  "title": "Forecasting When Used Electric Car Batteries Will Be Available for Reuse",
  "original_title": "Recycled secondary battery supply forecast system and recycled secondary battery supply forecast usage",
  "summary": "This patent describes a system that predicts when electric vehicles will reach the end of their useful life and how much capacity their batteries will still have, to forecast the future supply of batteries that can be reused in other applications.",
  "what_it_does": "This system, often a central server, collects two main types of information from many vehicles: performance data about their secondary batteries (like total capacity or maximum output current) and state data about the vehicle itself (like total travel distance or hours used) (Claim 1). It then uses the historical trends of this data to make two key predictions. First, it forecasts when each vehicle will reach its 'end of life,' which is defined by a specific travel distance or amount of time used (Claims 1, 2, 3). Second, it predicts the battery's performance (e.g., remaining capacity) at that vehicle's end of life (Claims 1, 4, 5). Finally, the system combines all these individual vehicle and battery predictions to forecast the total number of recyclable batteries that will become available during a future period, considering their type and expected performance for reuse in separate devices (Claim 1). For example, if a fleet of delivery vans reports their mileage and battery health, the system can predict how many usable batteries will be ready for a second life in energy storage systems next year.",
  "what_it_does_not_cover": [
    "Does not cover forecasting for batteries that are not originally mounted on vehicles (Claim 1).",
    "Does not cover forecasting the end of a vehicle's life without using historical state information, such as past travel distance or used hours (Claim 1).",
    "Does not cover forecasting battery performance without using historical performance information, such as past total capacity or maximum output current (Claim 1).",
    "Does not cover forecasting for batteries that are not intended for reuse in 'separate devices' after their vehicle's end of life (Claim 1).",
    "Does not cover systems where the vehicle's 'end of life' is not determined by a predetermined travel distance or used hours (Claims 1, 2, 3)."

  "abstract": "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.",
