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.
