Secondary Battery Module Information Storage for Reuse Grading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current recycling techniques for large-sized secondary batteries, such as nickel-metal hydride and lithium-ion batteries, are inadequate, leading to significant disposal issues and resource wastage, as they cannot effectively reuse batteries due to loss of electrical characteristic and usage history information during disassembly.
Innovation Solution
A secondary battery module with integrated battery information storage means and interface connections to a battery controller, allowing for the storage and retrieval of electrical characteristic and usage history information, enabling efficient grading and reuse of modules through a battery information management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If secondary battery modules are disassembled for recycling, then battery materials can be recovered, but electrical characteristic and usage history information is lost
Solution Approach 1:
The patent divides the battery system into modular units (battery modules) that can be independently disassembled and recycled. Each module retains its information storage capability, allowing selective disassembly of battery components while preserving critical information for reuse decisions.
Solution Approach 2:
The patent creates a digital copy of battery information (electrical characteristics and usage history) stored in non-transitory memory within each battery module. This digital twin allows the original physical battery to be disassembled for material recovery while the information copy enables informed decisions about battery reuse or recycling.
2Adaptability or versatility
If battery information is stored externally in controllers, then module independence is improved, but information loss during disassembly occurs
Solution Approach 1:
The patent merges the information storage function directly into the battery module itself by integrating non-transitory memory and control circuits within the module housing. This combination ensures that both the battery module and its information are transferred together during disassembly, maintaining module independence while preventing information loss.
3Power
If large-sized secondary batteries are used for high output, then power requirements are met, but disposal quantity increases rapidly
Solution Approach 1:
The patent implements a feedback mechanism where battery information (usage history, electrical characteristics, health status) is continuously monitored and stored. This feedback enables informed decisions about battery reuse potential, allowing batteries to be recharged and reused when possible, thereby reducing disposal quantity while maintaining required power output.
Solution Approach 2:
The patent establishes a systematic approach where batteries are first evaluated for reuse based on stored information, then selectively discarded or recovered. Batteries meeting performance thresholds are recovered and reused, while only those failing to meet standards are disposed of, minimizing waste while satisfying power requirements.

AI summary
A secondary battery module includes a battery information storage unit for storing electric characteristic information and usage history information of the secondary battery module. A battery information management device and a terminal device respectively include interfaces to be connected to the secondary battery module. The battery information management device is provided with a battery information database. The battery information management device is connected to the terminal device through a communications network. In this way, battery information stored in the battery information storage unit, which is acquired by the battery information management device and the terminal device, is accumulated in the battery information database. Moreover, the battery information management device grades the secondary battery module for reuse based on the battery information and a predetermined threshold.
