Abstract: A method for controlling a battery charger circuit of a vehicle. The method includes injecting a first current pulse between at least one line and a protective earth connection of the battery charger circuit. The method also includes measuring at least one line voltage value of at least one node of the battery charger circuit. The method also includes identifying a noise value by performing one or more operations on the battery charger circuit. The method also includes determining a protective earth connection impedance based on the at least one line voltage value and the noise value.

Abstract: An electrically powered vehicle system includes a DC/DC converter stage with a rectified input terminal which receives a rectified input from an AC power input. The system also includes a vehicle battery which receives power output from the DC/DC converter stage, via a first link between the rectified input terminal and the DC/DC converter stage. A second link is connected to the first link and to a vehicle device.

Abstract: A method for detecting a fault in a battery charger circuit of a vehicle includes determining, based on at least one expected voltage value of an incoming alternating current source, a first threshold. The method also includes measuring at least one line voltage value associated with the incoming alternating current source that provides power to the battery charger circuit. The method also includes determining whether the measured at least one line voltage value is greater than the first threshold.

Abstract: Various features for allowing a user to control a camera in an intuitive manner are described. Various features allow a user to control one or more camera settings via a touch screen. In some embodiments a rotating wheel is simulated on the display screen to show user selectable camera setting values with the values being displayed as if on the surface of the wheel with a currently selected value being closest to the user, e.g., in the center, and values above and below the currently selected value being shown using a smaller size as if further away from the user. A current setting for the feature being controlled is displayed near the center of the screen in some embodiments. A currently selected value is sometimes shown larger than other user selectable settings. The camera settings include an ISO setting, a focal length, e.g., zoom setting, and/or an exposure control setting.

Abstract: A system and method is provided for detecting vehicle proximity in an electric vehicle supply equipment (EVSE). A sensor may be configured to detect a presence of a vehicle within a predetermined distance of the EVSE. A processor may be configured to determine that the vehicle is in proximity of the EVSE in response to the sensor detecting the presence of the vehicle. The processor may be further configured to generate an alert in response to a determination that the vehicle is in proximity of the EVSE.
