A charging system for a high voltage battery includes a pair of contactors each electrically connected to one of positive and negative terminals of the battery and configured to enable charging of the battery when closed; and a controller programmed to generate a notification indicating that one of the contactors is welded closed based on port voltage values achieved while issuing a predetermined sequence of open and close commands to the contactors after charge completion.
