Battery CO2 Burden Allocation Using SOH at Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for managing carbon dioxide (CO2) emissions from secondary battery manufacturing do not fairly apportion the burden between automobile manufacturers and recycling business operators, leading to unfairness in CO2 emission responsibilities.
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 State of Health (SOH) metric to determine the appropriate burden share between the manufacturer and the recycling business operator.
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 can be held responsible for environmental impact, but the recycling business operator cannot be fairly burdened with CO2 emissions despite utilizing the batteries
Solution Approach 1:
The patent changes the parameter of CO2 emission burden allocation from a fixed manufacturer-only responsibility to a dynamic allocation based on battery deterioration degree. The controller calculates the state of health (SOH) and uses it to determine the apportionment ratio, transforming the emission burden from a static parameter to one that varies according to battery condition.
Solution Approach 2:
The system implements feedback by continuously monitoring battery deterioration through SOH calculations and using this information to adjust the CO2 emission burden allocation. The controller receives battery status information, calculates deterioration degree, and accordingly determines the fair apportionment between manufacturer and recycler, creating a closed-loop system that responds to actual battery conditions.
2Ease of operation
If the recycling business operator operates without bearing any CO2 emissions burden, then the operator can freely utilize recycled batteries, but unfairness arises between the manufacturer and the recycler
Solution Approach 1:
The patent transforms the CO2 emission burden parameter from zero for recyclers to a dynamic value based on battery deterioration. The controller calculates the recycler's burden as a proportion of total emissions corresponding to the battery's deterioration degree, allowing recyclers to operate with a fair but not excessive burden that reflects actual battery wear.
3Device complexity
If CO2 emissions are apportioned without considering battery deterioration degree, then the allocation process is simple, but the apportionment becomes unfair between manufacturer and recycler
Solution Approach 1:
The system uses feedback from battery monitoring systems to automatically determine deterioration degree and adjust apportionment ratios. The controller receives real-time or periodic battery status data, calculates SOH, and uses this feedback to dynamically adjust the CO2 emission allocation, ensuring fairness without requiring complex manual assessment procedures.
Solution Approach 2:
The battery management system performs self-assessment of its own deterioration through embedded sensors and controllers that monitor voltage, current, temperature, and charge cycles. This self-service capability eliminates the need for external complex evaluation systems, maintaining relative simplicity while achieving accurate and fair CO2 apportionment based on actual battery condition.

AI summary
A management device includes a storage configured to store an amount of CO2 emissions emitted by manufacturing a secondary battery, and a controller 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.
