Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems lack efficient methods to track and manage the deterioration of components within battery stations, leading to potential anomalies and increased maintenance costs due to unbalanced deterioration rates among slots.
Innovation Solution
An information acquisition device and system that tracks the number of attachments and detachments between power storage devices and electrical power devices, estimating deterioration degrees to prioritize maintenance and component replacement based on usage data, ensuring balanced deterioration rates and reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of attachment/detachment operations is increased to improve battery utilization, then productivity is improved, but the deterioration of terminals accelerates, reducing reliability
Solution Approach 1:
The system performs preliminary actions by detecting attachment/detachment operations and estimating deterioration degrees before critical failures occur. The counting units track usage from the outset, and the estimation units continuously assess terminal conditions, enabling proactive maintenance scheduling that prevents reliability degradation while maintaining high productivity
Solution Approach 2:
The system establishes feedback loops where deterioration information from estimation units feeds back to the selection and lending units. This feedback mechanism allows the system to adjust battery assignment strategies based on real-time terminal conditions, optimizing the balance between utilization and reliability by redirecting high-usage batteries to less critical applications or scheduling maintenance before deterioration becomes problematic
2Reliability
If maintenance is performed frequently to maintain reliability, then reliability is improved, but loss of time and productivity decrease
Solution Approach 1:
The system changes the parameter of maintenance timing from fixed schedules to condition-based timing. By continuously monitoring attachment/detachment counts and estimating deterioration degrees, the system dynamically adjusts maintenance schedules based on actual usage patterns and terminal conditions, performing maintenance only when deterioration reaches predetermined thresholds, thus minimizing downtime while maintaining reliability
Solution Approach 2:
The system performs preliminary assessment of terminal deterioration through estimation units before maintenance is actually needed. This allows planning and scheduling of maintenance activities in advance during low-utilization periods, reducing the impact on productivity while ensuring reliability is maintained through timely interventions
3Ease of operation
If uniform maintenance schedules are applied to all battery slots, then ease of operation is improved, but unbalanced deterioration rates cause some slots to deteriorate faster, reducing reliability
Solution Approach 1:
The system applies local quality by assigning different maintenance schedules to different battery slots based on their specific usage patterns and deterioration rates. The selection unit tracks attachment/detachment operations for each slot individually, and the estimation unit assesses deterioration specific to each terminal, enabling customized maintenance planning that addresses local conditions rather than applying uniform schedules, thus maintaining reliability across all slots while remaining operationally manageable
