Electrode Virtual Identification for Battery Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traceability of positive electrodes in electric vehicle battery cells is compromised due to the difficulty in assigning physical identifiers, as the foils are made of aluminum and are prone to fire, soot, or dust during marking processes.
Innovation Solution
A monitoring system that assigns virtual identifiers to positive electrodes based on specification information and position coordinates, using a programmable logic controller, inspection device, and controller to manage and integrate identification and inspection information, ensuring traceability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical identifiers are marked on positive electrode foils, then traceability of negative electrodes is ensured, but fire, soot, or dust occurs during marking making identification impossible
Solution Approach 1:
The patent uses optical copying to capture images of positive electrode foils, creating digital replicas that can be stored and analyzed without physically marking the foils. This copying approach allows traceability through image recognition and analysis while avoiding the harmful effects of physical marking processes.
Solution Approach 2:
The patent replaces mechanical marking systems with optical detection and image processing systems. Instead of using physical markers that cause fire and soot, the system uses cameras and image recognition algorithms to identify and track positive electrode foils, eliminating the harmful marking process while maintaining traceability.
2Ease of manufacture
If physical marking is performed on positive electrodes, then identification is possible, but the aluminum foil material causes fire and soot generation
Solution Approach 1:
The system creates digital copies of positive electrode foils through optical imaging. These image copies are stored and processed to enable identification and tracking without requiring physical marking. The copying method eliminates fire and soot generation while maintaining ease of identification through digital image analysis.
Solution Approach 2:
The patent introduces optical images as an intermediary between the positive electrode foil and the identification system. Instead of directly marking the foil, the system captures and processes images of the foil, using these images as mediators for identification. This intermediary approach avoids direct contact and harmful marking while enabling easy identification.
3Reliability
If virtual identifiers are assigned based on specification information and coordinates, then traceability is secured without physical marking, but system complexity increases
Solution Approach 1:
The system assigns virtual identifiers by creating and storing optical copies of positive electrode foils with associated metadata (specification information and coordinates). This copying approach enables traceability through digital image matching rather than physical marking, securing reliability while the complexity is managed through automated image processing and database management.
Solution Approach 2:
The patent replaces simple physical marking systems with automated optical detection and image processing systems. While this increases device complexity, it eliminates the harmful effects of physical marking and provides more reliable traceability. The complexity is offset by the benefits of non-contact identification and the ability to capture multiple characteristics through imaging.
