PROBLEM TO BE SOLVED: To prevent communication abnormality caused by connection of a plurality of communication devices employing different communication schemes to the same signal line in a charging communication system in which a charging control device performs inter-charging facility communication with an electric vehicle using a signal line within a charging cable.SOLUTION: In a charging communication system in which a charging control device performs inter-charging facility communication with an electric vehicle using a signal line within a charging cable, an electric vehicle 1 comprises: a first communication device 11 and a second communication device 12 that communicate with a charging facility 3 using the same signal line within a charging cable 2; and a signal line connection device 15 that switches connection/disconnection between the second communication device 12 and the signal line. A charging control device 13 for controlling a battery 10 in the electric vehicle 1 calculates a variation of signal line voltage between before and after the signal line connection device 15 connects the second communication device 12 to the signal line, and has the signal line connection device 15 disconnect the second communication device 12 from the signal line if the variation exceeds a prescribed permissible range.

    【課題】充電制御装置が充電ケーブル内の信号線を用いて電気自動車と充電設備間の通信を行う充電通信システムにおいて、異なる通信方式の複数の通信装置が同じ信号線に接続されることに起因する通信異常を防止する。【解決手段】充電制御装置が充電ケーブル内の信号線を用いて電気自動車と充電設備間の通信を行う充電通信システムにおいて、電気自動車1は、充電ケーブル2内の同一の信号線を用いて充電設備3との通信を行う第1通信装置11および第2通信装置12と、第2通信装置12と信号線との間の接続/切断を切り替える信号線接続装置15を備える。電気自動車1のバッテリ10を制御する充電制御装置13は、信号線接続装置15が第2通信装置12を信号線に接続させた前後における、信号線電圧の変化量を算出し、当該変化量が所定の許容範囲内に納まらなければ、信号線接続装置15により第2通信装置12を信号線から切断させる。【選択図】図1
