Battery Module Processor for Cell Status Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery module systems for vehicles, such as aircraft, face challenges in efficiently managing and verifying the status of battery cells, including state of charge, capacity, and health, particularly when dealing with different cell chemistries, and ensuring compatibility and compliance with mission and regulatory requirements.
Innovation Solution
A battery module system comprising a battery module processor that receives cell signals (temperature, voltage, or current) to determine cell status and communicate it to a master/module interface, which can connect to multiple battery modules, verify compatibility, and deliver power only when predefined requirements are met, using a battery master system to manage and disconnect power as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery module system manages multiple cells with different chemistries, then the system's versatility and adaptability improve, but the complexity of managing and verifying cell status increases
Solution Approach 1:
The system divides the battery management into modular components: individual battery modules each with their own processor that independently monitors cell status, and a master processor that coordinates verification. This segmentation allows different cell chemistries to be managed in isolated units, reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The master/module interface acts as an intermediary between individual battery modules and the master processor. It standardizes communication protocols and data formats, allowing modules with different cell chemistries to interface uniformly with the management system, thereby reducing complexity while supporting diversity.
2Reliability
If the system verifies status information from multiple battery modules before power delivery, then reliability and compliance improve, but the time required for verification increases
Solution Approach 1:
The system performs verification of cell status information before power delivery is enabled. The master processor verifies status data from multiple battery modules in advance, ensuring all parameters meet mission requirements and compatibility criteria before allowing operation, thus preventing unsafe conditions while maintaining efficiency.
Solution Approach 2:
The system continuously monitors cell status parameters (temperature, voltage, current) and provides feedback to the master processor. This real-time feedback mechanism allows for ongoing verification without requiring complete system shutdowns, maintaining reliability while minimizing time losses through continuous rather than periodic checking.
3Reliability
If the master processor receives and verifies status information from multiple battery modules, then power delivery safety improves, but the processing load and system complexity increase
Solution Approach 1:
The verification workload is segmented and distributed: individual battery module processors perform initial status monitoring and preliminary verification of their respective cells, then submit summarized status information to the master processor. This distribution reduces the processing load on the master processor while maintaining comprehensive verification for safety.
Solution Approach 2:
The system performs verification of essential safety parameters (temperature, voltage, current status) with appropriate thoroughness, rather than attempting to monitor every possible cell characteristic. This partial verification approach ensures safety for critical parameters while avoiding excessive processing complexity.
