HIGH VOLTAGE BATTERY CONTACTOR WELDING PREVENTION

High voltage battery contactor welding prevention techniques for an electrified vehicle include, in response to a request to perform a high voltage connection procedure, utilizing a supervisory controller to monitor a voltage of the low voltage battery system to determine whether a low voltage battery system of the vehicle has a voltage level sufficient to open/hold the set of contactors during the high voltage connection procedure, when the low voltage battery system has sufficient voltage, commanding by the supervisory controller to a sub-controller to perform the high voltage connection procedure, and when the low voltage battery system does not have sufficient voltage, displaying a low voltage indicator for a user to recharge the low voltage battery system before the high voltage connection procedure can occur.
