  • Lithium plating detection and mitigation in electric vehicle batteries
    Patent number: 11603011
    Abstract: A vehicle includes a traction battery and a controller. The controller is programmed to, in response to dynamic resistance and capacity of the traction battery for a drive cycle differing from dynamic resistance and capacity of the traction battery for a previous drive cycle by threshold percentages, controlling the traction battery to reduce lithium plating.
    Type: Grant
    Filed: November 22, 2019
    Date of Patent: March 14, 2023
    Assignee: Ford Global Technologies, LLC
    Inventors: Satish B. Chikkannanavar, Jonathan Tao, Matthew Allen Tomai, Christian Edward Shaffer, Kevin Vander Laan
  • METHOD AND APPARATUS FOR SELECTIVE DRIVE-MODE ENABLEMENT
    Publication number: 20220004189
    Abstract: A system includes a processor configured to determine a driver identity.
    Type: Application

  • Method and apparatus for selective drive-mode enablement
    Patent number: 11137757
    Abstract: A system includes a processor configured to determine a driver identity. The processor is also configured to receive a request for a change to a driving mode and responsive to the request, enable or deny the driving mode based on mode-correlation to one of a predefined set of permissible driving modes pre-associated with the driver identity.

  • Lithium replenishment cell to enhance beginning of life capacity
    Patent number: 10483598
    Abstract: A method for fabricating an electrode sandwich includes, responsive to an amount of cyclable lithium lost being greater than a predefined threshold, initiating, by a controller, current flow between the sandwich and a lithium replenishment electrode in ionic conductivity with the sandwich via replenishment gaps to transfer lithium thereto, and, responsive to an amount of transferred lithium corresponding to the amount lost, hot-press sealing the replenishment gaps and detaching the replenishment electrode from the sandwich.

  • METHOD AND APPARATUS FOR ENVIRONMENT-SENSITIVE SELECTIVE DRIVE-MODE ENABLEMENT
    Publication number: 20190291745
    Abstract: A system includes a processor configured to determine a driver identity. The processor is also configured to access a profile corresponding to the identity, including driving mode permissibility parameters defining permissible driving modes for an identified driver, correlated to defined environmental conditions. The processor is further configured to engage a requested driving mode responsive to the driving mode being permitted by the parameters under a defined environmental condition that corresponds to a detected environmental condition.

  • Vehicle multi-passenger phone mode
    Patent number: 10291996
    Abstract: A vehicle includes one or more microphones that are each configured to selectively provide sound signals from one or more seating positions in the vehicle. A controller is programmed to receive an input indicative of a request to enter a group conversation mode upon initiation of a call, and, responsive to receiving the input, enable the microphones to selectively provide sound signals from all of the seating positions.
