Abstract

A charging system and the charging method are provided. The charging system comprises a charging unit and a rechargeable unit. The rechargeable unit includes a first wireless communication apparatus and a first wireless charging module. The charging unit includes a second wireless communication apparatus, a second wireless charging module and a processing module. The charging method comprises the steps of: transmitting an authentication code and a charging signal to the second wireless communication apparatus by the first wireless communication apparatus; verifying the authentication code by the processing module after receiving the authentication code and the charging signal from the second wireless communication apparatus; charging the first wireless charging module via wireless charging by the second wireless charging module controlled by the processing module when the authentication code is verified.
