An Efficient Blockchain-based Electric Vehicle Charging Management System

Given a charging station (CS) infrastructure, we solve the problem of an electric vehicle (EV) that needs an efficient charging program that allows it to achieve a given objective which includes: get to its destination, and keep it as low as possible the overall cost and average waiting time of the EV near each CS. Besides developing a model and method to determine a charging program that allows the EV to meet its objective, we also propose a cryptocurrency-based mechanism to realize payments for the energy received. The determined charging program and corresponding payments are managed using a smart contract (SC) executed in the blockchain, to ensure that EV charging and payments comply with the rules and are recorded in a secure, immutable, transparent and decentralized manner.
