Classification: CPC B  Y | IPC B

Claim 0:
1. A method of predicting a range of an electric vehicle, the method comprising:
a sensor determining whether a trailer is attached to the vehicle,
a vehicle supervisory controller determining an energy gradient value indicative of an energy consumption of the vehicle during a current vehicle operating cycle, the energy gradient value being determined based on:
if it is determined that the trailer is not attached to the vehicle, a calculated energy gradient for the current vehicle operating cycle and a first stored energy gradient value indicating an energy consumption rate of the vehicle during a previous vehicle operating cycle in which a trailer was not attached to the vehicle; or
if it is determined that the trailer is attached to the vehicle, the calculated energy gradient for the current vehicle operating cycle and a second stored energy gradient value indicating an energy consumption rate of the vehicle during a previous vehicle operating cycle in which a trailer was attached to the vehicle,

the vehicle supervisory controller determining a first range value based on the determined energy gradient indicative of the energy consumption of the vehicle during the current vehicle operating cycle, and
a display interface displaying a range metric to a user of the electric vehicle, the range metric being based on the determined first range value.
