Abstract

A vehicle electric power feeding system that is provided with an electric power feeding device (1A, 1B, 2A, 2B) that is provided at a location at which a vehicle (M) can stop; and a control means (3) that instructs the electric power feeding device (1A, 1B, 2A, 2B) to feed electric power to the vehicle in a stopped state (M: stopped vehicle) on the basis of a detection result of a detecting means (4) that detects the stopped state of the vehicle (M).

Claims

1. A vehicle electric power feeding system comprising:

an electric power feeding device configured to be provided at a location at which a vehicle can stop;

a detecting means configured to detect the stopped state of the vehicle according to a status signal indicating an operation state of an equipment operable for putting the vehicle in the stopped state;

upon receiving the status signal, the detecting means being configured to determine that the vehicle is in the stopped state, at a timing delayed by a predetermined time;

a control means configured to instruct the electric power feeding device to feed electric power to the vehicle in the stopped state on the basis of a detection result of the detecting means; and

a communicator configured to perform communication with the vehicle;

wherein the vehicle has the capability to communicate with the communicator;

the control means is configured to perform one or both of information exchange relating to one or both of the stopped state of the vehicle or to power feeding by the power feeding device, by performing communication with the vehicle via the communicator.

2. The vehicle electric power feeding system according to claim 1, wherein:

the electric power feeding device is provided with an electric power feeding coil;

the vehicle is provided with an electric power receiving coil; and

the electric power feeding device is configured to perform wireless electric power feeding to the vehicle by causing the electric power feeding coil to couple electromagnetically with the electric power receiving coil.

3. The vehicle electric power feeding system according to claim 1, wherein the location at which the vehicle can stop is one or both of a parking area of various kinds of facilities or houses, and a temporary stopping place of a public establishment or private establishment.
