The embodiment of the invention discloses a signal transmission circuit, a charging pile and a charging vehicle. A connection port, a wire, a carrier module and a coupling module are arranged in a vehicle or a charging pile, the wire is connected with the connection port and is configured to transmit an electric signal, and the coupling module is connected between the wire and the carrier module and is configured to receive a carrier signal from the wire and send the carrier signal to the carrier module, and/or send the carrier signal to the charging pile. A carrier signal is received from the carrier module and sent to the wire. Therefore, carrier communication can be carried out through the carrier module by using the lead, accurate control between the carrier module and the carrier module is realized, cost is reduced, and communication efficiency and precision are improved.
本发明实施例公开了一种信号传输电路、充电桩和充电车辆。通过在车辆或充电桩中设置连接端口、导线、载波模块和耦合模块,导线与连接端口连接,被配置为传输电信号,耦合模块连接在导线和载波模块之间,被配置为从导线上接收载波信号并发送给载波模块,和/或,从载波模块接收载波信号并发送至导线。由此,可以通过载波模块利用导线进行载波通信,实现两者之间的精确控制,降低成本,提升通信效率和精度。
