  "textContent": "Provided is a power line communication system in which power line communication devices having different configurations from each other coexist. A charging station 5 performs power line communication, using a signal superimposition/separation section in which a capacitor 56, a coupling transformer 55, and a capacitor 57 are connected to branch lines 51a and 52a branched from two AC lines 51 and 52. An electric vehicle 1 performs power line communication, using a signal superimposition/separation section in which the coupling transformer 56 is inserted in one AC line 11 and a capacitor 16 is connected to and between two AC lines 11 and 12. In a case where the charging station 5 and the electric vehicle 1 are connected to each other with a charging cable, a closed loop circuit is formed that is composed of the AC line 51, the branch line 51a, the capacitor 56, a primary coil 55a of the coupling transformer 55, the capacitor 57, the branch line 52a, the AC line 52, an AC line 72, the AC line 12, the capacitor 16, a primary coil 15a of a coupling transformer 15, the AC line 11, and an AC line 71. Thus, power line communication can be performed.",
