BEV Battery Residual Value Modeling for Reuse-Linked Finance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The spread of battery electric vehicles is hindered by low energy density batteries, leading to premature disposal and environmental pollution, with residual capacity batteries having potential economic value if reused effectively.
Innovation Solution
A financial product generation matrix is created using artificial intelligence to determine the value of battery electric vehicle batteries, managing risk and enabling the reuse of batteries through a system that includes a battery value evaluation device, financial product generation device, risk management, fraudulent use determination, and disabling mechanisms.

Engineering Contradiction Analysis
1Use of energy by moving object
If the chargeable capacity of batteries is increased to improve mileage, then the energy density must be increased, but when batteries reach critical capacity (80%), they are considered waste and must be disposed of
Solution Approach 1:
The patent applies parameter changes by transitioning batteries from one functional state to another based on capacity degradation. When batteries reach 80% capacity, they are not disposed of but rather repurposed for stationary energy storage applications where lower performance requirements allow continued utilization. This parameter-based reclassification enables extended battery lifecycle and reduces waste.
Solution Approach 2:
The patent converts the harmful effect of battery capacity degradation into a beneficial outcome by creating a secondary market for used batteries in stationary energy storage. What would traditionally be waste (degraded batteries) becomes a valuable resource for grid stabilization, renewable energy integration, and peak demand management, thereby eliminating disposal issues and environmental pollution.
2Reliability
If batteries are disposed of when reaching critical capacity, then safety and performance requirements are maintained, but environmental pollution occurs and resources are wasted
Solution Approach 1:
The patent implements discarding and recovering by systematically removing batteries from vehicle service when they reach critical capacity and recovering their residual value for stationary energy storage applications. This process prevents complete disposal and environmental pollution while maintaining safety standards through controlled transition and monitoring of repurposed batteries.
Solution Approach 2:
The patent applies universality by enabling batteries to serve multiple functions across different application domains. Batteries transition from primary function (vehicle propulsion) to secondary function (stationary energy storage), allowing the same physical asset to provide value in multiple contexts and extending overall service life while reducing environmental impact.
3Measurement precision
If diagnostic tests are performed to determine battery value for reuse, then accurate valuation is achieved, but additional time and cost are required
Solution Approach 1:
The patent applies preliminary action by performing battery diagnostics and valuation assessments proactively when batteries reach critical capacity in vehicles, before they are transferred to stationary storage applications. This advance evaluation ensures accurate pricing and matching of batteries to appropriate secondary uses, reducing delays and enabling smooth transitions without compromising measurement precision.

AI summary
A method of providing financial service based on BEV (battery electric vehicle) and a financial service system for performing the method can include generating, by a battery electric vehicle financial product generation device, a battery electric vehicle-based financial product and adjusting, by a residual value-based risk management device, a risk of the financial product based on battery value evaluation data.
