At present, there are still some problems about the credible evaluation and management of electric vehicle charging station. In response to such problems, in order to enable more effective evaluation and management of electric vehicle charging stations, and to enable users to obtain a good user experience, this paper proposes a credibility mechanism for electric vehicle charging stations based on a double-layer blockchain. The current credibility mechanisms are all built on the basis of centralization. Once the central server is compromised, it is extremely prone to irreparable situations such as system paralysis. In order to improve the efficiency of consensus in the existing blockchain, this article proposes a method of combining roulette with a consensus mechanism to prevent monopoly, cheating, and improve system efficiency. Through extensive analysis and experimental results, it is proved that the trusted mechanism can well reflect the quality of the charging station nodes, and the addition of roulette can stimulate the positive behavior of each block node.
