Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle battery diagnosis systems do not effectively communicate actionable measures to users for extending the service life of rechargeable batteries used as motive power sources in electric and hybrid motor vehicles, despite recognizing time-dependent degradation influenced by driving patterns and environmental factors.
Innovation Solution
A vehicle battery diagnosis system that accumulates diagnostic information, presents control plans to users, dealers, and manufacturers for optimizing battery usage, and changes vehicle control parameters to prolong battery life, including adjustable parameters for regenerative braking, temperature management, and charging strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional vehicle diagnosis systems are applied to batteries, then diagnostic information can be obtained, but users cannot understand what measures to take to extend battery service life
Solution Approach 1:
The patent introduces an intermediary system that translates raw diagnostic battery data into comprehensible service life extension recommendations. This intermediary layer processes technical diagnostic information and presents it in a user-friendly format with actionable measures, bridging the gap between diagnostic capability and user understanding.
Solution Approach 2:
The system enables users to independently understand and implement battery maintenance measures by providing clear, actionable guidance based on diagnostic results. Users can self-manage their battery service life through the presented control plans without requiring specialized knowledge or external assistance.
2Duration of action of stationary object
If battery service life is extended through optimized control, then battery degradation is reduced, but vehicle performance may be compromised
Solution Approach 1:
The system dynamically adjusts control parameters based on the selected service life extension plan. By making control information changeable and adaptable, the system can optimize between battery longevity and vehicle performance according to user preferences and battery condition, rather than using fixed restrictive parameters.
Solution Approach 2:
The patent changes control parameters related to battery charging and discharging to extend service life. By systematically adjusting these parameters and presenting multiple control plans with different parameter settings, the system allows optimization of both battery durability and vehicle performance through informed selection.
3Ease of operation
If multiple control plans are presented to users, then informed decisions can be made, but system complexity increases
Solution Approach 1:
The patent segments the battery control strategy into multiple distinct control plans, each with specific characteristics and benefits. This segmentation allows users to choose from predefined options rather than navigating a continuous complex parameter space, simplifying the decision-making process while maintaining system sophistication.

AI summary
A vehicle battery diagnosis system diagnoses the state of use of a battery of a vehicle, and includes: an information accumulation portion that accumulates diagnostic information that includes a use condition regarding the battery; a control plan presentation portion that presents a plurality of control plans about the vehicle for increasing the service life of the battery on the basis of the diagnostic information; and an information changing portion that changes control information regarding the control of the vehicle which is retained in a vehicle-mounted ECU of the vehicle so that the control information corresponds to a control plan selected from the plurality of control plans.
