Abstract: A charging system includes a service office, a charging station, a charging plug, a plurality of cameras, and a controller. The charging station is in communication with the service office. The service office is remote from the charging station. The charging plug is coupled to the charging station. The charging plug is operable to charge a battery of an electric vehicle. The plurality of cameras is coupled to the charging station. The plurality of cameras is operable to generate a plurality of images of the charging plug from a plurality of directions. The controller is disposed in the charging station. The controller is operable to transmit the plurality of images to the service office. The service office is operable to determine a physical state of the charging plug based on the plurality of images received from the controller.

Abstract: An electrified powertrain system including a battery pack, electric motor, and a local controller. In response to a connection of the battery pack to an offboard charging station having a station controller, the local controller receives a reported charging limit from and transmits an initial charge request signal to the station controller. The initial charge request signal is a request for charging power or current at the reported charging limit. The vehicle controller also detects a threshold oscillation of the charging limit during an active charging event during which the battery pack recharges. In response to the threshold oscillation during the active charging event, the vehicle controller temporarily reduces the initial charge request to a derated level.
