Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately identify electric vehicles for energy distribution transactions, preventing efficient metering and revenue recognition for energy delivered to them.
Innovation Solution
A method and system that couple an electric vehicle to an energy delivery point via a connector, receive a unique identifier, determine the associated account, and facilitate energy delivery and transaction processing, using broadband over powerlines communication to enable automatic identification and billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If broadband over powerlines communication is used to transmit vehicle identifier and billing information, then communication capability is improved, but electrical noise and interference increase
Solution Approach 1:
The patent introduces a mediator device (communication interface/broadband modem) that couples between the power distribution system and the vehicle identification/billing system. This intermediary enables reliable data transmission over power lines by handling signal conditioning and protocol conversion, thus improving communication capability while isolating the core power distribution system from noise-related harms.
2Productivity
If automatic identification and billing systems are implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent merges previously separate functions (vehicle identification, energy metering, billing processing, and communication) into an integrated system where a single connector and control unit handle multiple tasks. This consolidation improves productivity by enabling automatic end-to-end processing while managing complexity through functional integration rather than proliferation of separate components.
Solution Approach 2:
The connector and control system are designed with multi-functionality, serving both as an electrical connection point and as a communication interface for vehicle identification and billing. This universal design enables automatic identification and billing processes without requiring additional dedicated hardware, thus improving productivity while containing device complexity.

AI summary
A method for delivering energy to an electric vehicle includes coupling the electric vehicle to an energy delivery point via a connector, receiving a unique identifier of the electric vehicle via the connector, determining an account associated with the identifier, delivering an amount of energy to the electric vehicle via the connector, and determining a transaction amount based on the amount of energy delivered to the electric vehicle by the energy delivery point.
