Solution Overview

Problem

In electric vehicle charging stations, vehicles may unexpectedly wait for chargers due to other vehicles cutting in front of them, leading to inefficient charging processes.

Innovation Solution

A control device is implemented that acquires identification information for vehicles entering the charging station, associates this information with available chargers, and permits charging only when the vehicle's identification information matches the associated charger, preventing cutting in line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vehicles are allowed to freely use available chargers in the charging station, then charger utilization is improved, but unexpected waiting occurs due to vehicles cutting in front of others

Engineering Contradiction:
Improvecharger utilizationVSAvoidunexpected waiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The control device performs preliminary actions by acquiring identification information of vehicles before they enter the charging station, determining their charging eligibility in advance, and establishing a charging order. This preliminary organization prevents vehicles from cutting in line and reduces unexpected waiting time while maintaining efficient charger utilization.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If a control system is implemented to manage vehicle-charger association, then charging order is improved, but device complexity increases

Engineering Contradiction:
Improvecharging order managementVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control device automatically performs vehicle identification, eligibility determination, and charger association without requiring manual intervention from vehicle operators. The system manages the charging order autonomously by processing identification information and controlling charger access, thereby improving charging order management while keeping the operational interface simple for users.

Inventive Principle:
Principle #25Self-service

AI summary

A control device includes one or more processors and one or more memories coupled to the one or more processors. The one or more processors are configured to execute processing. The processing includes: acquiring identification information for identifying a vehicle that is to enter a charging station; associating the identification information with a charger among chargers located in the charging station; and permitting a battery of the vehicle identified by the identification information to be charged using the charger with which the identification information is associated.
