Electric and hybrid vehicles battery charger cluster locations in urban areas

The cluster of EVs´ battery chargers is expected to become reality in many European cities in the near future. The strategy for positioning these chargers on the streets, especially in the urban city centres should include numerous parameters, where some of them may not be technical. The paper presents a proposal of procedure for placing the set of battery charger clusters in a city centre. Two examples are presented in a case where there are restrictions on building the new electricity infrastructure and expectation that charging time is short. The main concern is placed on power quality issues, as current harmonic distortion may be very high. It is shown that clusters with 2 to 6 chargers are found to be the most suitable. It is also noticed that current distortion is getting lower as number of chargers is increasing.
