Battery SOH Correction for Accurate CO2 Emission Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems fail to accurately calculate the environmental impact, particularly greenhouse gas emissions, due to discrepancies between calculated and actual emissions, necessitating a more precise method to determine the environmental load factors associated with battery usage.
Innovation Solution
A battery management system and program that calculates State of Health (SOH) of rechargeable batteries, corrects this information using performance data, and computes greenhouse gas emissions like CO2 based on SOH, employing a battery management unit, server, and display device to provide accurate emission data.

Engineering Contradiction Analysis
1Measurement precision
If conventional processing apparatus is used to calculate environmental factors, then calculation process is simple, but calculation accuracy of emission amounts is insufficient
Solution Approach 1:
The patent segments the battery management system into distinct functional modules: a battery information acquisition unit that collects raw data, an SOH calculation unit that processes degradation metrics, and an emission calculation unit that computes environmental impact. This segmentation allows each module to specialize in specific tasks, improving overall calculation accuracy while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The system implements feedback mechanisms where calculated SOH values and emission amounts are continuously updated based on new battery monitoring data. The emission calculation unit receives feedback from the SOH calculation unit, and both are periodically validated against actual battery performance data, creating a closed-loop system that progressively improves accuracy without requiring complete system redesign.
2Measurement precision
If SOH is calculated based on battery monitoring data, then real-time tracking is enabled, but accuracy of SOH information is insufficient due to lack of correction
Solution Approach 1:
The system performs preliminary SOH calculation based on available battery monitoring data before actual battery testing or performance measurement is available. This preliminary SOH value serves as an initial estimate that can be quickly updated later when correction data becomes available, allowing real-time tracking to continue without interruption while progressively improving accuracy.
Solution Approach 2:
The patent applies partial correction by updating SOH values only when correction data becomes available, rather than continuously recalculating from scratch. This partial action approach maintains real-time functionality while improving accuracy at appropriate intervals, balancing the trade-off between calculation time and information accuracy.
