Hybrid V2G Mobility Request System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles (EVs) face inefficiencies in energy usage, leading to larger batteries and increased total cost of ownership due to unused energy, which existing technologies have not effectively addressed.
Innovation Solution
A hybrid vehicle-to-grid and mobility service request system that compares transport requests with vehicle-to-grid energy requests to optimize energy usage by determining the most beneficial use of EV energy, either for transportation or energy discharge, using a receiving module, transport module, charging module, and grant module to select the request with the higher remuneration value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If larger batteries are used to account for unused energy, then energy storage capacity is improved, but total cost of ownership increases
Solution Approach 1:
The patent enables the EV battery to serve dual functions: providing propulsion energy and supplying energy to the grid. The system allows the battery to switch between vehicle operation mode and V2G energy discharge mode, making the same energy resource serve multiple purposes and eliminating waste of unused energy
2Productivity
If the EV provides V2G energy discharge, then energy utilization efficiency is improved, but transportation service availability may be compromised
Solution Approach 1:
The patent implements a dynamic request evaluation system that compares transportation requests with V2G energy discharge requests in real-time. The system selectively grants either transportation service or V2G service based on which request provides greater value, allowing the system to adapt its function dynamically rather than being fixed in one mode
Solution Approach 2:
The system changes operational parameters by evaluating numerical values associated with different requests (transportation vs. V2G energy discharge) and selecting the optimal mode based on comparative analysis, enabling flexible switching between functions based on current conditions

AI summary
According to one aspect, a hybrid vehicle-to-grid and mobility service request system includes a receiving module, a transport module, a charging module, and a grant module. The receiving module receives a transport request and a vehicle-to-grid (V2G) request. The transport request is associated with transport from an origin to a destination using a vehicle. The V2G energy request is associated with providing charge from the vehicle to source equipment at a charging location. The transport module determines a first numerical value associated with remuneration for the transport. The charging module determines a second numerical value associated with remuneration for providing the charge. The grant module compares the first numerical value associated with the transport request to the second numerical value associated with the V2G energy request. The grant module grants the transport request or the V2G energy request based on the comparison.
