EV Power Transaction Management for Secure Vehicle-to-Vehicle Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power transaction systems for electric vehicles lack convenience and reliability, particularly in managing power feeding between movable objects, and are prone to data falsification.
Innovation Solution
A transaction management system that includes a power feeding management apparatus and a transaction management apparatus, which acquire and transmit identification and transaction information via a communication network, enabling secure and reliable power transactions between power feeding and receiving sides, using units like power feeding side identification information acquiring units, power receiving side identification information acquiring units, and transmission units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power transaction systems are implemented for electric vehicles, then power transfer capability is improved, but reliability and convenience are insufficient and data falsification occurs
Solution Approach 1:
The patent introduces a charging cable as an intermediary device between the power feeding vehicle and power receiving vehicle. This charging cable includes a control box that acts as a mediator to manage power flow and information transmission, thereby improving reliability while distributing system complexity across multiple components rather than concentrating it in a single complex system
Solution Approach 2:
The system is divided into separate functional components: power feeding vehicle, power receiving vehicle, charging cable with control box, and transaction management server. Each component handles specific tasks independently, which improves overall system reliability through modular architecture while making the system more manageable despite the increased number of components
2Ease of operation
If identification and transaction information are transmitted via communication network, then transaction management capability is improved, but data security against falsification becomes critical
Solution Approach 1:
The control box continuously monitors power flow parameters and communicates with the transaction management server to verify transaction data. This feedback mechanism ensures that any attempted data falsification can be detected and corrected, allowing convenient automated transaction management while maintaining data integrity through continuous verification
Solution Approach 2:
The transaction management server acts as a trusted intermediary that receives, verifies, and records all transaction information. By routing all communication through this centralized intermediary with authentication capabilities, the system enables convenient automated transactions while protecting against data falsification through centralized verification

AI summary
The apparatus includes: a power feeding side identification information acquiring unit that acquires power feeding side identification information for identifying the power feeding side from a device or a user's communication terminal in the power feeding side; a power receiving side identification information acquiring unit that acquires power receiving side identification information for identifying the power receiving side from a device or a user's communication terminal in the power receiving side; a power feeding information acquiring unit that acquires power feeding information about a power amount fed from the device in the power feeding side or a power amount fed to the device in the power receiving side; and a transmission unit that associates with one another: the power feeding side identification information; the power receiving side identification information; and the power feeding information, and transmits them to a transaction management apparatus.
