Battery Degradation Factor Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide detailed information on the factors contributing to battery degradation, making it difficult for users to understand the usage patterns and factors affecting battery state changes.
Innovation Solution
A display control apparatus that acquires usage situation information, evaluates state changes, specifies contributing factors, and displays a ratio of each factor's impact on battery degradation, along with images prompting prevention of degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the degradation state of the battery is displayed, then the information presented is simple and easy to understand, but detailed information about the factors causing degradation cannot be provided
Solution Approach 1:
The patent segments the battery degradation information into multiple components: overall degradation state and individual contributing factors. The display is divided into a first area showing the degradation state and a second area showing factor information, allowing detailed information to be presented without overwhelming the user with a single complex display.
Solution Approach 2:
The patent adds a spatial dimension to the display by using multiple display areas (first area and second area) to present different types of information simultaneously. This dimensional separation allows the system to provide both simple overview information and detailed factor information without compromising either simplicity or completeness.
2Measurement precision
If detailed usage situation information is collected and analyzed, then the accuracy of degradation factor identification is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The patent extracts only the relevant degradation factor information from the comprehensive usage situation data and presents it in a simplified manner. The control device identifies specific factors (such as charge-discharge cycles, temperature conditions, etc.) from the usage data and displays only these key factors in the second area, rather than presenting all raw data.
Solution Approach 2:
The control device acts as an intermediary between the complex usage situation data and the user display. It processes the raw usage information, identifies degradation factors, and transforms them into a simplified visual representation that maintains accuracy while reducing perceived complexity for the user.

AI summary
A display control apparatus includes: an acquisition part that acquires usage situation information of a battery which stores electric power for traveling of a vehicle; an evaluation part that evaluates a state change amount of the battery based on the usage situation information acquired by the acquisition part; a specifying part that specifies one or more factors of a state change of the battery based on the usage situation information acquired by the acquisition part; and a display control part that allows a display part to display a first image indicating a ratio at which a factor of the state change contributes to the state change amount for each factor of the state change.
