Electric power reception device for vehicle, electric power transmission device, and non-contact electric power transmission/reception system
An electric power reception device for a vehicle is equipped with an electric power reception unit that is configured to be able to receive electric power from an electric power transmission device in a non-contact manner, a communication portion that transmits information on a position or dimension of the electric power reception unit to the electric power transmission device, and a vehicle ECU that controls the communication portion. Preferably, the vehicle ECU transmits pre-stored information to the electric power transmission device with the aid of the communication portion, before allowing a vehicle to be parked at an electric power reception position of the electric power transmission device. The information includes at least one of a size of the electric power reception unit, a size of the vehicle in which the electric power reception unit is mounted, and a mounting position of the electric power reception unit in the vehicle.
1. An electric power reception device for a vehicle that can receive electric power from an electric power transmission device outside the vehicle in a non-contact manner, the electric power reception device comprising:
an electric power reception unit configured to receive electric power from the electric power transmission device in a non-contact manner;
a communication portion configured to receive information on a physical size of the electric power transmission unit from the electric power transmission device; and
a control device configured to determine whether or not non-contact charging is possible based on the information received by the communication portion.
2. The electric power reception device according to claim 1 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about whether or not non-contact charging is possible based on the information; and
notify a passenger of the determination result.
3. The electric power reception device according to claim 1 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about a guidance direction of the vehicle based on the information; and
notify a passenger of the determination result.
4. The electric power reception device according to claim 1 , wherein:
the vehicle includes a plurality of electric power reception units, and
the control device is further configured to use the information to determine which of the plurality of electric power reception units is used to receive electric power.
5. The electric power reception device according to claim 1 , wherein:
the vehicle includes a movable electric power reception unit; and
the control device is further configured to use the information to determine a position of the electric power reception unit.
6. An electric power reception device for a vehicle that can receive electric power from an electric power transmission device in a non-contact manner, wherein
the electric power transmission device includes an electric power transmission unit that transmits electric power to the vehicle, and transmits information on a position or dimension of the electric power transmission unit to the electric power reception device for the vehicle,
the electric power reception device comprising:
a communication portion that receives information on a physical size of the electric power transmission unit from the electric power transmission device;
an electric power reception unit configured to receive electric power from the electric power transmission unit in a non-contact manner; and
a control device configured to determine whether or not non-contact charging is possible based on the information received by the communication portion.
7. The electric power reception device according to claim 6 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about whether or not non-contact charging is possible based on the information; and
notify a passenger of the determination result.
8. The electric power reception device according to claim 6 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about a guidance direction of the vehicle based on the information; and
notify a passenger of the determination result.
9. A non-contact electric power transmission/reception system comprising:
an electric power reception device mounted in a vehicle; and
an electric power transmission device located outside the vehicle;

a communication portion configured to receive information on a physical size of the electric power transmission unit from the electric power transmission device, and
a control device configured to determine whether or not non-contact charging is possible based on the information received by the communication portion.
10. The non-contact electric power transmission/reception system according to claim 9 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about whether or not non-contact charging is possible based on the information; and
notify a passenger of the determination result.
11. The non-contact electric power transmission/reception system according to claim 9 , wherein the control device is further configured to:
receive, from the electric power transmission device, a determination result about a guidance direction of the vehicle based on the information; and
notify a passenger of the determination result.
