Battery Error History Display Using Related State Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques only highlight the abnormal item in a battery's operation history, making it difficult for managers to determine the type of error that has occurred and understand its cause.
Innovation Solution
An information processing method that acquires and displays the operation history of both the abnormal state item and related state items, allowing users to determine the type of error by viewing the histories of both.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the abnormal state item is displayed in a highlighted manner, then the display is simple and focused, but the user cannot determine the type of error or understand its cause
Solution Approach 1:
The display is segmented into two distinct parts: the abnormal state item display area showing only the abnormal item in a highlighted manner, and the operation history display area showing the temporal changes of related state items. This segmentation allows the system to provide comprehensive error determination information while maintaining a clean, focused interface that doesn't overwhelm the user with all data at once.
Solution Approach 2:
The patent adds a temporal dimension to the display by showing operation history over time. Instead of only displaying static abnormal values, the system presents how state items have changed temporally, enabling users to understand the progression and cause of errors through historical trends rather than isolated snapshots.
2Loss of information
If the operation history of all state items is displayed, then the user can determine error type, but the processing load and data volume increase
Solution Approach 1:
The system extracts and displays only the operation history of state items that are related to the selected abnormal state item, rather than displaying all state items. This extraction is achieved through a related state item determination module that identifies which state items have causal or correlational relationships with the abnormal item, thereby reducing data volume while preserving error determination capability.
Solution Approach 2:
The display provides detailed operation history information locally for specific related state items that are relevant to the abnormal condition, rather than uniformly displaying all state items. This local quality approach ensures that comprehensive error analysis information is available where needed (for related items) while avoiding unnecessary data display for unrelated items.

AI summary
An information terminal acquires a plurality of abnormal state items indicating a state item for which an abnormal value is detected from among a plurality of state items indicating a plurality of states of a plurality of batteries, upon receiving selection of one abnormal state item of one battery among the plurality of abnormal state items having been acquired, acquires a related state item indicating a state item related to the one abnormal state item having been selected from among the plurality of state items of the one battery, and displays an operation history of the related state item having been acquired.
