Vehicle Battery Temperature Gradient Tracking for Charging Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery diagnostic models fail to accurately detect smaller temperature changes in vehicle batteries during charging, which can indicate potential charging issues, and do not account for gradual temperature increases that may lead to battery degradation.
Innovation Solution
A battery diagnostic tool that tracks temperature gradients over time, assigns fault values based on these gradients, and determines whether the fault values exceed a threshold, allowing for remedial actions during the charging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing vehicle battery diagnostic models are used to detect temperature changes, then the detection system is simple, but smaller temperature changes and gradual temperature increases cannot be accurately detected
Solution Approach 1:
The patent segments the temperature monitoring process into discrete time intervals, calculating temperature gradients between consecutive measurements. This segmentation allows the system to detect subtle temperature changes that would be missed by simple threshold-based monitoring, while keeping the computational complexity manageable through structured data collection and processing
Solution Approach 2:
The system performs preliminary temperature measurements at multiple time points before making diagnostic decisions. By collecting temperature data at predetermined time intervals and calculating gradients in advance, the system prepares comprehensive temperature history data that enables accurate detection of both small and gradual temperature changes when diagnostic needs arise
2Reliability
If temperature monitoring is performed continuously with high precision, then battery health diagnosis accuracy is improved, but energy consumption and measurement time increase
Solution Approach 1:
The patent implements periodic temperature measurements at predetermined time intervals during the charging process. This periodic sampling approach captures sufficient temperature gradient information to diagnose battery health reliably, while avoiding continuous monitoring that would waste time and energy. The interval-based measurement strategy balances diagnostic accuracy with operational efficiency
