Abstract
A control system for an electrified vehicle having low and high voltage battery systems includes a set of vehicle modules that collectively draw an ignition-off draw (IOD) current from the low voltage battery system while the vehicle is off, a set of sensors configured to measure a set of parameters of at least one of the low and high voltage battery systems, and a controller configured to: estimate the IOD current, receive the set of measured parameters from the set of sensors, based on the set of measured parameters and the estimated IOD current, set a wakeup time indicative of a future time at which the low voltage battery system will require recharging, and based on the wakeup time, temporarily wakeup the vehicle such that recharging of the low voltage battery system using the high voltage battery system is enabled.
