Study About Electric Vehicle Routine Optimizing and Analysis of Charging Stations’ Layout in Beijing

Abstract

This paper analyses the locations of electric vehicle charging stations in Beijing and focuses on the solution to the problem of how to look for charging stations to replace batteries when electric vehicles are in Low Level. Considering the traffic conditions in Beijing and analyzing the process of electric vehicles researching charging stations, this paper establishes a multi-objective programming with two objects: the shortest total distance and the largest dump energy after arriving destination. This mode is resolved with linear weighted sum method. One hundred tests are made and charging times of each charging station and bypass distance of each charging stations are calculated. Through analysis of above statistics, this paper concludes that the layout of charging stations in Beijing is not reasonable, because charging stations are not equally distributed.
