  "patent_number": "US 20250246702",
  "country": "US",
  "title": "Mobile Factories for Recycling Used Electric Vehicle Batteries",
  "original_title": "Movable battery pack processing device and processing method",
  "summary": "This patent describes a system of movable containers that can be brought to a location to safely discharge, cool, disassemble, and crush used battery packs, making the recycling process more flexible and efficient.",
  "what_it_does": "This invention provides a portable system for processing used battery packs, like those from electric vehicles. It uses several specialized containers that can be moved to where the batteries are located. A first container handles initial steps, either discharging the battery's power or cooling it (Claim 1). This container might use a 'reverse voltage discharge device' to safely remove energy (Claim 5). Next, a second container receives the processed battery pack and disassembles it (Claim 1). This disassembly can involve tools like a blade, laser, or waterjet cutting device (Claim 6). Finally, a third container crushes the disassembled battery pack, often using a shredding device (Claim 1, Claim 7). For example, a company could move these containers to a car dealership or repair shop to process old EV batteries on-site, rather than shipping them to a fixed recycling plant.",
  "what_it_does_not_cover": [
    "Does not cover a stationary, fixed-location battery recycling plant where containers are not designed to be moved to the battery's location (Claim 2, Claim 13).",
    "Does not cover a system where the discharge, disassembly, and crushing steps all occur within a single, non-modular unit (Claim 1).",
    "Does not cover a processing device that only performs one or two of the steps (discharge/cool, disassemble, crush) without the full sequence of modules (Claim 1).",
    "Does not cover systems that do not use separate, interconnected containers for each primary processing stage (Claim 1, Claim 4).",
    "Does not cover the specific chemical processes for extracting materials after crushing, only the mechanical processing up to and including crushing and sorting pole pieces (Claim 9, Claim 10)."

  "abstract": "The present invention relates to a movable battery pack processing device comprising: a first container to which a discharging module or a cooling module is mounted; and a second container to which a battery pack processed by the discharging module or the cooling module of the first container is transferred and to which a disassembling module for disassembling the battery pack is mounted. According to the present invention, a waste battery disassembling process is modularized, so that cost required for a waste battery processing can be reduced and stability also can be significantly improved.",
