The invention discloses an electric vehicle charging equipment communication mode, which is characterized in that communication between a charging pile body and a charging terminal is realized through a power line carrier communication PLC, the charging terminal transmits charging energy information required by an electric vehicle to the charging pile body through the power line carrier communication PLC, and the charging pile body transmits the charging energy information required by the electric vehicle to the charging pile body according to the received information. And meanwhile, the adjusted information is transmitted back to the charging terminal through the power line carrier communication PLC, and the charging terminal and the power line carrier communication PLC can communicate with each other. A traditional CAN communication mode between the charging pile body and the charging terminal is changed into a power line carrier PLC communication mode, the traditional charging pile body and the charging terminal are provided with two alternating-current 220V wires L and N, and the traditional charging pile body and the charging terminal are provided with two alternating-current wires for communication, so that previous CAN communication is replaced; a CAN wire harness is omitted, the cost is saved, and meanwhile, the wiring mode and the construction mode of the charging pile body and the charging terminal become simpler, more convenient and more diversified.

    本申请公开了一种电动汽车充电设备通讯方式,其通过电力线载波通讯PLC实现充电堆本体和充电终端的通讯,充电终端将电动汽车需求的充电能量信息通过电力线载波通讯PLC传递给充电堆本体,充电堆本体根据接收到的信息,调整能量的输出,同时将调整的信息通过电力线载波通讯PLC回传给充电终端,两者之间可以互相通讯。本申请将传统的充电堆本体和充电终端之间的CAN通讯方式改为电力线载波PLC通讯方式,传统的充电堆本体和充电终端本身就存在两根交流220V导线L和N,利用传统的充电堆本体和充电终端本身就存在两根交流导线进行通讯,从而取代之前的CAN通讯,取消了CAN线束,节约成本,同时使得充电堆本体和充电终端的布线方式和施工方式变得更加简便多样化。
