Alternating-current charging pile control system

Abstract

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.

Description

technical field [0001] The invention relates to an AC charging pile control system. Background technique [0002] Electric vehicle intelligent AC charging pile is a power supplementary facility for new energy electric vehicles. By communicating with the car, monitoring, control can reliably charge the electric car. The pile has at least the function of charging reservation, the function of adapting to various vehicles, the detection of vehicle status, full protection, overvoltage, undervoltage, overcurrent, overtemperature and other protection functions, metering and billing functions, and various Identity recognition function, with data collection and remote control functions. [0003] At present, there are many types of charging piles on the market, but they have single functions, single protection measures, or even no protection measures; there is a contradiction between perfect functions and cost control; there are defects in the flexible configuration of models, and i...
