The invention discloses a split eight-gun electric automobile direct current charging pile and overvoltage and undervoltage protection system, the split eight-gun electric automobile direct current charging pile comprises a charging pile body, the charging pile body comprises a main cabinet and direct current charging piles, the number of the direct current charging piles is four, the main cabinet and the direct current charging piles are connected through cables, and a control system is arranged in the charging pile body. The control system comprises a rectifier module, a voltage transformer, an overvoltage and undervoltage protection module and a communication module, the rectifier module is used for rectifying three-phase alternating current input and then outputting direct current, and the voltage transformer is used for sampling a charging voltage value and outputting a high-voltage electric signal and a low-voltage electric signal. In the charging process, when the voltage is too high or too low due to voltage abrupt change, the overvoltage and undervoltage protection module can be used for receiving a voltage signal to automatically start a protection mode, cut off a circuit and output an alarm signal, overvoltage and undervoltage protection is provided for a power storage battery of an electric automobile, and the performance is stable.

    本发明公开一种分体八枪电动汽车直流充电桩及过欠压保护系统,包括充电桩本体,所述充电桩本体包括主柜和直流充电桩,所述直流充电桩设有四组,所述主柜和直流充电桩通过电缆连接,所述充电桩本体内设有控制系统,且控制系统包括整流模块、电压互感器、过欠压保护模块和通信模块,所述整流模块用于对三相交流电输入进行整流,再输出为直流电,所述电压互感器用于采样充电电压值并输出高压电信号、低压电信号;本发明在充电过程中,电压突变导致电压过高或过低时,能利用过欠压保护模块接收电压信号自动开启保护模式,断开电路并输出报警信号,对电动车的动力蓄电池提供过欠压保护,性能稳定。
