This paper represents a new analysis method for the estimation of the required charging infrastructure for the electric vehicles (EV’s). The study is based on a real metropolitan area, taking real data from transport habits, and a prediction of certain degree of penetration of EV’s. To cope with this analysis, is the application of powerful tools, used for example in telecommunication systems such as Markov chains, and applied here into EV’s necessities and charging stations infrastructures. This theory is applied in a real example to provide more insight on how can be applied in real circumstances.
