  "textContent": "Provided is a communication system in which devices having different structures and related to communications are coexistent. A charging station (2) performs communications by use of a superimposing/separating unit configured by connecting a capacitor (221), a coupling transformer (153) and a capacitor (222) to branch lines (33a, 34a) branching out respectively from a control cable (33) and a grounded cable (34). An electric vehicle (1) performs communications by use of a superimposing/separating unit configured by providing a coupling transformer (131) to the control cable (33). A capacitor (121) is also connected between the control cable (33) and the grounded cable (34). Communications are allowed by the configuration of a closed loop circuit comprising the control cable (33), the branch line (33a), the capacitor (221), a primary coil (223a) of the coupling transformer (223), the capacitor (222), the branch line (34a), the grounded cable (34), the capacitor (121), and a primary coil (131a) of the coupling transformer (131).",
