Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery management systems for electric vehicles lack effective methods to dynamically adjust safety thresholds based on real-time data and environmental factors, leading to inadequate feedback mechanisms for ensuring battery safety and efficiency.
Innovation Solution
A battery management method that calculates safety based on physical quantity data, monitors threshold adjusting events, and adjusts safety thresholds using reference information, including user preferences, use patterns, environmental conditions, and accident history, to generate feedback signals for visual, auditory, or tactile alerts when safety thresholds are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed safety thresholds are used in battery management systems, then the system structure is simple and easy to implement, but the system cannot adapt to changing environmental conditions and usage patterns, leading to reduced reliability
Solution Approach 1:
The patent implements dynamic threshold adjustment by continuously monitoring environmental parameters (temperature, humidity), usage patterns (charging cycles, discharge rates), and battery state (voltage, current) to automatically modify safety thresholds. This allows the system to adapt to changing conditions in real-time, improving reliability without requiring manual intervention or complex reconfiguration
Solution Approach 2:
The battery management system performs self-adjustment of safety thresholds based on embedded sensors and pre-programmed algorithms. The system autonomously evaluates multiple parameters and modifies thresholds without external input, reducing the need for complex external control mechanisms while maintaining high reliability
2Measurement precision
If multiple environmental and usage parameters are monitored to adjust safety thresholds, then the accuracy of battery state monitoring is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent combines multiple monitoring functions into a unified battery management system that simultaneously tracks environmental conditions, usage patterns, and battery state. By integrating these functions into a single system with centralized processing, the patent achieves high measurement accuracy without proportionally increasing device complexity
Solution Approach 2:
The monitoring system is designed to handle multiple types of data (temperature, voltage, current, charging cycles, discharge rates) using a universal processing framework. This multi-functional approach allows the system to accurately monitor diverse parameters through a single integrated mechanism rather than requiring separate systems for each parameter
3Reliability
If real-time feedback is provided to users when safety thresholds are exceeded, then user awareness of battery safety is improved, but the frequency of feedback signals may cause user alarm or desensitization
Solution Approach 1:
The patent implements differentiated feedback strategies based on the specific threshold violated and the severity of the condition. Different feedback types (visual, auditory, haptic) are applied to different situations, with intensity and frequency adjusted to the specific safety concern. This localized approach ensures effective communication of safety issues without causing unnecessary user alarm
Solution Approach 2:
The system provides continuous feedback to users about battery safety status through multiple channels (display screens, audio alerts, vibration motors). The feedback mechanism is designed to inform users of threshold violations while providing context about the nature and severity of the issue, enabling appropriate user response without causing panic or desensitization

AI summary
Disclosed is a battery management method including calculating a safety of a battery unit based on physical quantity data of the battery unit, monitoring for a threshold adjusting event to occur, performing a comparing with respect to the calculated safety and a threshold based on the monitoring indicating that the threshold adjusting event has occurred, the comparing being based on reference information corresponding to the threshold adjusting event, and selectively performing a feedback process to output a feedback dependent on a result of the comparison.
