Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately determining the cause of battery deterioration in secondary batteries is challenging, even when the degree of deterioration is measured, making it difficult to implement effective measures to suppress deterioration.
Innovation Solution
A presentation device and method that acquire and analyze the usage status of secondary batteries across multiple vehicles, deriving representative values and presenting advice on how to suppress deterioration based on comparative data, allowing users to recognize and address specific usage factors contributing to battery degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the degree of deterioration of a secondary battery is accurately determined, then the measurement precision of battery status is improved, but the ability to identify the cause of deterioration and recognize usage patterns remains insufficient
Solution Approach 1:
The patent transitions from one-dimensional deterioration degree measurement to multi-dimensional analysis by incorporating usage status information (charging/discharging cycles, temperature, load conditions) as additional dimensions. This allows comprehensive derivation of deterioration causes by analyzing relationships between multiple parameters rather than relying solely on deterioration degree measurement.
Solution Approach 2:
The patent introduces usage status information as an intermediary element that connects the measured deterioration degree to the underlying causes. By acquiring and analyzing usage status data (charging patterns, temperature history, load conditions), the system can infer deterioration causes that would otherwise be inaccessible through direct measurement alone.
2Adaptability or versatility
If representative values are derived from multiple vehicles to provide comparative data, then the usefulness of deterioration suppression advice is improved, but the device complexity increases due to data acquisition and processing requirements
Solution Approach 1:
The patent creates a multi-functional system where the presentation device not only displays individual battery status but also performs comparative analysis across multiple vehicles, generates deterioration suppression advice, and provides a comprehensive diagnostic tool. This universal approach consolidates multiple functions into one integrated system, improving versatility while managing complexity through unified design.
Solution Approach 2:
The system enables users to automatically obtain comparative data and deterioration suppression advice without requiring manual data collection or complex external analysis. By automatically acquiring usage status information from multiple vehicles and generating personalized advice, the system serves itself and the user simultaneously, reducing the operational complexity burden on the user.
3Productivity
If usage status information of multiple vehicles is acquired and analyzed, then the productivity of deterioration diagnosis is improved, but the loss of time for data collection and processing increases
Solution Approach 1:
The patent implements preliminary action by continuously acquiring and storing usage status information from multiple vehicles in advance. This pre-collected data is then readily available for immediate comparative analysis and deterioration diagnosis, eliminating the need for time-consuming data collection at the moment of diagnosis and significantly improving diagnostic productivity.
