Abstract: Cyber physical system (CPS) is an intelligent system integrating computing, communication and control. As an important gateway to the energy internet, the electric vehicle charging facilities are responsible for important functions such as power supply, metering and billing, data interconnection and charging security, which is also a typical CPS system. There are many potential threats in the charging pile terminals in the field, such as system abnormality caused by user intrusion of charging pile system, which would subsequently threaten the security of the national grid. It is therefore necessary to study and design an automatic penetration testing system for charging piles. This paper makes a research and design of the charging pile automatic penetration testing system from three aspects: fingerprint scanning, vulnerability detection and vulnerability mining, which aims to detect the known vulnerabilities and discover unknown ones, and effectively carry out all-round automatic inspection of charging electric vehicles, subsequently improving the protection level of charging piles, and strengthening the protection capability of charging piles and reducing the information leakage and economic loss caused by the attacks on charging piles.

Key words: cyber physical system, charging pile security, vulnerability detection, vulnerability mining, penetration testing
