EV-to-EV Charging Coordination Using a Real-Time Matching Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method for plug-in electric vehicles (PEVs) to charge each other, limiting the potential for vehicle-to-vehicle (V2V) energy transfer and sharing.
Innovation Solution
A system and method utilizing a real-time server (RTS) to facilitate V2V charging by enabling communication between PEVs for energy requests, offers, and charging parameters, along with location sharing and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PEVs charge from external power outlets or dedicated charging stations, then the battery can be recharged, but the system lacks flexibility and requires infrastructure that may not be available everywhere
Solution Approach 1:
The patent enables PEVs to charge each other directly, allowing the vehicle itself to become its own charging source. The battery in one PEV serves as the power source for another PEV, eliminating the need for external charging infrastructure. This self-service approach resolves the contradiction by making charging flexible without requiring complex external infrastructure.
Solution Approach 2:
The patent makes the PEV battery serve multiple functions: it acts as both a power storage device for the vehicle's own operation and as a mobile power source for charging other vehicles. This multi-functionality allows any PEV to potentially serve as a charging station for others, increasing charging flexibility without requiring dedicated charging infrastructure.
2Productivity
If a centralized charging management system is implemented, then charging coordination is improved, but communication overhead and system complexity increase
Solution Approach 1:
The patent divides the charging management function into distributed segments within each PEV rather than using a single centralized system. Each PEV's controller independently manages its own charging status and communicates directly with other PEVs through the RTS, segmenting the management function to reduce overall system complexity while maintaining coordination efficiency.
Solution Approach 2:
The real-time server (RTS) acts as an intermediary that facilitates communication between PEVs without requiring complex direct peer-to-peer protocols. The RTS handles the coordination logic, matching charging requests with available power sources, thereby simplifying the communication system while improving charging coordination efficiency.

AI summary
A system for a vehicle-to-vehicle charging service for plug-in electric vehicles (PEVs) includes a real-time server (RTS). The RTS wirelessly communicates with communication devices associated with individual PEVs having membership in the charging service and provides to the communication devices real-time positions of individual PEVs on a map of a terrain. The system also includes a first communication device for a first PEV configured to wirelessly transmit, via the RTS, to communication devices associated with the remaining PEVs, a request for an amount of electrical energy to charge the first PEV. The system additionally includes a second communication device associated with a second PEV and configured to wirelessly transmit, via the RTS, to the first communication device an offer to dispense the requested amount of electrical energy. The first communication device is further configured to wirelessly transmit, via the RTS, to the second communication device acceptance of the offer.
