Abstract: A vehicle configured to execute one or more methods for detecting function of a charging receptacle during a charging cycle. The methods include supplying a charging current through the pins; monitoring a pin temperature of the pins during the charging current; and applying a first step function to the charging current. The methods may also include monitoring a first step change in the pin temperature during the first step function; comparing the first step change in the pin temperature to a first expected temperature change to create a first deviation; and comparing the first deviation to a predetermined threshold. If the first deviation exceeds the predetermined threshold, signaling a maintenance alert, and if the first deviation is less than the predetermined threshold, logging the first deviation.

Abstract: A non-transitory computer-readable medium and methods capable of being executed thereby are provided. The non-transitory computer-readable medium includes contents that are configured to cause a computing system to perform the method related to a charging port of an electrified vehicle. The method, or methods, include taking a current photo of at least one of a charging receptacle or a cordset of the charging port; image processing the current photo; and determining whether the current photo includes one or more identified faults from the image processed current photo. If one or more identified faults are present in the image processed current photo, at least one of: sending a maintenance message; limiting charging; or adjusting system parameters.
