Design of Energy Block Chain System Supporting Electric Vehicle Charge and Discharge Trading

Abstract

As one of the underlying supporting technologies of Energy Internet, energy blockchain has attracted more and more attention. How to combine energy blockchain with specific application scenarios is a difficult problem in current research. Firstly, the technical feasibility of the application of energy blockchain in the field of energy trading is analyzed in detail. Then, taking the scenario of electric vehicle charging and discharging trading as the breakthrough point, considering the convenience and security of both sides of the transaction, a blockchain system framework supporting consensus algorithm and intelligent contract is proposed, which includes blockchain layer and intelligent contract. There are four layers of architecture: extension layer, application layer and presentation layer. Finally, from the perspective of system platform development, the technical connotation and application demonstration based on ethereum architecture are introduced. The system architecture and its application effect provide technical reference for promoting the integration of energy system and information technology and improving energy efficiency.
