  • Patent number: 12024046
    Abstract: Charging guidance systems and methods for charging electrified vehicles may be configured to influence a user's charging decisions in a manner that simplifies the vehicle charging experience. Exemplary charging guidance systems may be configured to coach the user to charge a traction battery pack of the vehicle at a lower level charging option as opposed to a higher level charging option. Charging at lower level charging options when certain conditions are met reduces the amount of times the vehicle is charged using more aggressive charging methodologies, thereby improving battery performance, reducing costs, and preserving the life/warranty and asset utilization of the traction battery pack over the entire usage life of electrified vehicles.

  • Patent number: 11738655
    Abstract: A vehicle includes a charging stop switch that accepts a stopping operation for stopping external charging, and an ECU that stops the external charging when the stopping operation is accepted at the charging stop switch. The ECU determines whether or not a specific operation different from the stopping operation at the charging stop switch has been accepted, and when it is determined that the specific operation has been accepted, disables acceptance of the stopping operation. The specific operation is an operation different from an intended operation of a prescribed subject. The vehicle includes an inlet to which a charging connector for external charging can be connected. The ECU detects connection of the charging connector to the inlet, the prescribed subject is the charging connector, and the specific operation is a prescribed number of operations of connecting and disconnecting the prescribed subject within a prescribed time period.

  • Patent number: 11728621
    Abstract: An electronic device includes laser emitters, and a laser driver generating a laser drive signal for the laser emitters based upon a feedback control signal. A steering circuit selectively steers the laser drive signal to a different selected one of the plurality of laser emitters and prevents the laser drive signal from being steered to non-selected ones of the plurality of laser emitters, during each of a plurality of time periods. Control circuitry senses a magnitude of a current of the laser drive signal and generates the feedback control signal based thereupon. The feedback control signal is generated so as to cause the laser driver to generate the laser drive signal as having a current with a substantially constant magnitude.
