Electric Vehicle Power Display Color Feedback for Green Energy Motivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective technologies that promote the use of green electric power in electric vehicles, as users are not adequately informed or motivated to utilize environmentally friendly energy sources, leading to suboptimal adoption and awareness of green energy usage.
Innovation Solution
An electric power information provision apparatus that determines whether the electric power supplied to an electric vehicle contains green energy and changes its display mode, including color, to visually indicate the use of green power, thereby motivating users and surrounding individuals to utilize green energy by providing visual recognition and assurance of environmental contribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If green electric power is used in electric vehicles, then environmental protection is promoted, but user awareness and motivation to use green energy remain insufficient
Solution Approach 1:
The patent applies color changes to the display section to indicate the type of electric power being supplied. When green electric power is detected, the display shows a first color (e.g., green); when non-green electric power is supplied, it shows a second color (e.g., red). This visual feedback mechanism increases user awareness of green power usage, motivating users to prefer green energy sources while maintaining environmental protection benefits
Solution Approach 2:
The patent implements a feedback mechanism where the display section provides real-time information about the type of electric power being supplied to the electric vehicle. The determination section detects whether green or non-green power is being used, and this information is immediately fed back to the user through color-coded display, creating awareness and encouraging green power consumption
2Ease of operation
If display information is provided to promote green power usage, then user motivation increases, but device complexity increases
Solution Approach 1:
The display section serves multiple functions: it displays the type of electric power being supplied (green or non-green), provides feedback to users to motivate green power usage, and can be integrated into existing electric vehicle interfaces. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving the goal of promoting green power usage

AI summary
A display apparatus 19 includes a display section 192 which is attached to an electric vehicle EV operable upon supply of electric power thereto and displays information regarding the electric power supplied to the electric vehicle EV; a determination section (S18) which determines whether or not the electric power supplied to the electric vehicle EV contains green electric power; and a display control section (S20, S22). In the case where the determination section (S18) determines that the electric power supplied to the electric vehicle EV contains green electric power (S18: Yes), the display control section (S20, S22) controls the display section 192 such that the display color becomes green. In the case where the determination section (S18) determines that the electric power supplied to the electric vehicle EV does not contain green electric power (S18: No), the display control section (S20, S22) controls the display section 192 such that the display color becomes red. Through recognition that the display color of the display section 192 is green, a driver of the vehicle has assurance for contribution to environmental protection through use of green electric power. Such assurance motivates the driver to use green electric power, whereby use of green electric power is promoted.
