Electric vehicle ordered charging guiding method and system based on block chain smart contract

Abstract

The invention relates to the technical field of block chain technology and electric vehicle charging scheduling, in particular to an electric vehicle ordered charging guiding method and system based on a block chain smart contract. An electric vehicle user submits charging demand parameters to a charging platform, and a block chain system obtains the distance between the user and each charging station through a commercial map interface to form an electric vehicle user reachable charging station set and a distance matrix. And the charging station nodes call the ordered guidance model constructed in the smart contract in turn for solving, a charging station recommendation set is obtained, and calculation data is stored in a block chain system through a consensus mechanism. According to the method, the block chain technology is combined, the fairness index is introduced, the fluctuation degree of the single pile income is limited, the charging station set is provided for the user through the user selection model and the ordered charging guide model, the fairness of income distribution of a charging station operator is guaranteed, and the charging effectiveness of the user is improved.

Description

technical field [0001] The invention relates to the field of block chain technology and electric vehicle charging scheduling, in particular to a method and system for orderly charging and guiding of electric vehicles based on a block chain smart contract. Background technique [0002] In recent years, with people's attention to environmental protection, electric vehicles have developed space and opportunities as an environmentally friendly means of transportation. While many people have already adopted electric vehicles as a mode of transportation, there are still many obstacles for EV users and charging station operators to promote electric vehicles. On the one hand, electric vehicle users are highly concerned about the information of electric vehicle charging facilities (such as the location of charging stations, charging prices, etc.), and the opaqueness of information between different charging platforms will further lead to users’ mileage anxiety. On the other hand, ch...
