Abstract
In recent years, the Chinese government and State Grid Corporation of China (SGCC) have paid great attention to the technical development and infrastructure construction for electric vehicles (EVs). This paper focuses on the mechanism of Smart Battery Charging and Swapping Operation Service Network for EVs including its overall architecture and operational mode. The overall architecture based on the internet of things is analyzed and clarified through terminal device, station management and management center layers. Then two different types of demonstration projects are presented which expound on the condition of EV’s infrastructure construction. Lastly, performance analysis of the charging behaviors of electric taxis in fast charging station based on the Queuing theory is proposed. The simulation results show that the service time and the number of generators has an influence on the average waiting time and the length of queue.

Operational service network of EVs is comprised of battery identity, power cells, charging facilities, user owner, smart grid and so on, which are linked through GPRS/ 3G, Wi-Fi, Internet, using technologies such as radio frequency identification devices (RFID), sensors, image recognition
This paper firstly analyzed and built the overall architecture of the smart battery charging and swapping operational service network for EVs in China based on the research of State Grid Corporation of China (SGCC)
Summary
As an important prerequisite and conditions for grid largescale integrations electric vehicles (EVs), the battery. This paper firstly introduces the overall architecture and functions of smart battery charging and swapping operational service network for EVs, and related demonstration projects in China, and evaluates their performances and benefits. A model used for battery management is proposed in this paper
