Abstract
Methods and systems are provided for monitoring high voltage (HV) exposure hours of a HV system in an electric vehicle (EV). Projected HV exposure hours is generated at one of a future vehicle age and a future EV mileage and is based on current HV exposure hours and historical HV exposure hours. The current HV exposure hours and the historical HV exposure hours are based on use of the battery system to supply power to vehicle propulsion loads and the at least one of offboard vehicle loads and onboard accessory loads. When the projected HV exposure hours is greater than a HV exposure hour threshold, a HV exposure hour alert associated with limitations in connection with the use of the battery system to supply power to the at least one of the offboard vehicle loads and the onboard accessory loads is generated for display on a display device.
