A Secure, Intelligent Electric Vehicle Ecosystem for Safe Integration With the Smart Grid

Availability of the charging infrastructure is critical for a smooth rollout of wide-scale electric vehicle (EV) adoption. Safe integration of the charging infrastructure with the power grid heavily relies on an intelligent platform to support demand-side management and a secure information and communication system to coordinate events. However, security has been identified as an area falling short of the desired expectation in the smart grid, possibly introducing considerable risk to the reliability and stability of the power grid. In addition, a concrete demand-side management system that is compatible with state-of-the-art EVs is also lacking. This paper fills the gap by proposing a scalable defence-in-depth cybersecurity architecture for the charging infrastructure and a demand response scheme for smart EV charging. The feasibility of the system is demonstrated by implementation and testing on a real vehicle.
