Exploiting Blockchain for Smart Charging of Electric Vehicles: A Proof of Stake Algorithm

Abstract

The energy sector is undergoing a vast transformation. Innovations in renewable energy production, electric vehicles (EVs) and smart meters are pushing the energy sector towards decentralisation. In this context, determining the potential of distributed ledger technology (DLT) through smart contracts and interoperability between different sections of the grid is an open point. Implementation of blockchain as a DLT into the electricity distribution network with the combination of multiple components, assists decentralisation and the connection of end-users directly to the grid. In this paper, a new method is proposed to charge EVs based on fuzzy logic and distributed ledger using a proof of stake algorithm. In this way, the risk of manipulation and loss of data, which could be detrimental to the energy sector, is reduced. The decentralisation of controlling EV's charging is achieved using this technique and the data floating inside the network is immutable and protected by the consensus mechanism of blockchain.
