO2 emissions.

To control the activities of EVs demands algorithms that can solve problems that involve a large number of heterogeneous entities (e.g., EV owners, charging point owners), each one having its own goals, needs and incentives (e.g., amount of energy to charge, profit maximization), while they will operate in highly dynamic environments (e.g., variable number of EVs, variable intentions of the drivers) and having to deal with a number of uncertainties (e.g., future arrival of EVs, energy demand, energy production from Renewable Energy Sources (RES)). Artificial Intelligence techniques such as search algorithms, optimization and multi-agent systems are proven efficient in solving such problems.
