Vehicle Charging Display with Environmental Load Breakdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging systems lack the ability to inform users about the environmental impact of their energy sources, making it difficult to promote environmentally friendly energy use.
Innovation Solution
A display control device that acquires power source information, derives an environmental load level, and displays this information alongside battery levels, using different colors and indicators to visually represent the environmental impact of the energy used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If charging systems provide basic battery level information, then users can monitor charging status, but users cannot understand the environmental impact of different power sources
Solution Approach 1:
The battery level is segmented into multiple components, each representing different power sources (renewable energy, grid power, etc.). Each segment is displayed with distinct visual characteristics (colors, icons) to represent its environmental impact, allowing users to see both the overall charge level and the environmental composition simultaneously
Solution Approach 2:
Different colors are assigned to represent different power sources and their environmental impacts. For example, green may represent renewable energy while yellow or red represents conventional power sources. This color-coding system provides intuitive environmental information without adding complex displays
2Loss of information
If the system displays detailed power source breakdown information, then users can make environmentally conscious choices, but the information becomes difficult to interpret intuitively
Solution Approach 1:
Each power source type is assigned a distinctive color that reflects its environmental characteristics. The display uses these colors to create an intuitive visual language where users can immediately understand the environmental quality of different power sources without needing to read detailed explanations
Solution Approach 2:
The system adds a visual dimension (color, iconography) to represent environmental impact, transforming abstract power source data into perceptible visual information. This dimensional transformation makes complex information accessible at a glance
3Loss of information
If the system provides comprehensive charging history and power source data, then environmental accountability is improved, but users cannot easily understand current environmental load
Solution Approach 1:
The charging history is segmented into discrete power source events, each tagged with environmental characteristics. This segmentation allows the system to aggregate and analyze environmental impact over time while presenting simplified summaries to users, showing both detailed history and current status

AI summary
According to an embodiment, a display control device includes an acquirer configured to acquire information including source information of power that is supplied when a battery mounted in a vehicle is charged, a deriver configured to derive an environmental load level that is an influence level of an environmental load of the power with which the battery is charged on the basis of the source information acquired by the acquirer, and a display controller configured to cause a display to display an image in which the environmental load level derived by the deriver is associated with a breakdown of a battery level.
