Abstract
A depletion amount of energy required to charge a user device connected to a device port of a vehicle is estimated based on a state of charge (SoC) of a device battery of the connected user device. Responsive to an expected SoC of a LV battery of the vehicle after providing the depletion amount of energy exceeding a calibrated threshold amount of energy of the LV battery, the connected user device is charged during key off. Otherwise, an engine start/stop schedule defining a time to start an engine of the vehicle and a duration of run time for the engine is utilized to generate additional energy to charge the connected user device to ensure the LV battery remains above the calibrated threshold amount of energy.
