EV Charging Map Guidance Using Predicted Battery Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guidance systems for electric vehicles struggle to visually convey the recovery amount of the battery state of charge when using different charging facilities.
Innovation Solution
A guidance apparatus that acquires the current position of a vehicle, extracts nearby charging facilities, predicts the recovery amount of the battery state of charge based on charging time, and varies the display form of the charging facilities on a map according to the predicted recovery amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional guidance systems display charging facilities, then users can locate charging facilities, but users cannot visually grasp the recovery amount of battery state of charge
Solution Approach 1:
The patent applies color changes to icons representing charging facilities to visually indicate the predicted recovery amount of battery state of charge. Different colors or color intensities correspond to different recovery amounts, enabling users to immediately grasp charging effectiveness without additional text or data processing.
Solution Approach 2:
The patent adds a visual dimension (color intensity or size variation) to the display of charging facility icons, transforming the representation from a two-dimensional static icon to a multi-dimensional visual indicator that encodes recovery amount information.
2Loss of information
If the system provides detailed charging information, then users can make informed decisions, but the display becomes complex and hard to interpret
Solution Approach 1:
Instead of displaying complex numerical data and text descriptions, the system uses color variations on icons to represent charging information, simplifying the display while preserving the essential information about recovery amounts.
Solution Approach 2:
The patent segments charging facility information into distinct visual elements (icons with color indicators), separating the essential recovery amount information from other charging facility details, allowing users to quickly identify the most relevant information.

AI summary
A guidance apparatus is for guidance to a charging facility and includes a positional information acquisition interface, a display and a controller. The positional information acquisition interface is configured to acquire information on the current position of a mobile object. The display is configured to display the charging facility. The controller is configured to extract a charging facility located within an area based on the current position, predict a recovery amount of a state of charge of a battery of the mobile object, expressed as a charging rate relative to a full charge of the battery, in a case in which the battery is charged at the charging facility for a predetermined charging time, and vary a display form of the charging facility displayed on a map image, according to a predicted value of the recovery amount of the state of charge.
