<P>PROBLEM TO BE SOLVED: To provide a power line communication system with mixed power line communication devices having different configurations. <P>SOLUTION: A charging stand 5 performs power line communication by using a signal superposition separation part having a configuration 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 by using a signal superposition separation part having a configuration in which a coupling transformer 15 is located on one AC line 11, and a capacitor 16 is connected to between two AC lines 11 and 12. These configurations enable power line communication in the case that the charging stand 5 and the electric vehicle 1 are connected with a charge cable, because a closed loop circuit is formed by 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 the coupling transformer 15, the AC line 11, and an AC line 71. <P>COPYRIGHT: (C)2012,JPO&INPIT |
