EV Charging Request Matching for Vehicle-to-Vehicle Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of electric vehicles poses challenges due to their limited range and charging time, which requires a denser network of charging stations and increases the risk of breakdowns, with no effective solution for anticipating or facilitating breakdown assistance.
Innovation Solution
A method for managing charging requests through a communication network that allows electric vehicles to search for and combine charging offers from nearby vehicles, enabling flexible and location-based charging assistance, including breakdown support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a denser network of charging stations is deployed to address limited electric vehicle range, then charging availability improves, but infrastructure complexity and cost increase
Solution Approach 1:
The patent enables electric vehicles to autonomously request and receive charging assistance from other vehicles without requiring dedicated charging infrastructure. The breakdown assistance system allows vehicles to self-service by finding and accepting charge offers from nearby vehicles, eliminating the need for extensive charging station deployment while maintaining charging availability.
Solution Approach 2:
The patent transforms ordinary electric vehicles into multi-functional units that can both consume charge and provide breakdown assistance to others. This universal capability allows any vehicle to serve as a mobile charging station, replacing the need for specialized charging infrastructure and reducing overall system complexity.
2Ease of operation
If charging terminals are deployed to enable journey charging, then charging accessibility improves, but occupation time of dedicated spaces increases
Solution Approach 1:
The patent creates a dynamic charging ecosystem where charge availability changes in real-time based on the presence and state of nearby vehicles. Instead of static charging terminals that occupy space continuously, the system dynamically matches charging requests with available vehicles, allowing flexible, short-duration charge transfers that minimize occupation time.
Solution Approach 2:
The communication network acts as an intermediary that coordinates charging requests between vehicles without requiring physical charging terminals. This mediator enables direct peer-to-peer charge transfer, eliminating the need for intermediate charging infrastructure and reducing the time vehicles need to occupy dedicated charging spaces.
3Adaptability or versatility
If breakdown assistance through charge transfer is used, then assistance capability improves, but charging speed decreases compared to dedicated stations
Solution Approach 1:
The patent applies partial charging actions where vehicles transfer only the minimum necessary charge to reach the nearest charging station or destination. This partial action approach provides sufficient breakdown assistance without requiring full charging capacity, enabling faster, more efficient charge transfers that maintain productivity while preserving adaptability for various breakdown scenarios.

AI summary
A method for managing a charging request to charge a battery of an electric vehicle, carried out by a management entity able to communicate via a communication network. The method includes receiving a charging request to charge a battery of an electric vehicle, sent by a client terminal associated with the electric vehicle, followed by searching, among other client terminals associated with other electric vehicles, for client terminals able to respond to the charging request with charging offers, and sending a response including the list resulting from the searching, the response including a charging offer combining a plurality of charging offers.
