Recycled Battery Supply Forecasting via Vehicle Lifecycle Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies cannot accurately forecast the quantity level and performance level of recyclable secondary batteries that can be supplied, making it difficult for manufacturers to devise effective procurement and manufacturing plans.
Innovation Solution
A system comprising a vehicle life/battery performance forecast unit that analyzes historical data from vehicles to predict the end-of-life performance of secondary batteries and a battery supply quantity forecast unit that predicts the supply quantity of recyclable batteries based on this data, using a battery management server connected via a communication network.

Engineering Contradiction Analysis
1Measurement precision
If conventional battery information management is used to sort batteries by grade, then batteries can be organized for recycling, but the quantity level and performance level of recyclable batteries cannot be forecasted
Solution Approach 1:
The system performs preliminary forecasting of battery end-of-life timing and recyclable battery supply quantity before the actual recycling process. By analyzing battery usage data, degradation trends, and vehicle lifecycle information in advance, the system predicts when batteries will become recyclable and in what quantities, enabling manufacturers to plan procurement and production schedules proactively rather than reactively
Solution Approach 2:
The system establishes a feedback loop where actual battery performance data, usage patterns, and recycling outcomes are continuously collected and fed back into the forecasting model. This allows the system to refine its predictions of recyclable battery quantity, performance levels, and supply timing based on real-world observations, improving forecast accuracy over time
2Ease of manufacture
If secondary batteries are reused in devices after vehicle life, then manufacturing cost is reduced, but it is difficult to plan procurement and manufacturing without knowing supply quantity and timing
Solution Approach 1:
The forecasting system provides advance information about the quantity and timing of recyclable battery supply, allowing device manufacturers to plan their procurement strategies and production schedules in advance. This eliminates the uncertainty and complexity associated with sourcing recycled batteries, enabling smoother integration of battery reuse into manufacturing operations
Solution Approach 2:
The system acts as an intermediary information platform between vehicle operators (who have used batteries) and device manufacturers (who need recycled batteries). By providing standardized forecast data about battery supply quantity, performance, and timing, the system facilitates efficient matching of supply and demand, reducing transaction costs and planning complexity
3Ease of manufacture
If recycled materials are used for new battery manufacturing, then manufacturing cost is reduced, but supply quantity and timing of recycled materials must be known in advance
Solution Approach 1:
The system forecasts the quantity and timing of recyclable batteries before they are actually collected and processed into recycled materials. This advance prediction allows battery manufacturers to plan their material procurement and production schedules optimally, ensuring that recycled materials are available when needed without excessive inventory holding periods

AI summary
A recycled battery supply forecast unit 201 of a battery management server 20 receives, from a plurality of vehicles 40, performance information of a secondary battery 403 mounted on each of the vehicles 40 and state information of the vehicle for determining a life of the vehicle 40, makes a forecast of an end of life of the vehicle 40 by using history of the state information of that vehicle, and makes a forecast of performance of the secondary battery 403 at the end of life of that vehicle 40 by using history of the performance information of the secondary battery 403. In addition, a forecast is made of a supply quantity of recyclable secondary batteries at a certain point in time in the future based on a forecast result of the performance of the secondary battery 203 at the end of life of each vehicle 40.
