System and method for reusing an electric vehicle battery

This invention describes a way to reuse old electric vehicle battery packs without having to open them up. It uses a special controller that plugs into the battery's existing computer system, pretending to be a car or other vehicle. This controller then manages the battery's charging, discharging, and temperature to ensure it operates safely and optimally in a new application. The claims specifically describe a method where a central controller receives and processes signals from a control unit connected to the battery to determine its status.

Why it matters: The accelerating retirement of electric vehicles since 2022, reflected in the battery reuse classifications, means a significantly larger and more diverse pool of end-of-life battery packs now exists, increasing the economic incentive for this unopened reuse method.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
