The push toward widespread adoption of electric vehicles includes plans for a national network of EV chargers—and new tools to protect them from cyber threats. Researchers at US national laboratories are collaborating to secure EV charging infrastructure so that threats can be detected and quickly eliminated. In summer 2022, the DOE’s Electric Vehicle Secure Architecture Laboratory Demonstrations group (EV SALaD) tested a new tool to detect and mitigate cyber threats. The test compromised the power and electronics modules and thermal management systems of a 350-kilowatt, commercial extreme fast charger in an attempt to alter the information shared between the vehicle and the driver. A Safety Instrumented System Core interface was installed between the charging station and its power cabinet to monitor the flow of information and detect abnormal behavior. The device successfully intercepted 75% of the test intrusions. Pacific Northwest National Laboratory is now conducting additional research.
