A wireless power supply device includes a marker provided closer to a side where a vehicle enters when parked than a power transmission coil unit housing a power transmission coil. The marker includes at least two segments not parallel to each other, and an end portion of one segment is connected to another segment. The power transmission coil is separated by a predetermined distance from a point of intersection of the two segments in a direction in which the one segment extends.

Parking assist device

Provided is a non-contact power supply device which detects foreign objects interposed between a power transmission coil and a power receiving coil. This non-contact power supply device is provided with a second coil which contactlessly transmits power to or receives power from a first coil at least by means of magnetic coupling, multiple sensors for detecting position shifts between the first coil and the second coil, a position detection means which, on the basis of the output values of the sensors, detects the relative positions of the first coil and the second coil, and a foreign object detection means which compares the output values of the sensors and from these comparison results detects foreign objects between first coil and the second coil.

Non-contact power supply device

This non-contact power supply system contactlessly supplies power by means of magnetic coupling between a power receiving coil () provided in a vehicle () and a power-transmission coil () on the power supply device () side. This non-contact power supply system is provided with a first communication means which wirelessly communicates between the vehicle () and the power supply device () in order to detect the distance therebetween, and a second communication means which performs wireless communication in order to detect the relative position of the power receiving coil () and the power transmission coil (). The second communication means is started when the distance between the vehicle () and the power transmission device (), measured by the first communication means, is shorter than a prescribed distance.

Non-contact power supply device, vehicle, and non-contact power supply system

A non-contact power supply apparatus includes a power receiving coil and transmits and receives power in a non-contact manner through magnetic coupling between the power receiving coil and a power transmitting coil included in a ground-side unit. The non-contact power supply apparatus includes: a remaining power detecting part configured to detect the remaining power of a battery; a charge start determining part configured to determine whether or not to start a charge operation of the battery, based on whether or not the remaining power of the battery detected by the remaining power detecting part is equal to or less than a charge start threshold; and a charge controlling part configured to start the charge operation if the charge start determining part determines that the charge operation is to be started.
