Vehicle Charging Display Control for Clear Time Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle control devices display complex and potentially misreadable times for battery charging, failing to provide a simple and user-friendly indication of the necessary time to reach full charge or a predetermined charge state.
Innovation Solution
An in-vehicle control device that switches between displaying a first necessary charging time to reach a predetermined storage proportion and a second necessary charging time to reach full charge, based on predefined conditions or user interactions, using a processor to output these times to a display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both the necessary time to reach full charge and the necessary time to reach a predetermined charge state are displayed, then the user can check multiple charging scenarios, but the displayed contents become complex and may be misread by the user
Solution Approach 1:
The display dynamically changes between showing the first necessary charging time (to predetermined charge state) and the second necessary charging time (to full charge) based on the current charge state of the power storage device. When the charge state is below the predetermined threshold, the display shows the first necessary charging time; when the charge state reaches or exceeds the threshold, it switches to showing the second necessary charging time. This dynamic switching resolves the contradiction by adapting the display content to the current charging stage, providing relevant information without overwhelming the user with both times simultaneously.
2Adaptability or versatility
If the necessary time to reach full charge is displayed, then the user can plan charging duration, but some users may desire to display just one type of charging time information
Solution Approach 1:
The display adapts its content based on the charging stage rather than requiring user configuration, automatically showing the first necessary charging time when the charge state is below the predetermined proportion and switching to the second necessary charging time when the charge state reaches or exceeds the threshold. This dynamic adaptation provides different charging time information at different stages without requiring user intervention, resolving the contradiction between versatility and simplicity by making the system adaptive to charging progress rather than user preferences.

AI summary
An in-vehicle control device, configured to control charging of a power storage device that is installed in a vehicle, includes a processor. The processor is configured to output a first necessary charging time to a display device when a predetermined condition is satisfied while charging the power storage device. The first necessary charging time is an amount of time required for a storage proportion of the power storage device to reach a predetermined storage proportion that is lower than a full-charge proportion. The processor is configured to output a second necessary charging time to the display device when the predetermined condition is not satisfied while charging the power storage device. The second necessary charging time is an amount of time required for the storage proportion of the power storage device to reach the full-charge proportion.
