Vehicle Battery Fault Response Using Weighted Context Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical energy storage systems in vehicles manage faults independently without considering broader vehicle context, leading to suboptimal safety outcomes due to the influence of vehicle surroundings and operating conditions.
Innovation Solution
A computer system that integrates fault detection with vehicle data, including location and surroundings, to determine a safe fault reaction based on weighted inputs, considering the impact on vehicle and passenger safety, and decides on maintaining or disconnecting energy storage packs accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fault management is performed independently at the battery pack level, then the response speed to faults is improved, but the safety outcome deteriorates due to lack of vehicle context consideration
Solution Approach 1:
The patent merges the local fault detection capability at the battery pack level with global vehicle context information (location, surroundings, operating conditions) by integrating data from multiple sources including GPS, sensors, and vehicle systems into a unified fault management approach that considers both local and global factors simultaneously
Solution Approach 2:
The fault management system is designed to perform multiple functions: it detects local battery faults, evaluates global vehicle context, determines appropriate responses, and coordinates with other vehicle systems, making it a multi-functional system that addresses both rapid response and comprehensive safety considerations
2Reliability
If the system considers broader vehicle context and surroundings data, then the safety outcome is improved, but the system complexity increases
Solution Approach 1:
The system segments the fault management process into distinct functional modules: fault detection module, context data collection module, risk assessment module, and response determination module. Each module handles specific tasks, making the overall complex system manageable through functional decomposition
Solution Approach 2:
The patent introduces an intermediary processing layer that collects, integrates, and evaluates data from multiple vehicle systems and external sources. This intermediary layer acts as a mediator between raw data from various sensors and the final fault response decisions, simplifying the overall system architecture by centralizing data processing
