Automatic Adjustment Mechanism of Electric Vehicle Charging Service Fees Based on Intelligent Contract

In order to improve the enthusiasm of electric vehicle users to participate in the possession of power grid regulation, and resolve the pricing problem of electric vehicle charging service fee, this paper proposes an automatic adjustment mechanism of electric vehicle charging service fee based on intelligent contract. Firstly, This paper designs the deployment architecture and transaction process of intelligent contract. After that, this paper establishes the user ' s response contribution model and the charging station revenue model. On this basis, the service rate adjustment rules considering the user ' s response contribution and the charging station revenue are designed and applied to the charging contract settlement. The differential pricing mechanism of service rate automatically adjusted according to the response effect of user participation in power grid regulation is realized.
