To advocate consumer adoption of Plug-in Electric Vehicles (PEVs), many institutions and organizations have implemented free-of-cost access to public charging stations for any PEV driver. On the basis of charging event data collected from public charging stations in Rochester, NY, 54% of the total time duration occupied by PEV users is spent parking without charging, indicating significant operational inefficiency; time spent parking without charging could be better utilized by other PEV drivers needing to charge their vehicles. This paper examines the variation in this operational inefficiency across geographic and temporal factors. A discrete event simulation is used to model the PEV charging stations and test the effectiveness of time limit policies on reducing charging station inefficiencies. The effects of time limits on customer service rates and customer satisfaction metrics are also examined. Finally, the impact of time limit policies are evaluated as PEV market penetration increases from the present level to a 20% market share. Results indicate the time limit policies have the potential to significantly reduce charging station inefficiencies without impacting drivers significantly, but that these results are location dependent. The results also show that maintaining similar levels of station accessibility across EV penetration rates can be accomplished by implementing charging station time limits.
