Preliminary tests results about E-car harmonic emissions

The increasing number of electric cars present in our cities goes to analyze the impact that these vehicles have on the distribution network. The collaboration of Enel in the European project "Green E-Motion" has led to the construction of a laboratory measurement at the Enel Test Center of Milan. The laboratory allows on-the-field test for the evaluation of different characteristics of system voltage and absorbed current during charging of electric vehicles. In this paper the results of several measurements are discussed: in particular about the effects of the contemporaneously charging of different electric vehicles.
