Key Security Challenges for Electric Vehicle Charging System

With the proliferating of electric vehicles, charging infrastructure has developed rapidly. Meanwhile, security issues of smart charging station system are becoming increasingly serious. In this paper, we systematically analyze the architecture of the charging station system and the protocols between electric vehicles and charging stations. Furthermore, we present the security issues and challenges of the charging station system including charging protocol, TCU, and the communication between the charging station and the vehicle networking platform. As far as we know, our work is the first practical and systematic work for the security analysis of smart electric vehicle charging stations system.
