In recent years, electric vehicles have achieved rapid development, but the problems of transaction trust and data security have also followed. Therefore, this paper proposes a blockchain-based electric vehicle charging transaction model, and designs the network and transaction process of alliance blockchain supporting multi charging operators. The Hyperledger Fabric blockchain network solves the interconnection problem of different operators' devices, ensures the security and transparency of the transaction. Besides, this paper designs a Service Billing Model based on the user's reputation, and implements it with smart contract. From the results, the model well simulates the impact of user reputation on the service fee. It ensures the profitability and sustainable operation of the platform, and encourages users to improve their reputation, which is helpful for the efficient and stable operation of the transaction platform.
