Battery Component Identification via RFID for Safe Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems lack efficient methods for identifying and replacing faulty components, leading to potential safety risks and reduced functionality, especially in critical applications like hybrid vehicles and renewable energy systems.
Innovation Solution
The battery system incorporates an interface for a maintenance module that uses identification features, such as RFID transponders or graphical codes, to uniquely identify components, allowing for easy replacement of faulty parts while ensuring compatibility and safety through data association and monitoring of operating parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If battery components are made interchangeable without identification features, then ease of repair is improved, but reliability deteriorates due to inability to ensure compatibility and track component history
Solution Approach 1:
The patent uses identification features (such as graphical codes or RFID transponders) that serve as information copies of the component's unique identity and technical data. These identification features enable the maintenance module to retrieve and verify component information without physically examining the component itself, thus ensuring compatibility and reliability while maintaining ease of replacement.
Solution Approach 2:
The maintenance module acts as an intermediary between the interchangeable components and the battery system. It reads the identification features on components, retrieves associated technical data from memory, and ensures proper matching and integration. This intermediary function guarantees component compatibility and tracks component history, resolving the contradiction between ease of repair and reliability.
2Reliability
If all battery components are monitored individually with sensors, then reliability is improved through early fault detection, but device complexity increases
Solution Approach 1:
The control means and maintenance module are designed with multi-functional capabilities. The control means not only manages battery operations but also stores identification features and technical data of components. The maintenance module performs multiple functions including reading identification features, retrieving technical data, comparing components, and controlling the interchange process. This universality reduces the need for separate dedicated monitoring systems, thereby reducing complexity while maintaining reliability.
3Reliability
If technical data are stored in nonvolatile memory within control means, then reliability is improved through data availability, but device complexity increases due to additional memory units
Solution Approach 1:
The patent merges the storage function for identification features and technical data into the existing control means of the battery system. Rather than adding separate dedicated storage devices, the control means is equipped with nonvolatile memory units that store component information alongside its primary control functions. This integration ensures data availability for component management while minimizing additional complexity through consolidation of functions.
