EV Recharge Request Matching With Combined Peer Charging Proposals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited range and longer charging times of electric vehicles compared to thermal vehicles pose challenges in managing battery recharging efficiently, particularly in situations where vehicles need to be recharged on the move, leading to potential breakdowns due to insufficient battery charge.
Innovation Solution
A method that allows electric vehicle owners to request recharging through a communication network, where a management entity searches for and combines recharge proposals from nearby vehicles, optimizing location, time, and charge quantity to ensure efficient recharging, even in emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric vehicles are deployed with existing electricity distribution infrastructure, then recharging can be done at home or at charging stations, but the limited autonomy and longer charging times compared to thermal vehicles increase the risk of breakdown due to battery discharge
Solution Approach 1:
The patent implements a peer-to-peer charging system where electric vehicle owners can offer their battery charge to other vehicles in need. This self-service mechanism allows vehicles to help each other during breakdown situations without requiring traditional charging infrastructure, thereby reducing breakdown risk while accepting limited autonomy
Solution Approach 2:
The communication network and management entity serve multiple functions: they coordinate charging requests, match vehicles needing charge with vehicles offering charge, manage authentication, and handle billing. This multi-functional system addresses the reliability issue through a versatile platform that operates without traditional charging station infrastructure
2Ease of operation
If a denser network of charging stations is deployed to compensate for lower electric vehicle range, then charging accessibility improves, but the infrastructure complexity and cost increase significantly
Solution Approach 1:
The patent introduces a communication network and management entity as intermediaries that coordinate charging between vehicles. Instead of deploying physical charging stations throughout the network, the system uses digital coordination to match charging requests with available charge sources, dramatically reducing infrastructure complexity while maintaining charging accessibility
Solution Approach 2:
The system creates a virtual replication of charging station functionality through the communication network. Rather than physically deploying numerous charging stations, the network replicates the charging service function through peer-to-peer connections, reducing infrastructure requirements while maintaining accessibility
3Reliability
If electric vehicles transfer charge between vehicles in breakdown situations, then emergency recharging is enabled, but the charge transfer is limited and takes longer than at dedicated charging stations
Solution Approach 1:
The patent acknowledges that peer-to-peer charge transfer provides only partial charging capacity compared to dedicated stations. The system is designed to handle emergency situations where partial charge transfer is sufficient to reach the nearest charging station, accepting the time penalty as a necessary trade-off for enabling emergency recharging without dedicated infrastructure

AI summary
The invention relates to a method for managing a request (DEM) to recharge a battery of an electric vehicle, carried out by a management entity (EG) capable of communicating via a communication network (NET), characterized in that it comprises a step of receiving a request (DEM) to recharge a battery of an electric vehicle issued by a client terminal (TC) associated with said electric vehicle, followed by a search step (REC), among other client terminals (TC1, TC2, TC3) associated with other electric vehicles, for client terminals capable of responding to the request (DEM) to recharge with charging proposals, and a response step (REP) including the list from the search step (REC), said response (REP) comprising a charging proposal combining several charging proposals.
