Assembled Battery Reuse System with Cell Count Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost associated with rebuilding assembled batteries is due to the process of disassembling and inspecting single cells, which is inefficient and increases costs.
Innovation Solution
An assembled battery reusing system that includes an information acquisition unit, a rebuild candidate determining unit, a single cell amount determining unit, and a determination unit to assess whether retrieved batteries are suitable for rebuilding, optimizing the selection and processing of batteries for rebuilding based on the amount of usable single cells and required cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retrieved assembled batteries are disassembled into single cells for rebuilding, then the batteries can be reused, but the cost increases due to the disassembly and inspection processes
Solution Approach 1:
The system performs preliminary assessment of retrieved assembled batteries by acquiring information about their state and determining rebuild candidacy before actual disassembly. The single cell amount determining unit calculates how many usable single cells exist in advance, allowing the determination unit to decide whether rebuilding is worthwhile before incurring disassembly costs.
Solution Approach 2:
The system uses information copying and data processing to assess battery viability. Instead of physically disassembling every battery to check cell usability, the system acquires information about the assembled battery state and determines rebuild candidacy through computational analysis, replacing physical inspection with information-based assessment.
2Quantity of substance
If all retrieved assembled batteries are sent to the rebuilding process, then enough single cells are available for manufacturing, but unnecessary processing increases costs
Solution Approach 1:
The system applies partial action by determining only the necessary number of assembled batteries to send for rebuilding. The single cell amount determining unit calculates the exact number of usable single cells available, and the determination unit sends only enough assembled batteries to meet manufacturing requirements, avoiding excessive processing of batteries that would not contribute to the target quantity.
Solution Approach 2:
The system uses feedback loops where the single cell amount determining unit continuously assesses the number of usable single cells in retrieved batteries, compares this against manufacturing requirements, and adjusts the determination of which batteries to send for rebuilding. This feedback mechanism ensures optimal resource allocation without over-processing.
3Manufacturing precision
If detailed inspection of single cells is performed during rebuilding, then the quality of rebuilt batteries is ensured, but the time and cost increase
Solution Approach 1:
The system performs preliminary determination of rebuild candidacy and single cell usability before the actual rebuilding process. By assessing battery state and calculating usable cell counts in advance, the system pre-filters batteries that warrant detailed inspection, reducing the overall inspection burden while maintaining quality standards for selected candidates.

AI summary
An assembled battery reusing system for reusing an assembled battery including a plurality of single cells is provided. The rebuild candidate determining unit (430) determines based on the information about the assembled battery whether a retrieved assembled battery is a rebuild candidate, and the information is acquired by the assembled battery information acquisition unit (i.e. communication unit) (420). The single cell amount determining unit (440) determines an amount of rebuilding-usable single cells included in the rebuild-candidate assembled battery determined by the rebuild candidate determining unit (430). The assembled battery demand information acquisition unit (460) acquires an amount of rebuilding-required single cells required to rebuild a required new assembled battery. The determination unit (470) determines based on the determined amount of rebuilding-usable single cells and the acquired amount of rebuilding-required single cells whether to send the rebuild-candidate assembled battery to a rebuilding process.
