Abstract

A feeding apparatus includes a feeding unit configured to feed power in a non-contact manner to the charging apparatus mounted on a vehicle and a feeding control unit that receives vehicle detection information from a sensor configured to transmit vehicle detection information when a vehicle is detected. The apparatus executes control so that the feeding unit provided in the feeding apparatus feeds first power determined for each feeding apparatus so as to specify the feeding apparatus, transmits charging start information indicating a start of charging when feeding unit specifying information containing information to indicate the power level at which power is received from the feeding unit is received from the charging apparatus, and the received power level is determined to be within a specific power range, and executes control so that the feeding unit feeds second power in order to charge a battery unit of the charging apparatus.

Claims

the feeding control unit makes the feeding unit output the first power of a magnitude corresponding to the feeding unit in order to specify the feeding unit, acquires, through the radio communication unit, feeding unit specifying information transmitted by the vehicle which has received the first power, determines whether or not the magnitude of the power indicated by the feeding unit specifying information is within a specific power range stored in advance, and transmits to the vehicle charging start information to start charging when determining that the magnitude is within the specific power range, and controls the feeding unit specified by the feeding unit specifying information so that it outputs the second power.

2. The feeding apparatus according to claim 1, wherein

the feeding control unit starts output of the first power corresponding to the feeding unit, when receiving the vehicle detection information from a vehicle detection sensor provided outside via the radio communication unit.

3. The feeding apparatus according to claim 1, further comprising:

a first device including the one or plurality of feeding units, and the one or plurality of feeding control units each associated with each of the feeding units; and

the radio communication unit configured to perform radio communication with each feeding control unit and arranged separately from the first device.

4. The feeding apparatus according to claim 1, further comprising:

a second device including the radio communication unit and the feeding control unit; and

the one or plurality of feeding units arranged separately from the second device, and configured to be controlled by the feeding control unit.

5. The feeding apparatus according to claim 1, wherein

the feeding control unit performs control so that the feeding unit in preparation for power feeding or during power feeding does not feed the first power, when the charging apparatus is in preparation for charging or is charging.

6. A charging apparatus used for non-contact charging and mounted on a vehicle, the charging apparatus mounted on the vehicle comprising:
