Investigation to Configuration and Control Methods for Electric Vehicles Charging Station Network during Large-scale Operation

Large-scale operation of electric vehicle is the only way to speed up its industrialization, and charging station network is the vital link to electric vehicle's normal operation. Charging station network is a large, dynamic, and high degree of uncertainty distributed system. And it is influenced by many factors, such as charing mode, gird safety and land price. As the requirement of charging efficiency of station network becomes higher, it is important to achieve the optimal configuration and control of charging station network, while there is no seen the systematic research of it. Therefore, the development status of electric vehicle charging station at home and abroad is analyzed followed by current research topics. Then, three key issues urgent to be solved are summarized during the electric vehicle large-scale operation, and the corresponding solutions are also proposed.
