A wireless charging system includes a power transmitting module and a power receiving module. The power transmitting module includes a first charging head and a plurality of first coils which are located on the first charging head and connected in parallel with each other. The power receiving module includes a second charging head and a plurality of second coils which are located on the second charging head and connected in parallel with each other. Thus, when the first charging head docks to the second charging head, each of the first coils faces to one of the second coils.

A position alignment method comprises recognizing the state of the plurality of GAs through wireless communication with an SECC for controlling the plurality of GAs, receiving information about one or more valid GAs among the plurality of GAs from the SECC, selecting a target GA on the basis of the information about the one or more valid GAs, and establishing a wireless communication link; making a request to the SECC for performing a position alignment approval and authentication process, performing position alignment with the target GA using an LF signal if the authentication is successful, transmitting a dataset to the SECC using the LF signal after the position alignment with the target GA, and pairing with the target GA based on the dataset.

A communication device of a vehicle transmits a charging permission request message to a server and receives charging permission information from the server. A charging requester is configured to transmit a charging request message including the charging permission information to a charging device and a power receiver is configured to receive a charging response message from the charging device and to wirelessly receive power from the charging device.

The current invention concerns a method for wireless power transfer from a charging station to an energy storage element of an AGV, or on an AGV. Furthermore, it provides a charging station, as well as a wireless energy receiving system for receiving energy from a charging station and providing said received energy to an energy storage element of an AGV, or on an AGV, and furthermore a system for wireless power transfer incorporating one or more charging stations and a plurality of said wireless energy receiving systems.
