The contribution of electric vehicles (EVs) in reducing greenhouse gas emissions depends on the energetic mix of the public grid. On the other hand, the public grid may become vulnerable when EVs number drastically increase, as predicted in many worldwide scenarios. Considering several scenarios, i.e., passenger EVs number, charging power values, EV consumption, and average daily urban/peri-urban trip of 20 - 60 km, and based on French power grid data, this paper investigates the power grid issues regarding the EVs charging. The results show that the total required energy for EVs charging can be assumed by the grid while the total required power may represent an issue. In order to overcome this issue, a photovoltaic (PV) powered EV charging station, including stationary storage and public grid connection as power source backups, is introduced. Based on a classic real time power management (rule-based algorithm), three case studies are analyzed. The simulation tests show that for an average daily urban/peri-urban trip of 20 - 40 km and a daily EV charging based on a slow charging terminal associated with PV-powered charging station may bring large advantage for the public grid as well for the environmental footprint.
