摘要： Provided are a communication system and a communication apparatus that can prevent a function of recognizing the status between a feeding apparatus and a vehicle, which use output and input circuits, from being lost even when a communication signal is carried on a control pilot line. An output circuit (20) sends out, to an input circuit (60), a control pilot signal generated by a voltage source (21). A voltage transformer (31) is provided to a control pilot line (4) on the output side of the output circuit (20), and a communication unit (30) transmits and receives communication signals via the voltage transformer (31). A voltage transformer (71) is provided to the control pilot line (4) on the input side of the input circuit (60), and a communication unit (70) transmits and receives the communication signals via the voltage transformer (71). A low-pass filter (73) is provided to the control pilot line (4) between the input circuit (60) and the voltage transformer (71).

摘要： A plurality of power transmitters (31) in this non-contact charging system each supply electric power in a noncontact manner to devices to be charged (20). Acommunication section (12) is configured to be capable of acquiring information transmitted from each device to be charged. A power supply control section (11) controls, on a per-power-transmission-unit basis, the electric power to be transmitted by each power transmitter. The presence of a device to be charged is detected, and in response to the detection of the presence of the device to be charged, the power supply control section sets, to a specific pattern, the pattern of electric power to be transmitted from the power transmission unit. The specific pattern differs for every power transmission unit. The communication section receives information about a specific pattern as transmitted from the device to be charged. The device to be charged acquires the specific pattern from the received electric power. The power transmission unit and the device to be charged corresponding to the power transmission unit form a combination. The power supply control section identifies the combination between the power transmission unit and the device to be charged based on correspondence between information about the specific pattern that has been set, and the received information about the specific pattern.
