Vehicle Battery Diagnosis System with Tailored Display Formats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle battery diagnosis systems fail to provide tailored information to different stakeholders, such as manufacturers, dealers, and users, and do not effectively manage the service life and replacement planning of batteries in vehicles equipped with batteries as motive power sources, especially in plug-in hybrid vehicles where battery degradation is accelerated.
Innovation Solution
A vehicle battery diagnosis system that accumulates degradation information, processes it to create multiple types of screen information for various recipients, and displays relevant data, including unit degradation, remaining service life, replacement plans, costs, and delivery times, allowing users and dealers to make informed decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display format is used for all information recipients, then the device complexity is reduced, but the information cannot be tailored to different needs of manufacturers, dealers, and users
Solution Approach 1:
The display information is segmented into multiple formats: a first format showing only the replacement timing division (good/intermediate/bad) for general users, and a second format showing detailed degradation data for professionals. This segmentation allows each recipient type to receive appropriately tailored information without increasing overall system complexity.
Solution Approach 2:
The display format is made dynamic by allowing switching between the first simplified format and the second detailed format. The system automatically or manually adjusts the display complexity based on the recipient's needs, enabling adaptability without requiring multiple fixed display systems.
2Loss of information
If detailed degradation information is provided to all users, then manufacturers and dealers get the information they need, but regular users are overwhelmed with unnecessary technical data
Solution Approach 1:
Different information quality levels are provided to different recipient groups. Regular users receive simplified information focused on replacement timing decisions, while manufacturers and dealers receive comprehensive degradation data. This local quality differentiation ensures each group gets the appropriate level of detail without information overload or deficiency.
Solution Approach 2:
The system provides partial information (only replacement timing) to regular users who need simple decision-making support, and excessive information (all degradation details) to professionals who require comprehensive data. This partial/excessive action approach optimizes information delivery based on recipient needs.
3Use of energy by moving object
If the battery is charged to full capacity frequently to reduce fuel consumption, then energy efficiency is improved, but the battery service life is reduced due to accelerated degradation
Solution Approach 1:
The system provides feedback to users about the intermediate division state of the battery, indicating when full charging should be avoided. By monitoring degradation trends and communicating this information to users, the system enables them to make informed charging decisions that balance fuel efficiency with battery longevity.
Solution Approach 2:
The system estimates future replacement timing based on current degradation trends and communicates this information in advance to users. This preliminary action allows users to plan their charging behavior proactively, avoiding patterns that would accelerate degradation while still maintaining acceptable fuel efficiency.
Data Source
AI summary
A vehicle battery diagnosis system diagnoses the state of degradation of a battery of a vehicle equipped with the battery as a motive power source. The system includes: an information accumulation portion that accumulates degradation information regarding the battery; an information processing portion that reads information from the information accumulation portion, and that creates a plurality of types of screen information that are different from each other in display format, for a plurality of information recipients; a display portion that displays a screen that corresponds to at least one of the types of screen information created by the information processing portion.
