Abstract

A contactless charging system includes a target vehicle and a charging station. The charging station includes a power transmission device, at least one parking space, a restriction device, and a management device. The management device is configured to control the restriction device to be a second state in which the target vehicle is permitted to enter the charging station and the parking space when the target vehicle is the contactless charged vehicle, and to be a first state in which the target vehicle is restricted to enter the charging station or the parking space when the target vehicle is not the contactless charged vehicle.

First claim

What is claimed is:

1. A charging station comprising:
a power transmission device configured to transmit power to a contactless charged vehicle without contact;
at least one parking space in which the power transmission device is arranged;
a restriction device configured to be switched between a first state and a second state, the first state being a state of restricting entry of a target vehicle to one of the charging station and the parking space, the second state being a state of permitting the entry of the target vehicle to the charging station and the parking space, and the target vehicle being a vehicle that attempts to be parked in the at least one parking space; and
a management device configured to control the restriction device, the management device being configured to control the restriction device to be the second state when the target vehicle is the contactless charged vehicle, and the management device being configured to control the restriction device to be the first state when the target vehicle is a vehicle other than the contactless charged vehicle,
the management device is configured to receive information that is used to predict a parking use rate as a ratio of used spaces to total parking spaces from a server located on outside of the charging station, the information includes a rate of contactless charged vehicles and vehicles other than contactless charged vehicles that travel in an area within a specified distance from the charging station,
the management device is configured to predict the parking use rate to be a smaller value as the rate of contactless charged vehicles that travel within the specified distance is reduced, and
the management device is configured to control the restriction device to be the second state regardless of whether the target vehicle is the contactless charged vehicle when the management device determines that the parking use rate predicted in accordance with the information from the server is lower than a predetermined value.

2. The charging station according to claim 1 , wherein
the at least one parking space includes a plurality of parking spaces,
the restriction device is provided for each of the plurality of parking spaces,
the management device is configured to assign one of empty parking spaces among the plurality of parking spaces to the target vehicle when the target vehicle is the contactless charged vehicle,
the management device is configured to control the restriction device that is provided in the parking space assigned to the target vehicle to be the second state, and

the management device is configured to control the restriction device that is provided in the parking space other than the parking space assigned to the target vehicle among the empty parking spaces to be the first state.

3. A contactless charging system comprising:
a target vehicle that includes a contactless charged vehicle configured to receive power without contact; and
a charging station that includes a power transmission device, at least one parking space, a restriction device, and a management device, the target vehicle being a vehicle that attempts to be parked in the charging station,
the power transmission device being configured to transmit the power to the contactless charged vehicle without contact, and the power transmission device being arranged in the at least one parking space,
the restriction device being configured to be switched between a first state and a second state, the first state being a state of restricting entry of the target vehicle to one of the charging station and the parking space, and the second state being a state of permitting the entry of the target vehicle to the charging station and the parking space,
the management device being configured to control the restriction device, the management device being configured to control the restriction device to be the second state when the target vehicle is the contactless charged vehicle,
the management device being configured to control the restriction device to be the first state when the target vehicle is a vehicle other than the contactless charged vehicle,
the management device is configured to receive information that is used to predict a parking use rate as a ratio of used spaces to total parking spaces from a server located on outside of the charging station, the information includes a rate of contactless charged vehicles and vehicles other than contactless charged vehicles that travel in an area within a specified distance from the charging station,
the management device is configured to predict the parking use rate to be a smaller value as the rate of contactless charged vehicles that travel within the specified distance is reduced, and
the management device is configured to control the restriction device to be the second state regardless of whether the target vehicle is the contactless charged vehicle when the management device determines that the parking use rate predicted in accordance with the information from the server is lower than a predetermined value.

4. The contactless charging system according to claim 3 , wherein
the at least one parking space includes a plurality of parking spaces,
the restriction device is provided for each of the plurality of parking spaces,
the management device is configured to assign one of empty parking spaces among the plurality of parking spaces to the target vehicle when the target vehicle is the contactless charged vehicle,
the management device is configured to control the restriction device that is provided in the parking space assigned to the target vehicle to be the second state, and
the management device is configured to control the restriction device that is provided in the parking space other than the parking space assigned to the target vehicle among the empty parking spaces to be the first state.
