Car battery pack verification and charging method and system based on blockchain

Abstract

The present invention relates to a car battery pack verification and charging method based on a blockchain. The method comprises the following steps that: a car manufacturing factory purchases a battery pack to a battery production factory, determines whether the battery pack is original or not, and generates a blockchain; a user purchases the battery pack of the car manufacturing factory and generates a blockchain; a battery change device communicates with the user battery pack to perform data interaction; a charging pile communicates with the user battery pack to perform data interaction; charging is performed; and charging is finished, an order is generated and uploaded to an internet center, and a blockchain is generated. The present invention further provides a car battery pack verification and charging system based on a blockchain. The system comprises a battery production factory, an internet center, a battery change device, a charging pile, a user and a car manufacturing factory. The car battery pack verification and charging method and system based on a blockchain can perform verification of the battery pack when charging to avoid flow-in of a non-original battery pack, prevent the data of the battery pack from being tampered and ensure the reliability of replacement of the battery pack.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a method and system for verifying and charging automobile battery packs based on block chains. Background technique [0002] With the increasing popularity of new energy vehicles (electric vehicles), the problem of charging car batteries with charging piles has received more and more attention from relevant departments. The function of charging piles is similar to that of fuel dispensers in gas stations, which can be fixed on the ground or walls. , Installed in public buildings and residential area parking lots or charging stations, it can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. [0003] The so-called blockchain technology, also known as distributed ledger technology, is an Internet dat...

AI Technical Summary

Problems solved by technology

[0004] At present, the biggest disadvantage of electric vehicles is that the charging is slow. Generally, most users use the method of directly replacing the battery. The traditional charging pile charging device does not have the function of identifying whether the car battery is good or bad. Users often replace bad batteries with good ones. In addition, battery data encryption is easy to be cracked and modified, which brings great inconvenience to the operation and management of traditional charging piles
