1. A method of adjusting operation of a drivetrain of a vehicle, the drivetrain comprising an engine, an e-axle, a battery system, and a motor/generator coupled to the e-axle and operable as a motor to receive electric power from the battery system to supply rotational power through the e-axle and as a generator to receive rotational power from the e-axle to generate electric power to charge the battery system, the method comprising:
determining a route of the vehicle;
determining a drivetrain configuration for the vehicle over the route;
determining a starting state of charge (SOC) of the battery system for a portion of the route;
determining a target end SOC of the battery system at an end of the portion of the route;
calculating, based on the starting SOC of the battery system and the drivetrain configuration of the vehicle, a predicted end SOC of the battery system at the end of the portion of the route;
determining whether the predicted end SOC of the battery system will be less than the target end SOC of the battery system; and
determining a performance plan for the vehicle, the performance plan including a set of instructions causing the vehicle to change the drivetrain configuration based on a comparison of the predicted end SOC of the battery system with the target end SOC of the battery system, wherein changing the drivetrain configuration comprises lowering the e-axle to a down position such that a set of wheels coupled to the e-axle contact a road surface, or raising the e-axle to an up position such that the set of wheels coupled to the e-axle do not contact the road surface.
