EV Charging Data Linkage for Blockchain Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in uniquely identifying and recording the usage of electric power from renewable sources, particularly for electric vehicles, as they lack a means to distinguish individual vehicles when charging data is recorded on a blockchain network.
Innovation Solution
A device and system that includes a memory for storing acquirer identification information and circuitry to receive provider identification information, measure, and transmit data to a blockchain network, enabling the tracking and verification of renewable energy usage for electric vehicles by associating specific vehicles with their energy sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging data is recorded at a charging facility on a blockchain network, then data management and verification are improved, but the ability to uniquely identify individual electric vehicles is lost
Solution Approach 1:
The patent introduces an intermediary device (portable terminal or onboard device) that acts as a mediator between the charging facility and the blockchain network. This intermediary carries vehicle identification information and transmits it along with charging data to the blockchain network, enabling both data verification and unique vehicle identification to coexist.
Solution Approach 2:
The patent uses copying by creating a digital representation of vehicle identification information (such as vehicle ID, license plate number, or owner information) that is stored in the intermediary device. This copied information is then transmitted to the blockchain network alongside charging data, allowing verification without requiring direct vehicle presence or complex vehicle-to-blockchain communication.
2Loss of information
If identification information is stored and transmitted to blockchain network, then vehicle identification capability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the intermediary device (portable terminal or onboard device) to autonomously store vehicle identification information and automatically transmit it to the blockchain network during charging operations. The system performs identification and data transmission functions without requiring manual intervention or complex centralized management infrastructure.
