Abstract

An object is to guide an electric vehicle that needs to be charged before reaching a destination to an appropriate charging station and prevent the electric vehicle from stopping due to battery exhaustion. A control center 1 detects a predetermined electric vehicle that needs to be charged to reach a destination from the current location, based on predetermined electric vehicle information acquired from electric vehicles, detects a predetermined charging station available for the predetermined electric vehicle from among a plurality of charging stations, based on predetermined charging station information and predetermined electric vehicle information on the predetermined electric vehicle, detects a predetermined path for guiding the predetermined electric vehicle to the predetermined charging station, and transmits predetermined guidance information including the predetermined path to the predetermined electric vehicle.

Claims

acquire predetermined charging station information related to a device state and a use state of the vehicle from among a plurality of charging stations via the information collector;

detect a predetermined electric vehicle that needs to be charged to reach a destination from a current location, based on the predetermined electric vehicle information acquired from each of the plurality of the electric vehicles via the information collector;

detect a plurality of predetermined charging stations available for the predetermined electric vehicle from among the plurality of the charging stations, based on the predetermined charging station information and the predetermined electric vehicle information;

select one predetermined charging station from among the plurality of predetermined charging stations based on a sum of arrival time of the predetermined electric vehicle arriving at the predetermined charging station and time required for charging at the predetermined charging station, and possibility of the predetermined electric vehicle arriving at the predetermined charging station, and detect a predetermined path for guiding the predetermined electric vehicle to the selected predetermined charging station; and

transmit predetermined guidance information including the predetermined path to the predetermined electric vehicle.

2. The charging support system for an electric vehicle according to claim 1, wherein

the controller can detect a plurality of predetermined electric vehicles simultaneously, and

detects the predetermined charging station and the predetermined path for each of the plurality of the predetermined electric vehicles and then transmits them to each of the plurality of the predetermined electric vehicles.

3. The charging support system for an electric vehicle according to claim 2, wherein the controller displays the position and power storage amount of the predetermined electric vehicle, the position and number of vehicles for which charging is reserved at the predetermined charging station, and the predetermined path overlapped on a map.

4. The charging support system for an electric vehicle according to claim 3, wherein from among the plurality of charging stations, the controller manages charging stations within a predetermined distance as stations belonging to a single group, and selects the predetermined charging station from the group.

5.
