  • Patent number: 9851393
    Abstract: A fuse system includes a fuse element configured to receive a current. A controller is operatively connected to the fuse element and has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for determining a remaining fuse life (LR) of the fuse element. Execution of the instructions by the processor causes the controller to determine a temperature (T) of the fuse element. The fuse system may be part of a vehicle. The controller may be configured to determine if the remaining fuse life is below first and second thresholds. If the remaining fuse life is above the second threshold, a first message may be displayed to a vehicle display. If the remaining fuse life is below the second threshold, the vehicle may be shifted to a predefined alternative operating mode.

  • Patent number: 9417270
    Abstract: Disclosed herein are various systems and methods for capturing and utilizing temperature information in a battery pack. An electrical measurement system may be configured to determine a subdivision electrical parameter associated with one or more subdivisions, and a thermal measurement system configured to determine and track a thermal parameter associated with one or more subdivisions. A battery model may utilize the thermal parameter and the electrical parameter to estimate a characteristic of one or more battery subdivisions. In some embodiments, the battery model may further estimate a second thermal parameter of a second subdivision based upon a location of the second subdivision within the battery pack and based on the estimated characteristic of a first subdivision. Some embodiments may further estimate a life assessment of one or more subdivisions based at least in part on the subdivision electrical parameter and the thermal parameter.
