Abstract：With the increasing numbers of electric vehicles, electric vehicle charging can result in traffic congestion near the charging stations during peak charging times with long wait times, power grid load fluctuations and other issues. Real-time information communication systems can be used in a charging path planning method for electric vehicles based on traffic network, charging stations and distribution network information. The system constraints include the traffic conditions, vehicle charging requirements, charging station loads, and grid loads. The multi-objective optimization function includes the travel time, number of vehicles in the charging stations, and charging loads with an improved Dijkstra method used to solve the optimization problem. Simulations show that this method improves the distribution operations, relieves traffic congestion around the charging stations, reduces the wait times and improves the usability of the charging infrastructure.
