EV Charger Compatibility Management for Charging Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for electric vehicles face compatibility issues leading to charging troubles such as failure in normal start of charging, delay, and other electrical compatibility failures, which existing technologies fail to address, and result in incomplete charging history information accumulation.
Innovation Solution
A charger management device and charging control device that acquire and store charging status information, including vehicle and charger information, to generate compatibility information, identify potential charging errors, and distribute compatibility information to vehicles, preventing charging troubles by avoiding incompatible chargers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If DC chargers are used for quick charging, then charging speed is improved, but compatibility issues cause charging troubles such as failure to start and delays
Solution Approach 1:
The system performs preliminary compatibility verification between the vehicle and external charger before initiating charging. The charging control device checks compatibility information in advance, and if incompatibility is detected, it prevents charging from starting or terminates it if already running, thereby avoiding charging troubles while maintaining quick charging capability
Solution Approach 2:
The system establishes a feedback mechanism where charging status information is continuously monitored and communicated between the vehicle and charging management server. Compatibility issues are detected through feedback loops during the charging process, allowing the system to respond to and resolve compatibility problems that arise during quick charging operations
2Reliability
If compatibility verification is performed before charging, then charging troubles are avoided, but additional information processing is required
Solution Approach 1:
A charging management server acts as an intermediary between the vehicle and external charger, handling compatibility verification and information management. The server stores compatibility information and coordinates communication between charging parties, reducing the complexity burden on individual charging devices while ensuring reliable compatibility checking
Solution Approach 2:
The charging management server provides multiple functions including compatibility verification, information storage, communication coordination, and charging status monitoring. By consolidating these diverse functions into a single universal platform, the system avoids the need for each device to independently handle all compatibility checks, thereby managing complexity efficiently
3Loss of information
If charging status information is collected and stored, then compatibility issues can be identified, but data management complexity increases
Solution Approach 1:
The system merges charging status information collection, compatibility data storage, and analysis functions into an integrated charging management server. By combining these data management tasks into a single centralized system rather than distributing them across multiple devices, the solution reduces overall data management complexity while ensuring comprehensive information retention for compatibility verification

AI summary
A charger management server manages compatibility between an external charger and a vehicle. The server includes an information acquisition unit that acquires charging status information on a status acquired when the external charger and the vehicle are connected to conduct charging, and a compatibility information generation unit that generates compatibility information on compatibility between the external charger and the vehicle based on the charging status information. The server also includes a charger management database storing the charging status information and the compatibility information. As the charging status information, the information acquisition unit acquires vehicle information on the vehicle, charger information on the external charger connected with the vehicle, and charging error information on a charging error caused between the external charger and the vehicle.
