Secure Electric Vehicle Dynamic Charging Based on Smart Contracts

Abstract

Electric vehicles (EVs) have gained significant attention due to their environmental and energy-efficient benefits. Dynamic Wireless Charging (DWC) has emerged as one of the most promising EV charging methods because it overcomes the challenges associated with traditional charging stations. However, as EVs keep moving while charging, this requires specific authentication and payment methods, enabling EV mobility privacy and ensuring fair billing. To address these concerns, we propose in this paper a smart contract based solution to deal with privacy and fair billing for EVs dynamic wireless charging. The proposed solution includes a lightweight authentication mechanism enabling a continuous authenticate-and-charge process when EV is moving on the road.
