The invention relates to the technical field of energy storage charging, in particular to a direct current charging pile internal communication method and system, and the system comprises a communication module in a charging gun and a control module in a charging pile. A power line communication terminal of the charging gun is connected with the control module through a power line; the controller obtains first data information sent by the low-voltage auxiliary power supply terminal and sends the first data information to the carrier module; the carrier module modulates the first data information into a first high-frequency carrier signal, couples the first high-frequency carrier signal to a power line communication terminal for transmission, demodulates second data information and transmits the second data information to the controller; the filter filters a high-frequency carrier signal loaded in the current and shunts the current to the low-voltage auxiliary power supply terminal and the DC/DC isolation power supply; the DC/DC isolation power supply converts the voltage shunted by the filter into the power supply voltage of the controller; according to the invention, the functions of power supply and communication are simultaneously realized, and the material and maintenance cost is reduced.

    本发明涉及储能充电技术领域,具体为一种直流充电桩内部通讯方法及系统,系统包括充电枪中的通讯模块和充电桩中的控制模块;充电枪的电力线通信端子与控制模块通过电力线连接;控制器获取低压辅助电源端子发送的第一数据信息并发送给载波模块;载波模块将第一数据信息调制为第一高频载波信号后耦合到电力线通信端子进行发送,以及解调出第二数据信息后发送给控制器;滤波器过滤电流中加载的高频载波信号,将电流分流给低压辅助电源端子和DC/DC隔离电源;DC/DC隔离电源将滤波器分流的电压转换为控制器的供电电压;本发明同时实现了供电和通讯的功能,减少了材料和维护成本。
