Energy Consumption Calculation Device, and Energy Consumption Calculation Method of Same

An energy consumption calculation method for use in an energy consumption calculation device, comprising:

• an energy consumption estimation step of estimating, by the energy consumption calculation device, an energy consumption in a predetermined section;
• an actual energy consumption identification step of identifying, by the energy consumption calculation device, an actual energy consumption that is actually supplied in the predetermined section by energy supply unit adapted to supply energy;
• an energy consumption correction step of correcting, by the energy consumption calculation device, the energy consumption in the predetermined section estimated in the energy consumption estimation step in accordance with a difference between the energy consumption in the predetermined section estimated in the energy consumption estimation step and the actual energy consumption in the predetermined section identified in the actual energy consumption identification step;
• and
• a display step of identifying and displaying, by the energy consumption calculation device, by using the energy consumption in the predetermined section corrected in the energy consumption correction step, a possible travel range by which travel is possible with a suppliable energy amount of the energy supply unit.
