EV Charging Reservation Check-In With Vehicle ID Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles may arrive at charging stations only to find them occupied, leading to unsuccessful charging attempts.
Innovation Solution
A charging system that allows vehicles to reserve and check-in for charging, utilizing a control device to manage reservations and check-ins based on vehicle identification and payment verification, and a storage device to track charging errors, ensuring smooth charging by matching reservation and check-in information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reservation system is implemented for charging stations, then charging availability and user satisfaction are improved, but system complexity and verification requirements increase
Solution Approach 1:
The system allows users to make reservations in advance for charging stations. The control device stores reservation information including vehicle identification and timestamps, enabling users to secure charging slots before arriving at the station, thus improving charging availability and reducing wait times.
Solution Approach 2:
The control device performs collation to verify that the vehicle performing check-in matches the reserved vehicle by comparing vehicle identification information. This feedback mechanism ensures reservation authenticity and prevents unauthorized usage, maintaining system reliability while managing complexity through automated verification.
2Reliability
If vehicle identification verification is performed during check-in, then charging security is improved, but processing time and operational complexity increase
Solution Approach 1:
The vehicle's own identification information is used for verification during check-in. The control device automatically compares the vehicle's identification with the reserved identification without requiring manual intervention, enabling secure charging while minimizing processing time through automated self-verification.
3Reliability
If charging error history is tracked and displayed, then charging reliability is improved, but information processing and storage requirements increase
Solution Approach 1:
The control device generates error information based on the charging error database and presents it to the user during reservation or check-in. This feedback loop allows users to see historical error patterns for specific vehicles and charging stations, helping them make informed decisions about where to charge, thereby improving overall charging reliability.

AI summary
A charging system includes a charging station, a control device, and a storage device. The charging station charges a vehicle. The storage device stores a charging error database. The control device includes at least a processor and a memory coupled to the at one processor. The processor performs a process including: accepting check-in of the vehicle at the charging station; accepting a reservation for charging of the vehicle at the charging station; acquiring first vehicle identification information; acquiring second vehicle identification information; determining whether the first vehicle identification information matches the second vehicle identification information; permitting the check-in when the first vehicle identification information matches the second vehicle identification information; and generating error information based on the charging error database. The vehicle presents the generated error information to an occupant at the time of the reservation.
