Battery Value Index Using SOC Window Crossover for Residual Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to appropriately evaluate the value of rechargeable batteries in various situations before, during, and after leasing, especially since existing systems cannot treat SLI batteries as subjects for operating leases due to their shorter lifespan compared to electric vehicles.
Innovation Solution
A battery value evaluation support apparatus and method that assesses the value of rechargeable batteries by collecting and processing data on battery design, history, and usage conditions, allowing for the calculation of residual value and lease fees based on the battery's remaining life and market value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If operating lease is applied to rechargeable batteries, then lease fee can be reduced by residual value, but battery value evaluation system must be established to determine residual value
Solution Approach 1:
The battery value evaluation system is segmented into multiple independent components: data collection unit (collecting battery information), data processing unit (analyzing usage patterns), and value calculation unit (computing residual value). This segmentation allows each component to perform its specific function efficiently while reducing the overall complexity of the evaluation system.
Solution Approach 2:
The patent introduces an intermediary battery value evaluation system that acts as a mediator between the battery lessor and lessee. This intermediary system objectively determines residual value based on collected battery data, eliminating the need for complex negotiations and disputes between parties while simplifying the leasing process.
2Loss of energy
If residual value is set for battery lease, then lease fee is reduced, but difficulty in evaluating battery value increases
Solution Approach 1:
The battery value evaluation system implements feedback mechanisms by continuously collecting battery performance data during usage and using this information to adjust and refine residual value calculations. This feedback loop enables accurate value assessment despite the complexity of measuring battery degradation and remaining capacity.
Solution Approach 2:
The patent replaces complex manual battery value assessment methods with automated electronic data processing. The system uses computer algorithms to analyze battery data, calculate degradation patterns, and determine residual value, thereby reducing the difficulty of measuring battery value while maintaining accuracy.
3Ease of operation
If SLI battery is treated as consumable, then simplicity is maintained, but operating lease opportunity is lost
Solution Approach 1:
The patent changes the classification parameter of batteries from 'consumable' to 'leaseable asset' by establishing objective criteria for value evaluation. This parameter change enables the application of operating lease models to batteries while maintaining operational simplicity through automated evaluation systems that objectively determine battery value and residual life.

AI summary
According to one embodiment, a method for making a battery value evaluation index, includes applying a predetermined charge/discharge pattern to a predetermined battery, detecting a largest SOC value and a smallest SOC value of the predetermined battery, and setting a width between the largest SOC value and the smallest SOC value as "A", detecting a charge limit SOC value at which the predetermined battery shows the highest SOC value, detecting a discharge limit SOC value at which the predetermined battery shows the lowest SOC value, and setting a width between the charge limit SOC value and the discharge limit SOC value as "B", and determining that a life of the predetermined battery has ended in the predetermined charge/discharge pattern when a state of B>A has changed into a state of B≤A.
