Title:

Facilitating the Battery Charging Process in Electric Vehicles Through Connected Vehicle and Infrastructure

Accession Number:

Abstract:

Due to the tremendous political, economical, and environmental pressures the transportation sector is facing, the United States finds itself devoting more energy to innovative solutions like alternative fueled vehicle technologies. The purpose of this study was to analyze how vehicle-infrastructure communication through connected vehicle and infrastructure technologies could effectively facilitate the electric vehicle (EV) charging process at fast-charging stations. By simulating a traffic network of EVs in MATLAB, it was found that the battery charging process was optimized for EVs that were able to use vehicle-infrastructure communications to directly receive information regarding current battery state of charge and charging station conditions. The analysis was performed for the optimization of two vehicle parameters, extra travel time due to the charging and time spent in the charging station queue, as well as two charging station parameters, queue length and power output. For the simulation scenario with the largest population of EVs, the average extra travel time due to the charging and the average time spent in the charging station queue were 60% and 63% shorter for the connected EVs, respectively. Through connected vehicle and infrastructure technologies, the load balance throughout the electric grid was also evenly distributed as EVs were routed to locations experiencing lower electricity demand, resulting in minimized queue lengths and power outputs at each charging station. Most importantly, the benefits of connected vehicle and infrastructure technologies were found to steadily increase as the market penetration level of EVs also increased in the varying simulation scenarios.
