A Research On Blockchain-based Charging Sharing Platform Solution

In recent years,with the context of carbon peaking and carbon neutrality,the new energy industry has rapidly developed.However,while EV users have grown exponentially,the development of matching basic charging infrastructure has been relatively slow.As a result,EV users face difficulties in finding and using charging piles.Sharing of charging piles not only reduces the construction investment of charging infrastructure but also efficiently utilizes existing resources to meet the charging needs of EV users.Therefore,the topic of how to share and co-use charging piles has become a hot research topic for scholars.Private charging piles have a large base and are mostly idle during the day,making them a huge potential resource for sharing.However,the current sharing of private charging piles faces problems such as low utilization rates and difficulty in regulating the charging behavior of EV users,and most of the existing studies focus on the benefits on one side,with less in-depth discussion of the overall benefits to EV users and private charger owners.In addition,traditional charging pile sharing platforms have a high degree of centralization and cannot guarantee trustworthy transactions between EV users and charging piles,and the incentive model of the existing blockchain-based charging pile sharing platform does not cooperate with the scheduling mechanism,the incentive effect is poor.This paper proposes a private charging pile sharing mechanism based on two-sided matching to address the aforementioned problems.This mechanism utilizes two-sided matching to solve the matching problem between EVs and private charging piles.Building on this sharing mechanism,a blockchain-based model for the joint sharing of public and private charging piles is proposed.This model leverages blockchain to construct a charging pile sharing platform and designs a smart contract to enable trustworthy transactions between EVs and charging piles.The main research contents of this paper are as follows:(1)To address the problems of low utilization rates of private charging piles and difficulty in regulating the charging behavior of EV users in the process of private charging pile sharing,a private charging pile sharing mechanism based on two-sided matching is proposed.Firstly,the mechanism introduces a reputation score system for private charging pile owners to rate EV users and uses the immutability of blockchain to store the reputations of EV users.This reputation score system is then taken into consideration when matching EVs with private charging piles.Secondly,the process of the platform recommending private charging piles for EV users in the private charging pile sharing platform is equated to the two-sided matching problem between EVs and private charging piles,and the charging overhead of EV users and the comprehensive score of EV users by private charging pile owners are modeled.Then,the Gale-Shapley algorithm is used to match EVs with private charging piles and maximize overall benefits.Finally,experimental results show that the proposed mechanism can encourage EV users in the platform to improve their reputation and solve the problem of difficult regulation of charging behavior.The mechanism can also increase the success rate of matching EVs with private charging piles and improve the utilization rate of private charging piles.(2)To address the problems of untrustworthy transactions and high centralization in traditional charging pile sharing platforms,a joint public-private charging pile sharing model based on blockchain is proposed.Firstly,a framework for sharing model is designed by analyzing the feasibility and requirements of the model.Secondly,builds a local Ethereum platform and uses an Ethereum wallet to simulate transactions between EV users and charging piles.Then,designs a smart contract to ensure trustworthy transactions between EV users and charging piles.Finally,we conduct testing and security analysis to prove the feasibility of the model.
