1. A noncontact charging system comprising a charging apparatus installed in a vehicle and one or more charging stations, each of the charging stations comprising:
- a power feeding apparatus that supplies power to the charging apparatus;
a power feeding apparatus wireless communication unit provided in the power feeding apparatus in order to perform wireless communication; and
a power feeding apparatus noncontact communication unit provided in the power feeding apparatus in order to perform noncontact communication,the charging apparatus comprising;
a charging apparatus wireless communication unit in order to perform the wireless communication; and
a charging apparatus noncontact communication unit in order to perform the noncontact communication,wherein the wireless communication can be performed between the charging apparatus and the one or more power feeding apparatuses, and the noncontact communication can be performed between the charging apparatus and only one of the one or more power feeding apparatuses, and wherein an ID determined individually for each vehicle or each charging station is transmitted and received by the wireless communication, the ID is transmitted and received by the noncontact communication, and the noncontact charging system compares the ID which is transmitted and received by the wireless communication with the ID which is transmitted and received by the noncontact communication, whereby, the noncontact charging system specifies a power feeding apparatus which should perform the wireless communication to the charging apparatus, from the one or more power feeding apparatuses and establishes a wireless communication between the power feeding apparatus and the charging apparatus.
