Battery CO2 Burden Allocation Based on Recycling Deterioration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for managing CO2 emissions from secondary battery manufacturing do not fairly apportion the burden between automobile manufacturers and recycling business operators, leading to unfairness as recycling business operators operate without bearing the emissions costs.
Innovation Solution
A management device and system that calculates and apportions CO2 emissions based on the degree of deterioration of secondary batteries at the time of recycling, using a controller to assess the capacity maintenance rate and update emissions burdens accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automobile manufacturer bears the entire amount of CO2 emissions from secondary battery manufacturing, then the manufacturer maintains full responsibility for emissions, but the recycling business operator operates without bearing any emissions burden, creating unfairness
Solution Approach 1:
The patent segments the CO2 emissions burden between the automobile manufacturer and the recycling business operator based on the degree of deterioration of the secondary battery. The controller calculates the degree of deterioration and apportions the emissions amount accordingly, so that the manufacturer bears emissions for the useful life of the battery while the recycler bears emissions corresponding to the deteriorated portion. This segmentation resolves the unfairness by distributing the emissions burden according to actual responsibility and usage.
2Reliability
If the amount of CO2 emissions is apportioned based on degree of deterioration, then fairness is improved, but the complexity of the management system increases due to needing to track and calculate deterioration
Solution Approach 1:
The patent implements a self-service mechanism where the secondary battery itself provides the necessary information for emissions apportionment. The battery includes a memory that stores its own degree of deterioration information, and a communicator that automatically transmits this information to the management device. This eliminates the need for complex external tracking systems, as the battery autonomously provides the data needed for fair emissions calculation.
Solution Approach 2:
The patent establishes a feedback loop where the degree of deterioration of the secondary battery is continuously monitored and communicated back to the management device. The controller uses this feedback information to dynamically adjust and recalculate the CO2 emissions burden. This feedback mechanism ensures that the emissions apportionment remains accurate and fair throughout the battery's lifecycle, from manufacturing through recycling.

AI summary
A management device (2) includes a storage (27) configured to store an amount of CO2 emissions emitted by manufacturing a secondary battery, and a controller (21; 21A) configured to, when the secondary battery is recycled by a business operator who recycles the secondary battery, apportion the amount of CO2 emissions with the business operator according to a degree of deterioration of the secondary battery at a time of being recycled.
