Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle-to-grid (V2G) communication standard lacks a defined communication interface for charge schedules and efficient billing policies, hindering effective energy transfer and billing processes between electric vehicles, supply equipment, and power grids.
Innovation Solution
A communication method and system that includes an electric vehicle communication controller to transmit charge schedule information, including start and finish times and energy amounts, to a supply equipment communication controller and power grid operation server, enabling efficient billing and energy transfer by defining a communication interface for charge processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing V2G communication standard is used, then basic power transmission is enabled, but no specific communication interface is defined for charge schedules and efficient billing policies
Solution Approach 1:
The communication interface is segmented into distinct message types including charge schedule requests, charge cost calculations, and billing policy notifications. This segmentation allows each aspect of the charging process to be communicated through dedicated message formats, enabling comprehensive charge schedule management and efficient billing without requiring a complete communication protocol overhaul.
Solution Approach 2:
A message broker or communication controller is introduced as an intermediary between the power transmission system and the billing system. This intermediary handles the translation and routing of charge schedule information, mileage data, and cost calculations between different system components, ensuring that billing policy information is properly captured and transmitted without disrupting the existing power transmission functionality.
2Productivity
If charge schedule information is transmitted to multiple systems, then billing efficiency is improved, but communication complexity increases
Solution Approach 1:
The communication controller is designed with multi-functionality to handle multiple communication tasks through a unified interface. It can simultaneously manage power transmission commands, charge schedule coordination, cost calculations, and billing policy notifications through standardized message formats. This universal approach allows charge schedule information to be transmitted to multiple systems without requiring separate dedicated interfaces for each function, thereby improving billing efficiency while controlling communication complexity.
