1. A navigation device for an electric vehicle comprising:
- at least one processor configured as a route search unit, wherein the route search unit searches for at least one route, to a predetermined destination, which is to be traveled by an electric vehicle propelled only by electric power stored in a secondary battery provided within the vehicle;
a recording unit including gradient information for a road recorded therein;
a power information holding unit including electrical power consumption information of the electric vehicle per gradient angle and regenerative electrical energy information of the electric vehicle per gradient angle;
a current location acquisition unit including a current location of the electric vehicle;
a navigation control unit,wherein the navigation control unit calculates electrical power consumption of the electric vehicle when a route to a destination, which was searched for by the route search unit, is traveled by the electric vehicle, based on information on electric power to be consumed when the electric vehicle travels and geographical information relating to the route, and calculates an amount of electrical power which needs to be reduced to reach the destination; and
wherein the navigation control unit further calculates electrical power consumption of the electric vehicle, based on the gradient information, the electrical power consumption information of the electric vehicle per gradient angle and the regenerative electrical energy of the electric vehicle per gradient angle, the power consuming device'"'"'s operation time in the route, in addition to the information on electric power to be consumed and the geographical information; and
a display configured to display a route to the predetermined destination with a least electrical power consumption to the predetermined destination,wherein the at least one processor is configured to cause the display to display a total calculated electrical power consumption required for the entirety of the at least one route, the amount of calculated electrical power which needs to be reduced to reach the destination, and at least one countermeasure to reduce an amount of electrical power being consumed by a power consuming device other than a driving unit.
