Charging Station Diagnostics Using Vehicle Battery Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated storage and retrieval systems, when a charger fails due to a power supply issue, the system cannot accurately communicate diagnostic errors to the central control system, leading to generic communication failure classifications that do not provide sufficient guidance for resolving the issue.
Innovation Solution
The system includes a control system that detects charger failures, instructs a vehicle to move to the charging station, and uses the vehicle's power storage source to enable the charger to transmit diagnostic information to the central controller, allowing for specific error identification and guidance for the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging station uses external power supply, then it can charge vehicles, but it cannot transmit diagnostic information when power supply fails
Solution Approach 1:
The charging station is equipped with a backup power storage source (battery) that is activated beforehand when external power supply fails. This backup power source ensures that the charging station can maintain its diagnostic communication function even when the primary power supply fails, thus cushioning against the loss of diagnostic information.
Solution Approach 2:
The vehicle's power storage source acts as an intermediary to provide power to the charging station when external power supply fails. This intermediary power source enables the charging station to transmit diagnostic information to the central control system, solving the problem of information loss during power supply failures.
2Ease of operation
If the system classifies charger errors as communication failures, then it simplifies error handling, but it loses precision in diagnosing the actual problem
Solution Approach 1:
The charging station transmits diagnostic information back to the central control system using the vehicle's power storage source. This feedback mechanism provides precise information about the actual charger status and errors, enabling accurate diagnosis while maintaining simple error handling procedures through automated information transmission.
3Adaptability or versatility
If the charging station remains stationary, then it serves fixed charging points, but it cannot actively diagnose issues without power
Solution Approach 1:
The charging station utilizes the vehicle's own power storage source to power its diagnostic communication function. This self-service approach allows the stationary charging station to actively diagnose and report issues even when external power is unavailable, maintaining diagnostic reliability while serving fixed charging points.
