The invention relates to a charging pile input PE detection system, a charging pile and a charging system.The input PE detection system comprises a voltage reduction module, an anti-surge module, a voltage stabilization module, a current limiting module, a filtering module, an optocoupler module and a processor, the input end of the voltage reduction module is connected with a live wire, and the output end of the voltage reduction module is connected with the input end of the anti-surge module; the output end of the anti-surge module is connected with the input end of the voltage stabilizing module, the output end of the voltage stabilizing module is connected with the grounding end of the vehicle body, the input end of the current limiting module is connected with the input end of the voltage stabilizing module, the output end of the current limiting module is connected with the input end of the filtering module, and the output end of the filtering module is connected with the grounding end of the vehicle body. The signal output end of the optocoupler module is connected with the detection signal input end of the processor. Once the detection signal input end detects low level, it is judged that the input PE line is normally connected, and when the detection signal input end detects high level, it is judged that the input PE line is disconnected, and disconnection detection of the input PE line of the charging pile is met.

    本发明涉及一种充电桩输入PE检测系统、充电桩及充电系统,输入PE检测系统包括降压模块、抗浪涌模块、稳压模块、限流模块、滤波模块、光耦模块和处理器,降压模块输入端连接火线,降压模块输出端连接抗浪涌模块输入端,抗浪涌模块输出端连接稳压模块输入端,稳压模块输出端连接车身接地端,限流模块输入端连接稳压模块输入端,限流模块输出端连接滤波模块输入端,滤波模块输出端连接车身接地端,光耦模块信号输入端连接滤波模块输出端,光耦模块信号输出端连接处理器的检测信号输入端。一旦检测信号输入端检测到低电平即判定输入PE线正常连接,检测信号输入端检测到高电平即判定输入PE线出现掉线,满足了充电桩所输入PE线的掉线检测。
