Determination and display of expected range of vehicle having electric traction motor

A method of determining a selected duration of an initial cool-down or heat-up of a climate control of a vehicle having an electric traction motor, the method comprising:

• during the selected duration, calculating an expected range of the vehicle referencing an average power consumption of the climate control system during the initial cool-down or heat-up of the climate control system;
• after the selected duration, calculating the expected range of the vehicle referencing an actual power consumption of the climate control system to maintain operation of the climate control system;
• and
• displaying the expected range on a display located in a passenger cabin of the vehicle.

A device for a vehicle having at least an electric traction motor and a passenger cabin, the device comprising:

• a memory storing an expected range routine;
• and
• a processor coupled to the memory, the processor configured to execute the expected range routine to:
• determine an average power consumption of a cabin conditioning system over a selected duration of initial cabin conditioning by the cabin conditioning system;
• during the selected duration of initial cabin conditioning, add the average power consumption of the cabin conditioning system to an instantaneous power consumption of at least the electric traction motor to determine a total power consumption of the vehicle;
• use the total power consumption of the vehicle to determine the expected range of the vehicle;
• and output the expected range of the vehicle to a display.
