1. A method for managing a state of charge (SoC) of an energy store of a vehicle comprising:
storing a machine-readable encoding of a dynamic weight value that specifies a usage of a fuel-fed engine relative to a usage of the energy store, wherein the fuel-fed engine powers a drivetrain that provides primary motive forces to the vehicle, wherein the energy store is configured to supply electrical power to an electrically powered drive axle that provides supplemental torque to one or more wheels of the vehicle in a first mode of operation, and wherein the energy store is configured to receive energy recovered using the electrically powered drive axle in a second mode of operation;
computationally determining an estimated travel time to a stopover location based in part on a distance between a current GPS location of the vehicle and the stopover location;
using the estimated travel time, modifying the dynamic weight value to provide an updated dynamic weight value; and
responsive to providing the updated dynamic weight value, increasing the SoC of the energy store while the vehicle travels over a roadway to provide a target SoC of the energy store when the vehicle arrives at the stopover location.
