Security Threats in Electric Vehicle Charging

The electric vehicle (EV) charging system plays a significant role in the future of energy systems. The widespread adoption of operating EV charging is accelerates the integration of transmission and distribution systems, this helps to accommodate a clean atmosphere and drop conventional fuel dependence. An EV interacts with different objects while recharging in the charging station. The charging stations that power up such vehicles can also be connected to the internet and make them particularly to malicious attack through hacking or remote accessing. Thus, this technology has caught the attention of many researchers who have proposed authentication protocols to provide a secure connection for exchanging information between electric vehicles and the charging station. This article discusses comprehensive security threats in the EV charging systems. Moreover, it reviews the architecture of the charging station system and the protocols between electric vehicles and charging stations.
