Abstract

More and more people choose to use electric vehicles to protect the environment and conform to the trend of sustainable development. However, the increase in the number of electric vehicles may cause problems with the overload of the grid, and electric vehicles have their shortcomings of weak range. Vehicle-to-vehicle energy trading can balance the load on the grid and alleviate the range anxiety of electric vehicles. Existing studies focus more on transaction efficiency and energy utilization, ignoring data security and user privacy during the transaction process. To this end, this paper proposes a blockchain-based V2V energy security transaction scheme, which records the data of the transaction process on the blockchain, and realizes the registration, authentication, and transaction process through smart contracts. Furthermore, we propose a transaction matching scheme, which fully accounts for both parties' credibility and uses the Bayesian game to determine the transaction price. Under the premise of an incomplete exchange of information, both parties shall ensure the reliability of the transaction and obtain the optimal price. Finally, the algorithm performance is evaluated through simulation, which shows that the scheme is close to the bidding price of both parties, and the high user satisfaction ensures a higher matching success rate for both parties. Considering the trust value matching and pricing scheme can be a good way to limit the behavior of both sides of the transaction, and ensure the credibility of both sides and the security of the transaction.
