The invention provides an alternating current charging pile control system. The system is characterized by comprising an MCU main control chip, and the MCU main control chip adopts STM32F427VGT6, andis respectively connected with a power supply circuit, an output short circuit detection circuit, a temperature sampling circuit, a communication module, a relay control circuit, an adhesion detectioncircuit, an AC leakage protection circuit, a DC leakage protection circuit, a CP sampling circuit, a man-machine interaction module, an electric energy metering circuit, a voice function module, a grounding detection circuit, a reserved interface circuit, an emergency stop switch circuit and a lightning protection circuit. According to the invention, functions of overvoltage protection, overcurrent protection, undervoltage protection, electric leakage protection, short-circuit protection and lightning protection are realized; and the system has a charging expansion protection function: the MCU tries to realize over-temperature protection at the interface through a temperature detection circuit at a charging connector connection interface. The protection function is the function lacked bythe existing charging equipment and is also the urgently needed function, and the potential safety hazard caused by the lack of the function is often exposed in the existing products in the market.

    本发明提供了一种交流充电桩控制系统,其特征在于:包括MCU主控芯片,所述MCU主控芯片采用STM32F427VGT6,分别连接电源电路、输出短路检测电路和温度采样电路、通讯模块、继电器控制电路、粘连检测电路、AC漏电保护电路、DC漏电保护电路、CP采样电路、人机交互模块、电能计量电路、语音功能模块、接地检测电路、预留接口电路、急停开关电路和防雷电路。本发明具备过压保护、过流保护、欠压保护、漏电保护、短路保护、防雷保护功能;具备充电扩充保护功能:MCU通过充电连接器连接接口处的温度检测电路试现接口处过温保护。该保护功能是目前充电设备缺失的功能,也是急需的功能,市场现有产品经常暴露出缺失此功能后导致的安全隐患。
