Secure wireless communication platform for EV-to-Grid research

Abstract

"Vehicle to Grid" power or V2G will be a new green energy scheme that allows electricity to flow from Electric Vehicles (EVs) to power lines. The objective of this paper is to design and develop a secure wireless communication platform for V2G research, with the aim to develop a suitable wireless test bed for the V2G in Singapore. First, this paper presents our system block diagram and required methods design which include V2G architecture design, integrated OBU (on-board unit) design, base station (Aggregator), Telematics, V2G authentication protocol, and schedule optimization of EVs against Grid conditions. It then focuses on the authentication protocol for secure wireless communications between the Aggregators and EVs. It addresses the new and special challenges related to EVs, such as large overhead and latency, which are crucial for secure wireless communications with dynamic and fast moving EVs. Finally, the paper presents the initial test results and shows that our authentication protocol can securely protect the exchanged information with less overhead and less authentication latency.
