Recording Original Battery Model Data in Reused Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively manage secondary batteries that are reassembled from disassembled battery packs or cells, lacking information on the original battery, which hinders product repair and maintenance.
Innovation Solution
A method and system that records data for identifying the model and degradation state of a used secondary battery in the reused battery itself or an attached member, enabling effective management through portable terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery packs, modules, or cells are removed from the used secondary battery to create a reused secondary battery, then the reused secondary battery can be assembled with selected components, but information on the original secondary battery is lost
Solution Approach 1:
The patent applies preliminary action by recording the model information of the original secondary battery into the reused secondary battery during the reassembly process. This ensures that the identification data is captured and preserved before the reused battery enters service, enabling future traceability and management while maintaining the flexibility of selective component reassembly.
2Adaptability or versatility
If the reused secondary battery is assembled from disassembled components, then component selection and reconfiguration are enabled, but product repair and maintenance work cannot be performed according to the original secondary battery specifications
Solution Approach 1:
The patent introduces an intermediary solution by using a portable terminal as a mediator between the reused secondary battery and the management system. The portable terminal reads the recorded model information from the reused battery and transmits it to the server, enabling maintenance personnel to access original battery specifications and perform appropriate repair and maintenance work despite the battery being reassembled from discrete components.
3Reliability
If model information is recorded in the reused secondary battery during production, then identification and management become possible, but additional recording steps and system complexity are introduced
Solution Approach 1:
The patent applies self-service by enabling the reused secondary battery to store its own identification information autonomously. The battery contains the model information of the original battery directly within its structure, allowing it to self-identify when connected to the management system through the portable terminal, thereby reducing the need for external documentation or complex tracking systems.
Solution Approach 2:
The patent uses copying by transferring the model information from the original secondary battery's identification data to the reused secondary battery's storage medium. This creates a digital copy of the essential identification information that enables full traceability and management of the reused battery without requiring the physical original battery to be present.

AI summary
Provided are a reused secondary battery management method and a reused secondary battery management system capable of managing a reused secondary battery even when the reused secondary battery is a secondary battery produced by reusing cells that constitute a used secondary battery. In the secondary battery management method and the secondary battery management system, when the reused secondary battery is a secondary battery produced by reusing cells that constitute the used secondary battery, data for identifying a model of the used secondary battery before being reused is recorded in the reused secondary battery and/or an attached member attached to and used for the reused secondary battery during a period from the production of the reused secondary battery until the start of reuse of the reused secondary battery.
