Optimized Recommendation of Multiple Types of Charging Stations for Charging Based on Smart Contracts

Abstract

In the rapidly evolving phase of the new energy vehicle industry, there is a shortage of charging stations for electric vehicles, leading to frequent unavailability of charging spots in parking lots. Additionally, users often have to pay high parking fees. In such a scenario, a method for sharing charging stations of multiple types is proposed. Due to the different owners of charging stations, real-time sharing of information between the charging equipment and users becomes challenging. Consequently, some charging stations remain idle for extended periods, resulting in low utilization. This paper employs blockchain technology to secure the information of both charging station owners and users. Furthermore, a multi-objective optimization algorithm is applied to consider multiple types of charging stations simultaneously, resulting in a solution that can be implemented using smart contracts.
