HIGH VOLTAGE BATTERY SYSTEM CONTACTOR CONTROL

An electrified vehicle includes an electrified powertrain, a high voltage (HV) battery system, and one or more contactors configured to selectively connect the HV battery system to a HV bus, the one or more contactors producing a contactor noise when opened. An entertainment module is configured to generate audio sound. A controller is programmed to detect an ignition of the vehicle is keyed OFF, initiate a contactor opening sequence with a change of mind timer configured to provide a predetermined time period for a driver to change their mind about keying OFF the vehicle before the one or more contactors are commanded open, determine if the generated audio sound is louder than the contactor noise, and command the one or more contactors to open if the generated audio sound is louder than the contactor noise and the change of mind timer has expired, to thereby mask the contactor noise.
