A battery level management system for an electric vehicle during a powered down and uncharged period is disclosed. A current output from a low voltage battery of the electric vehicle being above a threshold can be sensed to wake up a control unit associated with the low voltage battery without waking up or fully powering other control units. Upon waking up, the control unit associated with the low voltage battery can start monitoring the current output from the low voltage battery and controlling the power drawn from the low voltage battery by enabling or disabling other control units to manage the remaining low voltage battery power level.
