Abstract
Methods and apparatus are provided for performing a jump-start without the use of external equipment. The apparatus comprises a first battery electrically coupled to a starter motor for an engine, the first battery providing power to start the engine; a second battery; a power converter electrically coupled to the first battery and electrically coupled to the second battery; and a controller communicatively coupled to the power converter. The controller may be configured to determine a low battery condition of the first battery such that the first battery has insufficient power to start the engine, and when the low battery condition occurs, to direct the power converter to supply power from the second battery to the first battery to thereby allow the engine to be started.
