Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery management system monitors battery health status in real time, then driving safety is improved, but the accuracy of health status evaluation is insufficient
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the battery management system and the evaluation process. The cloud server receives battery data from the vehicle, performs comprehensive analysis using multiple parameters (temperature, voltage, current, historical data), and generates accurate health status evaluations. This intermediary enables complex processing that enhances measurement precision without burdening the real-time vehicle system.
Solution Approach 2:
The patent transitions from single-dimension real-time monitoring to multi-dimensional evaluation by incorporating historical battery data, environmental conditions, charging patterns, and multiple electrical parameters. This dimensional expansion allows for much more accurate health status assessment through comprehensive data analysis.
2Measurement precision
If multiple parameters are collected for battery evaluation, then evaluation accuracy is improved, but data management complexity increases
Solution Approach 1:
The patent extracts the complex data management and analysis functions from the vehicle's battery management system and relocates them to a cloud server. The vehicle system only needs to collect and transmit raw data, while the cloud server handles the complex processing, storage, and analysis of multiple parameters, significantly reducing on-vehicle data management complexity.
Solution Approach 2:
The cloud server is designed as a universal platform that can handle multiple battery types, different vehicle models, and various evaluation scenarios. This multi-functional approach simplifies data management by providing a standardized processing framework that accommodates diverse battery data without requiring complex vehicle-specific management systems.
