Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft battery systems face challenges due to limited capacity monitoring, leading to unexpected power failures and inefficient replacement schedules based on incorrect specifications, resulting in economic losses and logistical issues.
Innovation Solution
Implementing a health monitoring unit within the battery system to collect and analyze data on battery voltage, current, and temperature, storing this information for performance evaluation and comparison against health thresholds to determine the actual state of battery life and health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery replacement is based on fixed scheduled maintenance periods, then replacement timing is predetermined and simple to manage, but replacements may occur unnecessarily early or late leading to economic losses and operational disruptions
Solution Approach 1:
The system continuously monitors battery health parameters (voltage, current, temperature, cycle count) and uses this feedback to dynamically adjust replacement timing. The health monitoring unit provides real-time data that feeds into the replacement scheduling system, enabling decisions based on actual battery condition rather than fixed schedules.
Solution Approach 2:
The replacement schedule transitions from a static fixed-time model to a dynamic condition-based model. The system adapts the replacement timing based on varying operational conditions, battery usage patterns, and environmental factors, optimizing both productivity and reliability.
2Reliability
If battery health monitoring is not implemented, then the system is simpler and cheaper, but battery failures go undetected leading to unexpected power loss and operational disruptions
Solution Approach 1:
The battery system performs self-diagnosis through integrated health monitoring that automatically tracks its own parameters. The system monitors its voltage, current, temperature, and cycle count without requiring external intervention, enabling autonomous health assessment and early warning of potential failures.
Solution Approach 2:
The monitoring system detects battery degradation trends before critical failure occurs. By tracking health parameters over time and comparing against thresholds, the system performs preliminary assessment that allows proactive maintenance scheduling, preventing unexpected power loss and operational disruptions.
3Adaptability or versatility
If battery specifications are used for replacement scheduling, then replacement timing is easily determined from manufacturer data, but specifications may be incorrect due to varying usage conditions, climate, and frequency of use
Solution Approach 1:
The system transitions from using fixed manufacturer specifications to measuring actual battery performance parameters under real operating conditions. By monitoring voltage, current, temperature, and cycle count specific to each application, the system determines accurate battery life that adapts to varying usage conditions, climate, and frequency of use.
Solution Approach 2:
The monitoring system tailors battery life assessment to local operating conditions at each specific application site. Rather than applying universal manufacturer specifications, the system captures location-specific parameters including climate, usage patterns, and environmental factors that affect battery performance.
Data Source
AI summary
A method, system, and apparatus are provided for managing battery data. A health monitoring unit monitors a number of battery units for battery data. A data logger stores the battery data. A data processing system identifies performance information from the battery data. A new battery design may be modified based on the performance data. Also, the performance data may be compared to health thresholds for inconsistencies to identify when the number of battery units may need to be serviced.
