Abstract

Each time the charging of an electric vehicle is executed at a charging station, charging information is acquired which is information on a charged capacity by one charging or a time required for one charging, and identification information of the electric vehicle is acquired. Each charging time, the acquired charging information and the acquired identification information are stored in an information storage unit so that they are associated with each other. The identification information of an electric vehicle is acquired which is waiting for charging at a charging station as a calculation object for which a charging wait time is calculated. The charging information corresponding to the acquired identification information of the electric vehicle waiting for charging is extracted from the stored charging information. The charging wait time at the charging station as the calculation object is calculated on the basis of the extracted charging information.

First claim

The invention claimed is:

1. A charging wait time calculation system comprising:
a first camera and a second camera;
the second camera configured to acquire identification information of a first electric vehicle each time charging of the first electric vehicle is executed at a charging station;
the first camera configured to acquire identification information of one or more second electric vehicles waiting for charging at the charging station as a first calculation object for which a charging wait time for the one or more second electric vehicles is calculated;
a display panel disposed in the charging station; and
a server comprising:
a communication device configured to acquire first charging information of the first electric vehicle each time charging is executed at the charging station, the first charging information acquired via a charger and being information regarding a charged capacity or a time required for charging;
an information storage device in which the first charging information acquired by the communication device and the identification information acquired by the second camera are stored so as to be associated with each other;
an information extraction device configured to extract the first charging information corresponding to the identification information by the first camera as second charging information from the stored charging information in the information storage device; and
a charging wait time calculator configured to calculate the charging wait time at the charging station as a second calculation object on a basis of the second charging information extracted by the information extraction device, and transmit the calculated charging wait time to the display panel,
wherein the charging wait time calculator calculates a sum of a remaining charging time for the first electric vehicle being charged at the charging station as a third calculation object and each charging time for each of the one or more second electric vehicles waiting for charging at the charging station as a fourth calculation object.

2. The charging wait time calculation system according to claim 1 , wherein the charging wait time calculator calculates the charging wait time on a basis of an average value, a median value, a mode value, or a latest value of the capacity or the time included in the charging information extracted by the information extraction device.

3. The charging wait time calculation system according to claim 1 , wherein,
each time charging of an electric vehicle is executed at a charging station, the information storage device is configured to store the first charging information acquired by the communication device, information on a classification of a date on which the charging is executed, and the identification information acquired by the second camera so that these information items are associated with one another, and
the information extraction device is configured to extract the second charging information from the stored charging information in the information storage device, wherein the second charging information corresponds to the identification information acquired by the first camera and corresponds to the classification of a date on which the charging wait time is calculated.

4. The charging wait time calculation system according to claim 1 , wherein,
each time charging of an electric vehicle is executed at a charging station, the information storage device is configured to store the first charging information acquired by the communication device, information on a temperature zone of external air when executing the charging, and the identification information acquired by the second camera so that these
information items are associated with one another, and the information extraction device is configured to extract the second charging information from the stored charging information in the information storage device, wherein the second charging information corresponds to the identification information acquired by the first camera and corresponds to the temperature zone of external air when calculating the charging wait time.

5. The charging wait time calculation system according to claim 1 , wherein,
each time charging of an electric vehicle is executed at a charging station, the information storage device is configured to store the first charging information acquired by the communication device, information on an area in which the charging is executed, and the identification information acquired by the second camera so that these information items are associated with one another, and
the information extraction device is configured to extract the second charging information from the stored charging information in the information storage device, wherein the second charging information corresponds to the identification information acquired by the first camera and corresponds to the area of the charging station as a fifth calculation object.

6. The charging wait time calculation system according to claim 1 , wherein,
each time charging of an electric vehicle is executed at a charging station, the information storage device is configured to store the first charging information acquired by the communication device, information on an output of a charger, and the identification information acquired by the second camera so that these information items are associated with one another, and
the information extraction device is configured to extract the second charging information from the stored charging information in the information storage, wherein the second charging information corresponds to the identification information acquired by the first camera and corresponds to the output of the charger waiting for charging.

7. The charging wait time calculation system according to claim 1 , wherein,
each time charging of an electric vehicle is executed at a charging station, the information storage device is configured to store the first charging information acquired by the communication device, information on a rated capacity of a battery of the electric vehicle, and the identification information acquired by the second camera so that these information items are associated with one another, and
when the second charging information corresponding to the identification information acquired by the second camera is not stored in the information storage, the information extraction device is configured to extract a third charging information of another electric vehicle from the stored charging information in the information storage device, wherein the third charging information of another electric vehicle corresponds to the rated capacity of the battery of the electric vehicle corresponding to the identification information acquired by the first camera.

8. The charging wait time calculation system according to claim 1 , wherein each of the first and second cameras is configured to image a license plate of an electric vehicle, wherein the server further comprises:
an identification information storage device configured to store the identification information of the electric vehicle in association with a number of the license plate;
a number detector configured to detect the number of the license plate from imaging information of each of the first and second cameras; and
an identification information extraction device configured to extract the identification information from the stored charging information in the identification information storage, wherein the identification information corresponds to the number detected by the number detector.

9. The charging wait time calculation system according to claim 1 , wherein the identification information of an electric vehicle is acquired from the first and second camera
