Futuristic model of Electric Vehicle charging queues

摘要

The big hurdle in the PEVs (Plug-in Electric Vehicles) penetration is the short driving range and long battery charging time. Even though widespread deployment of public charging stations are soon expected, the public is concerned about being stranded or waiting for long time in charging stations. To effectively address this problem, this paper develops two fold solutions. First, computer models for estimating various discharging profiles of PEV batteries considering different regional driving cycles is developed. It is found that each driving cycle generates a unique discharging profile. Moreover, a unique utility function is construed which is optimized to minimize the overall waiting time for consumers and to harmonize the queue size in each charging station. This model uses Toronto downtown area as a case study, and suggests potential locations for the new charging stations to minimize driving distance to the charging station and overall wait time.
