Abstract

A computer-implemented method of displaying vehicle range includes receiving input corresponding to a level of charge remaining in a vehicle having at least a partial electric power source usable for vehicle locomotion. The method also includes determining a maximum remaining range which the vehicle can travel based at least on the level of charge. The method further includes displaying a maximum range boundary overlaid on a map, including at least an indicator at the center of the range indicating a current location of the vehicle.
