1. A vehicle, comprising:
at least one electrically-powered drive axle;
an electric motor/generator (M/G) coupled to the electrically-powered drive axle;
a battery management system (BMS) comprising one or more batteries, wherein the battery management system is configured to:
identify an upcoming uphill grade or upcoming downhill grade; and
selectively supply electrical power to the M/G in a first mode of operation to provide a motive force to the vehicle when traveling on the upcoming uphill grade, wherein the M/G is configured to provide a motive force in the first mode of operation to supplement a motive force provided through a primary drivetrain of the vehicle, or selectively receive energy recovered from the M/G in a second mode of operation when traveling on the upcoming downhill grade to maintain a desired state-of-charge (SoC) of the one or more batteries during over-the-roadway travel.
