21. A vehicle propulsion system, comprising:
-
an electric battery configured to store electrical energy on-board the vehicle; a fuel tank configured to store fuel on-board the vehicle; an internal combustion engine configured to consume the fuel from the fuel tank to produce an engine output; an electric motor configured to consume the electrical energy from the electric battery to produce a motor output; and a control system configured to; periodically receive electrical energy from an electrical energy source located external the vehicle; discharge the energy storage device to operate the electric motor to produce the motor output; selectively operate the engine to combust fuel stored on-board the vehicle to produce the engine output; and increase engine operation based on whether a residence time of the fuel stored on-board the vehicle is greater than a threshold, the threshold adjusted responsive to ambient conditions and fuel composition. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
