Abstract: A charging system includes a source terminal and a sink terminal. The control method of the charging system includes transmitting a bus voltage by the source terminal, determining whether the sink terminal has entered a sink attached state when the sink terminal receives the bus voltage, enabling a message transceiver of the sink terminal if the sink terminal has entered the sink attached state, transmitting a source message to the transceiver of the sink terminal by the source terminal, transmitting a request message to the source terminal by the message transceiver of the sink terminal while the source terminal transmits the source message, and continuing to enable a communication function for communicating with the sink terminal and continuing to transmit the bus voltage to the sink terminal by the source terminal when the source terminal receives the request message.
