Blockchain and Smart Contract Payment for Electric Vehicle Charging

Abstract

Our research aims to study, design and build the electronic payment system for electric vehicle (EV) charging using blockchain and smart contract technologies. Both technologies are used to control and manage payments and to decentralize the payment system, so the devices can automatically pay each other. In addition, our system lessens the inadequate of charging station for EV when travel in the long distance because our proposed let EV owners who also have charging facilities at their homes share their facilities and automatically get paid. Blockchain node is set up in charging station and is controlled by the application for EV owners. The application can show the charging information and control the payment and charging process automatically. For EV part, we simulated the data transmission between charging station and EV.
