Electric vehicle shared battery life cycle management system and method based on block chain

Abstract

The invention discloses an electric vehicle shared battery life cycle management system and method based on block chain. The system comprises a block chain network, a user client and a battery information access node. The block chain network is developed based on the super account book platform, which is used to store the correct user information, battery information and transaction information, generate new blocks and ensure the correct growth of the block chain, and provide information inquiry service to the user client and the battery information access node. The user client is used for initiating battery lease request, providing registration service, logoff service and user information inquiry service for the user; the battery information access node is used for collecting and uploading the battery information and transaction information to the block chain. The invention stores the battery sharing information of the electric vehicle based on the block chain technology, utilizes thecharacteristic that the information in the block chain is difficult to be tampered with, ensures the safety and integrity of the sharing information, improves the fault-tolerant performance of the whole system, and develops a new mode for managing the sharing information.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and relates to a system and method for managing a full life cycle of an electric vehicle shared battery, in particular to a system and method for managing a full life cycle of an electric vehicle shared battery based on a blockchain. Background technique [0002] Electric vehicles are an environmentally friendly and convenient means of transportation. In order to solve the problems of charging difficulties and short cruising distances of electric vehicles, the concept of shared batteries has gradually emerged. In order to better understand the usage of the shared battery and manage the life cycle of the shared battery, it is necessary to record and store the production information, charging information, rental information and destruction information of the shared battery. The existing method mainly uses a centralized database to centrally record and store information. The main defects of this ...

AI Technical Summary

Problems solved by technology

[0003] 1. The protection of information integrity and non-tampering mainly depends on the control of database access rights. Once the access rights are leaked, it is easy to cause information to be maliciously tampered with and lost

[0004] 2. Centralized data storage, once the database or server fails, it will affect the stability and reliability of the entire system operation, and the robustness of the system is not high

[0005] 3. All users can only access the same database in a centralized manner. When the number of concurrent visits of users increases, the operating efficiency of the system decreases

[0007] 1. The protection of distributed databases for data security still depends on the control of database access rights, and the leakage of rights will still lead to the problem of malicious tampering of data

[0008] 2. The consistency and validity of the data of each node in the distributed database is maintained by a global database, lacking a mechanism for mutual verification between nodes, and the fault tolerance of the entire system is not high

Ethereum currently also uses the proof-of-work mechanism as the consensus layer algorithm, which is a serious waste of resources

In addition, due to its lack of user identity and authority management mechanism, it is subject to many restrictions in enterprise applications
