Contactless Charging Gate Control for Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In contactless charging systems, normal vehicles can occupy parking spaces intended for contactless charged vehicles, making it difficult to confirm if a vehicle is charged and leading to inefficient use of power transmission devices, as the system cannot distinguish between charged and uncharged vehicles, resulting in wasted opportunities for contactless charging and fee collection.
Innovation Solution
A contactless charging system with a management device that controls restriction devices to permit or restrict entry based on whether a vehicle is a contactless charged vehicle, ensuring that only contactless charged vehicles use parking spaces equipped with power transmission devices, and utilizing external server information to optimize parking space allocation based on predicted usage rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entrance gate is opened to permit entry of target vehicles without verification, then the ease of operation is improved, but the parking spaces are occupied by normal vehicles instead of contactless charged vehicles
Solution Approach 1:
The system uses the vehicle's own communication device to automatically transmit identification information to the management device, enabling automatic recognition and classification without manual intervention. Contactless charged vehicles self-identify through their communication capabilities, allowing the system to distinguish them from normal vehicles and allocate parking spaces accordingly.
Solution Approach 2:
The management device receives feedback from the vehicle's communication device regarding its contactless charging capability. This feedback mechanism allows the system to adjust the entrance gate control and parking space allocation based on the vehicle type, ensuring that contactless charged vehicles are directed to appropriate spaces while normal vehicles are guided elsewhere.
2Productivity
If the entrance gate is restricted to only contactless charged vehicles, then the usage efficiency of parking spaces is improved, but the ease of operation deteriorates due to verification requirements
Solution Approach 1:
The system replaces manual verification mechanisms with automatic wireless communication-based identification. Instead of requiring operators to physically verify vehicle types or manually check credentials, the system uses the vehicle's communication device to automatically transmit and process identification information, substituting mechanical verification with electronic automation.
Solution Approach 2:
The vehicle's communication device automatically performs the identification function by transmitting its own contactless charging capability information to the management device. This self-service approach eliminates the need for external verification personnel or complex manual checking processes, maintaining ease of operation while ensuring accurate vehicle classification.
3Ease of operation
If normal vehicles are permitted to use parking spaces, then the ease of operation is improved, but the contactless power transmission devices cannot be used by contactless charged vehicles
Solution Approach 1:
The parking area is segmented into different zones: parking spaces equipped with contactless power transmission devices and other parking spaces. The management device controls the entrance gate to direct contactless charged vehicles to the appropriate segmented area, while normal vehicles are directed to other spaces. This spatial segmentation ensures that each vehicle type accesses the facilities suitable for its needs, preventing conflicts and ensuring reliable availability of power transmission devices.
4Device complexity
If the system cannot distinguish between contactless charged vehicles and normal vehicles, then the device complexity is reduced, but the loss of information regarding vehicle type occurs
Solution Approach 1:
The management device acts as an intermediary that receives communication signals from vehicles and determines their type based on the transmitted information. This intermediary function allows the system to maintain relative simplicity while accurately acquiring vehicle type information through the communication device, bridging the gap between simple hardware and informed decision-making.
Solution Approach 2:
The communication device provides feedback information about the vehicle's contactless charging capability to the management device. This feedback loop enables the system to distinguish between vehicle types without adding complex verification hardware, as the vehicle itself provides the necessary identification information through its communication system.

AI summary
A contactless charging system (1) includes a target vehicle and a charging station (20; 20A). The charging station (20; 20A) includes a power transmission device (26a, 26b, 26c, 26d, 26e), at least one parking space (PSa, PSb, PSc, PSd, PSe), a restriction device (28a, 28b, 28c, 28d, 28e), and a management device (22; 22A). The management device (22; 22A) is configured to control the restriction device (28a, 28b, 28c, 28d, 28e) to be a second state in which the target vehicle is permitted to enter the charging station and the parking space when the target vehicle is the contactless charged vehicle (10), and to be a first state in which the target vehicle is restricted to enter the charging station or the parking space when the target vehicle is not the contactless charged vehicle.
