EV Charging Pile Matching by Location and Engagement Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric vehicles face cumbersome and time-consuming processes when charging, as there is no direct communication channel between the vehicle and the charging pile, requiring manual scanning of two-dimensional codes to match the vehicle with the correct charging pile.
Innovation Solution
A method and apparatus for determining a charging device engaged with a vehicle, involving selection of primary and secondary candidate charging devices based on geographic location and operating status, using historical and real-time data to automate the matching process, allowing 'plug and charge' functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scanning of two-dimensional code is used to match vehicle with charging pile, then the charging process can be initiated, but the operation becomes troublesome and time-consuming for users
Solution Approach 1:
The charging pile automatically performs identification and matching with the vehicle using its identification module and processing module, eliminating the need for manual code scanning by the user. The system serves itself by autonomously determining the vehicle model, battery capacity, and charging parameters through communication with the vehicle's control unit.
Solution Approach 2:
The manual mechanical operation of scanning and entering codes is replaced by an automated electronic identification system. The charging pile uses its identification module to automatically detect and communicate with the vehicle's control unit, substituting the manual scanning process with electronic data exchange and automated parameter matching.
2Loss of information
If no communication channel exists between vehicle and charging pile, then the charging infrastructure remains simple, but it is impossible to inform the application of the electric vehicle of which specific charging pile is to be used
Solution Approach 1:
The vehicle's control unit acts as an intermediary that receives identification information from the charging pile's identification module and processes the matching logic. This intermediary approach allows information exchange without requiring a complex direct communication channel between all system components, simplifying the overall system architecture while enabling automated identification.
3Productivity
If automated identification is implemented using geographic location and operating status, then the matching process becomes efficient and automatic, but the system requires access to and processing of historical and real-time data
Solution Approach 1:
The system pre-establishes a database of vehicle information including battery capacity, power requirements, and charging characteristics. When a vehicle approaches the charging pile, the identification module quickly retrieves relevant data from this pre-prepared database and compares it with the vehicle's actual parameters, enabling rapid automated matching without complex real-time calculations.

AI summary
A method for determining a charging device that is being physically engaged with a vehicle in interest includes, after the charging device is physically engaged with the vehicle in interest, at least one primary candidate charging device is selected based on a current geographic location of the vehicle in interest and, from the at least one primary candidate charging device, a secondary candidate charging device that is possibly being engaged with the vehicle in interest is selected type by type according to screening conditions that vary with the type of the charging device, where the type of the charging device is determined based on an ability of the charging device in expressing that the charging device is in a status of being physically engaged but not activated to charge.
