1. A vehicle information providing device is characterized by comprising:

  • a history information accumulation unit that sequentially acquires at least 1 type of information of travel position information, power consumption information, and charging facility information from an in-vehicle device of a vehicle that uses at least an electric motor as a drive source, and accumulates the information as travel history information;

    an input unit that inputs at least a departure point and a destination point;

    a planned route acquisition unit that acquires a planned route from the departure point to the destination point;

    a map storage unit that stores, based on the travel history information accumulated in the history information accumulation unit, a map obtained by associating an inter-charging facility route in which arbitrary 2 charging facilities belonging to a charging facility group including a plurality of charging facilities are connected to each other with a characteristic value including travel distance information, power consumption information, and travel time information related to power consumption of the motor when the vehicle travels on the inter-charging facility route;

    a history statistical processing unit that, when an end point of one of the plurality of travel routes accumulated in the history information accumulation unit is within a predetermined distance from an end point of the other travel route, connects the travel routes to each other by the end point to form a connection route, determines whether or not the connection route is a route that moves between charging facilities, and, when the connection route is a route that moves between charging facilities, creates the connection route as an inter-charging-facility route and accumulates the connection route in the travel history accumulation unit, and, when travel history information including an inter-charging-facility route equivalent to the inter-charging-facility route accumulated in the history information accumulation unit is accumulated, averages at least 1 of travel distance information, power consumption information, and travel time information included in the travel history information, updating the corresponding graph;

    a charging necessity determining unit that determines whether or not the vehicle needs to travel to the charging facility with reference to the travel history information accumulated in the history information accumulating unit when the vehicle travels from the departure point to the destination point, and determines the number of times of travel when the vehicle needs to travel to the charging facility; and

    a search unit that searches for a presentation route that is the same as or similar to the planned route acquired by the planned route acquisition unit with reference to the travel history information accumulated in the history information accumulation unit,when the charge necessity determining unit determines that the vehicle needs to travel to the charging facility, the search unit searches for a travel route from the departure point to a 1 st charging facility and a travel route from a 2 nd charging facility to the destination point, and then refers to the map stored in the map storage unit to select the combination of the inter-charging facility routes between the 1 st charging facility and the 2 nd charging facility.
