Research On Intelligent Contract Application Of Charging Pile System Based On Blockchain

At present,the construction of China’s charging pile infrastructure is not compatible with the development of electric vehicles,mainly reflected in the small number of charging piles,unreasonable layout,and the large number of private charging piles are idle,which makes it difficult to charge electric vehicles.In view of the above problems,this paper uses blockchain and smart contract technology to build a charging and discharging transaction sharing platform to improve the efficiency of existing charging piles and the sharing of private charging piles,and to ensure the security of information in the platform.This paper first studies the problems of blockchain technology and electric vehicle charging piles,and studies the combination of charging pile and blockchain technology.Analyze the characteristics of blockchain technology and its commonly used consensus algorithms,encryption algorithms and smart contracts.Secondly,according to the development requirements of the Ethereum smart contract,the smart contract that meets the charging transaction is designed.A four-layer architecture is designed in the platform.Each layer architecture has different functions,and each layer is combined with each other to form a charging pile sharing platform.Thirdly,the raiden network is used to expand the throughput of the blockchain,and the transaction form under the expansion method forms a complete transaction process to meet the commercial needs.Through the analysis of the application of raiden network,the change of its throughput and transaction cost is obtained.Finally,according to the design of the four-tier transaction architecture,the Ethereum development environment is used to complete the development of the shared platform.
