EV Charging Activation via Session ID Verification

Solution Overview

Problem

The widespread adoption of electric vehicles is hindered by the lack of suitable charging infrastructure, leading to concerns about running out of charge in locations where recharging is not possible.

Innovation Solution

A method and apparatus that utilize a charging activation system to verify and authorize charging sessions by comparing charging session IDs from the vehicle's electricity provider and the connected power outlet's provider, ensuring secure and efficient charging through existing power grid infrastructure without requiring modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electric vehicles are equipped with charging capabilities, then the ability to recharge is improved, but the risk of running out of charge in locations without charging infrastructure increases

Engineering Contradiction:

Improverecharging capabilityVSAvoidcharge availability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The charging system is designed to work with multiple types of power outlets and electricity providers simultaneously. The vehicle can charge from standard electrical outlets, dedicated charging stations, and various power grid infrastructures, making the charging capability universal and applicable in diverse locations without requiring specialized infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

A communication and verification system acts as an intermediary between the vehicle, power outlets, and electricity providers. This intermediary verifies charging session IDs and coordinates between different providers, enabling seamless charging across multiple infrastructure types while maintaining reliability through centralized verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a charging verification system comparing session IDs from multiple providers is implemented, then charging security and accuracy are improved, but the complexity of the charging activation system increases

Engineering Contradiction:

Improvecharging authorization accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary verification of charging session IDs before activating charging. By comparing the session ID from the vehicle's electricity provider with the session ID from the power outlet's provider in advance, the system ensures authorization accuracy before charging begins, preventing unauthorized or incorrect charging sessions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verification system implements feedback loops where charging session information is continuously monitored and verified. The system compares session IDs, provides feedback on authorization status, and adjusts charging activation accordingly, ensuring accurate authorization while maintaining manageable complexity through automated feedback mechanisms.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If charging can be activated from any power outlet, then the versatility of charging locations is improved, but the difficulty of managing multiple electricity providers increases

Engineering Contradiction:

Improvecharging location flexibilityVSAvoidprovider coordination complexity

Core Design Contradiction:

AI summary

A method in which a charging activation apparatus associated with an electric vehicle (i) receives a first instance of a charging session ID from first server apparatus associated with a first electricity provider which is the electricity provider of a driver or owner of the electric vehicle; (ii) receives a second instance of the charging session ID from second server apparatus associated with a second electricity provider which is the electricity provider for a power outlet with which the electric vehicle is currently electrically connected; (iii) compares the first and second instances of the charging session ID; (iv) determines if the first and second instances of the charging session ID correspond; and, if the first and second instances of the charging session ID are determined to correspond, (v) causes activation of charging of the electric vehicle via the electrical connection to the power outlet.
