PROBLEM TO BE SOLVED: To stably achieve three types of communication, i.e. "Inband communication", "PLC communication" and "charge control by a CPLT signal", with a simple structure, in regard to an Inband communication/PLC communication interconnection device in a vehicle charging system.SOLUTION: A reception controller sets to be a reception standby state for detecting a communication signal through an Inband side switch SW-I and a PLC side switch SW-P. On detection of an Inband communication signal, the reception controller switches on the SW-I and switches off the SW-P, to control a modem unit 103-2 to receive an Inband communication signal from a vehicle 101. On detection of a power line communication signal, the reception controller switches off the SW-I and switches on the SW-P, to control the modem unit 103-2 to receive a power line communication signal from an external network. |
