Abstract
A method of externally charging a powertrain includes monitoring a voltage level of a first battery, determining when the monitored voltage level is below a first voltage threshold, and when the monitored voltage level is below the first voltage threshold, charging the first battery by supplying power from an external power source and increasing voltage of the power supplied by the external power source within the powertrain.
