Abstract

A controller of a contactless charging device performs a process including: acquiring vehicle information when a vehicle is present above a power transmitting device; permitting charging when it is determined that the vehicle is an electrically powered vehicle used as a taxi; starting charging; prohibiting charging when it is determined that the vehicle is not an electrically powered vehicle used as a taxi; and performing a notification process.

First claim

What is claimed is:

1 . A contactless charging device capable of contactlessly charging a power storage device mounted on an electrically powered vehicle used to provide a predetermined service, the electrically powered vehicle including a power receiving device that receives power from the contactless charging device, the contactless charging device comprising:
a power transmitting device, installed under the ground, which is capable of transmitting the power to the power receiving device when the electrically powered vehicle is stopped at a predetermined position in a stop space set as a standby site for the electrically powered vehicle; an acquisition device that acquires, from an external device external to the contactless charging device, information indicating that the electrically powered vehicle is stopped in the stop space; and a controller that controls the power transmitting device, wherein the controller determines, using the information acquired using the acquisition device, whether or not a vehicle stopped in the stop space is the electrically powered vehicle used to provide the predetermined service, when it is determined that the vehicle is the electrically powered vehicle used to provide the predetermined service, the controller permits transmission of power from the power transmitting device to the power receiving device, the external device includes an image capturing device, the image capturing device includes a first camera and a second camera, the first camera captures an image of an exterior portion of the vehicle stopped in the stop space, the second camera captures an image of a predetermined position of a lower surface of the vehicle stopped in the stop space, and when a characteristic portion of the electrically powered vehicle used to provide the predetermined service is included in the image of the exterior portion of the vehicle, as captured by the first camera, and a predetermined image of the power receiving device is included in the image of the predetermined position of the lower surface of the vehicle, as captured by the second camera, the controller determines that the vehicle stopped in the stop space is the electrically powered vehicle used to provide the predetermined service.

2 . The contactless charging device according to claim 1 , wherein when it is determined that the vehicle stopped in the stop space is not the electrically powered vehicle used to provide the predetermined service, the controller prohibits the transmission of power from the power transmitting device to the power receiving device.

3 . The contactless charging device according to claim 1 , wherein
the electrically powered vehicle is a taxi, and the power transmitting device is installed in the stop space set as a standby site for the taxi.

4 . The contactless charging device according to claim 1 , wherein
the electrically powered vehicle is a bus, and the power transmitting device is installed in the stop space set as a standby site for the bus.

5 . The contactless charging device according to claim 1 , wherein when it is determined that the vehicle stopped in the stop space is not the electrically powered vehicle used to provide the predetermined service, the controller notifies that the vehicle stopped in the stop space is not to be charged.

6 . A method of performing contactless charging by using a power transmitting device to transmit power to a power storage device mounted on an electrically powered vehicle used to provide a predetermined service, the electrically powered vehicle including a power receiving device that receives the power from the power transmitting device when the electrically powered vehicle is stopped at a predetermined position in a stop space set as a standby site for the electrically powered vehicle, the method comprising:
acquiring, from an external device, information indicating that the electrically powered vehicle is stopped in the stop space; determining, using the acquired information, whether or not a vehicle stopped in the stop space is the electrically powered vehicle used to provide the predetermined service; and permitting transmission of power from the power transmitting device to the power receiving device when it is determined that the vehicle stopped in the stop space is the electrically powered vehicle used to provide the predetermined service, wherein the acquiring information, from an external device, includes: capturing, via a first camera of the external device, an image of an exterior portion of the vehicle stopped in the stop space, and capturing, via a second camera of the external device, an image of a predetermined position of a lower surface of the vehicle stopped in the stop space, and the determination that the vehicle stopped in the stop space is the electrically powered vehicle used to provide the predetermined service is made when a characteristic portion of the electrically powered vehicle used to provide the predetermined service is included in the image of the exterior portion of the vehicle, as captured by the first camera, and a predetermined image of the power receiving device is included in the image of the predetermined position of a lower surface of the vehicle, as captured by the second camera.
