Battery Lease Fee Calculation with Environmental Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lease fee of secondary batteries in electrically powered vehicles is excessively increased due to environments that accelerate battery degradation, such as cold temperatures, leading to higher costs for users.
Innovation Solution
A server system that calculates lease fees based on battery degradation information, employing suppression processing and correction coefficients to adjust lease fees according to the vehicle's usage environment, thereby mitigating the impact of environmental factors on battery deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the lease fee is calculated based on the degree of degradation of the secondary battery, then the lease fee reflects the actual battery condition, but the lease fee becomes excessively high when the vehicle is used in environments that accelerate battery deterioration
Solution Approach 1:
The patent introduces a correction coefficient that changes the parameter of lease fee calculation based on environmental factors. When the vehicle operates in environments that accelerate battery degradation (such as extreme temperatures), the correction coefficient adjusts the calculated lease fee to prevent excessive increases, thereby resolving the contradiction between accurate reflection of battery condition and the harmful impact of environmental factors.
2Reliability
If the lease fee is increased to reflect higher degradation rates in harsh environments, then the battery management becomes more accurate, but the financial burden on users increases excessively
Solution Approach 1:
The correction coefficient acts as an intermediary element between the raw degradation data and the final lease fee calculation. It mediates the relationship by introducing environmental context that prevents direct translation of degradation into proportional fee increases, thereby maintaining reliability while reducing excessive financial burden on users.
3Adaptability or versatility
If the lease fee calculation considers all degradation factors including environmental ones, then the calculation is comprehensive, but the lease fee becomes unfair when environmental factors are beyond user control
Solution Approach 1:
The patent applies local quality by differentiating the treatment of degradation factors based on their nature. Environmental factors (which are beyond user control and vary by location) are treated differently from usage factors (which reflect user behavior). The correction coefficient selectively adjusts for environmental conditions while maintaining the integrity of usage-based degradation assessment, thereby achieving comprehensive calculation while ensuring user fairness.

AI summary
A server includes: a communication unit (acquisition unit) that acquires information of a capacity retention (degree of degradation) of a battery (secondary battery); and a processor (control unit) that calculates a lease fee of the battery using the information of the capacity retention. The processor performs suppression processing for suppressing an increase of the lease fee, the increase of the lease fee being based on deterioration (decrease) of the capacity retention due to an environment in which the electrically powered vehicle is used.
